Battery Cell Balancing
The battery employs bypass circuit to maintain the balance between each battery cell group.
Each battery cell group is connected with a bypass resistor and a switch in parallel. During the
charging process, if the highest-voltage battery cell group reaches the set balancing starting
voltage and the voltage difference between the highest-voltage and the lowest-voltage battery
cell group exceeds the set voltage difference, the switch connected to the highest-voltage
battery cell group will be closed to shunt the charge current around the highest-voltage battery
cell group through the bypass resistor until the voltage difference drops below the set value. To
avoid excessive energy loss, the battery cell balancing is only performed during the charging
process.
