An automatic changeable electromotive vehicle has a driving device. The driving device of the electromotive vehicle is connected to a battery and a generator to form an electric loop. A switch is connected between the battery and the driving device. Therefore, when the switch of the electromotive vehicle is turned on, the battery provides power to the driving device so as to drive the electromotive vehicle. While the driving device also drives the generator to operate, the generator precedes battery to charge. The electromotive vehicle is chargeable automatically during driving. Thus, not only the battery of the electromotive vehicle is charged in driving, but also the traveling distance of the electromotive vehicle is increased.
