Global Crisis

This CCS DC Quick Charge station is located on my property at 148 Valley Road, Montclair, NJ

Back in August I posted an article that announced the opening of the first DC fast charger in the East Coast Express Charging Corridor. That station was installed in Hartford, Connecticut. The Express Charging Corridor when completed will connect Washington, DC to Boston, Massachusetts with CCS DC fast chargers, located no more than 50 miles apart, and is being funded by a joint venture between BMW, Volkswagen and ChargePoint.

About three weeks after the station in Hartford was installed, I installed one on my property in Montclair, NJ. It was the first public CCS station in the state that wasn't installed on BMW property. BMW has had a few CCS fast chargers at their North American headquarters for a few years now, as they have been testing CCS since 2012, when they were using a modified BMW ActiveE with CCS capability as a test mule for the then yet-to-be-released i3.

So far the DCQC station is getting plenty of use from i3 owners

CCS fast charge infrastructure had a slow start, frustrating many i3 owners. It was difficult to watch the Asian standard CHAdeMO stations and Tesla Superchargers continue to proliferate, while CCS stations were as rare as White Rhinos. However the pace of CCS deployment has really picked up, and with the East and West Coast Express Charging Corridors beginning to take shape, it's starting to look like CCS is finally getting some traction.

The station I installed is the smaller of the two that will be used in these corridors. I have the 24kW, CCS only DC fast charger but there is another unit that will also be deployed on many of the direct highway locations. That unit is a dual head, CCS and CHAdeMO station and is capable of delivering up to 50kW. Because of the location on my property (not situated on a highway), and the primary tenant is a restaurant where people typically spend an hour or more, the 24kW unit made more sense, and it costs a LOT less. The lower power draw will also help me to avoid or minimize demand charges from my electric provider.

The eGolf owners were very pleased when they realized the DCQC in my lot was close to the route they planned to take to Massachusetts. They only had to drive a few miles off of their route to stop by and Quick Charge

I installed the station a little over two months ago and it's definitely getting use. I've had at least a couple dozen different i3 owners stop by and use it, and I recently had an eGolf owner who was driving from Delaware to Massachusetts stop by to charge up. I was talking to them about the trip and how long it would take to stop and charge at level 2 stations and how happy there were when they saw my DCQC station pop up on the Plugshare map.

Fast charge infrastructure is monumentally important for the mass adoption of plug in cars. Tesla knew the success of the Model S, and probably even the entire company, would hinge on how quickly they could cover large swaths of the US and other key markets with Supercharger access. They have been installing them at an incredible rate, and have installed more than 500 worldwide in under 3 years.

Nissan has also done their fair share with regards to DC fast charge infrastructure and has subsidized much of the costs of hundreds of CHAdeMO installations. Personally, I'm hoping Volkswagen steps up and commits to installing even more infrastructure than the current plan in light of the current dieselgate scandal. Making a commitment to assisting the proliferation of cleaner electric cars would be a good first step in restoring public confidence at this point.

We are getting there. EV charging infrastructure, both level 2 and DC fast charge, is still really in its infancy, but we're definitely making progress in some areas of the country (mainly the coasts). I remember back to 2009 when I was driving my MINI-E and there wasn't a public charging station within a thousand miles of me. In fact, the closest one may have even been 3,000 miles away in California.  Now there are tens of thousands of them in the US. I can only imagine how things will look in another five or six years.

The Plugshare map on the left shows only CCS DC Fast charge stations on the East Coast. Just a year ago at this time there were none in this view. Within a couple of months, there will be dozens more of them as the Express Charging Corridor locations are finished. The large gap south of my restaurant (the blue dot) will hopefully be closed by year's end. The pace of CCS deployment is definitely picking up, and I believe will only continue to accelerate from here on.

Fill 'Er up!

I know many readers here have spent countless sleepless nights pondering the the age-old question: How long does it take to refuel a BMW i3's tiny gas tank?

Well maybe not, but I have had people argue that driving the i3 REx on an extended trip would be very inconvenient because they would have to stop to fill up the gas tank every 50-60 miles. I've done quite a few road trips with my i3 REx, and stopping once an hour for a couple of minutes to refill the tank never really bothered me much.

I wrote a post last year which detailed a 462 mile round trip I made to Vermont from my home in New Jersey and refueling was one of the topics that many people commented on. On that trip, I had to stop for gas a total of seven times, as I only recharged the car once, which was at my destination. I drove 111 miles on battery, 351 miles on the range extender and used a total of 9.87 gallons of gas, averaging 35.5 mpg.

It was snowing in Vermont when we arrived

In that post, I wrote that I found it funny how quickly the gas tank fills because it's only 1.9 gallons. My wife started timing how long it took to stop for gas and we averaged a little over two minutes. I remember wishing we had recorded one of the gas breaks so we could demonstrate just how quick you can pull off the highway, fill up, get back into the car and back out onto the highway. I made a note that the next time we drove back up to Vermont, we would do just that.

So last week we made the Vermont trip again, and as planned we recorded one of the gas stops:


As you can see, I started the stopwatch before we exited the highway, and stopped it when we were back on the highway. I didn't jump out of the car and rush like a NASCAR pit crew filling up. I took my time and even spent a couple extra second topping off so I'd get every drop that I could into that tiny tank and we still did it in under two minutes.

The point of the exercise was to demonstrate that it's really not that inconvenient to make a quick gas break about once every every hour. I will qualify that statement with the fact that here in the Northeast there are gas stations everywhere. It seems that I'm never more than a couple miles from one, so when I'm doing these long drives I can plan the stops at convenient intervals when the tank is nearly empty. While that is the case for many large city and suburban areas throughout the country, there are plenty of rural areas where gas stations aren't as prevalent, and the small gas tank would be a problem. The i3 REx most likely isn't well suited for use in those areas. But hey, BMW calls it a "city car" after all.


As I mentioned above, when I made the trip last year I only did 111 miles on battery and drove 351 on the REx. This year I was able to drive 270 miles on battery, and needed only 184 miles with the range extender maintaining the battery state of charge. This was possible because of the always improving charging infrastructure. I was able to stop twice (once each way) at Prestige BMW in Mahwah, NJ and use their new DC fast chargers. Also, on the way home I stopped for a couple hours at a friend's house who just recently installed a 240v level 2 EVSE in his garage. These stops allowed me to more than double the all-electric miles for the trip, and I only needed 4.9 gallons of gas for the 184 miles I drove with the range extender running, as I averaged 37.5 mpg.

I used the recently installed DC Fast Charger at Prestige BMW on both legs of the trip.

I now have over 36,000 miles on my i3 after seventeen months of ownership, and only about 1,750 of those miles were on the REx. The range extender has been a great feature and I'm still very happy I got it. It does what it is supposed to; it gets you home without worrying about finding a charging station on the rare days that the electric range isn't enough, and it enables the occasional long road trip. There are limitations though, and extreme hill climbing while the REx is running for prolonged periods at highway speeds, can result in reduced power. Fortunately I've never had that happen to me but I don't really have any big mountains which I need to climb. On my Vermont trips I set the Active Cruise Control to 70 mph and have never had an issue yet, even though there are some prolonged climbs at the end of the trip. I did get the "Reduced Power Possible" warning once though, as the state of charge hit a low point of 2% once. However it held there until I crested the climb and once I was on flat ground the SOC climbed back up to about 6%. I left the cruise at 70 mph because I actually wanted to see at what point it would go into reduced power mode, but it never happened.  

On one climb, I was able to get the SOC down to 2% and at that point the car warns you that reduced power may occur if you continue without altering your driving. Basically it's saying "Slow Down!"

Still, in a perfect world I'd prefer a 150 mile, all-electric-range i3 combined with adequate DC fast charge infrastructure. Personally, I really don't need 250 or 300 miles of range, and I'd rather not pay for it. However, even though the infrastructure is improving, I think 200 miles of range is probably more acceptable until DC fast chargers are ubiquitous. It appears with Nissan and Chevy poised to bring 200 mile EVs to market in the coming year, the "affordable" electric vehicle market is going to get very interesting. BMW's CEO recently announced that the 2017 i3 will have a longer all electric range also, but didn't comment on exactly how much more. That's good news because as much as I like how the REx works, and how quickly I can refill the gas tank, I'd still much prefer going on battery alone. 

An i3 sits next to a 24kW DC Fast Charge unit during the announcement of the BMW, VW & ChargePoint joint venture earlier this year.

It's been seven months since BMW, along with Volkswagen and ChargePoint announced a joint venture which would install roughly 100 DC fast charge units on the East and West coasts. While there's been a lot of work identifying potential locations and negotiating with site managers, there hasn't really been any tangible progress that electric vehicle owners could see.  

The plan is to create "Express Charging Corridors" on both coasts, with DC Fast Charge stations placed no more than 50 miles apart. The East Coast Corridor will connect Washington DC to Boston, Massachusetts and the West Coast Corridor would extend from San Diego, California to Portland, Oregon.  There would be two kinds of DC Fast Charge stations utilized. The stations placed directly on the highway locations of the corridors would be 50kW units, most of which will be dual head CCS & CHAdeMO stations. Then, on secondary locations slightly off the direct corridors, 24kW CCS-only units will be placed. While these 24kW units aren't necessarily quite fast enough to be convenient for long distance travel of hundreds of miles, they are very useful for intercity travel and charge at three to four times the speed of standard level 2 public charging.

ChargePoint's East and West Coast Express Charging Corridor Infographic

I applied, and was recently approved under the program guidelines to have one of the 24kW units installed on my commercial property in Montclair New Jersey.  I'm currently awaiting the permits to be approved and hope to have the station installed and working before my National Drive Electric Week event on September 12th. Always the competitor, I was also hoping to be the first East Coast public location in the program to get a station installed, but I'm actually happy to report that won't be the case. That's because a friend of mine and fellow BMW i3 owner, Bruce Redman Becker has beaten me to it. Bruce, and architect and developer, is responsible for 777 Main Street in Hartford Connecticut, a newly developed 285 unit apartment building with a 250 car parking garage. In describing the location to me, Bruce had this to say:

An i3 using the DC Fast Charger at 777 Main Street, Hartford Connecticut

Delivery day: May 21st, 2014

Well that went by fast. After waiting patiently for years for BMW to bring the "Megacity" car, their first production electric vehicle to market, my first year of ownership really flew by quickly. On May 21st of last year I was the first i3 REx delivery in the US. My one year review is about a month late, but that has only given me some more time to gather my thoughts about it.

About a month into ownership last year, I authored two posts dedicated to my initial likes and dislikes. Many of those initial thoughts still hold true, but I've also had some changes of opinion as well as discovering new annoyances and new attributes which I appreciate.

One of the few pictures I have of my car in its real color; Laurel Grey. I wrapped it red the first week I had it.

Overall I'm very happy with my i3 and there isn't another car I'd prefer to have. It really suits my needs while offering the perfect balance of performance, utility, comfort and efficiency that I desire. I managed to pile up a little over 25,000 miles by my first year anniversary (I'm up to about 27k now) with 23,700 miles on battery alone and 1,300 miles with the REx engine running. That equates to about 95% all electric miles. I'm sure some will question whether I needed the range extender option at all since I only used it for about 5% of my driving and that's a valid question. I guess I didn't really need it, but I definitely don't regret spending the additional $3,850 for it and I'll explain why.

The REx performed perfectly on my 462 mile road trip from New Jersey to Vermont. Going there and back I drove a total of 111 miles on battery and 351 on the REx, needing a little under 10 gallons of gas for the trip. I'll gladly replace gassing up on long trips with a couple 30 minute quick charge stops once the infrastructure matures, but for now the REx is my best option for the occasional long trip.

First and foremost, the range extender allowed me to take the car every day without even thinking twice about whether I had enough range or whether or not I would have the opportunity to plug in during the day. Back when I did my initial likes and dislikes, the first thing I pointed out was that I think BMW missed an opportunity to separate themselves a bit from the pack of "80 mile EVs" out there. The 81 mile EPA range rating for the BEV i3 was just a little too low for me so I went for the REx. As it turns out, there weren't too many days which I needed the REx, but having it there allowed me to take the car on days I may not have because I wasn't sure how far I might need to drive that day. So in reality, the range extender allowed me to drive more electric miles than if I didn't have it. I'd say I probably only needed the REx about two or three times a month on average, and even then it was usually for less than twenty miles. There were a couple long road trips which accounted for the majority of miles, and a few times I needed it for 30 to 50 additional miles. When I first got the car I took it to get wrapped and the shop was about 130 miles from my house. The drive back was nearly all on the range extender. I took a couple 150 to 200 mile round trips, my wife took the car on a business trip to Pennsylvania and I also made a 462 mile round trip to Vermont. It's true I could have managed without the REx, but having it there increased the utility of the vehicle immensely and if I had it to do all over, I would definitely get the REx again. However, if BMW had optioned it with a 28-29kWh battery pack (33% larger), I would definitely choose that over the REx.

The car is holding up well and there are no squeaks or rattles to report. My interior still looks brand new, even with heavy use and high mileage for one year. I'm pointing that out because I have heard a few i3 owners report their leather seats showed premature wear, and even a couple people say the eucalyptus wood dash panels developing cracks (which BMW replaced under warranty). I have nothing negative or unusual to report on this though. Since I wrapped the car shortly after getting it, I can't really comment on how the exterior painted surfaces are fairing. Since this is the first BMW with all plastic body panels, and since BMW developed an entirely new way of painting the panels which uses 70 percent less water and 50 percent less energy than painting systems employed for their steel body panels, I think it's fair to wonder how well the painted panels will hold up over time. I have had a few people ask me how the wrap is doing and I can say that after a year of driving in New Jersey (including a harsh winter with a lot of snow and ice) the wrap is beginning to show signs of wear and even peeling on some of the corners. You really have to be looking at it hard to find the problem spots, but small issues are surfacing which I'm sure will only get worse. I really only intended to keep it wrapped for a year or so, so I'm not concerned. I figured this would happen after about a year. Just keep this in mind if you are planning to do a vehicle wrap. 

The wrap is bubbling a bit on the side mirrors

Wheel well beginning to peel

The redesigned fuel sensor

Over the year I had a couple of maintenance issues which needed service. The good thing was my dealer, JMK BMW, has i3s in their loaner fleet so I was able to drive an i3 even when my car was in for service, which amounted to a total of 14 days. The first issue was one that all the early i3's had, a blown onboard charger, or as BMW calls it, a KLE (Komfortladeelektronik or Comfort Charging Electronics in English). One good thing about the way BMW engineered the onboard charging is that there are two 3.7kW on board chargers, one in the main EME (Electrical Machine Electronics) and the other, the KLE, is installed separately from the EME. So if you do have a KLE failure, you can still charge the car, albeit at half speed. I can't give BMW a pass on this issue though. They had five years of field testing with the MINI-E and ActiveE, and to come out of the gate with a faulty on board charger is inexcusable in my opinion. To their credit, they quickly resolved the issue by re-engineering the KLE, and installing it in the existing i3 fleet. I've had the new KLE  in my car for 10 months now, and it's been working fine. There was another issue that all i3's with the range extender had, which was a faulty fuel pressure sensor. Almost immediately after the i3 launched, REx owners were getting a Check Engine light, even if they never fired up the REx. It turned out a fuel pressure sensor was getting corroded by the gasoline used in the US. Evidently the mixture is different from the gas used in Europe where the i3 had launched 6 months earlier without this issue, and the additives in the US gas were creating havoc with the sensor. Again BMW quickly made a new fuel pressure sensor, this one actually has gold plated connectors to resist corrosion.

My battery pack dropped from the car. The heating element is inside, below the battery modules

I also had a flaky voltage regulator for the battery heating element which was occasionally sending an error message. I don't think BMW was sure if the sensor was bad or if the regulator was bad so they just replaced both. That required removing my entire pack to replace the regulator. I was surprised that this major service was accomplished by my dealer in less than two days. The only other issues I had were flat tires; four of them to be exact. It's difficult for me to really assess blame on this, since flat tires are usually the fault of the driver for running over debris or adverse road conditions, but four flats in one year is a little troublesome. Could it be related to the rubber compound Bridgestone used to make these unique tires, or related to how tall and thin they are? The two main problems I have with this are the fact that since the i3 doesn't have a spare, you are left stranded unless the mobility kit (an air compressor and tire sealant) can temporarily seal the hole and allow you to drive home or to a repair shop. Secondly, the tall thin tires are unique to the i3, so they aren't always in stock at the dealer. One time I had to wait four days for the dealer to get one. 

With no spare tire onboard, a flat means you're getting towed

At least with a sidewall bubble you can drive to the dealer, but you still need to buy a new tire and hope it's in stock

Three of the four flats I had were caused by sidewall bubbles, which happen when the inner liner of the tire is damaged. Sidewall bubbles typically happen when you hit a pothole, curb or road debris. In all three cases when I had this happen, I hit a good sized pothole and immediately figured I'd have a problem. Pulling over once it was safe confirmed what I had expected. The other flat I had was caused by a large metal screw. In that case I was actually only a couple blocks from a BMW dealer who actually had the tire in stock and I was able to wait there and drive off about an hour later. A few years back I had a Porsche Boxster with low profile Pirelli tires and had sidewall bubble issues with that car also, so I know this is something that is common with low profile tires. The difference was the car had a spare tire and the Pirellis were available everywhere. If I could go back in time I probably wouldn't have gotten the $1,300 optional 20" sport wheels and I certainly would have paid the $1,000 for the tire and wheel insurance. I definitely like the look of the 20" wheels, but they are lower profile than the 19" stock wheels, and that makes them more susceptible to bubbling. 

91 miles on a charge is my personal best to date

As for the range, in warm weather (over 65 degrees) I can usually beat the EPA rated range of 72 miles per charge. In fact, I average about 78 miles per charge in these favorable conditions. The cold weather takes its toll and the worst range I ever got was 48 miles on a full charge before the REx turned on. This happened back in January when the temperature was below zero with ice covered roads and I didn't precondition the cabin or battery. I actually wanted to see just how bad the range could be in those conditions. However most of the winter when temperatures were under 30 degrees I averaged about 58 to 60 miles per charge. The furthest I ever drove before the REx kicked in was 91 miles, which I did shortly after taking delivery.

I'll now list the top ten things I either find annoying, would like to see corrected or added features to future i3s.

1) Configurable regenerative braking. I'd like to select how aggressive or weak the regenerative braking is. Other manufacturers offer this and the owners I've spoken with appreciate having control over their regen. The i3's regen does increase in strength when in Eco Pro and Eco Pro+ modes, but I'd prefer the ability to manually adjust it.

2) The car needs an extension flaps on the sun visors. There is a huge gap between the visors and early morning drives can be difficult when heading East. 

3) The charging connector needs to unlock from the vehicle when the charging session ends. BMW had said this would be part of the March 2015 software update (which I have) but it still doesn't work. 

The large gap between the visors allows the blinding sun to get through. Visor extension flaps would be appreciated.

4) The front storage compartment (frunk) should be waterproof. If that is problematic then install a snap-on or hinged cover to keep dirt and water spray out. 

The current configuration allows leaves, water and dirt to get into the frunk storage compartment. Anything stored up there gets dirty and wet. A cover would solve the issue.

5) Remove the annoying disclaimers and seat belt gong every time you turn the car on.  The seat belt warning should give you ten or twenty seconds to buckle up before it sounds the alarm. I might code my car just to remove these.

6) Fix the windshield wiper. It currently pulls water back into the drivers view when it changes direction. During heavy rains there is a significant obstruction to the drivers view of the left side of the windshield. 

The wiper leaves a line of water on the windshield, and actually pulls it back into the drivers line of vision when it changes direction.

7) Add a battery temperature readout. BMW can bury it in iDrive if they don't want it on the main display screen, but put it somewhere. Many experienced electric vehicle drivers want to see their battery temperature.

8) Add a heated steering wheel. In my opinion heated seats and steering wheel should be standard on all EVs, especially ones from premium brands. I would have really appreciated it last winter.

9) Include an AM radio. Other EV manufacturers have figured out how to reduce the interference and offer it in their vehicles. I'm sure BMW can figure this out too, even if the reception isn't perfect. 

When the ACC disengages, you get this warning. The problem is by then it's already disengaged and the car is applying the regenerative braking.

10) Fix the Adaptive Cruise Control and Parking Assistant. These are really great features, and this kind of technology is expected in a car like the i3. The problem is the ACC disengages suddenly and doesn't recognize certain vehicles because of their tail light configuration. The car will drive right into the rear of a Dodge Charger for instance, because the Charger's taillights (which extend across the entire rear of the vehicle) for some reason confuse the ACC. Direct sunlight and sometimes overpasses also cause the system to shut off without warning. I dedicated a post to this issue a few months ago. The Parking Assistant is an automated parking feature which does an incredible job of parking the i3 in very tiny parking spots. It only needs an opening which is 22 inches longer than the car to park it. The problem is, I've had numerous people report to me that the car rubbed the curb during the automated parking, scratching the rims. I've had enough people tell me this happened to believe it wasn't just a couple cars malfunctioning. I believe there is an inherent flaw in this feature which needs to be fixed, so for now I recommend not using the Parking Assistant until we get word that the issue had been corrected. 

OK, so by now you must be thinking I must really hate the i3, considering all these things I've pointed out that I don't like. That wouldn't be correct. I actually love the car and wouldn't trade it for anything, but nothing's perfect, and BMW can definitely make adjustments which would improve the i3 in my opinion. Now I'll dive into my top ten i3 likes. 

1) Spacious interior. For a car that is only 13 feel long, it has a lot of interior room. It actually has nearly the same interior volume as a 3-Series which is more than two feet longer than the i3.

Spacious, comfortable and well laid out. The i3's interior is definitely one of its strong points

2) Beautiful interior. In my opinion the i3's interior is stunning and laid out perfectly. The seats are very comfortable and the outward vision is excellent.

3) It's incredibly fun to drive. The instant torque, combined with the light weight make the i3 the most fun to drive electric vehicle this side of a Tesla P85D. The low end acceleration (under 60mph) is fantastic and it's actually the fastest one of the fastest BMWs from 0-30mph. Somehow the tall, thin tires do their job and keep the car under control in hard turns. While it doesn't corner like an M3, it really does just fine when it needs to. I've let dozens of friends and family members drive it and they all walk away with an ear to ear grin. It's really a blast to drive.

4) Futuristic, sustainable construction. I love the fact that I'm driving the only volume production to ever be constructed with a passenger compartment primarily made of carbon fiber reinforced plastic, an all aluminum frame and thermoplastic body panels. There is absolutely nothing else like it on the road today. Plus, every stage of manufacturing and assembly was developed with sustainability in mind.100% of the electricity used in the Leipzig assembly plant is derived from the wind farm BMW installed on the site. It actually generates so much excess electricity that BMW sells the excess to the Volkswagen AG. Even the carbon fiber plant in Moses Lake, Washington where the CF is made is powered 100% by renewable hydro-power. 

BMW's Leipzig plant where the i3 is made. The on site wind turbines produce more energy than the plant uses.

5) The charging rate. I can consistently pull 7.2kW at home (30 amps @ 240v) and now that there are finally some CCS DC fast Chargers being installed I can look forward to fast charging on the go. I'll soon be installing a 24kW CCS DC Fast charger at my restaurant so I'll have access to it every day. One of the advantages of having a relatively small battery is it charges quickly! I can fully recharge in a little under four hours while charging level 2, and I can be at 90% in about three hours. Tesla is the only EV manufacturer in the US making on board charging equipment which can deliver more than 7.2kW from a level 2 (240v) source.

6) The efficiency. According to the EPA, the i3 is currently the most efficient car sold in America. Over the entire year I averaged 3.9 miles per kWh. In the warmer weather I'm usually around 4.5 mi/kWh and in the winter I was averaging about 3.5 mi/kWh. I should note that I don't drive the car softly, and I'm certain many other i3 owners see much better consumption figures. It's way too much fun to drive it like it was a Prius. Averaging 4 mi/kWh the i3 would cost the average American about $400 per year to drive 15,000 electric miles.

I needed to drive over 200 miles on the range extender when I drove it to Vermont last winter. I set the cruise control to 70 mph and the REx was able to sustain the charge level the entire trip without any issue, even with needing to make a few elevation climbs.

7) The range extender. I know above I said I'd prefer a larger battery over the REx, but that just isn't an option at this time. As far as range extenders go, I like how BMW set this one up. It's truly an auxiliary power unit, one that has no physical connection with the wheels and cannot drive the wheels under any condition. It's sole purpose is to maintain the battery state of charge and allow the driver to continue along until they have the opportunity to plug in. You'd never buy an i3 REx and not charge it, simply driving on gas all the time. It's not meant to drive just as well on gas as it is on electric and I like that. It's an electric car with a secondary power source meant for occasional use, and in that vein it works perfectly - well for me at least. In all of my REx-ing, I never had the vehicle go into reduced power mode which can happen if you are using more energy than the 650cc engine can deliver. This can happen under long sustained hill climbing at highway speeds. BMW is currently working on a solution which will allow for more robust range extender use. This feature will be called Hill Climb Assist and will be available in the Fall. All current REx cars will get the update. There is another option which some owners have done, and that's coding the car to allow REx-on-demand. I have not done that to my car because the range extender has been able to do anything I've called for it to do so far, and I've found that as long as I set the cruise control for 70 mph or lower, I can drive indefinitely, provided I keep refueling every 60 miles or so. Probably the best thing I can say about the range  extender is it's allowed me to never even think about my range anymore, I just get in the car everyday and drive. 

Resting at home. You can see the winter tire/wheel combo on the rack above the car. The Bridgestone Blizzak tires were excellent in the snow. I suspect this was an instance where the tall, thin tires actually improved the traction.

8) The attention. Everywhere I go people stop and ask me about the car. I understand many people might not like that, but I do like talking about it and having a discussion about why they should consider driving electric too. I know there are people who think the i3 is ugly, but the response I get from the majority of people is they think it's cool. I don't think the i3 is the best looking car on the road, but I definitely don't see it as ugly and neither do most of the people who stop me to ask about it. When I'm working I can see it through the windows in the parking lot. Every day people walk up to it, look inside and many take pictures of it. Like it or not, it generates a lot of interest.
9) Battery management system & preconditioning. The i3 has a sophisticated thermal management system which works with the preconditioning feature to keep the batteries within the optimum operating temperatures. Which, for the Samsung cells used by BMW is 67 to 104 degrees Fahrenheit. When the batteries are much cooler than 67 degrees, you begin to lose range and when the battery temperature is above 104 degrees the cells degrade and begin to lose capacity. Excessive heat can be one of the biggest enemies for prolonging lithium ion battery life so a good thermal management system will help extend the battery's life. The i3 uses R134a refrigerant which not only works very well, but also is extremely safe in the event of an accident. Liquid based thermal management systems have an elevated risk of fire in the event of a battery module rupture. In many of these systems it's possible for the liquid to act as an accelerant, and intensify the fire. R134a is an inert gas and simply dissipates in the event of a ruptured pack or fire. It's actually the same refrigerant used in most car air conditioning systems. I'm not saying I think liquid thermal management systems aren't safe, because that's not the case. I just believe using an inert gas is better, and the i3 is the only EV to employ this technology so it's worth noting. It's just another aspect of the car which demonstrates how far outside the box BMW went when engineering the i3, and a perfect example of why the i3 has been called "The most advanced vehicle on the planet".

The i3's navigation "spider map" offers a pretty accurate visual display on the cars current range in the different driving modes.

10) A lot of small things add up to really enhance the ownership experience. Besides the usual attributes expected in all electric vehicles like the quiet cabin and the smooth linear acceleration with instant torque, the i3 has some extras that really seem to make the whole car exceed the sum of its parts. I love the hill hold feature which keeps it from rolling like many other EVs do while stopped. The absence of artificial creep is a welcomed "addition" that some other EV manufacturers just don't seem to get. I've done more than one poll on this topic and the vast majority of people say they don't want artificial creep in their electric vehicle and BMW got this right. I love how the aggressive regen really allows "one pedal driving". While I did mention above that I wish the regen was adjustable, the level it's set at now is just about perfect for me in most driving conditions. Adjustable would be better, but as is the regen level is very good, probably the best of any electric vehicle in my opinion. The soft speed limiter helps to coach you to drive more efficiently if you want to, and the three different driving modes (Comfort, Eco Pro & Eco Pro+) gives the driver the ability to extend their range significantly. The "spider map" display in the navigation system shows how far the car can go in each driving mode, and alerts the driver if their selected destination is beyond the range, pointing them to possible charging stations along the desired route. The brake assist will sound an audible alert if it senses the car is rapidly approaching the vehicle in front of it and it will even apply the brakes automatically if you are going under 30 mph and it determines you are about to have a possible collision. I also really appreciate that most BMW dealerships now have i3s as loaner cars so i3 owners can continue to drive electric even if their car is in for service. Finally, the large center display screen is as crisp and clear as any I've seen. It is positioned so there is almost no glare issues and the HD rear view camera is television-quality clear.

The "Secret Service Menu" shows I have 19.1 kWh available when fully charged

So that pretty much sums up my thoughts after one year of ownership. I listed ten positives and ten negatives and hope the information above helps to paint a picture of what I believe are the i3's strengths and weaknesses. One more topic I'd like to touch on though is battery degradation. There are a lot of people curious about how well the battery is holding up over time and use. I'm going to be doing a more comprehensive post on this soon, but I'd like to at least mention what I've observed after 13 months and 27,000 miles. Fortunately, the i3 has a "secret service menu" in the OBC which allows the battery capacity to be displayed. While BMW officially states the i3 has a usable 18.8 kWh of the 21.6 kWh total battery pack, the service menu indicates we get a little more to access. An entire kWh more in fact. When new, the service menu shows approximately 19.8 kWh available. I've had others report seeing slightly less, but the majority of people who know how to access this info have told me the highest capacity figure they've seen was 19.8 kWh. I have been checking my capacity and watching it slowly decrease. It's currently showing that I have 19.1 kWh available, which would mean I've lost about 3.5% of my capacity in 13 months and 27,000 miles. I've plugged about 700 times during the year and virtually always charge to 100%. I'll be keeping an eye on this and will report back on the capacity loss here from time to time.

I have an 8.8kW solar array on my home in Chester, NJ. It generates most of the electricity I use for the house and charging needs.

I'd like to also point out that during the year, BMW added a numeric state of charge display. This was something I, and many other i3 owners asked for. It might seem like a minor detail, but what's most encouraging is BMW responded to their customer requests and through a software update added the SOC display. Of course there was always a SOC display there, in the form of a bar graph, but many people wanted to see it displayed more precisely, in a numeric value as well and BMW delivered. Now let's see if we can get the battery temperature display in year two...

By toggling through the OBC options, you can see the SOC of 47% in the upper left hand corner of the drivers display screen.

In closing, the i3 pretty much ended up as I expected. It's far from perfect, but so is every other car I've ever driven. I wish it had a larger battery (or a larger battery option), a few monochromatic paint scheme options (like I did with the wrap), offered in a "sport" version with the coilovers that come standard in the Japanese market and a few other sporty upgrades and I think BMW needs to address the issues with the ACC and Parking Assistant features. I don't mind that the moonroof isn't available in the US, and the unconventional exterior styling doesn't bother me. I am much more concerned with the car's interior since that is what I interact with while driving. Speaking of driving, for me it really all comes down to that. The i3 delivers more fun than you should legally be allowed to have at 4 miles per kilowatt-hour.

With the proliferation of electric vehicles like the i3, the absence of a robust fast charge infrastructure becomes more and more difficult to ignore. There are indeed areas of California which are served very well with DC Fast Charge stations, however for many EV owners outside California, Fast charge stations are something they only dream about. Georgia however, has been making some great progress with DCFC. Georgia resident and i3 owner Chris Campbell tells us what's happening with DC Fast Charge in the Peach State.

Chris with his Volt back in 2010

You may remember Chris from a post he made here last year. Chris was the very first Chevy Volt owner in Georgia back in 2010. He authored a guest blog post here telling his story and why he had decided to get a BMW i3 when he turned in his Volt. Many i3 purchases have come from buyers which were early adopters and had leased an early Volt or LEAF. Chris has been active in the Atlanta area's EV scene for a while and maintains a website full of EV information, which can be found here: www.http://electrifyatlanta.com
__________________________________________________________________________


For over a decade, Georgia has offered a generous $5,000 tax credit in support of getting an electric vehicle (EV). But only in the last three to four years has the market offered affordable cars with usable range, and suddenly huge numbers of Georgians have taken advantage of that incentive. In the last session, the state legislature took notice of this growth and killed the tax credit altogether, with it officially ending this month. June 30th is the last day that Georgians can get an EV (purchased or leased) and still be able to claim the credit when filing taxes next year.

So there is now one last mad rush to take advantage of one of the best EV incentives in the country. Potential EV owners are making their final decisions and dealers are scrambling to respond to demand and maintain inventory.

BMW i3 owner "heat map" illustrates Atlanta hot spot

The Nissan Leaf, by far the highest volume EV in the Georgia market, continues to dominate sales, but the BMW i3 has also enjoyed success in the Atlanta market, as illustrated by this "heat map" showing locations where owners voluntarily listed themselves on the i3 owner map. Atlanta is a true hotspot for EV ownership, and has an active i3 owner group!

NRG EVGO station at Mall of Georgia, CHAdeMO only

Besides the state tax credit, however, there has been another factor energizing EV uptake in Georgia: a large and accelerating roll out of DC Fast Charging (DCFC) stations. The first DCFC stations (CHAdeMO for Leafs) arrived in north Georgia in July 2013 via The EV Project (aka Blink), but the CHAdeMO rollout really accelerated in November 2014 when NRG entered the Atlanta market with their EVGO CHAdeMO stations. As of this writing there are now over 30 CHAdeMO stations in the metro Atlanta region, with another dozen expected online in June.

Two competing DCFC plug standards, SAE Combo (left) and CHAdeMO (right)

Of course, as most EV owners know, there is not just one DCFC plug standard -- there are three!  In 2008, before the current wave of EVs, the automakers all (except for Tesla) agreed on a Level 2 standard, the J1772 plug that is now familiar to all EV owners. But they did not come to an agreement on DCFC (sometimes inaccurately called Level 3), and so the EV market split into three camps:

- Nissan and other East Asia automakers: CHAdeMO
- Tesla: Proprietary Supercharger
- Everyone else including BMW, VW, GM:  SAE Combined Combo System (CCS)

Since that market split, the three different camps have proceeded with their respective DCFC station rollouts, with Chademo and Tesla fighting for the lead and SAE Combo in a distant third. However, we have started to see "dual standard" DCFC stations hit the worldwide market, offering both CHAdeMO and SAE Combo. While these stations do not directly support the Tesla interface, Tesla owners can now buy a $450 adapter from Tesla Motors, that lets them charge from CHAdeMO stations. So these dual-standard stations effectively support all three standards. Of course Tesla cars have far larger batteries, offer far more range, and typically take advantage of their own network of ultra-fast DCFC stations.

BMW-branded DCFC unit, SAE Combo only, 24 kW

The SAE Combo flavor of DCFC (compatible with the BMW i3) first appeared in Atlanta in late 2014, with a single dual-standard cabinet at a Georgia Power testing facility, unfortunately accessible during weekday business hours only. In January a second SAE Combo unit appeared at BMW NA's offices, however that BMW-branded unit only offers 24 kW peak power. Obviously with just these two i3-compatible DCFC stations, one with limited access and the other offering low power, and both located in the same side of town, they were of limited utility to i3 owners.

It was not until this week that the true potential of the BMW i3 was realized in the north Georgia market, with a wave of SAE Combo DCFC sites going online.

Georgia Power's first dual-standard DCFC station

Following nearly a year of planning and construction, regional electric utility Georgia Power has now launched their network of DCFC stations, which are DUAL-STANDARD. These new stations offer both CHAdeMO and SAE Combo plugs, and thus are able to charge every DCFC-capable EV in the U.S. (even the Model S via Tesla's new adapter).  Georgia Power's DCFC sites deliver 50 kW and will offer Level 2 charging stations as well. Their network launched in May with pilot stations at 11 Georgia Power locations in 4 cities, and will expand to a total of 60 stations statewide by the end of 2016. The first wave of stations launched temporarily with only CHAdeMO capability, but on June 2nd Georgia Power finally delivered on their promise and brought their first dual-standard station online, with more expected this week.

This is just the first wave. Georgia Power plans to spend 2015 installing 25 more stations at locations around the state, and then another 25 in 2016. Some will be in metro areas, essentially serving commuters, but some will be installed along interstate corridors, serving those EV owners eager to stretch the legs of their new car. Since every one of these stations will offer dual-standard DCFC, these stations will support ALL EV owners. Atlanta-area BMW i3 owners have been straining at the leash for these stations to finally go online, and the day has now arrived.

Pictured at left: NRG's new dual-standard BTC hardware

But Georgia Power is not the only player in the market offering dual-standard charging.  NRG entered the Atlanta market in November 2014 with CHAdeMO-only stations, but recently has been expanding their presence with dual-standard DCFC stations made by BTC Power. Unfortunately, while these BTC stations have internal hardware that supports both CHAdeMO and SAE Combo charging, these new stations have been popping up with the SAE Combo side disabled. It is rumored that NRG (and partner Nissan) have asked BMW to chip in on the cost of these stations. If that is indeed the case, I believe it would be wise for BMW to step up and contribute to this much needed infrastructure.

Signet DCFC cabinet with Greenlots network

A similar situation is playing out with some state-funded stations. The Georgia Environmental Financing Authority (GEFA) is an arm of the state government that normally funds projects like water and sewer improvements, but in 2014 they announced a grant opportunity for GEFA-funded electric car charging stations at municipalities and educational institutions. Following a frenzied application window that reportedly lasted only hours before the funding was all used up, GEFA delivered on those grants in late 2014, and since then stations have been popping up in locations around the state, beyond metro Atlanta. Three of these locations are Athens, Augusta and Columbus, where GEFA-funded DCFC stations went online in April.  These stations launched with only CHAdeMO capability, despite the GEFA grants specifically requiring dual-standard DCFC. Indeed the Signet hardware that was physically installed did include SAE capability, with even the cord and plug installed and ready to go, but the SAE Combo plug was disabled in software (via the Greenlots activation network). Again it appears that Nissan maneuvered to have the stations installed with SAE Combo, but with that capability disabled until BMW chipped in. Local i3 owners raised this concern with BMW via a variety of methods, and in late May, these three locations saw their SAE Combo plugs quietly get enabled. The rumor now is that this solution will soon spread to similar stations that have appeared in the Carolinas, further enabling regional travel by i3 owners. BMW of North America has made no public statements about what is going on at any of these, frustrating local i3 owners.

Table comparing DCFC cabinets seen in Georgia market

Georgia now boasts EIGHT different makes of DCFC station hardware, operating on six different networks (click here for details on the station hardware now operating). Thus, the state now has one of the most heterogenous DCFC station populations in the world, exceeded only by California, and certainly Georgia can be seen as a great market to evaluate DCFC developments and test car compatibility.

All of this DCFC activity, especially the SAE Combo roll out, has delighted local BMW i3 owners, who have been chomping at the bit to go on road trips in their new cars!

A BMW i3 and a Volkswagen e-Golf charge on DC fast chargers side by side at BMW Headquarters in Woodcliff Lake NJ.

I wrote this article for Green Car Reports, where it was published a few days ago. The proliferation of a robust DC fast charge network is vital to electric vehicle adoption, and I wanted to give this story as wide an audience as possible, which is way I let GCR publish it first. Now that they had it for a while, I'd like to share it with the readers here.

I was invited up to BMW NA headquarters by BMW product manager Jose Guerrero to try out the new DC fast chargers installed there. There are three of them, along with four Level 2 EVSEs, all of which are open to the public 24/7.

A couple weeks ago at the DC Auto Show, BMW, Volkswagen, and ChargePoint jointly announced they would install about 100 DC fast chargers for electric cars. Their goal is to create “Express Charging Corridors,” on both the East and West coasts, by the end of this year. The most intriguing news, however, was that the hardware will--in most cases--offer fast charging for electric cars using two different standards: CCS (used by BMW and VW) and CHAdeMO, used by Japanese and Korean automakers.

The three DC fast chargers at BMW NA HQ are CCS only. The reason being is these are not directly included in the Express Charging Corridors, but secondary locations which are more likely to support local driving, not long distance traveling.

I say “most cases” because not every single location will have a dual-standard fast charger that provides CHAdeMO, although most will. Today, CHAdeMO stations are far more widely installed in certain areas--totaling several hundred in the U.S.--than CCS stations, of which only a few dozen exist today. The "Express Charging Corridor" project will determine whether a desired location is close to an existing CHAdeMO station. If so, that location will provide only CCS cables.

I suspect this may only happen in a few locations, largely on the West Coast, since the East Coast has very few operational CHAdeMO stations to date. The East Coast corridor will connect Boston to Washington, D.C., while the West Coast corridor will extend from Portland to San Diego. Both corridors will have DC fast chargers installed at intervals of less than 50 miles, making it possible--if tedious--to do long-distance trips in electric cars with ranges of 75 to 90 miles, including the BMW i3 and the Volkswagen e-Golf.

Then, less than a week after the DC Auto Show, Kansas City Power & Light announced that it had partnered with Nissan and ChargePoint to install 1,000 electric-vehicle charging stations throughout the greater Kansas City region.


That in itself is fantastic news. But if you drill down into the press release, you will find that only 15 of the stations will be DC fast charge stations--a little disappointing. However, these 15 stations “will charge any model of electric vehicle on the market,” meaning they too will support both CHAdeMO and CCS. So BMW and Volkswagen’s project will provide CHAdeMO charging, and Nissan’s endeavor will include CCS support.

These Efacec units will be installed along the new "Express Charging Corridors" by ChargePoint and support both CHAdeMO and CCS

What just happened here?

Did the automakers all quietly agree to support both standards, so every electric-car driver can benefit? I interviewed BMW’s Electric Vehicle Infrastructure Manager, Robert Healey, on the morning of the DC Auto Show. He told me BMW has no problem with supporting dual-standard stations, because the main goal is to advance the proliferation of charging infrastructure for plug-in cars as rapidly as possible.

CHAdeMO and CCS connector side by side comparison.

He went on to say that in these early stages of adoption, “a rising tide raises all boats”--and this kind of cooperation among competitors is in everyone’s best interest. While he couldn’t elaborate or speculate on the future, Healey said he would be open to similar partnerships with other automakers, should the opportunity arise.

So it's looking more and more as though the DC fast-charge standards war that everyone was predicting may be over, really before the first shot was even fired. I hope so, because if this trend continues, everybody indeed wins. Especially electric-car drivers--not only today's, but the many more to come.
