Summary:With the continuous development of the industrialization of electric vehicles, how to efficiently use the energy storage value of the vehicle battery has become a hot research direction. Based on the analysis of the trip characteristics of electric vehicles and the capacity of traditional batteries, this paper proposes that the power-changing mode with small capacity can well match the characteristics of the majority of users' short and medium trips. Therefore, a mobile modular sharing design is adopted for on-board batteries. Further, the working mode and total capacity of the proposed Centralized Battery management System (CBMS) are designed, taking into account the difference of travel time and the influence of battery charging mode. Finally, the design of battery management system is analyzed and illustrated by taking a small district as an example. The results show that the proposed battery management model can promote the absorption of photovoltaic and reduce the average cost of on-board batteries, providing reference for the development of electric vehicle industry.
