BATTERY BALANCING SYSTEM AND OPERATING SYSTEM THEREOF

A battery balancing system includes a battery pack block configured in rows and columns of batteries, a balancing block with balancing devices corresponding to the batteries, a balancing control block with control circuits that selectively connect batteries and balancing devices to perform balancing. The control circuits enable connections between a battery and its corresponding or adjacent balancing devices, or between adjacent batteries and corresponding balancing devices, based on control signals. The system further includes a state determination block that determines the state of batteries on a column basis, and a system controller that activates selected rows and controls the balancing connections based on the state determination result.
