To provide a power supply device capable of properly using a DC power supply and an AC power supply.SOLUTION: In a power supply device 1, a common power supply terminal 32 has a shape in which power supply terminals (a positive electrode terminal Tp and a negative electrode terminal Tn) of a DC power supply DC outside a vehicle V and power supply terminals (a first terminal T1 and a second terminal T2) of an AC power supply AC outside the vehicle V can be connected in common. An AC power supply line connects the common power supply terminal 32 and a battery 10 via an AC/DC conversion part 60. A DC power supply line connects the common power supply terminal 32 and the battery 10 without going through the AC/DC conversion part 60. For example, a control part 80 charges the battery 10 with a power that is input to the common power supply terminal 32 by switching to the DC power supply line when the power supply connected to the common power supply terminal 32 is the DC power supply DC, or by switching to the AC power supply line when the power supply connected to the common power supply terminal 32 is the AC power supply AC.SELECTED DRAWING: Figure 1 【課題】直流電源と交流電源とを適正に使い分けることができる電源装置を提供する。【解決手段】電源装置１において、共通電源端子３２は、車両Ｖの外部の直流電源ＤＣの電源端子（正極端子Ｔｐ及び負極端子Ｔｎ）及び車両Ｖの外部の交流電源ＡＣの電源端子（第１端子Ｔ１及び第２端子Ｔ２）に共通に接続可能な形状である。ＡＣ電源ラインは、ＡＣ／ＤＣ変換部６０を介して共通電源端子３２及びバッテリ１０を接続する。ＤＣ電源ラインは、ＡＣ／ＤＣ変換部６０を介さずに共通電源端子３２及びバッテリ１０を接続する。制御部８０は、例えば、共通電源端子３２に接続される電源が直流電源ＤＣの場合、ＤＣ電源ラインに切り替え、且つ、共通電源端子３２に接続される電源が交流電源ＡＣの場合、ＡＣ電源ラインに切り替えることで、共通電源端子３２に入力された電力をバッテリ１０に充電する。【選択図】図１
