Re: Got a Leaf

It went to a dealer, so I don't know who'll get it. It had 29.000 km on it when I sold it, of which almost 20.000 km I put in.

Got a Leaf

I gave my C-Zero up for a 2012 Leaf which has only 20.000 km on it and battery at 94% State of Health. I just needed a bit more battery and a bit more driving pleasure on longer trips, which the Leaf does provide. I do miss the better regen of the C-Zero and it's city maneuverability, but I can't ke...

Re: CHAdeMO Questions

Yes. I just got mine back from the dealer after 3 weeks. Apparently quick charging then stepping on the accelerator too hard soon after can cause the RBS to fail and turtle mode to engage. I'm going to call BS on that. I suppose if you're in a hot climate the batteries could heat up while quick cha...

Re: Additional pack

Regarding the original BMS, you'd need to fake all the appropriate CAN signals to and from the rest of the car. So I wouldn't hold my breath on getting it to work. Balancing only happens at the very end of the charge as far as I know. Not during use. You could also try bottom balancing the second pa...

Re: Wrecked i-MiEV Battery Pack Discussion

Wow, nice, 92% charge. You got lucky that the pack is so full. Also means it's intact since if there was damage surely the SOC would have dropped and/or you would have cells at a lower voltage.

Re: Additional pack

I'd really like to have such a wreck at my disposal as well... Perhaps this should be moved to it's own topic though? Any admin see this?

Re: EVBatMon Readings

I'd just like to point out that ampacity means current carrying capability, not battery capacity. https://en.wikipedia.org/wiki/Ampacity

Re: 12v Battery - All You Ever Wanted To Know

JoeS, fully charged LiFePO4 cells will have a voltage of around 3.3-3.4 volts per cell after you leave them to rest. Thus around 13.3 for the four cells. The heater panel may show a little less than actual due to losses in wires, but it's close enough and the most important thing is that it reads th...

Re: 12v Battery - All You Ever Wanted To Know

JoeS, the one that I have doesn't have any BMS or other electronics in it or connected to it. It's just hand balanced once and that's it. You can open the plastic case to check voltages. If you don't have anything connected between the cells they won't get unbalanced by themselves, provided that the...
