Abstract
A battery module includes: a battery cell unit including a plurality of battery cells connected together in series or series-parallel; a cell monitoring unit configured to monitor temperatures and voltages of the battery cells; and a plurality of overtemperature/overvoltage detecting units of n systems (n: an integer greater than or equal to 2). The overtemperature/overvoltage detecting units of the n systems are configured to independently detect an overtemperature or an overvoltage of the battery cells as an abnormal state, and to mutually notify one another of results of the detection. Each of the overtemperature/overvoltage detecting units is configured to, upon being notified that the abnormal state is detected from another overtemperature/overvoltage detecting unit of another system in the battery module, operate on the assumption that the overtemperature/overvoltage detecting unit detects the abnormal state.
