Iiyure ze-Amp vs CCA: Ukuqonda iiNgcaciso zebhetri
*Amatyala akweli nqaku ahlanganiswe ukusuka kwiminyaka yamava eprojekthi kunye neenkcukacha ezingachazwanga ukukhusela ubumfihlo bomthengi. Imilinganiselo yobugcisa ekhankanyiweyo isekelwe kwiimeko zokuvavanya umgangatho woshishino; usetyenziso oluyinyani lwesicelo luyahluka ngokweemeko ezithile zokusebenza.
Kulo nyaka uphelileyo umxhasi wendawo yokugcina impahla ebandayo emantla e-US wabiza ukusikhwaza, esithi iibhetri zePolinovel "azisebenzi." Ndamcela ukuba athumele phezu kwe-spec sheet. Kwafumaniseka ukuba bathenge imodeli yethu eyi-48V/105Ah esemgangathweni eyenzelwe iinqwelo zegalufa kwaye bayifakela kwiilori ezifikelelayo ezisebenza iishifti ezintathu. Okwenziweyo mihla le iDOD igqithile kuma-92%. Akukho bhetri lisindayo kuloo nto.
Konakele phi? Umphathi wabo wokuthenga ubone inani eliphezulu leCCA waze wafaka iodolo. 800 yeCCA, ibonakala inomtsalane ephepheni. Kodwa iilori zokufikelela azinazo iimoto zokuqalisa. I-CCA ayithethi nto kwesi sicelo. Into ebeyidinga ibiphezulu-Ah, umjikelo onzulu{5}ibhetri ekwaziyo ukutsala. Endaweni yoko wathenga ibhetri yokuqala.
Sibona le mpazamo 3-4 amaxesha ubuncinci nyanga zonke. Abanye abathengi balahlekelwa yi-$ 40K-80K ngaphambi kokuba baqaphele ingxaki.
Ah Iphatha ixesha lokuSebenza, iCCA iphatha uKuqala. Zixube Utshise Imali
I-CCA ilinganisa ukuba ingakanani na ibhetri yangoku enokugqabhuka kuminus 18 degrees celcius. Umgangatho we-SAE J537 ufuna ukugcina i-7.2V imizuzwana engama-30. Lo metric uyilelwe ngokukodwa ukubanda{6}}ukuqala kweenjini zedizili. Ayinanto yakwenza neforklift yakho yombane.
Ah ulinganisa umthamo opheleleyo. Ngaphantsi komgangatho we-C20, ibhetri eyi-100Ah ithiyori ihambisa i-5A ngoku ngokuqhubekayo kwiiyure ezingama-20. Kwizicelo zokwenyani zemizi-mveliso, iireyithi zokukhupha zihamba ngaphezulu kwe-C20, ngoko ke umthamo wokwenyani osebenzisekayo uyacutheka. Oko kubandakanya impembelelo yePeukert, endiya kufika kuyo kamva.
Kutheni abathengi bebhideka? Ngenxa yokuba ababoneleli abaninzi babeka amanani omabini ecaleni kwelinye kumaphepha, okwenza abantu bacinge ukuba zombini zibalulekile ngokulinganayo.
Abanye abathengi bade batyhale phezulu{0}}iimveliso zeCCA kusetyenziso olunzulu-lomjikelo ngenxa yengqwalasela yorhwebo.
Isikhundla sam sithe ngqo: ukuba izixhobo zakho azinayo injini yokutsha yangaphakathi, libala ukuba iCCA ikhona. Jonga ku-Ah, jonga kubomi bomjikelo, jonga amagophe obushushu.
Phezulu-Iibhetri zeCCA Die Early in Deep-Cycle Application
andiyenzi lento. Ephakamileyo-Uyilo lweCCA lufuna iipleyiti ezingaphezulu nezibhityileyo ukukhulisa indawo yomphezulu yangoku ephezulu. Kodwa iipleyiti ezibhityileyo zehla ngokukhawuleza phantsi kwentlawulo ephindaphindiweyo{3}}imijikelo yokukhupha. Olu rhwebo loyilo{5} lubhalwe kakuhle kushicilelo lwebhetri loncwadi lobugcisa.
Idatha yesicelo soShishino ibonisa ukuba i-CCA ihambelana namandla okwenene asebenzisekayo ngokuqhelekileyo ngaphantsi kwe-0.6. Ngamanye amazwi, iCCA ephezulu ayithethi ubomi obude benkonzo. Uninzi lweebhetri ekugqibeleni lufumana umhlala-phantsi ngenxa yokuba umthamo uphela ngaphantsi kwamanqanaba asebenzisekayo, kungekhona ngenxa yokuba i-CCA yehla.
Eyona nto ihlekisayo ndiyibonile yinkampani yezothutho igxininisa kwiibhetri ze-CCA ze-1000 ze-forklifts kuba "amanani amakhulu kufuneka abe ngcono." Isiphumo: Ukutshintshwa kwebhetri ezimbini kwiinyanga ezili-18. Emva kokutshintshela kwiibhetri zethu zokutsalwa ze-700Ah, izixhobo ezifanayo ziqhube iminyaka emine kwaye zisahamba.
Singakanani Umthamo Owena Owakho Ocuthekayo Ngaphantsi Kwesakhono esilinganiselweyo sixhomekeke kwindlela osisebenzisa ngayo
Apha kulapho i-Peukert effect ingena khona. Ukubeka ngokulula, ngokukhawuleza ukhupha, angaphantsi kwamandla ewonke onokuwakhupha.
Ilead-iibhetri zeasidi zikholisa ukuba ne-Peukert coefficients phakathi kwe-1.2 kunye ne-1.6. Ibhetri elinganiswe nge-100Ah, ukuba uyikhupha ngereyithi ye-2C (uyikhupha ngesiqingatha seyure), inokuzisa kuphela i-60-70Ah yokwenene.
Lo ayingomba womgangatho. Yikhemistri.
I-LiFePO4 ine-coefficients ye-Peukert malunga ne-1.02-1.05, ngokuqinisekileyo ayinanto. Ukulinganisa i-100Ah kuthetha ukuba ufumana i-100Ah, nokuba sithini isantya sokukhupha.
Kuthetha ukuthini oku ekuthengeni? Ukuba isicelo sakho siquka amandla aphezulu{{0}amandla anqumayo, afana nee-AGVs okanye iilori ezifikelelayo ezinokukhawuleza rhoqo, iibhetri zeasidi ezikhokelayo zifuna i-25-35% yesithinteli somthamo owongezelelweyo. Lithium unako ubungakanani kwiimfuno zokwenyani.
Abathengi abaninzi bathatha iingcebiso zethu zokulinganisa kwabanye ababoneleli abacaphula amaxabiso aphantsi kuba bengakhange baphendule ngelahleko yakwaPeukert. Kwiinyanga ezintathu emva kofakelo bafumanisa iibhetri "azonelanga" kwaye zibuyela kuthi.
Ifuthe lobushushu kwisakhono lithathwa ngokuba ngaphantsi
I-Lead-ibhetri zeasidi kwi--18℃ilahlekelwa malunga ne-45% umthamo. Ibhetri ebanga i-100Ah eneneni ihambisa kuphela malunga ne-55Ah enokusetyenziswa kwindawo yokugcina ebandayo.
Xa sisenza ukulinganisa kubathengi bekhonkco elibandayo, sidinga ukuhanjiswa kwabo kobushushu bokusebenza. Omnye umxhasi kummandla osemantla wayenendawo yokugcina impahla kwiqondo le-15 , kodwa idokhi yokulayisha ihlala ihla ngaphantsi kwe- -10℃, kunye neeforklift ezihamba phakathi kwezowuni zombini. Sigqibe ekubeni silinganisele kwi-15℃eyona meko imbi kakhulu, i-40% inkulu kunomthengisi wabo wangaphambili ocatshulweyo. Iyabiza? Ewe. Kodwa baqhube iminyaka emithathu ngaphandle kokutshintshwa kwebhetri. Ngaphambi koko benza umyinge weenyanga ezili-18 zomjikelo wokutshintsha.
I-LiFePO4 igcina umthamo ongcono kakhulu wogcino kumaqondo obushushu aphantsi, malunga ne-70% kwi--18 degree. Kungenxa yoko le nto usetyenziso logcino olubandayo lutshintshela kwi-lithium lubona i-ROI ekhawulezayo. Ezinye iiprojekthi ziye zafumana umvuzo kwiinyanga ezili-17.
I-Lithium vs iNkokheli{0}}I-Acid ayingombuzo wobuGcisa, ngumbuzo wemali
Emva kweminyaka kolu shishino, ndiye ndabona iindlela ezimbini eziqhelekileyo kodwa eziyingxaki zokuthengisa. Enye imbono igcina ukuba "i-lithium ibiza kakhulu kwaye ayinangqiqo." Inkampu echaseneyo igxininisa ukuba "i-lead{2}iasidi kufuneka isuswe yonke." Akukho ndawo ibonisa ukuntsonkotha kokwenyani{4}kwezigqibo zehlabathi{5}}zokwenziwa.
Eyona nto imisela ukhetho olufanelekileyo yimodeli yakho yokusebenza kunye nemeko yezemali. Nanga amanqaku ezigqibo:
I-Lithium yenza ingqiqo ngakumbi xa: iishifti ezimbini okanye ngaphezulu, indawo yokugcina indawo ebandayo, indawo yokuhlala iyabiza (i-lithium ayifuni amagumbi ebhetri), iindleko zabasebenzi ziphezulu (i-lithium igcina iqanda), umbane uyabiza ngexabiso le-TOU umahluko (ubuchule bokutshaja kwe-lithium buvumela ukutshaja-incopho yokutshaja).
Lead{{0}iasidi isebenza kakuhle xa: Ukusebenza kweshifti enye, indawo engqongileyo yobushushu, indawo ayithintelwa, uzinikele kubasebenzi bokugcina ibhetri, imali eyinkunzi iqinile kwaye inzala iphezulu.
Into endiyichasayo kukuba "wonke umntu kufuneka atshintshele kwi-lithium". Ukuba uyindawo encinci yokugcina izinto ePhoenix eqhuba iiforklift ezi-5 kwishifti enye, ilothe -iasidi iya kukunceda iminyaka eyi-8-10. Akukho mfuneko yokuhlawula kathathu nge-lithium.
Kodwa ukuba uyi-DC enkulu eqhuba iishifti ezintathu, ukubalwa kwendleko iyonke phantse ngokuqinisekileyo ithanda i-lithium. Itheyibhile engezantsi ibonisa isakhelo se-TCO esakhele umxhasi we-50-forklift kunyaka ophelileyo. Amanani athile andikwazi ukwabelana ngawo ngenxa ye-NDA, kodwa ubume buluncedo kwireferensi:
| Ixabiso Into | Ubalwa njani iLead{0}}Acid | Indlela yokubala iLithium |
|---|---|---|
| Ukuthenga kokuqala | Ixabiso leyunithi × ubungakanani | Ixabiso leyunithi × ubungakanani (ngokuqhelekileyo 2-2.5x) |
| Ixabiso lokutshintsha | Ixabiso leyunithi × ubungakanani × imijikelo yokutshintshwa (ngokuqhelekileyo amaxesha angama-1-2 kwiminyaka eyi-8) | Ngesiqhelo 0 |
| Umsebenzi wokulungisa | Ukunkcenkceshela + ukulinganisa iiyure zokutshaja × izinga leyure × iminyaka | 0 |
| Umahluko wombane | Ukutshaja kakuhle ~75-80% | Ukutshaja kakuhle ~92-95% |
| Ixabiso lendawo | Indawo yegumbi lebhetri × irenti × iminyaka | 0 |
Amanani okwenene kufuneka abalwe ngokusekelwe kwimeko yakho ethile. Sinokunceda kolu hlalutyo kodwa sidinga idatha yakho yokusebenza.
Nangaphakathi kweLithium, Ubungakanani obuNkhulu vs obuncinci buthatha ubuchwephesha
Abathengi abaninzi bacinga ukuba i-lithium yinto enye. Ayiyo. Inkqubo ye-48V efanayo, sine-560Ah, i-700Ah, i-840Ah iinketho kunye ne-20-35% umahluko wexabiso.
Hamba kakhulu kwaye uchitha imali. Yiya mncinci kakhulu kwaye i-DOD yemihla ngemihla ibaleka nzulu kakhulu, yenzakalise ubomi. Uphi oyena mkhulu? Kuxhomekeke kumjikelo wakho womsebenzi.
Sinemodeli yangaphakathi yokulinganisa ethatha imodeli yesixhobo sakho, ishedyuli yeshifti, iintlobo zempahla, imigama yokuhamba njengegalelo kunye neziphumo ezicetyiswayo umthamo kunye nobomi obulindelekileyo. Iziphumo zale modeli zihlala zohluka kwi "gut feel" nge-30% okanye ngaphezulu.
Umxhasi omnye ekuqaleni wayecwangcise ukuthenga i-840Ah. Uhlalutyo lwethu lucebise ukuba i-700Ah iya kwanela. Kugcinwe i-$2,800 ngeyunithi nganye, i-$112K kwiiyunithi ezingama-40. Umva uyenzeka kwakhona. Omnye umxhasi ucwangcise i-560Ah, uhlalutyo lubonise i-DOD iya kudlula i-85%, sincoma ukunyuka ukuya kwi-700Ah. Imali eninzi{14}}yexesha elifutshane, ugcino olukhulu{15}}ixesha elide.
Senza olu hlahlelo simahla kubaxumi abacinga nzulu. Kodwa sifuna idatha yokusebenza yokwenyani, hayi "malunga" okanye "ngaphezulu okanye ngaphantsi" iimpendulo. Ayinakukwazi ukwenza izibalo ezichanekileyo kumagalelo angacacanga.
Uguqulo lweMigangatho yaMazwe ngaMazwe lungumgibe. Jonga kwiMidlalo yeLizwi loMboneleli
I-CCA inemigangatho yovavanyo emine okanye emihlanu: i-SAE, i-DIN, i-EN, i-IEC. Iimeko zovavanyo ziyahluka, amanani awanakuthelekiswa ngokuthe ngqo.
Owona mgibe uxhaphakileyo: Umgangatho we-DIN we-CCA uqikelelwa kwi-66% ye-SAE elinganayo. Abanye ababoneleli bacaphula i-600 CCA ngaphandle kokuchaza ukuba yeyiphi umgangatho. Uthatha i-SAE 600, kodwa eneneni yi-DIN 600, ilingana ne-SAE 400 kuphela.
Ingcebiso yam: cela ababoneleli ngeengxelo zovavanyo lwangaphambili kwaye uqinisekise umgangatho wovavanyo ngokucacileyo. Ukuba bayaphepha okanye abakwazi ukuchaza ngokucacileyo, mhlawumbi unokudlula kubo.
Izinto eziKhethekileyo azibonisi kodwa kuya kufuneka ubuze malunga nazo
Amaphepha asemgangathweni anika iiparamitha phantsi kweemeko ezifanelekileyo. Ukuthengwa kwempahla kufuna ukugrumba kwizinto ezininzi:
Ububom bomjikelo buvavanywe kweyiphi i-DOD?Abanye abavelisi bathi 5000 imijikelo, kodwa oko kwi 50% DOD. Ukuba usebenzisa i-80% ye-DOD, imijikelo yokwenyani inokuba ngama-2000 kuphela.
Ngaba kukho umthamo wokunciphisa igophe kuluhlu lobushushu?Ukuthi nje "ubushushu bokusebenza -20 ukuya kwi-60 degree" akuncedi nto. Kufuneka wazi ukuba ungakanani umthamo oseleyo kwi-20 degree.
Zeziphi iiparamitha ezithile zokhuseleko lwe-BMS?Yintoni i-overcurrent protection threshold? Leliphi iqondo lobushushu elibandakanyekayo-lokutshixa ukutshaja okuphantsi? Ezi zichaphazela ngqo{1}usetyenziso lwehlabathi.
Ingaba iwaranti igubungela ntoni?Ingaba isekelwe kwixesha okanye kubalwa komjikelo? Ngaba kukho izithintelo zeDOD? Kwenzeka ntoni xa ukusetyenziswa kudlula imiqathango ethile?
Iqela lethu lokuthengisa lingaphendula yonke le mibuzo ngokucacileyo. Ukuba umthengisi akakwazi kuphendula okanye ajike, kufuneka ubuze ukuba amandla abo obugcisa anele na ukuxhasa emva{1}}kwenkonzo yokuthengisa.
