If your Leaf is 2014 or newer. Charge-nissan-leaf-to-80?
Sorry to say that is a totally non-technical article, making statements and claims without test data or proof or footnotes does not make it true--its just this guys opinion and garbage to me.If your Leaf is 2014 or newer. Charge-nissan-leaf-to-80?

This paper came with this person's US '22 Leaf (see bottom 1/3 or so). We've gotten confirmation like atIt does raise the question as to why Nissan did away with that capability. I'm a new Leaf owner and have gone over the owner's manual and also watched the You Tube Nissan Channel Videos. I have not come across anything that says only charge to 80%. Can someone refer me to a Nissan publication that recommends this? Thanks

Factors that will affect and may hasten the rate of capacity loss include, but are --
-Sustained high battery temperatures (caused for example, by exposure to very high ambient temperature highway driving with multiple quick charges)
-Sustained high battery state of charge (caused,
for example, by frequently charging to 100% state of charge [and] leaving the battery above 80% state
of charge for long periods of time)
-Higher than estimated annual mileage accumulation (such as more than 12,500 miles per year)
There are various govt averages. These (for example) cite some averages for the US:Interesting document, extracted statement on capacity loss:
Estimated annual mileage--huh? whose estimate?
12,500 miles is 50 miles a day for 50 weeks (commute for work) with no extra allowed for weekends or 2 weeks of vacation.
ChargePoint app can show you kWh delivered on a phone or watch. Not what you asked for, but you can check remotely. Requires setting a reminder, checking, snoozing reminder while awake and then unplugging.The lack of an 80% charge limiter is one of my biggest frustrations with my 2019 SL. (the other beginning CHAdeMO, I'm unlikely to ever do another road trip after my first experience) Especially since it seems like a charge limiter should be an easy software update. I purchased the car early this year, taking advantage of the $4,000 US used EV tax credit on top of the higher depreciation of EVS over ICE. The car was an excellent value, I love the tech, the comfort and it meets 98% of my driving needs. I will likely keep this car for another 5 to 7 years and want to maximize battery health, hence limiting it to under an 80% max charge.
I live in a condo and don't have the option of a personal charger. My complex has a shared power ChargePoint level 2 charger that I use a couple of times a week to keep my Leaf between 30%-80% SoC. The charger delivers 6 kW unless a second car plugs in, then it delivers 3 kW. So calculating charge times with a timer is ineffective. It's frustrating, I should be able to set the car to charge to a certain percentage, have it stop charging then it or the charger app notifies that the charge is finished. This really doesn't seem so much to ask, as every other EV I'm aware of has a charge limit feature to help maximize the battery life.
First time I've seen this. It obviously shortens the time to get to 160 000 km warranty limit, but how does it impact capacity? How does milage matter if I only ever charge up to 80% on L2 and keep the battery cool?Higher than estimated annual mileage accumulation (such as more than 12,500 miles per year)
That's exactly what I do Currently, a combination of the ChargePoint app, the Nissan EV services app, and a spreadsheet I built, that I can plug in the current SoC. But charging an EV should not require this much thought and monitoring. With the state of technology, it should be as simple as setting up the charge once, then plugging the car in. Not having a charge limiter is an unnecessary complication to the ownership experience of a Leaf.ChargePoint app can show you kWh delivered on a phone or watch.

Unfortunately OVMS doesn't support 2018+ models, otherwise you could build a SoC monitoring script and for some model years send command to stop charging.
https://mynissanleaf.com/threads/2013-battery-bars-half-way.31297/ lost half their capacity bars on their 1/2013 built '13 Leaf in the super mild climate of city of SF, so you can't blame temps or lack of thermal management. Google for san francisco average temperatures.Unless you are putting many thousands of miles on the car each year (in which case you probably shouldn't be driving a Leaf in the first place), I just don't see this as being a real problem. I charge mine until the Chargepoint app tells me it is no longer charging at the full 6.4 amps, and then I take it off. I have no idea what SOC this is - nor do I care. After 5 years, LeafSpy tells me I have an SOH of 90, so I don't see any indication of undue wear on the battery. After charging, the GOM tells me I have between 200 and 250 miles of range (I don't know why it differs so much, but I don't really care, either) so it appears I am getting everything out that it has to offer, and since I have not spent a dime on the car since I bought it new, I am a happy camper!
