To provide a power control unit enabling efficient charge and discharge of power storage equipment at high speed.

A power control unit 10 includes: power storage equipment 11 which is incorporated into the power control unit 10, can store electric power generated by a drive motor 43 and can supply the stored electric power to a discharge target; and charge/discharge switches 21, 31 which is each incorporated into the power control unit 10 and switches charge/discharge of the power storage equipment 11 by turning on/off electric power supply from the drive motor 43 to the power storage equipment 11 and turning on/off electric power supply from the power storage equipment 11 to the discharge target. The power control unit 10 acquires a power storage state of the power storage equipment 11, and controls the respective charge/discharge switches 21, 31 based on the power storage state to switch charge/discharge of the power storage equipment 11. The power control unit 10 and a DC power source device 45 which are operated by directly supplying electric power stored in the power storage equipment 11 serve as the discharge targets of the power storage equipment 11.
