The invention discloses an energy management method for a fuel cell hybrid electric vehicle. The method mainly comprises the steps of constructing a simulation environment, a training working condition and a verification working condition. Building an Actor network, a Critic network and a target network of the Actor network and the Critic network; training an energy management strategy to obtain inheritable network parameters; and the network parameters are loaded to a vehicle control unit to realize online application. According to the method, the Beta strategy is adopted to improve the standard SAC algorithm so as to improve the optimization performance; a proper weight coefficient is determined through multiple simulation experiments, and health constraints are emphasized, so that the driving cost is reduced, and the service life of a fuel cell hybrid electric vehicle (FCHEV) is prolonged; performance very close to a dynamic programming (DP) reference is achieved, and simulation results in different driving cycles show good adaptability.
