I roto i ngā otinga hiko hou, kei te piki haere te rongonui o ngā pūnaha hiko pūngao rā mō ngā whare me ngā pakihi, e tuku ana i te mana motuhake ki ngā kaiwhakamahi, e whakawātea ana hoki i a rātou mai i ngā herenga me ngā rerekētanga o te whatunga tūmatanui. Ko te pākahiko te pūtake matua e pupuri ana i te mahi pumau me te whakarato i te pūngao kore e mutu.
Kakōrerongā tawhā hangarau matua ongā pākahiko kore-whatungame te whakamārama he aha ngā waeine LiFePO4 te pākahiko pai rawa atu mō ngā pūnaha rā waho-whatunga.
Ngā Tohu Mahi Matua o ngā Pūhiko Hiko Rā i waho o te Whatunga
I te wā e whiriwhiri ana i tētahi pākahiko kore-whatunga, kāore e ranea te titiro noa ki tētahi tawhā kotahi. Me whakahaere he aromatawai katoa o ēnei inenga matua.
1.Haumaru
Ko te haumaru te mea matua hei whakaaroaro. E mōhiotia ana ngā pākahiko pūngao rā LiFePO4 mō tō rātou pumau wera me te matū, ā, he pai ake te pana atu i te rerenga wera i te nuinga.lithium-ionngā tauira.
Me te pāmahana tīmatanga rere wera nui rawa atu—i te nuinga o te wā tata ki te 250°C ki te whakataurite ki te tata ki150–200°C mōNCM me te NCApākahiko—he nui ake te ātete ki te wera nui me te mura. He pumau ā rātouhinu oriwaka ārai te hanganga i te tukunga hāora ahakoa i raro i ngā pāmahana teitei, ka whakaiti ake i te mōrearea o te ahi, o te pahūtanga rānei. Hei tāpiri, ka mau tonu te pumau o te hanganga o ngā pākahiko LiFePO₄ i ngā huringa utu me te tukunga—kāore he huringa hanganga i raro i te 400℃—te whakarite i te pono mō te wā roa me te rangimarie o te hinengaro i roto i ngā taiao uaua. Hei tāpiri, ka taea e ngā kaihanga kete te whakamana me te IEC 62619 me te UL 9540A ki te aukati i te horapa.
2.Te Kaha Tukunga Hōhonu（Te Tari Whakahaere）
Mō te DoD, he painga nui ngā pākahiko pūngao LiFePO4, ka taea te whakatutuki i te DoD pumau o te 80%-95% me te kore he kino. Ko te DoD o ngā pākahiko waikawa-mata ka herea ki te 50% hei ārai i te hekenga pumau o te kaha nā te sulfation pereti.
Nō reira, a10kWhpūnaha rokiroki pūngaoMā te whakamahi i te hangarau LiFePO4 ka taea te whakarato i te 8-9.5kWh o te pūngao ka taea te whakamahi, ko te pūnaha waikawa-mata ia ka taea anake te whakarato i te 5kWh.
3.Te Roanga Ora me te Āheinga Huringa
Ka puta he hua mai i te utu o te haumitanga ki te hangarau LiFePO4 mā te roa o te ora o te hua. Ko ngā mea waikawa-mata ka tere te heke o te mahi i muri i te 300-500 huringa noa iho o te whakamahinga nui.
Engari he roa te roa o te huringa o ngā pākahiko LiFePO4, neke atu i te 6,000 huringa (neke atu i te 80% DoD). Ahakoa kotahi te huringa utu-tukunga ia rā, ka taea tonu te mahi mō te wā roa.tae atu ki15 tau.
4.Te Kīanga Pūngao
Te mātotoru o te pūngao definete nui o te pūngao ka taea e te pākahiko te penapena mō tētahi rahinga, taumaha rānei. He nui ake te mātotoru o te pūngao o ngā pākahiko pūngao rā LiFePO4. Mō te kaha ōrite, he iti ake te rahi me te mama ake te taumaha, e tino penapena ana i te wāhi tāutanga me te whakangawari i te kawe.
5.Te Whai Hua o te Utu
Ko te whai huatanga o te pākahiko LiFePO4 mō te haere-hoki he 92-97%. He iti ake te whai huatanga o ngā pākahiko waikawa-mata, ā, ko te whai huatanga o te haere-hoki he 70-85%. Mō ia 10 kWh o te pūngao rā e hopukina ana, ka hurihia e ngā pūnaha waikawa-mata te 15-25% o te pūngao rā hei para wera. Ā, ko te ngaronga o te pākahiko LFP he 0.3-0.8 kWh noa iho.
6.Ngā Whakaritenga Tiaki
Fngā pākahiko waikawa-mata waipuke rānei, tiaki e kapi ana i tengā tirotiro ā-wā o ngā taumata irahiko me te aukati i te waikura mutunga.
Kāore he tiaki e hiahiatia ana mō ngā pākahiko pūngao rā LiFePO4, ā, kāore e hiahiatia he tiaki.ate whakaritenga o te horoinga wai, te horoinga teihana rānei, te tiaki utu taurite rānei.
7.Te Utu Tīmatanga me te Utu Huringa Ora
He nui ake te utu tīmatanga mō ngā pākahiko LiFePO4.FePO4E whakaatu ana te pūnaha PV 4 i waho o te whatunga i te utu katoa o te mana whakahaere pai ake. Ka taea e rātoukia roa ake te ora o te mahi, ā, kia iti noa te tiaki e hiahiatia ana, me te whakatutuki i te whai huatanga o te pūngao. Ko ngā hua roa o ēnei haumitanga ka hua ake he nui ake te uara katoa.
8.Awhe Pāmahana Whānui
Ka heke te mahi a ngā pākahiko waikawa-mata ina whakamahia i roto i ngā taiao makariri. He whānui ake te awhe pāmahana whakahaere o ngā pākahiko pūngao rā LiFePO4.mai i-20°C ki te 60°C.
9.Te Aroha ki te Taiao me te Oranga Tonu
Kāore he konganuku taumaha i roto i ngā pākahiko pūngao rā LiFePO4 pērā i te mata, e whakamahia ana mōhe kino ki ngātaiao, ā, me whai tikanga hangarua motuhake, uaua hoki. Ko te waikawa whanariki te mea e whakamahia ana i roto i ngā pākahiko waikawa-mata, he waikura, ā, ka taea te wera nui. Ka taea e ngā maringi, ngā turuturu rānei te whakakawa i te oneone me te wai, ka kino ki ngā tipu me ngā mea ora i roto i te wai.
E hia ngā pākahiko pūngao LiFePO4 e hiahiatia ana e koe?
He taahiraa nui te whakatau i te kaha o te pākahiko i roto i te hoahoa pūnaha hiko o waho o te whatunga hiko. Me titiro tātou ki tētahi tauira hei kite i te mahi:
(1) Ngā Whakaaro:
Te Whakamahinga Pūngao o ia Rā: 5 kWh
Ngā Rā o te Mana Motuhake: 2 ngā rā
Pūhiko e taea te whakamahi DoD: 90% (0.9)
Te Whai Hua o te Pūnaha: 95% (0.95)
Ngaohiko Pūnaha: 48V
Pūhiko Kotahi i Kōwhiria: Pūhiko Rā ROYPOW LiFePO4 5.12 kWh
(2) Tukanga Tātai:
Te Hiahiatanga Rokiroki Katoa = 5 kWh/rā × 2 rā = 10 kWh
Te Pūmanawa Pūhiko Katoa = 10 kWh ÷ 0.9 ÷ 0.95 ≈ 11.7 kWh
Tau o ngā Pūhiko = 11.7 kWh÷ 5.12 kWh = 2.28 pākahiko
Whakamutunga: Nā te mea kāore e taea te hoko takitahi i ngā pākahiko, e toru ngā pākahiko e hiahiatia ana e koe, ā, he nui hoki te āputa haumaru e tukuna ana e ēnei pākahiko ki tua atu i tō 10 kWh e hiahiatia ana i te tīmatanga.
Ētahi atu Whakaaroaro i te Wā e Kōwhiri ana i te Pūhiko Rā LiFeO4
üHototahitanga Pūnaha:Tātaitia te ngaohiko pākahiko waho-whatunga ki tō inverter/rīhi, ā, whakamahia he pūmana me te kōtaha utu LFP. Kaua e utu i raro i te 0 °C, tirohia hoki te utunga mōrahi me te iahiko tukunga o te pākahiko ki te rahi o tō inverter.
üTe Tauine me te Hoahoa Modular ā-Mārama:Whakamaherehia te tāpiri i te kaha me ngā kōwae ōrite. Honoa mā roto i ngā pae pahi kia kitea ai e ia aho te roa o te ara ōrite, ā, kia ōrite te ngaohiko i mua i te whakarara kia kore ai e taurite. Whaia ngā rohe raupapa me te whakarara a te kaihanga.
üWaitohu me te Pūtāhui:Me rapu koe i ngā kupu māmā, pērā i ngā tau e hipokina ana, ngā rohe huringa/pūngao, me te kaha mutunga o te pūtāhui. Haunga tēnā, ko ngā waitohu he tiwhikete haumaru (IEC 62619 me UL 1973) me te tautoko ratonga ā-rohe te mea e tika ana kia whiriwhiria.
Pūhiko Rā Rino-Lithium ROYPOW
Ka roa ake te ora o ā mātou pākahiko pūngao rā ROYPOW lithium-rino, ka taea hoki te whakamahi hei whiriwhiri i ngā hoahoa ngāwari, ā, ka whakaitihia hoki ngā whakapaunga whakahaere., ko ēhea ngā otinga tino pai mō rngā kāpata whakamīharotongā pūnaha pūngao rā waho-whatunga mō ngā whare.
