But wouldn't the battery warm up during the charge and then be warmest after 80% clear up to 100%? I do have a level two EVSE and it's rated at 7kW, which is plenty for the 6.6kW onboard charger. Wouldn't that warm the battery before it got near 100%?
I mean my last job from my house is only a mile or two away, and it's also my longest job, about 6 hours. Plus the maximum speed limit between the job and my home is 35mph. It would seem it would get more heat from charging at home than from the drive home.
Before my last job I have several others here and there. Which means short drives here and there, in a town with a maximum speed limit of 35mph. I have reached the low battery warning a few times. But my schedule changes so much I never know how far I'll drive in a day. If I think I might run out I go charge for an hour during lunch. Or even take a coffee brake and charge up for 15 or 30 minutes. I'm glad I got a 6.6kW charger!
It just seems that most days I could have made the whole day off of 100% charge, or even a day or two where I have to head 30 miles out of town and then 30 miles back first thing in the morning, at which point I have to charge getting back and things get a little sketchy if I didn't charge up 100% the night before. It also seems that if it's a day where I charged to 80% and now it's looking like I need to charge during lunch that's the day my wife wants to go eat at a restaurant that's nowhere near the home or the town's public charging station.
It just would make things a bit easier if I could charge to 100% every night and not fear it's hurting the battery.
Definitely charge to 100% then
If you have 6.6kWh charger and you do very short trips during the whole day it might be true that charging from low to full will raise temperature more than during the day. Doesn't really matter. If you let the battery sit it will cool down. So charge whenever you can. At those low temperatures battery hardly degrades. Literally, less than 2% per year.
I have DC stations everywhere so I can't run out of charge. If I wouldn't have them I would always charge to 100% in winter just to be more prepared.
Nissan did not drop 80% option in EU. Therefore it is definitely EPA thingy.
