Weak cells and what is big difference in mV?

Sat Feb 10, 2018 6:33 am

Hi,
Its my first time i have ran the car into turtle mode. So i pluged LeafSpy just to see how it looks in there. It turned out that LeafSpy is showing 5 "week cells". What on earth that means? Same as "bad cells"? And cell ballance difference was huge and near 300 mark. Should i be worried and go to dealers or is it normal stuff when you pass VLBW?

4% SOC its rather normal to see at least "some" weak cells. Actually, I should say its not extremely unusual to see. My average delta with 50% SOC or higher was in the 7 to 35 mV range but that balloons to 250-350 mV range when SOC is in single digits.
