BQ76940: BQ76940

Part Number: BQ76940


I'm working with a custom battery pack (54.6v (13 cells), 20A), manufactured by a Chinese company. They designed the battery management system using BQ7694003DBT from TI.

An issue exists with this BMS, and when I connect a load (for example, a 5A load), the voltage drops to zero and then rises back to its maximum value and works properly.

I was wondering if you could assist me in identifying the problem. I was thinking there may be a problem with the BQ7694003DBT circuit.

Here I attached the monitoring with and without adding a 100uf capacitor to the output line.
