The invention relates to the technical field of extended-range electric vehicles, and provides a control method and device for rapid reduction of electric quantity of an extended-range electric vehicle and the extended-range electric vehicle. The method comprises the following steps: monitoring whether a vehicle runs at a high speed in a preset electric quantity interval to cause rapid reduction of electric quantity, if so, determining a vehicle speed compensation power generation demand based on a vehicle running speed parameter, and determining requested power generation power of a generator according to the vehicle speed compensation power generation demand and a whole vehicle energy consumption demand; and controlling the generator to start power generation, and adjusting the generated power of the generator based on the requested generated power. The motor generation power is controlled according to the situation that the vehicle runs at a high speed in the preset electric quantity interval, so that the electric quantity descending speed of the power battery is delayed and maintained, and the driving feeling and satisfaction degree of a user are improved.
本申请涉及增程电动车技术领域,提供了一种增程电动车电量快速下降的控制方法、装置和增程电动车。该方法包括:监测车辆在预设电量区间是否存在高速行驶导致电量快速下降的情况,若有,基于车辆行驶速度参数,确定车速补偿发电需求,并根据车速补偿发电需求和整车能耗需求,确定发电机的请求发电功率;控制发电机启动发电,并基于请求发电功率调整发电机的发电功率。本申请针对车辆在预设电量区间出现的高速行驶导致电量快速下降的情况进行电机发电功率控制,从而延缓和维持动力电池电量下降速度,提高用户驾驶感受和满意度。
