Uma usanda kuthenga noma ucwaninga ngamabhethri e-lithium iron phosphate (okubhekiselwa kuwo i-lithiumnoma i-LiFeP04kule bhulogi), uyazi ukuthi zinikeza imijikelezo eminingi, ukusatshalaliswa kwamandla okulingana, futhi zinesisindo esingaphansi kwebhethri le-sealed lead acid (SLA) elifana naleli. Ubuwazi ukuthi zingashaja ngokushesha okuphindwe kane kune-SLA? Kodwa-ke uyishaja kanjani ibhethri le-lithium, noma kunjalo?

IPHROFAYILI YOKUSHAJA IBHETRI LE-LIFEPO4

Ibhethri le-LiFeP04 lisebenzisa izigaba ezifanayo zamandla kagesi angaguquki kanye namandla kagesi angaguquki njengebhethri le-SLA. Ngisho noma lezi zigaba ezimbili zifana futhi zenza umsebenzi ofanayo, inzuzo yebhethri le-LiFeP04 ukuthi izinga lokushaja lingaba phezulu kakhulu, okwenza isikhathi sokushaja sisheshe kakhulu.

Isigaba 1Ukushaja ibhethri kuvame ukwenziwa ku-30%-100% (0.3C kuya ku-1.0c) yamandla kagesi ebhethri. Isigaba 1 seshadi le-SLA ngenhla sithatha amahora amane ukuqeda. Isigaba 1 sebhethri le-lithium singathatha ihora elilodwa nje ukuqeda, okwenza ibhethri le-lithium litholakale ukuze lisetshenziswe ngokushesha okuphindwe kane kune-SLA. Njengoba kuboniswe eshadini ngenhla, ibhethri le-Lithium lishajwa ku-0.5C kuphela futhi lisashajwa cishe izikhathi ezintathu ngokushesha! Njengoba kuboniswe eshadini ngenhla, ibhethri le-Lithium lishajwa ku-0.5C kuphela futhi lisashajwa cishe izikhathi ezintathu ngokushesha!
Isigaba sesi-2Kuyadingeka kuzo zombili izikhungo zamakhemikhali ukuze ibhethri lifinyelele ku-100% $ oc. Ibhethri le-SLA lithatha amahora ayi-6 ukuqeda iSigaba sesi-2, kanti ibhethri le-lithium lingathatha imizuzu eyi-15 kuphela. Sekukonke, ibhethri le-thelithium liyashaja emahoreni amane, kanti ibhethri le-SLA livame ukuthatha imizuzu eyi-10. Ezinhlelweni zokujikeleza, isikhathi sokushaja sibaluleke kakhulu. Ibhethri le-lithium lingashajwa futhi likhishwe izikhathi eziningana ngosuku, kanti ibhethri le-lead acid lingashajwa kanye kuphela ngosuku.
Lapho zihluka khona kumaphrofayili okushajaIsigaba 3Ibhethri le-lithium alidingi i-floatcharge efana ne-lead acid. Ezinhlelweni zokugcina isikhathi eside, ibhethri le-lithium akufanele ligcinwe ku-100%S0c, ngakho-ke lingagcinwa ngomjikelezo ogcwele (lishajwe futhi likhishwe) kanye njalo ezinyangeni eziyi-6 - 12 bese isitoreji sishajwa ku-50% SoC kuphela.
Ezinhlelweni zokulinda, njengoba izinga lokuzikhipha kwe-lithium liphansi kakhulu, ibhethri le-lithium lizosebenza cishe kuze kube yilapho ligcwele noma ngabe alikashajwa izinyanga eziyi-6 kuya kweziyi-12. Isikhathi eside, kunconywa uhlelo lokushaja olunikeza ukushaja okuphezulu ngokusekelwe ku-voltage. Lokhu kubaluleke kakhulu ngamabhethri ethu e-Bluetooth lapho imodyuli ye-Bluetooth idonsa khona ugesi omncane kakhulu ebhethri ngisho noma ingasetshenziswa.

Isitoreji sesikhathi eside

Uma udinga ukugcina amabhethri akho endaweni yokugcina isikhathi eside, kunezinto ezimbalwa okufanele uzicabangele njengoba izidingo zokugcina zihlukile kumabhethri e-SLA kanye ne-lithium. Kunezizathu ezimbili eziyinhloko zokuthi ukugcina ibhethri le-SLA uma kuqhathaniswa nebhethri le-Lithium kuhlukile.
Isizathu sokuqala ukuthi ikhemikhali yebhethri inquma indawo yokugcina engcono kakhulu. Ngebhethri le-SL, ufuna ukuligcina eduze kakhulu ngangokunokwenzeka njenge-100% $OC ukuze ugweme ukugcwala kwe-sulfate, okubangela ukunqwabelana kwamakristalu e-sulfate emapuletini. Ukunqwabelana kwamakristalu e-sulfate kuzonciphisa amandla ebhethri.
Kubhethri le-lithium, isakhiwo se-terminal enhle asihlali sizinzile uma siphelelwa ama-electron isikhathi eside. Ukungazinzi kwe-terminal enhle kungaholela ekulahlekelweni kwamandla okuhlala njalo, Ngenxa yalesi sizathu, ibhethri le-lithium kufanele ligcinwe eduze kwe-50% Soc, ehlukanisa ngokulinganayo ama-electron kuma-terminal amahle nangalungile. Ukuze uthole izincomo eziningiliziwe mayelana nokugcinwa kwe-Lithium isikhathi eside, hlola lo mhlahlandlela mayelana nokugcinwa kwamabhethri e-Lithium.
Ithonya lesibili ekugcinweni yizinga lokuzikhipha. Izinga eliphezulu lokuzikhipha le-SLabattery lisho ukuthi kufanele ulifake kushaja e-float noma kushaja e-trickle ukuze uligcine liseduze ngangokunokwenzeka ne-100% Soc ukuze ugweme ukulahlekelwa amandla unomphela. Ngebhethri le-lithium, elinezinga eliphansi kakhulu lokukhipha futhi elingadingi ukuba ku-100% $OC, ungase ukwazi ukushaja ngokuncane kokulungisa.

Amashaja ebhethri anconyiwe

Kubalulekile njalo ukufanisa ishaja yakho ukuze ulethe amandla kagesi kanye ne-voltage efanele yebhethri olishajayo. Isibonelo, ngeke usebenzise ishaja engu-24V ukushaja ibhethri engu-12v. Kunconywa futhi ukuthi usebenzise ishaja ehambisana ne-chemistry yebhethri lakho, ngaphandle kwamaphuzu angenhla mayelana nendlela yokusebenzisa ishaja ye-SLA enebhethri le-lithium. Ngaphezu kwalokho, uma ushaja ibhethri le-lithium ngeshaja ye-SLA engavamile, kuzodingeka uqinisekise ukuthi ishaja ayinayo imodi yokususa i-sulfur noma imodi yebhethri elifile.
Uma unemibuzo mayelana nekhono leshaja ekhona komunye wemikhiqizo yethu, sicela usishayele ucingo noma usithumelele i-imeyili. Singajabula ukukusiza ngezidingo zakho zokushaja.
