A vehicle includes a power storage device, a discharging port, a power conversion circuit, and a controller. The discharging port includes a first output terminal, a second output terminal and a ground terminal. Each of the first output terminal and the second output terminal is not grounded to a body of the vehicle. The controller is configured to obtain a requested voltage value of a discharging connector connected to the discharging port. When the discharging connector is connected to the discharging port, the controller controls the power conversion circuit such that a voltage corresponding to the requested voltage value of the discharging connector is applied between the first output terminal and the second output terminal.
