A display device is configured to display a screen showing, on the same graph in which an axis indicates time, a predicted transition of a first parameter relating to a remaining charge of a power storage device and a predicted transition of a second parameter relating to an amount of reward for energy management under an assumption that charge and discharge control is executed on the power storage device in response to a request for the energy management.

Control system for showing advantage and disadvantage of energy management request

In external charging, a first threshold voltage and a second threshold voltage which is lower than the first threshold voltage are set. The ECU permits start of charging of a battery when a voltage of the battery is lower than the second threshold voltage. The ECU stops charging of the battery and notifies the user that the battery has been fully charged using an HMI when the voltage of the battery is higher than the first threshold voltage during charging of the battery. The ECU notifies the user that the battery has been fully charged using the HMI when the voltage of the battery after charging of the battery has been stopped is lower than the first threshold voltage and is higher than the second threshold voltage.
