  The BMS Main 3 can enable the cell balancing by the external “Balancing request” signal. Balancing process will be started to cells which the voltage is higher than the balancing start voltage and the difference between the cell voltage and the minimum voltage among all the cells is greater than the balancing stop threshold.
--BMS Main 3 can force a cell balancing, if its voltage is higher than estimated value.
