BQ77905: BQ7790500PWR

Part Number: BQ77905

Always fails to fill the full battery。

The device model I am using is BQ7790500PWR

I copied it from the technical manual in my demo.

My plan is to connect 12 series batteries.

There is no problem with the charging and discharging functions.

The voltage of the 12 batteries is also uniform and normal.

But the charging can only reach around 49V, and the charger stops working,

Three brands of chargers have been replaced, all of which are related to this issue.

The only difference in my DEMO is the use of 5 ping pong federation 0.002 ohm sampling resistors for sampling.

May I ask where the problem should I check?
