When the auxiliary battery is being charged and the difference between the voltage value of the auxiliary battery and the target voltage value of the DCDC converter is equal to or greater than the determination voltage value, the vehicle power supply system determines that the DCDC converter is abnormal, stops the DCDC converter, drives the alternator, and decreases the determination voltage value when the voltage value of the auxiliary battery is equal to or less than the predetermined voltage value or the internal resistance value of the auxiliary battery is equal to or less than the predetermined resistance value.
