I'm sure it has been mentioned before, but I found this interesting plot at flip the fleet:
Benchmark your Leaf before buying! - FlipTheFleet The figures are updated to the beginning of June 2020 so are up to date. Interesting to note that the best 2017 30 kWh cars are doing slightly worse that the best 2016 year models (91% vs 92%), the worst 2017 cars are at 78% already vs 79% for the 2016 cars. I wonder what happened in 2017? Also, given that the guarantee covers you for degradation below 9 bars in 8 years which should occur at around 66% (12th bar = 15% and 11, 10,9 are each 6.25%) I think most of us are still going to be above that, given that the degradation seems to be large to start with, then slows down. 3.5% a year, which is what mine is averaging, would only get down to 72%
The figures show that the 50th percentile SOH for a 2016 30 kWh Leaf is actually around 86%. So although I've been panicking (and definitely think the range has dropped off slightly more than it should) my car at 87% and Barfly's at 87.8% are both slightly above the average. Mr Roboto at 89.15% is actually 3% above the average. the total range between the 5th percentile and the 95th percentile is from 79%-92%.
That's not to say that someone hasn't got a failing cell that messes things up at lower charge levels.
I think one of the problems is that someone always pops up with something along the lines of '
My 2014 Leaf has done 120000 miles and is still at 95% SOH'. This inevitably causes panic in those of us with lower figures, wondering what we are doing wrong, when our figures are actually normal.
Looking forward to seeing Mr Roboto's figures at a low state of charge
