When a PCU (inverter) of an electrically powered vehicle fails, a first map where a temperature and a current of a battery are defined as parameters or a second map where a temperature and a rate of change in voltage of the battery are defined as parameters is used to determine whether or not rapid deterioration of the battery has occurred. When it is determined that the rapid deterioration of the battery has occurred, a battery replacement indicator is turned on.
