5-feeb them nrog ntau yam ntawm 400 km! Thaum Lub Peb Hlis 17th, BYD tau tshaj tawm nws "megawatt flash charging" system, uas yuav ua rau lub tsheb hluav taws xob tau them sai sai li refueling.
Txawm li cas los xij, txhawm rau ua tiav lub hom phiaj ntawm "roj thiab hluav taws xob ntawm tib lub nrawm", BYD zoo li tau mus txog qhov txwv ntawm nws tus kheej lithium hlau phosphate roj teeb. Txawm tias muaj tseeb hais tias lub zog ceev ntawm lithium hlau phosphate cov khoom nws tus kheej mus txog nws theoretical txwv, BYD tseem thawb cov khoom tsim thiab thev naus laus zis optimization mus rau qhov kawg.
Ua si rau qhov kawg! 10C lithium hlau phosphate
Ua ntej, raws li cov ntaub ntawv tshaj tawm ntawm BYD lub rooj sib tham xov xwm, BYD's flash charging technology siv cov khoom hu ua "flash charging blade battery", uas tseem yog hom lithium hlau phosphate roj teeb.
Qhov no tsis tsuas yog rhuav tshem cov kev tswj hwm ntawm cov roj teeb lithium siab xws li cov roj teeb siab nickel ternary hauv kev lag luam ceev ceev, tab sis kuj tso cai rau BYD los thawb qhov kev ua tau zoo ntawm lithium hlau phosphate mus rau qhov hnyav dua, cia BYD txuas ntxiv nws cov nqi lag luam hauv txoj kev siv tshuab ntawm lithium hlau phosphate roj teeb.
Raws li cov ntaub ntawv tso tawm los ntawm BYD, BYD tau ua tiav lub siab tshaj plaws them lub zog ntawm 1 megawatt (1000 kW) rau qee cov qauv xws li Han L thiab Tang L, thiab lub teeb nyem ntawm 5 feeb tuaj yeem ntxiv 400 mais ntawm ntau yam. Nws 'flash charging' roj teeb tau mus txog tus nqi them ntawm 10C.
Lub tswvyim no yog dabtsi? Raws li cov qauv kev tshawb fawb, tam sim no tau lees paub hauv kev lag luam tias lub zog ceev ntawm lithium hlau phosphate roj teeb nyob ze rau qhov kev txwv. Feem ntau, txhawm rau kom ntseeg tau tias muaj zog ntau dua, cov tuam ntxhab yuav txi qee yam ntawm lawv cov nqi thiab kev ua haujlwm tawm. Feem ntau, 3-5C tso tawm yog suav tias yog qhov zoo tshaj plaws paug tus nqi rau lithium hlau phosphate roj teeb.
Txawm li cas los xij, lub sijhawm no BYD tau nce qhov tso tawm ntawm lithium hlau phosphate mus rau 10C, uas tsis tsuas yog txhais tau tias tam sim no tau ze li ob npaug, tab sis kuj txhais tau hais tias qhov kev tiv thaiv sab hauv thiab kev tswj xyuas thermal tau nce ob npaug.
BYD hais tias raws li lub hauv paus ntawm cov hniav, BYD's "flash charging battery" optimizes electrode qauv ntawm cov hniav roj teeb, txo cov kev tsiv teb tsaws tsis kam ntawm lithium ions los ntawm 50%, yog li ua tiav cov nqi them tshaj 10C thawj zaug.
Ntawm cov khoom siv electrode zoo, BYD siv high-purity, high-pressure, thiab high-density plaub tiam lithium hlau phosphate cov ntaub ntawv, nrog rau nanoscale crushing txheej txheem, tshwj xeeb formula additives, thiab high-kub calcination txheej txheem. Ib qho zoo nkauj sab hauv siv lead ua qauv thiab luv luv diffusion txoj kev rau lithium ions nce tus nqi tsiv teb tsaws ntawm lithium ions, yog li txo cov roj teeb sab hauv thiab txhim kho qhov kev ua haujlwm tawm.
Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm kev xaiv tsis zoo electrodes thiab electrolytes, nws tseem yuav tsum tau xaiv qhov zoo tshaj plaws los ntawm qhov zoo tshaj plaws. Daim ntawv thov ntawm cov khoom siv graphite nrog cov cheeb tsam tshwj xeeb siab dua thiab ntxiv cov kev ua haujlwm siab PEO (polyethylene oxide) electrolytes kuj tau dhau los ua cov xwm txheej tsim nyog los txhawb 10C lithium hlau phosphate roj teeb.
Hauv luv luv, txhawm rau ua tiav kev ua tiav, BYD tsis muaj nuj nqis. Ntawm lub rooj sib tham xov xwm, tus nqi ntawm BYD Han L EV nruab nrog lub "flash charging" roj teeb tau mus txog 270000-350000 yuan, uas yog ze li ntawm 70000 yuan siab dua tus nqi ntawm nws 2025 EV ntse tsav tsheb version (701KM Honor qauv).
Lub neej ntev thiab kev nyab xeeb ntawm flash charging roj teeb yog dab tsi?
Ntawm chav kawm, rau high-tech, ua kim tsis yog ib qho teeb meem. Txhua tus neeg tseem muaj kev txhawj xeeb txog qhov zoo thiab kev nyab xeeb ntawm cov khoom.Hais txog qhov no, Lian Yubo, Tus Lwm Thawj Coj ntawm BYD Group, tau hais tias cov roj teeb them hluav taws xob tuaj yeem tuav lub neej ntev txawm tias thaum them tus nqi ultra-siab, nrog rau 35% nce hauv roj teeb lub neej.
Nws tuaj yeem hais tau tias BYD cov lus teb rau lub sijhawm no yog qhov ncaj ncees thiab muaj kev txawj ntse, yam tsawg kawg tsis lees paub qhov cuam tshuam ntawm overcharging ntawm roj teeb lub neej.
Vim hais tias nyob rau hauv txoj cai, them sai sai thiab tso tawm yuav muaj irreversible cuam tshuam rau lub roj teeb qauv. Qhov ceev ntawm kev them nqi thiab kev tso tawm sai, qhov cuam tshuam ntau dua ntawm lub roj teeb lub neej. Raws li rau supercharging, kev siv mus sij hawm ntev feem ntau txo cov roj teeb lub neej los ntawm 20% mus rau 30%. Yog li ntawd, feem ntau manufacturers pom zoo kom overcharge raws li ib qho kev xaiv thaum muaj xwm ceev them.
Qee cov tuam ntxhab yuav qhia txog kev them nyiaj ntau dhau los ntawm kev txhim kho lub voj voog lub neej ntawm lub roj teeb nws tus kheej. Kev txo cov roj teeb lub neej tshwm sim los ntawm overcharging yog offset los ntawm kev nce hauv roj teeb lub neej los ntawm cov chaw tsim khoom, thaum kawg tso cai rau tag nrho cov khoom kom tswj tau cov kev them nyiaj zoo thiab kev ua haujlwm tawm hauv nws qhov kev cia siab.
Tsis tas li ntawd, txhawm rau ua kom tiav "flash charging", BYD kuj tau siv cov txheej txheem hloov kho tshiab nyob ib puag ncig cov teeb meem ntawm lithium hlau phosphate roj teeb thiab tag nrho cov khoom siv hluav taws xob.
Txhawm rau kom them nyiaj rau qhov tsis txaus ntawm qhov ua tau zoo ntawm qhov kub thiab txias hauv cov roj teeb lithium hlau phosphate, BYD's "flash charging" system qhia txog cov khoom siv hluav taws xob cua sov kom tswj tau qhov kev them nqi sai thiab kev ua haujlwm ntawm lub roj teeb los ntawm nws tus kheej cua sov hauv qhov chaw txias. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv lub roj teeb cua sov los ntawm kev them nyiaj siab thiab kev tso tawm, lub roj teeb chav tsev yog kev sib xyaw nrog cov kua dej txias txias, uas ncaj qha tshem tawm cov roj teeb hluav taws xob los ntawm cov tub yees.
Hais txog kev nyab xeeb kev ua tau zoo, lithium hlau phosphate tau rov ua pov thawj nws tus nqi. Raws li BYD, nws "flash charging" hniav roj teeb tau yooj yim dhau 1200 tuj crushing xeem thiab 70km / h kev sib tsoo. Cov qauv tshuaj ruaj khov thiab cov nplaim hluav taws kub nyhiab ntawm lithium hlau phosphate ib zaug ntxiv muab qhov tseem ceeb tshaj plaws rau kev nyab xeeb ntawm lub tsheb hluav taws xob.
Tig lub hwj chim ntsaws
Tej zaum cov neeg feem coob tsis muaj lub tswv yim ntawm megawatt theem fais fab, tab sis nws yog ib qho tseem ceeb kom nkag siab tias 1 megawatt tej zaum yuav yog lub hwj chim ntawm lub Hoobkas nruab nrab, lub peev xwm nruab ntawm lub hnub ci hluav taws xob me me, lossis kev siv hluav taws xob hauv zej zog ntawm ib txhiab tus neeg.
Yog lawm, koj hnov lawm. Lub zog them ntawm lub tsheb yog sib npaug ntawm lub Hoobkas lossis thaj chaw nyob. Ib qhov chaw nres tsheb supercharging yog sib npaug rau kev siv hluav taws xob ntawm ib nrab ntawm txoj kev. Qhov ntsuas ntawm kev siv hluav taws xob no yuav yog ib qho kev sib tw loj heev rau daim phiaj hluav taws xob hauv nroog tam sim no.
Nws tsis yog tias tsis muaj nyiaj los tsim cov chaw them nqi, tab sis txhawm rau tsim cov chaw them nyiaj super, nws yog ib qho tsim nyog yuav tsum tau kho dua tshiab tag nrho lub nroog thiab txoj kab hluav taws xob. Ib yam li ua dumplings tshwj xeeb rau lub phaj ntawm vinegar, qhov project no yuav tsum tau siv zog ntau. Nrog nws lub zog tam sim no, BYD tsuas yog npaj kev tsim kho ntau dua 4000 "megawatt flash charging stations" thoob tebchaws yav tom ntej.
4000 'megawatt flash charging stations' yeej tsis txaus. Flash charging " roj teeb thiab "flash charging" tsheb tsuas yog thawj kauj ruam ntawm kev ua tiav "cov roj thiab hluav taws xob ntawm tib qhov ceev".
Nrog rau kev tawg ntawm hluav taws xob tsheb thiab roj teeb thev naus laus zis, qhov teeb meem tiag tiag tau pib hloov mus rau kev tsim kho cov chaw siv hluav taws xob thiab lub zog sib txuas. Ob leeg BYD thiab CATL, nrog rau lwm lub tuam txhab roj teeb thiab hluav taws xob tsheb hauv Suav teb, yuav ntsib kev lag luam ntau dua hauv qhov no.
