Therefore, it can be said that fuel cell vehicles are hydrogen-lithium hybrid vehicles. Since hybrid vehicles involve multiple power sources, how to dynamically distribute energy is very critical. Automotive electrical power matching refers to the power matching relationship between the automotive generator, battery, and electrical equipment in the vehicle. In this relationship, the generator is the output end of electrical energy, and the electrical equipment is the consumption end of electrical energy. The battery plays the role of supplying power to the starter and coordinating the relationship between the two, that is, assisting the generator to supply power to the electrical equipment and charging it with the output power of the generator. If the power matching is improper, it will seriously affect the operation of the generator, battery, and electrical equipment, and affect the user experience.
