The embodiment of the invention discloses an energy feedback system and method for an electric vehicle. The energy feedback system comprises an energy feedback controller, a battery assembly, a motorassembly, and a brake assembly; the energy feedback controller is electrically connected with the battery assembly, the motor assembly and the brake assembly; the brake assembly is used for generatingand outputting a braking signal when receiving a braking instruction input by a user; the energy feedback controller is used for obtaining the driving information of the electric vehicle through themotor assembly and the brake assembly when receiving the braking signal, and determining the target energy feedback strength according to the driving information of the electric vehicle; and the motorassembly is used for performing reverse braking according to the target energy feedback strength, and feeding back reverse braking energy through the energy feedback controller to charge the batteryassembly. In the embodiment of the invention, the energy feedback strength is dynamically changed, the speed of the whole vehicle is not seriously influenced, the reutilization of energy is realized,and the endurance mileage is prolonged.
本发明实施例公开了一种电动车的能量回馈系统及其方法,该能量回馈系统包括:能量回馈控制器、电池组件、电机组件和制动组件,能量回馈控制器分别与电池组件、电机组件和制动组件电连接;制动组件用于在接收到用户输入的制动指令时,生成制动信号并输出;能量回馈控制器用于在接收到制动信号时,通过电机组件和制动组件获取电动车行驶信息,根据电动车行驶信息确定目标能量回馈力度;电机组件用于根据目标能量回馈力度进行反向制动,并通过能量回馈控制器回馈反向制动能量给电池组件进行充电。本发明实施例中,使能量回馈力度动态变化,不会严重影响整车速度,实现能量的再次利用,延长续航里程。
