Hydrogen-fired engine range extender for power generation

The invention discloses a hydrogen-fired engine range extender for power generation, which is applied to a hydrogen-fired engine system. The hydrogen-fired engine system comprises a hydrogen-fired engine body, an engine cooling water tank, a motor cooling water pump, a motor cooling water tank, a high-voltage distribution box, an energy storage system, a whole vehicle VCU, an external charging port, a main drive motor controller, a main drive motor and a gearbox. The hydrogen combustion engine range extender for power generation comprises a motor, a motor controller and an integrated controller. The motor is mounted on the hydrogen-fired engine body, and the hydrogen-fired engine body is used for driving the motor to generate electricity; the motor controller is integrated on the motor and is electrically connected with the motor; the integrated controller is electrically connected with the hydrogen combustion engine body, the motor controller and the whole vehicle VCU. Therefore, the hydrogen-fired engine ra
