Kua tino heke te maha o ngā pakaru o te pākahiko o ngā waka hiko

Kua tino heke te maha o ngā pakaru o te pākahiko lithium-ion mō ngā waka hiko mono-roto i ngā tau tata nei. Nō nā tata nei i whakanuia e te Tari Hangarau Waka o te Tari Pūngao o Amerika tētahi pūrongo rangahau ko "Rangahau Hou: Kia Pēhea te Roa o te Painga o te Pūhiko Waka Hiko?" I whakaputaina e Recurrent, e whakaatu ana te pūrongo i ngā raraunga e whakaatu ana kua roa te haere o te pono o te pākahiko EV i roto i te tekau tau kua hipa, inā koa i ngā tau tata nei.

I tirohia e te rangahau ngā raraunga pākahiko mai i te 15,000 pea ngā waka ka taea te whakahou i waenga i te tau 2011 me te tau 2023. E whakaatu ana ngā hua he nui ake ngā reiti whakakapinga pākahiko (nā te pakaru, kaua nā te whakahokinga mai) i ngā tau tōmua (2011-2015) i ngā tau tata nei (2016-2023).

I ngā wāhanga tōmua i te wā i iti ai ngā kōwhiringa waka hiko, i kitea ētahi tauira i ngā reiti pakaru pākahiko, ā, i eke ngā tatauranga ki ētahi ōrau. E whakaatu ana ngā tātaritanga ko te tau 2011 te tau tino nui mō ngā pakaru pākahiko, tae atu ki te reiti tae atu ki te 7.5% haunga ngā whakahokinga. I ngā tau i muri mai, i kitea ngā reiti pakaru mai i te 1.6% ki te 4.4%, e tohu ana i ngā wero tonu mō ngā kaiwhakamahi waka hiko i roto i te tūtaki ki ngā raruraru pākahiko.

Heoi, i kite a IT House i tētahi panonitanga nui mai i te tau 2016, i reira ko te reiti whakakapinga rahunga pākahiko (haunga ngā whakahokinga) i whakaatu i tētahi pūwāhi panoni mārama. Ahakoa i noho tonu te reiti rahunga teitei rawa atu i te 0.5%, i te nuinga o ngā tau i kitea ngā reiti i waenga i te 0.1% me te 0.3%, e tohu ana i tētahi whakapainga tekau-whakarea nui.

E ai ki te pūrongo, ko te nuinga o ngā hapa ka whakatauhia i roto i te wā whakamana a te kaihanga. Ko ngā whakapainga o te pono o te pākahiko nā ngā hangarau kua pakeke ake pērā i ngā pūnaha whakamatao pākahiko wai hohe, ngā rautaki whakahaere wera pākahiko hou me ngā matū pākahiko hou ake. Haunga tēnei, he mea nui anō hoki te whakahaere kounga pakari ake.

I te titiro ki ngā tauira motuhake, ko te Tesla Model S me te Nissan Leaf o mua te mea i nui rawa ngā reiti pakaru o te pākahiko. I tino rongonui ēnei waka e rua i te wāhanga mono-mai i taua wā, ā, i piki ake ai te reiti pakaru toharite whānui:

Tauira S Tesla 2013 (8.5%)

Tauira Tesla S 2014 (7.3%)

Tauira S Tesla 2015 (3.5%)

Nissan Leaf 2011 (8.3%)

Nissan Leaf 2012 (3.5%)

I ahu mai ngā raraunga o te rangahau i ngā urupare mai i te 15,000 pea o ngā kaipupuri waka. He mea tika kia kīia ko te take matua mō ngā whakahokinga nui o ngā Chevrolet Bolt EV / Bolt EUV me Hyundai Kona Electric i ngā tau tata nei ko ngā pākahiko LG Energy Solution he hapa (ngā raruraru hanga).
