The invention discloses an external discharge control system and method and a vehicle, and relates to the technical field of new energy vehicles. The external discharge control system comprises a vehicle control unit and a vehicle-mounted bidirectional charger, the vehicle control unit is used for responding to an obtained external discharging instruction and judging whether the vehicle meets external discharging conditions or not, and the external discharging conditions are that the current electric quantity of the high-voltage battery is larger than or equal to a high-voltage battery discharging threshold value, the discharging gun is in a connected state, and the vehicle speed of the whole vehicle is smaller than or equal to a vehicle static threshold value; if yes, sending an external discharge enabling instruction to the vehicle-mounted two-way charger after controlling high-voltage electricity on the whole vehicle; and the vehicle-mounted bidirectional charger is used for responding to the external discharge enabling instruction and executing external discharge. Therefore, the problem that the alternating current charging port generates high voltage due to the fact that the vehicle control unit sends the external discharging request unexpectedly can be avoided, and therefore the reliability and safety of discharging are improved.
本申请公开了一种对外放电控制系统、方法及车辆,涉及新能源车辆技术领域。该对外放电控制系统包括:整车控制器和车载双向充电机;整车控制器用于响应于获取到的对外放电指令,判断车辆是否满足对外放电条件,所述对外放电条件为当前高压电池电量大于或等于高压电池放电阈值,且,放电枪连接状态为已连接,且,整车车速小于或等于车辆静止阈值;若是,则在控制整车上高压电后,向所述车载双向充电机发送对外放电使能指令;车载双向充电机,用于响应于所述对外放电使能指令,执行对外放电。由此,可以规避由于整车控制器非预期地发送对外放电请求,导致交流充电口产生高压电的问题,从而提升放电的可靠性和安全性。
