Tool/software:
Dear Sir,
We have designed a BMS system with a 6s configuration with COV parameters set to 4.2V/cell and CUV set to 2.5V/cell. We have installed a BMS inside the battery pack and flashed our BMS as ,it was programmed successfully. After programming, it was showing successfully 25.20V but then I kept BMS aside for 2 days hoping it was working fine.Later, when I saw BMS it was not showing voltage and it was showing communication error. After that, I opened the battery pack and check BMS board was fine but my individual cell voltage dropped to 5mV and some cells to 1V. I don't know how these issue has happen, and what will be the possible cause of these issues are. Is there any parameters changes in srec file required to overcome these issue? or What causing these battery to get deeply discharged?
Waiting for your reply,
Shubham
