Theem 2 EV chargers feem ntau muaj ntau yam kev xaiv fais fab, feem ntau los ntawm 16 amps txog 48 amps. Rau ntau lub tsev thiab lub teeb lag luam teeb tsa hauv xyoo 2025, cov kev xaiv nrov tshaj plaws thiab cov tswv yim yog32 amp, 40 amp, thiab 48 amps. Kev xaiv ntawm lawv yog ib qho kev txiav txim siab tseem ceeb tshaj plaws uas koj yuav ua rau koj qhov teeb tsa EV them.
Tsis muaj ib qho "zoo tshaj" amperage rau txhua tus. Qhov kev xaiv yog nyob ntawm koj lub tsheb tshwj xeeb, koj lub peev xwm hluav taws xob, thiab koj xav tau kev tsav tsheb txhua hnub. Cov lus qhia no yuav muab cov qauv qhia meej, ib kauj ruam los ntawm kauj ruam los pab koj xaiv qhov zoo tshaj plaws amperage, kom ntseeg tau tias koj tau txais qhov kev ua tau zoo uas koj xav tau yam tsis muaj kev siv nyiaj ntau. Rau cov tshiab rau lub ncauj lus, peb phau ntawv qhia rauTheem 2 Charger yog dab tsi?muab cov ntaub ntawv keeb kwm yav dhau zoo heev.
Hom Qib 2 Charger Amps thiab Lub Hwj Chim Tso Tawm (kW)
Ua ntej, cia peb saib cov kev xaiv. ATheem 2 charger lub zog, ntsuas hauv kilowatts (kW), yog txiav txim los ntawm nws cov amperage thiab 240-volt circuit nws khiav. Nws tseem ceeb heev kom nco ntsoov National Electrical Code (NEC) "80% Txoj Cai," uas txhais tau hais tias lub charger txuas ntxiv yuav tsum tsis pub ntau tshaj 80% ntawm nws qhov ntsuas hluav taws xob.
Nov yog yam uas zoo li hauv kev xyaum:
| Charger Amperage | Yuav tsum tau Circuit Breaker | Fais fab tso zis (@240V) | Kwv yees li. Ntau Ntxiv Ntxiv Ib Teev |
| 16 amp ua | 20 amp ua | 3.8 kWm 3 | 12-15 mais (20-24 km) Qhov siab |
| 24 amp ua | 30 amps ib | 5,8 kW :os | 18-22 mais (29-35 km) Qhov siab |
| 32 amp ua | 40 amps ib | 7.7 kWm 0 | 25-30 mais (40-48 km) Qhov siab |
| 40 amps ib | 50 amp ua | 9,6 kW :os | 30-37 mais (48-60 km) Qhov siab |
| 48amp ua | 60 amps ib | 11.5 kW tsi | 37-45 mais (60-72 km) Qhov siab |
Vim li cas Koj Lub Tsheb On-Board Charger Dictates Charging Speed
Qhov no yog qhov tseem ceeb tshaj plaws zais cia hauv EV charging. Koj tuaj yeem yuav qhov muaj zog tshaj plaws 48-amp charger muaj, tab sisnws yuav tsis them koj lub tsheb sai dua li koj lub tsheb On-Board Charger (OBC) tuaj yeem txais.
Kev them nyiaj ceev yog ib txwm txwv los ntawm "kev sib txuas tsis muaj zog" hauv cov saw hlau. Yog tias koj lub tsheb OBC muaj qhov txaus siab tshaj plaws ntawm 7.7 kW, nws tsis muaj teeb meem yog tias lub charger tuaj yeem muab 11.5 kW - koj lub tsheb yuav tsis thov ntau dua 7.7 kW.
Xyuas koj lub tsheb specifications ua ntej koj yuav ib lub charger. Nov yog qee qhov piv txwv nrov:
| Tsheb qauv | Max AC them lub zog | Sib npaug Max Amps |
| Chevrolet Bolt EV (2022+) | 11.5 kW tsi | 48amp ua |
| Ford Mustang Mach-E | 11.5 kW tsi | 48amp ua |
| Tesla Qauv 3 (Standard Range) | 7.7 kWm 0 | 32 amp ua |
| Nissan LEAF (Plus) | 6,6 kW :os | ~ 28 hli |
Yuav 48-amp charger rau Tesla Model 3 Standard Range yog ib qho nyiaj pov tseg. Lub tsheb yuav tsis them sai dua li nws qhov kev txwv 32-amp.
Daim ntawv qhia 3-kauj ruam los xaiv koj qhov zoo meej Theem 2 Charger Amps
Ua raws li cov kauj ruam yooj yim no los ua qhov kev xaiv zoo.
Kauj Ruam 1: Tshawb xyuas koj lub tsheb tus nqi them nyiaj Max
Nov yog koj qhov "speed limit." Saib hauv koj lub tsheb tus tswv phau ntawv los yog tshawb hauv online rau nws cov lus qhia tshwj xeeb ntawm lub charger. Tsis muaj laj thawj los yuav lub charger nrog ntau lub amps dua li koj lub tsheb tuaj yeem ua tau.
Kauj Ruam 2: Ntsuas Koj Lub Vaj Huam Sib Luag Hluav Taws Xob
Theem 2 charger ntxiv cov hluav taws xob loj rau koj lub tsev lossis kev lag luam. Koj yuav tsum sab laj ib tus kws kho hluav taws xob uas muaj ntawv tso cai los ua "kev xam cov load."
Qhov kev ntsuas no yuav txiav txim siab seb koj lub vaj huam sib luag tam sim no puas muaj peev xwm txaus kom muaj kev nyab xeeb ntxiv rau 40-amp, 50-amp, lossis 60-amp Circuit Court. Cov kauj ruam no kuj yog qhov uas koj yuav txiav txim siab txog kev sib txuas ntawm lub cev, feem ntau aSIB 14-50lub qhov hluav taws xob, uas yog heev rau 40-amp chargers.
Kauj Ruam 3: Xav txog koj Cov Kev Tsav Tsheb Txhua Hnub
Ua siab ncaj txog koj tsav tsheb npaum li cas.
• Yog tias koj tsav 30-40 mais ib hnub:Lub 32-amp charger tuaj yeem ua kom tiav qhov ntau ntawm tsawg dua ob teev ib hmos. Nws yog ntau tshaj li txaus rau cov neeg feem coob.
•Yog tias koj muaj ob lub EV, kev mus los ntev, lossis xav tau kev hloov pauv sai dua:Lub 40-amp lossis 48-amp charger yuav zoo dua, tab sis tsuas yog koj lub tsheb thiab hluav taws xob vaj huam sib luag tuaj yeem txhawb nqa nws.
Yuav Ua Li Cas Koj Qhov Kev Xaiv Amperage cuam tshuam rau cov nqi teeb tsa
Xaiv ib qho amperage charger ncaj qha cuam tshuam koj cov peev nyiaj. CovTsev EV Charger Installation Nqitsis yog hais txog lub charger xwb.
Lub 48-amp charger yuav tsum muaj 60-amp Circuit Court. Piv rau 40-amp Circuit Court rau 32-amp charger, qhov no txhais tau tias:
•Thicker, kim dua tooj liab thaiv.
• Ib qho kim dua 60-amp Circuit Court breaker.
• Muaj feem ntau dua ntawm kev xav tau kev hloov kho vaj huam sib luag tseem ceeb yog tias koj lub peev xwm raug txwv.
Ib txwm tau txais cov ncauj lus kom ntxaws los ntawm koj tus kws kho hluav taws xob uas npog cov ntsiab lus no.
Kev Pom Kev Lag Luam: Amps rau Kev Lag Luam & Kev Siv Fleet
Rau cov khoom lag luam, qhov kev txiav txim siab yog qhov muaj tswv yim ntau dua. Thaum them nyiaj sai dua zoo dua, txhim kho ntau lub tshuab hluav taws xob siab tuaj yeem xav tau kev hloov kho hluav taws xob loj, kim kim.
Lub tswv yim ntse dua feem ntau suav nrog kev siv ntau lub chargers ntawm qhov qis dua, zoo li 32A. Thaum ua ke nrog kev tswj xyuas cov khoom siv ntse, ib lub cuab yeej tuaj yeem ua haujlwm rau ntau tus neeg ua haujlwm, cov neeg xauj tsev, lossis cov neeg siv khoom ib txhij yam tsis muaj overloading nws cov hluav taws xob. Qhov no yog qhov sib txawv tseem ceeb thaum xav txogIb Theem vs Peb Theem EV Chargers, raws li peb-theem fais fab, muaj nyob rau hauv cov chaw lag luam, muab kev yooj yim dua rau cov kev teeb tsa no.
Puas Faster Charging txhais tau tias kev tu ntau dua?
Tsis tas li, tab sis durability yog qhov tseem ceeb. Lub charger zoo, tsis hais nws qhov amperage, yuav txhim khu kev qha. Xaiv ib chav tsev zoo tsim los ntawm cov chaw tsim khoom muaj npe nrov yog qhov tseem ceeb rau kev txo qis mus ntevEV Charging Chaw Nres Tsheb Kho Tus Nqithiab xyuas kom koj cov peev nyiaj tau ntev.
Kuv puas tuaj yeem nruab txawm tias Faster Chargers hauv tsev?
Tej zaum koj yuav xav tsis thoob txog cov kev xaiv sai dua. Thaum nws yog technically tau txais ibDC Fast Charger Hauv Tsev, nws yog tsis tshua muaj heev thiab incredibly kim. Nws yuav tsum muaj kev lag luam-qib peb-theem hluav taws xob kev pabcuam thiab tuaj yeem raug nqi ntau txhiab daus las, ua rau Qib 2 tus qauv thoob ntiaj teb rau kev them nyiaj hauv tsev.
Kev Nyab Xeeb Ua Ntej: Vim li cas Kev Txhim Kho Kev Lag Luam yog Tsis-Negotiable
Tom qab koj tau xaiv koj lub charger, tej zaum koj yuav raug ntxias kom nruab nws tus kheej kom txuag tau nyiaj.Qhov no tsis yog qhov project DIY.Theem 2 charger installation yuav tsum ua hauj lwm nrog high-voltage hluav taws xob thiab yuav tsum muaj kev nkag siab tob txog cov lej hluav taws xob.
Txhawm rau kom muaj kev nyab xeeb, ua raws, thiab tiv thaiv koj qhov kev lees paub, koj yuav tsum ntiav ib tus kws tshaj lij hluav taws xob muaj ntawv pov hwm. Tus kws tshaj lij ua kom txoj haujlwm ua tiav, ua rau koj muaj kev thaj yeeb nyab xeeb.
