AEK-POW_BMS63EN communication timeout led turning on only for fraction of second.

Hi, 

To emulate the behavior of cell added in AEK-POW-BMS63EN board, we used voltage divider circuit (36 V, 10 5ohm resistor)and used the voltage drop of each resistor as input to C0......C14. 

For some days comm. timeout led was being turn on for 60 seconds whenever power on the supply, and work correctly to get voltage, current, temperature measurement and also balancing was working. 

But once balancing was turn on (due to voltage divider circuit voltage and current will increase for every i/p c0...c14) after that whenevr we power on supply, comm. timeout led was only glowing for very short duration, and now now no voltage or current measurement is possible as it just timeout before any communication.

Is there any way to make its timout time for 60 seconds as it was.

or Is the IC got damaged due to cell emulated ciruit. ?

 

Thanks and regards,

bitBuddy
