A charge/discharge system is capable of supplying electric power to an electric motor generator and capable of charging with regenerative electric power from the electric motor generator. The charge/discharge system includes: a capacitor connected to the electric motor generator; a secondary battery connected in parallel to the capacitor; an electric power converter placed between the capacitor and the secondary battery to increase/decrease the charge/discharge voltage of the secondary battery; and a controller to control the electric power converter. If the SOC of the secondary battery is equal to or greater than a preset first setting value, the controller controls so that regenerative electric power of the electric motor generator is stored in the capacitor only, and if the SOC of the secondary battery falls below the first setting value, a part or an entire of the regenerative electric power of the electric motor generator is stored in the secondary battery.
