N2 - This paper designs a hybrid power supply system with photovoltaic and PEMFC as the main power source and lithium battery as the auxiliary energy for electric vehicles. In order to coordinate the output power of the two power sources and the stability of the bus voltage, as well as improving the overall efficiency of the system, this paper designs a state machine energy management strategy with power compensation for the hybrid power supply system. By reducing the frequency of PEMFC output power changes and protecting the SOC of the lithium battery, the purpose of improving the service life of the PEMFC and the running time of the system is achieved. Through the efficiency analysis of the converters in the system, the output of the PEMFC and the lithium battery are adjusted to achieve the purpose of improving the overall operating efficiency of the system. Simulation results show that the designed energy management strategy can extend the system's running time and improve the overall efficiency of the system.
