The invention provides an energy management method and device for a hybrid vehicle and a storage medium, the method comprises the steps that the SOC of a current battery of the vehicle and the required power MCUPwr input by a motor system in real time are obtained, a start-stop instruction is output according to the SOC and the required power MCUPwr, and the start-stop instruction comprises a stop instruction and a start instruction; if the stopping instruction is output, a range extender or a power generation device of the vehicle is controlled to stop; if the starting instruction is output, a gain coefficient is obtained according to the deviation dSOC between the current battery SOC and the SOC set point, and a power instruction PwrIg of a range extender or a power generation device is output according to the gain coefficient; and controlling the range extender or the power generation device to respond to the power instruction PwrIg. Starting and stopping of the range extender or the power generation device and the size of the generated power are automatically adjusted according to the SOC and the required power input in real time, and the economical efficiency of a whole vehicle power system can be improved while the power requirements of different working conditions are met.
本发明提供一种混动车辆的能量管理方法、能量管理装置和存储介质,所述方法包括:获取车辆的当前电池的SOC和电机系统实时输入的需求功率MCUPwr,根据SOC和需求功率MCUPwr输出启停指令,启停指令包括停机指令和启动指令;如果输出停机指令,则控制车辆的增程器或发电装置停机;如果输出启动指令,则根据当前电池SOC与SOC设定点的偏差d_SOC获取增益系数,根据增益系数输出增程器或发电装置的功率指令PwrIgn;控制增程器或发电装置响应功率指令PwrIgn。本发明根据SOC和实时输入的需求功率自动调节增程器或发电装置的启停以及发电功率的大小,在满足不同工况功率需求的同时可以提升整车动力系统经济性。
