Hello everyone,
I have recently (early December 2019) bough a 2nd hand LEAF30 Tekna, approaching 3 years old (17 plate). I bought this car from a Nissan dealer and was given a report showing 5/5 stars for the various battery health conditions - yes, I know this isn't really worth much! The car had done very low mileage for its age, at around 7500 miles. I have since put another 1300 or so on the car. Before I purchased it it was untaxed for a good few months so I suspect it was sat unused somewhere.
I have only recently got hold of a dongle and the Leafspy app (I know I should have done this before buying the car but I didn't). Anyway, I was curious to see the battery SOH and number of charges etc.
I was very happy to see the SOH reported as 98.2% but a little confused as the HX value is 88.11%. Browsing the many threads online regarding battery health I've never seen anyone with these two numbers so far apart.
As you can also see the car has only had 9 quick charges, 5 of which I have done since I bought it. My first few drives of the car showed the last 40% of the battery disappearing extremely quickly (judging by the dash SOC display) but since I have done a few charge / discharge cycles this is much improved and the BMS seems to estimate much better. I suspect the car has been rarely used and given lots of smaller top up charges rather than using for longer range driving.
I have no complaints about the range, I am still getting used to driving more economically but have managed 80 miles from 100% to LBW even in the cold wet weather since I bought it.
I would appreciate any comments on the Leafspy screenshot below - there are lots of very knowledgeable people on here by the looks of it and I am although I have an electronics background I am completely new to EVs.
Thank you.
