2021 Nissan Leaf 40kWh battery status

Quick video about how to find battery status on a Nissan Leaf.
How long it takes for the battery to lose some of it's capacity depends on how well it's treated, or not. How heavy your right foot is, how many and how fast your charges are while hot/cold and probably whether the factory worker had a bad day or not.

Hi peter thanks for the video, for the longest i wanted to find how to see the battery life on the 2nd gen leafs. I thought it was that but could not confirm it. Your vid did it, thanks man!!

Thanks for the feedback. Good to know they're of use.

Thanks for the feedback. Always nice to know they help.

This status shown in the car isn't much use.
Its divided into 12 bars, and the first dissapeares only after the battery has lost 15% capasity. (After that its 6,5% per bar).
So the only thing you can read from this video is that this car has somewhere between 85% to 100% left.
To do a more exact mesuresment you need a odb 'dongle' to plug into the car and do some readings on an app ('leaf spy').

The first 8% is lost in the first 1 year, irrespective of how the car is used. So anyways the battery capacity should be counted from 92% onwards. Which is why the calibration of each segment is marked in this way. So a 40Kwh leaf is in reality a 36 Kwh leaf since almost new. Many other car brands like Hyundai, Kia, use an initial buffer so you dont notice the initial 8% drop but in reality they have a slightly bigger battery than specified in the datasheet.

@@aneeshzutshi3419 they typically loose more the first year, but it varies between car types and batteries, and 8% is a way to high estimate. (Teslas are typically 4% first year and 0,5% per year the following years).
On the leaf's it actually seems to be pretty linear- as in that the bar no 2 is lost faster than the first (in a rate of approx 6.5/15).
My 2012 Leaf (1st gen leafs from 2012-2012 have poor batteries) lost the first bar after 5yrs3mnts (15%) - so nearly 3% per year. Nextbar (6.5%) was lost after 2yrs3mnts, and the one after that 2yrs5mnts - so nearly exact the same rate at nearly 3% per year. This pattern is the same for all 1st gen leafs in Norway (there are a lot of them here...).
New Leafs (2018- ) are way better though - loss approx 1% per year - no initial 8% loss.

@@erik5820 I am basing my claim on leafspy data from hundreds of Leaf 40 cars and reported by users across multiple forums. The SOH in leafspy reaches close to 92% practically by the end of the first year, and from then on goes down very slowly. TH-cam does not allow me to post links but I will try to post them in subsequent comments.

Please check the battery degradation chart prepared by Hiroshi based on numerous leafspy data. If my posted link is not visible search on youtube this video "Battery degradation, Cell balance of 2018 NISSAN LEAF at 180,000 km and SOH prediction at 400,000km" by EV164 HIROSHI. The chart shows SOH drop by year and Kms travelled, and by the end of the first year its at 92.5%. My own leaf is closely following that pattern. This is about leaf 40, the older chemistries were much worse. Most other car companies use ways to hide this initial degradation, but the free lithium ions need to stick to anode and cathode in the initial months to reach an equilibrium hence the initial sharp drop.
