The invention is suitable for the field of vehicle energy management, and provides a hydrogen energy city domain train energy management cooperative control system which comprises a fuel cell system, a hydrogen storage system, a heat dissipation system, an energy storage system, a traction system, an auxiliary power supply system and an energy management system on a hydrogen energy city domain train. The energy management system carries out energy distribution on a coupling power supply mode of a hydrogen fuel cell and a lithium ion storage battery in the fuel cell system and a super capacitor in the energy storage system, so that the system can realize power supply modes under a low-power traction working condition, a high-power traction working condition and a regenerative braking working condition. Therefore, according to the system, the hydrogen fuel system and the energy storage system form a power system to drive the train, and the defects that a hydrogen fuel cell is slow in starting characteristic, poor in dynamic response characteristic and incapable of recycling braking energy are overcome; overall management is carried out on whole vehicle energy control and load energy consumption, and energy distribution is carried out on a multi-energy coupling power supply mode, so that the whole vehicle energy utilization rate is increased.
