Hi,
I went to Nissan dealer today for a drive of a 2019, 90000km, 87% soh Nissan leaf.
I used leafspy during my drive.
When I arrived, it was connected to chademo (dc) and car was displaying that charge was at 6kw. First thing I find strange. Sales person couldn't give me any answer. Photo enclosed. Soc was 80%. Battery temp around 40°C and outside temperature close to 0°C. Could that be issue of the car or some limitations set up in charging stations? (Sales guy could not tell me).
Then during my drive test, I checked battery cells. Right after unplugging it, cells seems to be quite balanced with low cells voltage difference.
While driving normally, cells voltage difference remained below 50mv. But when accelerating stronger, difference went up to around 70mv...so I took it to highway and accelerated foot to the floor, several times. Cell voltage difference went up to 115mv. Also cell 1 dropped to around 3.4v. but maybe this is in the norm?
This MV differences were only during acceleration, when cruising, it was balanced.
Is it normal behavior during strong acceleration in winter? Any risk that some weak cell could prevent me from using the car in the next few years? I plan to keep it at least 3 years with maximum 60kms of drive per day, no highway or really not often.
Thanks
