2. Description of the Related Art In recent years, the movement to protect the global environment is intensifying. Particularly, the air pollution caused by the consumption of a large amount of fossil fuel has become a serious problem. It is a very important issue in protecting the environment. Also in automobiles, engines using fossil fuels such as gasoline and light oil are now mainstream, and purification of exhaust gas from these engines is being promoted. On the other hand, so-called electric vehicles are attracting attention because they do not emit exhaust gas directly.

At present, various problems remain in practical use for this electric vehicle, and although it has been put to practical use in some fields, it has not come into widespread use. Therefore, in order to make the electric vehicle more practical, various technologies are currently proposed for the electric vehicle.

For example, it is known that deterioration of a battery such as a nickel-based battery greatly depends on a temperature environment, and that the battery is significantly deteriorated when it is charged and discharged at a high temperature. In particular, the battery heats up when the battery is charged and discharged, so the temperature environment at this time greatly affects the deterioration of the battery. That is, the deterioration of the battery is remarkable as the temperature becomes higher. For example, in the case of a nickel-based battery, when the battery is charged at a temperature of 45 ° C. or higher, it is rapidly deteriorated.
