Isingeniso:
Eminyakeni yakamuva,amabhethri e-lithiumbathole ukudonsa okubalulekile njengomthombo wamandla okhethwayo wezinqola zegalofu, ukudlula amabhethri endabuko e-lead-acid ekusebenzeni nokuphila isikhathi eside. Ukuminyana kwazo okuphakeme, isisindo esilula, nokuphila isikhathi eside kubenza babe ukukhetha okukhangayo kubadlali begalofu nabaqhubi bezinqola ngokufanayo. Kodwa-ke, ukuze usebenzise ngokugcwele izinzuzo zamabhethri e-lithium, kubalulekile ukuqonda nokuhambisana nezimo ezifanele zokushaja. Lesi sihloko sidingida izimo ezibalulekile zokushaja amabhethri e-lithium ezinqoleni zegalofu, iqinisekisa ukusebenza kahle nokuphila isikhathi eside.
Amabhethri e-lithium, ikakhulukazi i-Lithium Iron Phosphate (LiFePO4), avame ukusetshenziswa ezinqoleni zegalofu ngenxa yokuphepha nokusebenza kahle kwawo. Ngokungafani namabhethri e-lead-acid, adinga ukuchelelwa ngezikhathi ezithile futhi anephrofayili yokushaja eyinkimbinkimbi, amabhethri e-lithium ahlinzeka ngohlelo lokulungisa olulula. Ngokuvamile zifaka Amasistimu Okulawula Ibhethri (BMS) akhelwe ngaphakathi aqapha futhi alawule ukushaja, ukushajwa, kanye nempilo yonke.
Izinga Lokushisa Elilungile Lokushaja
Izinga lokushisa lidlala indima ebalulekile ohlelweni lokushajaamabhethri e-lithium. Ukuze usebenze kahle nokuphepha, amabhethri e-lithium kufanele ashajwe ngaphakathi kwebanga lokushisa elithile. Ngokuvamile, izinga lokushisa elinconywayo lokushaja lamabhethri amaningi e-lithium liphakathi kuka-0°C (32°F) no-45°C (113°F). Ukushaja ngaphandle kwalolu banga kungaholela ekwehleni ukusebenza kahle kanye nokulimala okungaba khona ebhethrini.
Amazinga Okushisa Okubandayo:Ukushaja amabhethri e-lithium ezimeni ezibanda kakhulu (ngaphansi kuka-0°C) kungaholela ekufakweni kwe-lithium kuma-electrode ebhethri, okungase kwehlise umthamo nempilo yokuphila. Kutuswa ukuthi uqinisekise ukuthi ibhethri liyafudumala okungenani libe ngu-0°C ngaphambi kokuqala ukushaja.
Amazinga Okushisa Aphezulu:Ukushaja emazingeni okushisa angaphezu kuka-45°C kungabangela ukushisa ngokweqile, okungaba nomthelela omubi empilweni yebhethri nokusebenza kwayo. Kubalulekile ukuqinisekisa ukungena komoya okufanele futhi ugweme ukushaja ibhethri elangeni eliqondile noma eduze nemithombo yokushisa.
Isisetshenziswa esifanele sokushaja
Ukusebenzisa ishaja efanele kubalulekile empilweni yeamabhethri e-lithium. Ishaja edizayinelwe ngokuqondile amabhethri e-lithium izoba nephrofayela efanele yokushaja, okuhlanganisa ugesi olungile kanye nemikhawulo yamanje. Kubalulekile ukusebenzisa amashaja anconywe umkhiqizi webhethri ukugwema ukushajwa ngokweqile noma ukushajwa okungaphansi, kokubili okungalimaza ibhethri.
Ukuhambelana kwe-Voltage:Qinisekisa ukuthi i-voltage ephumayo yeshaja ihambisana nezidingo zebhethri. Isibonelo, ibhethri ye-lithium engu-12V ngokuvamile idinga ishaja enokukhipha okungu-14.4V kuya ku-14.6V.
Umkhawulo Wamanje:Amashaja kufanele abe namandla okukhawulela ukushaja ngokuya ngokucaciswa kwebhethri. Ukushaja ngokweqile kwamandla kungaholela ekushiseni ngokweqile nasezingozini zokuphepha ezingaba khona.
Isikhathi sokushaja kanye nemijikelezo
Ngokungafani namabhethri e-lead-acid, amabhethri e-lithium awadingi ukushajwa ngokugcwele ngaphambi kokushajwa kabusha. Eqinisweni, ukukhishwa okuyingxenye kaningi kunenzuzo kumabhethri e-lithium. Nokho, kubalulekile ukulandela izincomo zomkhiqizi mayelana nezikhathi zokushaja nemijikelezo.
Ukushaja Ingxenye: Amabhethri e-lithiumangashajwa noma nini, futhi ngokuvamile kungcono ukuwagcina egcwele kunokuwayeka aphume aphele. Lo mkhuba unomthelela esikhathini eside sempilo nokusebenza okungcono.
Imijikelezo yokushaja egcwele:Nakuba amabhethri e-lithium edizayinelwe ukuphatha inombolo ebalulekile yemijikelezo yokushaja, ukuwakhipha njalo ukuya kumazinga aphansi kakhulu ngaphambi kokushaja kunganciphisa ukuphila kwawo. Khomba ukushaja ingxenye futhi ugweme ukukhipha okujulile ukuze ukhulise impilo yebhethri.
Isiphetho
Amabhethri e-lithiumzimelela intuthuko enkulu kubuchwepheshe bekalishi yegalofu, enikeza ukusebenza okuthuthukisiwe nokuphila isikhathi eside. Ngokunamathela ezimisweni zokushaja ezinconyiwe—ukugcina amazinga okushisa afanele, ukusebenzisa ishaja efanele, nokulandela izinqubo ezingcono kakhulu zokushaja nokunakekela—ungaqinisekisa ukuthi ibhethri lakho le-lithium lihlala lisesimweni esifanele. Ukwamukela le mihlahlandlela akugcini nje ngokunweba impilo yebhethri lakho kodwa futhi kuthuthukisa ukusebenza kahle okuphelele nokuthembeka kwekalishi lakho legalofu, okwenza yonke imizuliswano yegalofu ibe yinto ejabulisa kakhudlwana.
