The invention provides a control system of an electric car. The system comprises a driving control system, a vehicle control system, a battery management system, a vehicle-mounted charging machine, a DC/DC power supply converter, and a combined instrument. The vehicle control system comprises a brake energy feedback control module, an energy optimization module, and a fault diagnosis and protection module. The control system of the electric car has following beneficial effects: energy management can be carried out to different car types so that vehicle driving control is achieved; energy optimization is controlled; and brake feeding control and network management are achieved; the strategy is used more flexibility for applications of different car types and higher adaptability is obtained. 本发明提供的种电动车控制系统；包括驱动控制系统、整车控制系统、电池管理系统、车载充电机、DC/DC电源转换器、组合仪表，所述整车控制系统包括制动能量回馈控制模块、能量优化模块、故障诊断及保护模块；本发明可针对所配置的不同车型，进行相应的能量管理，实现整车驱动控制、能量优化控制、制动回馈控制和网络管理等功能。此策略在不同车型的应用上更灵活，适应性更强。
