The invention discloses a retarding device for a pure electric vehicle, which is characterized in that a retarding handle, a BMS (Battery Management System), an MCU (Microprogrammed Control Unit) and an instrument are respectively connected with a vehicle control unit through CAN (Controller Area Network) lines, and the MCU is connected with a power battery and a control motor through high-voltage cables. The BMS battery system sends state information of a power battery to the CAN line in a message mode, the MCU microcontroller sends state information of a power system to the CAN line in a message mode, and the whole vehicle controller receives information sent by the retarding handle, the BMS battery system and the MCU microcontroller. And the kinetic energy of the vehicle can be recycled while the vehicle retarding function is achieved, and the utilization efficiency of the energy is improved. The retarding device can work together with a traditional brake of an automobile, and the brake performance of the automobile is improved.

    本发明公开了一种纯电动汽车用缓速装置,缓速手柄、BMS电池系统、MCU微控制器和仪表分别通过CAN线与整车控制器连接,MCU微控制器通过高压线缆与动力电池和控制电机连接。BMS电池系统将动力电池的状态信息,通过报文的形式发送到CAN线上,MCU微控制器将动力系统的状态信息,通过报文的形式发送到CAN线上,整车控制器接收来自缓速手柄、BMS电池系统、MCU微控制器发送的信息,本发明提供了一种安全环保的缓速装置,能够在实现车辆缓速功能的同时,可以对车辆的动能进行回收,提高了能量的利用效率。该缓速装置可以和汽车传统制动一起工作,提高车辆的制动性能。
