Ker zmogljivost baterije, notranja upor, napetost in druge vrednosti parametrov niso popolnoma skladni, ta razlika povzroči, da se baterija med polnjenjem zlahka pretirava in izpusti, najmanjša zmogljivost baterije pa po poškodbi postane manjša, ko vstopi v začaran krog. The performance of single battery directly affects the charge and discharge characteristics of the whole battery and the reduction of battery capacity.BMS without balance function is just a data collector,which is hardly a management system.The latest BMS active equalization function can realize the maximum continuous 5A equalization current.Transfer the high-energy single battery to the low-energy single battery, or use the whole group of energy to supplement the lowest single battery.During the implementation process,the energy is redistributed through the Povezava za shranjevanje energije, da se zagotovi doslednost baterije v največji meri, izboljšate kilometrino v življenjski kilometri in odložite staranje baterije.
