Range-extended vehicle energy control method and system and storage medium

The invention discloses a range-extended vehicle energy control method. The method comprises the steps of obtaining to-be-driven road information of a vehicle; determining a to-be-driven road condition according to the to-be-driven road information; and when the to-be-driven road condition comprises downhill, controlling a range extender of the vehicle to stop charging a vehicle battery. The invention further discloses a range-extended vehicle energy control system and a storage medium. According to the embodiment of the invention, the vehicle energy is controlled, so that energy braking is adopted or mainly adopted in the downhill process, the service time of mechanical braking is shortened, and the situation that the mechanical braking fails and is abraded due to the fact that the temperature is too high in the mechanical braking process in the downhill road condition can be effectively avoided. 本发明公开一种增程式车辆能量控制方法，获取车辆待行驶道路信息；根据所述待行驶道路信息确定待行驶路况；所述待行驶路况包括下坡时，控制所述车辆的增程器停止向车辆电池充电。本发明还公开一种增程式车辆能量控制系统和存储介质。本发明实施
