The embodiment of the invention discloses an electric vehicle discharge control method, device and system. When a user inserts a discharging gun, a controller detects the resistance of a connection resistor so as to determine whether the inserted gun is a discharging gun or a charging gun; when the resistance of the connection resistor is discharge resistance, configuration information is sent toa battery management system so as to enable the battery management system to configure a discharge strategy of the battery according to the configuration information; when the controller obtains thatthe discharge strategy of the battery is vehicle-to-vehicle, a control guide signal is sent to a second vehicle through a cable so as to enable the second vehicle to perform safety strategy matching according to the control guide signal; and after the safety strategy matching is completed, the controller controls the battery of the first vehicle to charge the second vehicle through the cable, thatis, the electric vehicle (the first vehicle) with sufficient electric quantity is used for charging the electric vehicle (the second vehicle) with low electric quantity when there is no charging pile, and normal running of the second vehicle is guaranteed.

    本申请实施例公开了一种电动车辆放电控制方法、装置及系统,当用户插入放电枪后,由控制器检测连接电阻的阻值以根据该连接电阻的阻值确定插入的为放电枪还是充电枪。当连接电阻的阻值为放电电阻时,向电池管理系统发送配置信息,以使得电池管理系统根据配置信息配置电池的放电策略。当控制器获取到电池的放电策略为车对车时,通过电缆向第二车辆发送控制引导信号,以便第二车辆根据控制引导信号进行安全策略匹配。当安全策略匹配完成后,控制器控制第一车辆的电池通过电缆向第二车辆进行充电。即,在无充电桩的时候,利用电量充足的电动车辆(第一车辆)为电量较低的电动车辆(第二车辆)充电,保证第二车辆正常行驶。
