Hi all
My brother has a gen 2 leaf tekna with 18000 miles on the clock. He has owned it since it was a year old and 6000 miles.
He does little miles per week, generlly charging of a granny charger as it has lower current draw to enable him to top up off his solar production.
I did recommend to him a few months ago to start charging fully thro the summer whislt he is producing good solar power to get the cells to balance, as previously he would end the charge early.
I own a E-NV200 and always charge to full, use mine every day travelling about 50 miles per day.
A few eeks ago he noticed an odity. going from his house to mine, over a mountain, he lost loads of SOC going up and and gained a load coming down. When i go to his house, generally i loose 25% going up same mountain, and regain 3% coming down, its about a 10 mile mountain trip top to bottom.
That was odd compared to mine, I plugged in my leafspy and it shows 1 cell 60mv lower than the rest, CELL 49.
The odd thing was that the BMS was actively working, showing draining on all cells including cell 49, and cell 50 was taking energy, the cell next to the rogue one.
I would have thought that all cells would have been draining into the weak one.
Anyhow, i`ll upload the leafsy pic for you to see, and any thoughts / suggestions would be greatly appreciated.
Thanks.
Anthony.
