The invention provides an external power supply system of a hydrogen energy automobile. The external power supply system comprises a hydrogen fuel cell system for providing power for the hydrogen energy automobile; a power battery which is used for storing surplus electric energy of the hydrogen fuel cell system; a high-voltage distribution box which is used for receiving electric energy output bythe power battery; a driving motor controller which is used for performing inversion voltage reduction on the high-voltage direct current output by the high-voltage distribution box and converting the high-voltage direct current into alternating current mains supply; and a control system which is used for controlling the driving motor controller to supply power to the outside when the hydrogen energy automobile is in a power-on and non-driving state. The driving motor controller has the advantages that by means of the rectifying and inverting capacity of existing hardware of the driving motorcontroller, high-voltage direct current can be converted into alternating current mains supply to be used by an external load, the whole vehicle can continuously and stably supply power to the outside, the power supply requirement of external equipment is met, and the application scene of a hydrogen fuel cell vehicle is expanded.
