Is it possible to disable the OC (1st Tier) Chg and Dsg?

The customer requires that threshold is 20A and time is 5s.

Are there any good method?

Close any instance of bqEVSW open.Copy the attached file to the following location (or whichever directory you installed TI bqEVSW):

C:\Program Files\Texas Instruments\bq Evaluation Software

This will give you access to the OC (1st Tier) Chg Time and OC (1st Tier) Dsg Time DF locations. To disable the features, set these timers to 0.

Thank you for your support!

I could access OC(1st Tier) Chg and Dsg Time.

Please teach me Min and Max value of these items.

They are each 1-byte timers, so the min is 0s (disabled) and the max is 255s. The EVSW may limit it to a lower a value, like 240s.
