Classification: CPC H  Y | IPC H

Claim 6:
7. A battery management system comprising:
a plurality of balancing resistors respectively forming balancing discharging paths of cells connected in series to each other;
a plurality of balancing switches respectively connected between the cells and the balancing resistors for controlling a cell-balancing of each of the cells;
a voltage-detecting circuit for detecting cell voltages of the cells;
a battery controller for acquiring balancing capacities of the cells based on the cell voltage, and for obtaining duty cycles of the balancing switches according to the balancing capacities; and
a battery integrated circuit for controlling operation of the balancing switches by using a balancing task, which is repeatedly executed during an execution cycle that is shorter than a balancing cycle, and which corresponds to the duty cycles, to allow a turn-on state of the balancing switches only during a part of an execution period of the balancing task.
