He Aratohu a te Kaihoko mō ngā Kaitautoko DC 150kW: Te Hanganga Ā-Motu me ngā Tauira Moni Whiwhi

He Aratohu Hoko Hangarau Whānui mō ngā Teihana Utu Tere DC 150kW: Te Whakatere i ngā Hanganga Mana Modular, te Whakaurunga Whatunga, te Whakahaere Wera, ngā Pūnaha Tiaki Papa-maha, te Mahi Tahi OCPP, me ngā Tauira Moni Whiwhi Tauine mō ngā Hanganga EV Ātete-Ā-Mārama

Upoko 1: Kupu Whakataki: Te Pikinga Ake o te Utu Tere DC 150kW i te Ao EV

Kāore te nekehanga o te ao ki te nekeneke hiko e noho hei ia āhua noa iho, engari he pou matua o te kaupapa here āhuarangi o te ao me te rautaki ahumahi. I te mea e pāngia ana te aukati i ngā miihini mura ā-roto (ICE) i ngā mākete nui, me te tere haere o te tango a ngā kaihoko i ngā waka hiko (EV), kua eke te hiahia mō ngā hanganga utu pakari, pono, me te tere teitei ki tōna taumata teitei. I roto i te whānuitanga o ngā Taputapu Tuku Waka Hiko (EVSE), kua puta te utu tere DC 150kW hei "wāhi reka" nui mō ngā kaiwhakahaere arumoni, ngā kaiwhakahaere waka, me ngā kaiwhakarato ratonga tūmatanui.

He rerekē ki ngā rihi AC iti-mana e tika ana mō te whakamahinga i te pō, ki ngā rihi tino-teitei 350kW+ rānei e rāhuitia ana mō ngā waka papai me ngā taraka tawhiti, he taurite te whakaaro o te teihana 150kW. He tere ake te wā hurihanga i ngā waeine 50kW—he maha ngā wā ka whakakīia te 80% o te pākahiko EV hou i raro i te 30 meneti—me te pupuri tonu i te tapuwae me te whakaritenga whatunga hiko e taea te whakahaere. Nā tēnei ka waiho hei kaitono pai mō ngā teihana ratonga huarahi, ngā pokapū hokohoko, me ngā taiao "whakakī tere" o te tāone.

Heoi, ko te whiriwhiri i te rihi hiko 150kW tika ehara i te mea ko te whiriwhiri noa i tētahi waitohu mai i tētahi rārangi ingoa. Kei roto ko te māramatanga hohonu ki ngā hikohiko mana, ngā hangarau whakamatao, ngā kawa pūmanawa, me te whakatauira ōhanga. Mā te whiriwhiri hē i tētahi waeine ka nui ake ngā utu tiaki, ka maha ngā wā e kore ai e whakamahia, ka tere te tawhito i te whanaketanga o ngā hangarau pākahiko. He aratohu tēnei hei ruku hohonu ki te ao o te utu tere DC 150kW, e whakarato ana i te mōhiotanga e hiahiatia ana ki ngā kaihoko hei whakatere i ngā uauatanga o te whiriwhiri, te tāutanga, me te whakahaere mō te wā roa.

Ka tūhuratia e mātou te take he poutokomanawa te āhua o te hoahoa rihi hou, me pēhea te tiaki a te whakahaere wera matatau i te roanga o te ora o ngā taputapu, me pēhea te whakaurunga ki te Open Charge Point Protocol (OCPP) e whakarite ana kia noho ngāwari, kia taea hoki te mahi tahi i tō haumitanga. Hei tāpiri, ka tātarihia e mātou ngā tauira moni whiwhi e hanga ana i ngā teihana 150kW hei take pakihi whai hua, me te titiro ki tua atu i ngā hokonga kilowatt-haora noa ki ngā ratonga uara-tāpiri me te tautoko whatunga.

Upoko 2: Kōwhiringa Hangarau: Te Tautuhi i te Paepae 150kW mō te Whakamahinga Arumoni me te Whakamahinga ā-Iwi

I te aromatawai i tētahi rihi tere DC 150kW, ko te whakaaro hangarau tuatahi ko te kaha tuku tuturu i te atanga waka. Kāore i te rite te hanga o ngā rihi "150kW" katoa. Ko te mana kua whakatauria he mea nui noa iho i raro i ngā tikanga ngaohiko me te au motuhake. Mō te kaihoko, he mea nui te mārama ki te awhe ngaohiko—mai i te 200V ki te 1000V te tikanga. Ko ngā EV hou, pērā i ngā mea i hangaia i runga i ngā hoahoa 800V (hei tauira, Porsche Taycan, Hyundai IONIQ 5, Kia EV6), me whai rihi ka taea te pupuri i te ngaohiko teitei kia eke ki ō rātou tere utu tino pai. Ka uaua ki te rihi he iti ki te 500V te tuku 150kW ki ēnei waka hou, ka whakararu i te mahi.

Ko tētahi atu āhuatanga matua o te kōwhiringa ko te āheinga "utu tahi". He maha ngā teihana 150kW he hononga e rua (CCS1, CCS2, CHAdeMO rānei). Ka whakaatuhia he tiritiri hiko hihiri i roto i tētahi teihana kounga teitei. Hei tauira, ki te monohia ngā waka e rua, me taea e te teihana te tohatoha i te 75kW ki ia waka, ki te whakarite rānei i te waka he iti ake te āhua o te utu. Ko te mārama ki te whānui o tēnei tohatoha hiko—ahakoa he 10kW ngā pikinga, he 50/50 rānei ngā wehenga pumau—he rerekētanga hangarau nui.

He mea nui anō hoki te tapuwae ā-tinana me te whakatauranga o te whare. Mō ngā whakaurunga tāone nui he iti te wāhi, he pai ake te whakamahi i tētahi waeine kiato, katoa-i-te-kotahi. Heoi, mō ngā wāhi huarahi tere, he pai ake te whakamahi i tētahi pūnaha hoahoa-wehe (kei reira te hurihanga hiko ka puta i roto i tētahi kāpata mamao, ā, ka taunekeneke te kaiwhakamahi me tētahi tohatoha angiangi). Me manatoko anō hoki e ngā kaihoko ngā whakatauranga o te Parenga Whakauru (IP) me te Parenga Pānga (IK). Mō te whakamahinga tūmatanui o waho, ko te whakatauranga IP54, IP55 rānei me te whakatauranga IK10 mō te whare me te mata e kiia ana ko te paerewa ahumahi mō te pakari ki te huarere me te whakangaromanga.

Hei whakamutunga, kāore e taea te wareware i te atanga kaiwhakamahi (UI) me te whakaurunga utu. He hanganga e anga atu ana ki te marea te rihi 150kW. Me whakauru ki te kōwhiringa hangarau he mata pa kanapa teitei, ka taea te pānui i te rā, he tautoko reo maha, me te pūnga utu pakari e tautoko ana i te RFID, ngā kāri nama/nama, me ngā pēke pūkoro. I roto i te maha o ngā mana whakahaere, ko ngā ture "uru tuwhera" inaianei e whakahau ana me whakaae ngā rihi kāri nama me te kore e hiahiatia he taupānga motuhake, he mema rānei, ka waiho te whiriwhiri i ngā taputapu utu whakauru hei mea ture.

Upoko 3: Te Mana o te Whakarerekētanga: Te Hanganga, Te Tauine Whakarara, me te Taurite

I ngā rā tōmua o te utu tere DC, he maha ngā waeine i hangaia mā te whakamahi i ngā hoahoa "monolithic". Mēnā ka rahua tētahi wāhanga o roto, ka kore e whakamahia te utu katoa. I ēnei rā, kua neke te umanga ki te hoahoa whakarara modular, koinei pea te whanaketanga hangarau tino nui mō ngā utu 150kW. I roto i tēnei hoahoa, ka whakaputaina te putanga 150kW e tētahi puranga o ngā waeine hiko iti ake, ka taea te whakawhiti wera—ko te tikanga he 20kW, 30kW, 40kW rānei ia waeine.

E toru ngā painga o te āhua rerekē: te pono, te ngāwari o te mahi, me te āheinga tauine. Mai i te tirohanga pono, mēnā he rima ngā waeine 30kW o tētahi rihi hiko 150kW, ā, ka pakaru tētahi waeine, kāore te teihana e pōuri. Engari, ka uru ki te "aratau whakaheke", ka tukuna tonutia te 120kW o te hiko ki te kaiwhakamahi. Mā tēnei ka kore te taraiwa e mau, he mea nui tēnei mō te pupuri i te pai o te kiritaki me te ingoa pai o te pae.

Kua tino pai ake hoki te ngāwari o te mahi. Engari ko te tono i tētahi miihini tino tohunga ki te tātaritanga me te whakatika i ngā ara iahiko ā-roto uaua i te papaanga, ka taea e te tohunga hangarau te tautuhi noa i te waeine hapa ka whakawhiti ki tētahi mea hou i roto i ngā meneti. Ka whakaitihia e tēnei te Wā Tohatoha ki te Whakatika (MTTR) me te whakaiti i te taumahatanga o te penapena i ngā wāhanga e manawapa ana, nui. Mō ngā kaiwhakahaere nui, ko te tikanga o tēnei he iti ake ngā whakapaunga whakahaere (OPEX).

Hei whakamutunga, mā te momo hiko ka taea te whakarite i ngā mea kei te heke mai. Tērā pea ka tīmata te kaihoko me te whirihoranga 150kW engari ka tāutahia he kāpata ka taea te pupuri i ngā momo hiko tae atu ki te 200kW, 300kW rānei. I te tipu haere o te tono, me te āheinga o te whatunga hiko, ka taea e te kaiwhakahaere te mono noa i ētahi atu momo hiko hei whakanui ake i te kaha o te papaanga me te kore e hiahia ki te whakakapi i te teihana tūturu katoa, ki te keri rānei i ngā rua hou. He tino ātaahua tēnei tauira "utu-i-te-tipu" mō ngā kaipupuri moni kāore i te tino mōhio ki te tere o te whakamahi i te EV i roto i tō rātou rohe.

Upoko 4: Te Pūtahitanga o te Pūnaha Hiko: Te Arotautanga Whai Hua me ngā Rautaki Taurite Utaina

Ko te mohio o tētahi rihi tere DC 150kW ehara i te mea ko ōna wāhanga hiko mata anake, engari ko te pūmanawa matatau e whakarite ana i te hononga i waenga i ōna waeine hiko. I roto i tētahi pūnaha waeine, ko te kaiwhakahaere matua te "roro", e whakahaere ana i te tangohanga o te iahiko mai i ia waeine hei whakanui ake i te whai huatanga me te roa o te ora. Ka tutukihia tēnei mā roto i ngā rauropi taurite kawenga matatau e aroturuki ana i te hauora, te pāmahana, me te hītori whakamahinga o ia waeine takitahi i roto i te puranga.

He mea nui te arotau i te whai huatanga mō te oranga ōhanga o tētahi teihana utu. He maha ngā waeine hiko he pihi whai huatanga e eke ana ki te taumata teitei i tētahi kawenga motuhake—he maha i waenga i te 50% me te 80% o tō rātou kaha kua whakatauhia. Mena he 30kW anake te kaha e tukuna ana e tētahi rihi 150kW ki tētahi waka kua tata kī te pākahiko, he tino koretake te whakahaere i ngā waeine katoa i te 20% o te kawenga nā te mea he ngaronga whakawhiti pumau me te tango hiko āwhina. Engari, ka moe te kaiwhakahaere atamai i ngā waeine e whā, ā, ka whakahaere i tētahi waeine 30kW kotahi i tōna taumata whai huatanga teitei. Ka taea e tēnei mahi "aratau moe" te whakaora i ngā mano kilowatt-haora puta noa i te roanga o te oranga o tētahi rihi, ka pā tika ki te hua o te kaiwhakahaere.

Ka horapa atu hoki te taurite kawenga ki te whakahaere wera o ngā kōwae. I ngā wā whakahaere mana-teitei, ka whakaputahia e ngā kōwae he wera nui. Ka hurihia e tētahi pūnaha matatau te kawenga i waenga i ngā kōwae kia kore ai he waeine kotahi e wera tonu ana i ētahi atu. Mā te tohatoha ōrite i te "taumahatanga wera", ka ārai te pūnaha i te koroheketanga ā-rohe, ā, ka whakaroa i te Wā Tohatoha i waenganui i ngā Rahunga (MTBF) mō te puranga hiko katoa. Hei tāpiri, ka taea e ēnei pūnaha te kite i ngā tohu wawe o te hekenga o te kōwae—pērā i ngā ngaru hiko rerekē, te wera nui rānei mō tētahi kawenga—ā, ka tohu wawe i a rātou mō te tiaki i mua i te puta o tētahi rahunga.

Mō ngā wāhi tuku hiko maha, ka nui ake te uaua o te mahi tahi. Me tohatoha hihiri e te kāpata hiko pokapū e mahi ana i ngā turanga maha ana rauemi kōwae i runga i ngā ānau āhua-utu (SoC) rerekē o ngā waka hono. Mena kei roto tetahi waka i tana wāhanga "utu nui" ā, ka taea e ia te tango i te 150kW, ko tētahi atu kei roto i te wāhanga "whakaiti" e tango ana i te 20kW anake, me neke pai te pūnaha i ngā kōwae mai i tētahi putanga ki tētahi atu. Me whai tikanga whakawhitiwhiti tere-teitei tēnei (he maha ngā wā e hangai ana ki te pahi CAN, ki te Ethernet ahumahi rānei) i roto i te rihi hei whakarite kia puta ngā nekehanga hiko i roto i ngā mirihekona me te kore e whakararu i te wā utu, e whakaoho rānei i te kati haumaru taha-waka.

Upoko 5: Whakahaere Wera Matatau: Whakamatao Wai me te Hau Whakahau mō ngā Whakatika Mana-Tiketike

I te mea ka panaia ngā utu tere DC ki te awhe 150kW me tua atu, ka noho te whakahaere wera hei wero hangarau matua. Kāore e 100% te whai hua o te huri i te AC ngaohiko teitei mai i te whatunga ki te DC mō te pākahiko; ko te ngaronga pūngao tata ki te 4% ki te 7% ka puta katoa hei wera. I roto i te pūnaha 150kW, ko te tikanga o tēnei ko te whakahaere i te 10kW o te wera e marara ana—he rite ki ētahi whakamahana wāhi nui e rere ana i roto i tētahi pouaka whakarewa hiri. Ko te whakahaere i tēnei wera ka whakatau tika i te pono o te utu, te taumata haruru, me ngā whakaritenga tiaki.

Ko te whakamatao hau ā-kaha te tikanga tuku iho me te tikanga tino noa mō ngā waeine 150kW. Ka whakamahia e ia ngā pā hau ahumahi tere-teitei hei kukume i te hau taiao mā roto i ngā waeine hiko me te whakawhiti i ngā totohu wera. Ahakoa he iti te utu me te ngāwari ki te tiaki, he maha ngā ngoikoretanga o te whakamatao hau. Tuatahi, ka whakauruhia e ia ngā poke taiao—te puehu, te makuku, me te hau tote—ki roto i ngā hikohiko ā-roto tairongo, ka hiahiatia he tātari kounga teitei, he maha ngā wā ka hurihia. Tuarua, i te kaha teitei, ka tino haruru ngā pā hau, ka waiho hei raruraru i ngā wāhi noho, i ngā taiao hokohoko teitei rānei. Hei whakaiti i tēnei, ka whakamahia e ētahi kaihanga ngā pā hau "puku tere rerekē" ka piki ake i te wā e tika ana, engari kei te mau tonu te herenga matua.

Ko te whakamatao wai te "paerewa koura" mō ngā hikohiko mana kiato teitei, ahakoa he nui ake te kitea i roto i ngā rihi tere-tino 350kW+. Heoi, kei te tīmata ētahi hoahoa 150kW papai ki te whakamahi i ngā waeine whakamatao-wai, i te hangarau pereti-makariri rānei. I roto i ēnei pūnaha, ka tohatohahia he whakamatao (he ranunga wai-glycol te nuinga) mā roto i ngā waeine hiko, ka haria te wera ki tētahi pūwhakamahana mamao. Mā tēnei ka taea te hanga i tētahi āputa hiri katoa, ka tiaki i ngā hikohiko mai i ngā āhuatanga o te rangi, ā, ka whakaitihia te haruru. Mō ngā kaihoko i ngā āhuarangi tino kino—ahakoa he koraha tino wera, he takutai moana rānei he hau tote—ko te utu tuatahi teitei ake o tētahi pūnaha whakamatao-wai, he pūnaha ara-hau hiri rānei, he maha ngā wā ka tika mā te whakaiti i te tiaki me te roa o te ora o ngā taputapu.

Ko tētahi atu whakaaro nui mō te wera i te 150kW ko te taura utu tonu. Ko ngā taura paerewa kāore i te whakamataohia he mea here ki te 200 Amps nā te mea he nui te wera i roto i ngā kawe hiko parahi. Hei tuku i te 150kW ki te waka 400V, me pana e te pūnaha te 375 Amps. Me whakamahi he taura matotoru rawa, taumaha, he uaua ki te whakahaere, me whakamahi rānei i te taura wai-whakamatao. Ka whakamahia e te taura whakamatao he wai e rere ana hei pupuri i te kakau me te waea kia matao, kia taea ai te hanga i tētahi hoahoa angiangi ake, ergonomic ake ka taea te whakahaere i te 400A, i te 500A rānei. I te wā e whiriwhiri ana i tētahi rihi 150kW, me tirotiro e ngā kaihoko mēnā kei roto i te waeine ngā taura whakamatao, mēnā rānei kei te whakamahi i ngā aratau "whakatairanga" e tuku ana i te iahiko teitei mō ngā wā poto, ā, muri iho ka whai ake ko te whakawhāiti wera.

Upoko 6: Hononga Whatunga me te Kounga Mana: Ngā Hāmoni, Ngā Whakawhitiwhiti, me te Rokiroki Pūngao ā-Rohe

He kaupapa hangarau ā-iwi te tāutanga o tētahi taputapu utu hiko tere 150kW DC, he kaupapa hiko anō hoki. He nui te hiko e tangohia ana e tētahi waeine 150kW kotahi mai i te whatunga tohatoha ā-rohe—he maha ngā wā ka nui atu i te kotahi whare tari iti, i te tekau mā rua rānei o ngā whare. Me mahi tahi tēnei me te kamupene ratonga ā-rohe kia taea ai e te whatunga te whakahaere i ngā kawenga hiko ohorere, nui e pā ana ki te utu hiko tere.

He āwangawanga hangarau nui te kounga hiko mō ngā ratonga hiko. Ko ngā utu tere he kawenga kore-raina e whakamahi ana i te whakawhiti auau-teitei, ka taea te whakauru i ngā "hauora" ki roto i te whatunga. Ka taea e ēnei hauora te whakawerawera i roto i ngā whakawhiti hiko me te pokanoa ki ētahi atu taputapu tairongo i runga i te ara iahiko kotahi. Me whai Active Power Factor Correction (PFC) me te tātari matatau ngā utu kounga teitei 150kW hei pupuri i te Total Harmonic Distortion (THD) i raro i te 5%, me te tutuki i ngā paerewa pēnei i te IEEE 519. Me rapu ngā kaihoko i ngā tiwhikete e kī taurangi ana kāore te utu e "whakapoke" i te pūtake hiko ā-rohe, nā te mea ka kore pea ētahi ratonga e hono atu ki ngā waeine kāore he tātari tika.

He maha ngā wā ka hiahiatia he whakawhiti hiko motuhake mō te hanganga ā-tinana hei whakaheke i te hiko waenga-ngaohiko (hei tauira, 11kV, 33kV rānei) ki te 480V, 400V AC rānei e hiahiatia ana e te rihi hiko. Me whakarite te rahi o tēnei whakawhiti hiko, kaua mō te 150kW noa iho, engari mō te kawenga pūmanawa teitei me te whānui haere ā muri ake nei. Hei tāpiri, he mea nui te tawhiti i waenganui i te whakawhiti hiko me te rihi hiko; mā te whakamahi roa i te taura ngaohiko iti ka nui te hekenga o te ngaohiko me te ngaronga pūngao, ka whakaiti i te mana whai hua e tukuna ana ki te waka, ka piki ake hoki te pire hiko a te kaiwhakahaere.

I ngā rohe he ngoikore ngā whatunga hiko, he nui rānei ngā "utu tono" (he whiu mō te whakamahinga hiko teitei), kei te rongonui haere te rokiroki hiko ā-rohe. Mā te hono i tētahi rihi 150kW me tētahi Pūnaha Rokiroki Pūngao Pūhiko (BESS), ka taea e ngā kaiwhakahaere te "ārai" i te whatunga hiko. Ka āta utu te BESS mai i te whatunga hiko i ngā wā kore-pīki, kātahi ka tere te tuku hei tautoko i te tono 150kW ina monohia he waka. Ka taea e tēnei rautaki "heu pīki" te whakaiti i ngā utu whakahaere me te tuku i te utu tere i ngā wāhi he nui rawa te utu mō te whakapai ake i te whatunga hiko tika. Hei whakauru i tēnei ki te kōwhiringa hangarau me whai rihi me te hoahoa hononga-DC ka taea te tango ngāwari i ngā whakaurunga mai i te whatunga hiko me te pākahiko tūmau.

Upoko 7: Te Haumaru Tuatahi: Ngā Tikanga Tiaki Pūmārō me te Pūmanawa Maha-Papa

He mea tino nui te haumaru i roto i te utu hiko DC kaha-teitei, nā te mea ka mahi te utu hiko 150kW i ngā ngaohiko me ngā iahiko ka mate pea mēnā kāore e tika te whakahaere. He maha ngā paparanga tiaki kei roto i te teihana 150kW ngaio, mai i ngā hononga ā-tinana ki te pūmanawa whakahaere kapua. Kua hangaia ēnei tikanga hei tiaki i te kaiwhakamahi, te waka, te whatunga hiko, me te taputapu utu tonu mai i ngā hapa.

Ko te paparanga tuatahi ko te tiaki taputapu ā-tinana. Kei roto i tēnei ko ngā Pūrere Auaha Toenga (RCD) o te Momo B, ka taea te kite i ngā au turuturu AC me DC. Mēnā he hapa whenua, ka taea e ēnei taputapu te hinga i roto i ngā mirihekona, ka wehea te rihi mai i te pūtake hiko. Hei tāpiri, me whai pūrere tiaki ngaru (SPD) te rihi hei tiaki i ngā whiunga uira, i ngā whakawhiti whatunga rānei. I roto i te kāpata, me whai ia wae hiko i tana ake fiusi, i tana ake pakaru ara iahiko rānei hei ārai i te pakaru ā-rohe kei pakaru ki tētahi tūponotanga ahi nui ake. Kei roto i te taura utu tonu ngā pūoko pāmahana i roto i te pane hononga; mēnā ka wera rawa ngā pine nā te hononga ngoikore, nā te pāmahana taiao teitei rānei, ka whakaiti aunoa te pūnaha i te hiko, ka whakamutu rānei i te wā.

Ko te paparanga tuarua ko te haumaru e ahu mai ana i te whakawhitiwhiti kōrero. Ko te utu DC hou e whakawhirinaki ana ki ngā kawa ISO 15118, DIN 70121 rānei mō te rūrū ringa i waenga i te rihi me te waka. I mua i te tukunga o te kotahi watt o te hiko, ka whakahaerehia e ngā pūnaha e rua he whakamātautau-ā-ringa. Ka whakamōhio te waka i tōna hauora pākahiko, te ngaohiko mōrahi e whakaaetia ana, me ngā rohe o te iahiko tihi. Ka manatoko te rihi i tōna tūnga ā-roto me te ātete ārai. I muri i te whakaū a ngā taha e rua i te tūnga "haumaru ki te haere tonu" ka kati te whakapā. I te wā katoa o te utu, ka mau tonu tēnei manawa whakawhitiwhiti kōrero; ki te ngaro te hononga mō ngā mirihekona torutoru, ka tapahia tonutia te wā mō te haumaru.

Ko te paparanga tuatoru ko te aroturuki i te whakamarumaru. Ka mahi ngā rihi tere DC i roto i te whirihoranga "IT grid" (terra motuhake), arā, kāore ngā raina DC pai, kino rānei e hono ana ki te whenua. Ka ine tonu te Pūrere Aroturuki Whakamarumaru (IMD) i te ātete i waenga i te pahi DC me te anga. Mena ka heke te whakamarumaru i raro i tētahi paepae (e inehia ana i roto i te kiro-ohm) nā te urunga mai o te makuku, te kakahu rānei o te taura, ka whakaohohia e te IMD he whakaweto tonu. He mea nui tēnei hei ārai i ngā tūponotanga "pānga ngaohiko" ka pāngia pea te kaiwhakamahi e te ru mai i te anga whakarewa o te rihi.

Hei whakamutunga, ka whakaratohia e te parenga kua tautuhia e te pūmanawa he parenga koretake. Ka aroturukihia e te kaiwhakahaere matua ngā raraunga pūoko katoa—te pāmahana, te ngaohiko, te iahiko, me te tere o te pā—ki tētahi huinga o ngā kōpaki haumaru kua tautuhia. Mena ka neke tetahi tawhā ki waho o te rohe haumaru, ka taea e te pūmanawa te tīmata i tētahi whakaweto whakahaere. Hei tauira, ki te tino iti te heke o te ngaohiko whatunga (brownout), ka mutu marie te wā e te pūmanawa hei ārai i te kino ki ngā wāhanga whakauru o ngā waeine hiko. Kei roto hoki i ngā pūnaha matatau te "kitenga mura arc," e whakamahi ana i ngā pūoko mārama ki te kite i ngā arc hiko ā-roto me te whakaweto i te pakaru matua i mua i te tīmatanga o te ahi.

Upoko 8: Pūnaha Pūmanawa: OCPP 1.6J/2.0.1 Whakaurunga, Utu, me te Whakahaere Mamao

Ehara te taputapu utu tere 150kW DC i te taputapu takitahi; he taputapu whatunga me whakauru ki roto i tētahi pūnaha pūmanawa matatini. Ko te paerewa ahumahi mō tēnei whakawhitiwhiti kōrero ko te Open Charge Point Protocol (OCPP). I te wā e whiriwhiri ana i tētahi utu, ko te whakarite kia tutuki katoa ki te OCPP 1.6J (JSON) te whakaritenga iti rawa, ā, ko te tautoko mō te paerewa OCPP 2.0.1 hou ake e tino taunakitia ana hei whakarite mō ngā mea kei te heke mai.

Mā te OCPP ka taea e te rihi (te "pūwāhi utu") te kōrero ki tētahi tūmau matua (te "Pūnaha Whakahaere Teihana Utu" CSMS rānei). Mā tēnei whakaurunga ka taea ngā āhuatanga nui pēnei i te aroturuki mamao, ngā whakahōu pūmanawa, me te utu. Mō te kaihoko, ko te tikanga o te whakaurunga OCPP he "kāore he raka kaihoko." Mena kāore koe i te harikoa ki tō kaiwhakarato pūmanawa, ka taea e koe te huri ki tētahi atu me te kore e hiahia ki te whakakapi i ngā taputapu ā-tinana. He mea nui tēnei ngāwari mō te manawanui mahi mō te wā roa. Ka whakamanahia te whakatinanatanga OCPP o tētahi rihi "tuwhera" e te Open Charge Alliance (OCA), kia taea ai e ia te kōrero pai ki tētahi pito-muri e tutuki ana i ngā whakaritenga.

Mā tēnei paparanga pūmanawa ka whakahaerehia te utu me te whiwhi moni. Ka tukuna e te taputapu utu ngā raraunga ine ki te CSMS, ka tukatukahia ngā utu i runga i te kaha e pau ana (kWh), te wā e pau ana (meneti), te whakakotahitanga rānei o ngā mea e rua. I roto i te maha o ngā mākete, kei te noho hei rautaki matua te utu hihiri—te utu nui ake i ngā hāora pīki tono me te tuku hekenga ina nui te whakaputanga pūngao whakahou. Ka tautokohia hoki e ngā taputapu utu matatau 150kW te "Plug & Charge" (ISO 15118-2), ka tautuhi aunoa te waka i a ia anō ki te taputapu utu, ka whakakorea te hiahia mō ngā kāri RFID, ngā taupānga pūkoro rānei. Ka whakaratohia he wheako maeneene "rite ki a Tesla" mō te kaiwhakamahi, ā, ka whakanuia te tere o te teihana.

Ko te whakahaere mamao me te tātaritanga te wāhi e tino whai hua ai te pūnaha pūmanawa. He rawa nui te uara o te teihana 150kW, ā, ko te wā whakatā ka hua ake te ngaronga o te moni whiwhi. Ka taea e te CSMS pakari te whakarato i ngā whakatūpato wā-tūturu mō ngā hapa katoa, e āhei ai ngā kaiwhakahaere ki te whakatika i ngā take—pēnei i te pūmanawa e morearea ana, te pakaru rānei o te pūwāhi—mai i tawhiti, me te kore e tuku i tētahi tohunga hangarau ki te wāhi. Hei tāpiri, mā ngā whakahoutanga pūmanawa mamao ka taea e te rihi te noho hototahi ki ngā tauira EV hou i te wā e tukuna ana. I te whanaketanga o ngā matū pākahiko me ngā ānau utu, me whakahou ake te pūmanawa o te rihi hei whakapai ake i te mahi me te haumaru.

Upoko 9: Tātaritanga Ōhanga: Capex, Opex, me te Tauira Whiwhinga Moni 150kW (ROI)

Ko te haumi ki tētahi taputapu utu tere DC 150kW me mārama ki te āhua pūtea. Kua wehea te Utu Katoa o te Mana Pupuri (TCO) ki ngā Whakapaunga Pūtea (CAPEX) me ngā Whakapaunga Whakahaere (OPEX), ā, me whakamaheretia pai ia mea kia pai ai te hokinga mai o te haumi (ROI).

Kei roto i te CAPEX te utu hoko o te rihi hiko tonu, mō te waeine 150kW kounga teitei ka taea te eke mai i te $30,000 ki te $60,000 i runga i ngā āhuatanga me te kounga hanga. Heoi, ko te utu taputapu he 40% ki te 50% noa iho o te utu tāutanga katoa. Ko ngā mahi ā-iwi—te keri awa, ngā papa raima, me ngā pou tiaki—he mea nui pea, inā koa i ngā taiao tāone nui. Ko ngā whakahoutanga hiko, tae atu ki te whakawhiti hiko hou me te taputapu whakawhiti kaha-nui, ka taea te tāpiri i ngā tekau mano tāra ki te pire. Me whai whakaaro hoki ki ngā utu whakaaetanga me ngā utu hononga mai i te kamupene ratonga. Mō te tini o ngā kaihoko, he mea nui ngā tahua kāwanatanga me ngā whakatenatena taake hei whakakore i ēnei utu tīmatanga, e kapi ana i te 50% ki te 80% o te CAPEX i ngā rohe he whāinga hiko kaha.

Ko te OPEX te utu tonu mō te pupuri i te teihana kia rere. Ko te wāhanga nui rawa atu ko te utu hiko, e uru ana ki roto ehara i te hiko anake e pau ana engari ko ngā "utu tono". Ko ēnei utu ā-marama i runga i te kukume hiko teitei rawa (i roto i te kW) i tuhia ki te papaanga. Ka taea e te wā kotahi 150kW te whakaoho i te utu tono nui ka whakakore i te hua mai i ngā wā maha iti ake. Hei whakahaere i tēnei me whai pūmanawa utu atamai, rokiroki pākahiko ā-rohe rānei e ai ki te kōrero i roto i te Upoko 6. Ko ētahi atu tūemi OPEX ko te ohaurunga ā-marama mō te CSMS, te hononga waea pūkoro mō te utu, me ngā haerenga tiaki ā-tau. Ko te ture pai ko te whakarite tahua 3% ki te 5% o te utu taputapu mō te tiaki me ngā whakatikatika ā-tau.

Kei te whanake haere te tauira moni whiwhi mō te teihana 150kW i tua atu i ngā hoko pūngao noa. Ahakoa ko te "tawhē mō ia kWh" te kaiārahi matua, kei te whakawhānui ake ngā kaiwhakahaere angitu i ā rātou awa moni whiwhi. Ko ētahi e tuku ana i te utu "tere utu nui", e utu nui ake ai ngā kaihoko mō te urunga atu ki te rihi 150kW ki te whakaritea ki ngā waeine puhoi ake. Ko ētahi e whakamahi ana i te teihana utu hei "kaiārahi mate" hei akiaki i te haere o ngā waewae ki ngā wāhi hokohoko—e whakanui ake ana i te "wā noho" me te whakapaunga tuarua ki ngā wharekai, ki ngā toa rānei. Hei tāpiri, i te pakeketanga o te hangarau V2G (Waka-ki-te-Whatunga), ka taea e ngā teihana 150kW te whiwhi moni whiwhi mā te whakarato i te whakahaere auau me ētahi atu ratonga tāpiri ki te whatunga hiko. Hei tatau i te ROI, me matapae e ngā kaiwhakahaere ngā reiti whakamahinga—te ōrau o te rā e whakamahia ana te rihi. Ko te rihi 150kW me whai reiti whakamahinga o te 15% ki te 20% kia pakaru ai te utu i roto i te 3 ki te 5 tau, me te whakaaro he whānui te horapa i waenga i ngā utu hoko me te hoko hiko.

Upoko 10: Ngā Rautaki Tāutanga me ngā Mahi Whakahaere me te Tiaki mō te Wā Roa (O&M)

He haerenga uaua te whakawhiti mai i tētahi rawa kua hokona ki tētahi teihana utu tere DC 150kW e whakahaeretia ana, e hiahia ana ki te whakamahere tupato me te whakapau kaha mō te wā roa ki te tiaki. Ehara te tāutanga i te kaupapa "mono-ā-ringa"; he kaupapa hangarau maha-mātauranga. Me whai whakaaro te wāhanga whiriwhiri wāhi ki te urunga atu—kia taea ai e ngā EV me ngā waka wira-roa te neke ngāwari ki roto i te wāhi utu me te kore e aukati i te waka. Me whakaiti te takotoranga ā-tinana o te utu i te taumahatanga o te taura; ka ārahi te waeine kāore i te pai te whakanoho ki te tōia o ngā taura puta noa i te ara, ka pakaru wawe ngā pane o te whakamarumaru me ngā hononga.

He mea nui anō hoki ngā whakaaro mō te hangarau ā-iwi. Me hanga te turanga raima mō te waeine 150kW kia tautoko i te taumaha o te kāpata (ka neke atu i te 500kg mō ngā waeine modular) me te ātete ki ngā kawenga hau i ngā wāhi e kitea ana. Me whakarite te rahi o ngā awaawa o raro whenua mō ngā taura parahi, konumohe rānei he kaha teitei, me te aro nui ki ngā porowhita piko hei ārai i te kino o te whakamarumaru. I ngā āhuarangi makariri, me whai pea te aroturuki wera mō ngā awaawa, te turanga rānei, hei ārai i te hukapapa kei pakaru ngā hononga hiko. Ko te rama tētahi atu āhuatanga nui engari he maha ngā wā ka warewarehia; he haumaru ake te āhua o te teihana e mārama ana mō ngā kaiwhakamahi i te pō, ā, ka āwhina i ngā kāmera whakauru (mēnā kei reira) ki te hopu i ngā pikitia mārama hei ārai i te haumarutanga me te whakangaromanga.

Kia whakakahangia te teihana, ka huri te arotahi ki ngā Mahi Whakahaere me te Tiaki (O&M). Mā te rautaki O&M matatau ka wehea te wāhi whai hua mai i te nama. E toru ngā momo tiaki ka whakarōpūtia e mātou: te ārai, te whakatikatika, me te matapae. Ko te tiaki ārai ko te toro atu ki te wāhi kua whakaritea—ia ono marama te nuinga—ki te mahi i ngā mahi pēnei i te horoi, te whakakapi rānei i ngā tātari hau, te tirotiro i te taipana o ngā pito hiko (ka taea te wetekina i roto i te wā nā te huringa wera), me te tirotiro i ngā taura utu mō ngā pakaru, ngā motu rānei. Ka tūtohu hoki mātou kia "horoi hohonu" te whare i ia wā hei tango i te puehu me ngā poke e aukati ana i te marara o te wera.

Ko te tiaki whakatikatika te urupare ki tētahi rahunga tūturu. He mea nui te whai Whakaaetanga Taumata Ratonga (SLA) me tētahi kaiwhakatū hiko ā-rohe kia tika ai te aro atu ki ngā take nui i roto i ngā haora 24 ki te 48. Mō ngā rihi hiko 150kW, ko te tiaki whakatikatika he whakawhiti noa i tētahi waeine hiko, engari ka uru atu hoki ki te whakatika i tētahi mata pakaru, te whakakapi rānei i tētahi kakau utu kua pakaru. Ko te tiaki matapae te momo tino matatau, e whakamahi ana i ngā raraunga i hangaia e te rihi hei matapae i ngā rahunga. Mā te aroturuki i te pāmahana o roto o tētahi waeine hiko e pā ana ki tana kawenga, ka taea e te pūmanawa te matapae i tētahi rahunga pā e tata mai ana, i tētahi pūnga hiko rānei e heke ana. Mā tēnei ka taea te whakakapi i te wā o tētahi haerenga kua whakaritea, ka karohia he motumotu kāore i whakaritea me te ngaronga o te moni whiwhi me te whakawhirinaki o te kiritaki.

Upoko 11: Te Whakatutukitanga, Ngā Paerewa, me te Whakatūpato i te Anamata mō te Utu Megawatt

Ko te whakatere i te whenua o ngā paerewa o te ao me ngā ture ā-rohe tētahi o ngā āhuatanga tino uaua o te whiriwhiri i tētahi rihi tere DC 150kW. Ehara i te mea ko te haumaru anake te mea e tutuki ai ngā whakaritenga; engari ko te mahi tahi me te tiaki ture. I Amerika Te Raki, ko te tiwhikete UL (Underwriters Laboratories) te paerewa koura, inā koa ko te UL 2202 mō ngā taputapu utu DC me te UL 2231 mō ngā pūnaha tiaki kaimahi. I Ūropi me te maha atu o ngā rohe, he mea whakahau te tohu CE me te piri ki ngā paerewa IEC 61851 me te IEC 62196.

Haunga te haumaru hiko taketake, me whai whakaaro ngā kaihoko ki ngā paerewa ine. I roto i ngā mana whakahaere maha, pērā i a Tiamana me tana ture "Eichrecht", me whai mana ture te mita hiko i roto i te rihi hiko, me te kitea hoki e te kaihoko, me te whakarite kia utua tika rātou mō te mea i riro i a rātou. I te mea he maha atu ngā whenua e whakamahi ana i ngā ture tiaki kaihoko rite, ko te whiriwhiri i tētahi rihi hiko me te mita DC tino tika kua whai mana, he taahiraa nui ki te tiaki i tō haumitanga ā muri ake nei. Hei tāpiri, kei te huri te haumarutanga tukutuku hei arotahi ture. Ko ngā rihi hiko he wāhi whakauru ki te whatunga me te whatunga o te kaiwhakarato ratonga; me whakatinana e rātou te whakamunatanga pakari (TLS 1.2, teitei ake rānei), ngā tukanga whakaara haumaru, me ngā papaki haumarutanga auau hei tiaki i a rātou mai i te taumanutia me te takahi raraunga.

Ko te whakarite i ngā mea kei te heke mai ko te titiro whakamua ki te whakatupuranga hou o te hangarau EV. Ahakoa he "tere" te 150kW i tēnei wā, kei te anga whakamua te umanga ki te 350kW, tae atu ki ngā Pūnaha Utu Megawatt (MCS) mō ngā taraka taumaha. Ka whiriwhiri te kaihoko whakaaro whakamua i tētahi tūāpapa 150kW ka "ka taea te whakapai ake." Ko te tikanga pea tēnei he kāpata me ngā mokowā kau mō ētahi atu waeine hiko, he pūnaha rānei i hangaia mō te "hononga whakarara," ka taea te whakakotahi i ngā waeine 150kW e rua hei tuku 300kW ki tētahi waka kotahi mēnā e hiahiatia ana. Hei tāpiri, me tautoko te ISO 15118-20 (te putanga hou o te paerewa whakawhitiwhiti kōrero) hei whakahohe i ngā āhuatanga matatau pēnei i te utunga rua-aronga (V2G/V2H) me te whakaurunga whatunga matatau ake.

Ko tētahi atu āhuatanga o te tiaki i te heke mai ko te oranga tonutanga o te taiao. Ko ngā rauemi e whakamahia ana i roto i te hanganga o te rihi - te konumohe hangarua me te maitai peita, te momo whakamatao e whakamahia ana i roto i ngā pūnaha wai - ka nui ake te pānga ki ngā tohu "kakariki" o te teihana. Kei te whakauru kē ētahi kaiwhakahaere i ngā tuanui pūngao rā ki runga i ā rātou rihi 150kW. Ehara i te mea ka whakarato noa i te whakamarumaru me te tiaki ua mō ngā kaiwhakamahi engari ka whakaputa hoki i te pūngao ma ka taea te whāngai tika ki roto i te pahi DC o te rihi, ka whakaiti i ngā mate tuku me te whakapai ake i te whai huatanga whānui o te papa.

Upoko 12: Whakamutunga: Te Hanga Pūtea Rautaki ki te Hanganga DC 150kW

He whakatau maha-ahu te whiriwhiri i tētahi rihi tere DC 150kW e tū ana i te hononga o te hangarau hiko, te whakaurunga pūmanawa, me te rautaki pakihi. I roto i tēnei aratohu, kua tūhuratia e mātou ngā āhuatanga hangarau e wehewehe ana i tētahi teihana kounga teitei, pono mai i tētahi teihana whānui. Kua kite mātou ko te āhua rerekē te pūtake o te pono, ko te whakahaere wera matatau te kī ki te roa o te ora, ā, ko te tutuki i te OCPP te huarahi ki te ngāwari.

He kōwhiringa rautaki te paepae 150kW. He tere rawa hei whakatutuki i te hiahia o te taraiwa EV hou mō te "whakakī" tere, engari he iti ake te utu, he māmā ake hoki te whakatinana i ngā pūnaha 350kW tino tere. Mō te kaihoko, ko te angitu o tēnei haumitanga e whakawhirinaki ana ki te titiro ki tua atu i te utu hoko tuatahi. Ko te uara tūturu kei roto i te Utu Katoa o te Mana - te kaha o te rihi ki te pupuri i te wā mahi roa, te urutau ki ngā tauira waka hou, me te whakaputa moni whiwhi pumau mā te whakahaere hiko atamai me ngā ratonga uara-tāpiri.

I te whanaketanga tonu o te ao EV i te tere tere, ka pārekareka ngā whakataunga o nāianei mō te tekau tau neke atu rānei. Mā te whakatairanga i te haumaru, te whai huatanga, me te kaha ki te whakawhānui, me te mahi tahi me ngā kaihanga rongonui e whakarato ana i te tautoko O&M pakari, ka taea e ngā kaipupuri moni te hanga i tētahi whatunga utu e kore e tutuki noa i ngā hiahia o ngā taraiwa o nāianei engari e tū rite ana hoki mō ngā wero o āpōpō. He marathon te whakawhiti ki te nekeneke hiko, ehara i te oma tere, ā, ko te utu tere DC 150kW tētahi o ngā taputapu tino kaha i roto i ā mātou patu hei whakarite kia angitu te haerenga.

Tāpiritanga A: Rārangi Arowhai Hangarau mō te RFP Whakamahinga Tere DC 150kW (Tono mō te Tūtohinga)

Ina tukuna he Tono mō te Tūtohinga (RFP) mō ngā taputapu utu tere DC 150kW, he mea nui kia mārama koe ki ō whakaritenga hangarau kia whiwhi ai koe i ngā tono rite me te kounga teitei. Whakamahia te rārangi arowhai e whai ake nei hei tīmatanga:

• He mahere ara MCS kua tuhia e te kaihoko mō te utunga taumaha?

Aratohu mō te Kaute me te Kōwhiringa

Kaua tetahi tūemi RFP kotahi e whakatau i te kirimana. Whakatakotoria he taumaha e whakaata ana i tō tauira pakihi: ka paunatia e te kaiwhakahaere o te ara tere te wā mahi me te mahi i te rangi makariri; ka paunatia e te kaiwhakahaere o te waka te hohonutanga o te OCPP me ngā mahi whakahaere wāhanga tāpui; ka paunatia e te rangatira whenua hokohoko te whakaurunga utu me te ngāwari o te hoahoa. Tohua ia kaihoko 1-5 mō ia tūemi, whakareatia ki te taumaha, ka whakatairite i ngā tapeke. Ko te kaute neke atu i te 4.0 he tohu kei a koe he hoa mahi e tika ana kia whiriwhiria; ki te iti iho i te 4.0, ko te tikanga ka puta ake ngā "penapena" i muri mai hei wā kore mahi, hei waeatanga ratonga, hei rawa kua mau.

E rua ngā whakatūpato i te wā e whakatau ana i te utu: tuatahi, kaua e whakahua i tētahi kaihoko kāore e taea te whakaputa i tētahi nama tiwhikete, i tētahi pūrongo whakamātautau, i tētahi hoapā tohutoro rānei i roto i te kotahi rā pakihi — mā te taupatupatu tuhinga i te wāhanga RFP ka taea te tohu pono i te taupatupatu ratonga i muri i te whakatūnga. Tuarua, wehea te "pai ki te whai" mai i te "me whai" i mua i tō whakatauranga, kia kore ai he whakaaturanga hoko karismatik e whakanui i ō taumaha. Hei whakamutunga, pātai atu ki ia kaihoko kua tohua mō tā rātou mahere hua e rima tau te roa kua tuhia; ko te kaihoko kei roto i tana mahere mahi ko te NACS, V2G, me te MCS kei te haumi ki te heke mai kotahi e haumi ana koe.

Te Whakamutunga: Mai i te Rārangi Arowhai ki te Kirimana

Ka kati te aratohu i tēnei tāpiritanga i te ara kotahi e kati ai te tukanga hokohoko pai: me ngā taunakitanga. Ko te wāhanga 150kW te mea nui o te utu arumoni, ā, ko te rerekētanga i waenga i te rawa 10-tau me te nama 3-tau ka whakatauhia i roto i ngā tuhinga pēnei i tēnei RFP. Ko te hoahoanga tauira, ngā raraunga tutuki pono, te whakahaere mamao, me te mahere kaihoko e whakauru ana i te NACS me te V2G ngā tohu o te haumi rautaki kaua ki te hoko taonga. Ka taea te manatoko i ia tūemi o tēnei rārangi i roto i te rā whakamātautau me te wiki waea tohutoro - ki te whakaroa tetahi kaihoko ki tētahi o aua mea, kua tuhia kētia te whakautu.
