The present invention includes an AC generation circuit which is configured to be connected to a secondary battery having characteristics in which a resistance component of an impedance of the secondary battery decreases as a frequency of an alternating current flowing in the secondary battery rises from a low frequency and the resistance component increases as the frequency moves to a high frequency side from a frequency at which the resistance component is minimized and to raise the temperature of the secondary battery by circulating an alternating current at a frequency in a high frequency band higher than the frequency at which the resistance component is minimized in the secondary battery.
