Kev Tshawb Fawb Txog Lub Caij Nyoog 800V: Yuav Ua Li Cas MIDA's 1000V High-Voltage Chargers Ua Rau Koj Lub Neej Yav Tom Ntej Muaj Peev Xwm Txhim Kho Vaj Tse

Kev Hloov Pauv Paradigm: Los ntawm 400V mus rau 800V thiab Tshaj Plaws

Rau feem ntau ntawm kaum xyoo dhau los, kev lag luam tsheb fais fab (EV) tau ua haujlwm ntawm 400V roj teeb architecture. Qhov no yog qhov pib zoo, sib npaug kev ua tau zoo nrog cov nqi ntawm cov khoom siv hluav taws xob. Txawm li cas los xij, peb tau mus txog qhov txwv ntawm 400V systems. Txhawm rau kom ua tiav "10-feeb them" uas cov neeg siv khoom xav tau, cov tuam txhab tsim tsheb tau hloov mus rau 800V thiab 1000V architectures. Cov hom lag luam zoo li Porsche, Hyundai, Kia, thiab Lucid twb tau tsim cov platforms high-voltage, thiab kev lag luam tsheb thauj khoom lag luam tau ua raws li qhov kev cai. MIDA New Energy's 40kW-80kW phab ntsa-mounted DC chargers tau tsim los ua tus choj rau lub neej yav tom ntej high-voltage no.

1. Lub Physics ntawm Kev Ceev: Vim Li Cas Qhov Hluav Taws Xob Siab Dua Yeej

Yuav kom nkag siab tias vim li cas kev lag luam thiaj li hloov mus rau 800V / 1000V, peb yuav tsum saib cov qauv tseem ceeb rau lub zog:Lub zog (Watts) = Qhov hluav taws xob (Volts) × Tam sim no (Amperes).

1.1 Qhov Teeb Meem Kub I²R

• Qhov Kev Sib Tw:Hauv lub tshuab 400V, kom xa tau 80kW ntawm lub zog, lub charger yuav tsum thawb 200 Amps ntawm tam sim no. Cov cua sov tsim nyob rau hauv tus neeg coj hluav taws xob yog proportional rau lub square ntawm tam sim no (P = I²R). Cov hluav taws xob siab ua rau muaj cua sov ntau, xav tau cov xov hlau tuab, hnyav, thiab txias nrog kua uas kim thiab nyuaj rau cov neeg siv tuav.
• Kev daws teeb meem High-Voltage:Los ntawm kev nce lub zog hluav taws xob mus rau 800V, tib lub zog 80kW tuaj yeem xa nrog tsuas yog 100 Amps ntawm tam sim no. Qhov no ua rau cov xov hlau sib dua, yooj ywm dua, pov tseg hluav taws xob tsawg dua, thiab txo qis kev ntxhov siab thermal ntawm lub tsheb lub roj teeb cell thiab lub charger sab hauv circuitry.
• Kev Ua Haujlwm Zoo ntawm Lub Tshuab:Cov tshuab 800V tuaj yeem ua tiav txog li 30% txo qis hauv kev poob ntawm kev them piv rau 400V cov tshuab ntawm tib theem fais fab.

1.2 MIDA lub qab nthab 1000V: Tshaj 800V

Txawm hais tias "800V" yog lo lus nrov, ntau lub tsheb ua haujlwm ntawm qhov hluav taws xob ntawm 700V thiab 920V. MIDA chargers yog tsim los nrog a1000V tso zis txwv, muab qhov kev nyab xeeb tseem ceeb thiab ua kom muaj kev sib raug zoo txawm tias cov roj teeb tiam tom ntej thawb dhau qhov cim 800V mus rau hauv thaj chaw 900V+.

2. Qhov Zoo ntawm 1000V Wide-Voltage: Ib Lub Charger Rau Txhua Tus

Qhov kev pheej hmoo loj tshaj plaws rau tus neeg nqis peev hauv kev tsim kho vaj tse yog "kev tsis siv lawm." Lub charger uas tau teeb tsa niaj hnub no uas tsuas yog tso tawm tau 500V yuav tsis tuaj yeem them lub tsheb 800V ntawm nws qhov ceev ib txwm muaj, lossis qee zaum, txhua.

2.1 Tus Qauv Them Nqi "Universal"

MIDA's WY series muaj cov zis dav dav heev los ntawm150V txog 1000V.

• Hluav Taws Xob Qis (150V-400V):Zoo meej rau cov tsheb fais fab qub (xws li Nissan Leaf thaum ntxov), tsheb kauj vab hluav taws xob, thiab cov tsheb thauj khoom me me hauv nroog.
• Hluav Taws Xob Siab (400V-1000V):Zoo tagnrho rau cov tsheb sedans khoom kim heev tshiab (Porsche Taycan, Lucid Air, Audi e-tron GT) thiab cov platforms ua haujlwm siab (Hyundai E-GMP, Kia EV6).
• Thaj Chaw Fais Fab Tas Mus Li:Lub MIDA UR100060A module tswj nws cov zis tag nrho 60kW los ntawm 300V txog 1000V. Qhov no txhais tau tias lub tsheb nrog lub roj teeb 400V tau txais 60kW, thiab lub tsheb nrog lub roj teeb 800Vthiabtau txais 60kW. Cov chargers ib txwm feem ntau pom lawv lub zog txo qis ib nrab thaum them cov roj teeb hluav taws xob qis dua.

3. SiC (Silicon Carbide): Lub Cav ntawm Kev Ua Haujlwm Zoo Siab

Kev xa hluav taws xob 1000V los ntawm lub tshuab me me uas ntsia rau ntawm phab ntsa yog qhov kev sib tw hauv kev tsim kho uas cov khoom siv hluav taws xob silicon ib txwm tsis tuaj yeem ua tiav. MIDA tau daws qhov no los ntawm kev sib koom ua keSilicon Carbide (SiC)cov khoom siv semiconductor.

3.1 Kev Siv Dav Dav (WBG) Physics

SiC yog cov khoom siv dav dav, txhais tau tias nws muaj lub zog dielectric tawg ntau dua li silicon.

• Txo Qhov Loj:SiC tso cai rau cov modules fais fab me dua. UR100060 yog 50% me dua li cov module silicon sib npaug.
• Kev Hloov Pauv Zoo:SiC txo qhov kev poob ntawm kev hloov pauv mus txog 80%. Qhov no yog qhov tseem ceeb ntawm cov hluav taws xob siab uas qhov kev poob ntawm kev hloov pauv feem ntau yog qhov ua tau zoo.
• Kev Ua Tau Zoo Tshaj Plaws:Lub charger MIDA uas siv SiC tswj tau qhov ua haujlwm tau zoo >95% txawm tias thaum ua haujlwm ntawm ntug ntawm nws lub hnab ntawv 1000V.

4. Kev Sib Txuas thiab Kev Siv Tau Ntev: NACS, CCS, thiab ISO 15118

Kev tiv thaiv yav tom ntej tsis yog hais txog qhov hluav taws xob xwb; nws yog hais txog kev sib txuas lus.

4.1 Kev Ua Rog Txuas: NACS vs. CCS

Lub sijhawm them nqi hluav taws xob tab tom hloov pauv.

• NACS (Tus Qauv Them Nqi Hauv Tebchaws Meskas Sab Qaum Teb):Tesla tus qauv tam sim no tau raug txais yuav los ntawm Ford, GM, thiab Rivian. MIDA muab cov cables NACS uas tau koom ua ke hauv Hoobkas nrog kev txhawb nqa rau Tesla kev sib txuas lus protocol.
• CCS1 & CCS2:Cov qauv thoob ntiaj teb rau North America thiab Europe. MIDA tus qauv txuas modular tso cai rau cov cables hloov pauv yog tias tus qauv kev ua lag luam hauv zos hloov pauv, tiv thaiv kev nqis peev hauv qab lub txee fais fab.
• Kev Hloov Pauv Dynamic:MIDA tus maub los tuaj yeem ntes tau seb nws puas tham nrog CCS lossis NACS lub tsheb thiab hloov cov txheej txheem tau yam tsis tas siv neeg.

4.2 ISO 15118-20: Plug & Charge thiab Ntau Ntxiv

MIDA cov khoom siv kho vajtse tau npaj txhij rau qhov tshiab tshaj plawsISO 15118-20tus qauv.

• Ntsaws & Them:Tsis muaj daim npav RFID ntxiv lawm. Lub tsheb txheeb xyuas nws tus kheej rau lub charger, ua haujlwm kev sib tuav tes ruaj ntseg, thiab them tus nqi ntawm tus tswv tus account tau.
• Kev Ruaj Ntseg Siab Tshaj Plaws:ISO 15118-20 siv TLS 1.3 encryption, kom ntseeg tau tias kev sib txuas lus ntawm lub tsheb thiab lub charger (uas suav nrog cov ntaub ntawv them nqi) yog hacker-proof.

5. V2X: Yav Tom Ntej Ob Txoj Kev ntawm Lub Zog Hluav Taws Xob Siab

Lub caij nyoog 800V kuj tseem yuav yog lub caij nyoog ntawm "Mobile Battery." Cov tsheb yuav tsis tsuas yog siv lub zog xwb; lawv yuav muab nws rov qab.

5.1 Kev Nqus Hluav Taws Xob Ob Txoj Kev

Nrog cov modules fais fab ob txoj kev xaiv tau, MIDA cov chav teeb tsa phab ntsa tuaj yeem txhawb nqa:

• V2G (Tsheb-rau-Grid):Pab cov tuam txhab fais fab kom sib npaug ntawm lub network thaum lub sijhawm muaj neeg coob coob los ntawm kev rub lub zog los ntawm cov EVs uas nres.
• V2B/V2H (Tsheb mus rau Tsev/Tsev):Siv lub tsheb thauj khoom hluav taws xob los muab hluav taws xob rau lub tsev ua haujlwm thaum lub sijhawm tsaus ntuj lossis los txo cov nqi hluav taws xob los ntawm kev siv lub zog hnub ci uas khaws cia thaum hmo ntuj.
• Qhov Zoo ntawm High-Voltage hauv V2X:Kev tso tawm lub roj teeb 800V zoo dua li kev tso tawm lub roj teeb 400V, vim tias qhov poob hloov pauv qis dua.

6. Cov Lus Qhia Txog Kev Npaj Rau Cov Neeg Ua Lag Luam Hauv Kev Tsim Kho Vaj Tse

Yog tias koj tab tom npaj ib qho project EV charging hnub no, ua raws li peb txoj cai no los tiv thaiv koj cov peev txheej:

1. Tsis txhob yuav cov khoom siv uas txwv 500V.Nws zoo ib yam li kev yuav lub xov tooj 3G hauv lub ntiaj teb 5G. Hauv 3-5 xyoos, 800V yuav yog tus qauv tseem ceeb.
2. Muab qhov tseem ceeb rau lub zog ceev.Thaum tus nqi vaj tse nce siab, lub peev xwm los teeb tsa lub tshuab hluav taws xob 80kW muaj zog rau ntawm phab ntsa (tsis yog lub txee hauv pem teb) yog qhov zoo dua rau kev sib tw.
3. Xyuas kom meej tias Modularity.Xaiv cov tshuab zoo li MIDA uas cov modules fais fab tuaj yeem hloov kho lossis hloov tau yooj yim. Cov WY series yog tsim los rau lub neej ua haujlwm 15 xyoo nrog cov khoom sib hloov tau.

7. Xaus Lus: Ua tus thawj coj ntawm 800V Revolution

Kev hloov mus rau kev them hluav taws xob EV siab tsis yog ib qho kev hloov pauv; nws yog ib qho kev hloov pauv tseem ceeb hauv lub cev ntawm kev txav mus los. MIDA New Energy's 1000V-muaj peev xwm phab ntsa DC chargers yog qhov kev daws teeb meem zoo rau lub caij nyoog tshiab no. Los ntawm kev sib txuas ua ke muaj peev xwm siab-voltage nrog SiC efficiency thiab modular tsim, MIDA muab cov cuab yeej uas cov lag luam thiab cov neeg tsav tsheb xav tau kev nqis peev nrog kev ntseeg siab. Tsis txhob tsuas yog tsim rau cov tsheb niaj hnub no; tsim rau cov tsheb ntawm kaum xyoo tom ntej. Mus ncig lub caij nyoog 800V nrog MIDA.
