An HV-ECU continuously integrates non-external charging time (Tcum) which is elapsed time from the last external charging (previous external charging). When ignition is turned on, the HV-ECU refers to a map for storing an SOC control center value to acquire the SOC control center value corresponding to the non-external charging time (Tcum) at the time.
