I'm trying to revive Fiat 500e EV battery which is discharged after not using it for 3 months (second reason was bad 12V battery).
I've disassembled whole battery pack below car and I have access to each of 18 individual battery module inside (each battery module has 5 or 6 battery cells). There are Li-Ion batteries (Samsung SDI cells). I want to charge each of them individually. I'm wondering should I charge each cell individually or each battery module? Charged cells should be around 3,6-3,7V and I think I should charge them separately. Can someone confirm? What voltage and current should I use? "standard" 4.2V is fine and what current?
