I have a query need your help.

After learning cycle, the FCC updated and larger than design capacity.

but the SOH is only 99%. Why the SOH doesn't reach 100%? The design capacity is 4750mAh. After learning cycle is completed, Qmax has been updated and the FCC updated to 4850mAh.

Load selection 3

Load mode 1

Waiting for your reply.

Thanks

Hi Star,

How was the ChemID determined for this cell? Was the GPCCHEM tool used?

Can you please tell me if the SOH FCC max is the same as the Design Capacity?

Regards,

Anthony Baldino
