Abstract

A charge-discharge control system includes an electronic control unit. The electronic control unit is configured to: calculate an excess or shortage of a state of charge of the battery to a target state of charge as a state-of-charge difference; increase an output voltage of an electric power supply device when the shortage of the state of charge is larger than a first prescribed value; decrease the output voltage of the electric power supply device when the excess of the state of charge is larger than a second prescribed value; calculate an amount of change in the output voltage of the electric power supply device per unit time such that the amount of change in the output voltage of the electric power supply device per unit time is smaller when the calculated full charge capacity is low than when the calculated full charge capacity is high.
