The invention is suitable for the technical field of intelligent automobiles, and provides a fault diagnosis method and device for a hydrogen storage system in a vehicle, terminal equipment and the vehicle. The method comprises the steps that the pressure value in a medium-pressure pipeline and the current use state of the hydrogen storage system are obtained; determining a currently required fault diagnosis strategy according to the current use state of the hydrogen storage system, wherein the hydrogen storage system corresponds to different fault diagnosis strategies in different use states; and finally, obtaining a fault diagnosis result of the hydrogen storage system according to the detected pressure value and the determined fault diagnosis strategy. Whether the hydrogen storage system breaks down or not can be timely and accurately detected according to the pressure value in the medium-pressure pipeline, normal use of the vehicle is guaranteed, and potential safety hazards caused by the hydrogen storage system fault of the vehicle are avoided; besides, the hydrogen storage system corresponds to different fault diagnosis strategies in different use states, and whether the hydrogen storage system breaks down or not can be more accurately determined according to the current use state and the pressure value of the hydrogen storage system.
