Qhov txawv ntawm Theem 2 thiab Qib 3 EV chargers yog dab tsi?
Jan 30, 2024
Cov tsheb hluav taws xob (EVs) tau dhau los ua neeg nyiam vim cov neeg siv khoom nrhiav kev xaiv kev thauj mus los zoo ib puag ncig. Txawm li cas los xij, ib qho kev txhawj xeeb uas cov neeg yuav khoom muaj peev xwm EV muaj yog qhov tsis muaj kev them nqi hluav taws xob thiab lub sijhawm nws siv sijhawm los them lub tsheb hluav taws xob lub roj teeb.
Txhawm rau pab daws cov teeb meem no, automakers thiab cov tuam txhab them nyiaj tau tsim ntau theem lossis "tiers" ntawm cov khoom siv hluav taws xob tsheb (EVSE) uas tuaj yeem them EVs ntawm qhov sib txawv. Ob hom feem ntau yog Theem 2 thiab DC them ceev, tseem hu ua Theem 3 them. Kev nkag siab txog qhov sib txawv ntawm ob theem no yog qhov tseem ceeb rau ob tus tswv EV thiab cov uas tab tom nrhiav rau nruab qhov chaw them nqi rau pej xeem.
Theem 2 Kev them nyiaj yug
Theem 2 chargers, tseem hu ua 240V chargers, yog hom ntau tshaj plaws hauv tsev thiab pej xeem chargers muaj hnub no. Lawv tuaj yeem rov them lub roj teeb EV hauv 4-8 teev nyob ntawm lub tsheb lub roj teeb muaj peev xwm. Nov yog qee yam tseem ceeb kom paub txog Theem 2 them nyiaj:
Voltage: Theem 2 chargers ua haujlwm ntawm 240 volts ntawm alternating tam sim no (AC) fais fab, uas yog tib qhov hluav taws xob xa los ntawm North American lub tsev tshuab ziab khaub ncaws.
Fais fab tso zis: Feem ntau Theem 2 chargers tso zis hluav taws xob nruab nrab ntawm 7-19 kW, nrog 7-11 kW yog qhov ntau tshaj plaws rau kev teeb tsa hauv tsev thiab pej xeem. Qib siab zog 2 units tuaj yeem them sai dua.
Compatibility: Txhua lub tsheb fais fab tuaj yeem them nyiaj siv cov khoom siv Theem 2, txawm tias lub sijhawm them yuav txawv ntawm cov qauv. Theem 2 yog suav tias yog "slow charge" xaiv.
Kev teeb tsa: Theem 2 chargers yog ib qho yooj yim thiab pheej yig rau nruab, raug nqi ib ncig $1,000-2,500 rau ib chav tsev. Pej xeem Qib 2 cov chaw nres tsheb xav tau kev nqis peev ntau dua tab sis tseem pheej yig dua li DC ceev chargers.
Kev Siv: Qib 2 yog qhov zoo tshaj plaws rau cov chaw uas tib neeg yuav tawm ntawm lawv cov EVs nres rau lub sijhawm ntev, xws li tsev, chaw ua haujlwm thiab chaw nres tsheb pej xeem. Nws tso cai rau kev tso lub roj teeb thaum hmo ntuj lossis thaum lub sijhawm ua haujlwm.
Theem 3 Fast Charging
Theem 3 them, tseem hu ua DC them ceev ceev, muab kev them nqi sai dua rau EVs piv rau Qib 2. Ntawm no yog cov yam ntxwv tseem ceeb:
Voltage: Qib 3 siv tam sim no ncaj qha (DC) hloov pauv tam sim no (AC). DC tuaj yeem them lub roj teeb EV ncaj qha yam tsis tas yuav tsum tau hloov pauv, ua kom them sai dua.
Fais fab tso zis: Theem 3 chargers feem ntau tso zis nruab nrab ntawm 50-350 kW ntawm lub hwj chim, uas yog ho siab tshaj theem 2 units. Lub zog siab dua tso cai rau lub sijhawm them luv luv.
Compatibility: Tsis yog txhua lub EVs tau sib xws nrog Theem 3 ceev them. Cov tsheb yuav tsum muaj cov khoom siv hauv nkoj uas tuaj yeem tau txais DC lub zog. Cov tsheb sib xws tseem tuaj yeem them tus nqi qis dua 2.
Kev teeb tsa: Theem 3 ceev chargers yuav tsum muaj hluav taws xob muaj zog thiab cov khoom siv tshwj xeeb tshaj li qib 2 units. Qhov no ua rau lawv kim dua los yuav thiab nruab, txij li $30,000-150,000 rau ib qhov chaw nres tsheb.
Kev Siv: Qib 3 yog qhov zoo tshaj plaws rau cov chaw nres tsheb pej xeem raws txoj kev loj, chaw lag luam loj, lossis lwm qhov chaw uas cov neeg tsav tsheb yuav tsum tau them sai sai thaum nres luv. Ib qho kev them nqi ceev 3 theem tuaj yeem rov ntxiv 200 mais ntawm thaj tsam hauv 20-30 feeb.
Kev sib piv thiab kev txiav txim siab
Thaum Theem 3 them ceev ceev muab kev ua tiav sai dua rau cov tsav tsheb EV ntawm kev mus, Qib 2 tseem yog qhov kev xaiv zoo tshaj plaws rau ntau qhov kev siv vim yog tus nqi qis dua thiab sib haum nrog txhua EVs. Qib 2 yog qhov txaus txaus rau feem ntau txhua hnub thiab hmo ntuj kev xav tau them nyiaj hauv tsev.
Ob theem ntawm kev them nyiaj yuav ua lub luag haujlwm tseem ceeb hauv kev nthuav dav kev siv tsheb fais fab raws li cov txheej txheem nthuav dav. Theem 3 ceev them nyiaj pub rau cov neeg tsav tsheb kom muaj kev nyab xeeb mus ntev, thaum Theem 2 ua tau raws li qhov xav tau ntawm kev tsav tsheb hauv zos thiab kev mus los. Kev nkag siab txog qhov zoo thiab qhov tsis zoo ntawm txhua tus yuav pab cov lag luam thiab cov neeg siv khoom txiav txim siab qhov kev daws teeb meem zoo tshaj plaws.
Nrog rau cov nqi roj nce ntxiv thiab kev txhawj xeeb loj hlob ntawm emissions thiab kev ywj pheej ntawm lub zog, lub tsheb hluav taws xob tau npaj rau kev loj hlob tseem ceeb hauv xyoo tom ntej. Kev nthuav dav qhov muaj nyob rau theem 2 thiab Theem 3 them nyiaj yuav yog qhov tseem ceeb los txhawb kev siv EV ntau dua.
