Emhlabeni okhula ngokushesha wamabhethri, i-Lithium Iron Phosphate (LFP) izuze amandla amakhulu ngenxa yephrofayili yayo yokuphepha enhle kakhulu nempilo yomjikelezo omude. Nokho, ukuphatha le mithombo yamandla ngokuphepha kuhlala kubalulekile. Enhliziyweni yalokhu kuphepha kukhona i-Battery Management System, noma i-BMS. Le nqubo yokuvikela eyinkimbinkimbi idlala indima ebalulekile, ikakhulukazi ekuvimbeleni izimo ezimbili ezingase zibe yingozi futhi zibe yingozi: ukuvikela ukushajwa ngokweqile kanye nokuvikela ukuchithwa ngokweqile. Ukuqonda lezi zindlela zokuphepha kwebhethri kuyisihluthulelo kunoma ubani othembele kubuchwepheshe be-LFP ukuze alondoloze amandla, kungakhathaliseki ukuthi kusesetuthini yasekhaya noma amasistimu ebhethri amakhulu ezimbonini.
Kungani Ukuvikelwa Kwe-Over Charge Kubalulekile Kumabhethri e-LFP
Ukushajwa ngokweqile kwenzeka lapho ibhethri liqhubeka nokuthola amandla angaphezu kwesimo salo sokushajwa ngokugcwele. Ngamabhethri e-LFP, lokhu kungaphezu nje kwenkinga yokusebenza kahle—kuyingozi yokuphepha. I-voltage eningi ngesikhathi sokushajwa ngokweqile ingaholela kulokhu:
- Ukukhuphuka kwezinga lokushisa ngokushesha: Lokhu kusheshisa ukuwohloka futhi, ezimweni ezimbi kakhulu, kungase kuqalise ukubaleka okushisayo.
- Ukwakhiwa kwengcindezi yangaphakathi: Ukubangela ukuvuza okungaba khona kwe-electrolyte noma ngisho nokukhipha umoya.
- Ukulahlekelwa kwamandla okungabuyiseleki emuva: Kulimaza ukwakheka kwangaphakathi kwebhethri futhi kufinyeze ubude bempilo yebhethri.
I-BMS ilwa nalokhu ngokuqapha okuqhubekayo kwamandla kagesi. Ilandelela ngokunembile i-voltage yeseli ngayinye ngaphakathi kwephekhi isebenzisa izinzwa ezingaphakathi. Uma noma iyiphi i-voltage yeseli ikhuphuka idlule umkhawulo ophephile onqunywe kusengaphambili, i-BMS ithatha isinyathelo ngokushesha ngokuyala ukunqanyulwa kwesekhethi yokushaja. Lokhu kunqanyulwa ngokushesha kwamandla okushaja kuyisivikelo esiyinhloko ekushajweni ngokweqile, ukuvimbela ukwehluleka okuyinhlekelele. Ukwengeza, izixazululo ze-BMS ezithuthukisiwe zifaka ama-algorithms ukuphatha izigaba zokushaja ngokuphepha.
Iqhaza Elibalulekile Lokuvimbela Ukukhipha Okungaphezu Kokuphuma
Ngokuphambene, ukushajwa kwebhethri ngokujule kakhulu—ngaphansi kwephoyinti elinconyiwe lokunqamuka kwamandla kagesi— nakho kubangela izingozi ezinkulu. Ukukhishwa okujulile kwamabhethri e-LFP kungabangela:
- Umthamo omkhulu uyafiphala: Ikhono lokubamba ukushaja okuphelele liyancipha kakhulu.
- Ukungaqini kwamakhemikhali kwangaphakathi: Ukwenza ibhethri lingaphephile ukushajwa kabusha noma ukusetshenziswa esikhathini esizayo.
- Ukuguqulwa kwamaseli okungenzeka: Kumaphakethe anamaseli amaningi, amaseli abuthaka angaqhutshwa abuyele emuva, abangele ukulimala okungapheli.
Lapha, i-BMS isebenza njengomnakekeli oqaphile futhi, ngokuyinhloko ngokuqapha okunembile kwesimo sokushaja (i-SOC) noma ukutholwa kwe-voltage ephansi. Ilandelela eduze amandla atholakalayo ebhethri. Njengoba ileveli kagesi yanoma iyiphi iseli isondela kumkhawulo obalulekile we-low-voltage, i-BMS iqala ukunqanyulwa kwesekethe yokukhipha. Lokhu kumisa ngokushesha ukudonsa kwamandla ebhethri. Ezinye izakhiwo eziyinkimbinkimbi ze-BMS ziphinde zisebenzisa amasu okucisha ukulayisha, ukwehlisa ngobuhlakani ukudonswa kwamandla okungabalulekile noma ukungena kumodi yamandla aphansi webhethri, ukwelula ukusebenza okubalulekile okuncane nokuvikela amaseli. Lo mshini wokuvimbela ukukhishwa okujulileubalulekile ekwandiseni impilo yomjikelezo webhethri nokugcina ukwethembeka kwesistimu iyonke.
Ukuvikela Okudidiyelwe: Ingqikithi Yokuphepha Kwebhethri
Ukuvikela ukushajwa ngokweqile nokukhishwa ngokweqile akuwona umsebenzi owodwa kodwa isu elihlanganisiwe ngaphakathi kwe-BMS eqinile. Amasistimu okuphatha amabhethri esimanje ahlanganisa ukucubungula kwesivinini esikhulu nama-algorithms ayinkimbinkimbi we-real-time voltage kanye nokulandelela kwamanje, ukuqapha izinga lokushisa, nokulawula okuguquguqukayo. Le ndlela yokuphepha kwebhethri ephelele iqinisekisa ukutholwa ngokushesha kanye nesinyathelo esisheshayo ngokumelene nezimo ezingaba yingozi. Ukuvikela ukutshalwa kwezimali kwebhethri lakho kuncike kulawa masistimu okuphatha ahlakaniphile.
