Kufamba-famba muEra ye800V: Maitiro eMIDA's 1000V High-Voltage Chargers Anoratidza Remangwana Mari Yako Yekudyara muInfrastructure

Kuchinja kweParadigm: Kubva pa400V kusvika ku800V uye Kupfuura

Kwenguva yakareba yemakore gumi apfuura, indasitiri yemotokari dzemagetsi (EV) yave ichishanda pabhatiri re400V. Iyi yaive nzvimbo yekutanga ine musoro, ichienzanisa mashandiro nemitengo yemagetsi emagetsi. Zvisinei, tasvika pamiganhu ye400V systems. Kuti tiwane "chaji yemaminitsi gumi" iyo vatengi vanoda, vagadziri vemotokari vari kukurumidza kutendeukira kune 800V ne1000V architectures. Makambani akaita sePorsche, Hyundai, Kia, naLucid atotanga mapuratifomu ane voltage yakawanda, uye indasitiri yemarori ekutengeserana iri kuteverawo. Machaja eDC eMIDA New Energy ane 40kW-80kW akagadzirwa kuti ave bhiriji rekuenda kune iri ramangwana rine voltage yakawanda.

1. Fizikisi Yekumhanya: Nei Higher Voltage Ichikunda

Kuti tinzwisise kuti sei indasitiri iyi iri kuenda ku800V/1000V, tinofanira kutarisa fomura yekutanga yesimba:Simba (Watts) = Voltage (Volts) × Current (Amperes).

1.1 Dambudziko reI²R Heat

• Dambudziko:Musystem ye400V, kuti ipe simba re80kW, charger inofanira kusunda maAmps mazana maviri emagetsi. Kupisa kunogadzirwa muconductor kunoenderana neskweya yemagetsi (P = I²R). Simba remagetsi rakawanda rinopa kupisa kwakawanda, zvichida tambo dzakakora, dzinorema, dzakatonhodzwa nemvura dzinodhura uye dzakaoma kubata nevashandisi.
• Mhinduro yeHigh-Voltage:Nekuwedzera voltage kusvika ku800V, simba re80kW rimwe chete rinogona kuendeswa ne100 Amps yemagetsi chete. Izvi zvinoita kuti tambo dzakareruka, dzive nyore kushandisa, simba shoma risingashandiswi, uye kuderedza zvakanyanya kushushikana kwekupisa pamabhatiri emotokari uye mukati memagetsi echaja.
• Kushanda Nesimba KweSisitimu:Masisitimu e800V anogona kudzikira kusvika pa30% mukurasikirwa kwekuchaja zvichienzaniswa nemasisitimu e400V ari padanho remagetsi rimwe chete.

1.2 MIDA's 1000V Ceiling: Kupfuura 800V

Kunyange hazvo "800V" iriyo izwi guru, mota zhinji dzinoshanda pamagetsi ari pakati pe700V ne920V. Machaja eMIDA akagadzirwa neMuganho wekubuda kwe1000V, ichipa mukana wakakosha wekuchengetedza uye ichivimbisa kuti inoenderana kunyangwe mabhatiri echizvarwa chinotevera achipfuura chiratidzo che800V achipinda munzvimbo ye900V+.

2. Kubatsira kwe1000V Wide-Voltage: Charger imwe chete kune vese

Njodzi huru kune vanoisa mari muzvivakwa ndeye "kusashanda." Chaja yakaiswa nhasi inongoburitsa 500V chete haigone kuchaja mota ye800V nekumhanya kwayo, kana mune dzimwe nguva, zvachose.

2.1 Kuchaja kwe "Universal"

Nhevedzano yeMIDA yeWY ine huwandu hwakakura hwezvinobuda kubva150V kusvika 1000V.

• Voltage Yakaderera (150V-400V):Yakanakira maEV ekare (senge Nissan Leaf yekare), midhudhudhu yemagetsi, uye maveni madiki ekutakura zvinhu muguta.
• Voltage Yakakwira (400V-1000V):Yakanakira mota dzemhando yepamusoro dzemhando yepamusoro (Porsche Taycan, Lucid Air, Audi e-tron GT) uye mapuratifomu anoshanda zvakanyanya (Hyundai E-GMP, Kia EV6).
• Dunhu reMagetsi Rinogara Richishandiswa:Module yeMIDA UR100060A inochengetedza simba rayo rose re60kW kubva pa300V kusvika ku1000V. Izvi zvinoreva kuti mota ine bhatiri re400V inowana simba re60kW, uye mota ine bhatiri re800Vzvakareinowana simba re60kW. Machaja echinyakare anowanzoona simba rawo richideredzwa nehafu kana richichaja mabhatiri ane voltage shoma.

3. SiC (Silicon Carbide): Injini Inoshanda Nesimba Repamusoro

Kuendesa 1000V kubva kuyuniti diki yakasungirirwa pamadziro idambudziko reinjiniya iro electronics dzechinyakare dzakavakirwa pasilicon dzakatadza kusangana naro. MIDA yakagadzirisa izvi nekubatanidzaSilicon Carbide (SiC)semiconductors.

3.1 Fizikisi yeBandgap Yakafara (WBG)

SiC chinhu chakakura, zvichireva kuti ine simba guru rekupwanya dielectric kupfuura silicon.

• Kuderedza Saizi:SiC inobvumira mamodule emagetsi madiki zvikuru. Iyo UR100060 idiki ne50% pane module yakaenzana nesilicon.
• Kushanda Nesimba Kwekuchinja:SiC inoderedza kurasikirwa kweswitching kusvika ku80%. Izvi zvakakosha pamagetsi akakwira apo kurasikirwa kweswitching kunowanzo tungamira mukushanda zvakanaka.
• Kushanda Kwepamusoro-soro:Chaja yeMIDA ine SiC inoshanda zvakanaka kupfuura 95% kunyangwe ichishanda pamucheto wehamvuropu yayo ye1000V.

4. Kubatana uye Kureba Kweprotocol: NACS, CCS, uye ISO 15118

Kudzivirira ramangwana hakusi kungoshandisa magetsi chete; asi kutaura.

4.1 Hondo dzeConnector: NACS vs. CCS

Mamiriro ekuchaja ari kuchinja.

• NACS (North America Charging Standard):Mutemo waTesla wava kushandiswa neFord, GM, naRivian. MIDA inopa tambo dzeNACS dzakabatanidzwa mufekitori nerutsigiro rwechivanhu rweprotocol yekutaurirana yeTesla.
• CCS1 neCCS2:Zvinodiwa pasi rose zveNorth America neEurope. Dhizaini yeMIDA yekubatanidza mamodular inobvumira kuti tambo idzi dzichinjwe kana mwero wemusika wemuno ukachinja, zvichidzivirira mari inoshandiswa mumagetsi.
• Kuchinja Kunochinja:Chinodzora cheMIDA chinogona kuona kana chiri kutaura nemotokari yeCCS kana NACS uye chochinja otomatiki maprotocol.

4.2 ISO 15118-20: Kuvhara & Kuchaja uye Kupfuura

Hardware yeMIDA yagadzirira zvitsvaISO 15118-20mwero.

• Puragi & Chaja:Hapana makadhi eRFID asara. Mota inozviratidza kune charger, inobata ruoko rwekuchengetedza, uye inobhadharisa account yemuridzi otomatiki.
• Kuchengetedzwa Kwepamusoro:ISO 15118-20 inoshandisa TLS 1.3 encryption, ichiva nechokwadi chekuti kutaurirana pakati pemotokari nechaja (inosanganisira data rekubhadhara) hakupindirwe nema "hackers".

5. V2X: Remangwana reMadivi maviri reSimba reHigh-Voltage

Nguva ye800V ichavewo nguva ye "Mobile Battery." Mota hadzizongotora magetsi chete; dzichaadzorera.

5.1 Kuyerera Kwesimba Kumativi Maviri

Nesarudzo yemagetsi maviri, mayuniti eMIDA anosungirirwa pamadziro anogona kutsigira:

• V2G (Mota kubva kuGrid):Kubatsira maturusi emagetsi kuti aenzane negridi panguva yekuremerwa kwakanyanya nekudhonza simba kubva kuma EV akamiswa.
• V2B/V2H (Motokari kubva pakuvaka/pamba):Kushandisa rori yemagetsi kupa simba kuhofisi panguva yekudzima magetsi kana kuderedza mari yekushandisa simba rezuva rakachengetwa husiku.
• Kubatsira kweHigh-Voltage muV2X:Kuburitsa bhatiri re800V kunoshanda zvakanyanya pane kuburitsa bhatiri re400V, sezvo kurasikirwa kwekushandura kwakaderera.

6. Mazano eHurongwa hweVaridzi veZvivakwa

Kana uri kuronga chirongwa chekuchaja mota dzemagetsi nhasi, tevera mitemo mitatu iyi kuchengetedza mari yako yekudyara:

1. Usambofa watenga hardware ine simba re500V.Zvakafanana nekutenga foni ye3G munyika ine 5G. Mukati memakore matatu kusvika mashanu, 800V ndiyo inenge yava kushandiswa zvakanyanya.
2. Isa Simba Rakawanda Pamberi.Sezvo mitengo yezvivakwa ichikwira, kugona kuisa unit ine simba re80kW pamadziro (panzvimbo pekabhineti yepasi) mukana mukuru wekukwikwidzana.
3. Iva nechokwadi chekuti Modularity.Sarudza masisitimu akaita seMIDA uko mamodule emagetsi anogona kuvandudzwa kana kutsiviwa zviri nyore. Nhevedzano yeWY yakagadzirirwa hupenyu hwebasa hwemakore gumi nemashanu ine zvikamu zvinochinjika zvemodular.

7. Mhedziso: Kutungamira Chimurenga che800V

Kuchinja kwekushandisa EV charging ine voltage yepamusoro hakusi tsika; ishanduko huru mufizikisi yekufamba. Machaja eDC ane 1000V eMIDA New Energy ndiwo mhinduro chaiyo yenguva itsva ino. Nekubatanidza kugona kwemagetsi ane voltage yakawanda nekushanda zvakanaka kweSiC uye dhizaini yemodular, MIDA inopa maturusi ayo mabhizinesi nevanoshanda muzvikepe vanoda kuisa mari yavo nechivimbo. Usangovaka mota dzanhasi chete; gadzira mota dzemakore gumi anotevera. Famba munguva ye800V neMIDA.
