Voltage: Tus yuam sij zais cia kom qhib tau qhov kev paub zoo dua ntawm EV Charging

Thaum cov neeg tsav tsheb EV tham txog kev them hluav taws xob, "ceev" yeej ib txwm yog lub npe xov xwm. Tab sis qhov tseeb ntawm kev them hluav taws xob sai tsis yog tsuas yog qhov ntsuas hluav taws xob xwb. Qhov hluav taws xob yog qhov kawg txhais qhov txwv siab tshaj plaws ntawm kev ua haujlwm ntawm kev them hluav taws xob, cuam tshuam rau kev noj qab haus huv ntawm lub roj teeb mus sij hawm ntev, thiab txawm tias tsim cov txheej txheem thev naus laus zis yav tom ntej.
Tsab xov xwm no piav qhia txog lub zog fais fab - thiab qhia txog nws cuam tshuam li cas rau txhua qhov kev them nqi uas koj ntsib.

1. Kev Ua Haujlwm Zoo - Vim Li Cas 800V Thiaj Li Los Ua Ib Lub Tuam Txhab Uas Muaj Peev Xwm Loj Hlob

Raws li kev kawm txog lub cev yooj yim, lub zog (P) = qhov hluav taws xob (V) × tam sim no (A).
Yuav kom nce lub zog them, koj tuaj yeem tsa lub zog hluav taws xob lossis thawb ntau dua tam sim no. Tab sis tam sim no siab dua coj cov teeb meem loj: cov xov hlau tuab dua, cua sov ntau dua, thiab kev poob zog ntau dua. Qhov no ua rau kev nce lub zog hluav taws xob yog txoj hauv kev txhim kho zoo dua.

Qhov no yog vim li cas 800V high-voltage platforms feem ntau suav hais tias yog lub sijhawm tseem ceeb rau EV technology.
Xav txog Porsche Taycan—yog ib lub tsheb fais fab 800V uas tsim tawm thawj zaug. Nws lub tshuab txhawb nqa lub zog them hluav taws xob txog li 320 kW. Qhov tseem ceeb tshaj, thaum tib lub zog hloov pauv, tam sim no tuaj yeem txo qis ib nrab, txo qis kev poob cua sov thiab txhim kho kev them hluav taws xob tag nrho.

Qhov tshwm sim yog qhov kev paub zoo dua rau tus neeg siv: Taycan tuaj yeem them tau ntawm 10% txog 80% hauv tsawg li 18 feebntawm lub charger 800V ultra-fast.

2. Kev Sib Txuas Lus - Kev Txawj Ntse thiab Tus Nqi ntawm "Kev Sib Txuas Lus Qis Dua"

Qhov teeb meem niaj hnub no yog tias cov tsheb fais fab uas muaj peev xwm siv tau 800V yeej ib txwm nrhiav tsis tau cov khoom them hluav taws xob siab uas sib phim.
Ib qho piv txwv zoo yog Hyundai IONIQ 5. Txawm hais tias lub tsheb txhawb nqa 800V them, feem ntau Tesla Supercharger V3 chaw nres tsheb xa hluav taws xob li ntawm 500V.
Yuav kom hloov kho tau, lub tsheb yuav tsum qhib nws lub DC/DC converter sab hauv thiab "txo" qhov voltage mus rau 400V—txwv lub zog them siab tshaj plaws kom txog li 135 kW, qis dua nws lub peev xwm siab tshaj plaws ntawm 257 kW.

Qhov kev sib raug zoo no yog kev tsim kho ntse - tab sis nws los nrog kev poob qis ntawm kev ua tau zoo.
Thiab qhov kev txwv no ua rau kev lag luam hloov mus rau qhov chaw them hluav taws xob rau pej xeem uas muaj hluav taws xob ntau dua.

3. Kev Nyab Xeeb Ciam Teb - Cov Kev Txwv Tsis Pub Dhau ntawm Kev Ntsuas Hluav Taws Xob

Thaum cov theem hluav taws xob nce siab, kev nyab xeeb dhau los ua kab liab uas tsis tuaj yeem sib tham tau.
Qhov hluav taws xob siab ua rau muaj kev cai nruj rau kev rwb thaiv tsev, kev tswj hwm thermal, thiab kev saib xyuas lub sijhawm tiag tiag.

IEC 61851 txhais cov kev txwv meej:

• Txog li 1000V AC
• Txog li 1500V DC

Nyob rau tib lub sijhawm, cov qauv kev lees paub CCTA tshiab tam sim no npog 150V–1000V, thiab tab tom tso lub hauv paus rau cov txheej txheem them hluav taws xob megawatt yav tom ntej.

Cov qauv no ua ke tsim cov "kev tiv thaiv" kom ntseeg tau tias kev them sai dua yeej tsis ua rau muaj kev nyab xeeb.

4.Yav Tom Ntej — Dhau Qhov Muaj Hluav Taws Xob Siab Dua, Mus Rau Qhov Muaj Hluav Taws Xob Ntse Dua

Cov theem tom ntej ntawm kev sib tw tsis yog tsuas yog hais txog kev tsa cov platform voltage los ntawm 400V mus rau 800V thiab dhau ntawd.
Tus nqi tiag tiag nyob rau hauv kev tswj hwm hluav taws xob ntse:

• Kev tswj hwm BMS meej
  Kho qhov voltage ramp rates kom zoo thaum lub sijhawm them kawg kom sib npaug qhov ceev thiab lub roj teeb siv tau ntev.
• Kev sib koom tes ntawm lub charger thiab lub tsheb
  Kev sib txuas lus tiag tiag ntawm lub charger thiab lub tsheb BMS los tsim cov kab them nqi zoo tshaj plaws.
• Kev hloov pauv tau rau txhua qhov huab cua
  Cov txheej txheem thermal siab heev ua kom lub zog them ceev tseem muaj kev nyab xeeb thiab ua haujlwm tau zoo thaum txias lossis kub heev.

Xaus lus

Qhov hluav taws xob tsis yog ib qho kev ntsuas kev siv tshuab xwb. Nws txuas nrog kev ua haujlwm ntawm kev them fais, kev sib raug zoo ntawm lub charger, kev nyab xeeb ntawm lub system, thiab kev noj qab haus huv ntawm lub roj teeb.
Rau cov tswv EV, kev nkag siab txog qhov siab tshaj plaws ntawm koj lub tsheb lub zog them yuav pab koj npaj kev mus ncig ntev thiab xaiv cov chargers uas qhib nws qhov kev ua haujlwm tag nrho.
Rau kev lag luam, kev hloov pauv hluav taws xob sawv cev rau kev sib tw dav dav hauv kev tshawb fawb txog cov ntaub ntawv, kev tsim hluav taws xob, thiab kev tswj hwm ntse.

Raws li thev naus laus zis them hluav taws xob hloov zuj zus, cov chargers lawv tus kheej yuav tsum txhawb nqa cov voltage dav dua, lub zog ceev dua, thiab cov algorithms tswj hwm ntse dua.
Qhov no yog qhov tseeb Injet Lub Zog Tshiabtab tom tsim—cov chargers uas qhia ib qho lus yooj yim:
Txawm hais tias thev naus laus zis EV hloov zuj zus li cas los xij, peb xa hluav taws xob sai, muaj kev nyab xeeb, thiab txhim khu kev qha rau txhua lub tsheb.
