Niaj hnub no, yuav luag txhua tus muaj lub xov tooj hauv lawv lub hnab tshos (smartphone, lub koob yees duab xov tooj, ntsiav tshuaj) uas tuaj yeem ua tau zoo dua koj lub tsev desktop, uas koj tsis tau hloov kho rau ntau xyoo, hais txog kev ua haujlwm. Txhua gadget koj muaj muaj lithium polymer roj teeb. Tam sim no cov lus nug yog: tus nyeem ntawv twg yuav nco ntsoov thaum qhov kev hloov pauv tsis tau rov qab los ntawm "tus xov tooj" mus rau cov khoom siv ntau yam?
Nws nyuaj ... Koj yuav tsum lim koj lub cim xeeb, nco ntsoov lub xyoo koj yuav koj thawj "ntse" xov tooj. Rau kuv yog nyob ib ncig ntawm 2008-2010. Thaum lub sij hawm ntawd, lub peev xwm ntawm lithium roj teeb rau ib lub xov tooj ib txwm muaj txog 700 mAh; tam sim no lub peev xwm ntawm lub xov tooj roj teeb mus txog 4 txhiab mAh.
Kev nce hauv lub peev xwm los ntawm 6 zaug, txawm tias qhov tseeb hais tias, kwv yees hais lus, qhov loj ntawm lub roj teeb tsuas yog nce 2 zaug xwb.
Zoo li peb , lithium-ion kev daws teeb meem rau UPS tau kov yeej kev lag luam sai, muaj ntau qhov zoo tsis txaus ntseeg thiab (tshwj xeeb tshaj yog nyob rau hauv ib chav neeg rau zaub mov).
Cov phooj ywg, hnub no peb yuav sim nkag siab thiab sib piv cov kev daws teeb meem raws li hlau-lithium phosphate (LFP) thiab lithium-manganese (LMO) roj teeb, kawm txog lawv qhov zoo thiab qhov tsis zoo, thiab sib piv nrog rau ib leeg raws li ntau qhov kev qhia tshwj xeeb. Cia kuv ceeb toom rau koj tias ob hom roj teeb muaj lithium-ion, lithium-polymer roj teeb, tab sis txawv ntawm cov tshuaj muaj pes tsawg leeg. Yog tias koj txaus siab rau qhov txuas ntxiv, thov, hauv qab tus miv.
Kev cia siab rau lithium thev naus laus zis hauv kev cia lub zog
Qhov xwm txheej tam sim no hauv Lavxias Federation hauv 2017 yog raws li hauv qab no.
Siv lub hauv paus: "Lub tswv yim rau kev txhim kho cov hluav taws xob cia hauv Lavxias teb sab Federation," Ministry of Energy ntawm Lavxias teb sab Federation, Lub Yim Hli 21, 2017.
Raws li koj tuaj yeem pom, lithium-ion thev naus laus zis nyob rau lub sijhawm ntawd yog tus thawj coj hauv kev ua kom muaj kev lag luam ntau lawm (feem ntau LFP thev naus laus zis).
Tom ntej no, cia peb saib cov kev hloov hauv Tebchaws Meskas, lossis ntau dua qhov tseeb, xav txog qhov tseeb ntawm cov ntaub ntawv:
Siv: ABBM yog lub zog arrays rau cov khoom siv hluav taws xob tsis cuam tshuam, uas yog siv hauv kev lag luam hluav taws xob hluav taws xob rau:
- Reservation ntawm hluav taws xob rau cov neeg siv khoom tseem ceeb tshwj xeeb yog tias muaj kev cuam tshuam ntawm lub zog hluav taws xob rau tus kheej xav tau (SN) 0,4 kV ntawm lub chaw nres tsheb (PS).
- Raws li "tsis" tsav rau lwm qhov chaw.
- Kev them nyiaj rau cov hluav taws xob tsis txaus thaum lub sij hawm siv siab tshaj plaws los txo cov hluav taws xob tsim hluav taws xob thiab cov chaw xa khoom.
- Kev sib sau ntawm lub zog thaum nruab hnub thaum nws cov nqi qis (thaum hmo ntuj).
Raws li peb tuaj yeem pom, Li-Ion thev naus laus zis, raws li xyoo 2016, tau tuav txoj haujlwm tseem ceeb thiab pom kev loj hlob sai ntawm ob lub zog (MW) thiab lub zog (MWh).
Hauv tib daim ntawv peb tuaj yeem nyeem cov hauv qab no:
"Lithium-ion thev naus laus zis sawv cev ntau dua 80% ntawm lub zog ntxiv thiab lub zog tsim los ntawm ABBM systems hauv Tebchaws Meskas thaum kawg ntawm 2016. Cov roj teeb lithium-ion muaj lub voj voog ua haujlwm tau zoo thiab tso tawm lub zog ntau dua. Tsis tas li ntawd, lawv muaj lub zog siab dua (cov hluav taws xob tsis zoo, tus sau ntawv sau tseg, uas tau coj mus rau cov roj teeb rau cov hluav taws xob Portable rau cov hluav taws xob Portable thiab cov tsheb hluav taws xob. "
Cia peb sim sib piv ob lub lithium-ion roj teeb thev naus laus zis rau UPS
Peb yuav sib piv cov hlwb prismatic ua los ntawm LMO thiab LFP chemistry. Nws yog ob lub thev naus laus zis no (nrog kev hloov pauv xws li LMO-NMC) uas tam sim no yog lub ntsiab kev lag luam tsim rau ntau lub tsheb hluav taws xob thiab tsheb hluav taws xob.
Ib qho lus piav qhia ntawm cov roj teeb hauv lub tsheb hluav taws xob tuaj yeem nyeem ntawm noKoj nug, kev thauj hluav taws xob ua li cas rau nws? Cia kuv piav qhia: kev nthuav dav ntawm lub tsheb hluav taws xob siv Li-Ion thev naus laus zis tau ntev dhau los ntawm cov qauv qauv. Thiab raws li peb paub, tag nrho cov thev naus laus zis tshiab tuaj rau peb los ntawm kim, thaj chaw tshiab ntawm lub neej. Piv txwv li, ntau lub tsheb thev naus laus zis tuaj rau peb los ntawm Formula 1, ntau cov thev naus laus zis tshiab tau los rau hauv peb lub neej los ntawm qhov chaw ua haujlwm, thiab lwm yam ... Yog li ntawd, hauv peb lub tswv yim, lithium-ion thev naus laus zis tam sim no nkag mus rau hauv kev lag luam daws teeb meem.
Cia peb saib ntawm lub rooj sib piv ntawm cov tuam txhab tseem ceeb, roj teeb chemistry thiab cov tuam txhab tsheb lawv tus kheej uas nquag tsim hluav taws xob tsheb (hybrids).
Peb yuav xaiv tsuas yog prismatic hlwb uas haum rau daim ntawv zoo rau siv hauv UPS. Raws li koj tuaj yeem pom, lithium titanate (LTO-NMC) yog tus neeg sab nraud hais txog lub zog tshwj xeeb. Tseem muaj peb lub tuam txhab ntawm prismatic hlwb tsim nyog siv rau hauv cov kev daws teeb meem, tshwj xeeb tshaj yog UPS roj teeb.
Kuv yuav hais thiab txhais los ntawm cov ntaub ntawv "Lub neej kev soj ntsuam ntawm lub neej ntev lithium electrode rau lub tsheb fais fab roj teeb- cell rau LEAF, Tesla thiab VOLVO tsheb npav" (Original "Lub neej kev soj ntsuam ntawm lub neej ntev lithium electrode rau hluav taws xob tsheb roj teeb- cell rau LEAF , Tesla thiab Volvo tsheb npav" hnub tim 11 Lub Kaum Ob Hlis 2017 los ntawm Mats Zackrisson feem ntau tshuaj xyuas cov txheej txheem tshuaj lom neeg hauv cov roj teeb tsheb, kev cuam tshuam ntawm kev vibrations thiab huab cua kev ua haujlwm, thiab kev puas tsuaj rau ib puag ncig. Txawm li cas los xij, muaj ib lo lus nthuav txog kev sib piv. ntawm ob lub lithium-ion roj teeb technologies.
Hauv kuv phau ntawv txhais lus dawb nws zoo li no:
NMC thev naus laus zis qhia txog kev cuam tshuam ib puag ncig ib puag ncig ib lub tsheb ntau dua li LFP thev naus laus zis nrog cov hlau anode roj teeb ntawm tes, tab sis nws nyuaj rau txo lossis tshem tawm qhov yuam kev. Lub tswv yim tseem ceeb yog qhov no: lub zog ntau dua ntawm NMC ua rau muaj qhov hnyav dua thiab yog li siv hluav taws xob qis dua.
1) Prismatic cell LMO technology, chaw tsim tshuaj paus , tus nqi $400.
Qhov tshwm sim ntawm LMO cell
2) Prismatic cell LFP technology, chaw tsim tshuaj paus , tus nqi $160.
Qhov tshwm sim ntawm LFP cell
3) Rau kev sib piv, cia peb ntxiv ib lub dav hlau thaub qab roj teeb ua rau LFP thev naus laus zis thiab tib yam uas tau koom nrog qhov kev xav tsis thoob , chaw tsim tshuaj paus True Blue Power.
Qhov tshwm sim ntawm TB44 roj teeb
4) Rau lub hom phiaj, cia peb ntxiv cov qauv UPS roj teeb
Zoo li classic UPS roj teeb
Cia peb muab cov ntaub ntawv los rau hauv lub rooj.
Raws li peb tuaj yeem pom, qhov tseeb, LMO hlwb muaj lub zog ua haujlwm siab tshaj plaws; cov hlau lead classic yog tsawg kawg ob zaug li lub zog txuag.
Nws yog tseeb rau txhua tus neeg tias BMS system rau Li-Ion roj teeb array yuav ntxiv qhov hnyav rau qhov kev daws teeb meem no, uas yog, nws yuav txo cov zog tshwj xeeb los ntawm kwv yees li 20 feem pua ββ(qhov txawv ntawm qhov hnyav ntawm cov roj teeb thiab cov tshuaj ua tiav. noj mus rau hauv tus account BMS systems, module plhaub, roj teeb txee tswj). Qhov loj ntawm cov jumpers, roj teeb hloov thiab lub roj teeb txee yog suav tias yog qhov sib npaug ntawm cov roj teeb lithium-ion thiab cov roj teeb ntawm cov roj ntsha lead-acid.
Tam sim no cia peb sim los sib piv cov ntsuas ntsuas. Hauv qhov no, peb yuav lees txais qhov tso tawm qhov tob rau cov hlau lead li 70%, thiab rau Li-Ion li 90%.
Nco ntsoov tias lub zog tshwj xeeb qis rau lub dav hlau roj teeb yog vim qhov tseeb tias lub roj teeb nws tus kheej (uas tuaj yeem suav tias yog ib qho module) yog nyob rau hauv cov hlau tsis muaj hluav taws kub, muaj cov khoom sib txuas thiab cov cua sov rau kev ua haujlwm hauv qhov kub thiab txias. Rau kev sib piv, kev suav yog muab rau ib lub xov tooj ntawm tes hauv TB44 roj teeb, los ntawm qhov peb tuaj yeem txiav txim siab tias cov yam ntxwv zoo ib yam li cov qauv LFP. Tsis tas li ntawd, lub dav hlau roj teeb yog tsim los rau cov nqi hluav taws xob siab / tso tawm tam sim no, uas cuam tshuam nrog kev xav tau sai sai npaj lub dav hlau rau lub davhlau tshiab rau hauv av thiab muaj qhov tso tawm loj tam sim no thaum muaj xwm txheej ceev ntawm lub nkoj, piv txwv li, poob ntawm lub hwj chim on-board
Los ntawm txoj kev, qhov no yog yuav ua li cas cov chaw tsim tshuaj paus nws tus kheej piv ntau hom ntawm aircraft roj teeb
Raws li peb pom los ntawm cov rooj:
1) Lub hwj chim ntawm lub roj teeb txee nyob rau hauv rooj plaub ntawm LMO tshuab yog siab dua.
2) Cov roj teeb lub voj voog rau LFP yog siab dua.
3) Qhov tshwj xeeb lub ntiajteb txawj nqus rau LFP yog tsawg; raws li, nrog tib lub peev xwm, lub roj teeb txee raws li hlau-lithium phosphate technology yog loj dua.
4) LFP thev naus laus zis tsis tshua muaj kev cuam tshuam rau thermal runaway, uas yog vim nws cov qauv tshuaj. Raws li qhov tshwm sim, nws suav hais tias muaj kev nyab xeeb.
Rau cov neeg uas xav kom nkag siab meej txog yuav ua li cas cov roj teeb lithium-ion tuaj yeem ua ke rau hauv cov roj teeb array ua haujlwm nrog UPS, kuv xav kom saib ntawm no.Piv txwv li, daim duab no. Hauv qhov no, qhov hnyav ntawm cov roj teeb yuav yog 340 kg, lub peev xwm yuav yog 100 ampere-teev.
Los yog ib lub voj voog rau LFP 160S2P, qhov loj ntawm cov roj teeb yuav yog 512 kg thiab lub peev xwm yuav yog 200 ampere-teev.
NYEEM NTXIV: Txawm tias muaj tseeb hais tias cov roj teeb nrog cov chemistry ntawm hlau-lithium phosphate (LiFeO4, LFP) feem ntau yog siv nyob rau hauv hluav taws xob tsheb, lawv cov yam ntxwv muaj ib tug xov tooj ntawm zoo dua LMO tshuaj formula, lawv tso cai rau them nyob rau hauv ib tug ntau dua tam sim no, thiab yog tsawg raug. rau kev pheej hmoo ntawm thermal runaway. Hom roj teeb dab tsi los xaiv tseem nyob ntawm qhov kev txiav txim siab ntawm tus neeg muag khoom ntawm kev npaj ua ke nrog kev daws teeb meem, leej twg txiav txim siab qhov no raws li ntau tus qauv, thiab qhov tsawg kawg ntawm tag nrho cov nqi ntawm cov roj teeb array yog ib feem ntawm UPS. Tam sim no, txhua hom roj teeb lithium-ion tseem qis dua tus nqi rau cov kev daws teeb meem classic, tab sis lub zog tshwj xeeb ntawm lithium roj teeb ib chav tsev loj thiab qhov me me yuav nce kev txiav txim siab rau cov khoom siv hluav taws xob tshiab. Qee zaum, qhov hnyav tag nrho ntawm UPS txiav txim siab xaiv rau cov thev naus laus zis tshiab. Cov txheej txheem no yuav tshwm sim tsis tau pom dua, thiab tam sim no cuam tshuam los ntawm tus nqi siab hauv ntu nqes qis (cov kev daws teeb meem hauv tsev) thiab kev tsis txaus ntseeg ntawm kev xav txog kev nyab xeeb hluav taws ntawm lithium ntawm cov neeg siv khoom uas tab tom nrhiav rau qhov zoo tshaj plaws UPS kev xaiv hauv kev lag luam UPS. ntu nrog lub peev xwm ntau dua 100 kVA. Cov theem nruab nrab ntawm UPS lub zog los ntawm 3 kVA mus rau 100 kVA tuaj yeem siv tau siv lithium-ion thev naus laus zis, tab sis vim yog cov khoom me me, nws kim heev thiab qis dua rau cov qauv UPS npaj siv VRLA roj teeb.
Koj tuaj yeem paub cov ntsiab lus ntxiv thiab sib tham txog cov kev daws teeb meem tshwj xeeb uas siv cov roj teeb lithium-ion rau koj chav neeg rau zaub mov lossis chaw khaws ntaub ntawv los ntawm kev xa ntawv thov los ntawm email , lossis los ntawm kev thov ntawm lub tuam txhab lub vev xaib .
