The invention discloses a power generation control method and device for an extended-range electric vehicle, a server and a medium, and the method comprises the steps: collecting a first residual electric quantity, and collecting a first real-time vehicle speed when judging that the first residual electric quantity is smaller than a first preset threshold value and is greater than or equal to a second preset threshold value; when it is judged that the first real-time vehicle speed is larger than a first preset speed, a range extender power generation strategy database is called, and then a power generation mode corresponding to the first real-time vehicle speed is determined; and driving the range extender in a power generation mode corresponding to the first real-time vehicle speed, collecting a second real-time vehicle speed and a second residual electric quantity, if the second real-time vehicle speed is greater than or equal to a second preset speed or the second residual electric quantity is less than or equal to a third preset threshold value, repeating the step, otherwise, stopping the operation of the range extender. Different power generation strategies are adopted in combination with the current vehicle speed and the remaining electric quantity of the range-extending type electric vehicle, long-time low-power power generation of the range extender is avoided, the running time proportion of low-efficiency working condition points is reduced, and fuel economy is improved.
本申请公开了一种增程式电动汽车的发电控制方法、装置、服务端及介质,所述方法包括:采集第一剩余电量,判断第一剩余电量小于第一预设阈值时且大于等于第二预设阈值时,采集第一实时车速;判断第一实时车速大于第一预设速度时,调用增程器发电策略数据库,随后确定与第一实时车速对应的发电模式;以第一实时车速对应的发电模式驱动增程器,采集第二实时车速和第二剩余电量,若第二实时车速大于等于第二预设速度或第二剩余电量小于等于第三预设阈值,重复执行本步骤,反之,则停止增程器运行。本申请结合增程式电动汽车当前车速以及剩余电量采用不同的发电策略,避免增程器长时间低功率发电,减少低效工况点的运行时间占比,提高燃油经济性。
