POWER SUPPLY APPARATUS AND POWER SUPPLY DEGRADATION DIAGNOSIS METHOD

摘要

A power supply apparatus includes a first electric accumulator, a second electric accumulator, and a control section which controls charge and discharge of the first electric accumulator and the second electric accumulator. When the control section does not carry out a degradation diagnosis of the first electric accumulator, the control section charges the first electric accumulator and makes the second electric accumulator discharge. When the control section carries out the degradation diagnosis of the first electric accumulator, the control section charges the second electric accumulator and then makes the first electric accumulator begin to discharge for the degradation diagnosis.
