  "textContent": "A charge/discharge system includes a controller to control an electric power converter placed between a capacitor and a secondary battery connected in parallel. The controller includes: a request power calculation unit configured to calculate request input/o utput power for the electric motor generator based on current and voltage of the capacitor and input/output current of the electric power converter; a capacitor discharging bias factor map configured to specify a ratio of electric power to be supplied from the capacitor to the electric motor generator to the request input power of the electric motor generator; a capacitor charging bias factor map configured to specify a ratio of electric power to be stored in the capacitor from the electric motor generator to the request output power of the electric motor generator; and a subtraction unit configured to calculate charge/discharge power of the secondary battery by subtracting, from the request input/output power, the charge/discharge power of the capacitor.",
