Abstract
An inductor (L), capacitor (C) and alternator (OSC) are connected in series to the positive and negative poles of a battery (15). The temperature of the battery (15) is increased by causing the alternator (OSC) to generate an alternating current having the resonance frequency of the inductor (L) and capacitor (C). The alternating current is consumed by the internal resistance of the battery (15) due to the resonance of the inductor (L) and capacitor (C), and the temperature of the battery (15) therefore rises due to the heat thereby generated in the battery. In this way, the temperature of the battery (15) can be effectively increased with minimum power consumption.
