I have one question about my batery. I buy Peugeot Ion 2012 with almost 60 000 km. I still wait for obdlink mx for better diagnostic. But I make test today. If i connect chademo quick charger he told me start capacity 18%. Charger disconect at 82% and give me 7,5kWh. I worry about battery. Fully charged range is about 80-90 km without A/C or heating.
Looks unbalanced, try by completing the charge at home with slow charge for whole night. Charge shouldn't ever be manually stopped right after reaching 100%, because after charging, the balancing begins. Not leaving in charge after 100% for many times can lead to cells unbalancing, which results in apparent total capacity reduction.
