Hi
We designed a supercapacitor pack charging board using the BQ25756 chip. The power input is 24V/4A. The capacitors used are 2.7V/30F, with 10 capacitors connected in series. The charging board outputs 27V and the charging current is set to 3A. After configuration via I2C, it can output normally. However, there are status errors during the charging process. We captured several waveforms of the voltage across the capacitors and the charging current during the charging process. As follows：
This is different from the capacitor charging waveform of the EVM reference board.
Are there any ready-made solutions or tutorials that can be referred to?
thank.
