I ngā tau tata nei, kei te puta tonu mai ngā ahi o ngā waka hiko wira-rua, inā koa i te raumati, he ngawari te mura ohorere o te ahi hiko!
E ai ki te rōpū whakaora ahi ā-motu o te tau 2021 i whiwhi i ngā raraunga pirihimana me te ahi i tukuna e te Tari Whakaora Ahi o te Manatū Whakahaere Āwhati, tata ki te 18,000 ngā ahi i puta mai i ngā waka hiko wira-rua me te pakaru o ā rātou pākahiko i pūrongohia puta noa i te motu, i mate ai te 57 tāngata. E ai ki ngā pūrongo, i roto noa i te haurua o te tau 2022 i tēnei tau, e 26 ngā ahi waka hiko wira-rua i Yantai.
He aha te take e maha ai ngā mura o ngā waka hiko wira-rua?
Ko te take matua o te mura ohorere o ngā waka hiko wira-rua ko te rere wera o ngā pākahiko lithium, ko te mea e kiia nei ko te rere wera he tauhohenga mekameka i whakaohohia e ngā momo whakaohooho, ā, ka taea e te wera te whakanui ake i te pāmahana o te pākahiko ki ngā mano nekehanga, ka hua ake he mura ohorere. Ka tere te mura o ngā pākahiko waka hiko wira-rua mēnā ka nui rawa te utu, ka poka, ka wera nui, ka poto te ara iahiko, ka pakaru mai i waho me ētahi atu take.
Me pēhea te ārai i te rerenga wera me te whai hua
He maha ngā take e puta ai te rerenga wera, nō reira me mahi ngā mahi ārai maha hei ārai i te putanga mai o te rerenga wera.
Ko te tino take o te rerenga wera ko te "wera", kia tika ai te pāmahana o te pākahiko, kia pai ai te ārai i te putanga mai o te rerenga wera. Heoi, i te pāmahana teitei o te raumati, kāore e taea te karo i te "wera", me tīmata mai i te pākahiko, kia pai ake ai te ātete ki te wera me te mahi marara wera o ngā pākahiko lithium-ion.
Tuatahi, me aro nui ngā kaihoko ki ngā āhuatanga e pā ana ki ngā pākahiko lithium i te wā e hoko ana i ngā waka hiko wira-rua, me te mea he pai te ātete pāmahana me te mahi whakamarara wera o te rauemi o roto o te pūtau pākahiko. Tuarua, mehemea he teitei te ātete pāmahana o te hononga e hono ana ki te pākahiko i roto i te waka hiko, kia kore ai te hononga e ngohengohe, e pakaru rānei nā te pāmahana teitei, kia maeneene ai te ara iahiko, kia kore ai hoki e puta he ara iahiko poto.
Hei tohunga hononga waka hiko ngaio, e 20 tau te wheako o AmasS ki te rangahau me te whakawhanake i ngā hononga waka hiko lithium, ā, e whakarato ana i ngā otinga hononga kawe-auau mō ngā kamupene waka hiko wira-rua pērā i a SUNRA, AIMA, YADEA. Ko te hononga waka hiko wira-rua pāmahana teitei a AmasS e whakamahi ana i te PBT me te ātete wera, te ātete huarere me ngā āhuatanga hiko pai, ā, ko te pae rewa o te anga kirihou PBT he 225-235℃.
Ko te kaha o te whakahaere paerewa whakamātautau me ngā paerewa whakamātautau tino pai te pūtake mō te whakarite i te kounga o te hononga waka hiko wira e rua.
Taiwhanga Whakaemi
Kua paahitia e ngā hononga waka hiko wira-rua pāmahana teitei te whakamātautau ātete mura, ā, he ātete mura te mahi tae atu ki te ātete mura V0, ka taea hoki te tutuki i te pāmahana taiao o -20 °C ~120 °C. Mō te whakamahinga i te awhe pāmahana taiao i runga ake nei, kāore te anga matua o te hononga waka hiko wira-rua e ngohengohe nā te pāmahana teitei, ka hua ake he ara iahiko poto.
Haunga te kōwhiringa o te pākahiko me ōna wāhanga, te kounga o te rihi waka hiko, he roa rawa te wā utu, ā, ko te whakarerekētanga turekore o te waka hiko wira e rua te mea nui ki te whakapai ake i te mahi haumaru o te pākahiko lithium waka hiko.
