PROBLEM TO BE SOLVED: To provide a power supply system for vehicles and method of controlling the power supply system, the system and method capable of turning on a relay between a battery and an auxiliary power unit at a timing evading generation of inrush current.SOLUTION: A power supply system for vehicles comprises: a battery for supplying power to loads of a vehicle; an auxiliary power unit to be connected to the battery; a relay for switching on/off of a connection state between the battery and the auxiliary power unit; a relay control unit for determining whether the relay can be set to an on state or not; and a battery voltage fluctuation information acquisition unit for acquiring information on voltage fluctuation of the battery. The relay control unit, on the basis of the information on the voltage fluctuation of the battery, determines whether the relay can be set to an on state or not.SELECTED DRAWING: Figure 3
【課題】突入電流の発生が回避されるタイミングでバッテリと補助電源部の間のリレーをオンにすることができる車両用の電源システム及び電源システム制御方法を提供すること。【解決手段】車両の負荷に電力を供給するバッテリと、バッテリに接続される補助電源部と、バッテリと補助電源部の間の接続状態のオン/オフを切り替えるリレーと、リレーをオン状態とすることが可能であるか否かを判断するリレー制御部と、バッテリの電圧変動の情報を取得するバッテリ電圧変動情報取得部と、を備え、リレー制御部は、バッテリの電圧変動の情報に基づいて、リレーをオン状態とすることが可能であるか否かを判断する車両用の電源システムを提供する。【選択図】図3
