Te Whakatere i te Wā 800V: Me pēhea te whakamahi a ngā Utauta Ngaohiko-Tiketike 1000V a MIDA hei Pūmau i tō Pūtea Hanganga ā-Mārama

Te Huringa Tauira: Mai i te 400V ki te 800V me tua atu

Mō te nuinga o te tekau tau kua pahure ake nei, kua whakamahia e te umanga waka hiko (EV) he hoahoa pākahiko 400V. He tīmatanga whaitake tēnei, e whakataurite ana i te mahi me ngā utu o ngā hikohiko mana. Heoi, kua tae tātou ki ngā rohe o ngā pūnaha 400V. Hei whakatutuki i te "utu 10-meneti" e hiahiatia ana e ngā kaihoko, kei te huri tere ngā kaihanga motuka ki ngā hoahoa 800V me 1000V. Kua whakarewahia e ngā waitohu pēnei i a Porsche, Hyundai, Kia, me Lucid ngā papaaho ngaohiko teitei, ā, kei te whai te umanga taraka arumoni i tēnei. Ko ngā rihi DC pakitara 40kW-80kW a MIDA New Energy kua hangaia hei piriti ki tēnei heke mai ngaohiko teitei.

1. Te Ahupūngao o te Tere: He aha i toa ai te Ngaohiko Teitei

Hei mārama ki te take e neke ai te ahumahi ki te 800V/1000V, me titiro tātou ki te tauira taketake mō te mana:Mana (Wāti) = Ngaohiko (Volts) × Iahiko (Amperes).

1.1 Te Raru Wera I²R

• Te Wero:I roto i tētahi pūnaha 400V, kia tukuna ai te 80kW o te mana, me pana e te rihi he 200 Amps o te iahiko. Ko te wera e puta ana i roto i tētahi ara iahiko he rite ki te tapawhā o te iahiko (P = I²R). Ka puta he wera nui mai i te iahiko teitei, ā, ka hiahiatia he taura matotoru, taumaha, he wai-whakamatao e utu nui ana, ā, he uaua hoki ki ngā kaiwhakamahi te whakamahi.
• Te Otinga Ngaohiko-Teitei:Mā te whakanui ake i te ngaohiko ki te 800V, ka taea te tuku i te 80kW o te mana me te 100 Amps anake o te iahiko. Mā tēnei ka māmā ake, ka ngāwari ake ngā taura, ka iti ake te moumou pūngao, ā, ka iti ake te ahotea wera i runga i ngā pūtau pākahiko o te waka me ngā ara iahiko o roto o te rihi.
• Te Whai Hua o te Pūnaha:Ka taea e ngā pūnaha 800V te whakaiti i ngā ngaronga utu tae atu ki te 30% ki te whakaritea ki ngā pūnaha 400V i te taumata mana kotahi.

1.2 Te tuanui 1000V a MIDA: Neke atu i te 800V

Ahakoa ko te kupu "800V" te kupu rongonui, he maha ngā waka e mahi ana i ngā ngaohiko i waenga i te 700V me te 920V. Kua hangaia ngā rihi MIDA me teTeihana putanga 1000V, e whakarato ana i tētahi awhe haumaru nui, me te whakarite i te hototahi ahakoa kei te neke atu ngā pākahiko o te whakatipuranga e whai ake nei i te tohu 800V ki te rohe 900V+.

2. Te Painga Whānui-Ngaohiko 1000V: Kotahi te Rīhi mō te Katoa

Ko te mōrearea nui rawa atu mō te kaipupuri moni hanganga ko te "tawhitotanga." Ko te rihi hiko kua tāutahia i ēnei rā ka taea anake te whakaputa 500V, kāore e taea te utu i tētahi waka 800V i tōna tere taketake, i ētahi wā rānei, kāore rawa e taea.

2.1 Te Āwhio Utu "Ao Whānui"

Kei roto i te raupapa WY a MIDA he whānuitanga putanga tino whānui mai i150V ki te 1000V.

• Ngaohiko Iti (150V-400V):He tino pai mō ngā EV tawhito (pērā i te Nissan Leaf o mua), ngā motopaika hiko, me ngā waka tuku taonga iti o te tāone.
• Ngaohiko Teitei (400V-1000V):He tino pai mō ngā sedan papai hou (Porsche Taycan, Lucid Air, Audi e-tron GT) me ngā papaaho mahi-teitei (Hyundai E-GMP, Kia EV6).
• Rohe Mana Pūmau:Ka mau tonu te putanga 60kW katoa o te waeine MIDA UR100060A mai i te 300V ki te 1000V. Ko te tikanga ka whiwhi te motuka he pākahiko 400V i te 60kW, ā, ka whiwhi te motuka he pākahiko 800Vhokika 60kW. He maha ngā wā ka whakaitihia te mana o ngā rihi tuku iho i te haurua ina utu ana i ngā pākahiko iti-ngaohiko.

3. SiC (Silicon Carbide): Te Mīhini Whai Hua Ngaohiko-Tiketike

Ko te tuku hiko 1000V mai i tētahi waeine pakitara kiato he wero hangarau kāore i taea e ngā hiko hiko tuku iho te whakatau. Kua whakatauhia tēnei e MIDA mā te whakauruKarāpi Hiraka (SiC)ngā haurua-ā-ira.

3.1 Te Ahupūngao Whānui o te Āputa Whanui (WBG)

He rauemi whānui te āputa irahiko o te SiC, arā, he nui ake tōna kaha pakaru hiko i te silicon.

• Whakaiti Rahi:Mā te SiC ka taea te whakamahi i ngā kōwae hiko iti ake. E 50% te iti ake o te UR100060 i tētahi kōwae rite tonu e hangai ana ki te silicon.
• Te Whai Hua o te Whakawhiti:Ka whakaitihia e te SiC ngā mate whakawhiti tae atu ki te 80%. He mea nui tēnei i ngā ngaohiko tiketike e nui ake ai te whai huatanga o ngā mate whakawhiti.
• Te Mahi Tino Pai:Ka mau tonu te pai o te mahi a te rihi MIDA e ahu mai ana i te SiC ki te >95% ahakoa kei te taha o tōna takai 1000V.

4. Hononga me te Roa o te Kawa: NACS, CCS, me te ISO 15118

Ehara i te mea ko te hiko anake te mea e hiahiatia ana hei whakarite mō ngā rā kei te heke mai; engari ko te whakawhitiwhiti kōrero.

4.1 Ngā Pakanga Hononga: NACS vs. CCS

Kei te huri haere te āhua o te utu.

• NACS (Paerewa Utu o Amerika Te Raki):Kei te whakamahia te paerewa a Tesla e Ford, GM, me Rivian. Kei te tuku a MIDA i ngā taura NACS kua whakauruhia ki te wheketere me te tautoko taketake mō te kawa whakawhitiwhiti kōrero a Tesla.
• CCS1 me CCS2:Ngā paerewa o te ao mō Amerika Te Raki me Ūropi. Mā te hoahoa hononga ā-pūrere a MIDA ka taea te whakawhiti i ngā taura mēnā ka neke te paerewa mākete ā-rohe, ka tiakina te haumitanga o te kāpata hiko kei raro.
• Whakawhiti Hihiri:Ka taea e te pūmana o MIDA te kite mēnā kei te kōrero ia ki tētahi waka CCS, NACS rānei, ā, ka taea e ia te whakawhiti aunoa i ngā kawa.

4.2 ISO 15118-20: Mono & Utu me tua atu

Kua rite ngā taputapu a MIDA mō ngā mea houISO 15118-20paerewa.

• Mono & Utu:Kāore he kāri RFID. Ka tautuhia e te motuka ia ki te rihi, ka whakahaere i te rūrū haumaru, ā, ka tukuna aunoa he pire ki te pūkete a te rangatira.
• Haumarutanga Matatau:Ka whakamahia e te ISO 15118-20 te whakamunatanga TLS 1.3, kia kore ai e taea e ngā kaipahua te whakawhitiwhiti kōrero i waenga i te motuka me te taputapu utu (tae atu ki ngā raraunga utu).

5. V2X: Te Anamata Ahu-rua o te Pūngao Ngaohiko-Tiketike

Ko te wā 800V hoki te wā o te "Pūhiko Pūkoro." E kore e tangohia noa e ngā waka te hiko; ka whakahokia mai anō hoki.

5.1 Rere Pūngao Ahu-rua

Mā ngā kōwae hiko rua-ara kōwhiringa, ka taea e ngā waeine MIDA e mau ana ki te pakitara te tautoko i:

• V2G (Waka-ki-Whatunga):Te āwhina i ngā ratonga whakahaere ki te whakataurite i te whatunga hiko i te wā e tino pīrahi ana ngā kawenga mā te tango i te hiko mai i ngā EV e tū ana.
• V2B/V2H (Waka-ki-te-Whare/Kāinga):Te whakamahi i tētahi taraka hiko hei whakakaha i tētahi whare tari i te wā e pōuri ana, te whakaiti rānei i ngā utu pūngao mā te whakamahi i te hiko o te rā kua rongoatia i te pō.
• Painga Ngaohiko-Tiketike i roto i te V2X:He nui ake te whai hua o te tuku hiko i te pākahiko 800V i te tuku hiko i te pākahiko 400V, nā te mea he iti ake ngā mate huringa.

6. Tohutohu Rautaki mō ngā Kaipakihi Hanganga

Mena kei te whakamahere koe i tētahi kaupapa utu EV i tēnei rā, whai i ēnei ture e toru hei tiaki i tō haumitanga:

1. Kaua rawa e hoko taputapu iti-500V.He rite tonu ki te hoko waea 3G i roto i te ao 5G. I roto i ngā tau 3-5, ka noho ko te 800V te paerewa matua.
2. Whakatairangahia te Kiato Mana.I te pikinga ake o ngā utu mō ngā whenua, he painga nui ki te whakataetae te kaha ki te whakairi i tētahi waeine kaha 80kW ki runga i te pakitara (kaua ki runga i tētahi kāpata papa).
3. Kia Whakarite i te Modularity.Kōwhiria ngā pūnaha pēnei i a MIDA e taea ai te whakapai ake, te whakakapi rānei i ngā waeine hiko. Kua hangaia te raupapa WY mō te roanga ratonga 15 tau me ngā wāhanga ka taea te whakawhiti waeine.

7. Whakamutunga: Te ārahi i te Huringa 800V

Ehara te neke ki te utu hiko EV ngaohiko teitei i te mea auaha; he panonitanga nui i roto i te ahupūngao o te nekenekehanga. Ko ngā utu hiko DC e mau ana ki te pakitara 1000V a MIDA New Energy te otinga tino pai mō tēnei wā hou. Mā te whakakotahi i te kaha ngaohiko teitei me te whai huatanga SiC me te hoahoa modular, ka whakaratohia e MIDA ngā taputapu e hiahiatia ana e ngā pakihi me ngā kaiwhakahaere waka hei haumi me te maia. Kaua e hanga noa mō ngā motuka o ēnei rā; hanga mō ngā motuka o te tekau tau e whai ake nei. Whakatere i te wā 800V me MIDA.
