I have a query need your help.

The first round of learning cycle is normal. After the Update Status is 0X06, during the next round of learning cycle, the Update Status is updated to 0X0E during the resting period after charging, does not finish the second learning cycle. Does it normal?

Attached the log file for your reference.

Hello Star,

Can you clarify the issue? this looks like normal behavior, LStatus goes to 0x0E after the charging period completes and an OCV is taken. Going from 0x06 to 0x0E just indicates another Qmax has occurred.

Sincerely,

Wyatt Keller

Hi Wyatt

Thanks for your reply.

However Qmax count is still 1 when updating 0x0e, and Qmax not update. It must full discharged and rest about 5 hours then the Qmax count is updated to 2.

Does it normal?

Thanks

Hello Star,

The Qmax count is part of the lifetime data which only updates every 10 hours, it will not update at the exact moment of the Qmax event.
