Njengoko ukwamkelwa kwezithuthi zombane (ii-EV) kwihlabathi liphela kunye nokugcinwa kwamandla avuselelekayo kukhawuleziswa, ixesha elide leebhetri ze-lithium-ion liye laba yingxaki ephambili. Eyona nto iphambili kulo mba kuxhomekeke kubuchwepheshe obubalulekileyo ngaphakathiInkqubo yoLawulo lweeBhetri (i-BMS)eyaziwa ngokuba kukulinganisela iiseliLe nkqubo ibalulekile ekusoyiseni "isiphumo semigqomo," apho iseli ebuthathaka kakhulu ithintela ukusebenza kwephakheji yonke.
Isizathu Sokuba Kukho Ukungalingani KwebhetriEkuhambeni kwexesha, iiseli nganye nganye ngaphakathi kwebhetri zikhula ngokungaguqukiyo ngenxa yokunyamezelana kokwenziwa, ukusasazwa kobushushu obungalinganiyo, okanye ukwaluphala. Ngaphandle kokungenelela, iseli enye enomthamo ophantsi okanye ukumelana okuphezulu kwangaphakathi iya kufikelela kumda wayo wevolthi ngaphambi kwezinye ngexesha lokutshaja. Oku kunyanzela i-Ibhodi yokukhusela i-BMSukucima umbane ngaphambi kwexesha, nto leyo eshiya yonke ipakethi itshajiwe ngokwaneleyo kwaye kunciphisa kakhulu amandla asetyenziswayo.
Ukulinganisela okusebenzayo kunye nokungashukumiyo: Ukuqonda umahlukoUkulwa nale nto, yanamhlanjeizisombululo ze-BMS ezikrelekrelesebenzisa amaqhinga amabini aphambili:
Ukulinganisela Okungasebenziyo:Le ndlela isebenzisa izithinteli ukukhupha amandla agqithisileyo kwiiseli ezine-voltage ephezulu njengobushushu, nto leyo evumela iiseli ezine-voltage ephantsi ukuba zifikelele. Ingabizi kakhulu kwaye ifanelekile kwizicelo zamandla aphantsi kodwa ayisebenzi kakuhle kwiibhanki ezinkulu.
Ukulinganisela Okusebenzayo:Eli likamva leukulinganiswa kwebhetri ye-lithiumEndaweni yokuchitha amandla, ii-balancer ezisebenzayo zisebenzisa ii-capacitors okanye ii-inductors ukuhambisa amandla ukusuka kwiiseli ezine-voltage ephezulu ukuya kwezo zine-voltage ephantsi. Olu dluliselo lwamandla luphucula ukusebenza kakuhle kwaye lubalulekile kumandla aphezulu.Iipakethi zebhetri zeLiFePO4isetyenziswa ekugcinweni kwamandla elanga.
Impembelelo kuBomi boMjikelo
Ukulinganisela iiseli okusebenzayo kwenza okungaphezulu kokubuyisela amandla kuphela; kwandisa ubomi bomjikelo webhetri. Ngokugcina umahluko wevolthi ($V_{diff}$) ubuncinci (ngokuqhelekileyo ngaphakathi kwe-30mV okanye i-5mV),Inkqubo yoLawulo lweBhetriithintela iiseli zomntu ngamnye ekubeni zixinezeleke kakhulu.
Kubathengi kunye nabadibanisi bemizi-mveliso ngokufanayo, ukukhetha i-BMS enobuchule bokulinganisela obuphezulu—nokuba buyasebenza okanye abusebenzi—yeyona ndlela isebenzayo yokukhusela utyalo-mali lwabo. Njengoko itekhnoloji itshintsha, ukulinganisela okusebenzayo okunamandla aphezulu kumisela umgangatho omtsha wolawulo lwamandla oluzinzileyo.
