PROBLEM TO BE SOLVED: To provide a battery control device capable of ensuring the travel of a vehicle even if a shock is input to the vehicle.SOLUTION: A battery control device is applied to an electric vehicle driving an electric motor 1 for vehicle travel using a first battery pack 4 mounted at a predetermined position of a vehicle body and a second battery pack 5 mounted at another location of the vehicle body and electrically connected to the first battery pack 4. The battery control device comprises a switching circuit 6 cutting off the electrical connection between the first battery pack 4 and the second battery pack 5 and supplying power to the electric motor 1 from a predetermined number of series connected unit cells among unit cells constituting the second battery pack 5 when a shock is input to the electric vehicle.

    【課題】車両が衝撃を受けた場合でも、車両の走行を確保できるバッテリ制御装置を提供する。【解決手段】バッテリ制御装置は、車体の所定位置に搭載された第1の組電池4と、車体の他の場所に搭載され。第1の組電池4と電気的に接続された第2の組電池5とを用いて車両走行用の電動モータ1を駆動する電動車両に適用される。バッテリ制御装置は電動車両への衝撃入力時に、第1の組電池4と第2の組電池5との電気的接続を遮断するとともに、第2の組電池5を構成する単電池のうち、所定個数の直列接続された単位電池から電動モータ1に電力を供給する切り換え回路6を備える。【選択図】図1
