Txawm hais tias koj tab tom txiav txim siab yuav EV, tos xa khoom, lossis tsav tsheb EV, paub yuav ua li cas (thiab li cas) lawv them yog ib feem tseem ceeb ntawm kev ua tswv cuab.
Hauv phau ntawv qhia no, kuv yuav tham txog lub zog (kW) thiab lub zog (kWh).Kev paub qhov txawv yog qhov tseem ceeb!Cov neeg sib xyaw ua ke txhua lub sijhawm - txawm tias cov kws hluav taws xob uas yuav tsum paub zoo dua.
Lub tsheb roj av ib txwm tau txais 10 km ntawm thaj tsam ntawm 1 liter ntawm roj.Ib lub tsheb hluav taws xob raug kwv yees li 6 mais ntawm thaj tsam ntawm 1 kWh ntawm hluav taws xob.
Rau ib lub tsheb petrol, koj xav tau 10 litres roj mus rau 100 km.Tsawg tus nqi ntawm $1.40 ib liter roj, 10 x $1.40 = $14 rau 100 kilometers.
Lus Cim: Cov roj av ntau dua $ 2 ib liter thaum lub sijhawm sau ntawv - tab sis kuv yuav lo nrog $ 1.40 los qhia tias EVs pheej yig dua, txawm tias tus thawj tswj hwm Lavxias tsis tshaj tawm tus nqi roj.
Nyob rau hauv ib lub tsheb hluav taws xob, kwv yees li 16 kWh ntawm hluav taws xob yuav tsum tau mus txog 100 mais.Yog tias koj lub khw muag hluav taws xob them 21 xees ib kWh, tus nqi yog 16 x $ 0.21 = $ 3.36.
Cov tsheb hluav taws xob tsis tshua muaj nqi rau kev tsav tsheb yog tias koj xav txog kev them nyiaj los ntawm lub hnub ci vaj huam sib luag lossis them tus nqi qis tshaj plaws raws li lub sijhawm siv (ToU) tariffs. Cia peb khiav qee tus lej los piav qhia:
Yog tias koj muaj daim nqi hluav taws xob ntawm 21c thiab hnub ci pub-hauv tariff ntawm 8c, tus nqi them lub tsheb nrog lub hnub ci zog yog 8c.Qhov ntawd yog 13c pheej yig dua ib kWh tshaj li them lub tsheb hluav taws xob los ntawm daim phiaj.
Sijhawm-ntawm-siv tariffs them koj cov nqi sib txawv rau hluav taws xob raws li lub sijhawm ntawm hnub koj tau txais los ntawm kab sib chaws.
Sib piv Aurora Energy Tasmania tus nqi hluav taws xob sib txawv ntawm lub sijhawm sib txawv ntawm hnub:
Yog tias koj teem koj lub EV charger tsuas yog khiav ntawm qhov kev pab cuam ToU no nrog Aurora ntawm 10 teev sawv ntxov txog 4 teev tsaus ntuj, 100km ntawm ntau yam yuav raug nqi rau koj 16 x $0.15 = $2.40.
Lub neej yav tom ntej ntawm Australia txoj kev npaj hluav taws xob yog lub sij hawm ntawm kev siv tariffs, qhov pheej yig tshaj hluav taws xob thaum nruab hnub (ntau hnub ci) thiab hmo ntuj (feem ntau muaj cua txaus thiab xav tau me ntsis).
Hauv South Australia, koj raug them tus nqi measly 7.5 xees ib kilowatt-teev ntawm ib hnub thaum lub sij hawm siv cov nqi se uas muaj "hnub ci daim txhuam cev."
Qee cov khw muag khoom kuj tseem muab cov nqi EV tshwj xeeb uas koj tuaj yeem them tus nqi qis dua ib-kWh kom them koj EV nyob rau qee lub sijhawm, lossis tus nqi pheej yig txhua hnub rau kev them nyiaj tsis txwv.
Ib qho kawg - saib xyuas "xav tau tus nqi se".Cov phiaj xwm hluav taws xob no them koj tus nqi hluav taws xob qis dua, tab sis tuaj yeem ua rau koj muaj teeb meem loj yog tias koj siv hluav taws xob ntau tshaj qhov pib.Charging koj EV nrog 3-theem 22 kW charger tuaj yeem txhais tau tias koj them 10x koj tus qauv nqi hluav taws xob!
Ib qho yooj yim EV charger yog ib yam khoom siv yooj yim heev.Nws txoj haujlwm tsuas yog "nug" lub tsheb yog tias nws tuaj yeem lees txais ib qho nqi, thiab yog tias muaj, muab lub zog ruaj ntseg rau lub tsheb kom txog thaum nws hais kom nres.
Lub EV charger tsis tuaj yeem siv lub tsheb nrawm dua li lub tsheb thov rau nws (uas yog qhov txaus ntshai), tab sis yog tias koj muaj qee qhov kev txawj ntse, nws tuaj yeem txiav txim siab kom txo tus nqi qis lossis raws li lwm yam kev mob - piv txwv li:
Lub tsev EV chargers kuj yog AC.Qhov ntawd txhais tau tias lawv tsis ua dab tsi tshwj xeeb.Lawv tsuas yog tswj cov kilowatts ntawm 230V AC mus rau hauv lub tsheb.
Qhov tseeb, lub thawv hluav taws xob uas koj tuaj yeem yuav kom them koj lub tsheb tsis yog technically lub charger.Vim tias txhua yam nws ua yog muab AC lub zog tswj.Technically, lub charger tiag tiag nyob hauv lub tsheb, hloov AC rau DC thiab saib xyuas txhua yam. them cov dej num.
Lub onboard EV charger no muaj zog zog txwv rau nws AC-DC conversion.11 kilowatts yog qhov txwv rau ntau lub tsheb fais fab - xws li Tesla Model 3 thiab Mini Cooper SE.
Nerd lees txim: Kuv yuav tsum technically hu lub cuab yeej koj ntsaws rau hauv koj lub tsheb EVSE (Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob).Tab sis qhov ntawd yuav ua rau cov neeg tsis txaus siab feem ntau, yog li muaj kev pheej hmoo tau txais email npau taws los ntawm tus kws ua haujlwm so haujlwm, kuv hu cov khoom siv no "chargers ”
Dedicated high-speed pej xeem EV chargers yog lawv tus kheej chargers uas pub DC hwj chim ncaj qha mus rau hauv lub roj teeb.Lawv tsis txwv los ntawm lub tsheb charger vim lawv tsis siv.
Yog tias koj lub tsheb tuaj yeem tswj tau nws, cov tub ceev xwm no tuaj yeem them txog li 350 kW ntawm DC.Nco ntsoov tias lawv yuav tsum tau qeeb qeeb thaum koj lub roj teeb nce mus txog 70%. Tseem, lawv tuaj yeem ntxiv 350 mais ntawm ntau yam hauv 10 feeb xwb. .
Kev lag luam tau txais cov ntsiab lus los piav qhia txog kev them nqi qeeb, nruab nrab thiab ceev ceev.Tsuas yog qhov tho txawv, nws hu ua Theem 1, Theem 2, thiab Theem 3 them.
Theem 1 charger tsuas yog ib qho cable thiab lub zog cib uas txuas mus rau tus qauv hluav taws xob taw tes.Lawv them ntawm 1.8 txog 2.4 kW los ntawm lub qhov hluav taws xob hauv tsev.
Pro cov lus qhia: Yog tias koj lub tuam txhab tsheb tsis muab lub xov tooj sib txuas rau koj lub tsheb, xyuas kom koj yuav ib qho thiab khaws cia rau hauv lub cev - nws tuaj yeem txuag koj ib hnub ntawm nqaij npuas kib txawm tias koj tsis siv nws hauv tsev.
Txhawm rau piav qhia qhov theem 1 tus nqi ntawm 1.8 kW txhais tau li cas - nws yuav ntxiv 1.8 kWh ib teev rau koj lub tsheb roj teeb.
1 kWh ntawm lub hwj chim nyob rau hauv ib lub roj teeb EV yog sib npaug li 6 km ntawm ntau yam.Yog li ntawd, theem 1 charger tuaj yeem muab ntau yam li 10 km ib teev.Yog tias koj them lub tsheb hmo ntuj (kwv yees li 8 teev), koj yuav ntxiv txog 80km ntawm qhov chaw.
Tab sis qib 1 tuaj yeem them tus nqi siab dua.Raws li cov chaw tsim khoom, koj lub cuab yeej yuav muaj cov plugs sib hloov.
Txhua lub EV chargers tuaj nrog 10A plugs li niaj zaus, tib yam li tag nrho lwm yam khoom siv hauv koj lub tsev, tab sis qee qhov kuj tuaj yeem hloov tau 15A plugs.Qhov no muaj qhov dav dav hauv av thiab yuav tsum muaj lub qhov (socket) tshwj xeeb uas tuaj yeem tuav cov xov hlau tuab ntawm 15A.Yog tias koj muaj ib tug caravan, koj nyob nraum tej zaum paub nrog lawv.
Qee lub xov tooj ntawm tes muaj 15A "tail".Cov no yog 10A thiab 15A tus Tsov tus tw kawg uas tuaj nrog Tesla mobile charger hauv Australia.
Yog tias koj lub charger portable yog 15A ntawm qhov kawg thiab koj xav them nyiaj tom tsev, koj yuav xav tau 15A qhov hluav taws xob hauv koj qhov chaw nres tsheb. Cia siab tias yuav them txog $ 500 rau qhov kev teeb tsa no.
Nerd Fact: Yog tias koj lub zog hluav taws xob hauv cheeb tsam siab (yuav tsum yog 230V, tab sis feem ntau 240V +), koj yuav tau txais ntau lub zog vim lub zog = tam sim no x voltage.
Ntxiv nerdy qhov tseeb: Nyob ntawm cov chaw tsim khoom, cov khoom siv txawb feem ntau txwv rau 80% ntawm lawv cov ntsuas tam sim no.Yog li lub 10A charger tsuas yog khiav ntawm 8A, thiab 15A ntaus ntawv tsuas yog khiav ntawm 12A.Combined nrog fluctuations nyob rau hauv daim phiaj voltage, nws txhais tau hais tias kuv tsis tuaj yeem muab qhov tseeb EV them ceev rau lub xov tooj txuas.
Tesla Nerd Qhov Tseeb: Tesla mobile chargers tuaj tom qab lub Kaum Ib Hlis 2021 tuaj yeem them tag nrho 10A lossis 15A, nyob ntawm tus Tsov tus tw siv.
Pro cov lus qhia: Yog tias koj muaj Tesla tsis ntev los no thiab muaj hmoo txaus kom muaj peb theem qhov hluav taws xob hauv qhov chaw nres tsheb, koj tuaj yeem yuav tus thib peb tus Tsov tus tw uas tuaj yeem them nqi ntawm 4.8 txog 7kW (20 txog 32A) siv lub xov tooj sib txuas.
âš¡ï¸ âš¡ï¸ Them Ceev: Kwv yees li ntawm 40 km / h (ib theem) lossis txog li 130 km / h (peb-theem)
Theem 2 kev them nyiaj yuav tsum muaj lub tshuab hluav taws xob rau phab ntsa nrog nws tus kheej xaim xaim rov qab rau koj lub hwj chim sawb.
Theem 2 chargers raug nqi $900 txog $2500 rau kho vajtse thiab li ntawm $500 mus tshaj $1000 rau nruab.Qhov no tus nqi kuj xav tias koj lub hwj chim sawb thiab mains yuav lis lub load ntxiv.Yog hais tias lawv ua tsis tau, upgrading koj cov khoom yuav raug nqi ntau txhiab daus las.
Ib theem 7 kW Theem 2 charger tuaj yeem ntxiv txog 40 km ib teev ntawm ntau yam.Yog tias koj lub tsheb tuaj yeem ua tau, peb theem 22 kW EV charger yuav ntxiv txog 130 kilometers ib teev ntawm ntau yam.
Nerd Fact: Thaum 3-theem, theem-2 chargers tuaj yeem tso tawm mus txog 22 kW, ntau lub tsheb tsis tuaj yeem hloov AC lub zog sai sai.Khoom koj lub tsheb specs kom pom nws qhov siab tshaj plaws AC tus nqi.
Lub charger no yog tag nrho DC thiab muaj qhov tso zis ntawm 50 kW txog 350 kW.Lawv raug nqi tshaj $ 100,000 rau nruab thiab xav tau lub zog loj, yog li koj tsis zoo li yuav muaj ib qho teeb tsa hauv koj lub tsev.
Tesla's Supercharger network yog qhov piv txwv nto moo tshaj plaws ntawm Theem 3 charger.Qhov feem ntau "V2" supercharger muaj qhov tso zis siab tshaj plaws ntawm 120 kW thiab kev caij nkoj ntawm 180 mais hauv 15 feeb.
Tesla lub network ntawm Supercharger chaw nres tsheb muab lawv qhov kev sib tw kom zoo dua lwm cov tuam txhab EV vim lawv qhov chaw nyob ntawm cov kev taug kev nrov, kev ntseeg siab / lub sijhawm ua haujlwm, thiab qhov ntim me me piv rau lwm yam Theem 3 chargers.
Txawm li cas los xij, raws li cov tsheb hluav taws xob tau dhau los ua ntau dua, lwm cov kev sib tw sib tw yuav tsum tshwm sim thoob plaws lub tebchaws thiab txhim kho lawv txoj kev ntseeg siab.
Tesla Nerd Qhov Tseeb: Australia cov liab thiab dawb "V2" Tesla Superchargers yog DC them ceev ceev, feem ntau them ntawm 40-100 kW, nyob ntawm seb muaj pes tsawg lub tsheb siv tib lub sijhawm. tuaj yeem them txog 250 kW.
Cov lus qhia Pro: Saib xyuas kom qeeb AC chargers ntawm txoj kev mus ncig.Qee txoj kev chargers yog qeeb qeeb AC hom uas tsuas yog them los ntawm 3 txog 22 kW.Cov no tuaj yeem nce me ntsis thaum koj nres, tab sis tsis ceev txaus kom yooj yim them rau. kev mus.
Txhua lub tsheb hluav taws xob muag hauv tebchaws Australia txij li Lub Ib Hlis 1, 2020 yog nruab nrog lub AC charging socket hu ua 'Type 2' (lossis qee zaum 'Mennekes').
