QuantumScape muab cov ntaub ntawv tseem ceeb hauv lub xeev. Them 4 C, tiv taus 25 C, 0-> 80%. hauv 15 feeb

QuantumScape, pib tsim cov khoom siv hluav taws xob electrolyte, khav txog qhov tsis muaj ntawm nws cov hlwb. Lawv lub peev xwm ua tau zoo heev: lawv tso cai them nyiaj ntawm 4 ° C, tiv taus mus txog 25 ° C, muab lub zog ntom ntom ntawm 0,3-0,4 kWh / kg thiab nyob ib ncig ntawm 1 kWh / l. JB Straubel, co-founder ntawm Tesla, pom qhov no yog qhov kev tawg.

QuantumScape tau dhau los ua nto moo ob zaug yav dhau los: ib zaug, thaum Volkswagen tau los ua tus tswv lag luam tseem ceeb ntawm lub tuam txhab, thiab lub sijhawm thib ob, thaum JB Straubel, co-founder ntawm Tesla, tau los ua tus tswv cuab ntawm pawg thawj coj. Tam sim no nws tau ua nrov nrov rau peb lub sijhawm: lub tuam txhab tau tshaj tawm cov txiaj ntsig ntawm nws cov kev tshawb fawb. Lawv zoo siab rau ntau qhov laj thawj: lub xov tooj ntawm tes ib txwm pom tau tias ua haujlwm ntawm qhov kub thiab txias (30 degrees Celsius), thiab cov txiaj ntsig tau pom tias rov ua dua.

Lub QuantumScape Ceramic Cage yog lub phaj hloov tau hais txog qhov loj ntawm daim npav ua si. Nyob rau sab xis sab xis, koj tuaj yeem pom tus thawj tswj hwm ntawm lub tuam txhab, Jagdeep Singh (c) QuantumScape.

Peb tham txog dab tsi? QuantumScape hlwb yog lithium hlwb uas siv cov khoom siv electrolyte tsis yog kua electrolyte, tsis muaj ib qho anode. Lawv cov anode muaj lithium ions thaum them nyiaj (Li-hlau). Thaum lub cell raug tso tawm, lithium ions mus rau cathode, lub anode yuav tsum tsis muaj.

Cov duab kos duab ntawm lub hnub ci lithium-ion cell (sab laug) thiab QuantumScape cell. Nyob rau hauv lub classic cell los ntawm sab saum toj, peb muaj ib tug electrode, ib tug graphite / silicon anode, ib tug ntxeem tau membrane, ib tug lithium qhov chaw cathode, thiab ib tug electrode. Tag nrho cov no yog immersed nyob rau hauv ib qho electrolyte uas pab txhawb qhov ntws (c) ntawm QuantumScape ions.

Them ntawm 4 C yam tsis muaj derating

Ib qho tseem ceeb ua ntej yog lub peev xwm los them nqi QuantumScape hlwb mus txog 4 ° C yam tsis tau rhuav tshem lawv. Tsis muaj degradation, txij li cov ceramic electrolyte tso cai rau ntws ntawm lithium ions, tab sis tsis tso cai rau lithium dendrites loj hlob. 4 C txhais tau hais tias nrog lub roj teeb 60 kWh peb yuav ncav cuag lub zog them ntawm 240 kW, nrog 80 kWh twb 320 kW, thiab lwm yam.. Nyob rau tib lub sijhawm, peb yuav them txog 80 feem pua ​​​​hauv 15 feeb, yog li qhov nruab nrab them lub zog yuav tsis qis dua qhov siab tshaj plaws - lawv yuav yog 192 thiab 256 kW, raws li.

Xws li lub hwj chim yuav tig mus rau hauv kev ntxiv ntawm qhov ntau ntawm qhov ceev ntawm +1 200 km / h, i.e. + 20 km / min... Kev nres kaum tsib feeb kom ncab koj cov pob txha thiab chav dej yuav muab rau koj nyob ib ncig ntawm 300 mais lossis tshaj 200 mais ntawm txoj kev loj.

Qhov tseem ceeb ntawm "kev cai" ntawm cov hlwb kuj tseem nthuav. Lub tuam txhab khav theeb qhov ntsuas txog 25 C. Piv txwv tias peb yuav siv "tsuas yog" 20 C, lub tsheb nrog 60 kWh roj teeb tuaj yeem tiv taus 1,2 MW txhaj tshuaj!

Tshaj 800 lub luag haujlwm cycles nrog ~ 10% degradation

Lwm qhov txiaj ntsig zoo ntawm QuantumScape hlwb yog lawv lub voj voog siab. Lawv yooj yim mus txog qhov kwv yees li 800 cycles (ua haujlwm = tag nrho cov nqi thiab tso tawm) ntawm 1 ° C thiab cog lus txawm tias muaj zog dua ntawm lub zog qis - thiab qhov kawg tuaj yeem pom hauv tsheb hluav taws xob.

Tej zaum nws yuav zoo li tias 800 lub voj voog tsis muaj ntau, tab sis yog tias peb muab cov nqi no rau ntawm lub tshuab, peb tau txais cov lej loj. Cia peb hais tias peb muaj QuantumScape hlwb sib sau ua ke rau hauv 60 kWh roj teeb. Lub peev xwm no tso cai rau koj yooj yim tsav ntau dua 300 mais. 800 cycles ntawm kev ua haujlwm yog ib mais ntawm yam tsawg kawg 240 txhiab kilometers (daim duab saum toj no).

Nrog xws li ib mais deb, cov ntsiab lus tseem khaws cia txog 90 feem pua ​​​​ntawm lawv lub peev xwm, yog li lawv tso cai rau koj tsav tsis ntau tshaj 300 mais, tab sis tsuas yog 300 mais tsis tau them rov qab! Yog hais tias cov kab degradation txuas ntxiv, uas peb tseem tsis tau paub txog, ntawm 480 80 mais peb yuav ncav cuag txog XNUMX feem pua ​​​​ntawm lub zog thiab lwm yam.

Peb ntxiv tias hnub no lub teeb liab hloov lossis kho lub roj teeb yog lub peev xwm ntawm kwv yees li 65-70 feem pua ​​​​ntawm cov peev txheej qub.

Tom qab tag nrho, txuas mus rau lub dav hlau?

JB Straubel, Tesla tus co-founder thiab tam sim no yog ib tug tswv cuab ntawm QuantumScape pawg thawj coj saib xyuas, pom lub tuam txhab kev ua tiav raws li kev ua tiav.... Nws hais ntxiv tias tam sim no lub zog hluav taws xob tsis tshua muaj tshwm sim, thiab Tesla tau ntsuas kev nce qib hauv ib tus lej feem pua ​​hauv xyoo tas los no. Kev nthuav qhia los ntawm lwm qhov kev pib ua haujlwm feem ntau tsom rau cov kev xaiv xaiv thiab tshem tawm lwm tus, thaum QuantumScape tau pom ntau qhov kev ntsuas hais txog ob qho tib si durability thiab load thiab endurance.

Hauv nws lub tswv yim, cov ntsiab lus tshiab tuaj yeem tso cai rau kev tsim cov dav hlau hluav taws xob nrog cov kev paub txog peb.

cons

Tsis muaj ib qho ntawm cov duab qhia tau them nqi QuantumScape hlwb. Judging los ntawm cov animation, lawv yog heev o. Qhov sib txawv zoo li tsawg kawg yog 2-3 zaug ntau dua li cov lithium-ion hlwb nrog graphite-based anodes, uas tuaj yeem ua rau muaj kev txwv thaum tsim cov roj teeb muaj peev xwm.

Tsim nyog pom (yuav luag 1,5 teev ntawm cov khoom):
