BMW i3 Long Term Battery Capacity Report: Better Than Expected

Image
The heart of any electric vehicle is its battery. This BMW i3 cutaway shows the battery removed from drive module.  When it comes to electric cars, it’s all about the battery. Well, it’s not quite that simple, but given how important the battery is to the cost, range and performance of the vehicle, it’s pretty close. When someone is considering purchasing their first electric car, they will certainly have a lot of questions.   The one question that seems to be on nearly everyone’s list is: “How long will the battery last?” The problem is, it’s been very hard to answer that question authoritatively because we just haven’t had enough data.   That’s because modern electric cars that are powered by high-voltage lithium ion battery packs have been on sale for less than ten years, and long term testing results simply weren’t available.   In fact, the Nissan LEAF was the first high-volume all-electric car brought to market, and that model has only been on ...

BMW i3 Deep Dive Book Now Available

Image
The BMW i3 is anything but the average car. Not only is it BMWs first electric offering, it's also the only car available today that has an optional auxiliary power unit; the range extender. It's really unlike any car that's ever been available, and unsurprisingly, it's often misunderstood. Most people really don't understand how the range extender works; what it can do, and what its limits are. This is, unfortunately even true for many of the client advisers selling them! So getting information on how the  car works out there is very important. BMW has produced a series of videos that help to explain the i3. While very helpful to new owners, they don't go into too much of the technical details that many people are also interested in. The book is filled with graphs on charging, range, power, consumption, etc Enter BMW i3 owner and engineer, David Bricknell. Earlier in the year, David published a book called "Electric Vehicles and the BMW i3" that was ...

Born Electric Guest Post: Meet Francis From Quebec

Image
The following is a guest post written by i3 owner Francis. I started the Born Electric guest post series back in 2014 to give the readers here a look into the lives of i3 owners around the world. To view past Born Electric guest posts, follow this link: Born Electric Hello, my name is Francis and I was born electric two years ago on November 13th, 2014. I opted for the BMW i3 with the range extender and I have been sharing my electric experience with my fellow Quebecers. I even did a lengthy post after my first year that covers pretty much everything. I'm also an owner that didn't code my i3 to change the range extender behavior in North America (some would call me crazy and yet I never had a problem with the REX). So why post again after my 1-year report ? Simply because this year was everything but usual. One question we all asked ourselves, what would happen if my driving habit changed, would my electric car still meet my needs? Ever thought about a family emergency? Would m...

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...

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...

Road Trip Refueling a BMW i3 REx

Image
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 w...
