The invention provides a hydrogen-electricity hybrid driving system and a mine truck, and relates to the technical field of hybrid automobiles, the system comprises a traction converter, a hybrid battery system and a traction motor; the traction converter is connected between the hybrid battery system and the traction motor. The traction converter comprises an inverter and two direct current-direct current converters which are connected in parallel, and the two direct current-direct current converters are electrically connected with the traction motor through the inverter. The hybrid battery system comprises a hydrogen fuel battery system and a power battery system, and the hydrogen fuel battery system and the power battery system are correspondingly connected with the direct current-direct current converters respectively. The method has the effects that the reaction time during starting and braking of the hydrogen-electricity hybrid mine truck is shortened, and the control precision is improved.
