Isingeniso:
Amabhethri e-lithiumZiya ngokuya zithandwa kakhulu ezinhlotsheni ezahlukahlukene ngenxa yobuningi bazo bamandla aphezulu, ukuphila isikhathi eside, isisindo esincane kanye nezakhiwo ezinobungani nemvelo. Lo mkhuba usufinyelele nasezinqoleni zegalofu, lapho abakhiqizi abaningi ngokwengeziwe bekhetha amabhethri e-lithium ukuze bathathe indawo yamabhethri endabuko e-lead-acid. Kodwa-ke, ukukhathazeka okuvamile phakathi kwabanikazi bezinqola zegalofu ukuthi kungenzeka ukuthi amabhethri e-lithium ashajwe ngokweqile kanye nomthelela wawo ekusebenzeni kwawo nasekuphileni isikhathi eside.
Ukuqonda Ukushaja Ibhethri Le-Lithium
Ukuze kuxazululwe le nkinga, kubalulekile ukuqonda kuqala izisekelo zokushaja ibhethri le-lithium. Ngokungafani namabhethri e-lead-acid,amabhethri e-lithiumzidinga izinqubo ezithile zokushaja ukuqinisekisa ukusebenza kahle nokuphepha. Inqubo yokushaja ivame ukuhilela izigaba ezimbili: ugesi oqhubekayo (CC) kanye nogesi oqhubekayo (CV).
Ngesikhathi sesigaba samandla kagesi esingaguquki, ibhethri lishaja ngesivinini esizinzile kuze kube yilapho lifinyelela kumandla kagesi anqunyiwe. Uma leli mandla kagesi selifinyelelwe, ishaja ishintshela esigabeni samandla kagesi angaguquki, lapho amandla kagesi ehlala engaguquki kuyilapho amandla kagesi ehla kancane kancane. Le nqubo yokushaja enezigaba ezimbili yenzelwe ukukhulisa impilo yebhethri nokusebenza kwayo.
Ithonya Lokushaja Kakhulu
Ukushaja ngokweqile kwenzeka lapho i-voltage yokushaja yebhethri idlula izinga layo elinconywayo. Lokhu kungaholela ezinkingeni eziningi, okuhlanganisa impilo yebhethri emfushane, amandla ancishisiwe, futhi ezimweni ezimbi kakhulu, ukugijima okushisayo ngisho nomlilo. Uma kukhulunywa ngamabhethri enqola yegalofu, ukushaja ngokweqile kungathinta kakhulu ukusebenza okuphelele kanye nesikhathi sokuphila kwebhethri le-lithium-ion.
Enye yezinkinga ezinkulu ngokushaja ngokweqileamabhethri enqola yegalofu ye-lithiumukuthi impilo yomjikelezo ingancishiswa. Impilo yomjikelezo ibhekisela enanini lemijikelezo yokushaja ibhethri engadlula kuyo ngaphambi kokuba umthamo wayo wehle ngaphansi komkhawulo othile. Ukushaja ngokweqile kusheshisa ukuwohloka kwezinto ezisebenzayo zebhethri, okuholela ekuncishisweni kwesikhathi somjikelezo kanye nesikhathi sokuphila sonke.
Ngaphezu kokunciphisa impilo yomjikelezo, ukushaja ngokweqile kungabangela ukwanda kokumelana kwangaphakathi kwebhethri. Lokhu kungabangela amazinga okushisa aphezulu okusebenza, ukusebenza kahle kwamandla okuphansi, kanye nokusebenza okuphansi jikelele. Endabeni yezinqola zegalofu, le miphumela ingabangela ukwehla kwebanga lokushayela, ukwehla kokukhishwa kwamandla, futhi ekugcineni kube nokuhlangenwe nakho komsebenzisi okonakele.

Ukuvimbela Ukushaja Okungaphezu Kokulindelekile
Ukuze kuncishiswe ingozi yokushaja ngokweqile, abanikazi bezinqola zegalofu kanye nabaqhubi kumele basebenzise imikhuba efanele yokushaja futhi basebenzise amashaja aklanyelwe ngqo amabhethri e-lithium-ion. Lokhu kufaka phakathi ukusebenzisa ishaja efakwe izindlela zokulawula i-voltage kanye nogesi ukuze kuvinjelwe ukushaja ngokweqile, kanye nokunamathela kuphrothokholi yokushaja enconyiwe yomkhiqizi.
Ngesikhathi esifanayo, ukusebenzisauhlelo lokuphatha ibhethri (i-BMS)inganikeza isendlalelo esengeziwe sokuvikela ekushajeni ngokweqile nakwezinye izinkinga ezingaba khona. Izinhlelo ze-BMS zenzelwe ukuqapha nokulinganisela ama-voltage eseli ngalinye, ukuqinisekisa ukuthi amabhethri asebenza ngaphakathi kwemingcele ephephile futhi avimbele ukushaja ngokweqile noma ukushaja kancane kwamaseli athile.
Isiphetho
Ukushaja ngokweqileibhethri yenqola yegalofu ye-lithiumkungaba nemiphumela emibi ekusebenzeni kwayo, isikhathi sokuphila kwayo, kanye nokuphepha kwayo. Kubalulekile ukuqonda izidingo zokushaja zamabhethri e-lithium nokusebenzisa amashaja afanele kanye nezinqubo zokushaja ukuze kuvinjelwe ukushaja ngokweqile. Ukulandela iziqondiso zomkhiqizi, ukusebenzisa amashaja ahambisanayo, futhi, uma etholakala, ukuthembela kuzinhlelo zokuphatha amabhethri ezakhelwe ngaphakathi kungasiza ekuqinisekiseni ukuthi amabhethri enqola yegalofu ye-lithium ahlala isikhathi eside futhi aphephile. Ngokuthatha lezi zinyathelo zokuphepha, abanikazi benqola yegalofu bangajabulela izinzuzo zamabhethri e-lithium ngenkathi bekhulisa isikhathi sabo sokuphila futhi benciphisa izingozi ezingaba khona.
Uma unemibuzo noma ungathanda ukwazi okwengeziwe, sicela ungangabazi ukungithumelelaxhumana nathi.
