A vehicle power supply device includes a power storage device, a relay device, a current sensor, and a control device. The control device instructs the external power supply to stop outputting the supply power when a current value abnormality is detected during charging of the power storage device. The control device further controls the timing at which the switch of the relay device is turned off on the basis of the state of the current value and the state of the amount of power charged into the power storage device after the output of the command is stopped.

    车辆电源装置包括蓄电装置、继电器装置、电流传感器和控制装置。控制装置当在蓄电装置的充电期间检测到电流值异常时,指令外部电源停止输出供给电力。控制装置还在指令停止输出之后,基于电流值的状态和充电至蓄电装置的电力量的状态,控制切断继电器装置的开关的时刻。
