Abanini bezithuthi zombane (EV) kwihlabathi liphela bahlala bedibana nomcimbi ocaphukisayo: ukonakala ngequbuliso naxa isalathisi sebhetri sibonisa amandla aseleyo. Le ngxaki ibangelwa ikakhulu kukukhupha ibhetri ye-lithium-ion, umngcipheko onokuthi uthotywe ngokufanelekileyo yiNkqubo yoLawulo lweBattery ephezulu (BMS).
Idatha yeShishini ibonisa ukuba iNkqubo yoLawulo lweBattery eyilwe kakuhle inokwandisa ubomi bebhetri ye-lithium-ion ukuya kuthi ga kwi-30% kwaye inciphise ukuphulwa kwe-EV ehambelana nemiba yebhetri ngama-40%. Njengoko imfuno yezithuthi zombane kunye neenkqubo zokugcina amandla zikhula, indima ye-BMS iya isanda kakhulu. Ayiqinisekisi ukhuseleko lwebhetri kuphela kodwa ikwakhulisa ukusetyenziswa kwamandla, ukukhuthaza uphuhliso oluzinzileyo lweshishini lamandla amatsha ehlabathi.
Ipakethi yebhetri ye-lithium-ion iqulethe iintambo ezininzi zeeseli, kwaye ukuhambelana kwezi seli kubalulekile ekusebenzeni ngokubanzi. Xa iiseli zomntu ngamnye zikhula, ziphuhlisa ukuchasana okugqithisileyo kwangaphakathi, okanye zinonxibelelwano olubi, i-voltage yabo inokuhla ukuya kwinqanaba elibalulekileyo (ngokuqhelekileyo i-2.7V) ngokukhawuleza kunabanye ngexesha lokukhutshwa. Xa oku kwenzeka, i-BMS iya kubangela ukukhuselwa ngokugqithisileyo ngokukhawuleza, ukunqumla ukunikezelwa kwamandla ukukhusela umonakalo ongenakukwazi ukuguqulwa-nokuba i-voltage yebhetri iyonke isephezulu.
Ukugcinwa kwexesha elide, i-BMS yanamhlanje inikeza imodi yokulala elawulwayo, eyanciphisa ukusetyenziswa kwamandla kuphela kwi-1% yokusebenza okuqhelekileyo. Lo msebenzi uthintela ngokufanelekileyo ukuthotywa kwebhetri okubangelwa kukuphelelwa kwamandla angasebenziyo, umba oqhelekileyo owenza bufutshane ubomi bebhetri. Ukongezelela, i-BMS ephakamileyo isekela iindlela zokulawula ezininzi nge-software yekhompyutheni ephezulu, kubandakanywa nokulawulwa kokukhutshwa, ukukhutshwa kwentlawulo, kunye nokusebenza kokulala, ukubetha ibhalansi phakathi kokubeka iliso ngexesha langempela (njengokuxhunywa kweBluetooth) kunye nokugcinwa kwamandla aphantsi.
