Incorrect State Of Charge Readings Causing Problems For i3 Owners

Image
With the i3 REx, Reduced Power can occur if the operator continues to use more energy than the REx engine can produce. Examples of this would be continued high speed (over 70 mph) driving or long, sustained hill climbing. However this new problem that has plagued some i3 owners isn't caused by over-taxing the REx.  Someone once said, "You could always tell the pioneers by the arrows in their back."  A recent software bug has cropped up that seems to be affecting many of the early build and higher mileage i3s that are mostly driven by the early adopters. The problem causes the car to go into reduced power mode, or in some cases shut down without warning when the display shows about 5% - 6% battery remaining. In mid 2016, BMW released a software update, (version 16-07-501) that was supposed to correct the issue, but for some unknown reason it didn't work on all of the vehicles. They then sent out letters to the early buyers to inform that they need a software update. Re...

The 2014 (60Ah) i3 REx vs The 2017 (94Ah) i3 REx

Image
255 miles of combined range? This range estimator is probable a little more optimistic than real life, but I definitely believe 200 miles is possible with the new 2017 i3 REx.  What a difference three years makes.  I was able to secure one of the first 2017 BMW i3 REx cars that made its way into US dealer inventory, compliments of Chris Chang, Sales Manager at BMW of Bloomfield here in New Jersey. The vehicle is mostly the same as my 2014 i3 REx, the one big exception is it has the new 94 Ah battery cells, which increase the overall battery capacity from 21.6 kWh to 33 kWh without increasing its physical size. That was necessary, since this isn't a redesigned i3, so the battery modules had to fit in the existing battery tray. The 2017 i3 REx in Fluid Black next to my "Moloughney Red" wrapped 2014 i3 REx As much as I wanted to check out the moonroof option that this car had (finally the moonroof is available in the US!), there is no denying the single most important improv...

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...

Q&A with BMW's Jose Guerrero at the New York Auto Show

Image
Jose explaining the features of the concept i3 at the BMW i Born Electric Tour back in 2012 Having been in BMW's trial lease e-mobility program for five years, I've been able to get to know many of the program managers and engineers working at BMW i in North America. Jose Guerrero, P roduct Planning and Strategy Manager for BMW i, is one of only a few people at BMW of North America who has been a constant force in the program over the years. That's the nature of the auto industry though. People move around within the company, and often even leave to take on positions at competing OEMs. So when I saw Jose's name on the list for available interviews at this year's New York Auto Show, I quickly reserved a half hour to sit down with him and talk about the i3 and the future of BMW i. My i3's battery pack. It was removed from the car in less than an hour. Future Battery Replacement The first question was easy. There has been a lot of talk about recent comments by BMW...

462 Mile REx Road Trip: New Jersey to Vermont

Image
We stopped at the Big Moose Deli in New York for some coffee. It's about ten miles from the Vermont border.  Perhaps the most discussed topic of the BMW i3 is the implementation of the range extender for the North American market. In an effort to have the vehicle qualify for the California Air Resource Board BMW set restrictions on how and when the range extender can turn on, effectively reducing the utility of the REx. These restrictions are most apparent when attempting to use the car for long journeys which include drastic increases in elevation. This topic has been covered here and on every other EV site extensively, and recently it was announced that BMW is working on a software update that will allow, under certain conditions,  the range extender to come on much earlier than the 6.5% threshold it currently uses. I am actually beta testing that software for BMW now, having had it installed on my i3 just last week. The new software also includes some other updates that wil...
