The invention relates to the technical field of extended-range automobiles, and provides an electric quantity management and control method and device for ultra-high-speed driving of an extended-range automobile and the extended-range automobile. The method comprises the steps that when the remaining electric quantity of the automobile is located in a preset electric quantity interval, whether the automobile is in an ultra-high-speed driving state within a plurality of different preset durations or not is detected; if the vehicle is in the first ultra-high-speed driving state within the first preset duration, and the range extender is in a normal starting state; judging whether the vehicle is in a second ultra-high-speed driving state within a second preset duration or not and whether the average generated power exceeds a calibration value or not; if yes, the vehicle speed energy consumption influence quantity is determined according to the average vehicle speed and average energy consumption of the vehicle within the second preset duration, and the vehicle speed energy consumption influence quantity and the whole vehicle energy consumption demand are added to obtain the power generation power requested by the power generator, so that the power generation power of the range extender is adjusted, and the effect of delaying and maintaining the electric quantity descending speed of the power battery is achieved.
本申请涉及增程汽车技术领域,提供了一种增程汽车超高速行驶的电量管控方法、装置和增程汽车,该方法包括在车辆的剩余电量位于预设电量区间时,检测车辆在预设的多个不同预设时长内是否处于超高速行驶状态;若车辆在第一预设时长内处于第一超高速行驶状态,并且增程器为能够正常启动状态;判断车辆在第二预设时长内是否处于第二超高速行驶状态,并且平均发电功率是否超过标定值;若超过,根据车辆在第二预设时长内的平均车速和平均能耗,确定车速能耗影响量,并将车速能耗影响量与整车能耗需求相加,得到发电机请求发电功率,以此来调整增程器发电功率,从而达到延缓和维持动力电池电量下降速度的效果。
