Abstract

Battery packs with a large number of cells are becoming more and more prominent technology. Monitoring and controlling these packs is now a subject with increased importance. The proposed implemented system consists of only three switches per cell, allowing several types of connection between the cells. The battery management system relies on a distributed hierarchical architecture with n-1local controllers and a global controller. In the proposed algorithm the cells act as a single swarm functioning autonomously and depending on the parameters (voltage, current and temperature) of each cell of the pack. The hardware for each cell is explained and demonstrated. The results obtained both in simulation and in experimental tests show the excellent performance of the proposed methodology. Also, the charging approach based on the traditional multistage method exhibited an excellent performance on charging supercapacitors, concerning its efficiency, charging time and overvoltage protection.

动态储能系统的一种新方法

具有大量电池芯的电池组正成为越来越突出的技术。监测和控制这些群体现在是一个越来越重要的课题。提出的实现系统由每个单元仅三个交换机组成，允许单元之间的几种类型的连接。电池管理系统采用分布式分层结构，具有n-1个本地控制器和1个全局控制器。在提出的算法中，电池作为一个独立的群体，根据电池组中每个电池的参数(电压、电流和温度)自主运行。对每个单元的硬件进行了解释和演示。仿真和实验结果表明，该方法具有良好的性能。此外，基于传统多级充电方法的充电方式在超级电容器充电效率、充电时间和过压保护等方面都表现出优异的性能。
