Lub tsheb fais fab: nws ua haujlwm npaum li cas?

Kilowatt thiab motorization

Hauv lub tsheb hluav taws xob, koj yuav tsum txhawj xeeb ntau dua li lub roj teeb xwb. Lub cav thiab. Ntawm no dua, lub zog yog thawj zaug qhia hauv kW.

Kuj tseem muaj kev sib txuas lus ntawm kW thiab qhov qub kev ntsuas hauv horsepower: nws txaus los muab lub zog los ntawm 1,359. ... Piv txwv li, Nissan Leaf SV cav muaj 110 kW lossis 147 horsepower. Ntxiv mus, yog tias horsepower yog tus yam ntxwv cuam tshuam nrog cov tsheb thermal, EV cov tuam txhab tseem ceeb tshaj tawm qhov sib npaug kom tsis txhob poob rau cov neeg siv khoom.

Hluav taws xob tsheb Voltage: cuam tshuam rau koj daim ntawv cog lus hluav taws xob

Yog li, watts thiab kilowatts yog cov khoom siv hluav taws xob ntau tshaj plaws hauv kev lag luam tsheb hluav taws xob. Tab sis nyob rau hauv lub tsheb fais fab, voltage kuj tseem ceeb. Piv txwv li, Tesla Model 3 roj teeb ua haujlwm ntawm 350 V.

AC lossis DC tam sim no?

Cov hluav taws xob peb tau txais los ntawm daim phiaj yog 230 volts AC. Qhov no yog hu ua vim hais tias cov electrons tsis tu ncua hloov kev taw qhia. Nws yooj yim dua rau kev thauj mus los, tab sis yuav tsum tau hloov mus rau tam sim no ncaj qha (DC) kom nws tuaj yeem khaws cia hauv EV roj teeb.

Koj tuaj yeem txuas koj lub tsheb mus rau 230 V. Txawm li cas los xij, lub tsheb siv tam sim no ncaj qha los ua haujlwm. Yog li ntawd, hloov los ntawm AC mus rau DC nyob rau hauv lub tsheb fais, ib tug converter yog siv, lub hwj chim ntawm uas yuav ua tau ntau dua los yog tsawg tseem ceeb. Kev suav nyiaj rau lub zog ntawm lub converter no yog qhov tseem ceeb vim hais tias nyob rau hauv cov ntaub ntawv ntawm kev them nyiaj hauv tsev (piv txwv li nyob rau hauv feem ntau ntawm cov neeg siv) nws tuaj yeem cuam tshuam rau koj cov nqi hluav taws xob.

Tseeb, thaum koj sau npe rau qhov kev tso npe, koj muaj lub zog hluav taws xob, qhia hauv kilovoltamperes (kVA, txawm hais tias nws sib npaug rau kW): feem ntau cov ntsuas hluav taws xob muaj qhov sib txawv ntawm 6 txog 12 kVA, tab sis tuaj yeem ncav cuag 36 kVA. yog tias tsim nyog.

Txawm li cas los xij, peb tau piav qhia qhov no hauv peb tsab xov xwm ntawm kev sib raug zoo ntawm kev siv hluav taws xob thiab hluav taws xob ntsuas hluav taws xob: rov them lub tsheb hluav taws xob ib leeg tuaj yeem haus ib feem tseem ceeb ntawm koj cov npe. Piv txwv li, yog tias koj muaj 9kVA subscription thiab koj lub tsheb raug them ntawm 7,4kW (ntawm

phab ntsa lub thawv

Piv txwv li), koj yuav tsis muaj ntau lub zog tshuav rau lub zog rau lwm yam khoom siv hauv tsev (cua sov, qhov hluav taws xob, thiab lwm yam). Ces koj yuav xav tau ib tug loj subscription.

Ib theem lossis peb theem?

Nrog cov ntaub ntawv no hauv siab, tam sim no koj tuaj yeem xaiv koj tus kheej them lub zog. Tau kawg, qhov muaj zog tshaj qhov nqi, lub tsheb yuav them sai dua.

Rau qee lub zog, peb tuaj yeem xaiv peb theem tam sim no , uas yog li ntawd muaj peb theem (hloov ib qho) thiab tso cai rau ntau lub zog. Qhov tseeb, cov motors ntawm lub tsheb fais fab lawv tus kheej siv peb-theem tam sim no. Qhov tam sim no dhau los ua qhov tsim nyog rau kev them rov qab sai tshaj plaws (11 kW lossis 22 kW), tab sis kuj yog rau meters tshaj 15 kVA.

Tam sim no koj muaj cov ntaub ntawv tshiab los pab koj txiav txim siab them nqi xaiv thiab nkag siab zoo dua nws ua haujlwm li cas. Yog tias tsim nyog, IZI los ntawm EDF tuaj yeem pab koj nruab qhov chaw nres tsheb them nyiaj hauv koj lub tsev.
