He wāhanga: He APU (Auxiliary Power Unit) taraka hou kua whakawhanakehia e RoyPow, he mea whakakahangia e ngā pākahiko lithium-ion hei whakaoti rapanga i ngā ngoikoretanga o ngā APU taraka o nāianei kei te mākete.
Kua hurihia te ao e te pūngao hiko. Heoi, kei te piki haere te auau me te kaha o te korenga o te pūngao me ngā āhuatanga taiao. Nā te taenga mai o ngā rauemi pūngao hou, kei te tere piki haere te hiahia mō ngā otinga pūngao whai hua, haumaru ake, me te pumau. Pērā anō hoki te hiahia mō te taraka All-Electric APU (Auxiliary Power Unit).
Mō te tini o ngā taraiwa taraka, ka noho ko ā rātou waka wira-18 hei kāinga mō rātou i tawhiti atu i te kāinga i aua haerenga roa. He aha ngā taraiwa taraka i runga i te rori e kore ai e pai ki te whakamarie o te hauhautanga i te raumati me te wera i te takurua pērā i te kāinga? Hei painga mō tēnei painga, me noho puku te taraka mēnā he otinga tuku iho. Ahakoa ka taea e ngā taraka te whakamahi i te 0.85 ki te 1 karani wahie mō ia hāora o te noho puku. I roto i te tau, ka taea e te taraka haere roa te noho puku mō te 1800 hāora, me te whakamahi tata ki te 1500 karani o te tīhiera, arā, tata ki te 8700USD te para wahie. Ehara i te mea ka moumou wahie me te utu moni anake te noho puku, engari he kino hoki ngā pānga ki te taiao. He nui te hauhā waro e tukuna ana ki te āhuarangi ka tāpirihia i roto i te wā, ā, ka whai wāhi nui ki te huringa āhuarangi me ngā take parahanga hau huri noa i te ao.
Koinei te take me whakatinana e te American Transportation Research Institute ngā ture me ngā ture ārai-noho, me te wāhi e whai hua ai ngā waeine hiko āwhina tīhi (APU). Mā te tāpiri i tētahi mīhini tīhi ki te taraka, ka whakaratohia he pūngao mō te whakamahana me te hauhautanga, whakawetohia te mīhini taraka, ā, ka noho hei mea tūturu te noho pai o te kāpata taraka. Mā te APU taraka tīhi, ka taea te whakaiti i te 80 ōrau o te whakapaunga pūngao, ka tino whakaitihia te parahanga hau i te wā kotahi. Engari he nui rawa ngā mahi tiaki mō te APU tahunga, me te hiahia kia whakawhiti hinu auau, kia tātari wahie, kia tiakina whānuitia (ngā ngongo, ngā here, me ngā takirere). Ā, kāore e taea e te taraiwa taraka te moe nā te mea he nui ake tōna haruru i te taraka tuturu.
I te pikinga ake o te hiahia mō te hauhautanga mō te pō e ngā kaikawe ā-rohe me ngā āhuatanga iti o te tiaki, ka puta mai ngā APU taraka hiko ki te mākete. Ka whakakahangia ēnei e ngā pākahiko tāpiri kua tāutahia ki roto i te taraka, ā, ka utaina e te alternator i te wā e huri ana te taraka. I te tīmatanga, ko ngā pākahiko waikawa-mata, hei tauira, ko ngā pākahiko AGM i tīpakohia hei whakakaha i te pūnaha. Ka whakakahangia e te pākahikotaraka APUka nui ake te whakamarie o te taraiwa, ka nui ake te penapena wahie, ka pai ake te kimi/pupuri taraiwa, ka iti ake te noho, ka iti ake ngā utu tiaki. Ahakoa te mahi a te taraka APU, ko ngā āheinga whakamatao te mea nui. E tata ana ki te 30% te kaha whakamatao o te APU tīhiera i te pūnaha APU pākahiko AGM. Heoi anō, ko te wā whakahaere te pātai nui a ngā taraiwa me ngā kahui waka mō ngā APU hiko. I te toharite, ko te wā whakahaere o te APU hiko katoa he 6 ki te 8 hāora. Arā, me tīmata pea te tarakihana mō ētahi hāora hei whakahou i ngā pākahiko.
Nō nā tata nei i whakarewahia e RoyPow te pākahiko lithium-ion kotahi-mutu All-Electric APU (Auxiliary Power Unit). Ki te whakatauritea ki ngā pākahiko waikawa-mata tuku iho, he pai ake te whakataetae o ēnei pākahiko LiFePO4 i runga i te utu, te roa o te mahi, te whai hua o te pūngao, te tiaki me te tiaki taiao. Ko te hangarau hou o te taraka pākahiko lithium All-Electric APU (Auxiliary Power Unit) kua whakatakotoria hei whakatika i ngā ngoikoretanga o ngā otinga APU taraka tīhi me te hiko o nāianei. Kei roto i tēnei pūnaha he alternator 48V DC atamai, ina oma te taraka i runga i te rori, ka whakawhiti te alternator i te pūngao miihini o te miihini taraka ki te hiko ka rongoa ki roto i te pākahiko lithium. Ā, ka taea te utu tere i te pākahiko lithium i roto i te kotahi ki te rua hāora, ā, ka whakarato hiko ki te HVAC e oma tonu ana tae atu ki te 12 hāora hei whakatutuki i te hiahia mō te taraka roa. Mā tēnei pūnaha, ka taea te whakaiti i te 90 ōrau o te utu pūngao i te noho puku, ā, i whakamahia he pūngao matomato me te ma anake hei utu mō te tīhi. Ko te tikanga, kāore he tukunga ki te hau me te kore he parahanga haruru. Ko ngā pākahiko lithium he mea e kitea ana i te kaha o te whakamahi i te pūngao, he roa te ora o te mahi, ā, kāore he mahi tiaki, ā, ka āwhina i ngā taraiwa taraka kia kaua e manukanuka ki te korenga o te pūngao me ngā raruraru tiaki. Heoi anō, ko te kaha whakamatao o te hauhautanga 48V DC o te taraka All-Electric APU (Auxiliary Power Unit) he 12000BTU/h, he tata ki ngā APU tīhiera.
Ko te taraka pākahiko lithium hou, he APU Hiko Katoa (Auxiliary Power Unit) te ia o ngā momo rerekē ki te APU tīhiera, nā te iti o te utu hiko, te roa o te wā e whakamahia ana, ā, kāore he tukunga.
Hei hua "whakaweto i te miihini me te ārai i te noho puku", he pai te pūnaha lithium hiko katoa a RoyPow ki te taiao, ā, he pumau hoki mā te whakakore i ngā tukunga, me te whai i ngā ture ārai-noho puku me te ārai-tukunga puta noa i te motu, tae atu ki ngā whakaritenga a te Poari Rauemi Hau o California (CARB), i hangaia hei tiaki i te hauora o te tangata me te aro atu ki te parahanga hau i te kawanatanga. Hei tāpiri, ko ngā whanaketanga o te hangarau pākahiko kei te whakaroa i te wā whakahaere o te pūnaha āhuarangi, e āwhina ana ki te whakaiti i ngā āwangawanga a ngā kaihoko mō te manukanuka hiko. Ko te mea whakamutunga engari ehara i te mea iti rawa, he nui te uara hei whakapai ake i te kounga moe a ngā kaitaraiwa taraka hei whakaiti i te ngenge o te taraiwa i roto i te umanga taraka.
