1. Tirohanga Kaupapa

Kei Ghana, Āwherika tēnei kaupapa, ā, he wāhi whakaaturanga arumoni e whakauru ana i te whakaputa hiko o te rā, te rokiroki hiko pākahiko, me te utu waka hiko. I hangaia mō ngā mahi utu EV, kua noho te teihana hei whakaaturanga ā-rohe mō ngā tono hiko ma.

Ko te kaha o te whakawhiti hiko ā-rohe he 120 kVA anake . Nā te iti o te kaha o te whatunga hiko me te maha o ngā motuhanga hiko, kāore e taea e te whatunga hiko o nāianei te tautoko i ngā teihana utu katoa e mahi ana i te mana katoa, ā, ka tino whakawhāiti i te kaha utu o te teihana me te whai huatanga o te mahi.

Hei whakatika i te korenga o te kaha o te whatunga hiko me te kore pono o te tuku hiko, i whiriwhiria e te kiritaki tā mātou kāpata rokiroki hiko pākahiko 125 kW/261 kWh , me te pana whakawhiti pūmau STS me te pūnaha waka kawe hiko photovoltaic.

I raro i ngā āhuatanga whatunga hiko noa, ka mahi tahi te pūnaha rā, te pūnaha rokiroki pākahiko, me te whatunga hiko ratonga hei tautoko i ngā taputapu utu i te kaha katoa. Mēnā ka motu te whatunga hiko, ka oti i te pūnaha te whakawhiti mai i te hononga whatunga ki te mahi kore-whatunga i roto i te hēkona kotahi. Ka whakawetohia ngā utu tere DC kaha-teitei mō te wā poto, i te mea ka haere tonu te pūnaha ki te tuku hiko ki ngā taputapu utu AC mō te 5–8 hāora pea , kia mau tonu ai ngā ratonga utu nui.

2. Nga Taipitopito Kaupapa

Whakamahinga 2.1

He kaupapa arumoni noa tēnei o tētahi pūnaha utu hiko-pūkoro-rā kua whakauruhia.

E toru ngā wero nui i pā ki te teihana utu hiko i Ghana:

• Te tono utu teitei
• Te iti o te kaha whatunga ā-rohe
• Pūnaha hiko kore pono

Kāore e taea te tautoko i ngā taputapu utu katoa i te wā kotahi mēnā ka whakawhirinaki anake ki te whatunga hiko. Me nui te haumi me te roa o te tukanga hanga me te whakaaetanga mō te whakapai ake i te kaha o te whakawhiti hiko.

Ka whakaputa tika te taunga waka photovoltaic i te hiko ma i te papaanga, ā, ka tāpirihia e te pūnaha rokiroki hiko pākahiko te whatunga hiko i ngā wā e nui ana te tono utu. Ka whakaratohia hoki e te pūnaha he whakawhiti tere ohorere i te wā e motu ana te whatunga hiko.

Ka tautokohia e tēnei otinga ngā mahi utu-katoa i raro i ngā āhuatanga noa, me te pupuri tonu i ngā ratonga utu nui i te wā e motu ana te hiko. Ka whakaitihia te whakawhirinaki ki te hiko o ngā ratonga whakahaere, ka whakaitihia ngā utu whakahaere, ā, he tino pai mō ngā teihana utu EV arumoni i ngā rohe o Āwherika he ngoikore, he koretake rānei ngā whatunga hiko.

3. Ngā Painga Matua o te Kaupapa

3.1 Te wikitoria i ngā herenga o te kaha o te whatunga

Mā te pūnaha rokiroki pūngao 125 kW/261 kWh ka taea te tāpiri atu ki te iti o te pūnaha hiko, ā, ka taea e te teihana utu te mahi pono ahakoa te iti o te kaha o te whakawhiti hiko 120 kVA.

3.2 Te Whakahaere Pūngao Rā, te Rokiroki, me te Whatunga kua Whakaritea

Ka mahi tahi te pūnaha photovoltaic, te pūnaha rokiroki pākahiko, me te whatunga ratonga me te mohio ki te tautoko i te tono utu. Ka whakanui ake tēnei i te whakamahinga o te pūngao rā ma, ā, ka whakaitihia te hiko e hokona ana mai i te whatunga.

3.3 Te Mahi Tonu i te Wā e Motu ana te Hiko

Mā te STS ka taea te whakawhiti tere ki te whatunga hiko me te whakawhiti ki waho o te whatunga hiko. I te wā e motu ana te hiko, ka taea tonu e te pūnaha te tuku i ngā taputapu utu AC mō te 5–8 hāora pea, kia mau tonu ai te mahi a ngā ratonga utu nui.

3.4 Te Whakaiti i ngā Utu Hanganga me ngā Utu Whakahaere

Mā te otinga nei ka karohia te utu nui me te wā roa o te whakatinanatanga e pā ana ki te whakapai ake i te whakawhiti hiko. Mā te whakamahi-ā-ringa o te rā, te tautoko i te kawenga teitei, me te rokiroki pūngao ka āwhina hoki ki te whakaiti i te hiko me ngā whakapaunga whakahaere mō te wā roa o te teihana.
