ISikhokelo esiGqibeleleyo kwiBattery ye-Lithium-Ion yeForklift vs Lead-Acid

Xa kuziwa ekukhetheni ibhetri elungileyo kwisicelo sakho, unokuba noluhlu lweemeko ekufuneka uzifezekise. Ingakanani i-voltage efunekayo, yintoni imfuneko yomthamo, i-cyclic okanye i-standby, njl.

Nje ukuba iinkcukacha zicuthelwe phantsi unokuba uyazibuza, "Ngaba ndifuna ibhetri ye-lithium okanye ibhetri yeasidi etywiniweyo yesiko?" Okanye, okona kubaluleke kakhulu, "yintoni umahluko phakathi kwe-lithium kunye ne-asidi ye-lead etywiniweyo?" Kukho izinto ezininzi ekufuneka uziqwalasele ngaphambi kokukhetha ikhemistri yebhetri, njengoko zombini zinamandla kunye nobuthathaka.

Ngenjongo yale bhulogi, i-lithium ibhekisela kwiibhetri ze-Lithium Iron Phosphate (LiFePO4) kuphela, kwaye i-SLA ibhekisela kwi-acid lead / itywinwe iibhetri ze-acid lead.

Apha sijonga umahluko wokusebenza phakathi kweebhetri ze-lithium kunye ne-lead acid

Cyclic Performance Lithium VS SLA

Umehluko ophawulekayo phakathi kwe-lithium iron phosphate kunye ne-lead acid yinyani yokuba umthamo webhetri ye-lithium uzimele kwizinga lokukhutshwa. Umzobo ongezantsi uthelekisa obona mthamo njengepesenti yomthamo olinganisiweyo webhetri ngokuchasene nesantya sokukhupha njengoko sichazwe nguC (C ilingana nokukhutshwa kwangoku okwahlulahlulwe ngobungakanani bomthamo). Ngamazinga aphezulu kakhulu okukhutshwa, umzekelo .8C, umthamo webhetri ye-asidi ekhokelayo yi-60% kuphela yomthamo olinganisiweyo.

Umthamo webhetri ye-lithium vs iintlobo ezahlukeneyo zeebhetri ze-asidi ye-lead kwiindawo ezahlukeneyo zokukhupha

Iibhetri zeLithium zinobomi obude kunayo nayiphi na ipakethe yamandla e-lead-asidi. Ubomi beebhetri ze-lead-asidi yi-1000-1500 imijikelo okanye ngaphantsi. I-Lithium-ion ithatha ubuncinane i-3,000 kunye nemijikelo ngokuxhomekeke kwisicelo.

Ngoko ke, kwizicelo ze-cyclic apho izinga lokukhupha lihlala lingaphezulu kwe-0.1C, ibhetri ye-lithium ephantsi iya kuhlala inomthamo ophezulu webhetri ye-asidi ehambelanayo. Oku kuthetha ukuba kwinqanaba elifanayo lomthamo, i-lithium iya kubiza ngaphezulu, kodwa ungasebenzisa umthamo ophantsi we-lithium kwisicelo esifanayo kwixabiso eliphantsi. Iindleko zobunini xa uqwalasela umjikelezo, ukwandisa ngakumbi ixabiso lebhetri ye-lithium xa kuthelekiswa nebhetri ye-asidi ehamba phambili.

Umehluko wesibini ophawulekayo phakathi kwe-SLA kunye neLithium yinkqubo ye-cyclic ye-lithium. I-Lithium inezihlandlo ezilishumi zobomi bomjikelezo we-SLA phantsi kweemeko ezininzi. Oku kuzisa ixabiso lomjikelo we-lithium ngaphantsi kwe-SLA, oku kuthetha ukuba kuya kufuneka utshintshe ibhetri ye-lithium ngaphantsi kwe-SLA kwisicelo se-cyclic.

Unikezelo lwaMandla rhoqo I-Lithium VS i-Lead-Acid

I-Lithium ihambisa umlinganiselo ofanayo wamandla kuwo wonke umjikelo wokukhutshwa, ngelixa unikezelo lwamandla lwe-SLA luqala ngamandla, kodwa luyachithakala. I-advanteji yamandla eqhubekayo ye-lithium iboniswe kwigrafu engezantsi ebonisa i-voltage ngokubhekiselele kwimeko yentlawulo.

Apha sibona inzuzo yamandla eqhubekayo yeLithium ngokuchasene neLead-Acid

Ibhetri ye-lithium njengoko kubonisiwe kwi-orenji ine-voltage eqhubekayo njengoko ikhupha kulo lonke ukukhutshwa. Amandla ngumsebenzi wamaxesha ombane ngoku. Imfuno yangoku iya kuhlala kwaye ngaloo ndlela amandla anikezelweyo, amaxesha ombane akhoyo ngoku, aya kuhlala engatshintshi. Ke, makhe sibeke oku kumzekelo wobomi bokwenyani.

Ngaba ukhe walayita isibane waqaphela ukuba simnyama kunexesha lokugqibela wawulayita ngalo? Oku kungenxa yokuba ibhetri ngaphakathi kwesibane siyafa, kodwa ayikafi ngokupheleleyo. Inika amandla amancinci, kodwa akwanelanga ukukhanyisa ngokupheleleyo ibhalbhu.

Ukuba oku bekuyibhetri ye-lithium, ibhalbhu iya kuqaqamba nje ukusuka ekuqaleni kobomi bayo ukuya ekupheleni. Endaweni yokuba inciphe, iglowubhu ibingasoze ivuleke kwaphela ukuba ibhetri ifile.

Amaxesha okutshaja kweLithium kunye ne-SLA

Ukutshaja iibhetri ze-SLA kucotha kakhulu. Kwiinkqubo ezininzi ze-cyclic, kufuneka ube neebhetri ezongezelelweyo ze-SLA ukuze ukwazi ukusebenzisa usetyenziso lwakho ngelixa enye ibhetri itshaja. Kwii-aplikeshini zokulinda, ibhetri ye-SLA kufuneka igcinwe kwintlawulo edadayo.

Ngeebhetri ze-lithium, ukutshaja kuphindwe kane ngokukhawuleza kune-SLA. Ukutshaja ngokukhawuleza kuthetha ukuba kukho ixesha elininzi elisebenzisayo ibhetri, ngoko ke kufuneka ibhetri encinci. Bakwalulama ngokukhawuleza emva kwesiganeko (njengakwi-backup okanye kwi-app yokulinda). Njengebhonasi, akukho mfuneko yokugcina i-lithium kwintlawulo ye-float yokugcina. Ngolwazi oluthe kratya malunga nendlela yokutshaja ibhetri ye-lithium, nceda ujonge yethu Ukutshaja kweLithium
Isikhokelo.

Ubushushu obuphezulu bokusebenza kwebhetri

Ukusebenza kweLithium kuphezulu kakhulu kune-SLA kwizicelo zobushushu obuphezulu. Enyanisweni, i-lithium kwi-55 ° C isenayo kabini ubomi bomjikelezo njengoko i-SLA yenza kwiqondo lokushisa. I-lithium iyakugqwesa ilothe phantsi kweemeko ezininzi kodwa yomelele ngakumbi kumaqondo obushushu aphakamileyo.

Ubushushu obubandayo bokusebenza kwebhetri

Amaqondo obushushu abandayo anokubangela ukwehla okumandla kuzo zonke iikhemistri zebhetri. Ukwazi oku, kukho izinto ezimbini ekufuneka uziqwalasele xa uvavanya ibhetri yokusetyenziswa kobushushu obubandayo: ukutshaja nokukhupha. Ibhetri ye-lithium ayiyi kwamkela intlawulo kwiqondo lokushisa eliphantsi (ngaphantsi kwe-32 ° F). Nangona kunjalo, i-SLA inokwamkela iintlawulo zangoku eziphantsi kwiqondo lobushushu eliphantsi.

Ngokwahlukileyo, ibhetri ye-lithium inomthamo ophezulu wokukhupha kumaqondo okushisa abandayo kune-SLA. Oku kuthetha ukuba iibhetri ze-lithium akufuneki ukuba zibe ngaphezulu ziyilelwe amaqondo obushushu abandayo, kodwa ukutshaja kunokuba sisithintelo. Kwi-0 ° F, i-lithium ikhutshwe kwi-70% yomthamo wayo olinganisiweyo, kodwa i-SLA ikwi-45%.

Enye into ekufuneka uyiqwalasele kubushushu obubandayo yimeko yebhetri ye-lithium xa ufuna ukuyibiza. Ukuba ibhetri isandul' ukugqiba ukukhupha, ibhetri iya kube yenze ubushushu obaneleyo ukuze yamkele intlawulo. Ukuba ibhetri ibinethuba lokuphola, isenokungamkeli intlawulo ukuba iqondo lobushushu lingaphantsi kwe-32°F.

Ukufakwa kwebhetri

Ukuba ukhe wazama ukufaka ibhetri yeasidi ekhokelayo, uyazi ukuba kubaluleke kangakanani ukuba ungayifaki kwindawo yokuguqula ukuthintela nayiphi na imiba enokubakho ngokuphuma umoya. Ngelixa i-SLA yenzelwe ukuba ingavuzi, ii-vents zivumela ukukhutshwa okushiyekileyo kwerhasi.

Kuyilo lwebhetri ye-lithium, iiseli zonke zitywinwe ngokwahlukeneyo kwaye azikwazi ukuvuza. Oku kuthetha ukuba akukho mqobo kwindlela yokufaka ibhetri ye-lithium. Inokufakwa kwicala layo, ijonge phantsi, okanye iphakame ngaphandle kwemiba.

Ukuthelekiswa kobunzima bebhetri

I-Lithium, ngokwe-avareji, yi-55% ikhaphukhaphu kune-SLA, ngoko kulula ngakumbi ukuyihambisa okanye ukuyifakela.

SLA VS Lithium yokugcinwa kwebhetri

I-Lithium akufanele igcinwe kwi-100% ye-State of Charge (SOC), ngelixa i-SLA kufuneka igcinwe kwi-100%. Oku kungenxa yokuba izinga lokuzikhupha kwibhetri ye-SLA ngamaxesha angama-5 okanye likhulu kunelo ibhetri ye-lithium. Enyanisweni, abathengi abaninzi baya kugcina ibhetri ye-asidi ekhokelayo kwindawo yokugcina kunye neshaja ekhohlisayo ngokuqhubekayo ukugcina ibhetri kwi-100%, ukwenzela ukuba ubomi bebhetri buyancipha ngenxa yokugcinwa.

Uthotho kunye noFakelo lweBattery eParallel

Inqaku elikhawulezayo nelibalulekileyo: Xa ufaka iibhetri kuthotho kunye nokuhambelana, kubalulekile ukuba zifaniswe kuzo zonke izinto ezibandakanya umthamo, amandla ombane, ukumelana, imeko yentlawulo, kunye nekhemistri. I-SLA kunye neebhetri ze-lithium azikwazi ukusetyenziswa kunye kumtya ofanayo.

Ekubeni ibhetri ye-SLA ithathwa njengebhetri "esisidenge" xa kuthelekiswa ne-lithium (enebhodi yesiphaluka ebeka iliso kwaye ikhusele ibhetri), inokusingatha iibhetri ezininzi kwintambo kune-lithium.

Ubude bentambo ye-lithium bukhawulelwe ngamacandelo kwibhodi yesiphaluka. Amacandelo ebhodi yesekethe anokuba nemida yangoku kunye ne-voltage enokuthi idlule imitya yothotho olude. Ngokomzekelo, uluhlu lweebhetri ezine ze-lithium ziya kuba ne-voltage max ye-51.2 volts. Into yesibini kukukhusela iibhetri. Ibhetri enye eyodlula imida yokhuseleko inokuphazamisa ukutshaja kunye nokukhupha umtya wonke weebhetri. Uninzi lweentambo ze-lithium zikhawulelwe kwi-6 okanye ngaphantsi (imodeli exhomekeke), kodwa ubude beentambo eziphezulu bunokufikelelwa ngobunjineli obongezelelweyo.

Kukho umahluko omkhulu phakathi kwebhetri ye-lithium kunye nokusebenza kwe-SLA. I-SLA akufuneki ithotywe njengoko isenomphetho phezu kwe-lithium kwezinye izicelo. Nangona kunjalo, i-lithium yeyona bhetri inamandla kwiilori ze-forklfift.
