Chaw Nres Tsheb AC VS DC

Yog tias koj tau xav paub tias vim li cas nws thiaj hu ua "DC fast charging," cov lus teb yooj yim heev. "DC" txhais tau tias "direct current," hom fais fab uas cov roj teeb siv. Cov chaw them hluav taws xob theem 2 siv "AC," lossis "alternating current," uas koj yuav pom hauv cov qhov hluav taws xob hauv tsev. EVs muaj cov chargers hauv lub tsheb uas hloov AC fais fab mus rau DC rau lub roj teeb. DC fast chargers hloov AC fais fab mus rau DC hauv qhov chaw them hluav taws xob thiab xa DC fais fab ncaj qha mus rau lub roj teeb, yog vim li cas lawv thiaj them sai dua.

Peb cov chaw them fais ChargePoint Express thiab Express Plus muab kev them fais DC sai. Tshawb nrhiav peb daim ntawv qhia chaw them fais kom nrhiav tau qhov chaw them fais ceev ze koj.

Kev Piav Qhia Txog DC Fast Charging

Kev them AC yog hom kev them yooj yim tshaj plaws uas nrhiav tau - cov qhov hluav taws xob muaj nyob txhua qhov chaw thiab yuav luag txhua lub EV chargers uas koj ntsib hauv tsev, khw muag khoom, thiab chaw ua haujlwm yog Level2 Chargers. Lub AC charger muab lub zog rau lub charger hauv lub tsheb, hloov lub zog AC mus rau DC kom nkag mus rau hauv lub roj teeb. Tus nqi lees txais ntawm lub charger hauv lub tsheb txawv ntawm hom tab sis nws txwv vim yog tus nqi, qhov chaw thiab qhov hnyav. Qhov no txhais tau tias nyob ntawm koj lub tsheb nws tuaj yeem siv sijhawm txij li plaub lossis tsib teev mus rau ntau dua kaum ob teev kom them tag nrho ntawm Level 2.

DC Fast Charging hla dhau tag nrho cov kev txwv ntawm lub charger hauv lub tsheb thiab kev hloov pauv uas xav tau, es tsis txhob muab lub zog DC ncaj qha rau lub roj teeb, qhov ceev ntawm kev them hluav taws xob muaj peev xwm nce ntxiv ntau heev. Lub sijhawm them hluav taws xob nyob ntawm qhov loj ntawm lub roj teeb thiab qhov tso zis ntawm lub dispenser, thiab lwm yam, tab sis ntau lub tsheb muaj peev xwm them tau 80% hauv ib teev lossis tsawg dua siv feem ntau cov DC fast chargers tam sim no.

Kev them fais DC sai yog qhov tseem ceeb rau kev tsav tsheb mus deb thiab cov tsheb loj. Qhov kev them fais sai no ua rau cov neeg tsav tsheb tuaj yeem them fais thaum lawv nyob ib hnub lossis thaum so me ntsis es tsis txhob siv hluav taws xob thaum hmo ntuj, lossis ntau teev, kom them fais tag nrho.

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

Tam sim no, hauv North America muaj peb hom DC fast charging: CHAdeMO, Combined Charging System (CCS) thiab Tesla Supercharger.

Txhua lub tuam txhab tsim hluav taws xob DC loj muaj ntau lub tshuab them hluav taws xob uas muaj peev xwm them tau los ntawm CCS lossis CHAdeMO los ntawm tib lub tshuab. Tesla Supercharger tsuas yog siv tau rau Tesla cov tsheb xwb, txawm li cas los xij Tesla cov tsheb muaj peev xwm siv lwm cov tshuab them hluav taws xob, tshwj xeeb yog CHAdeMO rau DC them ceev, los ntawm lub adapter.

 4.DC chaw them nqi

Lub chaw them fais DC nyuaj dua li lwm lub chaw them fais AC thiab kim dua li ntawd, nws yuav tsum muaj lub zog fais DC. Tsis tas li ntawd xwb, lub chaw them fais DC yuav tsum muaj peev xwm sib txuas lus nrog lub tsheb es tsis yog lub charger uas nyob hauv lub tsheb kom thiaj li kho tau qhov tso zis fais raws li qhov xwm txheej thiab lub peev xwm ntawm lub roj teeb.

Vim yog tus nqi thiab kev siv tshuab nyuaj heev, peb suav tau tias muaj tsawg dua DC chaw nres tsheb dua li AC. Tam sim no muaj ntau pua ntawm lawv thiab lawv nyob ntawm cov hlab ntsha loj.

Lub zog txheem ntawm lub chaw them fais DC yog 50kW, uas yog ntau dua ob npaug ntawm lub chaw them fais AC. Cov chaw them fais ceev ultra-fast muaj zog txog li 150 kW, thiab Tesla tau tsim cov chaw them fais super-ultra-mega-fast nrog lub zog tso zis ntawm 250 kW.

Txawm li cas los xij, kev them qeeb qeeb siv cov chaw nres tsheb AC yog qhov mos dua rau cov roj teeb thiab nws pab lawv lub neej ntev, yog li lub tswv yim zoo tshaj plaws yog them ntawm chaw nres tsheb AC thiab siv cov chaw nres tsheb DC tsuas yog thaum mus ncig ntev xwb.

Kev Txheeb Xyuas

Vim tias peb muaj ob hom tam sim no (AC thiab DC), kuj muaj ob txoj hauv kev thaum them lub tsheb fais fab.

Koj siv tau lub chaw them fais AC uas lub charger yuav hloov fais. Qhov kev xaiv no qeeb dua, tab sis pheej yig dua thiab mos dua. Cov charger AC muaj zog txog li 22 kW thiab lub sijhawm uas yuav tsum tau them kom puv nkaus tsuas yog nyob ntawm lub charger uas nyob hauv.

Kuj tseem siv tau cov chaw nres tsheb DC, qhov twg kev them nqi kim dua, tab sis nws yuav tshwm sim hauv ob peb feeb xwb. Feem ntau, lawv cov zis yog 50 kW, tab sis nws xav tias yuav nce ntxiv yav tom ntej. Lub zog ntawm cov chaw them ceev yog 150 kW. Ob qho tib si nyob ib puag ncig cov kev loj thiab yuav tsum siv rau kev mus ncig ntev dua xwb.

Yuav kom qhov teeb meem nyuaj me ntsis, muaj ntau hom kev sib txuas them fais fab, uas peb nthuav qhia txog qhov no. Txawm li cas los xij, qhov teeb meem no tab tom hloov pauv thiab cov qauv thoob ntiaj teb thiab cov adapters tab tom tshwm sim, yog li yav tom ntej, nws yuav tsis yog teeb meem loj dua li ntau hom qhov (sockets) hauv ntiaj teb.
