Cov teeb meem hauv kev lag luam ntawm cov tsheb fais fab tshiab tseem muaj, thiab DC charging piles tuaj yeem ua tau raws li qhov xav tau kom rov ua kom muaj zog sai. Qhov nrov ntawm cov tsheb fais fab tshiab raug txwv los ntawm cov teeb meem tseem ceeb xws li lub roj teeb lub neej thiab kev ntxhov siab ntawm kev them. Txhawm rau teb rau cov teeb meem saum toj no, cov chaw tsim khoom loj tseem txuas ntxiv tsim cov thev naus laus zis roj teeb thiab teb rau kev ntxhov siab ntawm kev lag luam los ntawm kev teeb tsa cov roj teeb ntxiv. Txawm li cas los xij, vim tias nws nyuaj rau ua tiav cov kev tshawb fawb tseem ceeb hauv kev ua haujlwm ntawm cov roj teeb fais fab hauv lub sijhawm luv luv, nws nyuaj rau ua tiav qhov nce ntxiv ntawm qhov mais ntawm ib qho kev them sai sai. Txawm hais tias kev teeb tsa cov roj teeb ntxiv tuaj yeem daws qhov teeb meem kev ntxhov siab ntawm qee tus neeg siv khoom hauv lub sijhawm luv luv, nws cov teebmeem sab yog kev nce ntxiv ntawm lub sijhawm them. Lub sijhawm them yog cuam tshuam nrog lub peev xwm ntawm roj teeb thiab lub zog them. Lub peev xwm ntawm roj teeb loj dua, qhov ntau dua ntawm kev caij nkoj, thiab lub sijhawm them ntev dua yog qhov xav tau yam tsis tau nce lub zog them. Piv nrog AC piles, DC charging piles tuaj yeem them lub roj teeb sai dua, yog li txo lub sijhawm them, txhim kho kev ua haujlwm ntawm kev them, thiab ua tau raws li qhov xav tau ntawm cov tswv tsheb rau kev rov ua kom muaj zog sai.
Nrog rau qhov sib txawv ntawm DC chaw them ceev hloov AC chaw them qeeb, OBC tau dhau los ua qhov tseem ceeb ntawm cov tuam txhab tsheb. Tam sim no, muaj ob txoj hauv kev los them cov tsheb fais fab: ib qho yog los ntawm qhov chaw nres nkoj "them ceev", uas siv DC pawg los them lub roj teeb fais fab ncaj qha; qhov thib ob yog los ntawm AC chaw them, uas yog qhov chaw nres nkoj "them qeeb", uas xav tau lub tsheb Tom qab OBC sab hauv ua transformer thiab rectification, nws yog tso zis los them lub tsheb fais fab. Txawm li cas los xij, raws li DC pawg them ceev maj mam hloov AC pawg them qeeb, qee lub tuam txhab tsheb maj mam sim tshem tawm AC chaw them. Piv txwv li, NIO ET7 tau tshem tawm AC chaw them, tsuas yog tso ib qho DC chaw them thiab tso tseg OBC ncaj qha. Kev tshem tawm OBC tuaj yeem txo qhov hnyav ntawm lub tsheb thiab txo tus nqi ntawm cov tsheb fais fab. Qhov sib txawv ntawm kev tshem tawm AC chaw them yuav tsis tsuas yog txo qhov hnyav ntawm lub tsheb, tab sis kuj txo cov nqi zais xws li kev sib txuas kuaj tsheb, kev sim voj voog, thiab kev nqis peev tsim qauv, uas tuaj yeem txo tus nqi muag ntawm cov tsheb fais fab. Ntxiv mus, vim tias tus nqi kho ntawm OBC siab dua li ntawm cov chaw them hluav taws xob sab nraud DC, kev tshem tawm OBC yuav txo cov nqi siv tsheb tom qab ntawm cov neeg siv khoom.
Tam sim no muaj ob txoj kev rau kev siv tshuab them ceev ceev uas muaj zog heev: kev them ceev ceev tam sim no siab thiab kev them ceev ceev uas muaj zog heev. Txhawm rau teb rau cov teeb meem xws li kev them tsis zoo thiab kev them qeeb qeeb, kev daws teeb meem tseem ceeb hauv kev lag luam yog kev them ceev ceev DC muaj zog heev. Tam sim no, ob lub tsheb thiab cov pawg tau ua tiav qhov loj, thiab lub zog ntawm hom kev them ceev ceev DC muaj feem ntau yog 60-120KW. Txhawm rau kom luv lub sijhawm them, muaj ob txoj kev loj hlob yav tom ntej. Ib qho yog kev them ceev ceev DC tam sim no siab, thiab lwm qhov yog kev them ceev ceev DC muaj zog heev. Lub hauv paus ntsiab lus yog kom nce lub zog them ntxiv los ntawm kev nce tam sim no lossis nce qhov hluav taws xob.
Qhov nyuaj ntawm cov thev naus laus zis them ceev ceev tam sim no yog nws cov kev xav tau cua sov siab. Tesla yog ib lub tuam txhab sawv cev ntawm cov kev daws teeb meem them ceev ceev DC tam sim no siab. Vim yog cov saw hlau xa khoom hluav taws xob siab tsis paub tab hauv theem thaum ntxov, Tesla tau xaiv los khaws lub platform voltage tsheb tsis hloov pauv thiab siv DC tam sim no siab kom ua tiav kev them ceev. Tesla's V3 supercharger muaj qhov tso zis siab tshaj plaws ntawm ze li ntawm 520A thiab lub zog them siab tshaj plaws ntawm 250kW. Txawm li cas los xij, qhov tsis zoo ntawm cov thev naus laus zis them ceev ceev tam sim no siab yog tias nws tsuas tuaj yeem ua tiav lub zog them siab tshaj plaws hauv qab 10-30% SOC tej yam kev mob. Thaum them ntawm 30-90% SOC, piv nrog Tesla V2 them pawg (qhov tso zis siab tshaj plaws tam sim no 330A, lub zog siab tshaj plaws 150kW), qhov zoo tsis pom tseeb. Tsis tas li ntawd, cov thev naus laus zis tam sim no siab tseem tsis tuaj yeem ua tau raws li qhov xav tau ntawm 4C them. Txhawm rau ua tiav 4C them, tseem yuav tsum tau txais yuav lub tsev hluav taws xob siab. Vim tias cov khoom tsim tawm ntau cua sov thaum lub sijhawm them hluav taws xob siab, vim yog kev txiav txim siab txog kev nyab xeeb ntawm lub roj teeb, nws cov qauv tsim sab hauv thiab thev naus laus zis xav tau kev tso cua sov siab heev, uas kuj yuav ua rau tus nqi nce ntxiv.
