Uas Zoo dua, Lithium Iron Phosphate Battery Pack lossis Lead-acid Battery?
Oct 04, 2023
Lithium hlau phosphate roj teeb pob VS lead-acid roj teeb, qhov twg zoo dua? Yog tias ob leeg sib tw, lawv yuav poob. Ib yam li qhov kev sib piv ntawm cov lithium hlau phosphate roj teeb pob thiab cov roj ntsha lead-acid, nws yeej ib txwm yog qhov teeb meem kub uas tib neeg tau saib xyuas. Yog li leej twg muaj zog dua? Peb yuav muaj kev ntsuam xyuas zoo hauv kab lus no.
Lithium hlau phosphate roj teeb pob thiab lead-acid roj teeb
Ntim:
Lead-acid roj teeb loj dua, feem ntau hnyav txog 15-30 kilograms.
Cov roj teeb lithium hlau phosphate yog qhov me me, feem ntau hnyav ntawm 2.5 txog 3.0 kilograms.
Zog density ratio:
Nyob rau hauv tib lub ntim, lub zog ceev ntawm lithium hlau phosphate roj teeb yog 3-4 npaug ntawm cov roj ntsha lead-acid, 2.5 npaug ntawm cov roj teeb nickel-cadmium, thiab 1.8 npaug ntawm cov roj teeb nickel-hlau hydride. Yog li ntawd, nrog tib lub peev xwm roj teeb, lithium-ion roj teeb me me thiab sib zog dua li cov roj teeb lead-acid, cov roj teeb nickel-cadmium, thiab cov roj teeb nickel-hlau hydride.
Kev pab lub neej:
Lub neej voj voog ntawm cov roj ntsha lead-acid yog kwv yees li 300 npaug ntawm cov roj teeb zoo tib yam.
Lub lithium hlau phosphate roj teeb pob tuaj yeem raug them thiab tawm ntawm 1C ntawm chav tsev kub. Lub peev xwm ntawm lub monomer tseem ntau dua 80% tom qab 2, 000 cycles, thiab 3C lub neej voj voog mus txog ntau dua 800 zaug. Lead-acid roj teeb muaj qhov xav tau siab ntawm qhov kub thiab txias, thiab lawv lub neej kev pab cuam tsawg dua 5 xyoos nyob rau hauv qhov hnyav ambient kub. Cov roj teeb lithium hlau phosphate muaj lub neej ua haujlwm ntev dua nyob rau tib lub sijhawm.
Kev ruaj ntseg nta:
Lead-acid roj teeb. Lead-acid roj teeb tuaj yeem tawg nyob rau hauv kev cuam tshuam muaj zog, ua rau muaj kev hem thawj rau cov neeg siv khoom nyab xeeb.
Lithium hlau phosphate roj teeb pob: Lithium hlau phosphate roj teeb ua tiav daws teeb meem kev nyab xeeb ntawm lithium cobalt oxide thiab lithium manganate. Lithium cobalt oxide thiab lithium manganate yuav tawg nyob rau hauv lub khob muaj zog, thiab lithium hlau phosphate Nws tau dhau qhov kev ntsuam xyuas nruj nruj thiab yuav tsis tawg txawm tias thaum muaj kev kub ntxhov.
Kev tiv thaiv ib puag ncig:
Lead-acid roj teeb rau lub tsheb hluav taws xob muaj cov hlau lead ntau, uas tuaj yeem ua paug rau ib puag ncig yog tias tsis ua haujlwm zoo.
Cov khoom siv lithium hlau phosphate tsis muaj cov hlau hnyav thiab cov hlau tsis tshua muaj, tsis muaj tshuaj lom, tsis muaj kuab paug hauv kev tsim khoom thiab siv, thiab ua raws li European RoHS cov cai. Raws li lub roj teeb ntsuab, nws tau dhau los ua qhov tseem ceeb ntawm kev mloog.
Kev tiv thaiv daim ntawv thov:
Cov roj teeb txhuas-acid feem ntau muaj qee qhov ua tsis tiav, yog li kev saib xyuas txhua hnub nquag thiab tus nqi tu yuav nce ntxiv.
Lub lithium hlau phosphate roj teeb pob tsis tas yuav tsum tau tiv thaiv ntau zaus vim nws txoj haujlwm ruaj khov thiab tsuas yog yuav tsum tau kuaj xyuas thiab ntsuas txhua hnub.
Qhov kub thiab txias:
Lead-acid roj teeb tuaj yeem siv rau hauv -20-50 ntsuas kub thiab muaj qhov tso tawm tus kheej qis.
Lub thermal ncov ntawm lithium hlau phosphate roj teeb pob yog 350 ~ 500, kev khiav hauj lwm kub kuj loj (-20~+75), thiab nws tseem tuaj yeem tso tawm 100% ntawm qhov kub siab (60 degree).
Kev them nyiaj yug:
Lead-acid roj teeb, GM lead-acid roj teeb charger, ntawm 100%, them lub sij hawm yuav nyob rau hauv 8 mus rau 10 teev.
Vim cov ntaub ntawv siab thiab cov khoom siv electrolyte ntawm lithium-ion roj teeb, lithium ferric acid roj teeb pob tuaj yeem them sai sai thiab tuaj yeem them thiab tawm sai sai ntawm qhov siab ntawm 2C. Hauv qab lub charger tshwj xeeb, lub roj teeb tuaj yeem them 1.5C hauv 40 feeb, thiab qhov pib tam sim no tuaj yeem ncav cuag 2C.
Tsis muaj cov nyhuv rov qab:
Lead-acid roj teeb muaj cov nyhuv rov qab. Rechargeable roj teeb feem ntau ua haujlwm nyob rau hauv tag nrho cov kev ua haujlwm, thiab lawv lub peev xwm yuav sai sai poob qis dua tus nqi peev xwm.
Lithium hlau phosphate roj teeb pob tsis muaj qhov tshwm sim no. Txawm hais tias lub roj teeb nyob hauv lub xeev dab tsi, koj tuaj yeem siv lub impulse. Tsis txhob muab tso tseg ua ntej them nyiaj.
Kev tsim technology:
Tus nqi ua haujlwm ntawm cov roj ntsha lead-acid feem ntau yog 10% ~ 20%.
Vim cov txheej txheem tsim khoom, tus nqi ntawm cov roj teeb lithium-ion kuj tseem loj. Ntawm cov nqi tsim khoom, tus nqi zog ntawm lithium-ion roj teeb suav txog ntau dua 40%.
Nqe:
Lub roj teeb tseem ceeb tam sim no ntawm kev ua lag luam yog 48 volts. Piv txwv tias nws yuav tsum tau hloov, cov roj ntsha lead-acid raug nqi ib ncig ntawm 380-450 yuan (48v12ah-48v20ah), thiab lub sijhawm lav yog 1 xyoo.
Lithium-ion roj teeb kuj tseem kim, txog 1, 000 yuan (48V12AH), tab sis lawv warranty yog 2 xyoos.
Tus nqi ntim tam sim no ntawm lithium hlau phosphate roj teeb yog kwv yees li peb zaug kim dua li cov roj teeb txhuas-acid. Txawm li cas los xij, raws li kev txheeb xyuas lub neej kev pab cuam, nrog tib lub peev txheej, kev pab cuam lub neej ntawm lithium-ion roj teeb tseem ntev dua.
Yog li, qhov no yog qhov kawg ntawm kev sib piv kev soj ntsuam ntawm lithium hlau phosphate roj teeb pob thiab cov roj ntsha lead-acid. Kuv ntseeg tias koj txhua tus nkag siab tias cov roj teeb lithium-ion muaj qhov ua tau zoo dua li cov roj ntsha lead-acid.
