针对现有电动汽车电池管理系统（BMS）布线复杂的问题,提出了一种新型BMS。该系统基于一种功率/信号时分复用总线,极大地减少了单体电池采样、均衡和通信的线束,简化了电池箱内的布线和结构设计,提高了系统的可靠性。在应用复用总线的基础上,设计了一种针对单体电池的控制器。该单体电池控制器实现了模块化设计,降低了整体系统的设计和配置的复杂性,同时存储电池历史信息等,便于电池的二次使用。详细介绍了该功率/信号时分复用总线的设计和控制方法,分析了影响总线性能的因素。最后通过Matlab仿真验证了该BMS理论设计的正确性,并通过实验验证了该BMS的可行性。

英文摘要：

To solve the wiring problems in the existing electric vehicle（EV） battery management system（BMS）, this paper presents a new architectural design of BMS.The design is based on a power/signal time division multiplexing bus, which greatly reduces the unit cell sampling, balance and communication strings, simplifies wiring and structural design of the battery box,and improves the reliability of the system.Based on the multiplexing bus,a cell controller is designed.The single cell controller implements a modular design that reduces overall system design and configuration complexity.Meanwhile, it records battery history information to facilitate the reutilization of battery.This paper describes the design and control method of time-division multiplexing signal bus, and analyzes the factors affecting the performance of the bus.Finally, Matlab simulation and experiments of this BMS are performed to verify the validity and feasibility of the design.
