–Ki te hiahia koe ki te utu tere mō tō waka hiko, kāore e hē te whakamahi i te hangarau ngaohiko teitei, au teitei mō ngā puranga utu.

Hangarau au teitei me te ngaohiko teitei

I te piki haere o te whānuitanga o te hiko, kei reira ngā wero pēnei i te whakapoto i te wā utu me te whakaiti i te utu o te mana, ā, ko te mahi tuatahi ko te arotau i te rahi o te kōwae kia tutuki ai ngā whakapainga hiko. Mai i te mana o tepuranga utuKo te nuinga o te wā, e whakawhirinaki ana ki te kaha o te waeine utu, ā, e herea ana e te rahinga o te hua, te wāhi papa me te utu hanga, ko te whakanui noa i te maha o ngā waeine ehara i te otinga pai. Nō reira, ko te whakanui ake i te kaha o tētahi waeine kotahi me te kore e tāpiri atu i te rahinga kua noho hei raruraru hangarau engā kaihanga mōrahi utume wikitoria wawe.

Ngā taputapu utu DCKa tutuki te kaha utu tere pai rawa atu mā te hangarau au-rahi me te ngaohiko-tiketike. Mā te piki haere o te ngaohiko me te mana, ka puta ake ngā whakaritenga tino pakari mō te mahi pumau, te tohatoha wera pai me te whai huatanga o te huringa o te waeine utu, e kore e kore ka whakatū i ngā wero hangarau teitei ake mō ngā kaihanga waeine utu.

I te aroaro o te hiahia o te mākete mō te utu tere kaha-teitei, me auaha tonu ngā kaihanga waeine utu me te whakapai ake i te hangarau matua, me te hanga i ā rātou ake arai hangarau matua. Ka waiho tēnei hei kī ki te whakataetae mākete ā muri ake nei, mā te mōhio ki te hangarau matua, kia kore ai e taea te hinga i roto i te whakataetae mākete nui.

1) Ara au-teitei: he iti te taumata o te whakatairanga, ā, he teitei ngā whakaritenga mō te whakahaere wera. E ai ki te ture a Joule (tātai Q=I2Rt), ko te pikinga o te au ka tino whakanui ake i te wera i te wā e utu ana, he nui ngā whakaritenga mō te tohatoha wera, pērā i te otinga utu tere au-teitei a Tesla, ko tana puranga utu nui V3 he nui ake te au mahi teitei o te 600A, e hiahia ana ki te whitiki waea matotoru ake, ā, i te wa ano, he nui ake ngā whakaritenga mō te hangarau tohatoha wera, ā, ka taea anake te whakatutuki i te mana utu mōrahi o te 250kW i roto i te 5%-27% SOC, ā, kāore anō kia tino hipokina te utu whai hua. I tēnei wā, kāore anō kia hangaia e ngā kaihanga motuka ā-rohe he huringa nui i roto i te kaupapa tohatoha wera, ā,ngā puranga utu au teiteihe nui te whakawhirinaki ki ngā pūnaha i hangaia e rātou anō, ā, ka nui ake ngā utu whakatairanga.

2) Ara hiko-tiketike: He momo e whakamahia whānuitia ana e ngā kaihanga waka, e taea ai te whakaaro ki ngā painga o te whakaiti i te whakapaunga pūngao, te whakapai ake i te roa o te pākahiko, te whakaiti i te taumaha, me te penapena wāhi. I tēnei wā, e whakawhāitihia ana e te kaha o te kaha o ngā taputapu hiko IGBT e ahu mai ana i te silicon, ko te otinga utu tere e whakamahia whānuitia ana e ngā kamupene waka he tūāpapa hiko-tiketike 400V, arā, ka taea te whakatutuki i te mana utu o te 100kW me te iahiko o te 250A (ka taea te utu i te mana 100kW mō te 10 meneti mō te 100km). Mai i te whakarewatanga o te tūāpapa hiko-tiketike 800V a Porsche (e whakatutuki ana i te mana 300KW me te haurua o te taura waea hiko-tiketike), kua tīmata ngā kamupene waka nui ki te rangahau me te whakatakotoranga i te tūāpapa hiko-tiketike 800V. Ki te whakatauritea ki te tūāpapa 400V, he iti ake te iahiko whakahaere o te tūāpapa hiko-tiketike 800V, e penapena ana i te rahinga o te taura waea, e whakaiti ana i te ngaronga ātete o roto o te ara iahiko, ā, e whakapai ake ana i te kiato mana me te whai huatanga o te pūngao.

I tēnei wā, ko te whānuitanga o te ngaohiko putanga mana pumau o te waeine matua 40kW o te umanga ko te 300Vdc~1000Vdc, e hototahi ana ki ngā hiahia utu o ngā waka pāhihi tūāpapa 400V o nāianei, ngā pahi 750V me ngā waka tūāpapa ngaohiko teitei 800V-1000V o muri mai; Ka taea e te whānuitanga ngaohiko putanga o te waeine 40kW o Infineon, Telai me Shenghong te eke ki te 50Vdc~1000Vdc, me te whakaaro ki ngā hiahia utu o ngā waka ngaohiko iti. Mō te whai huatanga mahi whānui o te waeine, ko ngā waeine whai huatanga teitei 40kW oTe Mana o BeiHaiwhakamahi i ngā taputapu hiko SIC, ā, ka taea e te tino whai huatanga te eke ki te 97%, he teitei ake i te toharite o te ahumahi.
