AC VS DC Charging Chaw nres tsheb

Yog tias koj puas tau xav paub yog vim li cas nws hu ua "DC fast charging," cov lus teb yooj yim. "DC" yog hais txog "ncig tam sim no," hom fais fab uas siv roj teeb. Theem 2 lub chaw them nyiaj siv "AC," lossis "tam sim no hloov," uas koj yuav pom hauv cov khoom siv hauv tsev. EVs muaj onboard chargers nyob rau hauv lub tsheb uas hloov AC zog rau DC rau lub roj teeb. DC fast chargers hloov AC zog rau DC nyob rau hauv lub chaw them nqi thiab xa DC fais fab ncaj qha mus rau lub roj teeb, uas yog vim li cas lawv them sai dua.

Peb cov chaw nres tsheb ChargePoint Express thiab Express Plus muab DC them ceev ceev. Tshawb xyuas peb daim ntawv qhia them nyiaj kom pom qhov chaw them nyiaj ceev nyob ze koj.

DC Fast Charging piav qhia

AC charging yog qhov yooj yim tshaj plaws ntawm kev them nyiaj kom pom - qhov hluav taws xob muaj nyob txhua qhov chaw thiab yuav luag txhua lub EV chargers koj ntsib hauv tsev, khw plazas, thiab chaw ua haujlwm yog Level2 Chargers. Lub AC charger muab lub zog rau lub charger ntawm lub tsheb, hloov lub zog AC mus rau DC thiaj li nkag mus rau lub roj teeb. Qhov kev lees txais ntawm on-board charger txawv ntawm hom tab sis yog txwv rau cov laj thawj ntawm tus nqi, qhov chaw thiab qhov hnyav. Qhov no txhais tau hais tias nyob ntawm koj lub tsheb nws tuaj yeem siv qhov twg los ntawm plaub lossis tsib teev mus rau ntau tshaj kaum ob teev kom them tag nrho ntawm Qib 2.

DC Fast Charging hla dhau tag nrho cov kev txwv ntawm on-board charger thiab yuav tsum tau hloov dua siab tshiab, es tsis txhob muab DC fais fab mov ncaj qha mus rau lub roj teeb, them ceev muaj peev xwm yuav tsum tau ntau zog. Lub sij hawm them nyiaj yog nyob ntawm lub roj teeb loj thiab qhov tso tawm ntawm lub tshuab xa tawm, thiab lwm yam, tab sis ntau lub tsheb muaj peev xwm tau txais 80% nqi nyob rau hauv li lossis qis dua ib teev uas siv tam sim no muaj tam sim no DC chargers.

DC them ceev ceev yog qhov tseem ceeb rau kev tsav tsheb mus deb / ntev thiab cov nkoj loj. Qhov kev hloov pauv sai ua rau cov neeg tsav tsheb tuaj yeem rov qab them nyiaj thaum lawv nruab hnub lossis so me me uas tsis yog raug ntsaws rau hmo ntuj, lossis ntau teev, kom them tag nrho.

Cov tsheb qub muaj cov kev txwv uas tsuas yog tso cai rau lawv them tus nqi ntawm 50kW ntawm DC units (yog tias lawv tuaj yeem ua tau tag nrho) tab sis tam sim no cov tsheb tshiab tau tawm tuaj uas tuaj yeem lees txais txog 270kW. Vim tias cov roj teeb loj tau nce ntxiv txij li thawj EVs ntaus lub lag luam, DC chargers tau txais cov txiaj ntsig siab dua kom phim - nrog qee qhov tam sim no muaj peev xwm txog li 350kW.

Tam sim no, nyob rau hauv North America muaj peb hom DC them ceev: CHAdeMO, Combined Charging System (CCS) thiab Tesla Supercharger.

Txhua lub tuam txhab loj DC charger muaj ntau tus qauv uas muaj peev xwm them tau ntawm CCS lossis CHAdeMO los ntawm tib lub tsev. Tesla Supercharger tsuas tuaj yeem ua haujlwm rau Tesla tsheb xwb, txawm li cas los Tesla tsheb muaj peev xwm siv lwm lub chargers, tshwj xeeb yog CHAdeMO rau DC them ceev ceev, ntawm lub adapter.

 4.DC charging chaw nres tsheb

Lub chaw nres tsheb DC them nyiaj yog thev naus laus zis ntau dua thiab ntau zaus kim dua li AC charging chaw nres tsheb thiab ntxiv rau nws yuav tsum muaj qhov muaj zog. Tsis tas li ntawd, lub chaw nres tsheb DC them nyiaj yuav tsum muaj peev xwm sib txuas lus nrog lub tsheb es tsis txhob siv lub tshuab hluav taws xob nyob rau hauv thiaj li yuav tuaj yeem kho cov zis hluav taws xob tsis zoo raws li qhov xwm txheej thiab lub peev xwm ntawm lub roj teeb.

Feem ntau vim yog tus nqi thiab kev siv thev naus laus zis, peb tuaj yeem suav cov chaw nres tsheb DC tsawg dua li AC chaw nres tsheb. Tam sim no muaj ntau pua ntawm lawv thiab lawv nyob ntawm cov hlab ntsha loj.

Tus qauv fais fab ntawm lub chaw nres tsheb DC yog 50kW, piv txwv li ntau tshaj ob zaug ntawm qhov chaw nres tsheb AC. Ultra-ceev them chaw nres tsheb muaj zog txog li 150 kW, thiab Tesla tau tsim super-ultra-mega-ceev them chaw nres tsheb nrog cov zis ntawm 250 kW.

Txawm li cas los xij, qeeb them nqi siv AC chaw nres tsheb yog maj mam rau cov roj teeb thiab nws pab lawv lub neej ntev, yog li lub tswv yim zoo tshaj plaws yog them los ntawm AC chaw nres tsheb thiab siv DC chaw nres tsheb nkaus xwb ntawm kev mus ntev.

Cov ntsiab lus

Vim tias peb muaj ob hom tam sim no (AC thiab DC), kuj tseem muaj ob lub tswv yim thaum them lub tsheb hluav taws xob.

Nws tuaj yeem siv qhov chaw nres tsheb AC them qhov twg lub charger saib xyuas kev hloov pauv. Qhov kev xaiv no qeeb dua, tab sis pheej yig dua thiab maj mam. AC chargers muaj qhov tso zis ntau txog 22 kW thiab lub sij hawm yuav tsum tau them tag nrho ces nyob ntawm qhov tso zis ntawm on-board charger.

Nws tseem tuaj yeem siv DC chaw nres tsheb, qhov chaw them nqi kim dua, tab sis nws yuav siv sijhawm li ob peb feeb. Feem ntau, lawv cov zis yog 50 kW, tab sis nws xav tias yuav nce ntxiv rau yav tom ntej. Lub hwj chim ntawm ceev ceev yog 150 kW. Ob leeg nyob ib ncig ntawm txoj kev tseem ceeb thiab yuav tsum tau siv rau kev taug kev ntev xwb.

Txhawm rau ua kom qhov xwm txheej nyuaj me ntsis, muaj ntau hom kev them nyiaj sib txuas, cov ntsiab lus uas peb nthuav tawm. Txawm li cas los xij, qhov xwm txheej tau hloov zuj zus thiab cov qauv thoob ntiaj teb thiab cov khoom hloov pauv tau tshwm sim, yog li yav tom ntej, nws yuav tsis muaj teeb meem loj dua li ntau hom kev sib txawv hauv ntiaj teb.
