Cov roj teeb lithium tam sim no tau siv nyob rau hauv ntau yam kev lag luam, ua-roj teeb tau hloov, thiab lwm yam hluav taws xob, tsev, nce mus rau hauv tsev.
Yog li yuav ua li cas xaiv txoj cai lithium roj teeb kom tau raws li koj cov kev xav tau?
Ua ntej, nkag siab txog koj daim ntawv thov / LOAD YUAV TSUM
1. HWJCHIM HWJ HUAM
Feem ntau yuav tsum tau: Txiav txim siab lub voltage ntau yuav tsum tau los ntawm koj load. Qhov tam sim no nominal voltage ntawm lithium-ion hlwb yog ntawm 3.2V thiab 3.7V. Tus nqi tshwj xeeb nyob ntawm seb cov khoom siv hluav taws xob zoo thiab tsis zoo rau hluav taws xob ntawm lub roj teeb. Piv txwv li, cov nominal coralt cobalal olide thiab ternary lithium lub hlwb yog hais txog ntawm iron phosphate hlwb yog 3.2V.
Cov kev xav tau overcurrent: ua kev txiav txim siab ua raws li qhov tseem ceeb tshaj plaws tau noj los ntawm qhov yuav tsum tau txuas. Tam sim no, cov roj teeb lithium muaj nruab nrog cov khoom lag luam ntse bms los saib xyuas lub roj teeb los tiv thaiv kev tawm ntawm lub roj teeb.
2. Lub zog yuav tsum tau ua
Lub peev xwm (AH): laij tag nrho tag nrho lub zog hluav taws xob uas xav tau raws li cov ntawv thov lub sijhawm thiab kev siv fais fab.
Zog ntom ntom: xav txog lub zog ntom ntom, uas cuam tshuam qhov loj thiab qhov hnyav ntawm lub roj teeb. Lub zog hluav taws xob ntau dua yog qhov tseem ceeb rau cov ntawv thov nqa khoom.
Nyeem kab lus no los kawm txog cov kev xav tau lub zog
3. Kev Txwv Lub Cev
Qhov loj me thiab cov duab: txiav txim siab lub roj teeb loj yuav tsum muaj rau cov xwm txheej xav tau ua ntej kom tsis txhob muaj qhov loj me lossis tsis tau raws li cov xwm txheej siv. Yog tias cov roj teeb uas xav tau tsis yog ib qho kev tsim hluav taws xob hauv ntiaj teb xws li} nti hluav taws xob thiab siv hluav taws xob ib txwm muaj zog uas tuaj yeem muab kev hloov kho tus kheej.
Qhov hnyav: rau kev taug kev sab nraud, Nuv ntses, RVS thiab lwm yam kev thov kev xaiv, nws yog qhov zoo tshaj plaws los siv cov roj teeb sib zog kom tsis txhob muaj qhov hnyav tsis tsim nyog.
Thib ob, ntau hom kev sib txawv ntawm cov roj teeb lithium-ion
1. Lithium cobalt oxide (Licoo2)
Pros: High Zog Zog Hluav Taws Xob, Haum rau Cov Khoom Siv Hluav Taws Xob.
Cons: tsawg tsawg lub neej, nkag siab txog qhov kub siab.
2. Lithium Iron phosphate (Liamo4 / LFP)
Pros: Lub neej ntev ntev, thermal ruaj khov, kev nyab xeeb kev nyab xeeb, qis tus kheej-kev tawm tsam tus kheej thiab tsis muaj kev nco cov nyhuv.
Cons: qis zog zog ceev piv rau lwm hom. Dav siv nyob rau hauv cov tsheb kauj vab hluav taws xob thiab hnub ci phot photovoltaics lub zog ntim tshuab
3. Lithium manganese oxide (limn2o4)
Pros: Zoo thermal stability, muaj zog tawm khoom.
Cons: qis zog zog ceev ceev, luv dua lithoman.
4. Lithium npib tsib xee manganese cobalt oxide (linimncoo2 / nmc)
Pros: Ntshiab Zog Zog, Lub Hwj Chim, thiab Kev Ua Neej.
Cons: kim kim, cov txheej txheem ua haujlwm nyuaj.
5. Lithium Titanate (LI4TI5O12 / LTO)
Pros: Ntev ntev lub neej, muaj kev nyab xeeb siab, tus nqi siab thiab tawm haujlwm kom tsis ntev.
CONS: Lithium Titanate muaj lub zog tsis tshua muaj zog, uas txhais tau tias nws tsis khaws hluav taws xob roj teeb lithium ntawm tib lub cev hnyav thiab ntim. Nws yog feem ntau siv nyob rau hauv chaw tsheb hluav taws xob hauv hluav taws xob, cov phiaj xwm hluav taws xob cia, cov khoom siv muaj khoom tshwj xeeb thiab lwm thaj chaw.
Thib peb, cov naj npawb tseem ceeb ntawm lithium roj teeb
1. Lub Neej Lub Neej
Kev Txhais Lus: Lub sijhawm ua voj voog roj teeb hais txog tus lej ntawm cov roj teeb thiab txo qis dua 80% lossis tsawg dua ntawm lub peev xwm ntsuas.
Qhov tseem ceeb: Lub neej ntev lub neej ntev pab txo cov roj teeb tu thiab lwm tus nqi.
2. Them Nqi
Kev txhais: Qhov ntau ntawm hluav taws xob lub zog uas lub roj teeb tuaj yeem lees txais ib lub sijhawm thaum lub tsheb roj teeb, kuj muaj peev xwm hnov cov roj teeb roj teeb, feem ntau tuaj yeem hnov 1c them nyiaj lossis 2c. Nws cuam tshuam los ntawm cov hom roj teeb, muaj peev xwm, cov khoom siv chemistry thiab them nyiaj. Qhov siab dua tus nqi them nyiaj, luv luv lub sijhawm nws yuav siv sijhawm them rau cov roj teeb sai sai tej zaum yuav ua rau muaj roj teeb luv luv lub neej lossis kev nyab xeeb.
Qhov tseem ceeb: ceev them ceev ceev yog qhov tseem ceeb rau cov ntawv thov uas yuav tsum tau them se nrawm, xws li hluav taws xob, xov tooj txawb, thiab lub laptop.
3. Kev Tawm Tsam
Kev txhais: tus nqi thaum lub roj teeb tuaj yeem xa lub zog.
Qhov tseem ceeb: Cov nqi siab yuav tseem ceeb rau cov kev siv hluav taws xob zoo li cov cuab yeej hluav taws xob thiab cov tsheb hluav taws xob.
Tus nqi them thiab txo nqi tawm {{0}}}}}}}}} Txoj Kev Nyuaj Siab / Kev Tso Tawm; Piv txwv li, thaum lub roj teeb nrog lub peev xwm sib sau ntawm 100a tau tawm ntawm 20a, nws cov kev tshem tawm yog 0.2c. Yog tias lub peev xwm tawm hauv 1 teev, nws hu ua 1C tawm; Yog tias nws raug rho tawm hauv 5 teev, nws hu ua 1 / 5=0. 2c tawm.
Plaub, Qhov Kev Tiv Thaiv Kub Kub
Qhov ntsuas kub ntau tshaj uas lub roj teeb tuaj yeem ua haujlwm tau zoo.
Roj teeb nrog kub npau taws yog qhov tseem ceeb rau cov ntawv thov hauv ib puag ncig. Tam sim no, lub roj teeb nrog qhov kub tshaj plaws kub ua tsis tau zoo yog lithium iron phosphote roj teeb, uas yog 2 txog 3 zaug ntawm lwm hom lithium roj teeb.
Thib tsib, kev ceev faj kev nyab xeeb.
Tam sim no, cov roj teeb lithium tau nruab nrog built-in bms thiab lub xov tooj ntawm tes rau remotely saib lub roj teeb thiab ua kev tswj hwm lub sijhawm tiag tiag. Nyob rau hauv cov nqe lus ntawm kev tshaj lij, dhau-tawm, luv Circuit Court, thiab lwm yam.
Thib rau, them nyiaj.
Ntawm tam sim no, kev sib tw hauv cov roj teeb lithium roj teeb muaj kev cuam tshuam. Thaum ua tus nqi siv nyiaj, daim ntawv thov cov xwm txheej ntawm cov roj teeb yuav tsum tau txiav txim siab ua ntej. Cov roj teeb fais fab thiab cov hluav taws xob cia khoom muaj ntau qhov kev ua yeeb yam xws li lub zog ntom thiab tus nqi them nqi, thiab lawv cov nqi kuj sib txawv. Thaum ua tus nqi siv nyiaj, cov neeg yuav khoom kom ntseeg tau yuav tsum tau txiav txim siab, thiab ib qho tsis tuaj yeem pom cov nqi qis.
Nws yog ib qho tsim nyog los ua kom paub tseeb tias cov chaw tsim tshuaj paus siv A-qib tsis muaj kev phom sij, yog li kom zam dhau cov teeb meem tom qab kev siv luv luv.
Lvwo ZogMuaj Park npog electrode cov ntaub ntawv, pob tw, ntim khoom siv hluav taws xob nrog rau cov chaw tsim khoom siv hluav taws xob thiab cov khoom siv science.
Muab kev pabcuam ib zaug, los ntawm cov khoom siv raw rau lub zog cia lub zog, cov kev pab them tag nrho.
