Abstract
When the voltage value of the capacitor included in the PCU is equal to or higher than a predetermined value, the vehicle power supply device turns on both the positive switching element and the negative switching element corresponding to one of a plurality of resistors so as to activate the one resistor connected to the initially disabled PCU. In addition, the vehicle power supply device turns on both the positive switching element and the negative switching element corresponding the other one of the resistors so as to deactivate the one resistor and activate the other one resistor based on a predetermined condition.
