Re: 2018 Leaf: How to Charge to 80% Only?

I saw on youtube lately that one guy was test driving the 2018 Leaf from 100% to 0% on a road test. He got the Leaf Spy connected as well. What he found was interesting. At 100% full charge, Leaf Spy showing 38KWh, there is a 2 KWh reserved room for regen. Nissan apparently never charge the battery to full capacity. May be that is why they said 80% option is not needed.

Also interesting is that at 0% dash indication, Leaf Spy still read about 9% power left. Looks like Nissan already designed the charging unit to prolong the battery life under normal use.


Nissan has always done this, although it used to be about 95% actual SOC at 100% indicated SOC. The batteries still degraded. Let's hope that 91% actual SOC is low enough. If I get one of these Crap-Tastic cars I'll be stopping at roughly 80%.


It was actually between 97.3 - 97.7% so 2.3 - 2.7 from full. 90% is 3-4X difference.

Realize the lower the SOC, the better. The cooler the better. Temperature is going to be whatever its going to be. SOC we can control. Nissan has given us no easy options but its still doable. I did it with 110 miles of range. With 160 miles of range, it should be a piece of cake.

Hey guys, I'm new to the electric car world. I got myself a 2018 Leaf and I'm learning little by little about the eletric world. That being said, I'm reading contradictions regarding "full charge" and "partial charge". Some say it's ideal to charge only up to 80% and others says I need to charge it to 100% so that the cells get balanced.... ? I drive my car daily and I use between 11 to 15% of it daily.

what shoud I do? charge it to 80 or charge it to full?

:?: :?: :?: :cry:

@DrKemLey you want to do both :-)

Basically, try to charge to 80% ish most of the time, but do charge to 100% once a week or so. And don't obsess over this...

However, be mindful that charging to 100% on a hot day is not good for the battery, nor is charging to 100%, then letting the car sit idle for hours.

I charge for an hour when the car is below 60%. Before longer trips, usually about twice a month or so, I charge to 100%. Try to time for before departure an hour or so.

Should have the battery between 80% and 50% most of the time.
