Energy management system for electric vehicle

An energy management system for electronic vehicle is using a central control system with a standard transmission interface to communicate and exchange information with every module unit, a battery set, a motor driving system, a battery charger and a display device. Said central control system is the central control system of the whole electronic vehicle for collecting and monitoring the using status of said battery set. According to the rider's or driver's demand, it may determine the output power and drive the motor for providing sufficient power. Besides, the central control system may control the whole electronic vehicle information, so the operation status of the vehicle, such as battery balance volume, run-mileage, balance mileage, and/or maintenance information, may display on said display device for the rider or driver to control the vehicle.
