Lub tsev sab hauv ntawm lub tsheb yog ua los ntawm ntau cov khoom siv, tshwj xeeb yog cov khoom siv hluav taws xob tshwj xeeb. Lub hom phiaj ntawm lub voltage platform yog kom phim lub zog ntawm cov khoom sib txawv. Qee qhov yuav tsum muaj cov khoom siv hluav taws xob tsawg, xws li cov khoom siv hluav taws xob hauv lub cev, cov khoom siv lom zem, thiab lwm yam (feem ntau yog 12v voltage platform mov), thiab qee qhov yuav tsum muajHEEV NTSUG, xws li cov roj teeb tshuab, siab Voltage drive tshuab, them nyiaj tshuab, thiab lwm yam. (400v), yog li muaj cov hluav taws xob siab thiab lub tshuab hluav taws xob tsawg.
Tom qab ntawd qhia meej txog kev sib raug zoo ntawm 800V thiab super ceev them: Tam sim no cov khoom siv roj teeb hluav taws xob ntau dua li 400v roj teeb, yog tias qhov hluav taws xob hluav taws xob tau nce, nws txhais tau tias Nyob rau hauv tib lub zog siv zog, qhov tam sim no tuaj yeem txo los ntawm ib nrab, tag nrho cov txheej txheem ploj zuj zus, tab sis kuj tseem ceeb dua, lub tsheb ua tau zoo heev.
Qhov tseeb, kev them nyiaj nrawm tsis ncaj qha rau 800V, feem ntau vim tias kev them nyiaj ntau dua, uas yog li tes hluavtaws ntau dua, tab sis nws tseem tuaj yeem ua tiav super sai them nyob rau hauv daim ntawv ntawm siab tam sim no. Tab sis 800v yog kom ua tiav lub zog hluav taws xob muab lub hauv paus zoo, vim tias tib yam kom ua tiav 450V, nws xav tau 900A, 900A hauv cov kev pabcuam technical tam sim no rau cov neeg caij tsheb yuav luag tsis yooj yim sua. Yog li, nws yog qhov tsim nyog dua li link 800v thiab super them nyiaj ncaj ncees ua ke, hu ua 800v super them nyiaj thev naus laus zis.
Tam sim no, muaj peb homHigh-voltageCov qauv txheej txheem uas yuav tsum tau ua kom tiav lub siab ceev ceev, thiab cov kev siv hluav taws xob siab yuav tsum tau dhau los ua cov tseem ceeb:
(1) Lub cev hluav taws xob puv qhov hluav taws xob, uas yog, 800v fais fab roj teeb + 800v Obc, PDU + 800V Cua txias, PTC.
Cov txiaj ntsig zoo: Kev hloov pauv siab dua tshiab, piv txwv, lub zog hloov pauv ntawm DC / DC yog 92%, nws tsis tsim nyog rau kev tawm tsam los ntawm DC / DC, lub system hluav taws xob hloov pauv hloov pauv yog 90% × 92% = 82.8%.
Kev tsis muaj zog: Tus architecture tsis tsuas yog muaj qhov siab yuav tsum tau hloov los ntawm Si-bastric , Lub sijhawm luv lub tsheb xaus kev nce nqi nce siab dua, tab sis nyob rau hauv lub sijhawm ntev, tom qab cov saw muaj thiab cov nplai ua tiav. Qhov ntim ntawm qee qhov yog txo, lub zog hluav taws xob tau txhim kho, thiab tus nqi ntawm lub tsheb yuav poob.
(2) ib feem ntawm Phau Ntawv MaumoosHEEV NTSUG, uas yog, 800v roj teeb + 400v Tsav, Tswj Hluav Taws Xob + 400v Obc, DC, PDU + 400v Cua txias, PTC.
Qhov Zoo: Yeej siv cov qauv uas twb muaj lawm, tsuas yog hloov kho lub zog roj teeb, tus nqi ntawm lub tsheb xaus kev hloov pauv yog qhov me me, thiab muaj cov lus qhia me me hauv lub sijhawm luv luv.
Qhov tsis zoo: DC / DC theem-down yog siv nyob rau ntau qhov chaw, thiab lub zog ploj yog loj.
(3) Txhua qhov qis-voltage architecture, uas yog, roj teeb 400v (rub tawm 400 dc, dc, PDU + 400v cua txias, PTC.
Cov txiaj ntsig zoo: Lub tsheb xaus kev hloov pauv yog me me, roj roj tsuas yog xav tau BMS hloov.
Qhov tsis zoo: Kev nce qib ntxiv, roj teeb nce ntxiv, siv cov roj teeb qub, kev txhim kho ntawm kev them nyiaj tau zoo.
