Abstract: A battery balancing method for a battery pack is disclosed, wherein the battery pack includes a plurality of rechargeable battery cells. The method categorizes the plurality of battery cells into a first subgroup and a second subgroup. Each battery cell in the first subgroup has an over voltage count number that records the times of the battery cells reaching an over voltage protection point. A minimum voltage of the battery cells in the second subgroup is detected. Then the voltage of each battery cell in the first subgroup is decreased to a buck voltage lower than the minimum voltage of the second subgroup. While any one cell in the first group reaches the over voltage protection point again during the charging procedure, the over voltage count numbers for the particular battery cells already reached the over voltage protection point are accumulated and then the charging procedure is terminated.
