Some one has already mentioned climate but I if a car has done a short distance but sat on the drive way at 100% for most of its life, is a big degradation factor. Also the 30 kWh battery was a bit of a disaster. Interesting video. Thanks.
Number of QC and Battery heat cycles is probably a bigger factor than age and km. Interresing formula, but think it is not accurat without QC numbers into it. Have you tried to see how the math works out if you take the number of charges and the number of QC into the equation? Is the leafspy SOH calculated, or is it the BMS that is measuring it?
Thanks for the info. I should have said my formula is for the 30kWh battery. The 2015, 24kWh is known to be more robust and I’m not surprised yours is higher SOH. I think 2015 was the pinnacle of battery chemistry for the Leaf.
@@GreenwayElectric Hello. My Leaf also 2015 & 146K has already done. your formula gave me around 65% SOH & actual is 80.53% based on the leafspy report. I'm Living in Finland. cold climate.

Would be interesting perhaps comparing to 24kwh models too given different data
I agree. I think the 24kwh battery has a very different degradation curve and therefore would result in a different formula.
I wonder if they were all used in the same are, experiencing the same climate?

hello...my car is late 2015 with 86,313km , your formula give me estimate a 74.36%...and real is 81.82%....

@@GreenwayElectric happy to know that...
Very interesting, I can get you Data on 2 x 24kwh if you are interested
