Yog tias lub tsheb fais fab architecture raug hloov kho mus rau 800V, cov qauv ntawm nws cov khoom siv hluav taws xob siab yuav raug tsa raws li qhov ntawd, thiab lub inverter kuj tseem yuav raug hloov los ntawm cov khoom siv IGBT ib txwm mus rau cov khoom siv SiC MOSFET. Tus nqi ntawm lub inverter nws tus kheej yog qhov thib ob tsuas yog cov khoom siv roj teeb. Yog tias koj hloov kho mus rau SiC, tus nqi yuav nce mus rau lwm qib.
Tab sis rau OEMs, daim ntawv thov ntawm silicon carbide feem ntau tsis yog tsuas yog xav txog tus nqi ntawm cov khoom siv fais fab xwb, tab sis qhov tseem ceeb dua, qhov kev hloov pauv ntawm tag nrho lub tsheb. Yog li ntawd, nws yog ib qho tseem ceeb kom nrhiav tau qhov sib npaug ntawm cov nyiaj txuag los ntawm SiC thiab nws cov nqi siab.
Hais txog SiC, thawj tus neeg sim nws yog Tesla.
Xyoo 2018, Tesla tau hloov IGBT modules nrog silicon carbide modules thawj zaug hauv Model 3. Ntawm tib theem zog, qhov loj ntawm pob ntawm silicon carbide modules yog me dua li ntawm silicon modules, thiab kev poob hloov pauv raug txo los ntawm 75%. Ntxiv mus, yog tias hloov pauv, siv SiC modules es tsis txhob IGBT modules tuaj yeem ua rau lub kaw lus ua haujlwm tau zoo dua li 5%.
Los ntawm qhov kev xam pom ntawm tus nqi, tus nqi hloov pauv tau nce ze li ntawm 1,500 yuan. Txawm li cas los xij, vim yog kev txhim kho ntawm kev siv tsheb zoo, lub peev xwm ntawm lub roj teeb tau raug txo qis, txuag cov nqi ntawm sab roj teeb.
Qhov no suav tau tias yog kev twv txiaj loj rau Tesla. Nws cov khoom lag luam loj heev ua rau tus nqi tsis nce siab. Tesla kuj tau siv qhov kev twv txiaj loj no los txeeb cov thev naus laus zis thiab kev lag luam ntawm 400V roj teeb.
Hais txog 800V, Porsche tau ua tus thawj coj hauv kev teeb tsa lub tsheb ua si Taycan uas siv hluav taws xob tag nrho nrog lub kaw lus 800V hauv xyoo 2019, ua rau muaj kev sib tw ua riam phom rau 800V high-voltage architecture ntawm cov tsheb hluav taws xob.
Muaj qee yam "tsis tsim nyog" txog kev tshuaj xyuas cov nqi los ntawm lub zeem muag ntawm Porsche. Tom qab tag nrho, nws tsom mus rau qhov cuam tshuam ntawm lub tsheb khoom kim heev thiab tsom mus rau qhov zoo ntawm lub hom.
Tiam sis hais txog kev tsim kho thev naus laus zis thiab kev siv, qhov no yog ib qho project loj uas cuam tshuam rau tag nrho lub cev. Piv txwv li, nyob rau hauv 800V high-voltage charging, lub voltage ntawm lub roj teeb pob yuav tsum tau nce mus txog 800V, txwv tsis pub nws yuav raug hlawv vim yog lub zog them tam sim no loj. Tsis tas li ntawd, nws tsis yog tsuas yog cuam tshuam rau lub kaw lus them nqi xwb, tab sis kuj tseem cuam tshuam rau lub roj teeb system, lub tshuab tsav hluav taws xob, cov khoom siv high-voltage thiab cov xov hlau harness system, cuam tshuam rau kev pib, kev tsav tsheb, kev siv cua txias ntawm lub tsheb, thiab lwm yam.
