I suspect there wouldn't might not be an overheat problem but rather the cells will be taken beyond their design voltage, damaging them.RockyNv said:If you put full regen back into the battery when its at 99% or fully charged they you will likely overheat the battery so that it will fail more quickly. That of course would void the battery warranty since you are defeating the regen cutout that is there to protect the battery.
Only workaround for the OP is to not charge as fully.
:lol: All too true, but as you say, where is the sense of fun and adventure in such a simple solution.LeftieBiker said:Geez, where's the fun in that??! Why unplug an hour early when you can hack the car's primary systems, void the battery warranty, and risk who knows what else? Where's your sense of adventure, man?
I'd like to make regen work on my '12 even at SOCs not much above 70%. It's missing 2 bars and I have a feeling that's the primary culprit but missing 2 bars I really need the regen, but I get very little It's out of warranty so I don't really care about that so I would really like a way to bypass whatever is telling my car to only give one or two bubbles of regen even though the battery is much less than 100% SOC......Limey said:Has anybody found a way to modify the regen? Specifically, I am looking to make it so that it is available at 100% (5 dots) even if you are still @ 99% charge.

aarond12 said:It was odd to me that the Mitsubishi i-MiEV had full regen (running in "B" mode) even when the battery was full. I guess Mitsubishi realized that, on flat terrain, it takes more power to make the car go than can be regenerated. On a mountain, sure, that's not going to allow regen past 100% charge. It seems that Nissan is just being much more conservative than Mitsubishi was.
RockyNv said:At full regen you are stopping at full brake levels. Once the battery is fully charged to regen capacity the regenerative braking is reduced or completely turned off and only the friction brakes are used. Leaf drivers who live on high mountains have to be careful to not charge their cars fully when at home so that they will not loose regenerative braking on their way down mountain roads making it so they have to rely on friction brakes to keep speed down during their descent.
If you put full regen back into the battery when its at 99% or fully charged they you will likely overheat the battery so that it will fail more quickly. That of course would void the battery warranty since you are defeating the regen cutout that is there to protect the battery. The standard charging cycle is to taper off the charging rate the last few percentage points of the charge cycle since those last few percentage points of charge are the ones that can generate the most heat.
Really look before you leap on hacking the regen program on your Leaf unless the warranty is of no consequence to you.
