Description of the Related Art In an electric vehicle equipped with a battery for driving a motor, when the temperature of the battery falls below an appropriate temperature range, the electromotive force of the battery falls and the running performance decreases. In particular, in cold weather or in cold regions, the temperature of the battery may drop below an appropriate temperature, for example, at night when operation is stopped, and it may even be difficult to start the motor the next morning. The situation is the same in a vehicle equipped with a battery for starting the engine, and the startability of the engine deteriorates due to a decrease in the electromotive force of the battery. Therefore, there has been a demand for measures to keep the battery warm in cold weather or in cold regions.
