A Uhlelo Lokuphatha Ibhethri(BMS)ibalulekile kumaphakethe ebhethri ashajwayo esimanje. I-BMS ibalulekile ezimotweni zikagesi (EVs) kanye nokugcinwa kwamandla.
Iqinisekisa ukuphepha kwebhethri, ukuphila isikhathi eside, nokusebenza okuphelele. Isebenza ngawo womabili amabhethri e-LiFePO4 ne-NMC. Lesi sihloko sichaza ukuthi i-BMS ehlakaniphile isebenza kanjani namaseli angalungile.
Ukutholwa Kwephutha Nokuqapha
Ukuthola amaseli angalungile kuyisinyathelo sokuqala sokuphathwa kwebhethri. I-BMS ihlale iqapha amapharamitha abalulekile eseli ngalinye ephaketheni, okuhlanganisa:
·Amandla kagesi:Amandla kagesi eseli ngalinye ayahlolwa ukuze kutholwe izimo ze-over-voltage noma ngaphansi kwe-voltage. Lezi zinkinga zingabonisa ukuthi iseli linephutha noma liyaguga.
·Izinga lokushisa:Izinzwa zilandelela ukushisa okukhiqizwa iseli ngayinye. Iseli elingalungile lingase lishise ngokweqile, lidale ingozi yokwehluleka.
·Okwamanje:Ukugeleza kwamanje okungavamile kungase kubonise amasekhethi amafushane noma ezinye izinkinga zikagesi.
·Ukumelana Kwangaphakathi:Ukwenyuka kokumelana ngokuvamile kubonisa ukuwohloka noma ukwehluleka.
Ngokuqapha ngokucophelela le mingcele, i-BMS ingakwazi ukubona ngokushesha amaseli aphambuka kububanzi obujwayelekile bokusebenza.
Ukuxilongwa Kwephutha Nokuhlukaniswa
Uma i-BMS ithola ingqamuzana elinephutha, yenza ukuxilonga. Lokhu kusiza ukunquma ubukhali bephutha kanye nomthelela walo kuphakethe lilonke. Amanye amaphutha angase abe mancane, adinga ukulungiswa kwesikhashana kuphela, kuyilapho amanye enzima futhi edinga isinyathelo esisheshayo.
Ungasebenzisa ibhalansi esebenzayo ochungechungeni lwe-BMS ngamaphutha amancane, njengokungalingani okuncane kwamandla kagesi. Lobu buchwepheshe buhambisa kabusha amandla ukusuka kumaseli anamandla kuye kwabuthaka. Ngokwenza lokhu, isistimu yokuphatha ibhethri igcina ukushajwa okuqinile kuwo wonke amaseli. Lokhu kunciphisa ukucindezeleka futhi kuzisiza ukuthi zihlale isikhathi eside.
Ngezinkinga ezinzima kakhulu, njengamasekhethi amafushane, i-BMS izohlukanisa iseli elingalungile. Lokhu kusho ukuyinqamula ohlelweni lokulethwa kwamandla. Lokhu kuhlukaniswa kuvumela lonke iphakethe ukuthi lisebenze ngokuphepha. Kungase kuholele ekwehleni okuncane komthamo.
Izinqubo Zokuphepha kanye Nezindlela Zokuvikela
Onjiniyela baklama i-BMS ehlakaniphile enezici ezihlukahlukene zokuphepha ukuze balawule amaseli anamaphutha. Lokhu kubandakanya:
·I-Over-voltage kanye ne-Under-voltage Protection:Uma i-voltage yeseli yeqa imikhawulo ephephile, i-BMS ikhawulela ukushaja noma ukushajwa. Ingase futhi inqamule iseli ekulayisheni ukuvimbela umonakalo.
· Ukuphatha Okushisayo:Uma ukushisa ngokweqile kwenzeka, i-BMS ingavula amasistimu okupholisa, njengamafeni, ukuze ehlise izinga lokushisa. Ezimweni ezimbi kakhulu, ingase ivale isistimu yebhethri. Lokhu kusiza ukuvimbela ukubaleka okushisayo, okuyisimo esiyingozi. Kulesi simo, ingqamuzana lishisa ngokushesha.
Ukuvikelwa Kwesifunda Esifushane:Uma i-BMS ithola isiyingi esifushane, inqamula amandla kuleyo cell ngokushesha. Lokhu kusiza ukuvimbela umonakalo owengeziwe.
Ukuthuthukiswa Kokusebenza Nokugcina
Ukuphatha amaseli anamaphutha akukhona nje ukuvimbela ukwehluleka. I-BMS iphinde ithuthukise ukusebenza. Ilinganisa umthwalo phakathi kwamaseli futhi iqaphe impilo yabo ngokuhamba kwesikhathi.
Uma isistimu imaka iseli njengenephutha kodwa elingakabi yingozi, i-BMS ingase yehlise umsebenzi wayo. Lokhu kunweba impilo yebhethri ngenkathi kugcinwa iphekhi isebenza.
Futhi kwezinye izinhlelo ezithuthukile, i-BMS ehlakaniphile ingaxhumana namadivayisi angaphandle ukuze anikeze ulwazi lokuxilonga. Ingase iphakamise izenzo zokulungisa, njengokushintsha amaseli angalungile, ukuqinisekisa ukuthi isistimu isebenza kahle.
