Qhov txawv ntawm qhov tseem ceeb

Yog tias koj muaj lub tsheb fais fab, sai dua lossis tom qab, koj yuav tsoo qee cov ntaub ntawv hais txog AC vs DC them.Tej zaum koj twb paub txog cov ntawv luv no tab sis tsis muaj qhov qhia tias lawv cuam tshuam li cas rau koj EV.

Kab lus no yuav pab koj nkag siab qhov txawv ntawm DC thiab AC chargers.Tom qab nyeem nws, koj tseem yuav paub tias txoj kev them nyiaj sai dua thiab qhov twg yog qhov zoo dua rau koj lub tsheb.

Cia peb pib!

Qhov sib txawv # 1: Qhov Chaw Hloov Lub Hwj Chim

Muaj ob hom hluav taws xob xa hluav taws xob uas tuaj yeem siv los them cov tsheb hluav taws xob.Lawv hu ua Alternating Current (AC) thiab Direct Current (DC) fais fab.

Lub zog los ntawm daim phiaj hluav taws xob yog ib txwm hloov tam sim no (AC).Txawm li cas los xij, lub tsheb roj teeb hluav taws xob tuaj yeem lees txais tsuas yog Direct Current (DC).Qhov sib txawv tseem ceeb ntawm AC thiab DC charging ho, yog qhovqhov chaw uas lub zog AC hloov dua siab tshiab.Nws tuaj yeem hloov pauv sab nraud lossis sab hauv lub tsheb.

DC chargers feem ntau loj dua vim lub converter nyob rau hauv lub chaw nres tsheb them.Qhov no txhais tau tias nws nrawm dua li AC chargers thaum nws los them lub roj teeb.

Los ntawm qhov sib txawv, yog tias koj siv AC them, cov txheej txheem hloov pauv tsuas yog pib hauv lub tsheb.Cov tsheb hluav taws xob muaj lub tshuab hluav taws xob AC-DC built-in hu ua "onboard charger" uas hloov AC zog rau DC lub zog.Tom qab hloov lub zog, lub tsheb lub roj teeb raug them.

Qhov txawv #2: Them hauv tsev nrog AC Chargers

Raws li txoj cai, koj tuaj yeem nruab DC charger hauv tsev.Txawm li cas los xij, nws tsis ua rau muaj kev nkag siab ntau.

DC chargers yog kim kim tshaj li AC chargers.

Lawv siv ntau qhov chaw thiab xav tau ntau qhov chaw seem rau cov txheej txheem xws li kev ua kom txias.

Yuav tsum muaj kev sib txuas hluav taws xob siab rau daim phiaj hluav taws xob.

Ntxiv rau qhov ntawd, DC them nyiaj tsis pom zoo rau kev siv tas li - peb yuav tham txog qhov no tom qab.Muab tag nrho cov lus tseeb no, koj tuaj yeem xaus tias AC charger yog qhov kev xaiv zoo dua rau kev teeb tsa hauv tsev.DC them cov ntsiab lus feem ntau pom nyob rau hauv txoj kev loj.

Qhov txawv #3: Txawb them nrog AC

Tsuas yog AC chargers tuaj yeem ua tau mobile.Thiab muaj ob lub laj thawj tseem ceeb rau nws:

Ua ntej, DC charger muaj lub zog hloov hluav taws xob hnyav heev.Yog li, nqa nws nrog koj ntawm kev mus ncig yog tsis yooj yim sua.Yog li ntawd, tsuas yog cov qauv nyob ruaj ruaj ntawm xws li chargers muaj nyob.

Qhov thib ob, xws li lub charger xav tau cov khoom siv ntawm 480+ volts.Yog li, txawm tias nws yog mobile, koj tsis zoo li yuav nrhiav tau lub zog tsim nyog hauv ntau qhov chaw.Tsis tas li ntawd, feem ntau ntawm cov pej xeem EV them chaw nres tsheb muab AC them, thaum DC chargers feem ntau nyob hauv txoj kev loj.

Qhov txawv #4: DC Charging yog ceev dua AC Charging

Lwm qhov sib txawv tseem ceeb ntawm AC thiab DC them yog qhov ceev.Raws li koj twb paub lawm, DC charger muaj lub converter hauv nws.Qhov no txhais tau hais tias lub hwj chim tawm ntawm DC charging chaw nres tsheb hla lub tsheb onboard charger thiab mus ncaj nraim rau hauv lub roj teeb.Cov txheej txheem no yog lub sij hawm-txuag vim lub converter nyob rau hauv lub EV charger yog npaum li cas npaum li cas tshaj ib tug nyob rau hauv lub tsheb.Yog li ntawd, kev them nyiaj nrog tam sim no ncaj qha tuaj yeem yog kaum lossis ntau zaus sai dua li them nrog cov khoom siv tam sim no.

Qhov txawv # 5: AC vs DC Fais Fab - Sib txawv Charging Curve

Lwm qhov sib txawv ntawm AC thiab DC them nyiaj yog qhov kev them nyiaj nkhaus.Nyob rau hauv rooj plaub ntawm AC them, lub zog xa mus rau EV tsuas yog ib txoj kab ncaj nraim.Yog vim li cas rau qhov no yog qhov me me ntawm onboard charger thiab, raws li, nws txwv lub zog.

Lub caij no, DC them nyiaj tsim qhov kev them nyiaj tsis zoo, vim tias EV roj teeb pib lees txais lub zog nrawm dua, tab sis maj mam yuav tsum tau tsawg dua thaum nws ncav cuag qhov siab tshaj plaws.

Qhov txawv #6: Kev them nyiaj yug thiab roj teeb noj qab haus huv

Yog tias koj yuav tsum txiav txim siab seb puas yuav siv sijhawm 30 feeb lossis 5 teev them koj lub tsheb, koj qhov kev xaiv yog qhov pom tseeb.Tab sis nws tsis yooj yim li, txawm tias koj tsis quav ntsej txog tus nqi sib txawv ntawm qhov ceev (DC) thiab them nyiaj tsis tu ncua (AC).

Qhov khoom yog, yog tias DC charger tau siv tas li, roj teeb kev ua haujlwm thiab kev ua haujlwm ntev yuav raug cuam tshuam.Thiab qhov no tsis yog ib qho lus dab neeg txaus ntshai hauv ntiaj teb e-mobility, tab sis qhov kev ceeb toom tiag tiag uas qee lub tuam txhab e-tsheb txawm suav nrog hauv lawv phau ntawv.

Feem ntau cov tsheb hluav taws xob tshiab txhawb kev them nyiaj tam sim no ntawm 100 kW lossis ntau dua, tab sis kev them nqi ntawm qhov ceev no tsim kom muaj cua sov ntau dhau thiab ua kom lub zog hu ua ripple effect - AC voltage fluctuates ntau dhau ntawm DC fais fab mov.

Lub tuam txhab telematics piv qhov cuam tshuam ntawm AC thiab DC chargers.Tom qab 48 lub hlis ntawm kev txheeb xyuas qhov xwm txheej ntawm cov roj teeb tsheb hluav taws xob, nws pom tias cov tsheb uas siv ceev ceev ntau tshaj peb zaug hauv ib lub hlis nyob rau hauv lub caij ntuj sov los yog huab cua kub muaj 10% roj teeb degradation ntau dua li cov uas tsis tau siv DC ceev chargers.

Qhov txawv #7: AC Charging yog pheej yig dua DC Charging

Ib qho tseem ceeb sib txawv ntawm AC thiab DC them yog tus nqi - AC chargers yog pheej yig dua los siv dua li DC.Qhov khoom yog tias DC chargers kim dua.Nyob rau hauv tas li ntawd, cov nqi installation thiab kab sib txuas cov nqi rau lawv yog siab dua.

Thaum koj them koj lub tsheb ntawm lub zog hluav taws xob DC, koj tuaj yeem txuag tau ntau lub sijhawm.Yog li nws yog qhov zoo tagnrho rau cov xwm txheej uas koj maj nrawm.Hauv cov xwm txheej zoo li no, nws tsim nyog them tus nqi siab dua rau kev them nqi nrawm dua.Lub caij no, them nrog AC lub zog yog pheej yig dua tab sis siv sijhawm ntev dua.Yog tias koj tuaj yeem them koj EV ze rau lub chaw ua haujlwm thaum ua haujlwm, piv txwv li, tsis tas yuav them nyiaj ntau dua rau kev them nyiaj ceev ceev.

Thaum nws los txog rau tus nqi, kev them nyiaj hauv tsev yog qhov kev xaiv pheej yig tshaj.Yog li kev yuav koj tus kheej qhov chaw them nqi yog ib qho kev daws teeb meem uas yuav haum koj lub hnab nyiaj.

Los xaus, ob hom kev them nyiaj muaj lawv cov txiaj ntsig.AC them nyiaj yeej muaj kev noj qab haus huv rau koj lub tsheb roj teeb, thaum lub DC variant tuaj yeem siv rau cov xwm txheej thaum koj xav tau rov qab koj lub roj teeb tam sim ntawd.Los ntawm peb qhov kev paub dhau los, tsis muaj qhov xav tau tiag tiag rau kev them nyiaj ceev ceev, vim tias feem ntau cov tswv EV them lawv cov roj teeb tsheb thaum hmo ntuj lossis thaum nres ze ntawm qhov chaw ua haujlwm.Ib qho AC wallbox xws li go-e Charger Gemini flex lossis go-e Charger Gemini, tuaj yeem yog qhov kev daws teeb meem zoo heev.Koj tuaj yeem nruab nws hauv tsev lossis hauv koj lub tuam txhab lub tsev, ua kom dawb EV them rau koj cov neeg ua haujlwm.

Ntawm no, koj yuav pom txhua qhov tseem ceeb ntawm AC vs DC them thiab qhov sib txawv ntawm lawv:
