Te Whakaurunga Pūngao-Rā-Rokiroki-Utu: Te Otinga Tino Kore-Tukunga

Whakautu Tere:Ka whakauruhia e te pūnaha penapena-rā-whakautu (PV + BESS + EV) te whakaputanga photovoltaic, te pūnaha rokiroki pūngao pākahiko (BESS), me te utu tere DC ki roto i tētahi hoahoa atamai-pūnaha kotahi e taea ai e tētahi wāhi utu te whakaputa i tana ake pūngao ma, te penapena, te tuku ki ngā waka, tae atu ki te hoko atu ki te pūnaha. I te tau 2026, koinei anake te tauira utu e whakakore ana i ngā tukunga hiko o te paipa hiko, e tango ana i ngā aukati kaha-pūnaha, ā, e huri ana i te hiko mai i te pokapū utu hei rawa moni whiwhi — ka waiho hei otinga kore-tukunga mō ngā hanganga EV arumoni.

Kupu Whakataki

Ko te whakaurunga o te hiko pūngao-rā ko te huihuinga o ngā hangarau pakari e toru — te photovoltaics (PV), te rokiroki pūngao pākahiko (BESS), me te utu hiko EV e rua ngā taha — ki roto i te pūnaha pūngao kua arotauhia, ā, kua waiho hei hoahoa tohutoro mō ngā kaupapa hiko arumoni nui katoa i te tau 2026. Ka tangohia noa e te teihana utu tere tikanga ngā kilowatts mai i te whatunga tohatoha i te wā e tae mai ai te motuka; engari ko te wāhi utu rokiroki pūngao-rā whakauru ka whakamahere, ka penapena, ka whakatau i tōna pūngao, kia taea ai e ia te utu i ngā waka ki te mana katoa ahakoa te ngoikore o te whatunga, kua tō te rā, kei te tino tiketike rānei ngā utu hiko.

Ko te raruraru e whakatauhia ana e ia he hanganga. Ka tae mai ngā kawenga utu tere DC o te 120 kW ki te 480 kW i roto i ngā pakūnga kore e taea te matapae, ā, ka piki haere te whakahē a ngā kamupene hiko i ngā tono hononga mō ngā wāhi kāore e taea te whakaatu ka taea e rātou te whakahaere i tā rātou hiahia nui. I taua wā anō, he mea wā poto te whakaputanga hiko o te rā - he toenga i te poutumarotanga, he ngoikoretanga i te ahiahi - koinei te hurihanga tika o te hiahia utu. Ka taea te aukati i tētahi utu takitahi e te kaha o te whakawhiti hiko, te pehi i ngā utu tono, me te kati i ngā pōuri. Ka whakakorehia e te pūnaha utu rokiroki-rā ngā momo rahunga e toru nā te mea ka mahi te BESS hei ārai i waenga i te rā, te whatunga hiko, me te waka.

Kāore te take pakihi e waiho hei ariā noa iho. Nā te mea kei raro iho i te $100/kWh ngā utu mōkihi pākahiko i te taumata pūnaha i te nuinga o ngā mākete, ā, kua neke atu i te 96% te whai huatanga o ngā inverter, ka tukuna e ngā pae whakauru he utu whakahoki mō te 3–6 tau i ngā rohe he nui ngā horapa utu i te wā pīki, me te ārai i ngā kaiwhakahaere mai i te piki me te heke o te utu pūngao ā muri ake nei. Ka hangaia e MIDA ngā wāhanga nui katoa o tēnei hoahoanga — mai iNgā kōwae mana pūngao rā MPPTka hauhake tika i te PV ki runga i te pahi DC, kingā kōwae hiko AC-DC e rua ngā ahungameNgā otinga utu V2Ge tuku ana i te pūngao kua rongoatia kia rere ki ngā taha e rua — kia taea ai te hanga i te pūnaha katoa hei hua kotahi, he hua whaimana, kaua hei huinga pouaka tuatoru.

Kua eke te taiao ture ki te taumata teitei, ā, ko te tau 2026 te pūwāhi e huri ai. Ko ngā putanga hou o ngā paerewa whakahaere — IEC 61851-23:2023 mō te utunga DC (e whakahau ana i te tautoko tūāpapa 1000V+, te whakamātautau-ā-roto aroturuki whakamahana, me ngā whakaritenga haumaru whakawhiti hiko e rua-ara) me te ISO 15118-20:2022 mō te Mono & Utu me te whakawhitiwhitinga e rua-ara — kua huri i te V2G mai i te kaupapa whakamātautau hei āhuatanga rite ki te tutuki i ngā ture. Ko ngā kaiwhakahaere e hanga ana i ngā pae whakauru inaianei kāore e tango i tētahi whakamātautau; kei te tango rātou i te paerewa mō te tekau tau e whai ake nei o te hanganga utunga.

Ngā Whakaaro Matua

• Kotahi te hoahoanga, e whā ngā huanga moni whiwhi:Ka whiwhi moni te pae utu PV-BESS whakauru mai i te whakatau tata pūngao, te karo i te utu tono, te whai wāhi ki te urupare tono, me ngā hoko utu — ko te teihana takitahi ka whiwhi moni mai i ngā hoko utu anake.
• Ko te whai huatanga te mea e rerekē ai:Kua eke te whai huatanga o te hurihanga utu DC a MIDA≥96.5%i raro i te kawenga katoa, ā, ko tōna kaitahuri rokiroki 30 kVA (PCS) ka eke ki te taumata teitei i97.1%, e whakaiti tika ana i ngā ngaronga pūngao me ngā utu whakahaere.
• Te rite katoa o te tūāpapa ngaohiko:ka whakahaerehia ngā kōwae hiko e rua ngā ahunga me ngā kōwae hiko V2G puta noa i te150V–1000V DCte whānuitanga, e hanga ana i ngā pae kia hototahi ki ngā kahui waka 400V o ēnei rā me te whakatupuranga e whai ake nei o ngā EV ngaohiko-tiketike 800V/1000V.
• Ka kapi te rahi o te BESS i te whakamahinga katoa:Mai i ngā teihana whakaora ohorere 65–200 kWh ki ngā pūnaha utu hiko pūngao rā 800–2,000 kWh, he taumata rokiroki mō ia momo papa.
• Ka eke a V2G ki te taumata paerewa i te tau 2026:E tautokona ana te ISO 15118-2 / ISO 15118-20:2022 (Pūrua me te Utu me te whakawhiti hiko taha-rua) me te DIN 70121 mai i te tīmatanga, e āhei ai te tukunga hiko mai i te waka ki te whatunga e tutuki ana i ngā whakaritenga waehere whatunga.
• Kei roto i te hanganga o te manawanui:Ka ora tonu ngā pae whatunga-iti e āhei ana ki te tiaki i ngā moutere, e ai ki te IEC 61851-23:2023, i te wā e motu ana te hiko — he rerekētanga tēnei i ngā rohe he pakarukaru ngā whatunga hiko.
• I hinga te utu tuatahi i te TCO:E kore e nui ake i te $5,000 te whakapaunga hiko o tētahi rihi hiko iti-te-pai (≈91%) mō ngā tau e toru i tētahi pūnaha kotahi 120 kW, ki te whakaritea ki tētahi pūnaha ≥96.5% — ko te āputa pai anake he nui ake i te utu tīmatanga.

Ruku Hōhonu: Ngā Pou e Whā o te Whakaurunga Pūngao-Rā-Rokiroki-Utu

Ko te wāhi whakauru he mea tino mārama ki te hoahoa hiko e toru ngā wāhanga i roto i te kāpata kotahi, i te whatunga iti rānei. Ko te wāhanga tuatahi ko te tāuru PV: he kaitahuri MPPT (Maximum Power Point Tracking) e tango ana i te mana tihi mai i te huinga hiko rā, ka whāngai tika atu ki te pahi DC. Ko te wāhanga tuarua ko te wāhanga AC-DC e rua ngā ahunga: he kaitahuri e utu ana i te pākahiko mai i te whatunga, i te PV rānei, ā, ka huri i te DC kua rongoatia ki te AC i te wā e kaweake ana. Ko te wāhanga tuatoru ko te wāhanga DC-DC motuhake e tuku ana i te kōtaha ngaohiko me te iahiko tika e hiahiatia ana e ia waka hono. Ina tohaina e ēnei wāhanga e toru he pahi DC noa, ka taea e te pūngao PV te utu i te waka me te kotahi noa te huringa - te karo i ngā ngaronga huringa-rua o ngā hoahoa AC-honohono - ā, ka taea e te pākahiko te mimiti, te tuku rānei i te mana i roto i ngā mirihekona hei whakangawari i te tapuwae whatunga o te wāhi. Ko ngā wāhanga e whā i raro nei e whakamārama ana i te uara whakahaere o tēnei hoahoa.

1. Whatunga-iti: Te Huri i tētahi Pae Utu hei Moutere Pūngao Whaiaro-Taurite

Ko te pūnaha utu-pūngao-rā, e ai ki te whakamāramatanga, he whatunga-iti DC — he whatunga hiko ā-rohe ka taea te whakataurite i tana ake whakaputanga, rokiroki, me te kawenga me te kore e tango i te kotahi kilowati mai i te pūnaha whakahaere, ā, ko MIDAngā pūnaha rokiroki pūngao pākahikomengā teihana utu BESS whakaurukua hangaia kia mahi i tēnei aratau. I roto i te mahi moutere, ko te arai PV te pūtake pūngao matua, ko te BESS te punga ngaohiko me te auau, ā, ko ngā rihi EV he kawenga ka taea te whakahaere; ina kaha te rā, ā, kua kī te pākahiko, ka kaweake te papa i te pūngao taikaha, ā, ina piki te kawenga, ka taupokina e te pākahiko i te wā tūturu kaua ki te hononga ratonga.

Kāore e taea te whiriwhiri i ngā whakaritenga hangarau mō te noho haumaru i runga i te moutere, ā, kua whakarārangihia inaianei. I raro i te IEC 61851-23:2023, me tutuki i tētahi pūnaha e tautoko ana i te whakawhiti hiko ā-rua (BPT) ngā whakaritenga taumata-āpiti mō te haumaru hononga whatunga, tae atu ki te kimi ārai-moutere e momotu ana i te pae mai i tētahi whatunga whakakore-hiko i roto i te matapihi kimi e hiahiatia ana, me tētahi taputapu aroturuki whakamarumaru whaiaro (IMD) e manatoko tonu ana i te wehenga i te 1000V+ DC. Koia te take he mea whakahau ngā kaitahuri rokiroki kua whakamanahia, kua hangaia mō tētahi kaupapa motuhake - kaua ki ngā waeine UPS kua whakarerekētia - mō ngā pae utu whatunga moroiti.

Mō ngā kaiwhakahaere, ka taea e te āheinga whatunga-iti te huri i te hanganga utu mai i te nama hei rawa. Ka taea e te wāhi he pākahiko 200 kWh me te 120 kW o te utu te whakahaere i roto i te motuhanga maha-hāora, te pupuri i ngā taraka utu kia neke i te wā urupare ohorere, ā, ka whai mana ki ngā whakatenatena i roto i ngā mākete e utu ana mō ngā whatunga-iti tautoko whatunga. Nā tēnei pakari kua puta he kāwai hua katoa — ngā teihana utu whakaora ohorere 65–200 kWh — ka tukuna e MIDA hei waeine hiko pūkoro, rite ki te whatunga-iti mō ngā waka, ngā kaihokohoko, me ngā ara urupare ā-aituā.

2. Te Heu Tino Pai: Te Whakaiti i ngā Utu Tono i te Pūtake

Ko te heu tihi ko te mahi o te whakawhāiti i te kawemai o te whatunga hiko o te papaanga i te tuanui kua whakawhāitihia mā te tuku i te BESS i ngā wā e pau ana te hiko i te papaanga, ā, koinei te nuinga o te wā te utu nui rawa atu i roto i te ōhanga o te papaanga whakauru nā te mea ko ngā utu tono (utu kaha) he maha ngā wā e 30–50% o te pire hiko arumoni. He māmā noa te tikanga: ka utu te pākahiko i te tere iti, pumau i ngā wā kore-pīki - i te nuinga o te wā i te pō, i te poutumarotanga rānei o te rā - ā, ka tukuna taua pūngao i te wā e pau ana te hiko, kia kore ai te whakawhiti hiko me te mita e kite i te 350 kW katoa e hiahiatia ana e ngā rihi hiko e ono 60 kW i te wā kotahi.

Ko te pānga pūtea e whakaaturia ana e tētahi pokapū rahi-waenga noa: ko tētahi wāhi he 350 kW te tihi ine me te utu tono $12/kW-marama e utu ana i te $4,200 ia marama hei utu kaha anake. Mā te tango i te 40% o taua tihi me te BESS 215 kWh ka whakaitihia te pire ki te $2,520 ia marama — he penapena $20,000 ia tau — e i te nuinga o ngā mākete ka whakakore katoa i te haumi rokiroki i roto i ngā tau e toru. Ka tāpirihia e te whakataunga pūngao tētahi atu paparanga moni whiwhi: mā te utu 215 kWh i te tere $0.05/kWh i waho o te wā pīki, me te tango i ngā hoko pīki $0.15/kWh ka penapenahia te $21.5 ia huringa, tata ki te $1,290 ia marama i ngā huringa e rua ia rā.

Ko te whakatau i te rahi e whai ana i tētahi tikanga māmā mō te nuinga o ngā pae arumoni: te whakatau i te rahi o te pākahiko ki te 40–60% o te kaha utu o ia rā o te pae, me te tere tukunga C o te 0.5C, iti iho rānei mō te roa o te huringa. Mō te pokapū utu tere 1,000 kWh/rā, e tohu ana tēnā i tētahi BESS 400–600 kWh me te kaha tukunga 200–300 kW — he whirihoranga kua hangaia e ngā puranga utu ESS whakauru 60–400 kW a MIDA hei tuku i roto i te tapuwae kotahi, me ngā waeine hiko, te whakahaere pākahiko, me te whakamatao kua whakauruhia ki te wheketere, kaua ki te huihui ki te pae.

3. Te Whakautu i te Hiahia: Te Huri i ngā Teihana Utu hei Rawa Whatunga

Ko te urupare tono (DR) te tikanga e whiwhi ai tētahi pae utu whakauru i ngā utu tika hei tuku i te kaiwhakahaere whatunga hiko, i tētahi kaiwhakakotahi rānei ki te whakahaere, ki te tuku rānei i tana kawenga me te rokiroki ngāwari, ā, he mea tino whai hua te pae utu PV-BESS i ngā mākete DR nā te mea ka taea e ia te urupare i roto i ngā mirihekona me te kore e whakaiti i te wheako utu a te kiritaki. Me whakaheke te kawenga o tētahi rihi takitahi e whai wāhi ana ki te DR — he taraiwa hoha — engari ka neke noa te pae e tautokona ana e te rokiroki ki te mana pākahiko, ka kaweake rānei ki te whatunga hiko, nō reira ka mau tonu te utu a te waka i te mea ka whiwhi te pae i ngā utu kaha, ngā utu pūngao, me ngā moni whiwhi ratonga tāpiri mō te whakahaere auau.

Ko te paparanga whakahaere e āhei ai tēnei ko te pakari o ngā kawa. Ka whakahaerehia e ngā pae hou te OCPP 1.6J, 2.0.1 rānei i te taumata whakahaere-utu me te ISO 15118-20:2022 i te taumata whakawhitiwhiti-waka, e hoatu ana ki te kaiwhakahaere pae ngā matau telemetry me te whakaritenga e hiahiatia ana e ngā kaiwhakakotahi: te āhua utu wā-tūturu o te BESS, ngā matapae pūngao mō ia wātū, me te kaha ki te whakahaere i tētahi tohu tuku DR i roto i te matapihi urupare a te ratonga. Kātahi ka arotauhia e tētahi pūnaha whakahaere pūngao ā-rohe (EMS) i waenga i ngā tohu whakataetae e toru - te utu wāhi, te tuku DR, me te tono utu - i te wā-tūturu.

Ko te tono tino nui ko te whakahaere auau, me mimiti, me wero rānei te hiko e te kaitahuri rua-aronga i roto i ngā hēkona. Ko ngā kōwae rua-aronga 30–62.5 kW a MIDA, me te pai o te tahuritanga tae atu ki te 96%, he tika te rahi mō tēnei mahi: ka taea e te pākahiko 500 kWh i muri i ngā kōwae e ono 62.5 kW te tono i ētahi megawatts o te ruma upoko tere ki roto i te mākete ture. I roto i te tau kirimana, he maha ngā wā ka whakataetae ngā moni whiwhi ture - ā, i roto i ētahi mākete Pākehā me Amerika Te Raki - i te tawhē utu tonu, koia te take e piki haere ana te rārangi a ngā kamupene ratonga i ngā wāhi rokiroki whakauru hei rawa pai i roto i ngā hokohoko kaha.

4. Ngā Hurihuri Ahu-rua e Hangai ana ki te SiC: Te Tuarā o te Hikohiko Mana

Ko ngā haurua hiko-warohiko (SiC) te take e tutuki ai i ngā kaitahuri rua-aronga o ēnei rā te whai huatanga, te mātotorutanga, me te pono e whai hua ai te tauira utu-pūkoro-rā katoa, ā, ko ia waeine rua-aronga me te V2G i roto i te putea MIDA he mea hanga ki runga i te āhua motuhake auau-teitei e hangai ana ki te SiC. Ki te whakatauritea ki ngā hoahoa IGBT silicon tuku iho, ka huri ngā taputapu SiC i ngā auau teitei ake me ngā ngaronga whakawhiti iti rawa, e whai hua ana ki ngā painga e toru: te whai huatanga tahuritanga neke atu i te 96% (tae atu ki te 96.5% mō te ara utu DC me te 97.1% mō te kaitahuri rokiroki), tata ki te 30–40% iti ake ngā wāhanga aukume, me te whanonga wera pai ake e āhei ai te mahi whakamatao-wai mō ngā kāpata mana-teitei.

Nā te hurihanga 1000V, ka hiahiatia te SiC, kaua ko te mea whiriwhiri. Ko ngā papaaho EV 800V me te 1000V o te whakatipuranga e whai ake nei e hiahia ana ki ngā kaitahuri ka taea te whakahaere i te awhe DC 150V–1000V me te pupuri tonu i te whai huatanga i ngā pito rawa; ka tukuna hoki e te whānuitanga whānui o te SiC te takai tere mō te whakakore hapa me te iti o te ine hiko e hiahiatia ana e te aroturukitanga whakamarumaru me te haumaru hapa-arc i ēnei ngaohiko. Mō ngā pae 350 kW+, kua whakarārangihia e te IEC 62196-3:2022 ngā whakaritenga haumaru whakamatao-wai — te aroturukitanga pēhanga porowhita whakamatao me te whakahaere pikinga pāmahana — e pupuri ana i ngā wāhanga mana SiC i roto i tō rātou rohe whakahaere haumaru i raro i te mahi mana-teitei tonu.

Me whakanui te pāngarau ōhanga o te whai huatanga. Mena ka oma te rihi hiko 120 kW mō ngā hāora 10 ia rā i te kawenga katoa, ka moumou te kaitahuri 91%-whai hua i te 7.2 kW ia hāora hei wera; ka moumou noa te pūnaha 96.5% i te 4.2 kW — he rerekētanga tata ki te 10,900 kWh ia tau, he nui ake te uara i te $1,000 ia tau i te nuinga o ngā mākete, ā, neke atu i te $5,000 i roto i ngā tau e toru. Ko taua āputa whai huatanga, e piki haere ana puta noa i ia kokoru o ia wāhi, koinei te take kāore te kōwae iti rawa te utu i te pūnaha iti rawa te utu, ā, koinei te take e tohua ai e ngā kaiwhakahaere nui ngā kaitahuri SiC rua-aronga hei matua kore e taea te whiriwhiri mō ā rātou wāhi whakauru.

Te whakataurite i te hoahoanga — te tū motuhake me te whakauru:

Ngā Pātai Auau

1. He aha te pūnaha whakauru pūngao-rā-pūnaha-whakautu?

Ka whakakotahihia e te pūnaha whakauru-pūnaha-whakautu-rā te whakaputa hiko photovoltaic (PV), te pūnaha rokiroki pūngao pākahiko (BESS), me te utu EV ki roto i te hoahoa pūngao kotahi. Ka whakaputahia te hiko e ngā panera rā, ka rongoatia e te pākahiko, ā, ka tukuna e ngā utu ki ngā waka — me ngā kaitahuri-rua-ara (V2G) e tuku ana i te pūngao kua rongoatia kia rere anō ki te whatunga hiko. Nā te mea he pahi DC noa ngā wāhanga e toru, ka taea e te mana PV te utu i tētahi motuka mā te huringa kotahi, ā, ka ārai te pākahiko i te whatunga hiko, te whakaputa, me te kawenga i te wā tūturu.

2. E hia te nui o te penapena e taea ana e te heu tere i runga i ngā pire hiko?

Ko te tikanga, ka whakaitihia e te heu werawera te tapeke o ngā utu hiko mā te 20–40% i ngā wāhi e 30–50% o te pire te nui o ngā utu tono. I roto i te tauira i runga ake nei, ko te wāhi e 350 kW te kaha, e $12/kW te kaha, e utu tono ana i te $20,000 pea ia tau mā te whakawhāiti i tōna kaha ki te BESS 215 kWh. Ko ngā penapena tika e whakawhirinaki ana ki tō hanganga utu, te horapa utu mai i te kaha ki waho o te kaha, me te kōtaha utu - ko te nui ake o te horapa me te koi ake o ngā kaha, ko te tere ake o te utu o te rokiroki.

3. Ka taea tonu e te teihana utu pūngao-rā te mahi ahakoa te motuhanga o te hiko?

Āe, mēnā kua hangaia te pūnaha, ā, kua whakamanahia hoki mō te mahi whatunga iti/motu. I te aratau moutere, ka herea e te BESS te ngaohiko me te auau o te whatunga ā-rohe i te wā e utua ana e te PV te pākahiko, kia mau tonu ai te utu o ngā waka i te wā e motu ana te hiko. Me kimi ārai-motu me te aroturuki i te whakamarumaru mō tēnei āheinga, e ai ki te IEC 61851-23:2023, ā, he āhuatanga paerewa o ngā teihana utu BESS whakauru me ngā wae utu whakaora ohorere kua whakatauria he 65–200 kWh.

4. He aha ngā paerewa e pā ana ki te V2G me te utunga ā-rua i te tau 2026?

Ko ngā tuhinga whakahaere ko te ISO 15118-20:2022 (Plug & Charge me te whakawhitiwhitinga whakawhiti mana rua-ahu), ISO 15118-2 me te DIN 70121 (ngā kōtaha rua-ahu o mua), me te IEC 61851-23:2023 (te haumaru o ngā taputapu utu DC, tae atu ki te tautoko 1000V+, te whakamātautau-whaiaro IMD, me ngā whakaritenga haumaru taumata-āpiti mō te whakawhiti mana rua-ahu). Ka taka hoki ngā pae mana-teitei whakamatao-wai ki raro i ngā whakaritenga hononga me te porowhita whakamatao IEC 62196-3:2022.

5. Ka pakaru te pākahiko EV i te hononga waka-ki-te-whatunga (V2G)?

Kua hangaia te V2G hou kia pai mō te pākahiko: ka whakatakoto te rangatira o te waka (te kaiwhakahaere rānei o te waka) i te papa tukunga hiko — ko te tikanga he 20–30% te āhua o te utu — ā, ka herea te wā utu ki te hohonu o te tukunga hiko me te tatau huringa. E whakaatu ana ngā raraunga mara mai i ngā paearu V2G he iti noa te pānga o te huringa ā-rua-aronga, papaku, ki te whakahekenga o te pākahiko, ki te whakataurite ki te utu tere noa, ā, ko te utu pūtea mō ngā ratonga whatunga he nui ake i te ngaronga kaha piki haere.

6. Kia pēhea te roa o te wā e utua ai te haumitanga ki te penapena hiko pūngao rā?

I ngā mākete he nui ngā horapa utu me ngā utu tono i te wā pīki — te nuinga o Ūropi, Amerika Te Raki, me ētahi wāhanga o Āhia-Moananui — ko ngā pae utu PV-BESS whakauru ka eke ki te utu i roto i ngā tau 3-6, ā, ka tere ake ina whakaurua ngā moni whiwhi urupare tono, ratonga tāpiri rānei. Ka poto te utu i te mea ka piki ake te ōwehenga o te whakamahinga whaiaro PV, nā te mea ka whakakapia e te pūngao rā ngā hoko whatunga utu nui rawa atu i te wā pīki.

7. He aha te rahi o te BESS e hiahiatia ana e au mō tētahi pū whakakī tere?

Ko te ture rahi mō ngā pokapū arumoni he 40–60% o te kaha utu o ia rā, me te tere tukunga C o te 0.5C, iti iho rānei. Hei tauira, he pai te hononga o te pokapū 1,000 kWh/rā ki te BESS 400–600 kWh e tuku ana i te kaha tukunga 200–300 kW. Ka hipokina e te whānuitanga hua a MIDA te whānuitanga katoa — mai i ngā teihana whakaora 65–200 kWh me ngā pūnaha modular 215 kWh tae atu ki ngā pūnaha utu pūngao rā 800–2,000 kWh — kia taea ai te taurite i te taumata pākahiko ki ngā rohe tukunga o te papa me te hononga whatunga.

Whakamutunga

Ehara te whakaurunga o te penapena-rā-whakautu i te āhuatanga utu nui; koinei te tūāpapa whakahaere mō te utunga EV whai hua, tutuki i ngā whakaritenga, me te pakari i te tau 2026 me tua atu. Mā te whakakotahi i te hauhake PV tino whai hua, te parenga BESS, me te tahuritanga rua-aronga e hangai ana ki te SiC — me te whakawhitiwhiti kōrero V2G kua paerewahia i raro i te ISO 15118-20:2022 me te haumaru taputapu kua whakarārangihia i raro i te IEC 61851-23:2023 — ka whiwhi te pae whakauru mai i ngā awa moni e whā kaua ki te kotahi, ka ora i ngā huihuinga whatunga kaua ki te kati, ā, ka tukuna he nekehanga kore-tukunga mai i te pūtake ki te wira. Kei te noho tonu te hoahoa i tēnei rā hei raina hua kotahi, kua whakauruhia ki te wheketere: mai i ngā pūnaha rokiroki pūngao pākahiko me ngā waeine hiko rā MPPT i te taha whakaputa, mā roto i ngā waeine hiko AC-DC rua-aronga me ngā otinga utu V2G i te taha tahuri, ki ngā puranga utu ESS kua whakauruhia 60–400 kW me ngā pūnaha utu rā maha-megawatt i te taha whakatinanatanga. Ko ngā kaiwhakahaere e tohu ana i ngā pūnaha whakauru, whaimana, oti-paerewa, ko rātou inaianei te hunga e whakahaere ana i ngā rawa utu iti rawa te utu, te wā mahi nui rawa hoki i runga i te whatunga hiko mō te tekau tau e whai ake nei.

MIDA Power — te pana i ngā rohe o te utunga EV mā te whakamahi i ngā otinga hiko pūngao rā, rokiroki, me te hiko e rua ngā taha.
