To provide a power supply device and a switching module capable of suppressing lowering of power supply voltage with respect to a load on a sub-battery side according to the turning-off of a switch.SOLUTION: A lead-acid battery 12 can charge generation power by an alternator 11. An Li battery 13 is connected in parallel with respect to the lead-acid battery 12. An FETQ is provided between the alternator 11 and the lead-acid battery 12 and the Li battery 13, and it switches the electric conduction and cut-off of the alternator 11 and the lead-acid battery 12 and the Li battery 13. A capacitor C is provided further on the Li battery 13 side than the FETQ, and is connected in parallel with the Li battery 13.SELECTED DRAWING: Figure 1
【課題】スイッチのオフに伴うサブバッテリ側の負荷に対する電源電圧の低下を抑制することができる電源装置及び切替モジュールを提供する。【解決手段】鉛バッテリ12は、オルタネータ11による発電電力を充電可能である。Liバッテリ13は、鉛バッテリ12に対して並列接続される。FETQが、オルタネータ11及び鉛バッテリ12とLiバッテリ13との間に設けられ、オルタネータ11及び鉛バッテリ12とLiバッテリ13との通電及び遮断を切り替える。コンデンサCを、FETQよりもLiバッテリ13側に設け、Liバッテリ13と並列接続させる。【選択図】図1
