With the gradual promotion of new energy heavy truck related products and the gradual expansion and maturity of the related ecology of the changing station,improving the use flexibility and maintenance convenience of the battery assembly and its vehicles and the changing station,and reducing the cost have become an important issue for the further expansion of the application and promotion range of the changing technology and related vehicles and ecological products.In this paper,the time-division multiplexing method of the high-voltage power transmission circuit of the battery assembly was developed to realize the functions of common main circuit,dual-use charging,integration of fast and slow charging,in-station charging and off-vehicle charging,and the feasibility of further design of the battery assembly was analyzed to reduce cost and improve compatibility and adaptability of working conditions.The research results show that these new technologies have a good matching application effect,which can reduce the dependence on equipment such as changing power stations,make up for the lack of charging pile resources,reduce the battery assembly's binding on vehicles,improve vehicle operation rate,reduce construction investment,and promote the promotion of electric replacement technology,which is of great significance for expanding electric replacement models and their ecosystem application scenarios and regional radiation capabilities.However,there are also some limitations that need to be improved in the future.
