Kev ntxhov siab ntau yog qhov loj tshaj plaws hauv lub fwj txwv tsis pub muaj kev vam meej ntawm kev lag luam tsheb hluav taws xob, thiab lub ntsiab lus tom qab ua tib zoo tshuaj xyuas ntawm ntau qhov kev ntxhov siab yog "short endurance" thiab "slow charging". Tam sim no, ntxiv rau lub roj teeb lub neej, nws yog qhov nyuaj rau kev ua tiav, yog li "ceev ceev" thiab "supercharge" yog qhov tseem ceeb ntawm kev teeb tsa tam sim no ntawm ntau lub tuam txhab tsheb. Yog li ntawd cov800V high voltageplatform tau los ua.
Rau cov neeg siv khoom zoo tib yam, 800V high-voltage platform txhawb nqa los ntawm cov tuam txhab tsheb tsuas yog cov lus qhia, tab sis raws li cov thev naus laus zis tseem ceeb yav tom ntej, nws kuj tseem cuam tshuam rau cov neeg siv khoom siv tsheb, thiab peb yuav tsum muaj kev nkag siab dav dav ntawm cov cuab yeej tshiab no. . Yog li ntawd, daim ntawv no yuav ua qhov kev ntsuam xyuas qhov tob ntawm 800V high-pressure platform los ntawm ntau yam xws li hauv paus ntsiab lus, kev thov, kev loj hlob thiab kev tsaws.
Vim li cas koj thiaj xav tau 800V platform?
Nyob rau hauv ob xyoos dhau los, nrog rau kev maj mam nce ntawm cov tsheb hluav taws xob, tus naj npawb ntawm cov pawg them nyiaj tau nce ib txhij, tab sis pawg pawg tsis tau txo qis. Thaum kawg ntawm xyoo 2020, "car-pile ratio" ntawm cov tsheb tshiab lub zog hauv tsev yog 2.9: 1 (tus naj npawb ntawm cov tsheb yog 4.92 lab thiab tus lej ntawm cov nqi them yog 1.681 lab). Xyoo 2021, qhov piv ntawm lub tsheb rau pawg yuav yog 3: 1, uas yuav tsis txo qis tab sis nce ntxiv. Qhov tshwm sim yog tias lub sijhawm queue ntev dua lub sijhawm them.
Tom qab ntawd, nyob rau hauv cov ntaub ntawv ntawm tus naj npawb ntawm cov pawg them tsis tuaj yeem khaws cia, txhawm rau txo lub sijhawm ua haujlwm ntawm cov pawg them nyiaj, kev them nyiaj ceev ceev yog qhov tsim nyog heev.
Qhov kev nce hauv kev them ceev tuaj yeem nkag siab yooj yim raws li qhov nce ntawm lub zog them, uas yog, P = U·I hauv P (P: charging power, U: charging voltage, I: charging current). Yog li ntawd, yog tias koj xav ua kom lub zog them nyiaj ntau dua, khaws ib qho ntawm qhov voltage lossis tam sim no tsis hloov pauv, nce qhov voltage lossis tam sim no tuaj yeem txhim kho lub zog them. Cov kev taw qhia ntawm lub high voltage platform yog los txhim kho lub charger efficiency ntawm lub tsheb kawg thiab paub lub ceev recharge ntawm lub tsheb kawg.
Lub 800V platformrau cov tsheb hluav taws xob yog qhov kev xaiv tseem ceeb rau kev them nyiaj ceev. Rau cov roj teeb fais fab, kev them ceev ceev yog qhov tseem ceeb los ua kom lub zog tam sim no ntawm lub xov tooj ntawm tes, tseem hu ua tus nqi them tus nqi; Tam sim no, ntau lub tuam txhab tsheb nyob rau hauv qhov kev teeb tsa ntawm 1000 mais ntawm kev tsav tsheb, tab sis tam sim no lub roj teeb thev naus laus zis, txawm tias nws tau tsim los rau cov roj teeb uas muaj zog, nws kuj xav tau lub zog roj teeb pob nrog ntau tshaj 100kWh, uas yuav ua rau ib qho kev nce ntawm cov cell, yog tias lub mainstream 400V platform tseem siv tau, tus naj npawb ntawm cov cell sib npaug nce, uas ua rau muaj kev nce tsheb npav tam sim no. Nws coj kev sib tw zoo rau tooj liab hlau specification thiab cov yeeb nkab cua sov.
Yog li ntawd, nws yog ib qho tsim nyog los hloov cov qauv sib luag ntawm cov roj teeb hauv cov roj teeb pob, txo qhov sib npaug thiab ua kom cov koob, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Txawm li cas los xij, raws li tus naj npawb ntawm series nce, lub roj teeb pob kawg voltage yuav nce ntxiv. Qhov hluav taws xob xav tau rau 100kWh roj teeb pob kom ua tiav 4C ceev ceev yog li 800V. Yuav kom ua tau raws li kev them nyiaj ceev ntawm txhua theem ntawm cov qauv, 800V hluav taws xob architecture yog qhov kev xaiv zoo tshaj plaws.
