The invention discloses a control method, device and equipment for direct current discharge of an extended-range electric vehicle and a medium, and relates to the technical field of vehicle-to-vehicle charging. The control method comprises the steps that in response to an external discharging instruction, discharging cut-off electric quantity set by a user and real-time remaining electric quantity of a target vehicle are obtained; if the real-time residual electric quantity is greater than the discharge cut-off electric quantity, controlling a battery module of the target vehicle to output the electric quantity; when the battery module outputs the electric quantity outwards, the remaining electric quantity of the target vehicle at all moments is obtained, and when the remaining electric quantity is equal to the discharging cut-off electric quantity, the real-time oil quantity of a range extender of the target vehicle is obtained; and if the real-time oil quantity is larger than the preset oil quantity threshold value, the range extender is started to charge the battery module. According to the method, when the residual electric quantity of the battery module is insufficient, the vehicle economy is improved in the mode that the range extender is used for charging the battery module, and meanwhile the charging efficiency can be effectively improved.

    本申请公开了一种增程式电动汽车直流放电的控制方法、装置、设备及介质,涉及车对车充电技术领域。所述控制方法包括:响应于对外放电指令,获取用户设定的放电截止电量与目标车辆的实时剩余电量;若实时剩余电量大于放电截止电量,则控制目标车辆的电池模块对外输出电量;在电池模块对外输出电量时,获取各时刻下目标车辆的剩余电量,当剩余电量等于放电截止电量时,获取目标车辆增程器的实时油量;若实时油量大于预设油量阈值,则启动增程器向电池模块进行充电。该方法通过在电池模块剩余电量不足时,利用增程器为其补电的方式来提高车辆经济性,同时也可以有效提高充电效率。
