I roto i te ao o ngā pūnaha hiko o nāianei, ko te rokiroki pūngao he mea nui hei whakarite i te whakaurunga pai o ngā pūtake pūngao hou me te whakapakari i te pumau o te whatunga hiko. Ko ōna tono e kapi ana i te whakaputa hiko, te whakahaere whatunga hiko, me te whakamahinga a te kaiwhakamahi mutunga, ka waiho hei hangarau tino nui. Ko te whāinga o tēnei tuhinga he aromatawai me te tirotiro i te wehewehenga utu, te āhua whanaketanga o nāianei, me ngā tirohanga ā muri ake nei mō ngā pūnaha rokiroki pūngao pākahiko lithium-ion.
Wehenga Utu o ngā Pūnaha Rokiroki Pūngao:
Ko te hanganga utu mō ngā pūnaha rokiroki pūngao e rima ngā wāhanga matua: ngā kōwae pākahiko, ngā Pūnaha Whakahaere Pūhiko (BMS), ngā ipu (tae atu ki ngā Pūnaha Whakawhiti Hiko), ngā whakapaunga hanga me te tāutanga ā-iwi, me ētahi atu whakapaunga hoahoa me te whakatikatika hapa. Mā te tango i tētahi tauira pūnaha rokiroki pūngao 3MW/6.88MWh mai i tētahi wheketere i te Porowini o Zhejiang, ko ngā kōwae pākahiko te 55% o te utu katoa.
Tātaritanga Whakataurite o ngā Hangarau Pūhiko:
Ko te pūnaha rokiroki pūngao lithium-ion e kapi ana i ngā kaiwhakarato taputapu o runga, ngā kaiwhakauru waenga, me ngā kaiwhakamahi mutunga o raro. Kei roto i ngā taputapu ngā pākahiko, ngā Pūnaha Whakahaere Pūngao (EMS), ngā Pūnaha Whakahaere Pūngao (BMS), ki ngā Pūnaha Whakawhiti Mana (PCS). Kei roto i ngā kaiwhakauru ngā kaiwhakauru pūnaha rokiroki pūngao me ngā umanga Hangarau, Hoko, me te Hanga (EPC). Kei roto i ngā kaiwhakamahi mutunga te whakaputa hiko, te whakahaere whatunga, te kai a te kaiwhakamahi mutunga, me ngā pokapū whakawhitiwhiti kōrero/raraunga.
Te Hanganga o ngā Utu mō te Pūhiko Lithium-ion:
Ko ngā pākahiko lithium-ion ngā wāhanga matua o ngā pūnaha rokiroki pūngao hikohiko. I tēnei wā, he maha ngā hangarau pākahiko kei te mākete pērā i te lithium-ion, te waro-mata, ngā pākahiko rere, me ngā pākahiko konutai-ion, he rerekē ngā wā urupare, ngā pai o te tukunga, me ngā painga me ngā ngoikoretanga kua whakaritea.
Ko ngā utu mōkihi pākahiko te wāhanga nui rawa atu o ngā whakapaunga katoa o te pūnaha rokiroki pūngao hikohiko, tae atu ki te 67%. Ko ētahi atu utu ko ngā kaitahuri rokiroki pūngao (10%), ngā pūnaha whakahaere pākahiko (9%), me ngā pūnaha whakahaere pūngao (2%). I roto i te ao o ngā utu pākahiko lithium-ion, ko te rauemi cathode te wāhanga nui rawa atu, tata ki te 40%, ā, i muri mai ko te rauemi anode (19%), te electrolyte (11%), me te wehewehe (8%).
Ngā Auahatanga me ngā Wero o nāianei:
Kua heke te utu o ngā pākahiko rokiroki pūngao nā te hekenga o ngā utu o te lithium carbonate mai i te tau 2023. Nā te whakamahinga o ngā pākahiko lithium rino phosphate i roto i te mākete rokiroki pūngao o te motu i piki ake ai te utu. He maha ngā rauemi pēnei i ngā rauemi cathode me anode, te wehewehe, te electrolyte, te kaikohi au, ngā wāhanga hanganga, me ētahi atu kua kite i ngā whakarerekētanga utu nā ēnei āhuatanga.
Ahakoa rā, kua huri te mākete pākahiko rokiroki pūngao mai i te korenga o te kaha ki te nui rawa o te tuku, e kaha ake ana te whakataetae. Kua uru mai ngā kaitono mai i ngā rāngai kanorau, tae atu ki ngā kaihanga pākahiko hiko, ngā kamupene photovoltaic, ngā kamupene pākahiko rokiroki pūngao hou, me ngā tohunga o te umanga kua roa e tū ana. Ko tēnei urunga mai, me te whakawhānui ake i te kaha o ngā kaitākaro o nāianei, ka tūpono te whakarerekētanga o te mākete.
Whakatau:
Ahakoa ngā wero o te nui rawa o te tuku me te whakataetae nui, kei te tere tonu te tipu o te mākete rokiroki pūngao. I te whakaarohia he rohe tiriona tāra pea, he nui ngā whai wāhitanga tipu, inā koa i waenganui i te whakatairanga tonu i ngā kaupapa here pūngao whakahou me ngā rāngai ahumahi me ngā rāngai arumoni pukumahi o Haina. Heoi, i tēnei wāhanga o te nui rawa o te tuku me te whakataetae kino, ka tono ngā kiritaki o raro i ngā paerewa kounga teitei mō ngā pākahiko rokiroki pūngao. Me whakatū e ngā tāngata hou ngā arai hangarau me te whakawhanake i ngā pūkenga matua kia tupu ai i roto i tēnei whenua hihiri.
Hei whakarāpopototanga, he maha ngā wero me ngā whai wāhitanga kei te mākete Hainamana mō ngā pākahiko lithium-ion me te rokiroki pūngao. He mea nui te mārama ki te wehewehenga o ngā utu, ngā au hangarau, me ngā hihiri o te mākete mō ngā umanga e whai ana ki te whakairo i tētahi aroaro kaha i roto i tēnei ahumahi e tere whanake ana.
