He pēhea te uaua o te tāuta i tētahi rihi hiko?

I te mea ka tipu haere te whakamahi i ngā waka hiko (EV), he maha ngā kaipupuri hou e pātai ana: "He pēhea te uaua o te tāuta i tētahi rihi EV ki te kāinga?" Ko te whakautu kei runga i tō tautuhinga hiko, te momo rihi, me te mea kei te whakaaro koe ki te mahi-ā-ringa, ki te utu rānei i tētahi tohunga.

I roto i tēnei aratohu whānui, ka hipokina e mātou:
✔ Te uaua o te tāutanga rihi EV
✔ Tāutanga DIY vs. tāutanga ngaio
✔ Ngā whakaritenga hiko me ngā wero noa
✔ Ngā utu me te wā e pau ana
✔ Ngā whakaaetanga, ngā ture, me ngā whakaaro mō te haumaru

1. He pēhea te uaua o te tāuta i tētahi rihi hiko? (Whakautu Tere)

Mō te nuinga o ngā kaipupuri whare, he kaupapa hiko ngāwari ki te matatau te tāuta i tētahi rihi EV.

• Mena kei a koe tētahi ara iahiko 240V (pēnei i te putanga whakamaroke), he tino māmā noa iho.
• Ki te hiahia koe ki tētahi whakahoutanga ara iahiko, ki tētahi panera rānei, ka nui haere te uaua.
• Ka taea te tāuta i a koe anō engari kāore i te tūtohutia mēnā kāore koe i te mōhio ki te hiko.

Ko te nuinga o te iwi ka utu i tētahi kaimahi hiko whai raihana, inā koa mō ngā rihi hiko waea-pūmau.

2. Ngā momo utu hiko me te uauatanga o te tāutanga

A. Taumata 1 Taumata 1 (Pūrua 120V – Ngāwari rawa atu)

• Mono-ā-tākaro (e whakamahi ana i te putanga hiko noa o te whare).
• Kāore e hiahiatia he tāutanga, engari he tino puhoi (3-5 maero te tawhiti i ia hāora).
• Pai rawa atu mō: Ngā taraiwa ohorere, ngā taraiwa iti rānei te maero e haere ana.

B. Taumata 2 o te Rīhi (240V – Tino Noa)

• He waea mārō, he mono rānei (putanga NEMA 14-50 / 6-50).
• Me whai hiko motuhake 240V (30-50 amps).
• Uauatanga tāutanga: Waenga ki te teitei (e taunakihia ana kia whakamahia he tohunga hiko).

C. Utu Tere DC (Mō te Whakamahinga Arumoni Anake)

• 480V+ (kāore e whai hua mō ngā kāinga).
• Me whakapai ake i ngā hiko.

3. Ngā Take Matua e Pā Ana ki te Uauatanga o te Tāutanga

✔ Te kaha o te papa hiko o tō whare

• Me whakahou ake pea ngā panera mō ngā whare tawhito (mēnā kei raro iho i te 100-200A).
• Me tatau te kawenga kia kore ai e taumaha rawa te pūnaha.

✔ Te tawhiti mai i te Paewhiri ki te Rīhi

• He roa ake ngā oma waea = he nui ake ngā utu me te uauatanga.
• Me tutuki ngā paipa wai me ngā waea i ngā ture ā-rohe.

✔ Tāutanga Waea-Matuka vs. Tāutanga Mono-Whakauru

• He waea pūmau (he pumau ake, he tere ake te utu).
• Mono-ā-roto (he māmā ake te whakakapi, te nuku rānei i muri mai).

✔ Ngā Whakaaetanga me ngā Tirotiro ā-Rohe

• He maha ngā rohe e hiahia ana kia whakaaetia ngā tāutanga rihi EV.
• Ka tukuna e ētahi kamupene ratonga he utu whakahoki mō ngā tāutanga ngaio.

4. Hipanga-i-te-Hipanga: He aha ngā mea e hiahiatia ana mō te Tāuta i tētahi Rīhi EV?

Hipanga 1: Kōwhiria te Rīhi Tika

• Ko ngā rihi hiko 7kW ki te 11kW te mea tino noa mō ngā kāinga.
• Mā ngā rihi atamai (hei tauira, JuiceBox, Wallbox, Tesla Wall Connector) ka taea te whakarite me te aroturuki i te hiko.

Hipanga 2: Tirohia tō Paewhiri Hiko

• He wāhi kei roto hei tāuta i tētahi pūwehe hiko 240V hou?
• Kei raro iho i te 80% te kaha o te kawenga katoa? (Whakaritenga NEC).

Hipanga 3: Whakahaerehia te Waea mai i te Paewhiri ki te Tauwāhi Tautuhinga

• Waea parahi 6 AWG, 4 AWG rānei (i runga i te amperage).
• Tērā pea e hiahiatia he parenga paipa ki waho.

Hipanga 4: Tāutahia te Rīhi me te Whakamātautau

• Te whakapiri pakitara (mō ngā waeine waea mārō).
• Te tiakitanga GFCI (e hiahiatia ana e te waehere i roto i ngā wāhanga maha).

Hipanga 5: Whakaaetanga me te Tirotiro (Mēnā e Hiahiatia ana)

• Me tirotirohia te taputapu i mua i te whakamahinga i ētahi tāone.

5. Ka taea e koe te tāuta i tētahi rihi hiko DIY?

✅ Ka taea mēnā:

• He wheako hiko tōu (ehara i te mea ko te whakawhiti rama anake).
• Kua whai ara iahiko 240V tō whare (hei tauira, mō te whakamaroke).
• He pai ki a koe te mahi me ngā waea hiko ngaohiko teitei.

❌ Kāore i te tūtohutia mēnā:

• Me whakahou ake he ara iahiko, he panera rānei.
• Kāore koe i te tino mōhio ki ngā waehere hiko o te rohe.
• Me whai kaimahi hiko whai raihana tō kamupene hiko mō ngā whakahokinga utu.

⚠ Whakatūpato: Mā te tāutanga hē ka pā he ahi, ka pakaru hiko, ka whakakore rānei i tō pūtāhui.
