The invention provides an electric vehicle energy management method, a controller and an electric vehicle, and relates to the field of energy recovery, and the method comprises the steps that the controller can obtain the running mode and vehicle state information of the electric vehicle; the controller can start the energy recovery preparation mode and end the range extending mode when the electric vehicle is in the range extending mode and the vehicle state information meets the first preset condition. And when the controller determines that the electric vehicle is in the energy recovery preparation mode and the vehicle state information meets a second preset condition, the controller controls the electric vehicle to enter the range extending mode, and the energy recovery preparation mode is ended. According to the method, the energy recovery efficiency is improved.

    本申请提供一种电动汽车能量管理方法、控制器和电动汽车,涉及能量回收领域,该方法包括:控制器可以获取电动汽车的运行模式和车辆状态信息。控制器可以在电动汽车处于增程模式,且车辆状态信息符合第一预设条件时,开启能量回收准备模式,并结束增程模式。控制器还可以再确定电动汽车处于能量回收准备模式,且车辆状态信息符合第二预设条件时,控制电动汽车进入增程模式,并结束该能量回收准备模式。本申请的方法,提高了能量回收效率。
