Kev lag luam hluav taws xob tsheb (EV) tau pom kev loj hlob nyob rau xyoo tas los no, vim tias tib neeg thoob plaws ntiaj teb tau paub ntau dua ntawm cov teeb meem ib puag ncig thiab nrhiav kev xaiv kev thauj mus los. Raws li cov qauv no txuas ntxiv zuj zus, kev tsim kho vaj tse los txhawb cov tsheb no yuav tsum tau hloov zuj zus. Lub hauv paus rau txoj kev loj hlob no yog cov chaw nres tsheb hluav taws xob, uas tso cai rau cov neeg tsav tsheb los txhawb lawv lub tsheb. Txawm li cas los xij, tsis yog txhua qhov chaw them nqi yuav zoo ib yam. Qhov tseeb, ib qho ntawm qhov sib txawv tseem ceeb tshaj plaws hauv EV charging yog qhov sib txawv ntawm AC (alternating tam sim no) thiab DC (direct tam sim no) them . Kev nkag siab qhov sib txawv ntawm AC thiab DC EV chargers tuaj yeem pab cov neeg tsav tsheb thiab cov lag luam ib yam li txiav txim siab paub txog lawv cov kev them nqi.
1. AC Charging yog dab tsi?
AC (Alternating Tam sim no) kev them nyiaj yog hom kev them nyiaj ntau tshaj plaws uas siv los ntawm lub tsheb fais fab, tshwj xeeb tshaj yog rau kev them nyiaj hauv tsev thiab Theem 2 them chaw nres tsheb. Hauv AC charging, hluav taws xob ntws hauv ob qho tib si - hloov nws lub polarity los muab lub zog tsim nyog los them lub tsheb lub roj teeb.
AC Charging ua haujlwm li cas?
AC fais fab mov yog muab rau EVs los ntawm tus qauv hluav taws xob qhov hluav taws xob lossis los ntawm cov chaw them nqi AC, feem ntau nyob hauv tsev, cov chaw pej xeem, thiab cov chaw lag luam. Nyob rau hauv cov txheej txheem AC them, lub tsheb nyob rau hauv lub tsheb charger (OBC) ua lub luag haujlwm tseem ceeb hauv kev hloov lub zog AC rau DC lub zog (uas yog hom hluav taws xob xav tau los ntawm lub roj teeb).
Kev them nqi ceev rau AC chargers nyob ntawm lub zog tso zis thiab lub peev xwm ntawm lub charger on-board hauv lub tsheb. Piv txwv li, lub tsev AC chargers muaj nyob nruab nrab ntawm 3.7 kW txog 22 kW them lub zog. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias AC them nyiaj feem ntau qeeb dua li DC them vim tias muaj cov txheej txheem hloov dua siab tshiab uas tshwm sim hauv lub tsheb lub hauv paus system.
Pros ntawm AC Charging
· Muaj dav: AC them chaw nres tsheb muaj ntau, thiab nws yog daim ntawv uas feem ntau siv los them rau lub tsev.
· Nqi-zoo: AC chargers tsis tshua kim rau nruab thiab tswj piv rau DC chargers.
· Kev Txhim Kho Yooj Yim: AC chargers yog yooj yim dua rau nruab, tshwj xeeb tshaj yog nyob rau hauv cov tsev thiab cov tsev nrog cov khoom siv hluav taws xob uas twb muaj lawm.
Cons ntawm AC Charging
· Lub Sijhawm Them Nqi Qis: Vim yog cov txheej txheem hloov dua siab tshiab thiab qis zog tso zis, AC chargers siv sijhawm ntev dua los them tus nqi EV piv rau DC chargers.
· Tsawg Peev Xwm Muaj Peev Xwm: AC chargers raug txwv kom txo qis zog, ua rau lawv tsis haum rau kev them cov roj teeb EV loj sai.
2. DC Charging yog dab tsi?
DC (Direct Current) them , tseem hu ua kev them nyiaj ceev, feem ntau yog siv hauv kev lag luam lossis pej xeem chaw uas xav tau sijhawm them sai dua. Tsis zoo li AC chargers, DC chargers muab hluav taws xob ncaj qha mus rau lub tsheb lub roj teeb nyob rau hauv daim ntawv ntawm DC lub hwj chim, tshem tawm qhov xav tau ntawm on-board charger hloov AC rau DC.
DC Charging ua haujlwm li cas?
Nrog DC them, lub zog xa ncaj qha mus rau lub roj teeb los ntawm lub chaw them nyiaj, hla lub tsheb lub converter sab hauv. Qhov no tso cai rau lub sijhawm them nyiaj sai dua. DC chargers feem ntau yog siv nyob rau hauv high-powered charging chaw nres tsheb thiab yog tsim los kom them EVs sai npaum li cas tshaj lawv AC counterparts.
DC chargers tuaj yeem muab cov qib hluav taws xob nyob qhov twg los ntawm 50 kW mus rau 350 kW lossis ntau dua, uas txo lub sijhawm yuav tsum tau them EV. Piv txwv li, DC charger feem ntau tuaj yeem them tus nqi EV mus rau 80% hauv 30 feeb xwb, thaum lub AC charger yuav siv sij hawm li ob peb teev los ua kom tiav tag nrho, nyob ntawm lub tsheb lub roj teeb muaj peev xwm.
Qhov zoo ntawm DC Charging
· Fast Charging: Qhov txiaj ntsig tseem ceeb ntawm DC charging yog nws qhov ceev. Lub DC charger tuaj yeem them tus nqi EV sai dua li AC charger, txo qis sijhawm thiab ua kom yooj yim rau cov neeg tsav tsheb.
· High Power Output: DC chargers muab lub zog tso zis ntau dua, ua rau lawv zoo tagnrho rau cov lag luam thiab cov neeg tsav nkoj uas xav tau kom them ntau lub tsheb sai sai hauv lub sijhawm luv luv.
Cons ntawm DC Charging
· Cov nqi siab dua: DC chargers kim dua rau nruab thiab tswj, vim lawv cov hluav taws xob ntau dua thiab qhov nyuaj ntawm lawv cov khoom.
· Muaj Tsawg Muaj: Thaum DC chargers nce ntau, lawv tseem tsawg dua li AC chargers. Feem ntau cov chaw nyob yog nruab nrog AC chargers, ua DC chargers feem ntau haum rau pej xeem them chaw nres tsheb lossis kev khiav dej num.

Cov chargers no muaj txiaj ntsig tshwj xeeb rau cov chaw tsheb loj, xws li chaw nres tsheb loj, khw muag khoom, lossis chaw nres tsheb ua lag luam.
Rau Kev Ua Haujlwm Fleet: Rau kev lag luam nkoj nrog ntau tus EVs, DC chargers yog qhov kev xaiv zoo tshaj. Lawv tso cai rau cov thawj coj hauv nkoj kom them nqi tsheb sai thiab ua kom lub sijhawm ua haujlwm siab tshaj plaws ntawm lawv cov haujlwm.
5. Lub neej yav tom ntej ntawm EV Charging Infrastructure
Lub ntiaj teb ntawm EV charging infrastructure yog hloov zuj zus mus sai. Nrog rau kev siv hluav taws xob ntau ntxiv, ob qho tib si AC thiab DC them chaw nres tsheb yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa qhov kev loj hlob no. Raws li cov thev naus laus zis tom qab EVs thiab cov chaw them nqi nce mus, peb tuaj yeem cia siab tias yuav pom kev txhim kho hauv kev them nqi ceev, kev ua tau zoo, thiab kev siv tau yooj yim.
Innovations xws li ultra-ceev DC chargers muaj peev xwm xa mus txog 500 kW ntawm lub hwj chim thiab wireless charging systems twb nyob rau lub qab ntug. Raws li EV kev lag luam loj hlob tuaj, cov kab ntawm AC thiab DC them nyiaj yuav plooj, nrog qee qhov chaw them nqi muab ob qho kev xaiv hauv tib qhov chaw. Tsis tas li ntawd, kev nce qib hauv roj teeb thev naus laus zis tuaj yeem txo lub sijhawm them tag nrho, ua rau AC thiab DC them nyiaj ntau dua.
6. Cov lus xaus
Ob qho tib si AC thiab DC them nyiaj muaj lawv qhov chaw nyob rau hauv kev hloov pauv ntawm cov tsheb hluav taws xob. AC charging yog qhov zoo tagnrho rau kev siv hauv tsev thiab cov xwm txheej uas them thaum hmo ntuj txaus, thaum DC them yog qhov kev daws teeb meem rau cov neeg xav tau them ceev ceev ntawm kev mus. Qhov sib txawv tseem ceeb ntawm AC thiab DC them nyiaj yog nyob ntawm qhov ceev thiab ua haujlwm uas lawv them tus nqi EV, nrog DC muab sijhawm them sai dua ntawm tus nqi siab dua thiab cov zis hluav taws xob.
Raws li kev txais yuav tsheb fais fab txuas ntxiv nce ntxiv, kev nkag siab txog qhov sib txawv no tuaj yeem pab cov neeg tsav tsheb thiab cov lag luam txiav txim siab zoo tshaj plaws rau lawv cov kev xav tau tshwj xeeb.
