No Full Available Regen at 30%

Wed Dec 10, 2014 9:33 pm

I understand if the unit is mostly charged then regen is not available but it seems the last few months something is wonky. I could be down to 1/3 and still not have the last regen bubble available. I am thinking about putting it on video so back up my claim.

This is not really a big issue but an irritant. Has this ever happened to anyone else?

I haven't gone searching through the other posts, but I think there's a temperature aspect to the available regen capacity, and possibly the temperature dependence has been tweaked in recent updates. I've been seeing down to four temperature bars in the mornings, five during the days. Was your battery chilly when you observed the reduced regen?

I'm guessing you've got a 2012 LEAF with the P3227 software "update" (more like degrade) and it's cold outside.

NO REGEN FOR YOU.

It drives me nuts but there is nothing you can do.

Yes and Yes. Can you fill me in on why it does this? It is still under warranty and they should fix it if it is a mistake. It is only about 50F here though.

This update has been rolled out in conjunction with the retroactive battery capacity warranty introduced in 2013. The thinking is they wanted to reduce stressing the pack by limiting regen to reduce degradation and as a consequence reduce the number of warranty claims. No hope for a fix.

I was kind of wondering how much I stress the battery myself when I gun it. ( which I do often)

The good news about P3227 is that it also resolves incompatibility with some EVSEs, most notably the GE WattStation which is known to fry the onboard charger.

According to everything I've read, the problem is with the Leaf's software, not with the Wattstation. I have no problem with picking on GE, but in this case the blame appears to lie with Nissan.

No blame was implied, one way or another the end result would be the same, and if out of warranty would run you well into the 4 figures in repair costs.

This. I had only one regen circle yesterday until the battery warmed up over 6-8ºC or so. When driving mountains it is really annoying.

I still think it is a bug in P3227, as opposed to deliberate, but so far Nissan has refused to fix it.
