A Uhlelo Lokuphathwa Kwebhethri(I-BMS)ibalulekile kumabhethri anamuhla ashajwayo. I-BMS ibalulekile ezimotweni zikagesi (ama-EV) kanye nokugcinwa kwamandla.
Iqinisekisa ukuphepha kwebhethri, ukuhlala isikhathi eside, kanye nokusebenza kahle kakhulu. Isebenza namabhethri e-LiFePO4 kanye ne-NMC. Lesi sihloko sichaza indlela i-BMS ehlakaniphile ebhekana ngayo namaseli anephutha.
Ukutholwa Nokuqapha Amaphutha
Ukuthola amaseli anephutha kuyisinyathelo sokuqala ekuphathweni kwebhethri. I-BMS iqapha njalo amapharamitha abalulekile eseli ngalinye ephaketheni, okuhlanganisa:
·I-voltage:I-voltage yeseli ngalinye iyahlolwa ukuze kutholakale izimo ze-over-voltage noma ze-under-voltage. Lezi zinkinga zingabonisa ukuthi iseli linephutha noma liyaguga.
·Izinga lokushisa:Izinzwa zilandelela ukushisa okukhiqizwa yiseli ngayinye. Iseli elinephutha lingashisa kakhulu, okubangela ingozi yokwehluleka.
·Okwamanje:Ukugeleza kwamandla kagesi okungajwayelekile kungabonisa ama-short circuits noma ezinye izinkinga zikagesi.
·Ukumelana Kwangaphakathi:Ukwanda kokumelana kuvame ukubonisa ukuwohloka noma ukwehluleka.
Ngokuqapha ngokucophelela lezi zinhlaka, i-BMS ingasheshe ibone amaseli ahluka ebangeni elijwayelekile lokusebenza.
Ukuxilongwa Kwephutha Nokuzihlukanisa
Uma i-BMS isithole iseli elinephutha, yenza ukuxilongwa. Lokhu kusiza ekunqumeni ubukhulu bephutha kanye nomthelela walo eqoqweni lilonke. Amanye amaphutha angase abe mancane, adinga ukulungiswa kwesikhashana kuphela, kanti amanye makhulu futhi adinga isinyathelo esisheshayo.
Ungasebenzisa i-active balancer ochungechungeni lwe-BMS ngamaphutha amancane, njengokungalingani kwamandla amancane. Lobu buchwepheshe budlulisela amandla kusuka kumaseli aqinile kuya kwabuthakathaka. Ngokwenza lokhu, uhlelo lokuphatha ibhethri lugcina ukushaja okuzinzile kuwo wonke amaseli. Lokhu kunciphisa ukucindezeleka futhi kuwasize ukuthi ahlale isikhathi eside.
Ngezinkinga ezinkulu kakhulu, njengemijikelezo emifushane, i-BMS izohlukanisa iseli elinephutha. Lokhu kusho ukuyinqamula ohlelweni lokulethwa kwamandla. Lokhu kuhlukanisa kuvumela lonke iphakethe ukuthi lisebenze ngokuphephile. Kungaholela ekwehleni okuncane kwamandla.
Izinqubo Zokuphepha Nezindlela Zokuvikela
Onjiniyela baklama i-BMS ehlakaniphile enezici ezahlukahlukene zokuphepha ukuze baphathe amaseli anezinkinga. Lokhu kufaka phakathi:
·Ukuvikelwa kwe-over-voltage kanye ne-Under-voltage:Uma i-voltage yeseli idlula imikhawulo ephephile, i-BMS ikhawulela ukushaja noma ukukhipha. Ingase futhi inqamule iseli emthwalweni ukuze ivimbele umonakalo.
· Ukuphathwa Kokushisa:Uma kwenzeka ukushisa ngokweqile, i-BMS ingasebenzisa izinhlelo zokupholisa, njengeziphepheni, ukuze yehlise izinga lokushisa. Ezimweni ezimbi kakhulu, ingacima uhlelo lwebhethri. Lokhu kusiza ekuvimbeleni ukuphuma kokushisa, okuyisimo esiyingozi. Kulesi simo, iseli lishisa ngokushesha.
Ukuvikelwa Kwesiyingi Esifushane:Uma i-BMS ithola i-short circuit, inqamula amandla ngokushesha kulelo seli. Lokhu kusiza ukuvimbela umonakalo owengeziwe.
Ukuthuthukiswa Nokunakekelwa Kokusebenza
Ukuphatha amaseli anephutha akukhona nje ukuvimbela ukwehluleka. I-BMS iphinde ithuthukise ukusebenza. Ilinganisela umthwalo phakathi kwamaseli futhi iqaphe impilo yawo ngokuhamba kwesikhathi.
Uma uhlelo luphawula iseli njengelinephutha kodwa elingakabi yingozi, i-BMS inganciphisa umthwalo walo womsebenzi. Lokhu kwandisa impilo yebhethri ngenkathi kugcina iphakethe lisebenza.
Futhi kwezinye izinhlelo ezithuthukisiwe, i-BMS ehlakaniphile ingaxhumana namadivayisi angaphandle ukuze inikeze ulwazi lokuxilonga. Ingase iphakamise izenzo zokulungisa, njengokufaka esikhundleni amaseli anephutha, ukuqinisekisa ukuthi uhlelo lusebenza kahle.
