PROBLEM TO BE SOLVED: To provide a power supply device and a power supply system that can suppress flowing of excess current in a switch.SOLUTION: A control unit 51 performs replacement of switches in a closed state in a state that either one of switches 23, 24 is closed when a predetermined condition is satisfied. At that time, the control unit 51 temporarily makes both switches 23, 24 to be in a closed state, and performs the replacement on condition that current flowing in electric paths L3, L4 in the closed state is in a predetermined state being lowered. Specifically, the control unit 51 performs the replacement of on and off of the switches 23, 24 to each other in the electric paths L3, L4 while maintaining its conduction state after electric paths L1, L2 between a lead-acid battery 11 and a lithium-ion battery 12 is made to be the conduction state.SELECTED DRAWING: Figure 1
【課題】スイッチに過電流が流れることを抑制することができる電源装置及び電源システムを提供すること。【解決手段】制御部51は、所定条件成立時に、スイッチ23,24のうちいずれか一方が閉鎖された状態でその閉鎖状態のスイッチを入れ替える。その際、制御部51は、一時的にスイッチ23,24を共に閉鎖状態とし、その閉鎖状態で電気経路L3,L4に流れる電流が低減されている所定の低減状態であることを条件に、その入れ替えを実施する。具体的には、制御部51は、鉛蓄電池11とリチウムイオン蓄電池12との間の電気経路L1,L2を通電状態とした後に、その通電状態を維持したまま、電気経路L3,L4におけるスイッチ23,24のオンオフを相互の切り替えを行う。【選択図】 図1
