Umhlahlandlela Ophelele Webhethri Le-Lithium-Ion Forklift vs Lead-Acid

Uma kuziwa ekukhetheni ibhethri elilungile lohlelo lwakho lokusebenza, kungenzeka ukuthi unohlu lwemibandela okudingeka uyifeze. Ingakanani i-voltage edingekayo, iyini imfuneko yomthamo, i-cyclic noma i-standby, njll.

Uma imininingwane incishisiwe ungase uzibuze, "ngidinga ibhethri ye-lithium noma ibhethri le-asidi eholayo elivalwe ngokwesiko?" Noma, okubaluleke nakakhulu, "uyini umehluko phakathi kwe-lithium ne-asidi eholayo evaliwe?" Kunezici ezimbalwa okufanele uzicabangele ngaphambi kokukhetha ikhemistri yebhethri, njengoba kokubili kunamandla nobuthakathaka.

Ngenhloso yale bhulogi, i-lithium ibhekisela kumabhethri e-Lithium Iron Phosphate (LiFePO4) kuphela, futhi i-SLA ibhekisela kumabhethri e-lead eholayo/avalwe uphawu.

Ukulethwa Kwamandla Okuqhubekayo I-Lithium VS I-Lead-Acid

I-Lithium iletha inani elifanayo lamandla kuwo wonke umjikelezo wokukhipha, kuyilapho ukulethwa kwamandla kwe-SLA kuqala ngamandla, kodwa kuyahlakazeka. Inzuzo yamandla engashintshi ye-lithium iboniswa kugrafu engezansi ebonisa i-voltage ngokumelene nesimo sokushaja.

Lapha sibona inzuzo eqhubekayo yamandla ye-Lithium ngokumelene ne-Lead-Acid

Ibhethri ye-lithium njengoba kukhonjisiwe kokuwolintshi ine-voltage engashintshi njengoba iphuma kukho konke ukukhipha. Amandla umsebenzi we-voltage izikhathi zamanje. Isidingo samanje sizoba njalo futhi ngaleyo ndlela amandla alethwayo, izikhathi zamandla zamanje, zizoba njalo. Ngakho, ake sikubeke lokhu esibonelweni sempilo yangempela.

Ingabe uke wakhanyisa ithoshi waqaphela ukuthi lifiphele kunalapho ugcina ukulivula? Lokhu kungenxa yokuthi ibhethri elingaphakathi kwethoshi liyafa, kodwa alikakafi ngokuphelele. Ikhipha amandla amancane, kodwa akwanele ukukhanyisa isibani ngokugcwele.

Ukube leli bekuyibhethri ye-lithium, isibani besiyokhanya ngendlela efanayo kusukela ekuqaleni kwempilo yayo kuze kube sekupheleni. Esikhundleni sokuthi inciphe, isibani besivele singavuli nhlobo uma ibhethri ifile.

Izikhathi zokushaja ze-Lithium ne-SLA

Ukushaja amabhethri e-SLA kuhamba kancane. Kuzinhlelo zokusebenza eziningi ezijikelezayo, udinga ukuba namabhethri e-SLA engeziwe atholakalayo ukuze ukwazi ukusebenzisa uhlelo lwakho lokusebenza ngenkathi elinye ibhethri lisashaja. Kuzinhlelo zokusebenza ezibekwe eceleni, ibhethri le-SLA kufanele ligcinwe lishajwe ngokuntanta.

Ngamabhethri e-lithium, ukushaja kushesha ngokuphindwe kane kune-SLA. Ukushaja okusheshayo kusho ukuthi kunesikhathi esiningi esetshenziswa ibhethri, ngakho kudinga amabhethri amancane. Ziphinde zilulame ngokushesha ngemva komcimbi (njengakwikhophi yasenqolobaneni noma kuhlelo lokusebenza olubekwe eceleni). Njengebhonasi, asikho isidingo sokugcina i-lithium ishaja iflothi ukuze igcinwe. Ukuze uthole ulwazi olwengeziwe mayelana nendlela yokushaja ibhethri ye-lithium, sicela ubheke Ukushaja kwethu kwe-Lithium
Umhlahlandlela.

Ukusebenza Kwebhethri Lezinga Lokushisa Eliphezulu

Ukusebenza kwe-Lithium kuphakeme kakhulu kune-SLA ekusetshenzisweni kwezinga lokushisa eliphezulu. Eqinisweni, i-lithium ku-55 ° C isenayo kabili impilo yomjikelezo njengoba i-SLA yenza ekamelweni lokushisa. I-lithium izodlula umthofu ngaphansi kwezimo eziningi kodwa inamandla ikakhulukazi emazingeni okushisa aphakeme.

Ukusebenza Kwebhethri Lezinga Lokushisa Elibandayo

Amazinga okushisa abandayo angabangela ukwehla okukhulu kwamandla kuwo wonke amakhemikhali ebhethri. Ukwazi lokhu, kunezinto ezimbili okufanele uzicabangele lapho uhlola ibhethri ngokusetshenziswa kwezinga lokushisa elibandayo: ukushaja nokukhipha. Ibhethri ye-lithium ngeke yamukele ukushajwa ezingeni lokushisa eliphansi (ngaphansi kuka-32° F). Nokho, i-SLA ingamukela izindleko zamanje eziphansi ngezinga lokushisa eliphansi.

Ngokuphambene, ibhethri ye-lithium inomthamo ophezulu wokukhipha emazingeni okushisa abandayo kune-SLA. Lokhu kusho ukuthi amabhethri e-lithium akudingekile ukuba eqe enzelwe amazinga okushisa abandayo, kodwa ukushaja kungase kube into ekhawulelayo. Ku-0°F, i-lithium ikhishwa ku-70% womthamo wayo olinganiselwe, kodwa i-SLA iku-45%.

Into eyodwa okufanele icatshangelwe ekushiseni okubandayo yisimo sebhethri ye-lithium uma ufuna ukuyishaja. Uma ibhethri liqeda ukushajwa, ibhethri lizobe selikhiqize ukushisa okwanele ukuze lamukele ukushajwa. Uma ibhethri libe nethuba lokuphola, lingase lingamukeli ukushajwa uma izinga lokushisa lingaphansi kuka-32°F.

Ukufakwa kwebhethri

Uma uke wazama ukufaka ibhethri le-asidi eholayo, uyazi ukuthi kubaluleke kangakanani ukungalifaki endaweni ehlanekezelwe ukuze uvimbele noma yiziphi izinkinga ezingaba khona ngokukhipha umoya. Ngenkathi i-SLA yakhelwe ukuthi ingavuzi, ama-vents avumela ukukhululwa okusele kwamagesi.

Kumklamo webhethri le-lithium, amaseli wonke avalwa ngawodwana futhi awakwazi ukuvuza. Lokhu kusho ukuthi awukho umkhawulo ekufakweni kwebhethri ye-lithium. Ingafakwa ohlangothini lwayo, ibheke phansi, noma ime ngaphandle kwezinkinga.

Ukuqhathaniswa Kwesisindo Sebhethri

I-lithium, ngokwesilinganiso, ilula ngo-55% kune-SLA, ngakho kulula kakhulu ukuyihambisa noma ukuyifaka.

Impilo yomjikelezo uma iqhathaniswa namazinga okushisa ahlukahlukene amabhethri e-LiFePO4

I-SLA VS Isitoreji Sebhethri Lithium

I-Lithium akufanele igcinwe ku-100% State of Charge(SOC), kuyilapho i-SLA idinga ukugcinwa ku-100%. Lokhu kungenxa yokuthi izinga lokuzikhipha lebhethri le-SLA izikhathi ezi-5 noma likhulu kunebhethri le-lithium. Eqinisweni, amakhasimende amaningi azogcina ibhethri le-asidi eholayo endaweni yokugcina ngeshaja ekhohlisayo ukuze agcine ibhethri liku-100% ngokuqhubekayo, ukuze impilo yebhethri inganciphi ngenxa yesitoreji.

Uchungechunge Nokufakwa Kwebhethri Elifanayo

Inothi elisheshayo nelibalulekile: Uma ufaka amabhethri kuchungechunge nokuhambisana, kubalulekile ukuthi afaniswe kuzo zonke izici ezihlanganisa umthamo, i-voltage, ukumelana, isimo sokushajwa, kanye nekhemistri. Amabhethri e-SLA nawe-lithium awakwazi ukusetshenziswa ndawonye ochungechungeni olufanayo.

Njengoba ibhethri le-SLA libhekwa njengebhethri "eyisimungulu" uma liqhathaniswa ne-lithium (enebhodi lesifunda eliqapha futhi elivikela ibhethri), lingakwazi ukuphatha amabhethri amaningi ochungechungeni kune-lithium.

Ubude bezintambo ze-lithium bunqunyelwe izingxenye ebhodini lesifunda. Izingxenye zebhodi lesifunda zingaba nemikhawulo yamanje kanye ne-voltage ezodlula izintambo zochungechunge olude. Isibonelo, uchungechunge lwamabhethri e-lithium amane luzoba nomthamo womthamo omkhulu ongu-51.2 volts. Isici sesibili ukuvikelwa kwamabhethri. Ibhethri elilodwa eleqa imikhawulo yokuvikela lingaphazamisa ukushajwa nokushajwa kwalo lonke uchungechunge lwamabhethri. Izintambo eziningi ze-lithium zikhawulelwe ku-6 noma ngaphansi (kuncike kumodeli), kodwa ubude bezintambo eziphakeme bungafinyelelwa ngobunjiniyela obengeziwe.

Kunomehluko omningi phakathi kwebhethri ye-lithium nokusebenza kwe-SLA. I-SLA akufanele yehliswe njengoba isenomkhawulo phezu kwe-lithium kwezinye izinhlelo zokusebenza. Kodwa-ke, i-lithium iyibhethri elinamandla ezimweni zamaloli e-forklfift.
