I'm retired English and live on the Cote d'Azur France. I bought my first EV a Leaf+ Tekna 62 kWh July 2020. My wife and I don't drive very much so we've only done 3000 kms in total. It has only been fast charged once to 100% when I took delivery. The rest of the time I charge it at home from a normal 230 volt socket. I usually keep it at 80% max and have once charged to 100% at home. I was curious about Leaf Spy so I bought a dongle and downloaded Leaf Spy Lite. I see my battery SOH says 91.8%. I'm wondering if this is normal.
Doesn't sound abnormal.

I bought my 62kWh Leaf in May 2021 and it is down to 92.7%. Decline was rapid for first 9 months, but has slowed dramatically since then. Batteries degrade with age, even if you don't drive much.

Re: The 62kWh Battery Topic

I suppose this is a bit tongue in cheek but I realise I didn't have any worries about SOH or even knew what it meant before I bought a Leaf Spy dongle. I think my best plan is to chuck the dongle in the draw, forget about it and just enjoy the car.

Sounds like your car was sitting around before being bought. When was the build date?

Re: The 62kWh Battery Topic

That is not a hot climate, so the 9% degradation in ~ 2 years is more than I expect.

Look for more shade
DO NOT park the car in a poorly ventilated, hot garage
Keep on LeafSpy monitoring once a year. Perhaps the first year was worse than now.

Re: The 62kWh Battery Topic

I've got an odd problem. My 22 Leaf SV+ has one weak cell. At full charge it is 70-75mv lower than the other cells. As I deplete the battery, the gap narrows. At 20% or less charge it is only 25mv low compared to the other cells. I've taken the battery down as low as 6-8% and then recharged it overnight. The cell sill persists in being lower by 70-75mv compared to the rest of the pack. I've done this more than a few times but but I can't get the cell to equalize. SOH is 97.93%, AH = 172.75. Has anyone else seen anything similar?

What is 'hot' for the battery? What is the max temperature in a garage before the battery suffers. July and August are hot months in the South of France.

Re: The 62kWh Battery Topic

What is Hot for the battery actually depends on another factor: whether or not the temperature drops enough at night to let the battery cool. 30C isn't really bad as a daytime high - unless the temperature stays in the twenties at night. A desert environment where it gets to 36 in the daytime but then drops well below 20 at night could actually be easier on the battery, as long as it gets exposed to the cool nighttime air.
