Claim:
1. A method of controlling a high-temperature storage battery connected to an electric power system after supplying electric power from an electric power supply to a heater to provide thermal energy to the storage battery during activation of the storage battery, the method comprising the steps of: measuring a temperature of the storage battery; determining whether the measured temperature of the storage battery is equal to or lower than a predetermined reference temperature; and charging and discharging the storage battery with charging and discharging electric power based on a predetermined operating process for the storage battery; and controlling the charging and discharging when the temperature of the storage battery is equal to or lower than the predetermined reference temperature, wherein: in the step of controlling the charging and discharging, the storage battery is charged and discharged with charging and discharging electric power, which is a sum of the charging and discharging electric power based on the predetermined operating process for the storage battery and charging and discharging electric power corresponding to charging and discharging cycles in which each of a continuous charging time is 1 hour or shorter and each of a continuous discharging time is 1 hour or shorter, for thereby generating thermal energy in the storage battery to increase the temperature of the storage battery to be at least equal to the reference temperature without supplying electric power to the heater.
