SLUUCO9A April 2023 – November 2023 BQ28Z620
The device can detect cell overvoltage in batteries and protect cells from damage by preventing further charging.
The protection detection threshold may be influenced by the temperature settings of the advanced charging algorithm and the measured temperature.
