To provide a vehicle power supply device which can suppress the large size of the device.SOLUTION: A bidirectional two-phase chopper circuit 50 boosts a DC power voltage converted by an AC/DC converter unit 40 to output to a high-voltage battery 20, and also steps down a DC power voltage supplied from the high-voltage battery 20 to a low-voltage load unit 4. A connection part 61 is connected to a rapid charger 5 which supplies DC power. A connection part 62 is connected with a super-rapid charger 6 which supplies DC power whose voltage is higher than the voltage from the rapid charger 5.SELECTED DRAWING: Figure 1 【課題】装置の大型化を抑制することができる車両電源装置を提供する。【解決手段】双方向２相チョッパ回路５０は、ＡＣ／ＤＣ変換部４０により変換された直流電力の電圧を昇圧して高圧バッテリ２０に出力し、且つ、高圧バッテリ２０から低圧負荷部４に供給される直流電力の電圧を降圧する。接続部６１は、直流電力を供給する急速充電器５に接続される。接続部６２は、急速充電器５よりも高圧の直流電力を供給する超急速充電器６に接続される。【選択図】図１
