The invention discloses a fuel cell hybrid power heavy truck layered energy management method and system. The method comprises the steps that the whole vehicle required power of an electric vehicle is obtained; considering the performance degradation of the multi-stack fuel cells and the performance degradation of the power cells, and constructing a fuel cell hybrid power heavy truck energy consumption cost minimization function; performing conversion processing on the fuel cell hybrid power heavy truck energy consumption cost minimization function, and performing solving through a depth deterministic strategy gradient algorithm to obtain a power distribution scheme of a multi-stack fuel cell and a power distribution scheme of a power cell; and power distribution is carried out through a virtual droop control method, and fuel cell hybrid power heavy truck layered energy management is completed. According to the embodiment of the invention, layered energy management can be carried out on the fuel cell hybrid power heavy truck, and reasonable power distribution among multiple energy sources of the fuel cell hybrid power heavy truck is realized. The method can be widely applied to the technical field of fuel cell electric vehicle energy management.
