Thaum cov tsheb fais fab (EVs) tau nrov thoob ntiaj teb, qhov kev xav tau rau cov chaw them hluav taws xob zoo thiab siv tau ntau yam los ua qhov tseem ceeb heev. Cov chaw them hluav taws xob AC (alternating current) thiab DC (direct current) ua haujlwm sib txawv raws li qhov xav tau hluav taws xob thiab cov xwm txheej siv.Chaw them hluav taws xob AC, feem ntau siv rau cov chaw nyob lossis cov chaw lag luam uas tsis muaj zog, muab qhov them qeeb dua tab sis pheej yig dua thiab yooj yim dua rau kev teeb tsa.Cov chargers no feem ntau muaj zog txij li 3 kW txog 22 kW, tsim nyog rau kev them thaum hmo ntuj lossis lub sijhawm nres tsheb ntev.
Ntawm qhov tod tes,DC chaw them ceev ceevua kom tau raws li qhov xav tau ntawm lub zog siab, muab cov peev xwm them ceev ceev uas tseem ceeb rau cov chaw nres tsheb hauv txoj kev loj, cov chaw them ceev ceev hauv nroog, thiab cov tsheb thauj khoom lag luam. Cov chaw them hluav taws xob DC tuaj yeem muab cov theem fais fab ntawm 50 kW mus rau ntau dua 350 kW, txo lub sijhawm them piv rau cov chaw nres tsheb AC. Qhov kev them ceev ceev no yog qhov tseem ceeb rau kev txo lub sijhawm tsis ua haujlwm rau cov neeg tsav tsheb thiab txhawb kev siv cov tsheb fais fab rau kev mus ncig deb thiab kev siv lag luam.
Cov qauv sib txawv thiab cov kev cai rau AC thiab DC chaw them hluav taws xob yog cuam tshuam los ntawm cov yam xws li tus nqi teeb tsa, kev muaj hluav taws xob, thiab kev yooj yim ntawm tus neeg siv.Cov khoom siv them hluav taws xob ACtau txais txiaj ntsig los ntawm cov nqi tsim kho vaj tse qis dua thiab tuaj yeem koom ua ke rau hauv cov kab ke hluav taws xob uas twb muaj lawm nrog kev hloov kho me ntsis. Lawv zoo tagnrho rau qhov chaw uas cov tsheb nres ntev ntev, uas tso cai rau kev hloov pauv hluav taws xob maj mam dua.
Nyob rau hauv kev sib piv,Cov khoom siv them ceev DCxav tau kev nqis peev ntau dua rau hauv kev tsim kho vaj tse, suav nrog kev sib txuas hluav taws xob muaj peev xwm siab dua thiab cov tshuab cua txias siab heev los tswj cov cua sov uas tsim tawm thaum lub sijhawm them hluav taws xob siab. Txawm hais tias tus nqi siab dua, DC chargers yog qhov tseem ceeb rau kev ua kom ntseeg tau tias EVs tuaj yeem them rov qab sai, ua tau raws li qhov xav tau ntawm cov neeg tsav tsheb uas muaj sijhawm tsawg lossis cov neeg taug kev ntev.
Cov qauv kev cai lij choj kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov chaw them hluav taws xob AC thiab DC. Tsoomfwv thiab cov koom haum kev lag luam tsim cov lus qhia kom ntseeg tau tias muaj kev nyab xeeb, kev sib koom tes, thiab kev ua tau zoo. Piv txwv li, tus qauv Combined Charging System (CCS) txhawb nqa ob qho tib si AC thiab DC them, muab kev ywj pheej thiab kev yooj yim rau cov neeg siv EV. Ib yam li ntawd, tus qauv CHAdeMO tsom mus rau DC them ceev, hais txog kev sib raug zoo nrog ntau hom tsheb.
Xaus lus, qhov xav tau ntau yam rau AC thiab DC chaw them hluav taws xob qhia txog qhov xav tau kev sib npaug ntawm txoj hauv kev los tsim cov khoom siv hluav taws xob EV. Txawm hais tias AC chargers muab cov kev daws teeb meem rau kev xav tau them hluav taws xob txhua hnub, DC chargers ceev yog qhov tseem ceeb rau kev ua kom tau raws li qhov xav tau hluav taws xob siab thiab ua kom taug kev mus deb. Thaum lub khw EV txuas ntxiv loj hlob, lub network them hluav taws xob dav dav thiab hloov pauv tau yuav tseem ceeb los txhawb cov kev xav tau ntau yam ntawm cov neeg siv EV.
