The Battery Management System (BMS) has a crucial role to play in making battery use safe, reliable and cost-effective. The Battery Management System (BMS) has to integrate something called cell balancing which is the most crucial feature in dealing with cell unbalance. This paper explains, method for calculating the individual cell voltage of a Li-ion battery pack and performing cell balancing which usually involves bypassing certain cells during charging (and often during discharging) by attaching external discharge resistors parallel to the cells by regulating the corresponding FETs. The standard current for by-pass varies from a few milliamps to amperes which is depending upon the selection of discharge resistor.
