Why dose design resistance increase from 60mr (default settinf) to 1116mr?

Hi,

Design resistance is calculated on a per cycle basis during dsg. It will update to the nominal resistance seen by the gauge.

Can you tell me how to calculate the design resistance increase in the bq49z50r1?

Sorry, that's internal to the IT algorithm. It is TI proprietary and we can't reveal it.

The design resistance increases, triggering the CUVC protection, causing the product not to work normally. How should the design resistance increase be avoided?

Best Regargs.

Hi,

Design resistance is computed by the gauge. You cannot change it. You may want to disable CUVC if that is triggered.
