Abstract: The power supply device performs one-side charge control for controlling the system main relay, the charging relay, the series connection relay, the parallel connection relay, and the first and second neutral point relays so that only the first power storage unit is charged using the external DC power until the voltage of the first power storage unit becomes equal to or higher than the voltage of the second power storage unit before the first and second neutral point relays are turned on and the power storage device is charged using the external DC power.

Abstract: In a power supply apparatus, a controller programmed to control the system main relay, the charging relay, the series connection relay, the parallel connection relay, and the first and second neutral point relays such that the first and second capacitors are both precharged, to detect the presence of an abnormality in a first current path charging the first capacitor based on voltage of the first capacitor, and to detect the presence of an abnormality in a second current path charging the second capacitor based on voltage of the second capacitor.

Abstract: Even in the case that the steered wheels are turned by an actual turning angle due to a disturbance from the road surface, and the steering shaft, which is mechanically connected to the steered wheels, attempts to rotate, a command current to an assist motor is set so that the actual turning angle becomes a corrected target turning angle. The force (torque) that attempts to cause rotation of the steering shaft due to the disturbance input from the road surface is instantaneously canceled by the assist motor.
