I te taha o te whakawhiti pūngao o te ao me te pikinga ake o te hiahia hiko, kua nekehia ngā pākahiko rokiroki pūngao mai i ngā "taputapu āwhina" ki te "kaikawe matua" o ngā pūnaha pūngao, e uru atu ana ki ngā āhuatanga whakamahinga pūngao rerekē me ngā kaha ahurei. Kei raro nei he whakamārama poto o ō rātou uara matua.
I. 5 Ngā Painga Matua (Kei roto ngā Raraunga Matua)
1. Teitei o te Pūngao me te Roa o te Ora Huringa
- Kiato: Ngā pākahiko lithium rino phosphate (LFP) matua: 150-200Wh/kg; ngā pākahiko lithium tuatoru: neke atu i te 250Wh/kg (he rite te pākahiko whare 10kWh ki tētahi kāpata iti).
- Roanga Ora: E 5,000+ ngā huringa ka tukuna e ngā pākahiko LFP (≥80% te pupuri i te kaha, ka taea te whakamahi mō ngā tau 13+ i te 1 huringa/rā); ka taea e ngā pākahiko ahumahi te neke atu i te 10,000 huringa (hei tauira, e 8 tau te whakahaere o te pūnaha wheketere 2MWh, 2,900+ huringa, kei te 85% tonu te kaha).
2. Whānui te Urutau ki te Pāmahana
- Awhe mahi: -30℃ ki te 60℃.
- Ko ngā putanga pāmahana iti e pupuri ana i te kaha ≥80% i te -20℃ (e whakamahia ana i Siberia mō te hiko kāinga -35℃); ka mahi pūmau ngā tauira pāmahana teitei i te 60℃ (e whakamahia ana i ngā koraha o te Waenganui Rawhiti mō te 55℃ whakatau tata i te tihi-awaawa).
3. Haumarutanga Teitei
- Parenga toru: Rauemi (Te pāmahana pirau wera o te LFP: 800℃ vs. 200℃ mō te lithium toru) → Hanganga (ngā pūtau honikoma + ngā ārai ahi) → Pūnaha (Ka whakaoho te BMS i te whakaweto hiko i roto i te 0.1 hēkona mō ngā āhuatanga rerekē).
- Raraunga o te tau 2024: Te auau aituā ahi ā-whare = 0.003% (he iti iho i te toharite o te ao).
4. Te Whai Huatanga o te Utu Ōhanga
- Te hekenga utu: Neke atu i te 60% i roto i ngā tau 5; Te utu mō ia wae LFP 2024: < RMB 0.6/Wh (pūnaha whare 10kWh: ≤ RMB 15,000).
- Utu Whakahoki: Ngā whare Tiamana (me te hiko pūngao rā): 5-7 tau (€800-1,200/tau te penapena); ngā kaiwhakamahi ahumahi (pūnaha 1MWh): ~4 tau (RMB 150,000-200,000/tau te hua mā te whakatau tata ki te awaawa).
5. Kakariki & Ka taea te hangarua
- Ka huri i te pūngao o te rā/hau ki te hiko pumau; Te tere whakaora rauemi pākahiko LFP: >95%, te lithium tuatoru: >90%.
- Te rahinga hangarua o te ao mō te tau 2024: 12GWh (he rite ki te 150,000 tāne o te whakaiti waro), e tutuki ana i te Ture Pūhiko Hou a te EU me ngā whāinga "Waro Rua" a Haina.
II. Ngā Horopaki Taupānga Matua e 4
1. Whare: Kai-ā-koe + Āhuatanga ohorere
- Whakamahinga-ā-koe: I whakaitihia te whakamahinga ā-tau o te whatunga hiko o te whare o Zhejiang me te pākahiko 5kW o te rā + 10kWh mai i te 2,800kWh ki te 800kWh (kua penapenahia >RMB 1,500).
- Tārua: Ngā motuhanga hiko i puta mai i te ua i Ūropi i te tau 2024: e rua hāora te pānga o ngā whare whai pākahiko, ki te 18 hāora te pānga.
2. Ahumahi me te Arumoni: Te Whakaiti Utu + Te Whakatutukitanga
- Te whakatau tata ki te tihi o te awaawa: I whiwhi te pūnaha 2MWh o tētahi wheketere o Guangdong i te >RMB 5,000/rā (i penapenahia te RMB 1.8 miriona/tau).
- Te whakahaere i te hiahia: Nā te pūnaha 1.5MWh o tētahi toa hokohoko o Shanghai i whakaiti te whakamahinga hiko mōrahi mai i te 8,000kW ki te 6,500kW (i penapenahia >RMB 120,000/marama i roto i ngā utu taketake).
- Mana tārua: Ka whakakapi i ngā UPS mō ngā pokapū raraunga/hōhipera (tere whakawhiti <0.05s, roa ake te wā whakahaere).
3. Taha-Matiti: Te Heu Tino Pai + Te Whakaurunga Whakahou
- Te whakahaere i te tihi: Nā te pūnaha 1.2GWh a Qinghai Grid i whakaiti te piki me te heke o ngā utu mai i te ±15% ki te ±5% (2024).
- Te mimitinga hou: Nā te pākahiko 500MWh o te pāmu hau o Gansu i whakaiti te tere whakahekenga hiko mai i te 18% ki te 3% (tāpirihia he 200M kWh/tau).
4. Waea Pūkoro o Waho: Mana Kawe + Whakaora
- Te puni: Ngā waeine kawe 500Wh-2kWh me ngā rama hiko/pouaka whakamātao (ka tautokohia e ētahi te utu hiko o te rā).
- Whakaora: Nā ngā waka pūkoro 100kWh-1MWh i whakakaha te awhina rū whenua o Turkey i te tau 2024 mō ngā haora 5,000+.
- Ngā mahi i waho o te whatunga hiko: Ka whakakapi i ngā miihini hiko tīhiera i roto i ngā maina/mara hinu (ka whakaiti i te haruru/te parahanga).
III. Whakamutunga: Te Whakataurite i te Painga me te Horopaki
- Ko te haumaru me te āhuatanga ohorere (ngā pūnaha iti, ngāwari ki te tāuta) te kaupapa matua mō ngā whare.
- Ko te arotahi a ngā kaiwhakamahi ahumahi ki te utu me te whai huatanga (ngā otinga kaha nui, roa te ora).
- Me whai pumau me te urutau (pūhiko whānui-pāmahana, pono-teitei) ngā āhuatanga whatunga/waho.
Mā te whanaketanga o ngā pūhiko totoka/konutai-katote, ka whānui te rokiroki pūngao ki te rokiroki moana me te hononga hauwai. Mō ngā kaiwhakamahi, ko te whakataurite i ngā painga ki ngā hiahia o te horopaki te mea nui hei whakatuwhera i tōna uara.
I Ulipower, e arotahi ana mātou ki ngā pākahiko rokiroki pūngao pāmahana-iti—e hangai ana ki te painga matua o te "whakarerekētanga pāmahana whānui" o ngā pūnaha rokiroki pūngao. Ahakoa e hiahia ana koe ki:
- Ngā pākahiko LiFePO₄ pēke/pēke mō ngā āhuarangi makariri: Kua arotauhia kia mahi pono i te -30℃~60℃, kia mau tonu te kaha ≥80% i te -20℃—he tino pai mō te rokiroki whare o Siberia, te hiko ohorere o waho i te whānuitanga teitei, te tārua ahumahi rānei i te rohe hukapapa.
- Ngā whakaritenga ritenga: Ngā kaha mai i te 1Ah (pūnaha rokiroki kawe o waho) ki te 100Ah+ (ngā pūnaha ahumahi/arumoni iti-ki-waenga), kua whakaritea kia rite ki ō hiahia ngaohiko (hei tauira, ngā tautuhinga whare 10kWh, ngā rokiroki āwhina taha-matao rānei).
Ka whakamahia e ā mātou pākahiko ngā kaha o LiFePO₄—he haumaru teitei (800℃ te pirau wera), he 5,000+ te roa o te huringa—kia ora ai i roto i ngā āhuatanga uaua, kia whakakahangia ai ngā EV rohe makariri, kia rokiroki ai i waho o te whatunga hiko, me te tautoko ahumahi tio.
