Research on parallel charging equalization technology for VRLA batteries

ZHENG Shuai;WANG Ya-wei;CHEN Cui-li;WANG Zhi-qiang;LI Guo-feng;School of Electrical Engineering, Dalian University of Technology;  
The necessity and feasibility of electric vehicle battery equalization technology were discussed and existing battery equalization strategies were summarized. On the basis of comparative analysis, the battery parallel charging equalization technology was innovatively put forward, which has simple control strategy, reliable performance and low cost. The comparison experiments of parallel charging and series discharging for different SOCs of five valve regulated lead?acid(VRLA) batteries were performed for three times by battery series-parallel conversion device which was designed especially. The results validate the feasibility of the parallel charging equalization technology,improving the equalization of batteries voltage and reducing the difference of internal characteristics between cells to extend the cycle life of series batteries.
