After the learning cycle completes, update status is 0x0e,Before saving the Golden File, set Update Status to 02,Qmax Cycle Count to 0, and set the Cycle Count to 0.

use new golden file for a battery pack,update status is 0x06,Do I need to modify it to 0x0e?How can I change update status to 0x0e?

thanks

    Hi

       To make update status 0x0e, you have to have Qmax updated with a battery with its update status being 6. For example, discharge the battery with more than 37% with the start and end point out of the flat region of the OCV curve.

       Make sure the battery is fully relaxed before discharging.
