2018 Leaf: How to Charge to 80% Only?

Tue Feb 20, 2018 10:48 pm

On the old Leaf, you could program it to charge to 80% charge only to decrease the wear on the batteries. However, on the new Leaf, I do not see anywhere on the manual how to do so. I only see an option to program the start and end times for charging. Is there an optional program to charge only to 80% full capacity? If so, how do I do so? Thanks.

no.

your only option is manual manipulation of the charge timer every day

The elimination of the 80% charge option in 2014 left a bad taste in a lot of our mouths. Not only does Nissan not admit that they did it because the EPA range estimate got averaged in 2013, they have doubled down by insisting that there is no need at all to limit charging to less than 100%. This despite everything that is known about lithium batteries suggesting otherwise. If it's any consolation, the actual state of charge (SOC) at 100% indicated is more like 96%.

There IS a wireless, app-controlled timer that plugs in right between the J-1772 plug and the car's charging port, but it isn't rated for outdoor use. If you have your charging station in a garage, that is your best option.

How far do you drive every day? There is nothing wrong with charging to 100%, as long as you don't leave it sitting at 100% for extended periods (especially in warmer climates). If your initial daily drive is enough to get it down around 80%, then just let it charge every night. Use the timer so it finishes just before you are ready to depart.

There actually IS something wrong with charging to 100% if you don't need that much range. No other EV does that by default. In warmer climates, any time at high SOC and moderate temperatures is not good.

I have to admit I agree; I charge to 80% almost every day.
I can't believe Nissan never "restored" the ability to do this...or (better yet) made it programmable (variable %).

Agreed. Incredibly stupid. My first full charge indicated DoD of 92% which I thought was great but not to be. My 2nd charge went to 506 GIDs an increase of 15!

I think GM’s solution here was brilliant. They made an 87% charge option by labeling it “hilltop reserve” implying it’s to leave space for regen if you live at the top of a giant hill. This keeps the EPA out of it and they get the full 100% SOC range on the Monroney.

I hope Nissan will do something similar in the future

Yes, all Nissan had to do was call it "Max Regen" or something like that and they'd be fine. They just don't want to admit to being wrong.

I believe the Tesla Model S's have an option where you can choose any SOC you want(within a range) do they still have that option and does the Model 3 have it? If so and Tesla can get away with it, why can't Nissan do something similar :?
