Abstract

A charge/discharge system includes first and second electric chargers that supplies electric power to a motor generator and charges electric power generated by the motor generator, an electric power converter that complementarily performs charging/discharging between the first and second electric chargers, and a controller. The controller controls the electric power converter based on charging conditions of the first and second electric chargers such that electric power charged in the first electric charger is charged in the second electric charger, or electric power charged in the second electric charger is charged in the first electric charger.
