Them 5 feeb nrog qhov deb ntawm 400 kilometers! Thaum Lub Peb Hlis 17, BYD tau tso tawm nws lub "megawatt flash charging", uas yuav ua rau cov tsheb fais fab them sai npaum li kev ntxiv roj.
Txawm li cas los xij, txhawm rau kom ua tiav lub hom phiaj ntawm "roj thiab hluav taws xob tib lub sijhawm", BYD zoo li tau mus txog qhov txwv ntawm nws lub roj teeb lithium iron phosphate. Txawm hais tias qhov tseeb tias lub zog ceev ntawm cov khoom siv lithium iron phosphate nws tus kheej tab tom mus txog nws qhov kev txwv theoretical, BYD tseem tab tom thawb cov khoom tsim thiab kev txhim kho thev naus laus zis mus rau qhov kawg.
Ua si kom kawg! 10C lithium hlau phosphate
Ua ntej, raws li cov ntaub ntawv tshaj tawm ntawm BYD lub rooj sib tham xov xwm, BYD lub tshuab them hluav taws xob siv cov khoom hu ua "flash charging blade battery", uas tseem yog hom roj teeb lithium iron phosphate.
Qhov no tsis yog tsuas yog rhuav tshem qhov kev tswj hwm ntawm cov roj teeb lithium siab xws li cov roj teeb nickel ternary siab hauv kev lag luam them ceev, tab sis kuj tso cai rau BYD thawb qhov kev ua tau zoo ntawm lithium hlau phosphate mus rau qhov siab tshaj plaws dua, tso cai rau BYD txuas ntxiv nws cov nqi lag luam hauv txoj kev siv tshuab ntawm cov roj teeb lithium hlau phosphate.
Raws li cov ntaub ntawv tso tawm los ntawm BYD, BYD tau ua tiav lub zog them siab tshaj plaws ntawm 1 megawatt (1000 kW) rau qee cov qauv xws li Han L thiab Tang L, thiab kev them ceev ceev ntawm 5 feeb tuaj yeem ntxiv 400 kilometers ntawm ntau yam. Nws lub roj teeb 'flash charging' tau mus txog qhov them ceev ntawm 10C.
Lub tswv yim no yog dab tsi? Hauv cov ntsiab lus ntawm kev tshawb fawb, tam sim no nws tau lees paub hauv kev lag luam tias lub zog ceev ntawm cov roj teeb lithium iron phosphate yog ze rau qhov kev txwv theoretical. Feem ntau, txhawm rau kom ntseeg tau tias muaj zog ceev dua, cov chaw tsim khoom yuav txi qee qhov ntawm lawv cov kev ua haujlwm them thiab tso tawm. Feem ntau, 3-5C tso tawm yog suav tias yog qhov tso tawm zoo tshaj plaws rau cov roj teeb lithium iron phosphate.
Txawm li cas los xij, lub sijhawm no BYD tau nce tus nqi tso tawm ntawm lithium hlau phosphate mus rau 10C, uas tsis yog tsuas yog txhais tau tias tam sim no tau yuav luag ob npaug, tab sis kuj txhais tau tias qhov kev tiv thaiv sab hauv thiab qhov nyuaj tswj kev kub tau ob npaug.
BYD hais tias raws li lub hauv paus ntawm cov hniav, BYD's "flash charging battery" ua kom zoo dua cov qauv electrode ntawm lub roj teeb hniav, txo qhov kev tiv thaiv kev tsiv teb tsaws chaw ntawm lithium ions los ntawm 50%, yog li ua tiav tus nqi them ntau dua 10C thawj zaug.
Ntawm cov khoom siv electrode zoo, BYD siv cov khoom siv lithium hlau phosphate tiam plaub uas muaj kev ntshiab siab, siab siab, thiab siab ceev, nrog rau cov txheej txheem nanoscale crushing, cov tshuaj ntxiv tshwj xeeb, thiab cov txheej txheem calcination kub siab. Cov qauv siv lead ua sab hauv zoo meej dua thiab txoj kev sib kis luv dua rau lithium ions ua rau cov lithium ions tsiv teb tsaws chaw ntau dua, yog li txo cov roj teeb sab hauv tsis kam thiab txhim kho kev ua haujlwm ntawm cov roj teeb.
Tsis tas li ntawd xwb, hais txog kev xaiv cov electrodes tsis zoo thiab electrolytes, nws tseem yog qhov tsim nyog los xaiv qhov zoo tshaj plaws los ntawm qhov zoo tshaj plaws. Daim ntawv thov ntawm cov graphite dag nrog thaj chaw tshwj xeeb siab dua thiab ntxiv cov electrolytes PEO (polyethylene oxide) ua tau zoo kuj tau dhau los ua cov xwm txheej tsim nyog los txhawb 10C lithium hlau phosphate roj teeb.
Hauv ntej, txhawm rau kom ua tiav qhov kev ua tau zoo tshaj plaws, BYD tsis tseg nyiaj ntau. Ntawm lub rooj sib tham xov xwm, tus nqi ntawm BYD Han L EV uas muaj lub roj teeb "flash charging" tau mus txog 270000-350000 yuan, uas yog ze li ntawm 70000 yuan siab dua tus nqi ntawm nws 2025 EV tsav tsheb ntse version (701KM Honor qauv).
Lub neej thiab kev nyab xeeb ntawm cov roj teeb flash charging yog dab tsi?
Tau kawg, rau cov khoom siv thev naus laus zis siab, kev kim tsis yog teeb meem. Txhua tus neeg tseem 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 ceev ceev tuaj yeem ua haujlwm ntev txawm tias them ntawm tus nqi siab heev, nrog rau 35% nce ntxiv hauv lub neej voj voog roj teeb.
Nws tuaj yeem hais tias BYD cov lus teb lub sijhawm no yog qhov ncaj ncees thiab muaj kev txawj ntse, tsawg kawg tsis tsis lees paub qhov cuam tshuam ntawm kev them ntau dhau rau lub roj teeb lub neej.
Vim tias hauv paus ntsiab lus, kev them sai thiab tso tawm sai yuav muaj cov teebmeem tsis rov qab rau cov qauv roj teeb. Qhov ceev ntawm kev them thiab tso tawm sai dua, qhov cuam tshuam ntau dua rau lub neej voj voog ntawm lub roj teeb. Raws li kev them ceev, kev siv ntev feem ntau txo lub neej roj teeb los ntawm 20% txog 30%. Yog li ntawd, feem ntau cov chaw tsim khoom pom zoo kom them ntau dhau ua qhov kev xaiv them thaum muaj xwm txheej ceev.
Muaj ib txhia chaw tsim khoom yuav siv lub roj teeb uas them ntau dhau los ua kom lub roj teeb siv tau ntev dua. Yog tias lub roj teeb siv tau ntev dua, lub tuam txhab yuav pab kom lub roj teeb siv tau ntev dua, thiab thaum kawg yuav ua rau lub roj teeb siv tau ntev dua thiab siv tau ntev dua.
Tsis tas li ntawd xwb, txhawm rau kom ua tiav "kev them ceev ceev", BYD kuj tau siv ntau yam kev hloov kho dua tshiab nyob ib puag ncig qhov tsis zoo ntawm cov roj teeb lithium hlau phosphate thiab tag nrho cov khoom siv fais fab.
Yuav kom them tau qhov tsis zoo ntawm kev ua haujlwm kub qis hauv cov roj teeb lithium iron phosphate, BYD lub "flash charging" system qhia txog lub tshuab cua sov pulse kom tswj tau qhov kev them thiab tso tawm sai ntawm lub roj teeb los ntawm kev ua kom sov tus kheej hauv qhov chaw txias. Tib lub sijhawm, txhawm rau daws qhov kub ntawm lub roj teeb los ntawm kev them thiab tso tawm fais fab siab, lub roj teeb tau koom ua ke nrog lub tshuab tswj kub txias ua kua sib xyaw, uas ncaj qha tshem tawm lub roj teeb cua sov los ntawm cov tub yees.
Hais txog kev ua tau zoo ntawm kev nyab xeeb, lithium iron phosphate tau ua pov thawj dua nws qhov txiaj ntsig. Raws li BYD, nws lub roj teeb "flash charging" tau yooj yim dhau qhov kev sim tsoo 1200 tuj thiab kev sib tsoo 70km / h. Cov qauv tshuaj ruaj khov thiab cov khoom tiv thaiv hluav taws ntawm lithium iron phosphate ib zaug ntxiv muab qhov kev lees paub tseem ceeb tshaj plaws rau kev nyab xeeb ntawm cov tsheb fais fab.
Ntsib qhov teeb meem ntawm kev them nqi
Tej zaum feem ntau cov neeg tsis muaj lub tswv yim ntawm lub zog megawatt, tab sis nws yog ib qho tseem ceeb kom nkag siab tias 1 megawatt tej zaum yuav yog lub zog ntawm lub Hoobkas nruab nrab, lub peev xwm teeb tsa ntawm lub chaw tsim hluav taws xob hnub ci me me, lossis kev siv hluav taws xob ntawm cov zej zog ntawm ib txhiab tus neeg.
Yog, koj hnov yog lawm. Lub zog them ntawm lub tsheb yog sib npaug rau lub Hoobkas lossis thaj chaw nyob. Lub chaw nres tsheb supercharging yog sib npaug rau kev siv hluav taws xob ntawm ib nrab txoj kev. Qhov ntsuas hluav taws xob no yuav yog qhov kev sib tw loj rau lub zog hluav taws xob hauv nroog tam sim no.
Tsis yog hais tias tsis muaj nyiaj los tsim cov chaw them hluav taws xob, tab sis los tsim cov chaw them hluav taws xob loj, nws yog qhov tsim nyog los kho dua tshiab tag nrho lub nroog thiab txoj kev lub zog hluav taws xob. Ib yam li ua cov khoom noj txom ncauj tshwj xeeb rau ib lub tais ntawm cov kua txiv hmab, qhov project no xav tau ntau yam kev siv zog. Nrog nws lub zog tam sim no, BYD tsuas yog npaj rau kev tsim ntau dua 4000 "megawatt flash charging stations" thoob plaws lub 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 mus rau kev ua tiav "roj thiab hluav taws xob ntawm tib qhov ceev".
Nrog rau kev tshawb pom tshiab hauv kev siv tshuab fais fab thiab roj teeb, qhov teeb meem tiag tiag tau pib hloov mus rau kev tsim cov chaw tsim hluav taws xob thiab cov tes hauj lwm fais fab. Ob leeg BYD thiab CATL, nrog rau lwm lub tuam txhab roj teeb thiab tsheb fais fab hauv Suav teb, tej zaum yuav ntsib cov cib fim ua lag luam ntau dua hauv qhov no.
