Lithium-ion roj teeb: ib daim ntawv qhia kev yuav khoom

Andrew piav qhia tias vim li cas qhov zoo yuav tsum raug xaiv thaum txhim kho lithium-ion roj teeb, thiab cov roj teeb lithium hlau phosphate zoo tshaj plaws hauv khw peb xaiv
Cov roj teeb lithium muaj ntau dua li cov hmoov lead-acid thiab theoretically muaj yuav luag ob npaug ntawm lub peev xwm ntawm txhuas-acid.
Tus yuam sij rau kev txhim kho cov roj teeb lithium-ion zoo tiag tiag, rau cov neeg uas xav siv cov cuab yeej siv roj teeb tshiab lossis txawm mob siab rau lawv tus kheej rau cov nkoj hluav taws xob, yog siv cov roj teeb lithium-ion roj teeb saib xyuas (BMS) nrog tib yam. thawj chav kawm zoo.
Qhov zoo tshaj plaws BMS yuav raug kho raws li qhov teeb meem kev teeb tsa, thaum qhov phem tshaj BMS yuav tsuas yog kev tiv thaiv ntxhib kom tsis txhob muaj kev puas tsuaj tag.
Yog tias koj lub hom phiaj yog kom muaj kev nyab xeeb, txhim khu kev qha thiab ruaj khov lub zog cia ntawm lub nkoj, tsis txhob sim txuag qee cov nyiaj ntawm BMS.
Tab sis yuav ua rau muaj teeb meem loj dua, nyob rau hauv cov ntaub ntawv ntawm lithium-ion li, nyob rau hauv lub sij hawm ntev, siv pheej yig, tsis zoo tsim Cheebtsam yuav tsis tsuas nkim nyiaj ntau, tab sis kuj yuav ua rau muaj teeb meem loj hluav taws nyob rau hauv lub nkoj.
Lub roj teeb LiFePO4 tau tshaj tawm tias yog qhov zoo tshaj plaws "plug-in" hloov roj teeb-acid yam tsis tas yuav muaj cov khoom siv them nyiaj ntxiv.
Nws tau hais tias yuav tsum tau sib xws nrog tag nrho cov lead-acid chargers thiab DC-rau-DC converters tam sim no nyob rau hauv kev ua lag luam.Lawv muaj BMS built-in uas tuaj yeem saib xyuas thiab tswj lawv cov kev them nyiaj thiab tso tawm kom muaj kev nyab xeeb siab tshaj plaws, kev ntseeg siab thiab lub neej ntev.
LiFePO4 yog 35% sib zog dua li cov roj lead-acid sib npaug thiab 40% me me.Nws muaj peev xwm tawm tau siab (<1kW / 120A), 1C tus nqi thiab muaj peev xwm muab tau txog 2,750 cycles hauv qab 90% DoD, lossis txog li 5,000-50%.% Ualub voj voog.
Lub tuam txhab Dutch Victron paub txog nws cov khoom siv hluav taws xob zoo, muab 60-300Ah muaj peev xwm "plug-in" LFP roj teeb, haum rau 12.8 lossis 25.6V kev teeb tsa, thaum tawm mus rau 80% ntawm DoD lossis txog li 5,000 cycles, nws tuaj yeem muab 2,500 Tsuas yog 50% ib lub voj voog.
Cov cim npe ntse txhais tau hais tias lawv tuaj yeem siv qhov sib xyaw Bluetooth module rau kev saib xyuas cov chaw taws teeb, tab sis lawv xav tau ib qho sab nraud Victron VE.Bus BMS.
Qhov kev tso tawm tam sim no yog 100A ib 100Ah, thiab qhov siab tshaj plaws ntawm cov roj teeb nyob rau hauv parallel yog 5.
Cov plug-in hloov LFP roj teeb no muaj BMS built-in thiab lub tshuab hluav taws xob tshwj xeeb kom txias lub roj teeb thaum nws them.
Lub IHT "plug-in" 100Ah LiFePo4 roj teeb los ntawm lub npe nrov LFP Hom Sib Tw Yug hauv Tebchaws Meskas tuaj yeem lees txais 1C them thiab 100A tawm tam sim no (200A ncov hauv 3 vib nas this) yam tsis muaj kev puas tsuaj.
Lawv kuj suav nrog BMS uas muaj peev xwm tswj tau qhov ntsuas hluav taws xob, ntsuas kub, roj teeb tshuav, thiab muab kev tiv thaiv luv luv.
Firefly's proprietary thev naus laus zis suav nrog cov pa roj carbon monoxide ua npuas ncauj nrog ntau txhiab lub hlwb qhib uas faib cov sulfuric acid electrolyte thoob plaws cheeb tsam los txhim kho kev ua haujlwm ntawm txhuas-acid chemistry.
Lub "microbattery" nyob rau hauv cov pa roj carbon ua npuas dej electrolyte qauv tuaj yeem ua tiav qhov kev tso tawm ntau dua tam sim no, ua kom lub zog ntom ntom thiab txuas ntxiv lub neej voj voog (<3x).
Nws kuj tseem tso cai rau kev them nyiaj sai dua piv rau cov roj teeb txhuas-acid ib txwm, uas yog qhov zoo tshaj plaws thaum them nyiaj los ntawm lub sijhawm them nyiaj tsawg xws li hnub ci lossis alternator.
Fireflies tsis tshua muaj resistant rau sulfate thiab tuaj yeem siv nrog cov txheej txheem ntau theem txhuas-acid chargers thiab alternator regulators.
Nyob rau hauv cov sib sib zog nqus nqus iav fiber lev (AGM) roj teeb, cov pa roj carbon cathode tau hais kom nce nqi txais, yog li ua kom ceev cov txheej txheem them nyiaj, ua kom muaj ntau lub voj voog muaj thiab txo qhov kev puas tsuaj ntawm daim hlau.
Lub roj teeb siv lead ua yog lub kaw cov kua qaub (SLA) uas siv lub zog tshiab, tsis muaj corrosive SiO2 acid electrolyte uas yuav crystallize lub sijhawm, ua kom muaj zog thiab txhim kho kev ua haujlwm.
Lub high-purity lead-calcium-selenium electrode phaj thiab electrolyte yog khaws cia nyob rau hauv lub microporous ncoo, yog li lub roj teeb lub sij hawm them ceev yog ob zaug ntawm cov pa SLA, qhov paug yog ntxaum, lub voj voog ntau zaus, thiab nws yog siv ntau dua. Qhov kub thiab txias tshaj lithium-ion roj teeb thiab muab kev ua tau zoo dua Ntau lwm AGMs muaj lub neej ua haujlwm ntev dua.

Duncan Kent tau kawm txog cov thev naus laus zis uas siv hauv cov roj teeb lithium thiab piav qhia cov xwm txheej los txiav txim siab thaum sib piv nrog kev tswj hwm ...
Siv cov thev naus laus zis no uas tsis muaj cadmium lossis antimony, cov roj teeb siv lead ua tuaj yeem rov ua dua mus txog 99%, thiab tseem ceeb tshaj, nws raug cais raws li kev thauj mus los tsis zoo.
