BMW's ChargeForward Initiative Seeks Participants

Image
Do you live in the San Francisco Bay Area and drive a BMW i3, i8, X540e, 330e or 740e? If so, would you like to get paid to participate in BMW i's award winning ChargeForward initiative, while helping to shape the future of electric vehicle charging? BMW is seeking 250 individuals to participate in the second phase of the ChargeForward initiative, which will last approximately 24 months. The first phase of the program is now complete, and volunteers are needed for the second phase, which begins in January, 2017. This phase includes vehicle to grid managed charging, and stationary energy storage systems which utilize repurposed MINI-E battery packs. Back in 2015, this program won the ESNA Innovation Award for EV Battery 2nd Life Energy Storage System. From the ChargeForward website: The second phase of ChargeForward, from January 2017 through December 2018, is expected to demonstrate expanded benefits of charging optimization through management of both current and projected future c...

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, ...

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...
