Abstract

A battery overcharging prevention device includes a bypass circuit configured to bypass a current flowing into each of first to Nth battery modules that are connected in parallel (N being a natural number greater than or equal to 2) wherein each one of the first to Nth battery modules includes a plurality of battery cells connected in series; and a processor configured to prevent overcharging caused by charging and discharging performed between the first to Nth battery modules, wherein the processor is configured to detect a target battery module of the first to Nth battery modules in which an abnormal battery cell is present based on a voltage change in each of the battery cells in the first to Nth battery modules, and to prevent overcharging of the target battery module by bypassing the current flowing into the target battery module through the bypass circuit.
