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.

For those just charging with 120v standard plug...I really recommend using a smart outlet. Make sure to get one rated for 15 amps. But it is much easier to set timers and a schedule on your phone than the controls in the car.

Yep on the Tesla Model 3. The charge limit can be chosen in the car or by phone app. Very convenient.

Nissan *could* of course do something similar. They are keeping their R&D to an absolute minimum.

Hi, i was reading this topic, and i decide to do a quick english language selection option in an app that i've created. Originally, could only work in portuguese.

In a short description, the app allows to calculate how much time do you have to charge to get desired SOC, depending of several variables that influences the charge, like current, voltage, etc.

This app is in development, i am actually doing a big change in the layout and bringing new funcionalities. I bellieve that this new version will be available middle October. Until then, please use as it is: https://goo.gl/itaZr6

Similar to some of the posts in this thread, I also have a JuiceBox Pro 40 and it works great for charging to a specific percentage like 80%. I enter in the amount of charge left on the car when I plug in and can set the iphone app to charge to whatever percentage I set it to. I have a Leaf S but the Juicebox gives me some remote charging functionality of the SV/SL.
