Vehicle-mounted fuel cell hybrid power system and energy management method thereof

The invention relates to the technical field of digital rail vehicle hybrid power and network control systems, and discloses a vehicle-mounted fuel cell hybrid power system and an energy management method thereof, and the method comprises the steps: S1, setting control parameters and super-capacitor system Lenberger observer parameters; s2, calculating an equivalent power consumption coefficient of the super capacitor according to the control parameters and parameters of a super capacitor system Lenberger observer; and S3, calculating an output power set point of a DC/DC converter cascaded with the fuel cell system based on the equivalent power consumption coefficient of the super capacitor. According to the method, an electricity-hydrogen conversion calculation method is innovated, the output power of the fuel cell is accurately controlled through the observer, the energy efficiency of the hybrid power system is improved, the operation cost and the maintenance expenditure are reduced, meanwhile, the service
