A battery management system (BMS) for actively balancing the voltages and capacities of battery cells in a serial battery pack is provided. The BMS uses an array of synchronized voltage monitors to detect underperforming cells in the battery pack, and employs high speed parallel energy transfers to actively balance the voltages and capacities of cells which exceeds a preset threshold limit against the average voltage and capacity of the remaining cells in the battery pack as an integrated unit. The BMS works both in charging and discharging operations, and is particularly useful for improving the overall performance of the battery packs in applications which require frequent high energy output rate, deep discharging, and fast charging operations. |
