He iti noa ranei he mate noa i te ao. Kia whakamahia e ratou i te nuinga o nga mea e whakamahi ana koe i runga i to raatau wa, mai i nga mea kua kitea he wanaunga ki nga pūtonga reo me o raatau whakamahi hei kōrero i runga i o koutou whānau me o koutou hoa. I tenei pukapuka, ka kōrero tātou mō ngā taipu matua e rua o ngā paerahi, Ni-MH me Li-ion. Ka tae atu nei ki te whakaatu i aheahea me ngā pai me ngā hapa o enei taipu e rua o ngā paerahi, me te itinga rawa o tētahi hei whakamahi mo o raatau rīpoata.
Ngā Rerekētanga Kiwa Ni-MH me Paerahi Li-ion
Tōnā i mua, ngā pū kawe Ni-MH. Ka taea e ēnei pū te whakahoki i te tuatahi, nā tēnā kaore koe i te wā kia hokona i ngā pū hou atu. He mea iti rawa anō rātou i runga i ngā pū Li-ion, ā, ka noho he wā nui hei whakamahia. Tētahi momo whakatūpato i a Ni-MH heoi, kaore rātou i te mīhini nui i te wā moenga i runga i ngā pū Li-ion. Nā te iti o te mana moenga, ka whakaheke kē tēnei i te wā e hanga ai ngā tūruki kia whai mana i te wā ki te whakahokia anō. E tere ana hoki ngā pū Ni-MH ki te whakahokia, ko tēnā he mea kore whiwhi i mua i te mea koe e hiahia ana ki te whakamahi i tō hohipera tūroko. Nā runga anō hoki i ngā pū Li-ion, he nui rawa atu rātou, he nui rawa atu, me te iti noa iho.
I tēnei wā, whakarerea kia whakaaro ki ngā pūtahi Li-ion. Nō te mea he iti noa iho te moni o ngā pūtahi Lipo i runga i ngā pūtahi Ni-MH, engari he nui ngā paunga. He nui hoki te tirotiro ēneji i roto i ngā pūtahi Li-ion, e hīnā ana i tērā ka taea e rātau te whakahaere i ōu ipurangi mō te wā e roa ake. He aha anō hoki te wā e tae ana ki te whakapai i a rātau i runga i ngā pūtahi Ni-MH, he paihikara tuatahi kei te waenganui i ngā wā e iti ana. Mēnā ka whakatūhia i te iti me te manahe, ka noho haumaru ake i te whakamīharo. Ahakoa tēnei, kaore i te tino pūmau i runga i te wā e roa nei i raro i ngā pūtahi Ni-MH, nō te mea kaore i te taea te whakahoki i a rātau i te wā e maha ana. Ko tēnei e mahi nei hei whakaae ki te whakamahi i a rātau mō te wā e roa, engari me whakatakoto i nā rātau i mua i ngā pūtahi Ni-MH.
Tono Whakahaere Pūtahi
Ki te mohio koe i te whakahaere pai ake o nga pūtahi, me ako koe mo te mea e tuhia nei hei 'momo urunga take'. Ko te momo urunga take he itiiti tonu te roanga take kei roto i tetahi pūtahi ki te roanga whenua. Hei tauira: Nui ake te urunga take o nga pūtake Li-ion i runga i o rātau hoa Ni-MH. E hīnau ana tēnei i te wā e taea ai e rātau te whakawātea i te take mō te wā e hirango ana. Waihoki, ka whakakī ai rātau i te wā e tae atu ana i te pūtake Ni-MH. Āe, ahakoa nui ake te mana o nga pūtake Li-ion, he iti noa rā te wā e taea ai e rātau. Ko te take ko te mea ka heke iho etahi wāwāhi o rātau take i te wā e whai ake ana, ā, ahakoa kaore i whakamahia ake.
Te Kite i te Pūtahi Tika
Pātengi Tīmatanga Mō te Whiriwhironga i te Pūkaha Tika mō Tō Waho Hiahiatia Ki te mea koe e kiteke atu noa ana he aha te pūkaha hei whiriwhiri, ko ngā ture iti nei hei whakamahi. Whakaaro i te wā o tō whakamahi i te tūtohi i te tuatahi. Nā reira, hei tauira, ki te whai wā rawa koe i te tūtohi, ka tēnā koe te pūkaha Li-ion, nā tērā e āhei ana ki te whakapakari haere me te whakawhiti kaha. Ki te kawe mai iho koe i tō waho hiahiatia, nā reira ka taea e koe hoki te whiriwhiri i te pūkaha Ni-MH, nā tērā e pai rawa ana me te tae roa atu. I muri iho, whakaaro i te aha koe e hiahia ana ki te pūkaha iti me te iti. Ki te hiahia koe ki te kaweake, ka haere koe mo te pūkaha Li-ion nā tērā e ea mea ana ki te kawe. Heoi pea, ki te kore koe i te hiahia ki te pūkaha nui me te nui, ka pai hoki te pūkaha Ni-MH.
Nga Ngaehu o ngā Pūkaha Li-ion
He nui ngā paanga o ngā pūtahi Li-ion i runga i te maha o ngā tūtohi, ā, e whakamahia ana i waenga o ngā wā. Nō te mea e haumaru ana ēnei pūtahi i te taumata mana, e tino tae noa ana hoki ki te kawe i waenga i ngā tūtohi pērā i ngā papa me ngā rorohiko. Kāore hoki rātou i te nui, kātahi ka taea te whakauru ki runga i ngā wāhanga iti. He pai rātou mo ngā tono e hiahia ana ki te whakamahi o ngā momo kaha nui, pērā i ngā kāmira e tino āhua ai i ngā whakaahua pai, nō reira ka taea te whakauru i te maha o te kaha. Nei pea, e tautoko ana ngā pūtahi Li-ion i te whakapai motuhake me te whakarite i te kawe i te kaha i te maha o ngā wā. Pūngao Ni-MH , kāore hoki koe e hiahia ana ki ngā pūtahi koe e mate ana i waenganui i tō wā kēmu ranei, ko tō wā whakarongo ranei.
Ngā Paanga Taiao o ngā Pūtahi
He aha tērā kia whakaaro ki ngā whakamahi moana o ngā paunu katoa i te wā e whakatau ana. Ko te niho, he tūtohu nui i whakamahia hei whakatō i ngā paunu Ni-MH, ko te mea nui kei te papa whenua. He cadmium hoki rātou, he āhua kino e whai ake nei i ngā take mōhiohio mā te kore rawa atu i te whakaputu mai i te tika. Ngā paunu Li-ion, nā te mea ka whakatōia ki te raupapa, he mete ingoa iti kē, ka whai ake nei i te hanga i te papa whenua. Ka kitea te whakamamae i te taiao mā te haere ki te whakamahitanga i te raupapa, ka noho pai tonu i te taiao. He mea nui kei runga i ngā paunu Li-ion, he wā e tino wātea ana i te whakawhitinga i runga i ngā paunu Ni-MH, kāore i te maha ngā waiporoporo e puta nei, me te itinga o te whakamahi moana.
