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.
