I te tere o te whanaketanga o te mākete EV, kua noho ngā puranga utu DC hei wāhanga nui o te hanganga utu EV nā ō rātou ake āhuatanga, ā, kua piki haere te hiranga o ngā teihana utu DC. Ki te whakatauritea ki ngā puranga utu AC,Ngā puranga utu DCka taea te tuku hiko DC tika ki ngā pākahiko EV, ka whakaiti i te wā utu, ā, ko te tikanga ka utuhia ki te 80 ōrau i roto i te iti iho i te 30 meneti. Nā tēnei tikanga utu whai hua ka nui ake te whakamahinga i teNgā puranga utu ACi ngā wāhi pēnei i ngā teihana utu tūmatanui, ngā pokapū arumoni me ngā wāhi ratonga huarahi tere.
Mō te kaupapa hangarau, ko te nuinga o te puranga utu DC ka huri i te hiko mā te tuku hiko whakawhiti auau-teitei me te waeine hiko. Kei roto i tōna hanganga o roto ko te whakatikatika, te tātari me te pūnaha whakahaere hei whakarite i te pumau me te haumaru o te iahiko putanga. I taua wā, ko ngā āhuatanga atamai oNgā puranga utu DCka āta whakarei ake, ā, he maha ngā hua kua rite ki ngā atanga whakawhitiwhiti kōrero e āhei ai te taunekeneke raraunga wā-tūturu me ngā EV me ngā whatunga hiko hei arotau i te tukanga utu me te whakahaere whakapaunga pūngao. Ko tōna kaupapa matua hangarau ko ngā āhuatanga e whai ake nei:
1. Tukanga whakatikatika: He whakatikatika ā-roto kei roto i ngā puranga utu DC hei whakatutuki i te utunga mā te huri i te mana AC ki te mana DC. Kei roto i tēnei tukanga te mahi tahi a ngā diode maha hei huri i te haurua-wiki pai me te haurua-wiki kino o te AC ki te DC.
2. Te Tātari me te Whakahaere Ngaohiko: Ka whakangawaritia te mana DC kua hurihia e te tātari hei whakakore i ngā piki me ngā heke o te iahiko putanga, hei whakarite hoki i te pumau o te iahiko putanga. Hei tāpiri, ka whakahaeretia e te kaiwhakahaere ngaohiko te ngaohiko kia mau tonu ai te ngaohiko i roto i te awhe haumaru i te wā e utua ana.
3. Pūnaha whakahaere atamai: Kei ngā puranga utu DC hou he pūnaha whakahaere atamai e aroturuki ana i te tūnga utu i te wā tūturu, ā, ka whakarerekē hihiri i te iahiko me te ngaohiko utu hei whakapai ake i te whai huatanga o te utu me te tiaki i te pākahiko ki te taumata teitei.
4. Ngā kawa whakawhitiwhiti kōrero: Ko te whakawhitiwhiti kōrero i waenga i ngā rihi hiko DC me ngā EV e ahu mai ana i ngā kawa paerewa pēnei i te IEC 61850 me te ISO 15118, e āhei ai te whakawhitiwhiti kōrero i waenga i te rihi hiko me te waka, kia mau ai te haumaru me te whai huatanga o te tukanga utu.
Mō ngā paerewa hua pou utu, ka whai ngā pou utu DC i ētahi paerewa o te ao me te motu hei whakarite i te haumaru me te hototahi. Ko te paerewa IEC 61851 i whakaputaina e te International Electrotechnical Commission (IEC) e whakarato ana i ngā aratohu mō te hononga i waenga i ngā EV me ngā whakaurunga utu, e kapi ana i ngā atanga hiko me ngā kawa whakawhitiwhiti kōrero. Ko tā HainaGB/T 2023I tētahi atu taha, kei roto i te paerewa 4 ngā whakaritenga hangarau me ngā whakaritenga haumaru mō ngā pou utu. Ka whakahaeretia e ēnei paerewa katoa ngā paerewa o te umanga hanga me te hoahoa pou utu ki tētahi taumata, ā, ki tētahi taumata, ka āwhina ki te whakatairanga i te whanaketanga hauora o te mākete mō ngā waka hiko pūngao hou me ā rātou umanga tautoko.
E ai ki te momo pū utu o te puranga utu DC, ka taea te wehewehe i te puranga utu DC ki te puranga utu pū kotahi, pū rua, me te puranga utu pū maha. He pai ngā puranga utu pū kotahi mō ngā teihana utu iti, ko ngā puranga utu pū rua me ngā pū maha he pai mō ngā wāhi nui ake hei whakatutuki i te tono utu teitei ake. He tino rongonui ngā pou utu pū maha nā te mea ka taea te whakamahi mō ngā EV maha i te wā kotahi, ka tino whakanui ake i te pai o te utu.
Hei whakamutunga, ko te tirohanga mō te mākete puranga utu: he tino kaha te heke mai o ngā puranga utu DC i te whanaketanga o te hangarau me te tipu haere o te tono mākete. Mā te whakakotahitanga o ngā whatunga atamai, ngā waka kore taraiwa me te pūngao whakahou ka kawea mai he whai wāhitanga hou mō ngā puranga utu DC. Mā te whanaketanga tonu o te wā matomato, e whakapono ana mātou kāore e whakaratohia e ngā puranga utu DC he wheako utu watea ake ki ngā kaiwhakamahi, engari ka whai wāhi atu hoki ki te whanaketanga pumau o te pūnaha e-nekehanga katoa.
