Vim li cas cov tsheb fais fab thiaj xav tau 800V?

Ob leeg cov chaw tsim khoom thiab cov tswv tsheb npau suav txog qhov cuam tshuam ntawm "them nqi rau 5 feeb thiab tsav tsheb 200km".

Yuav kom ua tiav qhov txiaj ntsig no, yuav tsum daws ob qho kev xav tau tseem ceeb thiab cov teeb meem mob:
Ib, nws yog los txhim kho qhov kev ua haujlwm them nqi thiab ua kom lub roj teeb them ceev dua.
Qhov thib ob, nws yog los txhim kho kev ua haujlwm zoo ntawm tag nrho lub tsheb thiab nthuav dav qhov kev tsav tsheb hauv qab tib lub zog.
Ntawm no, peb tuaj yeem siv cov physics hauv tsev kawm ntawv theem siab kom nkag siab luv luv: P = UI. Yog li ntawd, yog tias koj xav kom lub zog nce ntxiv, tsuas muaj ob txoj hauv kev los ua kom tam sim no nce lossis ua kom lub zog hluav taws xob nce ntxiv.
Txawm li cas los xij, cov hluav taws xob loj yuav ua rau muaj kev poob cua sov ntau hauv cov phom them, cov xov hlau thiab cov khoom tseem ceeb ntawm cov roj teeb fais fab, thiab qhov txwv siab tshaj plaws ntawm kev txhim kho theoretical tsis loj. Yog li ntawd, txoj kev mus rau kev nce hluav taws xob yog "tsis ncav cuag", tsis yog, nws yuav tsum "tsis deb heev".
Yog li, yuav ua li cas txog kev nce lub zog?
Thaum lub zog tam sim no ntawm lub cev tseem ruaj khov, lub zog them yuav ob npaug raws li lub zog hluav taws xob ntawm lub cev, uas yog, qhov ceev them siab tshaj plaws yuav ob npaug, thiab lub sijhawm them yuav luv dua. Tsis tas li ntawd, nyob rau hauv tib lub zog them, yog tias lub zog hluav taws xob siab dua, tam sim no tuaj yeem txo qis, thiab cov hlau tsis tas yuav tuab heev, thiab kev siv hluav taws xob tiv thaiv cua sov ntawm cov hlau kuj raug txo qis.

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