27 Months & 56,000 Miles: 15,000 kWh of Electricity & 50 Gallons of Gas

Image
Over the course of 56,000 miles, I've driven on pure battery 96% of the time. My 2014 BMW i3 REx is now 27 months old, and the mileage on the odometer just recently surpassed 56,000 miles. I've needed a little over 15,000 kWh of electricity, and exactly 50 gallons of gas to power the vehicle thus far. That means I've driven on pure battery about 96% of the time, and managed an impressive overall gasoline consumption of 1,120 mpg. Normally I wouldn't highlight the gasoline use in my electric car; it's really not something most electric vehicle owners like to do. However, as many Chevrolet Volt owners can attest to, adding a range extender to a short range (under 100 mile AER) electric vehicle can expand its versatility immensely. While I haven't needed to use the REx often, there were plenty of times, especially in the winter, that I was very happy it was there. Back in early 2014, a few months before the North American i3 launch, I openly debated whether I'd...

BMW i Home Energy Storage System Announced at EVS29

Image
Yesterday at EVS29 in Montreal, BMW announced an energy storage system which uses BMW i3 battery packs. The system can utilize a used i3 pack, or it will be able to be purchased with a brand new battery pack. Perhaps the best aspect of the program is the fact that if you own an i3, you can have your old battery pack built into the system when you upgrade your car with a new pack. I've been waiting for this announcement for a while now. I can remember talking with one of BMW's top program managers from Munich three years ago. We were discussing my home solar system, and how I'd been powering my MINI-E and ActiveE electric cars with clean, renewable energy from the system for many years at that point. He then asked me the question, "What do you think will happen to your EV's battery once it has reached its end of life?" I answered that I would imagine it would probably be taken apart and recycled, with the lithium being used for new batteries. To which he said, ...

2017 BMW i3 Specs Revealed With Some Surprises

Image
Fluid Black as pictured and Protonic Blue Metallic will most likely be very popular colors in 2017 While many of the changes that the 2017 BMW i3 will be getting have already been announced; such as the availability of the anticipated 94 Ah battery cells, the new Protonic Blue color and a moonroof option, I've now learned there are also more subtle changes in the US for the new model year. First, and most interesting, is the revelation that BMW will indeed continue to offer the i3 with the current 60 Ah battery, offering a lower range and lower cost i3 alternative. This is something that I don't believe has been reported on any other EV news site to date. I speculated that BMW would do this back in March, when I wrote this post dedicated to the topic. BMW hasn't made any statements regarding offering two battery options, and made no mention of it in the the official press release   of the 2017 i3. Still, my sources tell me otherwise. The 60 Ah i3 will only be offered as a ...

BMW i3 REx Lawsuit: How'd This Happen & Who's Really at Fault

Image
The "Hold state of charge" feature shown here on this i3 display is at the center of the recently filed lawsuit alleging the BMW i3 REx is unsafe to drive. Recently news has spread of a class action lawsuit filed in the state of California by MLG Automotive Law alleging that the BMW i3 REx is dangerous and "can result in a catastrophic situation for all those on the road." This, in my opinion, is grossly misleading. However in fairness, to say the vehicle can be driven like any other car while the range extender is in use is also grossly misleading. To understand the juxtaposition of those two statements takes some explanation. The truth is, the plaintiffs aren't making this up. What they are describing in the lawsuit is called "Reduced Power Mode" and it can happen under certain strenuous circumstances when the vehicle continues, for a prolonged period, to consume more power than the range extender can provide. In this post I'm going to attemp...

Here's Why an i3 Battery Upgrade Currently Doesn't Make Sense

Image
The 2017 i3's 33.4 kWh battery pack is the same physical size as the current 21.6 kWh pack. BMW purposely designed the battery tray this way, so that future battery upgrades would be possible. Allowing the i3's battery to be upgraded was always BMW's plan. The concept of upgrading an electric vehicle's battery pack is certainly not a new one. In fact, it's something that many EV owners have been vocal about wanting to see offered. So the news that BMW will begin a battery upgrade program for their current i3 owners is good indeed, even if it may be something that isn't really necessary, or practical - yet. The big news in BMW i's May 2nd press release was, as expected, that BMW would be upgrading the i3's battery cells from 60 Ah to 94 Ah. This means the 2017 i3 will have an EPA range of 114 miles, up from the current 81 miles per charge. These new battery cells are physically the same size as the currently used cells, but can hold 50% more energy and ar...

It's Official: The 2017 BMW i3 Will Have New Battery, Moonroof Option, New Colors & More

Image
The 2017 i3 comes with 40% more range than the current model. It's also available in a nice new color: Protonic Blue The worst kept secret of the BMW i3 is officially no longer a "secret". BMW has formally announced that the 2017 i3 will have a new, longer range battery pack. They are indeed using the new Samsung 94 Ah battery cells that I speculated they would five months ago . Just as I predicted the new battery pack is increasing from 21.6 kWh to 33.4 kWh, which in an increase in capacity of about 50%. However the range of the i3 BEV will only increase by 40% from 81 miles per charge to 114, which is less than i predicted. That's because BMW is now using a larger buffer (the difference between the total battery capacity and the usable capacity) and also because the car now weighs more (roughly 100 lbs more) because the new higher capacity cells weigh slightly more than the ones they replace.  The slight increase in weight will likely only have a very minor effect o...

Can BMW Fend Off The Charge of the Tesla Model 3? Part 2

Image
My concept 2020 BMW i5. BMW's answer to Tesla's Model 3 (shown in Moloughney Red) Designed in conjunction with BMWBLOG In last week's post , we looked at the impact that Tesla's Model S has had on the sales of competing vehicles in the large luxury segment in the US. That set the table for the question of whether or not the Model 3 can have equal or perhaps even greater success in the entry level, premium segment when it hits the streets sometime in the end of 2017 or early 2018. That segment has been owned by BMW's 3-Series for decades, and BMW isn't going to just give it up without a fight. But what exactly can they do? The Model 3 has captured the imagination of the public and Tesla has received over 400,000 reservations in the first three weeks since the reservation process has opened. That staggering number has undoubtedly caused a few sleepless nights for product planners of various OEMs. In fact, if we look at theory of Diffusion of Innovations , the inte...
