BQ79731-Q1: BQ79718EVM-049 reading cell voltages less than 18 cells using power supply.

Part Number: BQ79731-Q1

Tool/software:

Hello, this is JJ

I am wondering how to read 14 cell voltages, not 18 cell voltages using power supply with BQ79718EVM-049.

1 - 13 cell voltages are good, but the 14th cell voltage is dropped with 42 V power supply.

1 - 13 voltages are about 3V, but the 14th cell voltage is about 2.6V

I already changed the register DEV_CONF2 (0x003) to 0x8 (14 cells).

How to fix the EVM to read the 14th cell voltage well?

Best regards,

JJ
