Smart.

As for wimpy,
Our 24 kWh LEAF has been stuck at '6 bars' on the temp gauge for at least a week now. I don't feel like finding out the actual temperature with LEAFspy :shock:

Tomorrow (Friday) it's expected to be in the high 90's in Ohio during my afternoon commute. Plan to watch Leafspy on my 40KWh during the return commute which is about 40 miles of continous expressway. Based on previous observations on 91-92* degree days, likely see 110 F battery temps with air temps in the high 90's. The thing I noticed is the pack does not shed heat after it's run hard. Pull a hill at 65-70 or aggressively pass a truck, it gets hot and stays there several hours. That can't be healthy. I'm too chicken to DCFC at those temps so won't see the spike like the graphic chart.
Not surprising... even if I leave my 24 kWh Leaf outside at night for many hours, it will only cool by a few degrees F (say 3 to 5 F) if outside air temp is much cooler than battery temp (e.g. OAT at 60 F or lower and batter temps at say 75 F).

I accidentally left my Leaf out last night and battery temps went from about 74 F at past midnight to about 64 or 65 F at ~8:15 am. IIRC, OATs got no lower than mid to high 50's.

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

Left the house @ 6:30 this morning, car was charging pre-dawn hours on 6.6KW and was to @ 90% SOC when unplugged to leave. Air temp was 78, was running late so didn’t mess with leafspy but noticed the temp gauge was still 1 click to the right of center so likely 95 F or slightly higher. Bet this will be toast this afternoon.

Might lose two or three days of battery life today, rather than just one.

And his battery will only last 15 years rather than 20 years.

You mean 10 - 15 years ... until range is ohh ... around 10 miles.

If it was a 2011, perhaps. Newer LEAF batteries are much better. You did know that, didn't you?

This turned out to be a non-event relative to the heat. This afternoon leaving work air temp was 96 F and dropped gradually to 90 by the time I got home an hour later. Leafspy showed battery temps 95-96 F to start, which gradually climbed over 30 minutes to a max of 102 F where it stabilized. Afterwards, ran some local errands and checked Leafspy again after 3 hours, battery temps dropped to 97 F.
