CHARGE/DISCHARGE SYSTEM

A charge/discharge system includes: first and second electric chargers that supplies electric power to a motor generator and charges electric power generated by a motor generator; an electric power converter; and a controller. The controller controls the electric power converter such that electric power charged in the first electric charger is supplied to the motor generator, electric power charged in the second electric charger is charged in the first electric charger when a charging capacity of the first electric charger is lower than a second predetermined value. The driving force of the motor generator is reduced depending on the charging capacity when the charging capacity of the first electric charger is lower than the first predetermined value.
