A power control system includes: an ECU configured to control (i) charging from a power facility to a vehicle and (ii) discharging from the vehicle to the power facility; and a user terminal configured to allow a user to separately set a charging power setting value and a discharging power setting value. When the charging from the power facility to the vehicle is performed, the ECU is configured to control power charged to the vehicle per unit time to correspond to the charging power setting value set by the user using the user terminal. When the discharging from the vehicle to the power facility is performed, the ECU is configured to control power discharged from the vehicle per unit time to correspond to the discharging power setting value set by the user using the user terminal.
