Ukubaluleka Kokuhlola Ibhethri Ukuphepha kanye nokusebenza Kwemikhiqizo Nezimoto

Amabhethri awumthombo wamandla oyinhloko wemikhiqizo, engashayela amadivaysi ukuthi asebenze.Ukuhlolwa okuningiliziwe kwamabhethri kusetshenziswa amathuluzi okuhlola kungaqinisekisa ukuphepha kwamabhethri futhi kuvimbele izimo ezifana nokuzithungela nokuqhuma ngenxa yamazinga okushisa aphezulu.Izimoto ziyindlela yethu yokuthutha eyinhloko futhi zisetshenziswa njalo, ngakho-ke kuyadingeka ukuhlola amabhethri ukuze kuqinisekiswe ukuphepha kwabashayeli.Indlela yokuhlola ilingisa izimo zezingozi ezihlukahlukene ukuze kunqunywe ukuthi ikhwalithi yebhethri ifanelekile futhi ibheke ukuthi ibhethri izoqhuma yini.Ngokusebenzisa lezi zivivinyo, izingozi zingagwenywa ngempumelelo futhi ukuzinza kungagcinwa.

1. Ukuphila Komjikelezo

Inombolo yemijikelezo yebhethri ye-lithium ibonisa ukuthi ibhethri ingashajwa kangaki futhi ishajwe ngokuphindaphindiwe.Kuye ngendawo lapho ibhethri ye-lithium isetshenziswa khona, impilo yomjikelezo ingahlolwa ukuze kunqunywe ukusebenza kwayo emazingeni okushisa aphansi, azungezile, naphezulu.Ngokuvamile, indlela yokulahla ibhethri ikhethwa ngokusekelwe ekusebenziseni kwayo.Kumabhethri amandla (njengezimoto zikagesi nama-forklifts), izinga lokugcinwa kwamandla okukhipha lika-80% livame ukusetshenziswa njengezinga lokulahlwa, kuyilapho ukugcina amandla namabhethri okugcina, izinga lokugcinwa kwamandla okukhipha lingaxegiswa libe ngu-60%.Kumabhethri esivame ukuhlangana nawo, uma umthamo wokushajwa/umthamo wokuqala okhishiwe ungaphansi kuka-60%, akufanele uwasebenzise njengoba engeke ahlale isikhathi eside.

2. Ikhono lokukala

Namuhla, amabhethri e-lithium awasetshenziswa kuphela emikhiqizweni ye-3C kodwa futhi aya ngokuya asetshenziswa ezinhlelweni zebhethri lamandla.Izimoto zikagesi zidinga ukushintsha kwemisinga ngaphansi kwezimo zokusebenza ezihlukene, futhi isidingo sokushaja okusheshayo kwamabhethri e-lithium siyanda ngenxa yokushoda kweziteshi zokushaja.Ngakho-ke, kuyadingeka ukuhlola amandla wezinga lamabhethri e-lithium.Ukuhlola kungenziwa ngokuvumelana namazinga kazwelonke amabhethri kagesi.Namuhla, abakhiqizi bamabhethri ngaphakathi nakwamanye amazwe bakhiqiza amabhethri akhethekile anezinga eliphezulu ukuze ahlangabezane nezidingo zemakethe.Ukuklanywa kwamabhethri anezinga eliphezulu kungasondezwa kumbono wezinhlobo zezinto ezisebenzayo, ukuminyana kwe-electrode, ukuminyana kokuqina, ukukhetha amathebhu, inqubo yokushisela, nenqubo yokuhlanganisa.Abanentshisekelo bangathola okwengeziwe ngayo.

3. Ukuhlola Ukuphepha

Ukuphepha kuyinkinga enkulu kubasebenzisi bebhethri.Izehlakalo ezinjengokuqhuma kwebhethri lefoni noma umlilo ezimotweni zikagesi zingasabisa.Ukuphepha kwamabhethri e-lithium kufanele kuhlolwe.Ukuhlola ukuphepha kufaka phakathi ukushaja ngokweqile, ukushajwa ngokweqile, ukujikeleza okufushane, ukuwa phansi, ukufudumeza, ukudlidliza, ukuminyanisa, ukubhoboza, nokuningi.Kodwa-ke, ngokombono wemboni yebhethri ye-lithium, lezi zivivinyo zokuphepha ziyizivivinyo zokuphepha, okusho ukuthi amabhethri avezwa izici zangaphandle ngenhloso ukuhlola ukuphepha kwawo.Idizayini yebhethri nemojuli idinga ukulungiswa ngokufanele ukuze kuhlolwe ukuphepha, kodwa ekusebenziseni kwangempela, njengalapho imoto kagesi ishayisa enye imoto noma into, ukushayisana okungavamile kungase kuveze izimo eziyinkimbinkimbi kakhulu.Kodwa-ke, lolu hlobo lokuhlola lubiza kakhulu, ngakho okuqukethwe kokuhlola okuthembekile kudinga ukukhethwa.

4. Ukukhipha Emazingeni Okushisa Aphansi Naphezulu

Izinga lokushisa lithinta ngokuqondile ukusebenza kokukhipha kwebhethri, okuboniswa kumthamo wokukhipha kanye ne-voltage yokukhipha.Njengoba izinga lokushisa lincipha, ukumelana kwangaphakathi kwebhethri kuyanda, ukusabela kwe-electrochemical kunciphisa, ukumelana ne-polarization kukhula ngokushesha, futhi umthamo wokukhipha ibhethri kanye nesiteji se-voltage siyancipha, okuthinta amandla namandla okukhipha.

Ngamabhethri e-lithium-ion, umthamo wokukhipha uyancipha kakhulu ngaphansi kwezimo eziphansi zokushisa, kodwa umthamo wokukhipha ngaphansi kwezimo zokushisa eziphezulu awukho ngaphansi kwalokho ekushiseni okuzungezile;ngezinye izikhathi, ingase ibe ngaphezudlwana komthamo ezingeni lokushisa elizungezile.Lokhu kubangelwa ikakhulukazi ukufuduka okusheshayo kwe-lithium ion emazingeni okushisa aphezulu kanye neqiniso lokuthi i-lithium electrode, ngokungafani ne-nickel ne-hydrogen storage electrode, ayiboli noma ikhiqize igesi ye-hydrogen ukuze inciphise umthamo emazingeni okushisa aphezulu.Uma ukhipha amamojula ebhethri emazingeni okushisa aphansi, ukushisa kukhiqizwa ngenxa yokumelana nezinye izici, okubangela izinga lokushisa lebhethri likhuphuke, okuholela ekukhuphukeni kwe-voltage.Njengoba ukukhishwa kuqhubeka, i-voltage iyancipha kancane kancane.

Njengamanje, izinhlobo eziyinhloko zamabhethri emakethe amabhethri e-ternary namabhethri e-lithium iron phosphate.Amabhethri e-ternary azinzile kangako ngenxa yokuwa kwesakhiwo emazingeni okushisa aphezulu futhi anokuphepha okuphansi kunamabhethri e-lithium iron phosphate.Kodwa-ke, ukuminyana kwawo kwamandla kuphakeme kunamabhethri e-lithium iron phosphate, ngakho-ke womabili amasistimu ayathuthuka ngokubambisana.
