DC Fast Charger yog dab tsi?
DC fast chargers, tseem hu ua Theem 3 chargers, yog lub caj qaum ntawm lub tsheb hluav taws xob ceev (EV) them. Tsis zoo li cov kev daws teeb meem qeeb qeeb, uas xa cov kev hloov pauv tam sim no (AC) thiab tso siab rau lub tsheb lub tshuab hluav taws xob hloov pauv hloov mus rau tam sim no ncaj qha (DC), DC ceev chargers xa high-power DC ncaj qha mus rau EV lub roj teeb. Txoj hauv kev ncaj qha no ua rau lub sijhawm them nyiaj sai dua, ua rau cov chargers zoo tagnrho rau kev mus los ntev lossis kev them nyiaj sai thaum lub sijhawm tsis khoom.
DC fast chargers yog sib xws nrog ntau hom connector, xws li CHAdeMO, CCS (Combined Charging System), thiab Tesla Superchargers. Hom connector nyob ntawm ob lub tsheb sib raug zoo thiab cov qauv hauv cheeb tsam. Piv txwv li, Japanese manufacturers feem ntau siv CHAdeMO, thaum European thiab American automakers nyiam CCS connectors. Tesla, nrog rau nws tus kheej Supercharger system, muab nws tus kheej cov kev daws teeb meem ceev ceev, tab sis tsis ntev los no tau txais CCS2 tus qauv hauv Tebchaws Europe kom ua raws li cov kev them nyiaj ntau dua. Fais fab tso zis rau cov chargers no sib txawv heev, xws li los ntawm 50 kW mus rau ntau tshaj 350 kW. Cov zis hluav taws xob ntau dua tuaj yeem ua rau lub sijhawm them sai dua, txo cov sij hawm them rau ib feeb xwb, tsis yog teev.
Kev Lag Luam Evolving rau DC Fast Charging
DC ceev them toj roob hauv pes yog hloov zuj zus sai, uas tau tsav los ntawm kev txhim kho thev naus laus zis thiab kev loj hlob xav tau los txhawb ntau yam ntawm EVs. Raws li ntau tus neeg tsav tsheb hloov mus rau lub tsheb hluav taws xob, qhov kev thov kom sai dua, cov kev daws teeb meem them nqi tau zoo dua. Qhov no yog thawb cov tuam txhab lag luam thiab cov neeg muab kev pabcuam thev naus laus zis los tsim kho tshiab, nrog lub hom phiaj ntawm kev txo cov sijhawm them nyiaj thaum txhim kho tag nrho cov kev ua haujlwm.
Ib qho kev loj hlob loj hauv qhov chaw no yog qhov nce kev siv cov khoom siv ceev ceev, muaj peev xwm xa 350 kW lossis ntau dua, tso cai rau qee lub EVs tau nce ntau pua mais ntawm ntau yam hauv qab 30 feeb. Nyob rau tib lub sijhawm, cov thev naus laus zis thev naus laus zis tau muab tso rau hauv DC ceev chargers. Cov kev daws teeb meem no siv cov kev sib txuas digital los tswj cov khoom thauj thiab txo qis ntawm cov kab hluav taws xob, tshwj xeeb tshaj yog thaum lub sijhawm xav tau siab tshaj plaws. Los ntawm kev sib npaug ntawm cov khoom siv hluav taws xob nrog cov ntaub ntawv hauv lub sijhawm, cov tshuab no tuaj yeem ua kom zoo thaum twg thiab yuav ua li cas lub tsheb raug them, muab cov kev paub zoo rau cov neeg siv thaum txhawb kev siv hluav taws xob.
Lwm qhov tseem ceeb tshaj plaws yog kev hloov pauv mus rau qhov chaw siv hluav taws xob ntsuab rau DC lub chaw them nyiaj ceev ceev. Raws li lub ntiaj teb txav mus rau lub neej yav tom ntej, kev siv zog tau ua kom ntseeg tau tias cov xov tooj them nyiaj siv lub zog txuas ntxiv dua tshiab xws li hnub ci lossis cua zog. Qhov no tsis yog tsuas yog ua tau raws li qhov xav tau ntawm lub zog loj hlob rau EVs tab sis kuj ua raws li cov hom phiaj ntawm ib puag ncig los ntawm kev txo cov pa roj carbon hneev taw cuam tshuam nrog kev them nqi hluav taws xob.
Key Charging Interfaces
DC them ceev ceev siv ntau hom kev sib txuas, txhua tus tsim los ua kom tau raws li kev nyab xeeb thoob ntiaj teb thiab cov qauv txheej txheem xws li ISO 15118 thiab DIN SPEC 70121. Txawm li cas los xij, cov qauv sib txuas sib txawv raws cheeb tsam, cuam tshuam txog ntau yam kev xav tau thiab kev nyiam siv thev naus laus zis ntawm kev lag luam sib txawv. Hauv qab no yog cov ntsiab lus ntawm cov khoom siv feem ntau siv rau DC them ceev ceev:
-CCS1 & CCS2 (Combined Charging System): CCS tus qauv, uas suav nrog CCS1 thiab CCS2 connectors, yog dav siv thoob plaws Europe thiab North America. CCS muab ob qho tib si AC thiab DC them cov kev xaiv nyob rau hauv ib qho kev sib txuas, tso cai rau cov tsheb thauj mus los ntawm lub zog AC qeeb qeeb lossis ceev DC zog nyob ntawm qhov xwm txheej. Ntau lub tuam txhab tsim tsheb, xws li Volkswagen, BMW, thiab Ford, tau txais CCS, thiab muaj lub zog txuas ntxiv mus ua CCS tus qauv thoob ntiaj teb. CCS2 tshwj xeeb tshaj yog nyob hauv Europe, thaum CCS1 feem ntau siv hauv Asmeskas
- DC GB / T: Siv tshwj xeeb hauv Suav teb, tus qauv GB / T ua raws li GB / T 27930 raws tu qauv. Raws li lub lag luam EV loj tshaj plaws hauv ntiaj teb, Tuam Tshoj tau tsim nws tus kheej cov txheej txheem them nqi kom tau raws li cov kev xav tau hauv zos. DC GB / T connector yog dav siv nyob rau hauv Suav teb them network thiab yog tsim los xa high-power charging rau Suav-tsim EVs.
- CHAdeMO: Keeb kwm hauv Nyij Pooj, CHAdeMO tus qauv paub txog nws txoj kev ntseeg tau thiab muaj zog ua lag luam nkag mus rau hauv cheeb tsam. Nws yog ib qho ntawm cov qauv kev them nqi sai sai thiab tau siv los ntawm cov kws tsim tsheb xws li Nissan thiab Mitsubishi. Txawm hais tias cov qauv tshiab zoo li CCS tau nce hauv av thoob ntiaj teb, CHAdeMO tseem yog qhov kev xaiv nrov hauv Nyij Pooj thiab tseem yog ib feem tseem ceeb ntawm kev them nqi ceev ceev.
-Tesla: Tesla tau ntev lawm nyob rau hauv pem hauv ntej ntawm EV ceev them, ua tsaug rau nws tus tswv Supercharger network, uas muab kev kub ceev them rau Tesla tsheb. Thaum pib, Tesla tsheb xav tau lawv tus kheej cov khoom sib txuas, uas txwv kev sib raug zoo nrog lwm cov tes hauj lwm. Txawm li cas los xij, nrog rau kev tshaj tawm Tesla Model 3 hauv Tebchaws Europe, lub tuam txhab tau txais tus qauv CCS2 los muab kev them nyiaj ntau dua rau nws cov neeg siv khoom. Qhov kev hloov pauv no qhia txog Tesla qhov kev txaus siab loj hlob hauv kev ua kom nws lub tsheb sib haum nrog cov neeg thib peb them cov tes hauj lwm, thaum tseem tuav nws tus kheej Supercharger network rau kev ua tau zoo them nqi.
Lub neej yav tom ntej ntawm DC Fast Charging
Lub neej yav tom ntej ntawm DC them ceev ceev tuav lub peev xwm zoo kawg li vim kev tsim kho tshiab txuas ntxiv mus ua lag luam. Nrog rau kev qhia txog kev ntsuas hluav taws xob ntau dua, txhim kho lub peev xwm ntawm kev them nyiaj ntse, thiab ua kom pom tseeb ntawm lub zog ruaj khov, DC them ceev ceev tau muab tso rau kom ua tau raws li qhov xav tau ntawm kev thauj mus los hauv hluav taws xob. Raws li tsoomfwv thiab kev lag luam nqis peev ntau hauv EV infrastructure, tus naj npawb ntawm cov nqi them ceev yuav tsum nce ntxiv, txo kev ntxhov siab ntxiv thiab ua rau cov tswv cuab EV yooj yim dua li qub.
Nyob rau tib lub sijhawm, kev sib koom tes hauv kev lag luam yuav yog qhov tseem ceeb rau kev sib haum xeeb ntawm cov qauv kev them nqi thiab xyuas kom txhua tus neeg tsav tsheb EV, tsis hais tus qauv tsim los yog qauv, muaj kev nkag tau sai, txhim khu kev qha. Kev koom tes thoob ntiaj teb ntawm cov neeg tsim tsheb, them cov chaw muab kev pabcuam, thiab tsoomfwv yog qhov tseem ceeb rau kev tsim kom muaj kev sib txuas, siv tau yooj yim them nyiaj raws li cov kev xav tau ntawm kev lag luam EV loj hlob sai.
