I te rongonuitanga o ngā ariā haereere matomato me te whanaketanga tauwhiro, kua noho ngā kāreti korowha hiko hei wāhi tautoko nui mō ngā papa korowha huri noa i te ao. Hei "ngakau" o te waka katoa, ko te pākahiko te mea tika hei whakatau i te manawanui, te mahi me te haumaru. Mai i te pākahiko waikawa-mata tuatahi ki te pākahiko lithium rino phosphate (LiFePO4) matua o nāianei, kua tino whakapai ake te whanaketanga hangarau i te wheako whakamahi me te whai huatanga o te mahi a te kāreti korowha. Ka arotahi tēnei tuhinga ki ngā painga o LiFePO4 ki te whakataurite ki ngā pākahiko waikawa-mata tuku iho e pā ana ki te haumaru, te roa o te huringa, te mātotoru o te pūngao, te urutau ki te pāmahana me te tere utu.
Ngā herenga o ngā pākahiko waikawa-mata
I mua, i whakamahia whānuitia ngā pākahiko waikawa-mata i roto i ngā kāreti korowha nā te iti o te utu me te hangarau kua pakari. Heoi, he maha ngā āputaputa: he taumaha, he nui te wāhi e nohoia ana, ā, ka heke te wheako whakahaere o te waka katoa; he nui ngā whakaritenga tiaki me te hiahia kia tāpirihia ki te wai whakapūkara i ngā wā katoa, ki te kore ka ngāwari ki te whanariki ka whakapoto i tō rātou ora. Hei tāpiri, ko te huringa ora o ngā pākahiko waikawa-mata he tata ki te 300-500 ngā wā, ā, ko te whakakapinga pinepine ka piki ake te utu whakamahinga mō te wā roa.
Ngā Painga o ngā Pūhiko LiFePO4
Haumaru
He tino teitei te pumau o ngā pākahiko LiFePO4 ki te wera me te matū, kāore e ngāwari ki te rere wera, ki te mura rānei, ā, he pai mō te taiao, kāore hoki e paitini. I raro i ngā āhuatanga rerekē pēnei i te pāmahana teitei, te ara iahiko poto rānei, he nui ake te haumaru o te LiFePO4 i ērā atu pūnaha pākahiko lithium, ā, ka taea te whakarato i ngā taurangi whakamahinga pono ake mō ngā kaata korowha.
Te Ora Huringa
He roa ake te ora huringa o ngā pākahiko LiFePO4 i ērā o ngā pākahiko waikawa-mata. I te nuinga o te wā, neke atu i te 2,000 ngā wā, ā, ko ngā hua kounga teitei ka eke ki te 3,000-5,000 ngā wā, ko te tikanga ka taea te whakamahi tonu mō te 5-10 tau i raro i te tikanga o te tukunga hohonu kotahi i te rā. He rerekē, ka pirau te kaha o ngā pākahiko waikawa-mata ki raro iho i te 80% o te kaha taketake i muri i te 500 ngā huringa, me te hiahia kia maha ake te whakakapinga, ā, ka nui ake te utu tiaki me te ngaronga o te wā whakatā.
Te Kīanga Pūngao
He tohu nui te mātotoru o te pūngao mō te hangarau pākahiko. I te kaha kotahi, ko te taumaha o te pākahiko LiFePO4 he tata ki te 1/3 noa iho o te taumaha o te pākahiko waikawa-mata, ā, ko te rahinga he tata ki te 1/2, ka tino whakaiti i te taumaha o te waka, ka whakapai ake hoki i te whānuitanga taraiwa me te kaha kawenga o te waka. Hei tāpiri, ko te hohonutanga o te tukunga (ka taea e te DoD te eke ki te 80-100%) ka piki ake te tere whakamahinga pūngao whai hua, ko te DoD tino pai o te pākahiko waikawa-mata he tata ki te 50% noa iho, ka moumou nui te mana pea.
Te Āheitanga ki te Whakarerekē i te Pāmahana
I te taiao pāmahana iti, ka tino heke te mahi a te pākahiko waikawa-mata, ā, ka taea e te ngaronga kaha te neke atu i te 50%; i te mea ka taea tonu e te pākahiko LiFePO4 te pupuri i te neke atu i te 80% o te kaha me te putanga ngaohiko i te -10°C, ā, ka taea e te pāmahana whakahaere iti rawa te eke ki te -20°C, he pumau ake i te takurua, i te ata makariri rānei o te papa tākaro.
Te Āheinga Utu Tere
Ka tautokohia e te pākahiko LiFePO4 te tere utu teitei ake (tae atu ki te 0.5C, tae atu ki te 1C), ka whakapotohia te wā tatari utu, ā, ka pai ake te pai o te hurihanga o te waka. He rerekē, ko te tere utu e taunakitia ana mō ngā pākahiko waikawa-mata he 0.1C–0.2C anake, ā, he maha ngā wā ka pau te 6–8 hāora hei utu katoa, he uaua ki te whakatutuki i ngā hiahia o ngā mahi auau teitei.
Te Utu me te Uara Whānui
Ahakoa he 30–50% teitei ake te haumitanga tuatahi o ngā pākahiko LiFePO4 i tērā o ngā pākahiko waikawa-mata, nā te mea he pai te roa o te ora me te iti o ngā āhuatanga tiaki, ka taea te pupuri i te utu kupenga kia rite tonu, kia iti iho rānei i roto i ngā tau e 5. Mō te wā roa, ka whakaitihia e te LiFePO4 te auau o ngā hāora whakakapinga me te tiaki, ā, ko te utu katoa o te mana pupuri (TCO) e hua mai ana he whakataetae ake i tērā o ngā pākahiko waikawa-mata.
Whakamutunga
Mai i te haumaru, te roa o te huringa, te mātotoru o te pūngao, te urutau ki te pāmahana tae atu ki te utu tere, kua whakaatuhia e ngā pākahiko LiFePO4 he painga whānui i roto i ngā tono waka korowha. Mā te arotau tonu o te hangarau me te whakaputanga nui, ka heke tonu te utu o ngā pākahiko LiFePO4. I te heke mai, e whakaarohia ana ka noho hei puna hiko paerewa mō ngā waka korowha hiko, tae atu ki te papa whānui o te waka tere-iti (LSV), ka āwhina i ngā mahi o te papa korowha kia pai ake, kia matomato, kia pumau hoki.
