Vim li cas cov tsheb fais fab mus los ntawm 12 txog 800 volts?

Yuav luag tsis muaj leej twg xav tias hluav taws xob tsheb yuav dhau los ua lub tsheb loj. Thiab ib qho ntawm cov xwm txheej tseem ceeb yuav muaj kev hloov loj ntawm lub tsheb mus rau 800-volt system. Vim li cas qhov no yog qhov tseem ceeb thiab, qhov tseeb, kev zam dhau?

Qhov laj thawj rau kev siv lub siab

Ntau tus neeg tseem tsis nkag siab tias yog vim li cas automakers yuav tsum tau hloov tsheb fais fab los ntawm cov pa hluav taws xob 12-volt mus rau, hais tias, 24 volts, thiab qee qhov ntau dua, mus rau lub platform ntawm ntau pua volts. Qhov tseeb, muaj cov lus piav qhia txog qhov no.

Txhua lub tsheb uas muaj hluav taws xob tiag tiag yog qhov xav tsis thoob uas tsis muaj hluav taws xob siab. Feem ntau cov tsheb fais fab tau nruab nrog cov roj teeb uas muaj qhov ua haujlwm ntawm 400 volts. Cov no suav nrog cov qauv ntawm cov trendsetter hauv hluav taws xob zam - American hom Tesla.

Lub siab ntev dua voltage noj los ntawm lub cev muaj zog, lub zog nws yuav ntau dua. Ua ke nrog ntawm lub hwj chim, kev them tus nqi tseem nce ntxiv. Lub voj voos tsis zoo uas yuam cov tuam ntxhab los tsim kho lub zog tshiab.

Tam sim no, nws tuaj yeem sib cav tias Elon Musk lub tuam txhab yuav tawm sai sai los ntawm Olympus ntawm hluav taws xob tsheb. Thiab yog vim li cas rau qhov no yog kev tsim kho ntawm German engineers. Tab sis txhua yam nyob hauv kev txiav txim.

Vim li cas cov tsheb hluav taws xob tseem tsis tau siv dav siv?

Ua ntej, cia peb teb cov lus nug, dab tsi yog qhov kev khuam siab tseem ceeb rau kev siv hluav taws xob loj heev dua li lawv cov nqi siab? Nws tsis yog tsuas yog kev tsim tsis zoo them cov khoom tsim. Cov neeg siv khoom siv txhawj xeeb txog ob yam: qhov nqi tsheb ntawm lub tsheb hluav taws xob rau ib nqi thiab nws siv sijhawm ntev npaum li cas los them lub roj teeb. Nws yog nyob rau hauv cov ntsuas no uas tus yuam sij rau lub siab ntawm cov neeg siv khoom dag.

Tag nrho lub tshuab hluav taws xob ntawm cov phooj ywg ib puag ncig cov tsheb txuas nrog lub roj teeb uas ua lub cav (ib lossis ntau dua). Nws yog lub roj teeb them uas txiav txim siab qhov tsis yooj yim ntawm lub tsheb. Hluav taws xob hluav taws xob tau ntsuas hauv watts thiab suav los ntawm sib npaug los ntawm voltage los ntawm tam sim no. Txhawm rau txhawm rau kom them tus nqi ntawm cov roj teeb ntawm lub tsheb hluav taws xob, lossis tus nqi nws tuaj yeem nqa, koj yuav tsum nce ntxiv qhov voltage lossis amperage.

Dab tsi yog qhov tsis zoo ntawm qhov siab voltage

Qhov nce ntawm tam sim no yog qhov teeb meem: qhov no ua rau cov kev siv hluav taws xob hnyav thiab hnyav nrog lub rwb thaiv tsev tuab. Ntxiv nrog rau qhov nyhav thiab qhov ntev, cov xaim hluav taws xob ntau tsim muaj ntau qhov kub.

Nws yog ntau qhov kev paub tab rau kev ua haujlwm voltage ntawm lub system. Qhov no qhia dab tsi rau hauv kev coj ua? Los ntawm nce qhov voltage los ntawm 400 mus rau 800 volts, koj tuaj yeem kwv yees ob npaug ntawm lub zog ua haujlwm lossis luv dua roj teeb, lub sijhawm ua tus tswj kev ua haujlwm rau tib lub tsheb. Qee qhov sib npaug tuaj yeem pom ntawm cov yam ntxwv no.

Thawj qhov ntsuas hluav taws xob siab

Thawj lub tuam txhab hloov mus rau 800-volt platform yog Porsche nrog kev tshaj tawm Taycan qauv hluav taws xob. Tam sim no peb tuaj yeem hais nrog kev ntseeg siab tias lwm cov npe hwm yuav sai sai koom nrog German tuam txhab, thiab tom qab ntawd ua qauv ntau. Hloov mus rau 800 volts nce lub zog thaum ua kom nrawm them tib lub sijhawm.

Kev ua haujlwm siab ntau ntawm cov roj teeb Porsche Taycan tso cai rau siv hluav taws xob 350 kW. Lawv twb tau tsim los ntawm Ionity thiab tab tom ua haujlwm nruab thoob plaws hauv Tebchaws Europe. Qhov ua kom yuam kev yog nrog lawv koj tuaj yeem them ib lub roj teeb 800 volt mus rau 80% hauv sijhawm 15-20 feeb xwb. Qhov no txaus kom tsav tsheb txog 200-250 km. Kev txhim kho lub roj teeb yuav ua rau muaj tseeb tias tom qab 5 xyoo kev them lub sijhawm yuav raug txo kom tsis tseem ceeb 10 feeb, raws li kws tshaj lij.

Lub 800-volt architecture xav kom dhau los ua tus qauv rau feem ntau lub tsheb hluav taws xob, tsawg kawg hauv Gran Turismo roj teeb ntu. Lamborghini twb ua hauj lwm rau nws tus kheej qauv, Ford kuj qhia ib tug - Mustang Lithium tau ntau tshaj 900 horsepower thiab 1355 Nm ntawm torque. Kaus lim qab teb Kia tab tom npaj lub tsheb hluav taws xob muaj zog nrog cov qauv zoo sib xws. Lub tuam txhab ntseeg hais tias tus qauv raws li Imagine lub tswv yim yuav muaj peev xwm sib tw nrog Porsche Taycan hais txog kev ua tau zoo. Thiab los ntawm qhov ntawd mus rau pawg pawg ib nrab ib kauj ruam.

Cov Lus Nug thiab Cov Lus Teb:

Lub roj teeb ntawm lub tsheb fais yog dab tsi? Lub roj teeb nruab nrab ntawm lub tsheb hluav taws xob yog 1000-1500 them / tawm mus. Tab sis qhov tseeb dua daim duab nyob ntawm seb hom roj teeb.

Muaj pes tsawg volts nyob rau hauv ib lub tsheb fais? Nyob rau hauv feem ntau cov qauv ntawm niaj hnub hluav taws xob tsheb, kev khiav hauj lwm voltage ntawm ib co ntawm lub on-board network yog 400-450 volts. Yog li ntawd, tus qauv rau lub roj teeb them yog 500V.

Cov roj teeb twg siv hauv tsheb fais fab? Niaj hnub no cov tsheb hluav taws xob feem ntau siv cov roj teeb lithium-ion. Nws tseem ua tau rau nruab ib qho txhuas-ion, lithium-sulfur lossis hlau-air roj teeb.
