Just got word this morning that CFIUS approval for the deal with A123 has been granted to Wanxiang. Still a couple details to take care of, but I...
I think you transposed some numbers here. The C rate is .1875, not .8175. Big difference. You could simplify your math to get to the same answer:...
Hi Ron, It will be perhaps another week or two before anyone is ready to get into defining details of a potential service program for Hymotion....
Hi again, Sorry to hear about your job and the lack of success with the pack. At this point, it seems most likely to me that you have some cells...
I'm very happy to hear that the technique worked for you! This probably means you have a cell group with a bit of a self-discharge issue. To keep...
Ah, ritual sacrifice followed by a gory post-mortem....you'll get better results if you paint pentagrams around the lab and drip the blood of a...
I see two possibilities here--balance load resistance is constant, and duty cycle is 100%, which would mean current moves with Voltage in a more...
If by "go soft" you mean they become limp and flexible, then neither of these is true for A123 cells. I don't think there's much of a vaccuum...
It's not so much that there's a need to "hit it hard", but when you get into the higher Voltage range, the speed at which you got there is...
Agreed on all counts. Interesting storage scheme. If you look at the website for the Rimac Concept One (my favorite electric supercar at the...
Are these pouch cells or cylindrical cells? If they're pouches, are they compressed in the Enginer setup? Either way, my understanding is that...
Wow. It's hard for me to imagine anyone tolerating a balancing system that seems to work as poorly (or not at all) as I hear about from the...
Well, your first mistake was listening to AC/DC in an electric car. Each side of the electronics system tends to cop an attitude, and they end up...
Actually, you may be within the margin of error depending on how you arrived at your 1/2 kWh number. 6.6Ah * 3.0 V=19.8Wh. Cell 11 having this...
I strongly recommend finding a low impedance path to connect to cell group (CG) 11 in the Realforce pack. Current flowing in your sense lines...
The rust made me uncomfortable as well. The kluged-up harness isn't giving me any warm fuzzies either. Lots of opportunities for problems. Would...
The bit of extra capacity trick should work, but of course there are limits to how bad the problem can get before it makes more sense to just...
Dan, I'm glad to help advance the cause and I appreciate the dialogue. 3 years ago I would have been right there trying this stuff with you if I...
The more I hear about Enginer, the less I like the system. Seems like a lot of fumbling around in the dark. It's fine to develop a system that...
What would be the mechanism causing such a loss of accuracy? This would surprise me, unless the design of the electronics is extraordinarily bad.
