Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of hydrogen engines, in particular to the technical field of a hydrogen engine and a novel energy output management method thereof.
[ background of the invention ]
The hydrogen engine is a new power source which utilizes the electrochemical reaction of hydrogen and oxygen to generate electricity. Compared with the traditional fuel oil automobile, the new energy automobile adopting the novel power can realize zero emission and has extremely low environmental pollution in the whole life cycle; compared with a pure electric vehicle, the electric vehicle has no inherent defects such as endurance mileage limitation and the like. Therefore, the hydrogen engine has become an important development direction of new energy automobiles in the future.
Although the hydrogen engine has the advantages of energy conservation and environmental protection compared with the traditional internal combustion engine, the hydrogen engine cannot rapidly cut off the electric energy output of the electric pile at working points of idle running or emergency braking of a vehicle and the like the traditional internal combustion engine due to certain effective working area and working inertia of the electrochemical reaction of the hydrogen and the oxygen, so that zero energy output to an external system is realized.
At present, the existing hydrogen engine technology rarely considers the energy management strategy at this special moment, and generally adopts the control of the SOC state of the lithium ion battery used in cooperation with the hydrogen engine, so as to avoid the situation that the energy output of the hydrogen engine cannot be accepted in the whole vehicle as much as possible. The future development trend of hydrogen engine vehicles is the gradual decline of the energy ratio of lithium ion batteries. When the automobile runs at idle speed or is braked emergently, if the hydrogen engine cannot cut off the output of external energy rapidly, the SOC of the lithium ion battery is too high. This results in: 1) the utilization rate of the lithium ion battery is not high, so that waste is caused; 2) the hydrogen engine is forced to be shut down due to the overhigh SOC, and needs to be restarted again when the vehicle runs again, so that the hydrogen engine is frequently turned on and turned off, and the service life of the hydrogen engine is influenced; 3) if the hydrogen engine is not shut down, only extremely low energy output can be maintained, at the moment, the working current of the hydrogen engine is small, the working voltage is extremely high compared with the normal working voltage, the DCDC matched with the hydrogen engine and the corresponding electric component working area are required to be very wide, and the working efficiency of the system is greatly reduced.
