Nrog rau qhov kev thov nce ntxiv los ntawm cov neeg siv khoom rau kev them nqi ceev ntawm lub tsheb hluav taws xob, ultrafast charging thev naus laus zis tau dhau los ua qauv hauv kev lag luam. Hauv kev pom ntawm kev lag luam sab hauv, nrog rau kev siv loj ntawm cov roj teeb them ceev thiab kev koom tes ntawm cov tsheb thiab cov chaw them nqi, cov neeg siv khoom yuav maj mam farewell rau "them kev ntxhov siab".
Kev txhim kho lub zog rov ua kom zoo dua qub
Nrog rau kev nce ntau ntawm cov tsheb tshiab zog, cov neeg siv kev ntxhov siab txog mais tau txo qis. Txawm li cas los xij, nyob rau hauv cov nqe lus ntawm kev siv lub zog ntxiv, lub zog tshiab lub tsheb them tsis tuaj yeem ua tiav qhov ceev tib yam li refueling. Daim ntawv dawb 2022 ntawm Kev Coj Tus Cwj Pwm ntawm Tuam Tshoj Hluav Taws Xob Cov Neeg Siv Hluav Taws Xob tso tawm los ntawm Tuam Tshoj Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob qhia tau hais tias tam sim no, qhov nruab nrab ib zaug them lub sijhawm ntawm Suav cov neeg siv tsheb hluav taws xob yog 49.3 feeb, nrog rau 1.4 nqi ib hnub.
Txhawm rau txhim kho kev them nyiaj ceev ntawm lub tsheb fais fab thiab txhim kho cov neeg siv kev paub dhau los, ntau lub tuam txhab roj teeb tseem ceeb tam sim no txhawb kev txhim kho cov roj teeb hluav taws xob.
Kev hloov kho tshiab ntawm roj teeb kev ua tau zoo
Ji Xuehong, Tus Thawj Coj ntawm Automotive Industry Innovation Research Center ntawm North China University of Technology, tau hais rau cov neeg sau xov xwm, "Cov roj teeb them ceev sawv cev rau txoj kev loj hlob ntawm cov roj teeb fais fab yav tom ntej. Tam sim no, cov khoom siv hluav taws xob tshiab, tshwj xeeb tshaj yog cov qauv nruab nrab mus rau siab kawg, yuav tsum tau ua. yuav nruab nrog ultra ceev them roj teeb thiab 800V high-voltage charging platforms yav tom ntej, nrog rau kev txhim kho cov cuab yeej thiab kev sib tw sib tw ntawm cov tuam txhab tsheb, lawv yuav maj mam npog ib nrab mus rau qis-kawg qauv.
Tam sim no, kev them nyiaj ceev ceev tau maj mam dhau los ua tus qauv hauv high-end tshiab lub zog tsheb qauv, thiab kev them nyiaj ceev thev naus laus zis kuj tau dhau los ua qhov tshiab ntawm kev sib tw tsom rau cov tuam txhab roj teeb hluav taws xob. Txawm li cas los xij, cov neeg sab hauv kev lag luam taw qhia tias lub peev xwm them ceev ceev ntawm cov roj teeb nyob ntawm qhov ceev lithium ntxig muaj peev xwm ntawm qhov tsis zoo electrode ntawm lub roj teeb ntawm tes thiab lub peev xwm tswj thermal ntawm lub roj teeb. Cov roj teeb uas muaj kev them nyiaj ceev yuav tsum ua kom muaj kev sib tw ntxiv hauv cov ntaub ntawv, qauv, txheej txheem tsim khoom, thiab lwm yam.
Nws yog ib qho tsim nyog sau cia tias lub zog hluav taws xob ceev ceev tuaj yeem ua kom sov lub roj teeb sai, yog li kev tswj xyuas thermal ntawm cov roj teeb hluav taws xob yog qhov tseem ceeb heev. Ji Xuehong tau hais tias, "Rau cov khoom siv roj teeb nrawm nrawm rau lawv tus kheej, qhov kev sib tw tseem ceeb tseem yog los ntawm cov roj teeb kub dhau thaum lub sijhawm them ceev ceev. Cov tuam txhab roj teeb yuav tsum muaj cov qauv tsim hluav taws xob tshiab thiab siv cov khoom siv tshiab kom ntseeg tau tias roj teeb muaj kev nyab xeeb thiab lifespan."
Nyob rau tib lub sijhawm, Liu Kai, Tus Lwm Thawj Coj ntawm Lub Tsev Haujlwm Saib Xyuas Kev Ua Haujlwm ntawm Tuam Tshoj Association of Automobile Manufacturers thiab Tus Thawj Coj ntawm Tuam Tshoj Charging Alliance, yav dhau los tau hais rau cov neeg sau xov xwm tias qhov nyuaj ntawm lub zog hluav taws xob ceev ceev rau cov roj teeb hluav taws xob yog qhov ntsuas qhov txo qis. Lub zog ntom ntom thiab tus nqi nce ntxiv ntawm lub roj teeb system tshwm sim los ntawm kev ntsuas coj los tiv thaiv kev khiav tawm thermal.
Tsim kom muaj ib qho ecosystem tiav
Hais txog kev txhim kho cov roj teeb ceev ceev los ntawm cov tuam txhab muaj feem cuam tshuam, Ji Xuehong ntseeg tias: "Tam sim no, lub zog roj teeb thev naus laus zis tau nrawm nrawm dua, thiab cov tuam txhab tsheb muaj kev xav tau ntau rau cov roj teeb them ceev ceev. Cov tuam txhab roj teeb yuav tsum ua kom cov hauj lwm ntawm cov cuab yeej technology siab, ua kom muaj zog. cov khoom lag luam kom ua tiav kev nyab xeeb thiab tus nqi qis, tuav lub sijhawm kom phim nrog cov tuam txhab muag tsheb loj tshaj plaws thiab kev siv cov khoom lag luam tseem ceeb heev rau cov tuam txhab roj teeb.
Nyob rau hauv qhov kev pom ntawm kev lag luam sab hauv, nrog kev txhim kho txuas ntxiv ntawm kev tsim kho vaj tse txhawb kev sib koom ua ke ntawm kev tsim tsheb thiab kev tsim hluav taws xob, nws xav tias cov thev naus laus zis tshiab thiab cov haujlwm xws li 800V high-voltage fast charging yuav ua kom lawv tsaws hauv 2024. Raws li tsab ntawv ceeb toom los ntawm Huaan Securities, nws xav tias los ntawm 2025, qhov kev thov rau 3C lossis siab dua cov roj teeb uas txhawb nqa high-voltage ceev them yuav ncav cuag 350GWh, suav txog 59% ntawm lub zog hluav taws xob hauv tsev fais fab roj teeb ntim; Nyob rau hauv 2026, qhov muag ntim ntawm high-voltage platform qauv saum toj no 800V yuav ncav cuag 5.8 lab units, nrog ib tug nkag mus ntawm 50%.
Cov ntaub ntawv tshawb fawb ntawm CITIC Securities tau taw qhia tias nws xav tias tag nrho kev nkag mus ntawm cov roj teeb ceev ceev yuav txhawb kev txhim kho thiab kev loj hlob ntawm cov ntaub ntawv muaj feem xyuam, thiab coj cov peev txheej rau cov khoom siv carbon dub, anode txheej cov ntaub ntawv, LiFSI, aerogel, composite collector, aramid txheej, thermal conductive kheej kheej txhuas, polyurethane, rwb thaiv tsev cov ntaub ntawv, thiab lwm yam.
Txawm li cas los xij, kev txhim kho ntawm kev them nqi hluav taws xob tsis yog nyob ntawm lub roj teeb nkaus xwb. Txhawm rau kom ua tiav "kev them nyiaj sai zoo li kev siv roj" uas cov neeg siv khoom xav tau, nws yog qhov yuav tsum tau sib koom tes thiab txhim kho cov roj teeb, tsheb, thiab cov chaw them nyiaj. Tam sim no, ntau lub tuam txhab tsheb tshiab hauv tsev, suav nrog Xiaopeng, Jike, Zhiji, Zoo, thiab Zero Run, tau tshaj tawm 800V cov qauv kev them nyiaj ceev ceev. Nyob rau tib lub sij hawm, kev tsim kho ntawm overcharging pawg kuj nyob rau hauv tag nrho viav vias.
"Cov roj teeb them ceev kuj tseem xav tau kev txhawb nqa kev them nqi, thiab cov khoom siv hluav taws xob siab yuav tsum tau them nqi thiab ua kom zoo rau kev teeb tsa. Qhov kev faib ua feem ntawm kev teeb tsa thiab cov cuab yeej siv rau qhov sib txawv ntawm daim ntawv thov yuav tsum tau txiav txim siab los ntawm kev lag luam pom." Ji Xuehong tau hais tias kev them nyiaj ceev thev naus laus zis yog kev txhim kho kev lag luam, tab sis nws txoj kev txhim kho tseem muaj cov txheej txheem mus. Thaum cov txheej txheem no, cov tuam txhab tsim tsheb, cov tuam txhab roj teeb hluav taws xob, cov neeg them nyiaj, thiab cov tuam txhab hluav taws xob yuav tsum tau koom tes nrog ib leeg kom tso tawm qhov kev them nyiaj sai sai, txhawm rau muab cov neeg siv khoom kom yooj yim thiab ceev lub zog ntxiv.
