mAh ua haujlwm zoo rau cov khoom siv hluav taws xob. Nyob rau hauv industrial motive zog yuav khoom, nws yog qhov uas feem ntau specification teeb meem pib. Cov qauv yog lej hauv tsev kawm theem nrab: Wh=mAh × V ÷ 1000. Qhov teeb meem yog qhov V tiag tiag txhais tau tias thaum cov neeg muag khoom sib txawv siv cov lej sib txawv, thiab cov lej tuaj yeem sib txawv ntau dua 20%.
Muaj ib tus neeg siv khoom cia txias xyoo tas los coj peb nqe lus los txheeb xyuas. Tib yam nominal spec: 48V 460Ah forklift roj teeb. Cov nqi sib txawv ntawm $ 4,200 txog $ 6,800. Nws xav paub tias tus nqi kim puas tau rub nws tawm.
Kuv hais rau nws kom thov 0.5C tawm nkhaus ntawm tag nrho peb thiab xyuas qhov kev nyeem ntawv voltage ntawm 50% SOC. Ib qho pom 51.2V, ib qho pom 48V, qhov thib peb tsis tuaj yeem tsim cov ntaub ntawv txhua. Thawj ob, ob qho tib si thov 460Ah, sib txawv los ntawm ze li ntawm 1,500Wh thaum koj xam nws tiag tiag. Qhov $ 4,200 nqe lus muaj tus nqi siab tshaj plaws rau ib lub zog tiag tiag.
Dab tsi4 60ahTiag txhais tau tias ntawm ib qho Quote
LiFePO4 cell ua hauj lwm voltage khiav roughly 2.5V rau 3.65V. Lub 48V system xav tau 15 hlwb hauv series, yog li qhov tseeb pob qhov hluav taws xob hloov pauv ntawm 37.5V txog 54.75V. Tib lub roj teeb, tib qhov kev ntsuas Ah, txawv kiag li Wh nyob ntawm seb koj ntsuas qhov twg.
| SOC State | Qhov System Voltage | Konvertiere 460A in AWM |
|---|---|---|
| Tus nqi tag nrho | 54.75V | 25,185 |
| Nruab nrab -point | 51.2V | 23,552 |
| Nominal | 48V | 22,080 |
| Nyob ze kev txiav tawm | 40V | 18,400 |
Qee tus neeg muag khoom hais ntawm nominal voltage, qee qhov ntawm nruab nrab -taw tes, qee qhov tsuas yog sau tus lej Ah thiab cia koj twv. Polinovel specs siv nruab nrab -point voltage tsis tu ncua. FL51460 ntsuas ib ncig ntawm 23,500Wh. Muab piv rau tus neeg sib tw siv 48V nominal lej qhia 22,080Wh, peb saib kim dua. Lub zog tiag tiag xa tuaj yuav zoo ib yam lossis peb yuav pheej yig dua.
Yuav ua li cas xyuas:Tau txais cov ntaub ntawv pov tseg nkhaus raw ntawm koj cov neeg muag khoom. Nyeem voltage ntawm 50% SOC. Hloov tag nrho cov quotes rau tib lub hauv paus voltage ua ntej muab piv rau chav tsev nqi. Ib tus neeg muag khoom uas tsis tuaj yeem tsim cov nkhaus yog tsis tau sim lossis tsis nyiam cov txiaj ntsig. Txawm li cas los xij, tsim nyog xav txog qhov txhais tau li cas rau kev sib koom tes.
Tus nqi yuav khoom tsuas yog lub tswv yim
Lead-acid procurement cwj pwm tuag nyuaj. Saib ntawm tus nqi pib thiab lub voj voog suav, ua ib daim ntawv nthuav qhia, xaiv tus lej qis tshaj. Nrog lithium, qhov kev suav ntawd nco ntau dhau.
Peb tau taug qab kev siv nyiaj tiag tiag ua ntej thiab tom qab hloov pauv ntawm ntau qhov chaw neeg siv khoom. Ib ob - hloov chaw cia khoom khiav 20 mus txog cov tsheb thauj khoom ntawm cov hlau lead-acid. Cov nqi zais lawv yeej tsis paub tias lawv tau nqa:
Kev tu dej.
15-20 feeb ib lub roj teeb ib lub lim tiam . 40 roj teeb tag nrho. Lub hli ua haujlwm raug nqi tshaj $800 tsuas yog rau qhov ntawd. faus nyob rau hauv lub warehouse general overhead, yeej tsis itemized cais.
Hloov sijhawm.
Lead-acid tsis tuaj yeem hloov pauv tag nrho, yog li nruab nrab - hloov roj teeb hloov. Txhua qhov sib pauv khiav 30+ feeb. Ob txoj kev hloov hauv ib hnub txhais tau tias ob qhov kev sib pauv. Ib lub tsheb thauj khoom, ib teev ib hnub tsuas yog hloov roj teeb. Nees nkaum lub tsheb, nees nkaum txiv neej- teev. Ntxiv rau 22 hnub ua haujlwm thiab koj tus nqi zog.
Xyoo 3 pob tsuas.
Lead-acid cycled ntawm 50% DoD pib poob ntawm pob tsuas nyob ib ncig ntawm peb xyoos. Kev yuav khoom piv "lub neej voj voog" tus lej ntawm kev yuav khoom. Tus neeg muab khoom hais tias 2,000 cycles. Tiag - ntiaj teb tau txais tej zaum 1,400 ua ntej hloov.
Tsis muaj qhov no tshwm sim nyob rau hauv nqe lus.
Polinovel FL51420 ncav cuag lub tsheb roj teeb txhawb nqa lub sijhawm them. Nees nkaum feeb tom qab noj su ntxiv cov kua txiv txaus kom tiav ib hnub. Swap txheej txheem tshem tawm. Kev ywg dej tsis muaj nyob. Tus nqi tau txais thawj zaug yog siab dua lead-acid ho. Seb nws them rov qab yog nyob ntawm koj qhov kev ua haujlwm tshwj xeeb.
Thaum Ua Li Cas Thiaj Them Rov Qab
Tus lej 14-18 lub hlis kev lag luam txhais tau tias tsis muaj dab tsi vim tias txhua qhov haujlwm sib txawv.
Xam koj li:
(Lub hli ua dej num × teev tus nqi) + (Swap txheej xwm × lub sij hawm ib swap × teev tus nqi) + (Lub hli kWh tau siv × efficiency gap × hluav taws xob tus nqi)=Tus nqi zais txhua hli
LFP tau txais txiaj ntsig ÷ Tus nqi zais txhua hli=Lub hli them rov qab
Pob zeb scenario: 20 lub tsheb thauj khoom, ob txoj haujlwm ua haujlwm, $ 28 / teev ua haujlwm, $ 0.11 / kWh hluav taws xob. Raws li tus neeg siv cov ntaub ntawv peb tau taug qab, tus nqi zais txhua hli yog $ 4,200 txog $ 5,800 nyob ntawm qhov sib pauv zaus thiab cov qauv them.
Ib - roj teeb nqi ntawm $ 3,500 dhau ib nrab ntawm -tier lead-acid, zaus 20 units, sib npaug $ 70,000 incremental peev. Muab faib los ntawm $5,000 nyiaj txuag txhua hli, them rov qab rau lub hli 14. Tus nqi zog ntau dua, tus nqi hluav taws xob ntau dua, kev sib pauv ntau zaus, koj yuav pom lub hli 12. Cov lej qis dua thawb nws tawm ntxiv.
Tsuas yog koj paub koj tus lej tiag. Tsuas yog koj tuaj yeem khiav qhov kev suav no rau koj txoj haujlwm.
Lub peev xwm loj dua tsis yog kev pov hwm, Nws yog qhov ntxiab
Lead-acid logic hais tias yuav lub roj teeb loj tshaj plaws uas haum. Tawm hauv chav rau cov npoo. Qhov kev xav ntawd rov qab nrog LFP.
Lithium hlau phosphate muaj hnub nyoog sai dua thaum zaum ntawm tus nqi siab. Koj spec 40% oversized, ua haujlwm txhua hnub tsuas yog siv 60% ntawm lub peev xwm, roj teeb ntab hauv siab -voltage territory tsis tu ncua. Ib xyoo zoo saib. Xyoo ob, degradation accelerates. Xyoo peb, nws poob sib nrug. Tuag ntxov dua li lub roj teeb uas raug cai yuav muaj.
Qhov loj me me ua haujlwm rov qab los ntawm kev siv hluav taws xob tiag tiag, siv kev kho qhov kub thiab txias, C- kev kho tus nqi, cov npoo laus, tuaj txog ntawm lub peev xwm. Kev kho qhov txias txias sib txawv kiag li ntawm ambient warehouse. Siab -cycle AGV daim ntawv thov siv lwm txheej ntawm kev suav tag nrho.
Cov ntsiab lus ntawm no koom nrog Polinovel cov ntaub ntawv kuaj sab hauv thiab kev paub txog kev nkhaus uas tsis haum rau hauv tsab xov xwm pej xeem. Yog tias koj tau txais ib qhov project tshwj xeeb nyob rau hauv kev ntsuam xyuas, xa dhau qhov kev ua haujlwm tsis tau thiab peb yuav tsim cov lus pom zoo rau qhov loj me.
Dab tsi koj tus neeg muab khoom cov ntaub ntawv yuav tsum suav nrog
Tshem tawm curves.Yam tsawg kawg peb: 0.2C, 0.5C, 1C. Qhia tau hais tias qhov voltage coj li cas nyob rau hauv cov nqi sib txawv.
Cov ntaub ntawv ua haujlwm kub.Lub peev xwm tuav tau los ntawm -20℃mus rau +60℃. Kev khiav txias cia yam tsis tau kuaj xyuas daim ntawv no kom zoo txhais tau tias lub caij ntuj no tsis zoo tom ntej.
Cycle life test reports.Yuav tsum xeev cov kev xeem: kub, DoD feem pua, tus nqi / tso tawm. Qee tus neeg xa khoom thov 4,000 lub voj voog tab sis kev sim ntsuas yog 25 degree, 50% DoD, 0.3C. Tsis muaj dab tsi zoo li koj qhov chaw ua haujlwm tiag tiag.
UN38.3 daim ntawv pov thawj thauj.Lub hauv paus xav tau.
Polinovel muabtag nrho cov saum toj no raws li tus qauv. Yog tias cov neeg muag khoom koj tab tom sib piv tam sim no tsis tuaj yeem tsim cov ntaub ntawv sib npaug, xav txog qhov sib txawv ntawd txhais li cas.
Kauj ruam tom ntej
Polinovel tau tsim cov roj teeb hluav taws xob muaj zog txij li xyoo 2012. Forklifts, AGVs, tsheb golf, cov khoom siv txhawb nqa hauv tshav dav hlau. Peb paub qhov twg lithium qhov zoo yog qhov tseeb thiab qhov twg qhov hloov pauv yuav tsis tsim nyog.
Yog tias koj muaj ib qhov project tshwj xeeb hauv kev ntsuam xyuas, xa koj lub sijhawm ua haujlwm, hloov pauv zaus tam sim no, cov ntaub ntawv teev teev tu yog tias koj tau txais lawv. Peb mam li tsim ib qho kev ntsuam xyuas sizing nrog cov kev xav thiab kev suav sau kom meej. Koj tuaj yeem txheeb xyuas cov lej ntawm koj tus kheej.
Kev tshuaj xyuas feem ntau yuav siv li ib lub lis piam. Txawm hais tias koj tsis tuaj yeem xaiv peb cov khoom, koj yuav muaj lub hauv paus kev txiav txim siab koj tuaj yeem tiv thaiv nyiaj txiag thiab kev ua haujlwm.
