Hanganga Utu EV Ātete Hangarau: He Tātari Hangarau Whānui o te Whakahaere Wera, te Ahupūngao Ngaronga Hikohiko Mana, te Pūmautanga Whakawhitiwhiti Kōrero ISO 15118, me ngā Rautaki Tātaritanga Kapua Matatau mō ngā Taputapu Tuku Waka Hiko Mana-Tiketike

1. Kupu Whakataki: Te Whanaketanga o te Pono o te EVSE me te Hiahia Wā-Okioki

Kāore te whakawhiti ā-ao ki te nekenekehanga hiko e noho hei ia āhua noa iho, engari he pou matua o te kaupapa here ahumahi me te rautaki taiao. I te tere haere o te whakamahi i ngā waka hiko (EV), ka tūtaki ngā hanganga Taputapu Tuku Waka Hiko (EVSE) ki ngā tono kāore i kitea i mua. Kāore i rite ki ngā taputapu hiko kaihoko, ki ngā puku motuka ahumahi rānei, ka mahi ngā rihi EV—ina koa ko ngā Taringa Tere DC (DCFC) me ngā Taringa Tere Rawa (UFC)—i te wāhi e honoa ai te kaha teitei, ngā āhuatanga taiao rerekē, me ngā tikanga rūrū matihiko uaua.

He āhuatanga e pā kino ana ki ngā kaiwhakahaere me ngā kaiwhakamahi mutunga ko te āhuatanga "mutu", "wera rawa rānei". Ina mutu wawe te wā o te utu hiko, ina whakawhāitihia rānei te iahiko nā ngā herenga wera, he tohu tēnei i te korenga o te whakaurunga pūnaha. Ka whakaratohia e tēnei tuhinga he tātaritanga hangarau hohonu ki ngā pūtake o ēnei whakakorenga, mai i te ahupūngao taketake o te ngaronga o te mana haurua-waenga ki ngā āhuatanga uaua o ngā wā whakamutu whakawhitiwhiti kōrero ISO 15118 me ngā āhuatanga takahuri RCD. Mā te mārama ki ēnei momo korenga mā te tirohanga o te hikohiko mana me te hangarau wera, ka taea e tātou te hanga i ngā whatunga utu kaha ake, atamai ake, me te mahi teitei ake.

2. Te Ahupūngao o te Ngaronga Mana i roto i te Huringa Mana Auau-Tiketike

Kei te ngako o ia rihi hiko EV ko te waeine whakawhiti hiko, e huri ana i te AC whatunga ki te DC whakahaeretia e hiahiatia ana e te pākahiko o te waka. Ko te take "wera rawa" he kore e taea te whakahaere i te wera e puta mai ana i ngā ngaronga hiko i roto i tēnei tukanga whakawhiti. Hei whakatau i tēnei, me tatau tuatahi tātou ki hea e haere ana tēnei pūngao.

2.1. Ngā Ngaronga Arataki

Ka puta ngā ngaronga ara iahiko nā te ātete kore-kore o ngā taputapu haurua-ira (IGBT, MOSFET rānei) me ngā wāhanga kore-ātete ina kei roto i te āhua "kā". I roto i ngā MOSFET Silicon Carbide (SiC), e whakakapi haere ana i ngā IGBT Silicon tuku iho, ka tohuhia te ngaronga ara iahiko e te ātete-kā o te pūtake-wai ($R_{DS(on)}$). $$P_{cond} = I_{RMS}^2 \times R_{DS(on)}(T_j)$$ He mea nui, ko te $R_{DS(on)}$ e whakawhirinaki ana ki te pāmahana. I te pikinga o te pāmahana hononga ($T_j$), ka piki ake te ātete, ka hanga he porowhita urupare pai ka arahi pea ki te rerenga wera mena kāore e tino whakahaerea.

2.2. Ngā Ngaronga Whakawhiti

Ka puta ngā ngaronga whakawhiti i te wā e whakawhiti ana i waenga i ngā āhua ON me OFF. I roto i ēnei wā nanohekona, kāore te au me te ngaohiko e kore e rite ki te kore puta noa i te taputapu, ka puta te marara o te pūngao ($E_{on}$ me te $E_{off}$). $$P_{sw} = f_{sw} \times (E_{on} + E_{off})$$ I roto i ngā DCFC hou, ka akiaki ngā kaihoahoa kia teitei ake ngā auau whakawhiti ($f_{sw}$) hei whakaiti i te rahi o ngā wāhanga aukume (ngā inductors me ngā transformers). Heoi, ka whakanui tika ngā auau teitei ake i te kawenga wera, ka hiahiatia he arotautanga taraiwa kuaha matatau hei whakaiti i te taupatupatu o te ngaohiko me te au.

2.3. Ngā Ngaronga Aukume me ngā Ngaronga Parataiti

Haunga ngā haurua-ā-ira, he nui te wāhi o te whakawhiti auau-tiketike me ngā inductors ki te tahua wera. Ko ngā ngaronga matua (hysteresis me ngā au hurihuri) me ngā ngaronga parahi (pānga kiri me te pānga tata) i roto i ngā takai ka eke ki te 20% o te ngaronga katoa o te kōwae. I te mea ka piki ake ngā rihi ki te 350kW me tua atu, ka rite te hiranga o te whakahaere i ēnei ngaronga "koretake" ki ngā haurua-ā-ira tonu.

3. Te Ātete Wera me te Rerenga Wera: Te Pāngarau o te Werawera Nui

Ko te "wera rawa" he kupu whanaunga e tautuhia ana e te pāmahana whakahaere haumaru mōrahi o te wāhanga tino tairongo—ko te hononga haurua hiko, ko te hononga taura putanga DC rānei te tikanga.

3.1. Te Tauira Porowhita Wera

Ka taea e tātou te tātari i te rere o te wera mā te whakamahi i tētahi tauira hiko, ko te rerekētanga pāmahana he ngaohiko, ko te rere wera he iahiko, ā, ko te ātete wera he ātete hiko. Ko te ātete wera katoa ($\theta_{JA}$) mai i te hononga ki te taiao ko: $$\theta_{JA} = \theta_{JC} + \theta_{CH} + \theta_{HA}$$ Kei hea:

• Ko te ātete hononga-ki-te-pouaka (o roto i te pūrere) ko te $\theta_{JC}$.
• Ko te ātete o te pouaka-ki-te-heatsink ko te $\theta_{CH}$ (e whakahaeretia ana e Thermal Interface Materials – TIM).
• Ko te $\theta_{HA}$ he ātete whakamahana-ki-te-ātea (e whakahaerehia ana e te tikanga whakamatao).

3.2. Ngā Wāhi Wera ā-Rohe me te Pāmahana Papatipu

He maha ngā rihi ka mutu nā te mea he wāhi wera ā-rohe ka ngaro pea i ngā pūoko taiao o te pūnaha. Hei tauira, ka taea e te pūtu pakupaku i runga i te pae pahi DC te hanga i te ātete pa ki te awhe milliohm. I te 500A, ka whakaputahia e te ātete 1m$\Omega$ te 250W o te wera i roto i te rahinga iti, ka tere te heke o te whakamarumaru me te whakaoho i te kati wera i mua i te rehitatanga o te pūnaha whakamatao i te pikinga o te pāmahana hau putanga.

3.3. Arorau Whakaiti Wera

Ka whakatinanahia e ngā pūmana EVSE hou ngā herenga "ngāwari". Engari i te whakaweto pakari, ka whakaitihia e te pūnaha te iahiko mōrahi e whakaaetia ana ($I_{max}$) ina tata te pāmahana ki tētahi paepae. Mēnā ka nui ake te tere o te pikinga pāmahana ($dT/dt$) i tētahi pikinga, ka matapaetia e te pūnaha he rahunga, ā, ka whakamutua te wātū hei ārai i te kino o ngā taputapu. Ko te mārama ki tēnei ariā te mea nui ki te tautuhi he aha te take ka "mutu" ai te rihi i te āhua matapōkere i tētahi rā wera.

4. Ngā Hanganga Whakamatao Matatau: Whakamatao-Wai vs. Ngā Paipa Hau Motuhake

I te nekehanga o ngā taumata hiko mai i te 50kW ki te 400kW+, ka eke te whakamatao hau ā-pūmau tuku iho ki ōna rohe ā-tinana. Ko te tere rere o te hau e hiahiatia ana hei whakamarara i te 15-20kW o te wera para (i te 95% te whai huatanga) ka hiahiatia he pā hau nui, haruru me ngā tapuwae kāpata nui.

4.1. Te Hau Whakahau me ngā Pūwero Hau Motuhake

Ko tētahi auahatanga nui i roto i ngā rihi hau-whakamatao ko te hoahoa "paipa hau motuhake". I roto i ngā hoahoa tuku iho, ka kumea te hau mā roto i te kāpata hiko katoa, ka whakaatuhia ngā PCB tairongo ki te puehu, te haumākū, me te rehu tote. I roto i te hoahoa paipa motuhake, ka wehea ngā wāhanga whakaputa wera (ngā totohu wera, ngā inductors) i roto i tētahi hongere hiri. Mā tēnei ka ārai i ngā poke taiao kia tae atu ki te arorau whakahaere, me te tuku i te rere o te hau tere-teitei kia tangohia te wera mai i te atamira hiko. Heoi, ka waiho tonu te taura utu—he aukati nui—kia kore e whakamatao.

4.2. Ngā Pūnaha Utu Whakamatao-Wai

Mō te Utu Tere Rawa (UFC), kāore e hiahiatia ana te whakamatao wai. E rua ngā ara iahiko e whakamahia ana:

1. Whakamatao o te KōwaeHe pūnaha pereti makariri e tohatoha ana i te whakamatao (he ranunga wai me te ethylene glycol) i raro tonu i ngā kōwae hiko. He nui ake te kawe wera o te wai i te hau, e taea ai te iti ake o te $\theta_{HA}$.
2. Whakamatao TauraKa taumaha rawa, ka matotoru rawa hoki ngā taura mana-nui (>300A) mēnā ka whakawhirinaki ki te whakawhiti parahi anake. Ka whakamahia e ngā taura whakamatao-wai ngā ara iahiko parahi angiangi e karapotia ana e te koti whakamatao. Mā tēnei ka taea e te taura 400A te ngāwari rite tonu ki te taura paerewa 150A.

4.3. Ngā Āhuatanga me te Tiaki o te Whakawhiti Wera

Ka puta mai ngā momo rahunga hou i te whakamatao wai. Ka taea e ngā rahunga papu, ngā turuturu o te whakamatao, me ngā mirumiru hau i roto i te raina te arahi ki ngā hapa "wera nui" ohorere. Hei tāpiri, me pupuri kia ma te whakawhiti wera o waho (radiator). Mēnā kua kapi ngā tara o te radiator i ngā paru, ka ngoikore te kaha o te pūnaha ki te pana i te wera ki te āhuarangi, ka mutu te wā i te wā e piki ana ngā kawenga raumati.

5. Ngā Aromatawai Whatunga me te Tātaritanga Hapa Hiko

Ehara ngā rihi hiko EV i te kawenga takitahi; he whakararuraru nui ki te whatunga hiko. I tua atu, ko te kore pumau o te whatunga tetahi o ngā tino take o te "mutu" o ngā rihi, o te ripoata rānei i ngā hapa "Ngaohiko Whakauru Kāore i te Tika".

5.1. Ngā Hurihuri Ngaohiko me ngā Whakawhiti

Kāore i te tino tika te ngaohiko o te whatunga hiko AC i te 400V, 480V rānei. He maha ngā taiao ahumahi e pāngia ana e te hekenga o te ngaohiko (nā te tīmatanga nui o te motuka) me te ngaru nui (nā te uira, te whakawhiti whatunga rānei). Kei roto i ngā EVSE ko ngā ara iahiko Raka-Ngaohiko Iti (UVLO) me te Parenga-Ngaohiko Nui (OVP). Mena ka heke te whatunga mā te 15% mō ngā huringa maha, ka raru pea te wāhanga PFC (Power Factor Correction) ki te pupuri i te ngaohiko hononga DC, ka meinga he whakaweto ohorere hei tiaki i te kaitahuri DC-DC o raro.

5.2. Te Whakapōturitanga Harmonic Katoa (THD)

Ka whakamahia e te rihi hiko teitei te pana kore-raina, ka taea te wero i ngā haunga ki roto i te whatunga hiko. Mena he iti te "pakari o te whatunga" o te pae (he nui te aukati), ka taea e ēnei haunga te whakapohehe i te ngaru hiko ā-rohe. Ka taea e tēnei whakapohehe te whakararuraru i te kitenga kore-whiti i roto i te arorau whakahaere a te rihi hiko, ka arahi ki ngā hapa tukutahi me ngā "Whakakorenga Whakawhitiwhiti Kōrero" he hiko te pūtake.

5.3. Tauritekore o te Wāhanga

I roto i ngā pūnaha toru-wāhanga, ka nui rawa te au i roto i te ara iahiko kore (mēnā kei roto) nā te kore taurite o te ngaohiko i waenga i ngā wāhanga, ā, ka nui ake te ahotea wera i runga i ngā whakatikatika whakauru. Ka aroturukihia e ngā rihi matatau te whanaungatanga wāhanga-ki-wāhanga, ā, ka whakaroa, ka mutu rānei mēnā ka neke atu te kore taurite i te 3-5%, ka ārai i te kino o ngā wāhanga o roto.

6. Ngā Āhuatanga o te Pūrere Au Toenga (RCD) me te Whakakorenga Whakararuraru

He mea nui te haumaru i roto i te hoahoa EVSE, ā, ko te RCD te kaitiaki matua mō te ru hiko. Heoi anō, he pūtake auau hoki ia o ngā "Hē Pai" me ngā tūkinotanga whakararuraru.

6.1. Te Hiahia mō ngā RCD Momo B

Ka kitea e ngā RCD Momo A paerewa (e kitea whānuitia ana i roto i ngā whare) te turuturu o te hauhautanga me te turuturu o te hiko DC. Heoi, he nui ngā pākahiko me ngā kaitahuri DC-DC o ngā EV ka taea te whakaputa i ngā ia turuturu DC parakore. Mēnā ka puta he turuturu DC, ka "matapo" te RCD Momo A, ka kore e pakaru i te wā e puta ai he hapa AC tūturu. Nā tēnei take, me whakamahi ngā RCD Momo B mō ngā DCFC me ngā rihi AC teitei, ka taea te kite i ngā momo turuturu katoa tae atu ki te 1kHz me tua atu.

6.2. Ngā Au Aratau-Nui me te turuturu Auau-Tiketike

Ka huri ngā waeine hiko hou i te 20kHz ki te 100kHz. Ka pā tēnei $dv/dt$ teitei ki te kaha pirinoa i waenga i ngā wāhanga hiko me te whakamahana whenua, ka hangaia he iahiko "aratau-noa" auau-teitei. Ahakoa ehara ēnei i te " turuturu" morearea i roto i te tikanga tuku iho, ka taea e rātou te turaki i ngā RCD tairongo. Ko te rihi e "mutu" ana i te wā tonu ka tīmata te wāhanga piki-mana-teitei, he maha ngā wā ka pāngia e tēnei turuturu auau-teitei e nui ake ana i te paepae o te RCD.

6.3. Te Aroturukitanga Ārai (IMD)

I mua i te tīmatanga o te wā utu, ka whakahaerehia e te EVSE he whakamātautau ātete ārai i runga i te pahi DC. Mena kei raro iho i tētahi paepae motuhake te ārai i waenga i ngā raina DC+, DC- rānei me te Whenua (PE) (hei tauira, 500 $\Omega$/V), ka kore te rihi e tīmata. Ko te makuku i roto i te hononga utu, i te koti taura kua pakaru rānei, he take noa mō ēnei aukati "Hapa Ārai", inā koa i ngā āhuarangi ua, haumākū rānei.

7. ISO 15118 me te Uauatanga o ngā Tikanga Whakawhitiwhiti Kōrero Hou

He nui te ōrau o ngā whakararuraru wātū ehara i te hiko, i te wera rānei, engari he mamati. Ko te rūrū ringa i waenganui i te Kaiwhakahaere Whakawhitiwhiti Waka Hiko (EVCC) me te Kaiwhakahaere Whakawhitiwhiti Taputapu Tuku (SECC) he whiriwhiringa kawa nui.

7.1. PLC (Whakawhitiwhitinga Raina Hiko) me te Pono o te Tohu

Ka whakamahia e te ISO 15118-2 me te -20 te HomePlug Green PHY Power Line Communication. Ka whakarerekētia ngā raraunga ki te tohu Control Pilot (CP). Nā te mea kua honoa te waea CP ki ngā raina hiko au-rahi i roto i te taura utu, he tūmomo mōrearea nui te pokanoa hiko-hiko (EMI). Mena ka heke te ōwehenga tohu-ki-haruru (SNR) ki raro i tētahi taumata, ka "pau te wā" o te whakawhitiwhiti kōrero, ā, me whakamutu te utu i te wā mō te haumaru. Koia te take he mea nui te tiaki kounga teitei i roto i te taura utu.

7.2. SLAC (Te Āhuatanga Whakaiti Taumata Tohu)

I mua i te tīmatanga o te rūrū ringa taumata-teitei, me whakaū te EV me te EVSE kei te hono ā-tinana rāua mā te tukanga e kiia nei ko te SLAC. Mā tēnei ka ārai i te "kōrero whakawhiti" ina kōrero pōhēhē pea te motuka ki tētahi rihi tata. Mena ka rahua te tukanga SLAC nā te korenga o te hononga i roto i te hononga, i ngā koropiko whenua rānei, ka "noho noa te rihi i roto i te tūtatari" ka "kore rānei e tīmata."

7.3. Mono me te Utu (PnC) me ngā Ringaringa Tiwhikete

Ka whakaurua mai e te ISO 15118-2 a Plug and Charge, e whakamahi ana i ngā tiwhikete X.509 mō te whakamanatanga aunoa. Kei roto i tēnei he mekameka whakawhirinaki matatini e uru ana te OEM, te Kaiwhakahaere Teihana Utu (CSO), me te Kaiwhakarato Ratonga Nekeneke (MSP). Mena kua pau te wā, kua whakakorea, kua kore rānei e taea te toro atu ki tētahi hononga i roto i tēnei mekameka tiwhikete mā te pito-muri, ka mutu te wā utu me te hapa "Kua Rahua te Whakamanatanga", e rite ana ki te rahunga taputapu rihi ki te kaiwhakamahi.

8. Ngā Arorau Tātaritanga Whakauru me te Rorohiko Tapa

Hei neke atu i te whanonga "mutu ina hapa" noa iho, ka whakamahia e ngā EVSE hou ngā rauropi whakauru matatau hei tātaritanga i ngā take i te wā tonu.

8.1. Ngā Tātari Kalman mō te Hononga Pūoko

He maha ngā pūoko o te rihi: te pāmahana, te iahiko, te ngaohiko, me te haumākū. Heoi, ka taea e ngā pūoko te nekeneke, te pakaru rānei. Inaianei ka whakamahia e ngā pūnaha whakauru te tātari Kalman hei whakataurite i ngā raraunga. Hei tauira, mēnā ka piki tere te pāmahana o te pūoko whakamatao engari ka noho pumau tonu te pāmahana o te hononga waeine hiko, ka taea e te rauropi te tautuhi i te hapa o te pūoko kaua ki te āhuatanga ohorere wera, ka taea ai te aratau "ngoikore" kaua ki te whakaweto katoa.

8.2. Te Kimi Āwhata e Hangai ana ki te Ako Mīhini

He momo rahunga kino rawa te DC Arcing. Kāore e taea e ngā fiusi tuku iho te kite i te pewa raupapa i ngā wā katoa. Ka whakamahia e ngā kaiwhakahaere hou te Tukatuka Tohu Mamati (DSP) hei tātari i te "haruru" auau-teitei i runga i te pahi DC. Ka taea e ngā tauira ako mīhini, kua whakangungua ki ngā mano o ngā waitohu arcing, te kite i te tīmatanga o te pewa i roto i ngā mirihekona me te whakatuwhera i ngā whakapā i mua i te tīmatanga o te ahi.

8.3. Tātaritanga Huringa Ora Matapae

Mā te aroturuki i te maha o ngā huringa whakawhiti me ngā taumata ahotea wera ($T_j$ excursions), ka taea e te kaiwhakahaere whakauru te whakatau tata i te roanga o te oranga whai hua (RUL) e toe ana o ngā pūnga hiko me ngā haurua-ā-ira. Ka tukuna atu ēnei raraunga ki te kaiwhakahaere, ka taea ai te "Whakakapinga Matatau" - te whakakapi i tētahi kōwae i mua i te puta o te rahunga i waenganui o te wā.

9. Ngā Mahi Matatau e Hangai Ana ki te Kapua me te Tiaki Mahanga Mamati

Ko te paparanga whakamutunga o te pono ko te whakaurunga i waenga i te taputapu ā-tinana me te pūnaha whakahaere kapua, mā te OCPP (Open Charge Point Protocol) i te nuinga o te wā.

9.1. Arotautanga Pūmanawa Mamao

He maha ngā wā, he rerekē te whakatinanatanga o tētahi tauira EV hou e tukuna ana ki te mākete i te paerewa ISO 15118, ā, ka mutu te hototahi. Mā ngā rihi e hono ana ki te kapua ka taea e ngā kaihangarau te hopu i ngā "rangitaki putea" mai i te mara me te tuku i ngā papaki pūmanawa puta noa i te ao i roto i ngā haora hei whakatika i ēnei pepeke rūrū.

9.2. Ngā Māhanga Mamati mō te Matapae Wera

Mā te pupuri i tētahi "Mahanga Mamati" o ia teihana utu i roto i te kapua, ka taea e ngā kaiwhakahaere te whakahaere i ngā whakatauira. Mena ka tohuhia e te matapae huarere ā-rohe he ngaru wera, ka taea e te kaiwhakahaere kapua te whakaheke i te taupoki hiko mō ngā teihana motuhake kia mau tonu ai rātou i roto i ngā rohe wera haumaru, ka ārai i ngā kati ohorere e kino ai te whakawhirinaki o ngā kaiwhakamahi.

9.3. Te Taurite Utaina e Mōhio Ana ki te Whatunga

Ka taea e ngā tūāpapa kapua te whakauru atu ki ngā tohu ratonga hei whakahaere i te "Whakautu Hiahia." Mena kei raro te whatunga hiko i te ahotea, ka taea e te kapua te tohu ki tētahi rōpū rihi hiko kia whakaitihia tā rātou utu hiko mā te 10% ia tangata. Mā tēnei whakaiti tohatoha ka ārai i te kore pumau o te whatunga hiko ā-rohe me ngā hinganga RCD ka puta pea mena ka ngana te papa katoa ki te kukume i te hiko tino kaha i te wā kotahi.

10. Auahatanga Ārahi-Haupapa: SiC/GaN me te Anamata o te Whai Huatanga Wera

Ko te whakawhiti mai i te Silicon (Si) ki ngā haurua-ā-ira Whānui (WBG) pērā i te Silicon Carbide (SiC) me te Gallium Nitride (GaN) te taputapu tino nui hei whakaiti i te wera nui.

10.1. SiC me Si IGBT: He Whakataurite Wera

He iti ake ngā mate whakawhiti o ngā MOSFET Silicon Carbide ki te whakataurite ki ngā IGBT Silicon tuku iho. I roto i tētahi kōwae utu 30kW, mā te whakawhiti mai i te Si ki te SiC ka taea te whakaiti i te ngaronga mana katoa tae atu ki te 30%. Ko te tikanga tēnei he 30% te whakaiti i ngā whakaritenga o te pūnaha whakamatao. Heoi anō, ka taea e te SiC te mahi i ngā pāmahana hononga teitei ake (tae atu ki te 175°C, tae atu rānei ki te 200°C i roto i ngā tautuhinga taiwhanga), ka whakarato i te "tawhē haumaru wera" nui ake i mua i te hiahia o te pūnaha ki te whakawhāiti i te iahiko.

10.2. GaN mō ngā Utauta Ā-Roto me ngā Utauta AC

Ahakoa te mana o te SiC i te mākete hiko DC ngaohiko teitei, kei te hurihia e GaN te utu AC me ngā waeine hiko iti ake. Mā te nekehanga irahiko tino teitei o GaN ka taea te whakamahi i ngā auau whakawhiti teitei ake (i roto i te awhe MHz), e āhei ai te whakaitiiti i te utu katoa. Heoi, ko te kaha teitei ake o te GaN ka puta he wero rerenga wera ā-rohe e hiahia ana ki ngā papa uku matatau me te hangarau sintering hiriwa hei whakahaere.

10.3. Te Tauhokohoko Pono

He maha ngā wā ka puta mai te mahi teitei ake me ngā momo rahunga hou. He tairongo ngā MOSFET SiC ki te "Arotautanga o te Gate Oxide" me te "Pakari Poto-Porotaka." Me tino tere te arai tiaki o te rihi e whakamahi ana i te SiC (ka urupare i raro i te 2 maikorohekona) hei ārai i te rahunga kino i te wā o te hapa whatunga whakawhiti. Mena he tairongo rawa ēnei arai tiaki, ka taea e rātou te arahi ki ngā take "mutu" i hangaia ai rātou hei ārai—he wero arotau hangarau tawhito.

11. Te Pūtaiao Rauemi o ngā Hononga me ngā Huinga Taura: Te Hononga Whakamutunga

Ko te wāhi ngoikore o te mekameka wera ko te hononga ā-tinana i waenga i te rihi hiko me te motuka.

11.1. Ātete Pa me te Whakakikorua Hiriwa

E rau ngā huringa taumau o ngā pine i roto i te hononga CCS, MCS rānei (Megawatt Charging System). I roto i te wā, ka memeha haere te whakakikorua hiriwa o ngā pine, ka piki ake te ātete pa ($R_c$). Ahakoa he iti noa te pikinga o te ātete—mai i te 0.1m$\Omega$ ki te 0.5m$\Omega$—ka taea te whakanui ake i te pāmahana nui i te 400A ($P = I^2 R$). Kei roto i ngā hononga hou ngā whakamahana kua whakauruhia ki roto i te kakau e whakaoho ana i te whakahekenga mana mena ka neke ake te pāmahana o te hononga i te 90°C.

11.2. Te Pānga o te Whakamārama ki te Taiao

Ka pāngia ngā hononga e te ua, te hukarere, te tote, me te puehu. Ka taea e te waikura o ngā pine, te noho mai rānei o te makuku te hanga i tētahi "ara turuturu" ka whakanui ake rānei i te ātete. He mea nui te tiaki auau, tae atu ki te horoi ki ngā kaihoroi whakapā motuhake me te tirotiro mēnā he hē te tūnga o te pine, hei ārai i te hapa "Te Wera o te Hononga" e pāngia ana e te maha o ngā teihana utu tūmatanui.

11.3. Te Ora o te Whakapūmau Taura me te Ngenge ā-roto

He taumaha ngā taura utu, ā, he maha ngā wā ka taka, ka takahia rānei e ngā waka. Ka taea e te ngenge o roto o ngā aho parahi te whakanui ake i te ātete o te taura i roto i te wā. Ahakoa he pai te mahi a ngā taura wai-whakamatao, ka ngāwari ki ngā piko o roto e aukati ana i te rere o te wai whakamatao. Inaianei ka inehia e ngā pūnaha aroturuki matatau te "Hekenga Pēhanga" puta noa i te ara iahiko whakamatao kia kitea ai ēnei piko i mua i te whakaweto i te wera.

12. V2G (Waka-ki-Whatunga) me ngā Wero Wera Hou

Mā te hangarau Waka-ki-Whatunga (V2G) ka hurihia te EV hei pākahiko pūkoro mō te whatunga hiko. Heoi, mā te rere o te hiko e rua-ahu ka puta he ahotea wera hou.

12.1. Te ahotea o te waeine hiko rua-ahunga

I roto i te rihi paerewa, he kotahi te ahunga o te rere o te hiko. I roto i te V2G, me mahi ngā kōwae hiko hei kaitahuri me hei whakatikatika. Ka whakanuia e tēnei te katoa o ngā hāora mahi o ngā semiconductors me ngā capacitors, ka tere ake te tawhito o te wera. Me hoahoa te pūnaha whakahaere wera mō te mahi 24/7 kaua mō ngā huringa utu wā poto noa iho.

12.2. Tukutahitanga Whatunga i te wā V2G

Ina tukuna te hiko ki te whatunga hiko, me tino rite te tukunga o te ngaohiko me te auau ki te taputapu hiko. Ko ngā rerekētanga whatunga hiko i mua he "haruru" noa iho, kua noho hei āhuatanga pumau nui. Mā te nekehanga ohorere o te auau whatunga ka "kore tukutahi" te kaitahuri V2G ka whati, ka mutu te tukanga tukunga hei ārai i te kino o te whatunga hiko.

13. He Rangahau Take Ruku Hōhonu: Te Tātari i ngā Tūnga Wā-poto i roto i te Pokapū Mana-Nui o te Takutai Moana

Hei whakamārama i ēnei ariā, me tirotiro tātou i tētahi tauira o te ao tūturu o tētahi pokapū utu tere rawa 10-wae kei roto i te taiao takutai.

13.1. Te Tohumate

I pāngia te pokapū e ngā hapa "Whakamutu Whakawhitiwhiti Kōrero" me te "Hapa Whakamarumaru" i te nuinga o te wā, inā koa i te ahiahi me te atatu. I te awatea, i mahi noa ngā rihi hiko ahakoa he nui ngā kawenga.

13.2. Te Tirotirohanga

I whakapae tuatahi ngā tohunga hangarau i te puranga pūmanawa ISO 15118. Heoi, kāore i whakaatuhia e ngā rangitaki mōkihi he hapa pūmanawa ōrite. Kāore i whakaatuhia e ngā kāmera wera he wāhi wera i runga i ngā waeine hiko.

13.3. Te Pūtake: Te Kohu Tote me te Makuku

I neke te rangahau ki ngā āhuatanga taiao. He nui te tote i roto i te hau takutai. I te pō, ka heke te pāmahana, ka hua ake he hauhautanga i roto i ngā wāhanga kāore i hiritia o te kāpata. Nā te makuku kapi i te tote i hanga he ara kawe hiko puta noa i te ara iahiko whakahaere (CP), ka whakapohehe i te tohu PLC, ka puta ai he wā mutu whakawhitiwhiti kōrero. I tua atu, nā te makuku i whakaiti te ātete whakamarumaru o te pahi DC, ka whakaoho i te IMD (Insulation Monitoring Device).

13.4. Te Otinga

E rua ngā taahiraa i roto i te otinga:

1. Te whakapai ake i te kāpata ki tētahi hoahoa paipa hau motuhake kua whakatauria ki te IP55 me tētahi pūnaha whakamaroke hau.
2. Te paninga i tētahi paninga waipēhi motuhake ki ngā pine CP me ngā papa whakawhitiwhiti kōrero ā-roto.

I muri i ēnei whakarerekētanga, i whakaitihia ngā "mutu wā poto" mā te 98%.

14. Te Haumarutanga Ipurangi me ōna Pānga ki te Pono o te Pūnaha

I tēnei ao hou, kāore pea te "mutu" o te rihi e tohu i te korenga o te ahupūngao, engari he angitu o te haumarutanga.

14.1. Te Whakakorenga o te Ratonga (DoS) i te Tauranga Utu

Tērā pea ka ngana tētahi taputapu kino kua monohia ki te tauranga utu ki te whakakī i te SECC ki ngā mōkihi ISO 15118 kua hē te hanga. Hei tiaki i te whatunga me te waka, ka whakamutua te hononga e te pareārai ahi o te utu. Ko te wehewehe i waenga i te "taura kino" me te "whakaeke ipurangi" he arotahi nui o ngā rangahau tātaritanga o ēnei rā.

14.2. Te Whakaara Haumaru me te Pūmautanga Pūmanawa

Ki te kitea e te rihi kua raweketia tana pūmanawa (mā te korenga o te tirotiro Whakaara Haumaru), ka uru ki te āhua "Raka". Mā tēnei ka ārai i te whakamahinga o te rihi hei kuwaha hei whakaeke i te whatunga ā-rohe, engari ka hua ake he teihana "mate" mō te kaiwhakamahi.

15. Whakamutunga: Te anga atu ki te 99.99% Wā Mahi i roto i te Hanganga EV

Ko te whakaoti rapanga "Kei te mutu tonu, kei te wera rawa rānei te utu hiko waka rererangi" me whai huarahi hangarau whānui e hono ana i te āputa i waenga i te hikohiko mana, te pūtaiao wera, me te whakawhitiwhiti kōrero matihiko.

I a tātou e anga whakamua ana ki ngā Pūnaha Utu Megawatt (MCS) mō ngā taraka taumaha me ngā whatunga ā-ao mō ngā waka pāhihi, kāore he manawanui mō te rahunga. Me awhi tātou i:

• Whakahaere Wera MaamaaTe neke atu i te whakamatao tauhohe ki te whakahaere matapae, e whakahaerehia ana e te mahanga-matihiko.
• Whakawhitiwhiti Kōrero PakariTe whakapakeke i ngā puranga PLC me te ISO 15118 ki ngā tūmomo mōrearea EMI me te ipurangi.
• Ngā Rauemi MatatauTe whakamahi i te SiC me ngā hononga whakamatao-wai hei pana i ngā rohe o te mātotorutanga mana.

Ko te āmua o te kawe waka e whakawhirinaki ana ki te pono o te mono. Mā te mōhio ki ngā take noa o te pakaru o ēnei rā, ka hangaia e tātou te whatunga pūngao pakari o āpōpō.

16. Te Whakatauira Pāngarau Taipitopito o te Whakamarara Wera me te Ahumahi Wai

Hei whakaoti rapanga i te wera nui, me whakawhirinaki ngā kaihangarau ki ngā tauira pāngarau pakari e neke atu ana i ngā whatunga ātete wera noa iho.

16.1. Ngā Aromatawai Wai Rorohiko (CFD) i roto i te Hoahoa Kāpata

I roto i tētahi teihana utu hiko-teitei, he onge te rere o te hau kia rite ki te raina. Mā te pōrearea, te hekenga o te pēhanga puta noa i ngā tātari, me ngā putunga hau e noho pūmau ana ka taea te hanga i ngā "wāhi wera" kāore e kitea e ngā tauira wera iti-taumira. Mā te whakatauira CFD ka taea e ngā kaihoahoa te whakaatu i te mara tere tere $\vec{v}(x,y,z)$ me te pikinga pāmahana $\nabla T$. Mā te whakaoti i ngā whārite Navier-Stokes: $$\rho (\frac{\partial \vec{v}}{\partial t} + \vec{v} \cdot \nabla \vec{v}) = -\nabla p + \mu \nabla^2 \vec{v} + \vec{f}$$ ka taea e ngā kaihangarau te arotau i te whakatakotoranga o ngā parepare me ngā pā kia mōhio ai ka whiwhi ia waeine hiko i te wāhi ōrite o te kaha whakamatao.

16.2. Ngā Tauwehenga Whakawhiti Wera i roto i ngā Pereti Matao Whakamatao-Wai

Mō te whakamatao wai, ko te whai huatanga ka whakahaerea e te tau Nusselt ($Nu$), e hono ana i te whakawhiti wera ā-waka ki te whakawhiti wera kawe. I roto i ngā hongere moroiti o te pereti makariri SiC, ko te whāinga he whakanui ake i te tauwehenga whakawhiti wera ($h$) me te whakaiti i te mana papu e hiahiatia ana. $$h = \frac{Nu \cdot k}{D_h}$$ Ko $k$ te kawe wera o te wai, ā, ko $D_h$ te diameter waipēhi. Ka whakanui ake ngā pereti makariri "pin-fin" "micro-groove" hou i te horahanga mata, engari ka ngāwari ki te aukati mēnā kāore i te tātarihia tika te waipēhi, ka arahi ki ngā "aukati" kua whakaahuatia i mua ake nei.

16.3. Tātaritanga Wera Poto mō ngā Ara Whakautu Tere

Ehara te wā utu i te mea pumau. Ina tīmata te utu i tētahi Porsche Taycan, i tētahi Tesla Model S Plaid rānei, ka taea e te hiko te piki ake mai i te 0 ki te 250kW i roto i ngā hēkona. Ka puta he "oho wera" ki ngā semiconductors. Ka mahi te papatipu wera o te heatsink hei tātari iti-haere, engari ka taea e te pāmahana hononga ($T_j$) te piki tere tonu. Me whakaoti ngā whārite rerekē e whakaahua ana i tēnei whanonga whakawhiti i te wā tūturu e te kaiwhakahaere kia taea ai te whakahaere i te "Tepe o nāianei" i runga i te hihiri.

17. Rukuhia Hōhonu ki te ISO 15118-20: Te Anamata o te Whakawhitiwhiti Kōrero

Mā te whakawhiti mai i te ISO 15118-2 tawhito ki te paerewa ISO 15118-20 hou (te "Dash 20") ka puta mai ngā āhuatanga hou, engari me ētahi atu uauatanga hou ka arahi pea ki ngā rahunga o te wātū.

17.1. Tautoko mō te Megawatt Charging me te V2X

Kua hangaia te ISO 15118-20 hei whakahaere i ngā iahiko nui o te Pūnaha Utu Megawatt (MCS). Kei roto ko ngā āhuatanga haumarutanga whakarei ake (TLS 1.3) me te tautoko taketake mō te rere hiko e rua-ahu. Heoi, ko te pikinga o te utu haumarutanga te tikanga ka roa ake te rūrū ringa. Mena he ngoikore te pūnaha 12V o te motuka, he nui rānei te whakaroa i roto i te pito-muri pūkoro, ka taea e te "Tatūnga Wāhanga" te mutu, ka arahi ki te ahuatanga "kāore i taea te tīmata".

17.2. Aratau Mana Hihiri me te Mana Whakarite

I ngā putanga tawhito, ko te motuka te tikanga e whakatau ana i te āhua utu. I te -20, ka taea e te rihi te whai wāhi nui ake i roto i te "Mana Hihiri." Mā tēnei ka taea te whakahaere kawenga taipitopito ake engari me whai hononga raraunga tino tika. Ka taea e te "mōkihi kua taka" i te -20 te whakararuraru nui ake i ngā putanga tawhito, me whai waehere whakahaere hapa pakari ake i roto i te SECC.

17.3. Whakaurunga Utu Ahokore

Ka hipokina hoki e te ISO 15118-20 te utunga ahokore (whakauru). I konei, ka taea e te "aukati whakawhitiwhiti kōrero" te ā-tinana—ki te kore te motuka e tino hono ki te papa, ka heke te kaha o te tohu o te hononga whakawhitiwhiti tuarua (he maha ngā wā he mea motuhake, he mea hangai rānei ki te NFC), ka mutu te whakawhiti hiko mō te haumaru.

18. Te Tūranga o te Matauranga Horihori i roto i ngā Tātaritanga Aunoa me te Whakaora-ā-Iho

E kore te whakatupuranga hou o ngā rihi hiko e "pūrongo" noa i ngā hapa; ka "whakaoti" hoki e rātou.

18.1. Te Kite i ngā Āhuatanga Kāore i te Tika mā roto i ngā Whatunga Io Auau (RNN)

Mā te tātari i ngā raraunga raupapa-wā o te ngaohiko, te iahiko, me te pāmahana, ka taea e te RNN te kite i ngā tohu "i mua i te rahunga". Hei tauira, ko te tohu ngaohiko haruru iti pea e tohu ana i ngā wāhanga tōmua o te rahunga o te pūnga. Ka taea e te AI te tohu ki te kaiwhakahaere kia whakarite i te tiaki.i mua ika rahua te waeine, ā, he pai tonu te wā mahi.

18.2. Te Ako Whakakaha mō te Whakahaere Wera

He pūmau ngā pūmana PID (Proportional-Integral-Derivative) tuku iho. Ka taea e te pūmana wera e hangai ana ki te RL te "ako" i ngā āhuatanga wera motuhake o te taiao o te teihana. Tērā pea ka ako ia i te 2 i te ahiahi o te Tūrei, ka pā te rā ki te kāpata i tētahi koki motuhake, me piki ake te tere o te pā hau mā te 10% i mua i te rehitatanga o te pikinga pāmahana e ngā pūoko. Ka ārai tēnei "whakamatao tere" i te aukati wera e aukati ana i ngā wā utu.

18.3. Tātaritanga Pūtake Aunoa (RCA)

Ina mutu te utu hiko, ka taea e te kapua AI te mahi i tētahi RCA inamata. Ka taea e ia te whakawhiti i te waehere hapa ki te VIN o te waka, ngā āhuatanga whatunga ā-rohe, me te hītori ratonga o te teihana. Engari i te "Hapa Whakawhitiwhiti Kōrero" whānui, ka whiwhi te tohunga hangarau i tētahi tohutohu motuhake: "Whakakapia te taura tiaki CP, 85% te tūponotanga o te pirau o te kohu tote."

19. Te Whakamahere Hanganga me te Kōwhiringa Pae mō te Ātete ki te Wera

Ko te pono o te rihi hiko ka whakatauhia i mua i te tāutanga.

19.1. Te Pānga o te "Moutere Wera" i roto i ngā Whakatakotoranga Tāone

Ko ngā taputapu utu hiko e whakauruhia ana ki ngā papa waka uku i roto i ngā tāone kikī ka pāngia e te pāmahana teitei ake nā te pānga o te moutere wera. Me whakaiti te taumaha o ngā taputapu e ngā kaihoahoa, me haumi rānei ki te whakamatao pai ake (pēnei i te whakamatao wai) mō ēnei wāhi. Ko te taputapu utu hiko e mahi pai ana i roto i te karāti hauhautanga o te tāone, tera pea ka pakaru i ia rā i roto i te papa raima o te tāone e wera ana i te rā.

19.2. Te Pakari o te Whatunga me te Tata o te Whakawhitiwhiti

He huarahi kino te tāuta i tētahi rihi hiko kaha-nui ki te "pito o te raina" o tētahi whatunga hiko tuawhenua. Ko te ātete teitei o ngā taura roa ka arahi ki ngā hekenga nui o te ngaohiko ina piki ake te rihi hiko. Me whakarite e ngā kaiwhakamahere papaanga te tata ki te teihana hiko iti, me haumi rānei ki te rokiroki hiko ā-rohe (ngā ārai pākahiko) hei "whakapakari" i te whatunga hiko me te ārai i ngā aukati e pā ana ki te ngaohiko.

19.3. Te Aronga ā-Tinana me te Ātaahua

Mā te ārai i te hihi tika o te rā, ka taea e te tuanui māmā te whakaiti i te taumahatanga wera o te kāpata utu hiko tae atu ki te 20%. Hei tāpiri, mā te whakatakoto i ngā putanga hau kia matara atu i ngā hau puehu, i te rehu tote rānei, ka roa ake te ora o ngā tātari o roto, ā, ka ārai i te "wera nui" e puta mai ana i ngā ara manawa kua purua.

20. Aratohu Whakatau Rapanga Whānui me te Ripanga Whakarāpopototanga

Hei whakamutunga i tēnei ruku hohonu, ka whakaratohia e mātou he whakarāpopototanga o ngā momo rahunga e tino kitea ana me ā rātou otinga hangarau.

Mā te aro atu ki ēnei take i ngā wāhanga hoahoa, tāutanga, me te whakahaere, ka taea e te umanga te whakarite kia kore rawa te oati mō te nekenekehanga hiko e takahia e te "whakamutu" o te rihi hiko.

21. Ngā Paerewa ā-Ao me te Whenua Whakahaere mō te Pono o te EVSE

I te pakeketanga o te umanga, kei te whakauru mai ngā kāwanatanga me ngā whakahaere o te ao ki te whakahau i ngā paerewa mō te wā mahi me te pono, ā, koinei anō te take e akiaki ai i ngā whakaritenga hangarau mō te whakahaere wera me te tātaritanga.

21.1. Te Tātai NEVI me ngā Mana Whakahaere Wā-Okioki

I te Hononga o Amerika, e whakahau ana te kaupapa Hanganga Waka Hiko ā-Motu (NEVI) kia 97% te wā mahi mō ngā rihi e utua ana e te kāwanatanga ā-motu. Ko te "Wā Mahi" he mea tino mārama te whakamāramatanga—ko te rihi e mau ana engari kua whakaitihia ki te 10kW nā te wera nui ka kiia he "kore" mō ngā kaupapa o ēnei ture. Kei te akiaki tēnei i ngā kaiwhakahaere ki te neke atu i ngā waeine iti te utu, he hau-whakamatao ki ngā pūnaha pakari ake, he wai-whakamatao, he kapua-aroturuki.

21.2. AFIR i te Kotahitanga o Ūropi

Ko te Ture Hanganga Hinu Rerekē (AFIR) i roto i te EU e whakanui ana i te māramatanga me te mahi tahi o ngā utu. Ko te pono he wāhanga matua o te "Wheako Kaiwhakamahi." I raro i te AFIR, me whakarato e ngā taputapu utu ngā raraunga tūnga wā-tūturu ki ngā Pūwāhi Uru ā-Motu (NAP). Ka tohua e ēnei pūnaha he taputapu utu e mutu pinepine ana nā te pakaru o te RCD, nā te hapa whakawhitiwhiti kōrero rānei, ka pā ki te ingoa o te kaiwhakahaere, ā, ka arahi pea ki ngā whiu.

21.3. Te Whakapūmau i te Whakamātautau Wera

Kei te whakawhanakehia ngā paerewa hou (hei tauira, mā te IEC me te SAE) hei whakataurite i te huarahi e pānuitia ai te "Tere Utu Nui". I tēnei wā, ka kī pea he 350kW te utu hiko engari ka taea anake te pupuri mō te 5 meneti i mua i te wera nui. Kei te neke te umanga ki te paerewa "Whakatauranga Mana Tonu", e hiahiatia ana kia whai whakamātautau ahotea 2-hāora ngā utu hiko i ngā pāmahana tino pai (tae atu ki te 40°C, 45°C rānei) me te kore e mutu, e whakawhāiti rānei.

22. Papakupu: Ngā Kupu Matua mō te Hanganga EV Manawanui

• Whakatauranga Mana Tonu:Ko te taumata mana ka taea e te rihi hiko te pupuri tonu mō ake tonu atu i te pāmahana taiao kua whakaritea — ko te ine te whakakapi i ngā tau hokohoko "tihi" kua whakanuia.
• Te Whakakore i te Whakakorenga:Ko te whakaiti aunoa i te mana whakaputa hei tiaki i ngā wāhanga mai i te wera nui; kāore te rihi e heke te pāmahana i te 35°C e tuku i tōna mana matua i te raumati.
• Te Whakaiti Wera:Ko te wā e tapahia ai te hiko e te rihi hei tiaki i a ia anō — e kiia ana he "wā whakatā" e NEVI, ā, e piki haere ana te maha e ngā pūrongo e pā ana ki te AFIR.
• RCD (Pūrere Auaha Toenga):He taputapu tiaki e motu ana i te turuturu o te hiko; ko te motuhanga whakararuraru tetahi o ngā tino take o te motuhanga o te hiko i ngā taiao makuku.
• NAP (Pūwāhi Uru ā-Motu):Ko te tūāpapa raraunga o te EU e hiahiatia ana e AFIR kia whakaputahia e ngā rihi te tūnga i te wā tūturu.
• OCPP:Te Kawa Whakatuwheratanga o te Pūwāhi Utu — te paerewa whakawhitiwhiti kōrero i waenga i te rihi me te kapua (1.6J me te 2.0.1).
• ISO 15118:Ko te paerewa whakawhitiwhiti kōrero i waenga i te waka me te utu e āhei ai te manatoko Plug & Charge.
• Mono & Utu:Te manatoko aunoa me te nama e hangai ana ki te ISO 15118 e tango ana i ngā kāri, taupānga, me te RFID mai i te wheako taraiwa.
• SPD (Pūrere Ārai Ngaru):He wāhanga e here ana i ngā whakawhiti ngaohiko mai i te uira me ngā takahanga whakawhiti i mua i te taenga ki ngā hikohiko rihi.
• Wā mahi:Ko te ōrau o te wā e wātea ana te rihi me te tuku i te mana katoa — ka arotakehia inaianei e ngā kaiwhakahaere KPI.

23. Whakamutunga: Te Hangarau mō te Take Kino Rawa

I tīmata tēnei aratohu me tētahi pātai māmā: me pēhea tātou e pupuri ai i te ora o ngā hanganga utu ina mahi tahi te whatunga hiko, te rangi, me ngā taputapu ki te whakahē i tēnei? Ko te whakautu, e ai ki ngā upoko, ko te hangarau matatau i ia paparanga. Ko te whakahaere wera te mea huna e ārahi ana i te tutuki i ngā ture: ko te rihi e kore e taea te whakaheke i te wera e kore e taea te pupuri i tōna mana whakatauranga, ā, ko te rihi e kore e taea te pupuri i tōna mana whakatauranga, e ai ki ngā whakamāramatanga hou i te Wāhanga 21, kua heke iho. Ko te pumau whakawhitiwhiti kōrero te pou tuarua — ehara te ISO 15118 me te OCPP i te mea whai hua engari ko ngā tikanga e whakaatu ana i te wātea ki ngā kaiwhakahaere me ngā taraiwa.

• Tauwhāitihia te mana tonu i ngā pāmahana taiao tūturu, ā, whakakahoretia ngā whakatauranga tino teitei anake.
• Tiakina te wātū, kaua ko ngā taputapu anake— Mā ngā RCD, te tiaki i ngā ngaru nui, me te auau o ngā whakawhitiwhiti kōrero ka rere tonu ngā moni whiwhi.
• Inehia te wā mahi kia rite ki te mahi a ngā kaiwhakahaere, me te wātea o te mana katoa, me te hoahoa i tō hokonga huri noa i taua tau.
• Kōwhiria he hoa mahi hei whakamātautau mō te take kino rawa atu— 40°C ngā rā, te hau takutai makuku, me te haruru o te whatunga whatunga — i mua i tō mahi.

He mārama te aronga ture: kei te neke a NEVI me AFIR mai i te pūrongo wātea ki te pūrongo wātea mana-katoa, ā, ko te mahi wera te taurangi e kore e taea e te nuinga o ngā kaiwhakahaere te rūpahu. Nō reira, ehara i te mea utu nui te haumi ki te whakamatao wai, ki ngā tawhē whakahekenga pono, me te taupūtanga whakawhitiwhiti kōrero - koinei te inihua iti rawa mō te korenga o te tutuki i ngā ture ka taea te utu i te whai wāhi ki te putea, ki te urunga rānei ki te mākete.
