Ma Amp Hours vs CCA: Kumvetsetsa Mafotokozedwe a Battery
*Milandu yomwe ili m'nkhaniyi yapangidwa kuchokera zaka zambiri zantchito ndi zambiri zomwe sizinatchulidwe kuti ziteteze zinsinsi za kasitomala. Magawo aumisiri omwe amatchulidwa amachokera pamikhalidwe yoyeserera yamakampani; magwiridwe antchito amasiyanasiyana malinga ndi momwe amagwirira ntchito.*
Chaka chatha kasitomala wosungiramo zinthu zozizira kumpoto kwa US adayitana kutilalatira, nati mabatire a Polinovel "sakugwira ntchito." Ndinamupempha kuti anditumizire pepala lapadera. Zinapezeka kuti agula mtundu wathu wa 48V/105Ah wopangidwira ngolo za gofu ndikuziyika pamagalimoto ofikira omwe amasinthasintha katatu. DOD yeniyeni tsiku lililonse idadutsa 92%. Palibe batire yomwe imapulumuka pamenepo.
Zinalakwika pati? Woyang'anira katundu wawo adawona nambala ya CCA yokwera kwambiri ndipo adaitanitsa. 800 CCA, ikuwoneka bwino pamapepala. Koma magalimoto ofikira alibe ma mota oyambira. CCA sichitanthauza kanthu pakugwiritsa ntchito izi. Zomwe ankafunikira zinali zapamwamba-Ah, -yakuya{5}batire yokhoza kuyenda m'njinga. M'malo mwake adagula batire yoyambira.
Timawona cholakwika ichi 3-4 nthawi zochepa mwezi uliwonse. Makasitomala ena amataya $40K-80K asanazindikire vutoli.
Ah Handles Runtime, CCA Imagwira Kuyambira. Sakanizani Ndipo Mukuwotcha Ndalama
CCA imayesa kuchuluka kwa batire lapano lomwe limatha kuphulika paminus 18 digiri Celsius. Muyezo wa SAE J537 umafunika kusunga 7.2V kwa masekondi 30. Metric iyi idapangidwa makamaka kuti azizizira-ma injini a dizilo oyambira. Zilibe kanthu kochita ndi forklift yanu yamagetsi.
Ah amayesa kuchuluka kwathunthu. Pansi pa muyezo wa C20, batire la 100Ah mongoyerekeza limapereka 5A yamakono mosalekeza kwa maola 20. M'mafakitale enieni, ziwopsezo zotulutsa zimakwera kwambiri kuposa C20, kotero mphamvu yeniyeni yogwiritsiridwa ntchito imachepa. Izi zikuphatikiza zotsatira za Peukert, zomwe ndipeza pambuyo pake.
Chifukwa chiyani ogula amasokonezeka? Chifukwa ogulitsa ambiri amayika manambala onse mbali imodzi pamapepala, kupangitsa anthu kuganiza kuti zonse ndi zofunika mofanana.
Oyang'anira malonda ena amakankhira kwambiri-Zogulitsa za CCA kuti zitheke-zogwiritsa ntchito mozungulira chifukwa chazamalonda.
Udindo wanga ndi wolunjika: ngati zida zanu zilibe injini yoyaka mkati, iwalani CCA ilipo. Yang'anani pa Ah, yang'anani pa moyo wozungulira, yang'anani kutentha kwapakati.
Apamwamba-Mabatire a CCA Afa Mozama Kwambiri-Mapulogalamu a Cycle
Sindikupanga izi. Zapamwamba-Mapangidwe a CCA amafunikira mbale zochulukira komanso zoonda kwambiri kuti ziwonjezeke pamtunda kuti zizikwera pompopompo. Koma mbale zopyapyala zimatsika mwachangu zikamawirikiza -kutulutsa. Malonda a kamangidwe awa-walembedwa bwino m'mabuku aukadaulo amakampani a batri.
Deta yogwiritsira ntchito mafakitale ikuwonetsa kuti CCA imalumikizana ndi mphamvu zenizeni zomwe zingagwiritsidwe ntchito pansi pa 0.6. Mwanjira ina, CCA yapamwamba sikutanthauza moyo wautali wautumiki. Mabatire ambiri pamapeto pake amapuma pantchito chifukwa mphamvu imazimiririka pansi pamilingo yogwiritsiridwa ntchito, osati chifukwa CCA imatsika.
Mlandu wopusa kwambiri womwe ndawonapo ndi kampani yopanga zida zolimbikira mabatire a 1000 CCA a forklifts chifukwa "ziwerengero zazikulu ziyenera kukhala zabwinoko." Zotsatira: ma batire awiri m'miyezi 18. Titasinthira ku mabatire athu a 700Ah, zida zomwezo zidatha zaka zinayi ndikupitilirabe.
Kuchuluka Kwambiri Kwanu Kweniyeni Kumachepera Pansi Pakuvotera Kutengera Momwe Mumagwiritsire Ntchito
Apa ndipamene Peukert effect imabwera. Mwachidule, mukatulutsa mwachangu, mphamvu zonse zomwe mungatenge.
Nthawi zambiri mabatire a lead{{0}acid amakhala ndi ma coefficient a Peukert pakati pa 1.2 ndi 1.6. Batire yomwe idavotera 100Ah, ngati mutulutsa pamlingo wa 2C (kuchotsa mkati mwa theka la ola), imatha kungopereka 60-70Ah yeniyeni.
Iyi si nkhani yabwino. Ndi chemistry.
LiFePO4 ili ndi ma coefficient a Peukert mozungulira 1.02-1.05, osafunikira kwenikweni. Kuvotera 100Ah kumatanthauza kuti mumapeza 100Ah, mosasamala kanthu za liwiro lotulutsa.
Kodi izi zikutanthauza chiyani pakugula zinthu? Ngati kugwiritsa ntchito kwanu kuli ndi mphamvu zochulukirapo{{0}zikuchulukirachulukira, monga ma AGV kapena magalimoto ofikira omwe amathamanga pafupipafupi, mabatire a lead-acid amafunika 25-35% yamagetsi owonjezera. Lithium mutha kukula malinga ndi zofunikira zenizeni.
Makasitomala ambiri amatengera malingaliro athu kwa ena ogulitsa omwe amatchula mitengo yotsika chifukwa sanawerengere kutayika kwa Peukert. Miyezi itatu atakhazikitsa, amapeza mabatire "sakukwanira" ndikubwerera kwa ife.
Kutentha Kwambiri pa Mphamvu Kumachepetsedwa Kwambiri
Mabatire a lead{{0}acid pa -18 digiri amataya mphamvu pafupifupi 45%. Batire yomwe imati 100Ah imangopereka pafupifupi 55Ah yomwe ingagwiritsidwe ntchito posungira kozizira.
Tikapanga masingidwe amakasitomala ozizira, timafunikira kugawa kwawo kutentha kwenikweni. Makasitomala m'modzi kudera lakumpoto anali ndi nyumba yosungiramo zinthu zazikulu 15 digiri, koma doko lodzaza nthawi zambiri limatsika pansi -10 digiri, ndi mafoloko akuyenda pakati pa madera onse awiri. Tidafikira ku -15℃yoyipa kwambiri, 40% yayikulu kuposa omwe adawagulira m'mbuyomu. Zokwera mtengo? Inde. Koma atha zaka zitatu popanda batire m'malo. Izi zisanachitike, adatenga miyezi 18 yosinthira.
LiFePO4 amakhalabe bwino mphamvu posungira pa kutentha otsika, mozungulira 70% pa -18 digiri. Ichi ndichifukwa chake mapulogalamu osungira ozizira osinthira ku lithiamu amawona makamaka ROI yachangu. Ma projekiti ena adabweza m'miyezi 17.
Lithium vs Lead-Asidi Si Funso Laukadaulo, Ndi Funso Lazachuma
Pambuyo pazaka zambiri ndikuchita bizinesi iyi, ndawona njira ziwiri zofala koma zovuta zogulitsa. Lingaliro limodzi likunena kuti "lithiyamu ndi yokwera mtengo kwambiri ndipo sizomveka." Gulu lotsutsana nalo likulimbikira kuti "acid- yonse iyenera kuchotsedwa." Palibe udindo womwe ukuwonetsa zovuta za{4}}kupanga zisankho zenizeni padziko lapansi-.
Chomwe chimatsimikizira kusankha koyenera ndi chitsanzo chanu chogwirira ntchito komanso momwe ndalama zilili. Nawa zisankho:
Lithium imamveka bwino pamene: masinthidwe awiri kapena kuposerapo, malo osungiramo ozizira, malo ogulitsa nyumba ndi okwera mtengo (lithiamu safuna zipinda za batri), ndalama zogwirira ntchito ndizokwera (lithiamu ndi kukonza ziro), magetsi ndi okwera mtengo ndi kusiyana kwa mtengo wa TOU (kutha kwacharging kwa lithiamu kumalola-kuchapira kwambiri).
Lead{{0}asidi imagwira ntchito bwino: Ogwira ntchito nthawi imodzi, kutentha kozungulira, malo sali olephereka, mwadzipereka ogwira ntchito yosamalira mabatire, ndalama ndizovuta komanso chiwongola dzanja ndichokwera.
Zomwe ndimatsutsa ndikuti "aliyense asinthe kukhala lithiamu". Ngati ndinu nyumba yaing'ono yosungiramo katundu ku Phoenix yomwe muli ndi ma forklift 5 pa shifting imodzi, lead-acid idzakuthandizani zaka 8-10. Palibe chifukwa cholipira katatu pa lithiamu.
Koma ngati ndinu DC yayikulu yomwe ikuyendetsa masinthidwe atatu, kuwerengera ndalama zonse kumakonda kwambiri lithiamu. Gome ili pansipa likuwonetsa dongosolo la TCO lomwe tidapangira kasitomala wa 50-forklift chaka chatha. Manambala enieni omwe sindingathe kugawana nawo chifukwa cha NDA, koma mawonekedwe ake ndi othandiza:
| Mtengo | Momwe Mungawerengere Lead-Asidi | Momwe Mungawerengere Lithium |
|---|---|---|
| Kugula koyamba | Mtengo wa unit × kuchuluka | Mtengo wa unit × kuchuluka (nthawi zambiri 2-2.5x) |
| M'malo mtengo | Mtengo wa unit × kuchuluka × kuzungulira m'malo (nthawi zambiri 1-2 nthawi pazaka 8) | Kawirikawiri 0 |
| Ntchito yosamalira | Kuthirira + kufananiza maola olipira × mlingo wa ola limodzi × zaka | 0 |
| Kusiyana kwamagetsi | Kutha kulipira ~ 75-80% | Kutha kulipira ~ 92-95% |
| Mtengo wa malo | Malo a chipinda cha batri × kubwereka × zaka | 0 |
Manambala enieni amayenera kuwerengedwa potengera momwe zinthu zilili. Titha kukuthandizani pakuwunikaku koma tikufuna zambiri zanu.
Ngakhale Mkati mwa Lithium, Kukula Kwakukulu vs Kung'ono Kumatengera Katswiri
Makasitomala ambiri amaganiza kuti lithiamu ndi chinthu chimodzi. Si. Dongosolo lomwelo la 48V, tili ndi zosankha za 560Ah, 700Ah, 840Ah ndi 20-35% kusiyana kwamitengo.
Pita zazikulu kwambiri ndipo umawononga ndalama. Ipita yaying'ono kwambiri ndipo DOD yatsiku ndi tsiku imakhala yozama kwambiri, yopweteka moyo. Kodi optimum ndi kuti? Zimatengera ntchito yanu.
Tili ndi mtundu wamkati womwe umatengera mtundu wa zida zanu, nthawi yosinthira, mitundu yonyamula katundu, mtunda woyenda monga zolowera ndi zotuluka zomwe zimalimbikitsidwa ndi moyo womwe ukuyembekezeredwa. Zotsatira za mtundu uwu nthawi zambiri zimasiyana ndi "matumbo akumva" ndi 30% kapena kupitilira apo.
Makasitomala m'modzi adakonza zogula 840Ah. Kusanthula kwathu kunalimbikitsa 700Ah kukhala yokwanira. Yapulumutsa $2,800 pagawo lililonse, $112K pamayunitsi 40. Zosinthazo zimachitikanso. Makasitomala wina adakonza 560Ah, kusanthula kunawonetsa kuti DOD ipitilira 85%, tidalimbikitsa kukwera mpaka 700Ah. Ndalama zochulukirapo{14}}zosakhalitsa, zosunga zambiri-nthawi yayitali.
Timasanthula izi kwaulere kwa makasitomala omwe akuwaganizira mozama. Koma timafunikira deta yeniyeni yogwiritsira ntchito, osati "pafupifupi" kapena "zochuluka kapena zochepa" mayankho. Sitingathe kuwerengera molondola pazolowetsa zosamveka bwino.
Kutembenuka Kwapadziko Lonse Ndi Msampha. Onerani Masewera a Supplier Word
CCA ili ndi miyezo inayi kapena isanu yoyesera: SAE, DIN, EN, IEC. Mayeso amasiyana, manambala sangathe kufananizidwa mwachindunji.
Msampha wodziwika kwambiri: DIN muyezo CCA ndi pafupifupi 66% ya SAE yofanana. Otsatsa ena amatchula 600 CCA osatchula muyeso uti. Mukuganiza SAE 600, koma kwenikweni ndi DIN 600, yofanana ndi SAE 400 yokha.
Malingaliro anga: funsani ogulitsa kuti akupatseni malipoti oyambira oyeserera ndikutsimikizira mulingo woyezetsa bwino. Ngati amazemba kapena satha kufotokoza bwino, mwina mungawafotokozere.
Zinthu Zomwe Mapepala Siziwonetsa Koma Muyenera Kufunsa
Standard spec sheets amapereka magawo pansi pamikhalidwe yabwino. Kugula kwenikweni kumafuna kukumba muzinthu zingapo:
Kodi moyo wa cycle unayesedwa pa chiyani?Opanga ena amati ma 5000 azungulira, koma ndi 50% DOD. Ngati muthamanga 80% DOD, ma cycle enieni angakhale 2000 okha.
Kodi pali njira yochepetsera kuchuluka kwa kutentha?Kungonena kuti "kutentha kwa ntchito -20 mpaka 60 digiri" sikuthandiza. Muyenera kudziwa kuchuluka kwa mphamvu kumakhalabe pa -20 digiri.
Kodi magawo achitetezo a BMS ndi ati?Kodi malire a chitetezo cham'tsogolo ndi chiyani? Kodi loko{0}}kumakhala ndi kutentha kotani? Izi zimakhudza mwachindunji-kugwiritsiridwa ntchito kwapadziko lonse.
Kodi chitsimikizo chimaphimba chiyani?Kodi zimatengera nthawi kapena kuchuluka kwa kuzungulira? Kodi pali zoletsa za DOD? Chimachitika ndi chiyani ngati kugwiritsidwa ntchito kupitilira zomwe zafotokozedwa?
Gulu lathu lamalonda litha kuyankha mafunso onsewa momveka bwino. Ngati wotsatsa sangathe kuyankha kapena kupotoza, muyenera kukayikira ngati luso lake ndi lokwanira kuti limuthandize pambuyo pa-ntchito zogulitsa.
Za Polinovel
Ndife m'modzi mwa opanga akale aku China omwe amayang'ana kwambiri mabatire a lithiamu. Ma Forklift, ngolo za gofu, ma AGV, zida zothandizira pansi, takhala tikugwiritsa ntchito izi kwazaka zopitilira khumi. Factory ili ku Huizhou, mizere yopanga yotsimikizika UL, CE, IEC, UN38.3.
Sindikuuzani kuti ndife "abwino kwambiri" chifukwa "zabwino" zimatengera momwe mumagwiritsira ntchito. Zomwe ndingakuuzeni ndi gulu lathu laukadaulo litha kukuthandizani kuti muyese kusanthula kodalirika m'malo mongotaya nambala yachitsanzo ndikusiyani kuganiza.
Ngati muli ndi pulojekiti yogula batire, titumizireni zitsanzo za zida zanu ndi magawo ogwiritsira ntchito. Tidzapereka malingaliro a kukula ndi kufananitsa kwa TCO. Kusanthula uku ndikwaulere, koma chonde konzani zenizeni zenizeni. Mayankho a "pafupifupi" ndi "mozungulira" salola kuwerengera molondola.
Pazokambirana zinazake za polojekiti, tumizani imelo kudzera mwa athu[tsamba lolumikizana]kapena perekani zofunsira kudzera pa fomu ya webusayiti.
