Amahora we-Amp vs CCA: Ukuqonda Ukucaciswa Kwebhethri

Amahora we-Amp vs CCA: Ukuqonda Ukucaciswa Kwebhethri

Ngonyaka odlule ikhasimende le-cold chain lawarehouse enyakatho ye-US lasibiza lizosithethisa, lithi amabhethri e-Polinovel "awasebenzi." Ngamcela ukuthi athumele ishidi le-spec. Kuvele ukuthi bathenge imodeli yethu evamile engu-48V/105Ah edizayinelwe izinqola zegalofu futhi bayifake emalolini afinyelela kude asebenzisa amashifu amathathu. I-DOD yangempela yansuku zonke yeqe ama-92%. Alikho ibhethri elisindayo kulokho.

 

Konakele kuphi? Umphathi wabo wokuthenga ubone inombolo ephezulu ye-CCA wayesefaka i-oda. 800 le-CCA, libukeka lihlaba umxhwele ephepheni. Kodwa amaloli okufinyelela awanawo ama-starter motors. I-CCA ayisho lutho kulolu hlelo lokusebenza. Wayekudinga kwakuphezulu-Ah,{5}ibhethri elikwazi ukudonsa{5}lomjikelezo ojulile. Kunalokho wathenga ibhethri yokuqala.

 

Sibona leli phutha izikhathi ezi-3-4 ubuncane njalo ngenyanga. Amanye amaklayenti alahlekelwa ngu-$40K-80K ngaphambi kokubona inkinga.

I-Ah Iphatha Isikhathi Sokusebenza, I-CCA Iphatha Ukuqala. Zixube Ushise Imali

I-CCA ikala ukuthi ibhethri lamanje lingaqhuma kangakanani ku-minus 18 degrees Celsius. Izinga le-SAE J537 lidinga ukugcinwa okungu-7.2V amasekhondi angu-30. Le metric yakhelwe ngokukhethekile izinjini ezibandayo-eziqala udizili. Ayihlangene nhlobo neforklift yakho kagesi.

U-Ah ukala umthamo ophelele. Ngaphansi kwezinga le-C20, ibhethri elingu-100Ah ngokombono lilethela i-5A yamanje ngokuqhubekayo amahora angu-20. Ezinhlelweni zangempela zezimboni, amanani okukhishwa ahamba ngaphezu kwe-C20, ngakho umthamo wangempela osebenzisekayo uyancipha. Lokho kuhilela umphumela we-Peukert, engizofika kuwo kamuva.

Kungani abathengi bedidekile? Ngoba abahlinzeki abaningi babeka zombili izinombolo eceleni komunye emakhasini athile, okwenza abantu bacabange ukuthi zombili zibalulekile ngokulinganayo.

Abanye abadayisi baze baphushe-imikhiqizo ye-CCA ephezulu ukuze benze izinhlelo zokusebenza ezijulile-zomjikelezo ngenxa yokucatshangelwa okuhlukahlukene kwezentengiso.

Isikhundla sami siqondile: uma okokusebenza kwakho kungenayo injini evuthayo yangaphakathi, khohlwa ukuthi i-CCA ikhona. Bheka u-Ah, bheka impilo yomjikelezo, bheka amajika okushisa.

-Amabhethri e-CCA Aphakeme Afa Ngokushesha Ngokujulile-Izinhlelo Zokusebenza Zomjikelezo

Angikuqambi lokhu. -Amadizayini e-CCA aphezulu adinga amapuleti amaningi futhi azacile ukuze kwandiswe indawo engaphezulu ukuze ibe namandla asheshayo. Kodwa amapuleti amancane ehla ngokushesha ngaphansi kwemijikelezo yokushaja ephindaphindiwe{3}}. Lokhu kuhweba kwedizayini{5}kuvaliwe kubhalwe kahle ezincwadini zobuchwepheshe zomkhakha webhethri.

Idatha yohlelo lokusebenza lwezimboni ibonisa ukuthi i-CCA ihlobana namandla angempela asebenzisekayo ngokuvamile angaphansi kuka-0.6. Ngamanye amazwi, i-CCA ephezulu akusho impilo yesevisi ende. Amabhethri amaningi agcina ethathe umhlalaphansi ngenxa yokuthi umthamo uba ngaphansi kwamazinga asebenzisekayo, hhayi ngoba i-CCA yehla.

Icala elingenangqondo kakhulu engiye ngalibona kwakuyinkampani yezokuthutha igcizelela amabhethri angu-1000 CCA ama-forklift ngoba "izinombolo ezinkulu kufanele zibe ngcono." Umphumela: ukushintshwa kwamabhethri amabili ezinyangeni eziyi-18. Ngemva kokushintshela kumabhethri ethu okudonsa angu-700Ah, isisetshenziswa esifanayo sisebenze iminyaka emine futhi sisaqhubeka.

 

Lingakanani Ikhono Lakho Langempela Lincipha Ngezansi Kwekhono Elilinganiselwe kuncike ekutheni Ulisebenzisa Kanjani

Yilapho umphumela we-Peukert ungena khona. Kalula nje, lapho ukhipha ngokushesha, ayancipha amandla aphelele ongawakhipha.

 

Amabhethri omthofu-avamise ukuba nama-coefficient e-Peukert phakathi kuka-1.2 no-1.6. Ibhethri elilinganiselwe ngo-100Ah, uma ulikhipha ngesilinganiso esingu-2C (uyithulula ngesigamu sehora), lingaletha kuphela u-60-70Ah wangempela.

Lena akuyona inkinga yekhwalithi. I-chemistry.

 

I-LiFePO4 inama-coefficients e-Peukert azungeze u-1.02-1.05, awanaki nhlobo. Ilinganiselwe ngo-100Ah kusho ukuthi uthola u-100Ah, kungakhathaliseki isivinini sokukhipha.

Kusho ukuthini lokhu ekuthengeni? Uma uhlelo lwakho lokusebenza lubandakanya{{0}ukulayisha ngezikhathi ezithile kwamandla aphezulu, njengama-AGV noma amaloli okufinyelela anesivinini esivamile, amabhethri omthofu{1}}adinga u-25-35% webhafa yomthamo owengeziwe. I-Lithium ungakwazi usayizi ngokwezidingo zangempela.

Amakhasimende amaningi athatha izincomo zethu zokulinganisa aziyise kwabanye abahlinzeki abacaphuna amanani aphansi ngoba abazange babale ukulahlekelwa kwe-Peukert. Ezinyangeni ezintathu ngemuva kokufakwa bathola amabhethri "awanele" bese bebuyela kithi.

Umthelela Wezinga Lokushisa Ekhundleni Ubukelwa Kancane Kakhulu

Amabhethri omthofu-e-asidi ku--18℃alahlekelwa cishe umthamo ongu-45%. Ibhethri elithi 100Ah empeleni liletha kuphela cishe u-55Ah elisebenzisekayo endaweni yokugcina ebandayo.

Uma senza usayizi wamaklayenti eketango elibandayo, sidinga ukusatshalaliswa kwawo kwangempela kwezinga lokushisa lokusebenza. Iklayenti elilodwa esifundazweni esisenyakatho linendawo yokugcina impahla engu-15℃, kodwa idokodo lokulayisha lalivame ukwehla ngaphansi kwe- -10℃, kanye nama-forklift agijima phakathi kwezindawo zombili. Sigcine silinganisela -15℃ezimbi kakhulu, 40% ezinkulu kunomhlinzeki wabo wangaphambilini ocashuniwe. Kuyabiza? Yebo. Kodwa sebesebenze iminyaka emithathu ngaphandle kokushintshwa kwebhethri. Ngaphambi kwalokho benze isilinganiso semijikelezo yokushintsha yezinyanga eziyi-18.

I-LiFePO4 igcina ukugcinwa komthamo okungcono kakhulu emazingeni okushisa aphansi, cishe ngo-70% ku- -18℃. Yingakho izinhlelo zokusebenza zokugcina ezibandayo ezishintshela ku-lithium zibona i-ROI esheshayo ikakhulukazi. Amanye amaphrojekthi athola ukukhokhelwa ezinyangeni eziyi-17.

I-Lithium vs Lead-I-Acid Akuwona Umbuzo Wezobuchwepheshe, Umbuzo Wezezimali

Ngemuva kweminyaka ngikulo mkhakha, ngibone izindlela ezimbili zokuthengisa ezijwayelekile kodwa eziyinkinga. Omunye umbono ugcizelela ukuthi "i-lithium ibiza kakhulu futhi ayinangqondo." Ikhempu ephambene igcizelela ukuthi "i-asidi{2}yomthofu kufanele isuswe yonke." Ayikho indawo ekhombisa inkimbinkimbi{4}}yokwenziwa kwezinqumo zomhlaba-zangempela.

Okunquma ukukhetha okufanele imodeli yakho yokusebenza nesimo sezezimali. Nawa amaphuzu esinqumo:

I-Lithium yenza umqondo owengeziwe lapho: amashifu amabili noma ngaphezulu, indawo yokugcina izinto ebandayo, indawo ethengiswayo iyabiza (i-lithium ayiwadingi amagumbi ebhethri), izindleko zabasebenzi ziphezulu (i-lithium ayiziro), ugesi ubiza ngokuhluka kwesilinganiso se-TOU (ukusebenza kahle kokushaja kwe-lithium kuvumela-ukushaja okuphezulu).

I-asidi yomthofu isebenza kahle uma: Ukusebenza kweshifti eyodwa, indawo yokushisa ezungezile, isikhala asivimbeli, unezisebenzi zokunakekela ibhethri ezizinikezele, imali eyinhloko iqinile futhi amanani enzalo aphezulu.

Engikuphikisayo ukuthi "wonke umuntu kufanele ashintshele ku-lithium". Uma uyindlu encane e-Phoenix usebenzisa ama-forklift angu-5 ku-shift eyodwa, i-lead-i-asidi izokusebenzela iminyaka engu-8-10. Asikho isidingo sokukhokha kathathu nge-lithium.

Kodwa uma uyi-DC enkulu esebenzisa amashifu amathathu, isamba sokubala sezindleko cishe sivuna i-lithium. Ithebula elingezansi libonisa uhlaka lwe-TCO esakhele iklayenti le-forklift engu-50 ngonyaka odlule. Izinombolo ezithile angikwazi ukwabelana ngazo ngenxa ye-NDA, kodwa ukwakheka kuyinkomba ewusizo:

Izinombolo zangempela zidinga ukubalwa ngokusekelwe esimweni sakho esithile. Singasiza ngalokhu kuhlaziya kodwa sidinga idatha yakho yokusebenza.

Ngisho Nangaphakathi Kwe-Lithium, Ukulinganisa Okukhudlwana Kuqhathaniswa Nokuncane Kuthatha Ubungcweti

Amakhasimende amaningi acabanga ukuthi i-lithium iyi-spec eyodwa. Akunjalo. Isistimu ye-48V efanayo, sinezinketho ezingu-560Ah, 700Ah, 840Ah ezinomehluko wamanani angu-20-35%.

Hamba kakhulu futhi uchithe imali. Iba mncane kakhulu futhi i-DOD yansuku zonke ijula ​​kakhulu, ilimaza ubude bempilo. Kukuphi okuhle? Kuya ngomjikelezo wakho womsebenzi.

Sinemodeli yokulinganisa yangaphakathi ethatha imodeli yakho yesisetshenziswa, ishejuli yeshifu, izinhlobo zempahla, amabanga okuhamba njengokungenayo kanye nemiphumela enconyiwe umthamo onokuphila okulindelekile. Imiphumela evela kule modeli ivamise ukuhluka "ekuzizweni kwamathumbu" ngo-30% noma ngaphezulu.

Iklayenti elilodwa ekuqaleni lalihlele ukuthenga i-840Ah. Ukuhlaziya kwethu kunconywe ukuthi i-700Ah izokwanela. Kulondolozwe u-$2,800 ngeyunithi ngayinye, u-$112K kumayunithi angama-40. Okuphambene kuyenzeka futhi. Elinye iklayenti lihlele u-560Ah, ukuhlaziya kubonise ukuthi i-DOD izodlula u-85%, sincome ukuthi inyuke ifike ku-700Ah. Imali eyengeziwe{14}}yesikhathi esifushane, ukonga okukhulu{15}}kwesikhathi eside.

Lokhu kuhlaziya sikwenza mahhala kumakhasimende acabanga ngokujulile. Kodwa sidinga idatha yokusebenza kwangempela, hhayi izimpendulo "cishe" noma "eziningi noma ngaphansi". Ayikwazi ukwenza izibalo ezinembile kokokufaka okungacacile.

Ukuguqulwa Okujwayelekile Kwamazwe Ngamazwe Kuyisicupho. Buka Amageyimu Wamagama Womhlinzeki

I-CCA inamazinga okuhlola amane noma amahlanu: i-SAE, i-DIN, i-EN, i-IEC. Izimo zokuhlola ziyahlukahluka, izinombolo azikwazi ukuqhathaniswa ngokuqondile.

Isicupho esivame kakhulu: I-DIN ejwayelekile i-CCA cishe ilingana no-66% we-SAE elinganayo. Abanye abahlinzeki bacaphuna i-600 CCA ngaphandle kokucacisa ukuthi iyiphi indinganiso. Uthatha i-SAE 600, kodwa empeleni i-DIN 600, elingana ne-SAE 400 kuphela.

Isincomo sami: cela abahlinzeki ngemibiko yokuhlola yoqobo futhi uqinisekise izinga lokuhlola ngokucacile. Uma begwema noma bengakwazi ukuchaza ngokucacile, cishe ungadlulisela kubo.

Izinto Ezicacisiwe AmaSpredishithi Azibonisi Kodwa Kufanele Ubuze Ngazo

Amashidi ajwayelekile anikeza imingcele ngaphansi kwezimo ezifanele. Ukuthengwa kwangempela kudinga ukumba ezintweni eziningana:

Iyiphi impilo yomjikelezo eyahlolwa kuyo i-DOD?Abanye abakhiqizi bathi imijikelezo engu-5000, kodwa lokho ku-50% DOD. Uma usebenzisa i-DOD engu-80%, imijikelezo yangempela ingaba ngu-2000 kuphela.

Ingabe likhona ijika lokunciphisa umthamo kulo lonke ibanga lokushisa?Ukusho nje ukuthi "izinga lokushisa lokusebenza -20 kuya ku-60 degree" akusizi. Udinga ukwazi ukuthi ungakanani umthamo osele ku--20 degree.

Yimaphi amapharamitha athile okuvikela e-BMS?Iyini i-overcurrent protection threshold? Iliphi izinga lokushisa{0}}elibandakanya ukukhiya ukushaja okuphansi? Lokhu kuthinta ngqo{1}}ukusebenziseka komhlaba kwangempela.

Iwaranti ihlanganisani ngempela?Ingabe kusekelwe esikhathini noma ekubalweni komjikelezo? Ingabe ikhona imikhawulo ye-DOD? Kwenzekani uma ukusetshenziswa kweqa imibandela ethile?

Ithimba lethu labadayisi lingaphendula yonke le mibuzo ngokucacile. Uma umphakeli engakwazi ukuphendula noma ukuphambukisa, kufanele ubuze ukuthi amandla akhe obuchwepheshe anele yini ukusekela{1}}ngemuva kwesevisi yokuthengisa.

Mayelana nePolinovel

Singabanye babakhiqizi bangaphambili baseShayina abagxile emabhethri e-lithium ashukumisayo. Ama-Forklift, amakalishi egalufu, ama-AGV, okokusebenza okusekela phansi, kade senza lezi zicelo iminyaka engaphezu kweshumi. Imboni iseHuizhou, imigqa yokukhiqiza eqinisekisiwe i-UL, CE, IEC, UN38.3.

Ngeke ngikutshele ukuthi "singcono kakhulu" ngoba "okungcono kakhulu" kuncike kuhlelo lwakho lokusebenza oluthile. Engingakutshela kona ukuthi ithimba lethu lobuchwepheshe lingakusiza wenze ukuhlaziya usayizi othembekile esikhundleni sokuvele ukhiphe inombolo yemodeli bese likushiya uqagela.

Uma unephrojekthi yokuthenga yebhethri, sithumelele amamodeli wakho wezinto zokusebenza kanye nemingcele yokusebenza. Sizohlinzeka ngezincomo zokulinganisa kanye nokuqhathaniswa kwe-TCO. Lokhu kuhlaziya kumahhala, kodwa sicela ulungiselele idatha yangempela. "Cishe" kanye "nezimpendulo" azikuvumeli ukubala okunembile.

Ukuze uthole izingxoxo eziqondile zamaphrojekthi, thumela i-imeyili ngethi yethu[ikhasi lokuxhumana]noma uthumele imibuzo ngefomu lesizindalwazi.

*Le ndatshana ibhalwe yilungu lethimba labadayisi bezobuchwepheshe be-Polinovel. Ukubuka okuveziwe kusekelwe kokuhlangenwe nakho kwangempela kwephrojekthi. Izincomo ezithize zokulinganisa zidinga iphrojekthi{2}}ukuhlolwa okuqondile.*
