Electric motor vehicle

Abstract

The electric motor vehicle of this invention is an electric motor vehicle which is provided with a drive motor (13) driven by electric power from a storage battery (11), an air conditioner (1), and a regenerative brake means which temporarily uses the motor (13) as a generator when decelerating the vehicle to generate regenerative electric power and to charge the storage battery (11). It is further provided with an excess regenerative electric power judging means (18) for judging excess regenerative electrical energy based on regenerative electrical energy by the regenerative brake and allowable regenerative electrical energy of the storage battery at that time, and an electric power distribution means (14) for distributing the excess regenerative electric power based on the excess regenerative electrical energy. This excess regenerative electric power is used to enhance an air conditioning capacity to stop the operation of the air conditioner (1) and accumulated as heat in heat accumulating means (30, 34) to enhance an air conditioning efficiency, thereby attaining a highly efficient and power saving air conditioner (1).
