Design and Simulation Analysis of Power assembly of Series Electric Vehicles

Today, with the deepening of economic globalization, the economic level of the people of the world is constantly improving, and the problems of energy shortage and environmental pollution are becoming more and more prominent. Hybrid vehicles, which appear as substitutes for traditional internal combustion engine vehicles, have gradually become the focus of research and development in the world today. This design, on the basis of the existing models, by retrofitting the generator, motor and battery pack, is converted it into a series hybrid bus, and the parameter design of the power assembly is completed by determining the corresponding parameter matching principle. Then the corresponding model is established in matlab, and the feasibility of the parameter design is verified based on the model’s power and fuel economy analysis.
