Power-off method of hydrogen-electric power automobile, central controller, storage medium and product

The invention provides a power-off method of a hydrogen electric power automobile, a central controller, a storage medium and a product. The method applied to the central controller of the hydrogen electric vehicle comprises the following steps: monitoring the working states of a vehicle body system, a vehicle-mounted information system and a chassis system when a high-voltage system and a fuel cell system are electrified to obtain working state data; according to the working state data, detecting whether the whole vehicle has a fault for influencing the safety of the whole vehicle or not; under the condition that it is detected that the whole vehicle breaks down, the high-voltage system and the fuel cell system are controlled to be powered off; under the condition that it is detected that the whole vehicle does not break down, whether the active control condition of power-off shutdown is met or not is detected; and when it is detected that the active control condition is met, controlling the fuel cell system
