A vehicle power supply apparatus includes first and second power supply systems, an accumulator sensor, and an abnormality determination unit. The first power supply system includes a generator and a first electrical energy accumulator. The second power supply system includes a second electrical energy accumulator and a group of electric devices. The accumulator sensor detects at least a discharge current of the second electrical energy accumulator. The abnormality determination unit determines that the second electrical energy accumulator is abnormal on the condition that the accumulator sensor is normal and the discharge current of the second electrical energy accumulator is equal to or smaller than a current threshold.
