The invention relates to the technical field of electric vehicles, and provides a power management method and device for an electric vehicle in an ultra-high-speed driving state and the electric vehicle. The method comprises the steps that when the remaining power is within a preset remaining power interval, it is detected that the vehicle is in the ultra-high-speed driving state; if yes, judging whether the residual electric quantity reduction amplitude of the vehicle within the first preset duration is greater than or equal to a preset amplitude threshold value or not; if yes, detecting whether an available charging pile exists in a navigation pre-estimated travelable mileage range of the remaining electric quantity of the vehicle; if yes, according to the current position of the vehicle, calculating whether the difference value between the vehicle navigation estimated travelable mileage and the mileage from the vehicle navigation to the available charging pile is greater than or equal to a preset mileage threshold value or not: if not, sending first user reminding information; when a confirmation request feedback of agreeing to navigate to the nearest charging pile is received, navigating to the nearest charging pile; if not, second user reminding information is sent out, so that the risk of midway feed parking of the vehicle is reduced.

    本申请涉及电动车技术领域,提供了一种电动车超高速行驶状态下的电量管理方法、装置和电动车,该方法包括:当剩余电量在预设的剩余电量区间时,检测车辆处于超高速行驶状态;若是,判断车辆在第一预设时长内的剩余电量下降幅度是否大于或等于预设的幅度阈值;若是,检测车辆剩余电量的导航预估可行驶里程范围内有无可用充电桩;若有,根据车辆当前位置,计算车辆导航预估可行驶里程与车辆导航到可用充电桩里程的差值是否大于或等于预设的里程阈值:若否,发出第一用户提醒信息;当接收到同意导航去最近的充电桩的确认请求反馈时,导航至最近的充电桩;若没有,发出第二用户提醒信息,以此来降低车辆中途馈电停车的风险。
