The invention discloses a hydrogen fuel cell automobile switch type energy management strategy which comprises the steps that operation parameters such as the speed, the accelerated speed, the instantaneous load power, the hydrogen storage amount and the battery electric quantity of an automobile are collected in real time through a sensor system, data are transmitted to an energy management system, and according to the instantaneous load requirement of the automobile, the energy management system is started. Dynamically adjusting the energy output of the hydrogen fuel cell, the super capacitor and the lithium battery; under the low-load working condition, the lithium battery is preferentially used for providing power, and the use frequency of the fuel battery is reduced; in a medium load, the fuel cell and the lithium battery work cooperatively; under a high-load or acceleration working condition, the fuel cell system performs full-power output, and meanwhile, the super capacitor provides instantaneous high-power output, so that the high-power requirement is met; by flexibly switching the energy modules, the use efficiency of the fuel cell is improved, the hydrogen consumption is reduced, the service life of the fuel cell is prolonged, and the dynamic response capability and the cruising ability of the vehicle are improved.
