Loss of regen occurs mostly when the temps get below 80F, more so below 50F, and very much so below 30F (probably not something that you're used to seeing). ;)

WOW, that's got to be the explanation!!

On a related note, the "very much so below 30F," back in 1989 I had just recently moved down to Florida, it was December 23rd, 24th, and 25th, when it got down to a "record setting 32 degrees" according to The Ledger for the 23rd, then down to 21 degrees on the 24th. There were rolling blackouts on Christmas Eve, as people refused to turn off their Christmas lights, and the people talked about it for a quarter century. Coming from up North, of course it was nothing, but it really devastated a lot of people down here, especially in the citrus industry, which Polk County is know for. And yes, now I'm one of those people shivering uncontrollably at 40 degrees if I don't have a winter coat on. :oops:

The amount of regen available is also speed dependent, with the most amount of regen available around 10-15 mph. Below and above that speed the amount of regen tapers off.

Definitely on '11-12 LEAFs with 2+ bars lost, the amount of regen lost is significant. It takes very careful driving to maximize efficiency where one used to get away with regen recapturing energy when slowing down.

4 bars down I only get about 1/3rd the amount of regen slowing from 45 mph to a stop than I did when the car was new. At freeway speeds I almost never get a full 30 kW of regen any more. With 50%+ SOC I only get about 15 kW of regen.

You really have to drive carefully to get high efficiency numbers now, it used to be easy when regen was normal.

Your car is in the wiki for the 1st bar lost. Give me miles and dates for bars 2, 3, 4 and I'll add those and the 5th you just lost.


I finally got back to reviewing my LeafSpy logs and below is my bar loss info if you can add it to the wiki.

I lost my 7th bar this weekend. I suspect that by the end of summer, I'll have to replace the pack.

The worst I know of is a 9 bar loser which I posted at viewtopic.php?p=513873#p513873.

'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)
'06 Prius

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

I do now. Thanks! I was really excited at first, but as I looked into it, it looks like those will be about 80% capacity packs. I made a comment over there, but my math says the cost per year should be about the same for my use and I may as well enjoy the higher capacity of a new pack for a few years.

The quotes of actual news say greater than 80%, meaning that will be the minimum. Will it be noticeably more than the minimum or not? I don't know. But I'll keep my eyes and ears open for later developments. Pricing can change.
