Cov ntsiab lus mob hauv kev ua lag luam ntawm lub zog tshiab tsheb tseem muaj nyob, thiab DC ceev them pawg tuaj yeem ua tau raws li qhov kev thov kom muaj zog ntxiv. Qhov nrov ntawm lub zog tshiab tsheb yog txwv los ntawm cov ntsiab lus mob tseem ceeb xws li roj teeb lub neej thiab them kev ntxhov siab. Hauv kev teb rau cov teeb meem saum toj no, cov tuam txhab lag luam loj tseem tab tom tsim cov cuab yeej siv roj teeb thiab tau teb rau kev lag luam kev ntxhov siab los ntawm kev txhim kho cov roj teeb ntxiv. Txawm li cas los xij, vim tias nws nyuaj rau kev ua tiav cov thev naus laus zis tseem ceeb hauv kev ua haujlwm ntawm cov roj teeb hluav taws xob hauv lub sijhawm luv luv, nws yog qhov nyuaj rau kev ua tiav qhov tseem ceeb hauv kev nce qib ntawm ib qho nqi sai sai. Txawm hais tias kev txhim kho cov roj teeb ntxiv tuaj yeem daws qhov teeb meem kev ntxhov siab ntau ntawm qee cov neeg siv khoom hauv lub sijhawm luv luv, nws cov kev mob tshwm sim yog qhov nce ntawm lub sijhawm them nyiaj. Lub sijhawm them nyiaj muaj feem xyuam nrog lub peev xwm ntawm lub roj teeb thiab lub zog them. Lub roj teeb muaj peev xwm loj dua, qhov siab dua qhov kev caij nkoj, thiab lub sijhawm them lub sijhawm ntev dua yuav tsum tsis txhob nce lub zog them. Piv nrog AC pawg, DC cov khoom siv ceev ceev tuaj yeem them lub roj teeb sai dua, yog li txo lub sijhawm them nyiaj, txhim kho kev them nqi, thiab ua tau raws li cov kev xav tau ntawm cov tswv tsheb kom ceev zog ntxiv.
Nrog rau qhov sib txawv ntawm DC qhov chaw them nqi ceev hloov pauv AC qeeb them chaw nres tsheb, 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 hluav taws xob: ib qho yog los ntawm qhov chaw nres nkoj "ceev ceev", uas siv DC pawg ncaj qha rau cov roj teeb hluav taws xob; lwm qhov yog los ntawm AC charging chaw nres nkoj, uas yog qhov chaw nres nkoj "slow charge", uas yuav tsum tau lub tsheb Tom qab lub OBC sab hauv ua transformer thiab rectification, nws yog tso tawm kom them lub tsheb fais. Txawm li cas los xij, raws li DC ceev them pawg maj mam hloov AC qeeb them pawg, qee lub tuam txhab tsheb tau maj mam sim tshem tawm AC charging chaw nres nkoj. Piv txwv li, NIO ET7 tau tso tseg qhov chaw nres nkoj AC them, tsuas yog ib qho DC them chaw nres nkoj thiab ncaj qha tso tseg OBC. Kev tshem tawm OBC tuaj yeem txo qhov hnyav ntawm lub tsheb thiab txo tus nqi ntawm lub tsheb fais fab. Cov qauv ntawm kev tshem tawm AC them cov chaw nres nkoj yuav tsis tsuas yog txo lub tsheb hnyav xwb, tab sis kuj txo cov nqi zais xws li kev sib txuas ntawm lub tsheb, kev ntsuas lub voj voog, thiab kev tsim qauv kev nqis peev, uas tuaj yeem txo tus nqi muag tsheb hluav taws xob ntxiv. Tsis tas li ntawd, txij li tus nqi txij nkawm ntawm OBC yog qhov siab dua li ntawm cov khoom siv hluav taws xob sab nraud DC, tshem tawm OBC yuav txo tau cov neeg siv khoom cov nqi siv tsheb tom ntej.
Tam sim no muaj ob txoj hauv kev rau high-power fast charging technology: high-tam sim no them ceev thiab high-voltage fast charging. Nyob rau hauv teb rau cov teeb meem xws li imperfect charging infrastructure thiab qeeb them ceev, lub ntsiab kev daws teeb meem nyob rau hauv kev lag luam yog high-power DC ceev them. Tam sim no, ob lub tsheb thiab pawg tau ua tiav qhov loj, thiab lub zog ntawm cov khoom siv hluav taws xob muaj DC ceev them yog feem ntau 60-120KW. Txhawm rau txo lub sijhawm them nyiaj ntxiv, muaj ob txoj kev txhim kho yav tom ntej. Ib qho yog high-tam sim no DC them ceev, thiab lwm qhov yog High voltage DC ceev them. Lub hauv paus ntsiab lus yog ua kom lub zog them ntxiv los ntawm kev nce tam sim no lossis nce qhov voltage.
Qhov nyuaj ntawm high-tam sim no fast charging technology nyob rau hauv nws cov high heat dissipation yuav tsum tau. Tesla yog ib lub tuam txhab sawv cev ntawm cov kev daws teeb meem DC ceev ceev tam sim no. Vim tias qhov tsis paub txog cov khoom siv hluav taws xob tsis zoo nyob rau theem pib, Tesla tau xaiv los ua kom lub tsheb hluav taws xob tsis hloov pauv thiab siv DC tam sim no kom tau txais kev them nyiaj ceev. Tesla's V3 supercharger muaj qhov tso zis ntau tshaj tam sim no ze li ntawm 520A thiab lub zog them siab tshaj plaws ntawm 250kW. Txawm li cas los xij, qhov tsis zoo ntawm kev them nyiaj ceev ceev tam sim no yog tias nws tsuas tuaj yeem ua tiav lub zog them siab tshaj plaws hauv qab 10-30% SOC cov xwm txheej. Thaum them nyiaj ntawm 30-90% SOC, piv nrog Tesla V2 them pawg (ntau tshaj tawm tam sim no 330A, siab tshaj plaws lub zog 150kW), qhov zoo tsis pom tseeb. Tsis tas li ntawd, cov cuab yeej siv siab tam sim no tseem tsis tuaj yeem ua tau raws li qhov xav tau ntawm 4C them. Txhawm rau kom ua tiav 4C them nyiaj, lub tshuab hluav taws xob siab tseem yuav tsum tau txais yuav. Txij li thaum cov khoom tsim hluav taws xob ntau thaum lub sij hawm them nyiaj tam sim no, 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 yuav tsum muaj cua sov dissipation siab heev, uas yuav ua rau muaj kev nce nqi ntxiv.
