生ずる。2. Description of the Related Art In a general automobile, a transmission is configured so that a rotor shaft of a generator is driven at a constant speed increase ratio by an output shaft of an engine, and the generator is rated even when the engine is idling. The engine is rotated near the rotation speed to ensure the minimum required amount of charge, but in such a case, when the engine is running at a high speed, the generator is rotated at an excessive speed and the power loss is increased. In addition, there is a disadvantage that the durability of the generator is reduced.
