The invention provides an external discharge method and device and an automobile, and relates to the technical field of automobiles. The method comprises the steps of when a discharge gun is connectedwith an alternating current charging port of a vehicle to be discharged, detecting discharge button information triggered when a discharge button is pressed down; if it is detected that the dischargebutton information is discharge enabling information, detecting a cut-off discharge mileage set by a user on an instrument and the current remaining electric quantity of the vehicle to be discharged;and if the current endurance mileage corresponding to the current remaining electric quantity is greater than the cut-off discharge mileage, sending a discharge function enabling instruction to a bidirectional inverter controller, and controlling the bidirectional inverter controller to start a discharge function. According to the scheme, an interaction link between a user and the discharging system is added, the user can switch on or off the discharging function through the discharge button, the cut-off discharge mileage on the instrument can be set in a user-defined mode to adjust the cut-off value of external discharge of the vehicle, and the user experience is improved while the power utilization safety is guaranteed.

    本发明提供了一种对外放电方法、装置及汽车,涉及汽车技术领域。该方法包括:当放电枪与待放电车辆的交流充电口连接时,检测放电按钮被按下时所触发的放电按钮信息;若检测到所述放电按钮信息为放电使能信息,则检测仪表上用户设置的截止放电里程和所述待放电车辆的当前剩余电量;若所述当前剩余电量对应的当前续航里程大于所述截止放电里程,则发送放电功能使能指令到双向逆变控制器,控制所述双向逆变控制器开启放电功能。上述方案,增加了用户与放电系统交互环节,用户可以通过放电按钮进行放电功能的开关,可以自定义设置仪表上的截止放电里程调整车辆对外放电的截止值,在保证用电安全的同时,提高了用户的体验。
