Diversified powertrain electrification paths

Nws tau nkag siab tias nrog kev txhim kho txuas ntxiv ntawm kev siv hluav taws xob txuag hluav taws xob, qhov nruab nrab ntawm cov roj siv tam sim no ntawm cov neeg nrog caij tsheb tshiab hauv Suav teb tseem poob qis, thiab nws yog ze rau lub hom phiaj tus nqi ntawm 5L ib 100 km hauv 2020. Tam sim no, a coob tus compression ratios (12-13) + Miller voj voog tau siv. + Cov khoom siv hloov pauv hloov pauv + kev sib txhuam tsis zoo thiab lwm yam thev naus laus zis txuag hluav taws xob, cov thermal efficiency ntawm roj av cav maj mam nce mus txog qib siab thoob ntiaj teb ntawm 40%; qhov kev faib ua feem ntawm kev sib kis tsis siv neeg tau mus txog ntau dua 70%, 7DCT thiab 8AT tau ua tiav ntau lawm; CVT, CVT180, CVT250 successively Mass ntau lawm.

Txawm li cas los xij, ntsib lub neej yav tom ntej nrog cov qauv siv hluav taws xob nruj dua, nws tseem nyuaj rau ua tau raws li cov qauv yooj yim los txhim kho cov thermal efficiency ntawm roj av xyaw. Wang Binggang, tus thawj coj ntawm National New Energy Vehicle Innovation Project Expert Group, tau hais hauv kev xam phaj nrog Gasgoo tias nyob rau hauv kev pom ntawm kuv lub teb chaws cov xwm txheej, ntau hom tsheb siv tshuab thiab hom hluav taws xob tsim nyog dua. Thaum txhim kho kev siv hluav taws xob ntawm cov tsheb, nws yog ib qho tsim nyog yuav tsum tau muab qhov tseem ceeb rau kev txhim kho cov tsheb ib txwm muaj. Kev hloov pauv. Yog li ntawd, pawg kws tshaj lij tau pom zoo tias nyob rau hauv 15 xyoo tom ntej no, cov tsheb tsoos Suav yuav raug hloov pauv mus rau hauv cov qauv hybrid.

Cov thev naus laus zis tseem ceeb rau kev siv hluav taws xob muaj zog ntau dua

Raws li ib tug muab kev daws teeb meem rau powertrain electrification, SAIC Transmission tau tsim ib tug high-speed thiab sib sib zog nqus choj hluav taws xob. Raws li Lu Jibo, tus thawj coj saib xyuas kev ua haujlwm ntawm Shanghai Automotive Transmission Co., Ltd., qhov no yog tus choj peb-hauv-ib tus tsav uas paub txog kev sib sib zog nqus ntawm kev kub ceev, kev kub ceev ruaj khov hlau nplaum synchronous motors thiab siab. -Kev tswj hwm kev ua haujlwm MCU kev koom ua ke. Qhov siab tshaj plaws ntawm cov tsav tsheb tuaj yeem ncav cuag 16000rpm; lub reducer yog tsim thiab tsim raws li cov kev cai ntawm German Volkswagen MEB. Lub zog siab tshaj plaws tuaj yeem ncav cuag 165KW, lub siab tshaj plaws torque yog 300Nm, thiab lub zog ntawm lub log kawg mus txog 3900Nm. Nyob rau tib lub sijhawm, tus tsav tsav tau muab faib ua lub zog siab thiab qis. Version, tus reducer tuaj yeem siv qhov sib txawv ntawm qhov sib txawv, thiab tuaj yeem siv ntau yam qauv xws li SUVs thiab tsheb.

Muaj peev xwm ua lag luam zeem muag rau powertrain electrification

Rau powertrain, txawm hais tias yuav muaj ntau yam kev sib tw ntawm txoj kev mus rau hluav taws xob, qhov kev ua lag luam nrog kev loj hlob muaj peev xwm tseem tsim nyog rau txhua tus neeg lub siab nyiam.

Cov ntaub ntawv muag khoom tam sim no qhia tau hais tias thaum Lub Kaum Hli 2020, kev muag khoom muag ntawm cov tsheb thauj neeg mob tshiab tau tshaj 144,000, ib xyoos ib zaug nce ntawm 119.8% thiab ib hlis-rau-lub hlis nce ntawm 15.9%. Nrog rau kev rov qab los ntawm lub zog tshiab tsheb lag luam pom tseeb, tag nrho cov neeg caij tsheb lag luam tau pib rov zoo. "Peb tau saib tag nrho cov ntaub ntawv pov hwm thiab cov chaw muag khoom. Txij li Lub Xya Hli, qhov kev loj hlob ntawm tag nrho cov lag luam tau nce siab tshaj 100%, uas qhia tau tias lub zog tshiab kev lag luam tau ua rau kev loj hlob ntawm kev muag khoom tag nrho."

Duan Zhihui, National New Energy Vehicle Technology Innovation Center, uas tau ua raws li kev tshawb fawb thiab kev loj hlob ntawm cov tshuab hluav taws xob hybrid, tseem qhia nws qhov kev xav zoo ntawm kev ua lag luam hybrid. Nws tau nkag siab tias tam sim no muaj ntau dua 90 hom hybrid systems nyob hauv tsev thiab txawv teb chaws, cov uas ntau lub hauv paus muaj zog sib cais, series thiab sib npaug, thiab P2 lossis P2.5. Peb cov thev naus laus zis no muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. "Thaum cov tuam txhab muaj zog tsim cov thev naus laus zis thev naus laus zis, tsis txhob yuam kev los ntawm lub tswv yim tsis raug thiab xaiv txoj hauv kev tsis zoo." Duan Zhihui thov rov hais dua.
