New energy automobile energy management method, system and device and storage medium

The invention relates to a new energy automobile energy management method and system and a storage medium. Comprising the step of solving an energy management problem of the fuel cell vehicle by adopting a PI-PMP method. The method comprises the following steps: firstly, establishing a simulation model of a fuel cell automobile power system, including a fuel cell system, a power cell and a motor system; and then constructing an optimization problem taking the minimum hydrogen consumption as an optimization target based on a PMP algorithm, and discussing the influence of different covariables on a calculation result. And finally, a covariable in a PMP algorithm is adjusted through a PI controller, and the fuel consumption of the fuel cell vehicle is reduced while the SOC state of the battery is controlled. And the battery management method is relatively good in energy saving performance and relatively high in calculation efficiency. 本申请涉及一种新能源汽车能量管理方法、系统、和存储介质。包括：采用PI-PMP方法来求解燃料电池汽车的能量管理问题。首先，建立燃料电池汽车动力系统的仿真模型
