Abstract
An apparatus and method for protecting each of a plurality of cell stacks included in a battery pack from overcharge. The overcharge prevention apparatus prevents the overcharge of a plurality of cell stacks connected in series within a high current path. The overcharge prevention apparatus includes a voltage measuring unit configured to measure voltage of each cell stack, and generate a first monitoring signal indicating the measured voltage, a current regulating unit configured to selectively provide a bypass path to each cell stack, and a controller connected to the voltage measuring unit and the current regulating unit allowing communication. The controller is configured to control the current regulating unit based on the first monitoring signal from the voltage measuring unit.
