Mō ngā kaiwhakahaere papa korowha, ngā kaiwhakahaere o ngā wāhi hararei, me ngā kaipupuri waka korowha tūmataiti puta noa i te US, te Tonga-mā-rāwhiti o Āhia, me Ahitereiria, ko te pākahiko te toa ngaro o ngā mahi o ia rā. He maha ngā wā ka hē ngā pākahiko waikawa-mata tuku iho—ka huri pinepine, ka pakaru nā te huarere, ka nui hoki ngā utu tiaki. Heoi anō, kua hurihia e ngā pākahiko Rino Phosphate (LiFePO4) te pukapuka ture, ka huri i ngā uauatanga mahi hei whai huatanga maeneene. Anei te huarahi e whakapai ake ai i te mahi o te waka korowha puta noa i te ao.
He aha te mea e huri ai ngā pākahiko LiFePO4 i te kēmu mō ngā kaata korowha?
Ehara i te mea ko te "hangarau hou" anake te kaupapa o te neke ki te LiFePO4—engari ko te whakaoti rapanga motuhake e pāngia ana e ngā waka korowha. E whā ngā painga nui o ēnei pākahiko:
1. Te Roa o te Ora, Ngā Huringa Whakakapinga Iti
Ka tukuna e te pākahiko LiFePO4 e tiakina pai ana4,000+ huringa utu hohonu(he rite ki te 6–10 tau o te whakamahinga), ka whakanekehia te roa o te ora o ngā pākahiko waikawa-mata kounga teitei. Mō tētahi papa korowha e whakahaere ana i te 30 ngā kāreti i ia rā, ko te tikanga me whakakapi ngā pākahiko kotahi noa i te tekau tau, kaua i ia 2–3 tau. Hei tauira, he wāhi hararei rahi-waenga i Florida: i muri i te huri ki te LiFePO4, ka tapahia e rātou ngā utu whakakapinga pākahiko mā te 65% i roto i te 5 tau—kāore he wā kore e tumanakohia mai i ngā pākahiko mate i waenganui o te rauna.
2. Te Mana Pūmau i ngā Pāmahana Tino Nui
He rerekē ki ngā pākahiko waikawa-mata, e ngaro ana te kaha o te 30–50% i te wera 35°C+ (95°F+) i te pāmahana rānei, e tio ana rānei i raro i te 0°C (32°F), ka tupu pai a LiFePO4 i ngā wāhi tino kino. Ka mahi pono mai i-20°C ki te 55°C (-4°F ki te 131°F), e pupuri ana i te 80% te kaha i te 45°C (113°F) me te 75% i te -10°C (14°F). He mea nui tēnei mō ngā papa tākaro i ngā koraha o Arizona (kei reira te pāmahana raumati e eke ana ki te 40°C) i Hokkaido rānei o Hapani (me te hukarere hotoke), kia wātea ai ngā kāreti puta noa i te tau.
3. Te Whai Hua o te Pūngao e Whakaiti ana i ngā Utu Whakahaere
E whakamanamana ana ngā pākahiko LiFePO499% te pai o te utu—ki te whakataurite ki te 75–80% mō te waikawa mata—arā, he iti ake te pūngao e maumauria ana i te wā e utu ana. E 5.76 kWh noa iho te whakamahinga o te kete LiFePO4 48V 120Ah hei utu katoa, ko te 7.2 kWh ia kete waikawa mata. Mō te 20 ngā kāreti e utua ana i ia rā, he penapena tēnā o te 10,512 kWh ia tau—he nui hei whakakaha i te 1 whare toharite o US mō ngā marama 12. Hei tāpiri, ko te iti o te tere tuku-ake-ake (2–3% ia marama, ki te 10–15% mō te waikawa mata) ko te tikanga kāore he "pāhiko mate" i muri i te kore whakamahi i te mutunga wiki.
4. Hoahoa Kiato, Tāutanga Ngāwari
He 40–50% te iti ake o ngā pākahiko LiFePO4, ā, he mama ake i ngā pākahiko rite ki te waikawa mata-ara. E 25 pauna noa iho te taumaha o te kete LiFePO4 36V, ki te 55 pauna mō te waikawa mata-ara—ka whakaitihia te taumaha o te kāreti mā te 15–20%. Ehara i te mea ka whakamama noa i te taumahatanga ki ngā motuka me ngā parai (ka whakaroa ake i te roa o te wā e whakamahia ana te kāreti mā te 20%) engari ka uru hoki ki ngā wāhi kuiti: ka taea e ngā kāreti korowha tawhito (pēnei i ngā tauira Club Car o ngā tau 1980) me ngā kāreti waka ritenga mō ngā ara whaiti te whakapai ake inaianei me te kore e whakarerekē i ō rātou anga.
Ngā Otinga LiFePO4 Whakaritea mō ngā Mahi Korowha Kanorau
He motuhake ngā matea o ia whare korowha—ā, ka urutau ngā pākahiko LiFePO4 kia ōrite ki:
1. Ngā Rōpū o te Whare Hōtēra me te Papa Korowha e Waka Tere ana
Mō ngā wāhi hararei e mahi tahi ana ngā kaata hei waka kawe manuhiri (mai i ngā papa waka ki ngā whare karapu) ā, ka rere ngā papa korowha mai i te ata ki te pō,ngā kete LiFePO4 kaha-teitei (150–200Ah)He tino pai. Ka taea e rātou te toro atu ki te 60–80 km mō ia utunga—he nui mō te rua rauna korowha katoa me te 5+ haerenga waka tere—kāore he utu anō i waenganui o te rā. Ka tukuna anō hoki e ngā kaihanga matua ngā hoahoa "whakawhiti wera": ka taea te whakawhiti i te pākahiko kua pau ki tētahi pākahiko kua utua katoatia i roto i te 2 meneti, kia mau tonu ai te haere o ngā waka i ngā wā pīrahi.
2. Ngā Kāreti Whaiaro me ngā Kāreti Whakangahau Kiato
Ka whai hua ngā kaipupuri tūmataiti, ngā papa tākaro iti rānei me ngā kāreti 5–10ngā kete LiFePO4 māmā 36V/48V (80–100Ah). Ka uru ēnei pākahiko ki ngā wāhanga pākahiko paerewa, kāore e hiahiatia he whakawhiti waea, ā, ka utua i roto i te 1.5–2 hāora (he tino pai mō te utu i te pō). I kōrero tētahi rangatira tūmataiti i California: "I mua, e 8 hāora taku utu i taku pākahiko waikawa-mata—ināianei ka mono ahau i muri i te hurihanga, ā, kua kī i te tina."
3. Te Haumaru me te Whakatutukitanga ā-Ao Ka Taea e Koe te Whakawhirinaki
Ka tutuki ngā pākahiko kāreti korowha LiFePO4 katoaUL 2271 (mō ngā waka hiko māmā)meIEC 62133ngā paerewa, me te whakarite kia ātete ki te wera nui, ki ngā ara iahiko poto, me ngā kino tinana. Kāore hoki i te paitini (kāore he mata, he waikawa rānei) ā, ka taea te hangarua katoa—e hangai ana ki ngā aratohu "Sustainable Golf Facility" a te US EPA me ngā ture REACH a te EU. Mō ngā wāhi hararei ao whānui, ka māmā ake te tuku kaipuke whakawhiti-rohe mā tēnei hanganga ture (kāore e hiahiatia he whakaaetanga rauemi morearea).
Te Painga o te Utu Katoa o te Mana Whakahaere (TCO)
He pono: He nui ake te utu tīmatanga mō ngā pākahiko LiFePO4 (ko te tikanga he 1,800–3,000 mō te kete 48V, ki te 700–900 mō te waikawa mata). Engari he rerekē te kōrero a tā rātou TCO—me wehewehe tātou i tētahi whakatauritenga 5-tau mō tētahi kahui waka 10-kare:
| Kāwai Utu | Ngā Pūhiko LiFePO4 | Ngā Pūhiko Waikawa-Mata |
| Te utu o mua (10 ngā kete) | $22,000 | $8,000 |
| Te Utu Whakakapinga (5 tau) | $0 (kāore he whakakapinga) | $16,000 (2 ngā huinga) |
| Te Utu Pūngao (ā-tau) | $520 | $680 |
| Mahi Tiaki (ā-tau) | $300 (he haki ā-hauwhā) | $1,200 (whakakī wai, horoi) |
| Tapeke 5-Tau | $25,100 | $29,400 |
I roto i ngā tau e 5, ka penapenahia e te LiFePO4 te 4,300—ā, ka whānui haere te āputa mō ngā waka nunui. Mō te huarahi 50-kāreti, ka piki ake ngā penapena 5-tau ki te 21,500.
Te Tiaki Māmā hei Whakanui i te Ora o te Pūhiko
He iti noa te kaha e hiahiatia ana hei whakamahi i tō pākahiko LiFePO4 kia tino whai hua ai:
- Utu atamaiWhakamahia he rihi motuhake ki te LiFePO4 (14.6V mō ngā pūtau 12V) hei karo i te kino o te BMS—kaua rawa e whakamahia he rihi waikawa-mata.
- Penapena ki te taha matauKi te kore e whakamahia mō te 1+ marama, rongoatia ki te 40–60% te kaha ki te wāhi maroke, hauhautanga (10–25°C).
- Horoia mārireHoroia ngā pito o te pākahiko ki te kakahu maroke (kaua he wai, he matū rānei—kua hiritia te LiFePO4).
- Aroturuki BMSHe maha ngā kete he tohu LED mō te taumata utu me ngā hapa—ka aro tonu ki ngā rama e kimo ana (hei tauira, ko te kimo whero he tohu ia he nui rawa te iahiko).
Whakatau: LiFePO4 = Ngā Mahi Korowha Atamai, Kakariki Ake
Ehara ngā pākahiko LiFePO4 i te mea he whakapai ake noa iho—he haumitanga roa ki te whai huatanga, te pono, me te pumau. Mō ngā papa korowha e whai ana ki te whakaiti i te wā kore mahi, mō ngā wāhi hararei e whakatairanga ana i ngā wheako manuhiri, mō ngā rangatira tūmataiti rānei e rapu ana i te whakamahinga kore raruraru, ka tukuna e rātou he uara e kore e taea te rite ki te waikawa mata.
I Ulipower, ka neke atu mātou i tēnei mahi: he mea hanga motuhake ā mātou pākahiko waka korowha LiFePO4 mō tō āhuarangi me tō whakamahinga. Mō ngā papa koraha, ka tāpirihia e mātou he anga ātete wera; mō ngā wāhi hararei maunga, ka whakanuia e mātou te kaha pāmahana iti (ka pupuri i te 75% i te -15°C); mō ngā waka tere, ka tāpirihia e mātou he aroturuki GPS kua hangaia (hei aroturuki i ngā taumata utu mai i tawhiti). Ko ā mātou kete katoa he tiwhikete UL 2271, ā, he whakamana 5-tau te tautoko. Kei te rite koe ki te whakarerekē i ngā mahi o tō waka korowha? Whakapā mai ki a mātou ki te hoahoa i tētahi otinga pākahiko e rite ana ki ō hiahia—ka mihi atu tō tahua me tō tīma ki a koe.
