To provide a protection control device for engine starting battery which can properly protect an engine starting battery from over-discharging.SOLUTION: A protection control device for engine starting battery which is a power supply for a cell motor that cranks the engine includes: a control ECU that controls charging/discharging of one or more battery cells constituting the engine starting battery; and a protection circuit that protects the one or more battery cells from overcharging and overdischarging the one or more battery cells. The control ECU limits the supply of electricity to the cell motor when a battery voltage when the engine switch is turned on is lower than a predetermined first predetermined value.SELECTED DRAWING: Figure 8

    【課題】エンジン始動用バッテリーを過放電から適切に保護できるエンジン始動用バッテリーの保護制御装置を提供する。【解決手段】エンジン始動用バッテリーの保護制御装置は、エンジンをクランキングさせるセルモータの電源となるエンジン始動用バッテリーの保護制御装置であって、前記エンジン始動用バッテリーを構成する一又は二以上のバッテリーセルの充放電を制御する制御ECUと、前記一又は二以上のバッテリーセルの過充電及び過放電から前記一又は二以上のバッテリーセルを保護する保護回路と、を備え、前記制御ECUは、エンジンスイッチのオン時のバッテリー電圧が予め定められた第1の所定値を下回る場合に、前記セルモータへの電気の供給を制限する。【選択図】 図8
