Ngenxa yokuthi umthamo webhethri, ukumelana kwangaphakathi, i-voltage namanye amanani epharamitha akuhambisani ngokuphelele, lo mehluko udala ukuthi ibhethri elinamandla amancane lishajwe kalula futhi lishajwe ngesikhathi sokushajwa, futhi umthamo webhethri omncane kakhulu uba mncane ngemva kokulimala, ungene emjikelezweni ononya. . Ukusebenza kwebhethri elilodwa kuthinta ngokuqondile izici zokushajwa nokukhipha ibhethri lonke kanye nokuncipha komthamo webhethri.Ukusebenza kwe-BMS ngaphandle kwebhalansi ingumqoqi wedatha, okungelona neze uhlelo lokuphatha.Umsebenzi wakamuva wokulinganisa osebenzayo we-BMS ungabona ubukhulu obukhulu ukulinganisa okuqhubekayo okwamanje okungu-5A. Dlulisela ibhethri elilodwa lamandla aphezulu kubhethri elilodwa elinamandla amancane, noma sebenzisa lonke iqembu lamandla ukuze ungeze ibhethri elilodwa eliphansi kakhulu. Phakathi nenqubo yokusebenzisa, amandla asabalaliswa kabusha ngesixhumanisi sokulondoloza amandla, ukuze ukuze uqinisekise ukuvumelana kwebhethri ngezinga elikhulu kakhulu, thuthukisa imayela lempilo yebhethri futhi ulibazise ukuguga kwebhethri.
