Cov tsheb hluav taws xob (EVs) tau dhau los ua neeg nyiam, thiab nrog rau qhov muaj koob npe tuaj qhov xav tau rau kev daws teeb meem zoo. Ib qho tseem ceeb hauv kev txiav txim siab sai npaum li cas EV tuaj yeem raug them yog hom charger siv. Hauv tsab xov xwm no, peb yuav qhia txog qhov sib txawv ntawm DC (Direct Current) thiab AC (Alternating Current) chargers, tsom rau qhov ua rau DC chargers sai dua thiab muaj txiaj ntsig zoo rau EV charging.

Nkag siab txog EV charging technology
Cov tsheb hluav taws xob (EVs) yog siv los ntawm lub tshuab hluav taws xob uas xav tau hluav taws xob khaws cia hauv cov roj teeb. Cov roj teeb no yuav tsum tau them tsis tu ncua, thiab qhov ntawd yog qhov chaw them nyiaj tuaj rau hauv kev ua si. Muaj ob hom kev them nyiaj tseem ceeb: DC (Direct Current) thiab AC (Alternating Current).
AC chargers yog qhov ntau tshaj plaws thiab feem ntau pom muaj nyob hauv cov chaw them nyiaj hauv tsev thiab pej xeem. Lawv hloov pauv tam sim no los ntawm daim phiaj hluav taws xob mus rau tam sim no ncaj qha los them cov roj teeb EV. Ntawm qhov tod tes, DC chargers muab tam sim no ncaj qha mus rau lub roj teeb, hla lub tsheb ntawm lub charger onboard.
Kev them nqi ceev ntawm EV nyob ntawm ntau yam, suav nrog hom charger siv, lub peev xwm ntawm lub roj teeb, thiab lub zog tawm ntawm lub charger. DC chargers paub txog lawv lub peev xwm them ceev, tab sis dab tsi ua kom lawv ceev dua AC chargers?
Qhov zoo ntawm DC chargers tshaj AC chargers
DC chargers muaj ntau qhov zoo dua AC chargers thaum nws los txog rau kev them nqi ceev. Ib qho ntawm cov laj thawj tseem ceeb ntawm DC chargers sai dua yog tias lawv muab cov hluav taws xob ntau dua thiab tam sim no rau lub roj teeb. Qhov no tso cai rau lub roj teeb kom them sai dua, txo lub sijhawm them tag nrho.
Lwm qhov zoo dua ntawm DC chargers yog tias lawv hla lub tsheb lub charger onboard, uas tuaj yeem ua rau lub cev tsis muaj zog hauv cov txheej txheem them nyiaj. Los ntawm muab cov tam sim no ncaj qha rau lub roj teeb, DC chargers tuaj yeem them lub roj teeb ntawm tus nqi nrawm dua, tshwj xeeb tshaj yog thaum siv cov khoom siv hluav taws xob siab.
DC chargers kuj ua tau zoo dua li AC chargers, txhais tau tias tsawg zog yog nkim thaum lub sij hawm them nqi. Qhov no yog vim lub fact tias DC chargers hloov lub hwj chim los ntawm daim phiaj mus rau hauv ncaj qha tam sim no zoo dua AC chargers, uas yuav tsum tau mus rau ib tug ntxiv hloov dua siab tshiab txheej txheem.
Cov yam ntxwv cuam tshuam rau kev them nqi ceev
Thaum hom charger siv yog qhov tseem ceeb hauv kev txiav txim siab them ceev, muaj lwm yam los xav txog ib yam. Ib qho ntawm cov xwm txheej no yog lub peev xwm ntawm EV roj teeb. Lub roj teeb loj dua yuav siv sij hawm ntev dua li lub roj teeb me me, txawm tias siv tib hom charger.
Lub zog tso zis ntawm lub charger yog lwm qhov tseem ceeb. DC chargers tuaj nyob rau hauv ntau theem fais fab, nrog cov qib siab zog muab kev them ceev ceev. Piv txwv li, 150 kW DC charger tuaj yeem them lub roj teeb EV sai dua li 50 kW DC charger.
Ib puag ncig tej yam kev mob kuj tuaj yeem cuam tshuam kev them nqi ceev. Piv txwv li, qhov kub thiab txias tuaj yeem cuam tshuam rau kev ua haujlwm ntawm ob lub charger thiab lub roj teeb, uas tuaj yeem ua rau qeeb ntawm cov txheej txheem them. Tsis tas li ntawd, lub xeev them nqi (SOC) ntawm lub roj teeb - yuav ua li cas puv lossis khoob - tuaj yeem cuam tshuam kev them nqi ceev, nrog rau cov roj teeb them sai dua thaum lawv tsawg dua 50% tag nrho.
Lub neej yav tom ntej ntawm EV charging
Raws li qhov kev thov rau cov tsheb fais fab txuas ntxiv zuj zus, yog li xav tau kev daws teeb meem kom tau txais txiaj ntsig thiab them ceev ceev. DC chargers twb yog ib qho kev xaiv nrov rau kev them nyiaj ceev, tab sis muaj kev txhim kho txuas ntxiv hauv kev them nyiaj thev naus laus zis uas tuaj yeem txhim kho kev them nqi ntxiv.
Ib qho kev loj hlob zoo li no yog kev taw qhia ntawm ultra-ceev DC chargers, uas tuaj yeem muab kev them ceev txog li 350 kW. Cov chargers no tau tsim los them lub roj teeb EV hauv ib feeb ntau dua li cov xuab moos, ua rau lawv zoo tagnrho rau kev mus ncig ntev.
Lwm thaj chaw ntawm txoj kev loj hlob yog wireless charging technology, uas tshem tawm qhov xav tau ntawm lub cev cables thiab connectors. Thaum cov thev naus laus zis no tseem nyob rau theem pib, nws muaj peev xwm hloov pauv EV them los ntawm kev muab kev daws teeb meem yooj yim dua thiab siv tau zoo.
Xaus
Hauv kev xaus, DC chargers sai dua AC chargers vim lawv cov hluav taws xob ntau dua thiab cov zis tam sim no, uas tso cai rau kom them sai dua ntawm EV roj teeb. Lawv kuj hla lub tsheb lub tsheb thauj mus los, txo qhov muaj feem cuam tshuam hauv cov txheej txheem them nyiaj.
Txawm hais tias hom charger yog ib qho tseem ceeb hauv kev txiav txim siab them ceev, lwm yam xws li roj teeb muaj peev xwm, lub charger fais fab tso tawm, thiab ib puag ncig tej yam kev mob kuj ua lub luag haujlwm.
Raws li kev siv thev naus laus zis txuas ntxiv mus, peb tuaj yeem cia siab txawm tias sai dua thiab muaj txiaj ntsig zoo dua cov kev daws teeb meem kom tshwm sim, ntxiv dag zog rau kev rov hais dua ntawm cov tsheb hluav taws xob.
