I roto i te ao waka hiko (EV), he mea nui te pupuri i ngā pākahiko i te pāmahana tika kia pai ai te mahi. I te mea ka piki haere te rongonui o ngā waka hiko, kei te mahi tonu ngā kamupene ki ngā huarahi auaha hei whakarite kia pai te mahi a ā rātou waka i ngā āhuatanga huarere katoa. Ko tētahi o aua whanaketanga ko ngā whakamahana whakamatao pākahiko, me te hangarau PTC (Positive Temperature Coefficient) kei mua i tēnei whanaketanga.
Whakamahana whakamatao PTCs, e mōhiotia ana kowhakamahana whakamatao pākahikoHe wāhanga matua ngā s i roto i te maha o ngā waka hiko hou. Ko tana mahi matua he whakahaere i te pāmahana o te pākahiko o tō waka, kia pai ai te mahi me te roa o te wā. He mea nui rawa tēnei i ngā āhuarangi makariri, nā te mea ka pā kino te pāmahana iti ki te pai o te pākahiko me tōna kaha ki te utu.
Ka whakamahia he huānga PTC mō ngā whakamahana whakamatao PTC, he ātete e piki ake ana tōna ātete i te pāmahana. Nā tēnei āhuatanga whakahaere-ake, he mea whai hua, he mea pono hoki mō ngā tono whakamahana pākahiko. Ina heke te pāmahana o te pākahiko ki raro i te taumata e hiahiatia ana, ka whakahohe aunoa te whakamahana whakamatao PTC ki te whakaputa wera me te whakamahana i te whakamatao huri noa i te pākahiko. Kia tae ki te pāmahana tino pai, ka whakaitihia e te whakamahana te whakapaunga hiko, ka pai ake te whakamahinga pūngao.
Ko tētahi o ngā painga o te whakamahana whakamatao PTC ko tōna kaha ki te whakamahana i te pākahiko me te pupuri i te pāmahana e hiahiatia ana ahakoa kāore te waka e whakamahia ana. He tino painga tēnei mō ngā kaipupuri EV e noho ana i ngā āhuarangi makariri, nā te mea ka whakarite kia noho pai tonu te pākahiko, ahakoa te pāmahana o waho.
Hei tāpiritanga, nā te hoahoa me te hangarau o ngā whakamahana whakamatao PTC he mea haumaru, he mea pono hoki mō ngā kaihanga waka hiko. Ko tōna āhuatanga whakahaere-ake ka ārai i te wera nui, ka waiho hei otinga iti te tiaki me te roa mō ngā hiahia whakamahana pākahiko. He mea nui tēnei hei whakaaroaro mā ngā kaihanga waka hiko e hiahia ana ki te whakarato waka roa, pono hoki ki ngā kiritaki.
I te mea kei te piki haere tonu te hiahia mō ngā waka hiko, ka nui haere te hiranga o te hiahia mō ngā otinga whakamahana pākahiko whai hua. Ka pā nui te makariri ki te whānuitanga me te mahi a ngā waka hiko, nō reira he mea nui kia haumi ngā kaihanga ki ngā pūnaha whakamahana pono, whai hua hoki.He whakamahana EV PTCKa whakaratohia e ngā waka hiko tētahi otinga whai hua, auaha hoki mō tēnei raruraru, e āhei ai te whakahaere i ngā waka hiko i tōna taumata pai ahakoa te āhua o te rangi.
Hei whakamutunga, ko te whanaketanga o ngā whakamahana whakamatao pākahiko, inā koa ko ērā e whakamahi ana i te hangarau PTC, he whanaketanga nui i roto i te ao o ngā waka hiko. He mea nui te mahi a ēnei whakamahana ki te whakarite kia mahi ngā pākahiko waka hiko i ngā pāmahana tino pai, kia roa ai te mahi me te roa o te ora. I te haere tonu o te whānui o te mākete waka hiko, ka piki ake te hiahia mō ngā otinga whakamahana whai hua, ka waiho ngā whakamahana whakamatao PTC hei taonga nui ki ngā kaihanga me ngā rangatira waka hiko.
