Vim li cas lub tsheb fais fab xav tau 800V?

Ob lub tuam txhab thiab cov tswv tsheb npau suav ntawm cov txiaj ntsig ntawm "them rau 5 feeb thiab tsav tsheb 200km".

Yuav kom ua tiav cov txiaj ntsig no, ob qhov kev xav tau loj thiab qhov mob yuav tsum tau daws:
Ib qho, nws yog txhawm rau txhim kho kev them nqi zoo thiab ua kom lub roj teeb them ceev ceev.
Qhov thib ob, nws yog txhawm rau txhim kho kev ua haujlwm ntawm tag nrho lub tsheb thiab txuas ntxiv kev tsav tsheb hauv tib lub zog.
Ntawm no, peb tuaj yeem siv lub tsev kawm ntawv qib siab physics kom nkag siab luv luv: P = UI. Yog li yog tias koj xav nce lub zog, tsuas muaj ob txoj hauv kev los nce qhov tam sim no lossis nce qhov voltage.
Txawm li cas los xij, cov dej ntws loj yuav ua rau muaj kev kub ntxhov hauv cov phom sij, cov kab hluav taws xob thiab cov khoom tseem ceeb ntawm cov roj teeb hluav taws xob, thiab qhov kev txwv siab ntawm kev txhim kho theoretical tsis loj. Yog li ntawd, txoj kev nce mus rau tam sim no yog "tsis tuaj yeem ncav cuag", tsis yog, nws yuav tsum yog "tsis deb heev".
Yog li, ua li cas txog kev nce qhov voltage?
Thaum lub kaw lus tam sim no tseem nyob tas li, lub zog them nyiaj yuav ob npaug raws li qhov system voltage, uas yog, lub ncov them ceev yuav muab ob npaug, thiab lub sijhawm them nyiaj yuav luv heev. Tsis tas li ntawd, nyob rau hauv tib lub zog them, yog tias qhov hluav taws xob siab dua, qhov tam sim no tuaj yeem txo qis, thiab cov xaim tsis tas yuav tsum yog tuab heev, thiab kev siv hluav taws xob tiv thaiv hluav taws xob ntawm cov hlau kuj raug txo.

Yog li ntawd, yog tias koj tseem siv tus thawj 400V them cable loj, koj tuaj yeem nce lub zog them nyiaj. Qhov no txhais tau hais tias nyob rau hauv 800V platform, thinner charging cables tuaj yeem siv tau.
Huawei kev tshawb fawb qhia tau hais tias kev them nyiaj ceev ceev siv 800V high-voltage hom txhawb nqa lub zog siab tshaj plaws ntawm 30%-80% SOC, thaum qis-voltage high-tam sim no hom tsuas tuaj yeem ua lub zog siab tshaj plaws ntawm 10% -20% SOC, thiab lub zog them nyiaj. poob ntau heev nyob rau hauv lwm yam. ceev. Nws tuaj yeem pom tias 800V high-voltage hom tuaj yeem txhawb kev them nyiaj sai dua.
Kev ua haujlwm siab dua ntawm tag nrho lub tsheb, uas txhais tau hais tias nyob rau hauv qhov xwm txheej ntawm qhov tam sim no, lub roj teeb hluav taws xob ntau dua, lub zog ntawm lub cev muaj zog ntau dua, thiab qhov ua tau zoo ntawm lub cev muaj zog ntau dua.
Yog li ntawd, 800V high-voltage platform tuaj yeem ua tiav lub zog siab thiab lub zog, nrog rau kev ua kom nrawm dua. Txawm hais tias kev txhim kho hauv kev siv hluav taws xob ntxiv tau coj los ntawm 800V rau lub tsheb hluav taws xob yog qhov zoo, ib qho ntawm cov teeb meem loj tshaj plaws rau kev siv 800V yog qhov teeb meem nqi.
