Tus phooj ywg siv, ntev lub neej voj voog
Piv nrog rau cov khoom siv hluav taws xob zoo tib yam thiab cov pa hluav taws xob ceev / super charging pawg, cov khoom ua kua-txias super charging pawg tsis tsuas yog them sai dua, tab sis kuj muaj ntau yam zoo. "Lub foob pob hluav taws xob ntawm Huawei lub siab ua kua-txias supercharger yog lub teeb heev, thiab txawm tias cov poj niam lub tsheb uas muaj zog me me tuaj yeem siv tau yooj yim, tsis zoo li yav dhau los them phom uas loj heev." Zhou Xiang, tus tswv lub tsheb fais fab hauv Chongqing, tau hais.
"Kev siv cov thev naus laus zis tshiab, cov ntaub ntawv tshiab, thiab cov tswv yim tshiab muab cov khoom ua kua-txias supercharging pawg kom zoo uas cov pa hluav taws xob tsis tuaj yeem ua rau yav dhau los." Hu Fenglin tau hais tias rau tag nrho cov kua-txias supercharging pawg, tam sim no thiab lub zog muaj ntau dua Loj txhais tau tias them sai dua. Feem ntau, cov cua kub ntawm lub charger cable yog proportional rau square ntawm tam sim no. Qhov ntau dua qhov them tam sim no, qhov cua sov ntawm lub cable ntau dua. Txhawm rau txo cov cua sov uas tsim los ntawm lub cable thiab tsis txhob overheating, qhov chaw hla ntawm cov hlau yuav tsum tau nce ntxiv, uas txhais tau hais tias cov phom them nyiaj thiab cov khoom siv hluav taws xob hnyav dua. Lub siab ua kua-txias supercharger daws qhov teeb meem ntawm cov cua sov thiab siv cov cables nrog cov chaw me me los xyuas kom muaj kev sib kis ntawm cov dej loj. Yog li ntawd, cov cables ntawm tag nrho cov kua-txias supercharging pawg yog nyias thiab sib zog dua li cov pa supercharging pawg, thiab cov phom them kuj sib dua. Piv txwv li, cov phom them ntawm NIO cov kua-txias supercharging pawg tsuas yog hnyav 2.4 kilograms, uas yog sib zog dua li cov pa hluav taws xob. Cov pawg yog sib zog ntau dua thiab coj cov neeg siv kev paub zoo dua, tshwj xeeb tshaj yog rau cov poj niam cov tswv tsheb, uas yooj yim dua rau kev siv.
"Qhov zoo ntawm cov kua-txias supercharging pawg yog tias lawv muaj kev nyab xeeb dua." Wei Dong tau hais tias yav dhau los, feem ntau cov khoom siv hluav taws xob siv hluav taws xob cua txias, cua txias thiab lwm txoj hauv kev, uas yuav tsum tau muaj qhov cua hauv qhov chaw ntawm cov pawg them nyiaj, uas ua rau tsis muaj huab cua sib xyaw nrog cov hmoov av, txawm tias cov hlau zoo, tshuaj tsuag ntsev. thiab dej vapor nkag mus rau sab hauv ntawm pawg them nyiaj thiab yog adsorbed rau ntawm qhov chaw ntawm cov khoom siv hluav taws xob, ua rau muaj teeb meem xws li kev ua haujlwm tsis zoo ntawm cov rwb thaiv tsev, tsis muaj cua sov dissipation, txo cov nqi them, thiab cov khoom siv lub neej luv. Hauv qhov sib piv, cov txheej txheem ua kua ua kom txias tuaj yeem ua tiav tag nrho, txhim kho kev rwb thaiv tsev thiab kev nyab xeeb, thiab ua kom cov pawg them nyiaj mus txog qib siab dua ntawm plua plav thiab dej tsis zoo nyob ib puag ncig thoob ntiaj teb cov qauv hluav taws xob IP65, nrog kev ntseeg siab dua. Tsis tas li ntawd, tom qab tso tseg cov cua txias ntau lub kiv cua tsim, lub suab nrov ntawm lub siab ua kua-txias supercharging pawg tau raug txo kom tsawg, los ntawm 70 decibels ntawm cov cua txias rau pawg mus txog 30 decibels, uas yog ze rau ib tug ntxhi. , zam qhov kev xav tau ntawm kev them nyiaj ceev hauv thaj chaw nyob yav dhau los. Muaj ib qho kev txaj muag ntawm kev tsis txaus siab vim lub suab nrov thaum hmo ntuj.
Cov nqi qis dua thiab cov nqi rov qab luv dua kuj yog ib qho zoo ntawm cov kua-txias supercharged pawg. Zeng Xin tau hais tias cov txheej txheem cua txias cua txias feem ntau muaj lub neej ntev tsis tshaj 5 xyoos, tab sis cov sijhawm xauj tsev tam sim no rau kev ua haujlwm ntawm chaw them nqi feem ntau yog 8 txog 10 xyoo, uas txhais tau hais tias tsawg kawg yuav tsum tau rov ua lag luam thaum lub sijhawm ua haujlwm. ntawm qhov chaw nres tsheb. Hloov cov khoom siv thawj zaug. Lub neej kev pab cuam ntawm cov kua-txias them tag nrho yog ntau tshaj 10 xyoo. Piv txwv li, lub neej tsim ntawm Huawei lub siab ua kua-txias super charging pawg yog ntau tshaj 15 xyoo, uas tuaj yeem npog tag nrho lub neej voj voog ntawm chaw nres tsheb. Tsis tas li ntawd, piv nrog cov khoom siv hluav taws xob uas siv cov cua txias uas yuav tsum tau qhib lub txee rau kev tshem tawm cov plua plav thiab kev saib xyuas, tag nrho cov kua-txias them cov pawg tsuas yog yuav tsum tau yaug tom qab cov plua plav accumulates hauv lub tshuab hluav taws xob sab nraud, ua haujlwm yooj yim.
Ua ke, tag nrho lub neej voj voog tus nqi ntawm lub siab ua kua-txias supercharger yog qis dua li cov khoom siv cua txias. Nrog rau daim ntawv thov thiab kev nce qib ntawm cov kua-txias super-them pawg, nws cov txiaj ntsig zoo ntawm cov nqi yuav dhau los ua pom tseeb dua.

Kev ua lag luam muaj qhov ci ntsa iab thiab kev sib tw ua kom sov
Qhov tseeb, nrog kev nce zuj zus ntawm kev nkag mus ntawm cov tsheb tshiab lub zog thiab kev txhim kho sai ntawm kev txhawb nqa cov txheej txheem xws li them pawg, tag nrho cov kua-txias supercharging pawg tau dhau los ua qhov tseem ceeb ntawm kev sib tw hauv kev lag luam. Ntau lub tuam txhab tsheb fais fab tshiab, cov tuam txhab them cov tuam txhab, cov tuam txhab thev naus laus zis, thiab lwm yam tau pib tshawb fawb thiab kev tsim kho thiab kev teeb tsa ntawm cov khoom ua kua-txias supercharging.
Tesla yog thawj lub tuam txhab tsheb hauv kev lag luam los xa cov kua-txias supercharging pawg hauv cov khoom siv. Nws cov V3 supercharging pawg tau txais kev tsim ua kua-txias tag nrho, ua kua-txias them modules thiab cov phom ua kua-txias. Qhov siab tshaj plaws them lub zog ntawm ib rab phom yog 250kW. Nws tau tshaj tawm tias Tesla tau maj mam xa cov tshiab V4 tag nrho cov kua-txias supercharging chaw nres tsheb thoob ntiaj teb txij li xyoo tas los. Asia thawj qhov chaw nres tsheb V4 supercharging tau tsim tawm hauv Hong Kong, Tuam Tshoj, thaum Lub Kaum Hli xyoo tas los, thiab yuav nkag mus rau hauv lub lag luam loj. Nws tau tshaj tawm tias qhov theoretical siab tshaj plaws them lub zog ntawm pawg them nyiaj no yog 615kW, uas yog sib npaug rau kev ua haujlwm ntawm Huawei thiab NIO cov kua-txias supercharging pawg. Nws zoo nkaus li tias kev sib tw ua lag luam rau cov khoom ua kua-txias tag nrho tau pib ntsiag to.
"Feem ntau hais lus, tag nrho cov kua-txias superchargers muaj peev xwm them lub zog siab, thiab kev them nyiaj tau zoo dua qub, uas tuaj yeem txo cov neeg siv kev ntxhov siab." Hauv kev xam phaj nrog tus neeg sau xov xwm los ntawm Tuam Tshoj Automotive Xov Xwm, nws hais tias, txawm li cas los xij, tam sim no tag nrho cov kua-txias superchargers Overcharging pawg tau txwv hauv daim ntawv teev npe, ua rau cov nqi siab dua. Tsis tas li ntawd, txij li kev them nqi hluav taws xob siab yuav tsum tau ua kom zoo dua lub roj teeb kev nyab xeeb kev tswj hwm thiab ua kom lub tsheb voltage platform, tus nqi kuj tseem yuav nce 15% mus rau 20%. Zuag qhia tag nrho, txoj kev loj hlob ntawm high-power charging technology yuav tsum muaj kev xav txog cov yam xws li kev tswj xyuas kev nyab xeeb ntawm lub tsheb, kev ywj pheej ntawm cov khoom siv hluav taws xob siab, thiab tus nqi. Qhov no yog ib kauj ruam ntawm kauj ruam.
"Tus nqi siab dua ntawm cov kua-txias supercharging pawg yog ib qho ntawm cov teeb meem uas cuam tshuam nws txoj kev nce qib loj." Hu Fenglin tau hais tias tam sim no tus nqi ntawm txhua Huawei supercharging pawg yog kwv yees li 600,000 yuan. Nyob rau theem no, cov lag luam me thiab nruab nrab feem ntau koom nrog kev them nyiaj ua lag luam Nws yuav luag nyuaj rau kev sib tw. Txawm li cas los xij, nyob rau hauv txoj kev loj hlob mus ntev, nrog rau kev nthuav dav ntawm daim ntawv thov thiab txo cov nqi, ntau qhov zoo ntawm cov kua-txias supercharged pawg yuav maj mam ua qhov tseem ceeb. Qhov kev thov nruj ntawm cov neeg siv khoom thiab kev lag luam rau kev nyab xeeb, kev kub ceev thiab kev them nyiaj ceev yuav coj qhov chaw dav rau kev txhim kho cov kua-txias supercharging pawg.
Daim ntawv tshaj tawm kev tshawb fawb tsis ntev los no tau tshaj tawm los ntawm CICC tau taw qhia tias cov kua dej txias dhau los ua rau kev txhim kho ntawm cov saw hlau, thiab kev lag luam hauv tsev yuav tsum ncav cuag ze li ntawm 9 billion yuan hauv 2026. Tsav los ntawm cov tuam txhab tsheb, tuam txhab hluav taws xob, thiab lwm yam., nws yog thawj zaug xav tias tus naj npawb ntawm cov chaw ua dej txias hauv tsev yuav ncav cuag 45,000 hauv 2026.
Zeng Xin kuj tau taw qhia tias xyoo 2021, yuav muaj tsawg dua 10 tus qauv hauv kev ua lag luam hauv tsev uas txhawb nqa nyiaj dhau; nyob rau hauv 2023, yuav muaj ntau tshaj 140 qauv uas txhawb nqa overcharging, thiab yuav muaj ntau dua yav tom ntej. Qhov no tsis yog tsuas yog ib qho kev xav tiag tiag ntawm kev nrawm nrawm ntawm tib neeg txoj haujlwm thiab lub neej hauv kev ntxiv zog rau lub zog tshiab, tab sis kuj qhia txog kev txhim kho ntawm kev xav tau ntawm kev lag luam. Vim li no, txoj kev loj hlob zeem muag ntawm tag nrho cov kua-txias super-them pawg tau zoo heev.
