Optimization the fast charging parameters of VRLA battery based on Mas laws
Mas laws followed during value-regulated lead-acid(VRLA)battery charging are analyzed.A fast charging method is proposed with adding negative pulse discharge depolarization in the charging process to reduce the over potential,which not only improves the initial charging acceptable current of the battery,but also improves the acceptable rate of charging.The pulse fast charging circuit for VRLA batteries below 12 V/20 Ah is fabricated,and the specific charging stage and optimized charging parameters are determined through multiple charging experiments.VRLA battery pulse fast charging circuit through the first stage of larger constant current charging in a short time as far as possible into more power,the second stage of optimizing charging parameters of pulse cycle fast charging can reduce the battery concentration polarization,charging efficiency is greatly improved,thus achieving the purpose of fast,lossless charging.
