BMW Plans EV Battery Dominance With New Gen6 Cylindrical Cell

Internal combustion tsheb yog txhua yam hais txog lub cav, tab sis rau cov tsheb fais fab lub roj teeb yog qhov tseem ceeb tshaj plaws. BMW tau meej meej coj qhov no mus rau lub siab nrog nws cov tiam tom ntej roj teeb platform, ib feem ntawm hluav taws xob Neue Klasse yuav los txog rau xyoo 2025. BMW Gen6 roj teeb system aims kom lub tuam txhab ua tus thawj coj nyob rau hauv ntau yam, efficiency, thiab nqi. Kuv hnov ​​​​cov ntsiab lus tseem ceeb ntawm BMW's Sustainability Through Innovation Day hauv Munich lub lim tiam no.

Qhov kev hloov pauv loj tshaj plaws yuav yog hloov mus rau cylindrical hlwb. Txog tam sim no, BMW tau siv cov roj teeb prismatic hauv nws cov pob. Cov hlwb lawv tus kheej yuav txuas ntxiv siv NMC chemistry thiab yuav tsim los ntawm cov neeg koom tes uas twb muaj lawm CATL thiab EVE. Lub hom phiaj ntawm lub xov tooj ntawm tes tshiab, tsis yog qhov xav tsis thoob, yog txhawm rau txhim kho lub zog ceev, txo lub sijhawm them nyiaj, thiab pab kom ntau kWh tau ntim rau hauv tib qhov chaw. BMW kuj cia siab tias yuav txo qis emissions ntawm nws cov khoom. Tab sis kev txhim kho tus lej loj tshaj plaws yuav raug nqi.

Cov roj teeb tam sim no siv li ntawm 40% ntawm tus nqi ntawm BMW EV (raws li lub tuam txhab, raws li daim duab no ntawm tus nqi ntawm lub tuam txhab. i4), uas yog sib npaug nrog rau lwm yam kev lag luam. Nrog rau Gen6 platform, BMW yog lub hom phiaj kom txo qis tus nqi ntawm nws cov roj teeb pob, uas yuav ua rau nws cov EVs sib tw ncaj qha ntawm tus nqi nrog nws cov tsheb sib xyaw nrog (ICE) tsheb. Nrog rau qhov no, lub zog ceev yuav nce 20% (tso ntau lub zog hauv tib lub pob loj), lub sijhawm them nyiaj yuav raug txo los ntawm 30%, thiab cov hlwb tshiab yuav ua rau BMW lub tsheb sab saum toj muab 30% ntau ntxiv.

Ntau yam tsis ua pov thawj tias yog qhov teeb meem rau BMW EVs li nws yog. BMW i4 eDrive40 cog lus tias muaj kev sib tw 365 mais (WLTP) thiab txawm tias qhov kev ua tau zoo ntawm M50 version boasts 315 mais. Lub WLTP ntau yam rau iX SUV ncua ntawm 257 mais rau xDrive40 txog 380 mais rau xDrive50. Ntxiv 30% rau cov duab saum toj kawg nkaus thiab koj yuav tau txais 475 mais ntawm ntau yam rau yav tom ntej BMW i4 eDrive40 thiab zoo kawg 494 mais rau yav tom ntej iX xDrive50. Txhua tus neeg uas muaj kev them nyiaj hauv tsev yuav tsis siv cov kev sib txuas hauv zej zog ntau zaus yog tias lawv muaj ntau yam no.

Cov kws tshuaj xyuas tau pom tias BMW lub tsheb ua tau zoo piv rau lawv cov kev ntaus nqi, tab sis lub tuam txhab tau tsom mus rau kev txhim kho kev ua haujlwm ntxiv. Nyob rau ntawm Sustainability Through Innovation Day, BMW tau piav qhia tias nrog Gen6 platform nws yuav tshem tawm qhov muaj txiaj ntsig Wh ntawm kev siv hluav taws xob los ntawm kev ua kom zoo rau thaj chaw tseem ceeb ntawm lub tsheb. EV-tshwj xeeb aerodynamics yuav txuag tau 5Wh / km, optimized log tsheb ntxiv 5Wh / km, powertrain efficiency 15Wh / km, 4Wh / km yuav los ntawm cov ntaub ntawv sib zog txuag lub tsheb hnyav, thiab lwm 4Wh / km yuav muab tau los ntawm kev txhim kho log bearings thiab EV. - tshwj xeeb nres. Thaum koj xav txog qhov ua tau zoo EV tuaj yeem tswj hwm 4 mais ib kWh, lossis 250Wh ib mais (156Wh / km), kev txuag tag nrho ntawm 33Wh / km yuav ntxiv ntau qhov tseem ceeb. Qhov no tuaj yeem qhib ntau li 20% ntau dua.

Txhawm rau tsim cov roj teeb tshiab, BMW tab tom yuav tsim rau rau lub chaw tsim khoom tshiab thoob ntiaj teb nrog nws cov neeg koom tes CATL thiab EVE, nyob rau saum tsib lub Hoobkas uas nws tau ua haujlwm tam sim no. Ob ntawm cov no yuav nyob hauv Suav teb, ob qho hauv Tebchaws Europe, thiab ob qho hauv Asmeskas, Mexico lossis Canada. Txhua tus yuav tuaj yeem tsim tau txog 20GWh ntawm cov roj teeb ib xyoos. Lub hom phiaj txo qis CO2 ntawm 60% yuav ua tiav los ntawm kev siv ib feem pua ​​​​ntawm cov khoom siv thib ob (recycled) rau cov lithium, cobalt, thiab npib tsib xee hauv cov roj teeb, nrog rau lub zog ntsuab thaum lub sijhawm tsim khoom. Qhov tseeb, BMW lub hom phiaj ua kom nws cov roj teeb tsim ua kom tag nrho (ib yam dab tsi Tesla kuj tau tshaj tawm ntawm nws Hnub Roj Teeb 2020).

BMW cylindrical hlwb yuav muaj 46mm txoj kab uas hla zoo li Tesla ntau-vaunted 4680 ib yam nkaus, tab sis muaj nyob rau hauv ob qhov siab ntawm 95mm thiab 125mm, ob qho tib si siab dua Tesla lub 80mm hlwb. Raws li twb tau sau tseg lawm, BMW yuav lo nrog NMC chemistry es tsis hloov mus rau qhov nrov Lithium Iron Phosphate (LFP), txawm hais tias qhov no yuav yog qhov kev xaiv nrog Gen6 thev naus laus zis. Txawm li cas los xij, cov ntsiab lus nickel yuav nce ntxiv thaum cov ntsiab lus cobalt yuav txo qis hauv cathodes, nrog cov ntsiab lus silicon ntau dua ntawm cov anodes. Qhov no yog li cas qhov 20% nce hauv volumetric zog ceev yuav ua tiav - zoo ib yam li Tesla's 4680 hlwb.

BMW tseem tab tom npaj los koom ua ke cov roj teeb rau hauv qhov chaw teeb tsa, uas lub tuam txhab hu ua "pob qhib lub cev". Qhov no kuj zoo li Tesla's "cov qauv roj teeb". Vim tias cov roj teeb roj teeb yog qhov nruj, koj tuaj yeem siv lawv ua ib feem ntawm lub chassis nws tus kheej. Kev them nyiaj sai dua yuav pab txhawb los ntawm BMW hloov mus rau 800V tsav tsheb ciav hlau, zoo li Hyundai's E-GMP. Qhov no yuav tsum ua kom 80% recharges nyob rau hauv 20 feeb nrog 350kW mov.

Txawm hais tias muaj ntau yam ntawm BMW cov lus tshaj tawm ntawm nws txoj kev Sustainability Through Innovation Day tshwm rau echo yam Elon Musk tshaj tawm ntawm Tesla Hnub Roj Teeb 2020, qhov ntawd tsis yog qhov phem. Lawv yog cov kev txhim kho siv tau zoo heev thiab cog lus tias yuav nce mus tom ntej hauv ntau yam, nqi, thiab kev ua haujlwm zoo. Qhov twg BMW tshwj xeeb tshaj yog dhau Tesla, uas tau ua pov thawj nyob rau hauv lwm qhov chaw ntawm Sustainability Through Innovation tshwm sim, yog tsom rau ib puag ncig thiab ncig. Tag nrho cov chaw tsim tsheb yuav siv cov khoom siv rov ua dua tshiab, los ntawm cov rooj zaum mus rau lub log.

BMW tseem tab tom yuav tsim tsheb ICE rau ntau xyoo, tab sis nws lub hom phiaj ntawm kev ua lub luag haujlwm tseem ceeb hauv hluav taws xob yog qhov tseeb. Hauv UK, nws twb yog EV hom khoom muag zoo tshaj plaws nyob rau lub Yim Hli 2022, ntaus Tesla. Lub tuam txhab xav kom muaj ntau tshaj li ob lab BEVs ntawm txoj kev thaum kawg ntawm 2025 thiab cia siab tias ib nrab ntawm nws qhov kev muag khoom thoob ntiaj teb yuav yog BEVs los ntawm 2030. Nws zoo li BMW tau poob nws txoj kev nrog EVs tom qab pib muaj zog pib nrog i3. Tab sis yog tias lub tuam txhab xa tawm ntawm cov lus cog tseg ntawm nws lub platform Gen6, nws tuaj yeem yog ib tus neeg tseem ceeb hauv kev lag luam khoom kim heev BEV, vim nws tau nyob hauv ICE kev lag luam rau ntau xyoo lawm.
