Ukuphepha kanye nokulula kokuhlanza amafasitela aphezulu sekuyisikhathi eside kufezwa kalula ngamarobhothi okuhlanza amafasitela. Kodwa bambalwa abantu abaqaphelayo ukuthi ukusebenza okuzinzile kwale "ngcweti yokuhlanza ezindaweni eziphakeme" kuncike esicini esibonakala singabalulekile kodwa esibalulekile—isixhumi. Ngokuxhumanisa iphakethe lebhethri ne-Battery Management System (BMS) kunoma iyiphi ingxenye, ixazulula ngokuthula izingozi eziningi ezingaba khona ngesikhathi sokusebenza kwemishini, isebenza njengomvikeli ongabonakali wokusebenza okuthembekile kwamarobhothi okuhlanza amafasitela.
Kumarobhothi okuhlanza amafasitela, ibhethri lisebenza njengesizinda samandla, i-BMS isebenza njengobuchopho, kanti isixhumi sisebenza njengesikhungo sezinzwa esizixhumanisa ndawonye. Ukufaniswa okungalungile kwesixhumi ngeke kubangele ukuvalwa kwemishini kanye nokuphazamiseka kokuhlanza, kodwa kungaholela nasezingozini zokuphepha njengokushisa ngokweqile kwebhethri kanye nama-short circuits.
Uma kusetshenziswa ngendlela engokoqobo, i-Battery Management System (BMS) ivame ukubhekana nezinkinga ezintathu ezinkulu—futhi izixhumi ziyizihluthulelo zokuzixazulula. I-Amass yethule i-XLB16, eyenzelwe ngqo ukuhambisana ne-BMS. Ibhekana kahle nalezi zinselele ezibalulekile, okwenza kube yisisombululo esithandwayo embonini.
I. Izingozi Zokwehluleka Kokuxhumana Ngaphansi Kokudlidliza Nezindawo Ezinzima
Amarobhothi okuhlanza amafasitela asebenza ngokudlidliza okuvama kakhulu futhi abhekana nokushisa okuhlala kushintsha ngaphakathi nangaphandle kanye nomswakama ngokuhamba kwesikhathi. Lezi zimo zibangela kalula ukuthi izixhumi zikhulule, zixube, noma ziqongelele uthuli, okuholela ekumelaneni okukhulu kokuxhumana. Lokhu kuholela ekushajeni okungavamile, ukulahlekelwa amandla okungalindelekile ngesikhathi sokusebenza, kanye ne-voltage yeseli engaguquki.
Idizayini yebhakede eyakhelwe ngaphakathi, i-XLB16 imelana nokushaqeka kokudlidliza okuvamise kakhulu. Ihlanganiswe nama-conductor ethusi acwebezelayo acwebezelayo ngesiliva, igcina ukumelana kokuthinta ku-≤0.8mΩ ngenkathi igcina ukuxhumana okuzinzile ngaphansi kokudlidliza okuqhubekayo. Lokhu kuqeda ngokuphelele ukwehluleka kokuthinta futhi kuhlangabezana kahle nezidingo zokuxhumeka okuzinzile zezinhlelo zokuphatha ibhethri.
II. Inselele Yokulinganisela Phakathi Kokukhuphuka Kwezinga Lokushisa Nokusebenza Kahle
Ngesikhathi sokusebenza noma ukushaja amarobhothi okuhlanza amafasitela, izixhumi ezivamile zivame ukuguga ngenxa yokukhiqizwa kokushisa, okuphazamisa ukunemba kwesampula kanye nesivinini sokuphendula kokuvikela kwe-BMS.
Ngokwandisa izingxenye ze-terminal kanye nokwenza ngcono isakhiwo sangaphakathi, i-XLB16 ifinyelela ukudluliselwa kwamandla okumelana okuphansi kanye nokusebenza kahle kakhulu. Isakhiwo sayo se-crown spring siqinisekisa ukuhlangana okuzinzile. Ukwenyuka kwezinga lokushisa lokusebenza kulawulwa ngaphakathi kwama-55K, okwanelisa ngokuphelele izidingo zokukhishwa kwamandla zamabhethri ngenkathi kugwema izingozi zokuphepha ezibangelwa ukushisa ngokweqile, kulinganisela kokubili ukusebenza kanye nokuzinza.
III. Ukulinganisela Ubulula Nokuthembeka
Uhlelo lokuphatha amabhethri (i-BMS) ludinga ukuvikelwa okuphelele ekulweni nokusetshenziswa kwamandla aphezulu, ukungabi namandla aphezulu, ukudlula kwamandla kagesi, amasekethe amafushane, nezinye izingozi ezingaba khona. I-XLB16 ifinyelela ibhalansi efanele yokuphepha kanye nokulula. Ayigcini nje ngokuklama okuphelele kokuvikela ukuphepha kodwa futhi izuza izinzuzo ezincane nezilula ukuzihlanganisa zochungechunge lwe-XL. Njengoba ilingana nomunwe, ivumela ukufakwa nokuhlukaniswa okusheshayo, okwenza ifaneleke kakhulu ezimweni zohlelo lokusebenza lwe-BMS zamarobhothi okuhlanza amafasitela.
Njengoba amadivayisi ahlakaniphile afana namarobhothi okuhlanza amafasitela ethuthuka abe nesisindo esilula, impilo yebhethri ende, kanye nezindinganiso zokuphepha eziphakeme, izidingo zezixhumi ziyaqhubeka nokukhuphuka. Kusukela emandleni ahlanganisiwe kanye nokudluliswa kwesignali kuya ekuzivumelaniseni okuqinile kokumelana nemvelo kanye nokumelana nokudlidliza, izixhumi azisezona izingxenye zokuxhuma ezilula.
I-Amass izoqhubeka nokuletha ubuchwepheshe bokuxhuma obuzinzile, obuphephile, nobusebenza kahle ukuze kuvikelwe amadivayisi ahlakaniphile, okufaka umfudlana oqhubekayo "wamandla okuxhuma" entuthukweni eqhubekayo yale mboni.
