Ulayini wokushintsha yilapho inzuzo yeyunithi-yentengo yomthofu{1}} inyamalala khona. Umsebenzi-wokushintsha okuningi kusho imijikelezo engu-2–3 yokushintshanisa egcwele iloli ngalinye phakathi kwanoma yiliphi iwindi lesabelomali leminyaka emi-5; imikhumbi ye-LiFePO4, ilinganiselwe imijikelezo engu-3,000–5,000 ku-80–100%ukujula kokukhishwa, ayishintshi lutho. Izindleko zokushintsha zizodwa zisula izinzuzo zangaphambili{{1}ze-asidi, futhi yonke into ivele inqwabelane kusukela lapho.
Emsebenzini wokulungisa: 20-imikhumbi ye-asidi ehamba phambili engu-20-ekusetshenzisweni kwamashifu amaningi-okusebenzayo kudinga ukuchelela okungaguquki, ukuhlolwa kwe-electrolyte, nokushajwa kokulinganisa kwamasonto onke. Lowo mjikelezo wokulinganisa uwukukhokhisa ngokweqile okulawulwayo okudizayinelwe ukunciphisa ukugcwala kweseli esimweni-sengxenye-ye-yezimo zokushaja, futhi kumosha u-15–20% wamandla eseshini kule nqubo (mhwmag.com). Ukulandelela lezo zinqubo ngokumelene nezingodo zangempela zabasebenzi ngokuvamile kuvame amahora okusebenza angu-12–18 ahlobene nebhethri ngesonto i-LiFePO4 ewaqeda ngokuphelele. Leyo inombolo okufanele uyikhiphe ku-HR ngaphambi kokwakha isiphakamiso sangaphakathi.
Imikhumbi eshicilelwe-idatha yokuguqulwa evela kubakhiqizi bebhethri ezimbonini abadumile ibonisa isamba sokwehliswa kwezindleko zeminyaka engu-5 kufika ku-70% uma zonke izigaba zezindleko zifakiwe (roypow.com). I-arithmetic ezimele kuthebula elingenhla ihlala ebangeni elifanayo lapho imijikelezo yokumiselela ibalwa ngokugcwele.
Ulayini Wamandla: Isibalo Ongakwazi Ukusisebenzisa Ngokuphikisana Nomthethosivivinywa Wakho Wokusetshenziswa
Ibhethri elilodwa le-48V forklift ku-asidi yomthofu-, sekwephuzile emjikelezweni walo wesevisi, lisebenza ngo-70–75% -ngokusebenza kahle kohambo. I-LiFePO4 igijima ngo-95%+. Elolini elidonsa cishe u-18 kWh ngosuku ekuphetheni amandla, lelo gebe elisebenza kahle lisho ukuthi iloli eliholayo{10}lisebenzisa u-3–5 kWh ngaphezulu ngosuku lokusebenza ngokukhipha okufanayo, futhi lelo gebe liyakhula njengoba umthamo womthofu{13}}uyancipha ngemva komjikelezo ngamunye wokushintsha.
Ku-$0.12/kWh ezinsukwini zokusebenza ezingu-260: $94–$156 iloli ngalinye ngonyaka, kusukela ekuhlukeni kokusebenza kahle. Emalolini angama-20 phakathi neminyaka emi-5, lokho kungu-$9,400–$15,600 kwezinye izinto ezisetshenziswayo ngenxa yekhemistri yodwa, ngaphambi kokulungiswa kokonakala. Xhuma isilinganiso sakho sangempela sikagesi nokubala kwamaloli kulezo zinombolo. Ezisetshenziswa ezisezindaweni{13}zezindleko eziphezulu noma ukusebenza kwegridi{14}}okunamandla, le nto yomugqa ikhula ngokulinganayo.
Inkinga Yokusebenzisa Eyodwa Evela Ngemva Kokulethwa (Uma Ungabuzi Umbuzo Owodwa Kuqala)
Iposi elizimele-idatha yokuxazulula inkinga yokufakwa ikhomba ukungafani kwe-voltage kanye nezinqubo zokuxhumana ezingahambelani njengembangela cishe yokuhluleka kokushajwa kwebhethri ye-LiFePO4 yeforklift ezinkampanini eziguquliwe. Indlela yokusebenza icacile: amashaja e-lead{4}}e-asidi asebenza kuphrofayela yokushaja eyinqwaba/entantayo. Amabhethri e-LiFePO4 adinga i-CC/CV (amanje ahlala njalo ukuya{7}}umthamo ogcwele, bese kuba amandla kagesi angashintshi ukuze aqedele ukushaja), futhi amayunithi amaningi e-BMS ezimboni ngeke aqale ukushaja ngaphandle kokuxhawula ishaja ngokuxhumana okusebenzayo.CAN ibhasinoma iphrothokholi ye-Modbus RTU. Xhuma iyunithi ye-legacy-ye-asidi engakhulumi noma iyiphi iphrothokholi, futhi i-BMS ingase ikhokhise ukwamukela ngokuphawulekayo noma ivimbe iphutha phakathi kwamaviki okuqala okusebenza.
Thola lokhu kusenesikhathi, bese ubhajethela amashaja ahlakaniphile azinikele angu-6–10 kububanzi bokuguqula ngo-$900–$1,800 iyunithi ngayinye; iphrojekthi isebenza ngokuhlanzekile. Kuphuthelwe, futhi ubhekene namakholi wesevisi, isikhathi sokuphumula, kanye nengxabano yewaranti mayelana nokuthi ngubani umnikazi wenkinga. Umbuzo okufanele uwubuze noma yimuphi umphakeli ngaphambi kokusayina: ingabe i-BMS yakho idinga ukuxhumana kwebhasi le-CAN noma i-Modbus RTU ukuze kuqaliswe ukushaja, futhi yiziphi izinhlobo zeshaja eziqinisekisiwe ezihambisanayo? Umbuzo owodwa, obuzwe ngesikhathi esifanele engxoxweni yokuthengwa kwempahla, unquma ukuthi ukugunyazwa kuwukufaka-izinsuku ezimbili noma{8}}umsebenzi wokuxazulula izinkinga wamasonto amathathu.
Isitoreji esibandayoomunye umbuzo wokucaciswa ovela njalo. Amaseli e-LiFePO4 alahlekelwa ukwamukelwa kwenkokhelo ngezansi kwe-0℃ngaphandle kokufudumeza kweseli; i-specification elungile yesiqandisi nokubanda-izindawo ezihlanganisa ama-heaters ahlanganisiwe alinganiselwe ngezinga lokushisa eliphansi lokusebenza lesikhungo, ngezinye izikhathi eliphansi njengo--40 degrees . Akuwona wonke amayunithi afaka lokhu. Ukuqinisekisa izinga lokushisa{7}}elibandayo ngaphambi kokuthenga kuthatha imizuzwana engama-30.
Okuboniswa Izinyanga Ezintathu Zokuqala Zedatha Ye-Pilot
Inyanga yokuqala iyidatha yokuziphatha komsebenzisi, hhayi idatha yokusebenza kwebhethri. Ama-opharetha we-Forklift ajwayele ukuhola-amashejuli wokushintshwa kwe-asidi athatha amaviki angu-3–4 ukuze afakwe ngaphakathiithuba lokushaja, ikakhulukazi umkhuba wokuxhuma ngesikhathi sekhefu kunokulinda ukushintshwa okuhleliwe. Ukufundwa kwesikhathi somjikelezo wokushaja ngalesi sikhathi akuthembeki ngezinjongo zokuqhathanisa.
Ngeviki lesithupha kuya kwelesishiyagalombili, indlela yokushaja amathuba iba ngokwejwayelekile futhi isikhathi somjikelezo wokushaja ngokushintshana siqala ukukhiqiza izisekelo ezihlanzekile. Iloli elalihlala esiteshini sokushaja amaminithi angu-30–45 ngesikhathi sokushintsha kufanele manje lingene ngaphansi kwamaminithi angu-20, noma lisuse ukuma kwesiteji ngokuphelele lapho{4}}ukukhuphuka kwezikhathi{5}}kukhuphuka kwenzeka phansi. Emaqenjini okusebenza, lesi sikhathi sesitezi esitholiwe ngokuvamile siwumphumela odlula izilinganiso zezindleko ngoba sibonisa amandla okukhipha, hhayi njengento yomugqa kumodeli yezindleko zebhethri.
Idatha yenyanga yesithathu yokusetshenziswa kwamandla ingeyokuqala evumelekile ekuqhathanisweni okuqondile nesisekelo-se-asidi. Idatha yangaphambilini ihlanekezelwe izinguquko zokuziphatha. Kuleli qophelo, imvamisa yephutha ye-BMS iphinda izinze: ekufakweni okucaciswe kahle okunamashaja afanayo, izehlakalo zamaphutha kufanele zibe eduze kweziro. Amaphutha aqhubekayo okuxhumana kwebhasi le-CAN kuphawu lwezinyanga ezintathu-ezibonisa inkinga yokuhambisana neshaja engazange ixazululwe ngokugcwele noma ukungafani kwenguqulo ye-firmware phakathi kwe-BMS neshaja. Zombili ziyalungiseka, kodwa zombili kulula ukuzixazulula ngaphambi kwenyanga yokuqala kunangemva kwenyanga yesithathu.
Inani lokuqalisa ukulinga ezintweni zakho eziphakeme kakhulu{{0}ezisetshenziswayo: lawo maloli akhiqiza isignali ecacile yokubuyisela emuva phakathi nezinsuku ezingu-90 futhi akhiqize idatha{2}}eqondile yesikhungo ikomidi lezezimali elingakwazi ukuyiphenya. Hhayi izilinganiso zezimboni. Indawo yakho yokugcina impahla, amashifu akho, inani lakho likagesi.
Lapho i-LiFePO4 Forklift Battery Economics Ingapheli
Ukushintsha{0}}okukodwa, ukukhanya{1}}kusebenzise imisebenzi enemijikelezo yokukhipha kabusha egcwele engashintshi kanye namafasitela anele okushaja ebusuku. Kuleyo ndawo,{3}}imvamisa yokushintshwa kwe-asidi iyehla, umsebenzi wokunakekela uphansi, futhi isikhathi sokukhokha se-LiFePO4 sidlulela ezinyangeni ezingu-30–36. Icala lisekhona (ukuqedwa kokulungiswa kanye nokutholwa kwendawo yaphansi kusukela ekukhipheni ingqalasizinda eshajayo kungokoqobo), kodwa umehluko we-TCO owenza isiphakamiso se-shift esiningi siqonde sibe sincane kakhulu.
Ezinkampanini ezixubile ezihlola ukulandelana kokuguqulwa, lokhu kubalulekile ngempela. Iqoqo elincane lamaloli agijima amashifu amabili noma amathathu, noma asebenzisa{1}}izinhlelo zokusebenza ezinamandla lapho ukushajwa kwamathuba kunomthelela omkhulu, adala icala lebhizinisi lesigaba sokuqala eliqine kakhulu{2}. Ukuqala isiphakamiso ngalawo mayunithi, ngomephu womgwaqo ohlukaniswe ngezigaba wayo yonke eminye yemikhumbi, kuwuhlaka olugunyazwa kakhulu kunesicelo esigcwele-sokuguqulwa kwemikhumbi esisekelwa izilinganiso zokusetshenziswa ezihlanganisiwe.
Ukwakha Imodeli Ngezinombolo Zakho
I-Fleet-imodeli ethile ye-TCO iyingxenye yalokho esikwenzayo ngaphambi kwanoma yisiphi isincomo sokuthenga. Okokufaka okukhiqiza imodeli yangaphakathi evikelekayo yilawo asevele ekhona kumarekhodi esikhungo sakho: amahora okusebenza okugcinwa kwebhethri kusukela ezinyangeni eziyi-12 ezedlule, umlando wokuthenga wokushintsha, kanye nenkokhelo yensiza yamanje ngendawo yokusebenza uma unayo. Kusukela kulokho okokufaka, ukuqhathanisa kweminyaka engu-5-kusukela kusakhiwo sangempela sezindleko zenkampani yakho esikhundleni sokuqagela okumaphakathi komkhakha okuzophonselwa inselelo ezezimali.
Emaqenjini asesigabeni sokwakha icala lokugunyaza langaphakathi, noma ukuhlola ukuthi iyiphi ingxenye yemikhumbi ezophakamisa kuqala, ingxoxo ngokuvamile iqala ngokulungiselelwa kwemikhumbi kanye{0}}nobunikazi bemoto obusetshenziswa phezulu. Ukusuka lapho, ububanzi bokuhlola kanye nomugqa wesikhathi kuqondile ukuwuchaza.
