He aha ka pākahiko LiFePO4?
ʻO ka pākahiko LiFePO4 kahi ʻano pākahiko lithium-ion e hoʻohana ana i ka lithium hao phosphate (LiFePO4) no kāna mea electrode maikaʻi. Ua kaulana kēia pākahiko no kona palekana kiʻekiʻe a me ke kūpaʻa, ke kūpaʻa ʻana i nā mahana kiʻekiʻe, a me ka hana pōʻaiapuni maikaʻi loa.
He aha ke ola o kahi pākahiko LiFePO4?
ʻO ka maʻamau, he ola pōʻaiapuni ko nā pila lead-acid ma kahi o 300 mau pōʻaiapuni, me ka nui o 500 mau pōʻaiapuni. I ka hoʻohālikelike ʻana, ʻoi aku ka nui o ke ola pōʻaiapuni o nā pila mana LiFePO4 ma mua o 2000 mau pōʻaiapuni. ʻO ka maʻamau, ʻo ka lōʻihi o nā pila lead-acid ma kahi o 1 a 1.5 mau makahiki, i wehewehe ʻia he "mea hou no ka hapalua makahiki, mea kahiko no ka hapalua makahiki, a mālama ʻia no kekahi hapalua makahiki." Ma lalo o nā kūlana like, he 7 a 8 mau makahiki ke ola o kahi pākahi LiFePO4.
ʻO ka maʻamau, ʻo ka lōʻihi o ke ola o nā pākahiko LiFePO4 ma kahi o 8 mau makahiki; akā naʻe, i nā ʻāina mehana, hiki i ko lākou ola ke ʻoi aku ma mua o 8 mau makahiki. ʻOi aku ke ola o kahi pākahiko LiFePO4 ma mua o 2,000 mau pōʻaiapuni hoʻoiho-hoʻokuʻu, ʻo ia hoʻi, ʻoiai me ka hoʻouka ʻana i kēlā me kēia lā, hiki ke mau ma mua o ʻelima mau makahiki. No ka hoʻohana maʻamau o ka hale, me ka hoʻouka ʻana i kēlā me kēia ʻekolu lā, hiki ke mau ma kahi o ʻewalu mau makahiki. Ma muli o ka hana haʻahaʻa haʻahaʻa, ʻoi aku ka lōʻihi o ke ola o nā pākahiko LiFePO4 ma nā wahi mehana.
Hiki i ke ola lawelawe o kahi pākahiko LiFePO4 ke hiki aku ma kahi o 5,000 mau pōʻaiapuni, akā he mea nui e hoʻomaopopo he helu kikoʻī ko kēlā me kēia pākahiko o nā pōʻaiapuni hoʻouka a hoʻokuʻu (e laʻa, 1,000 mau pōʻaiapuni). Inā ʻoi aku kēia helu ma mua o kēlā, e emi ana ka hana o ka pākahiko. Hoʻopilikia nui ka hoʻokuʻu piha ʻana i ke ola o ka pākahiko, no laila he mea nui e pale aku i ka hoʻokuʻu nui ʻana.
Nā Pōmaikaʻi o nā Pākahi LiFePO4 i hoʻohālikelike ʻia me nā Pākahi Lead-Acid:
Ka Mana Kiʻekiʻe: Hiki i nā pūnaewele LiFePO4 ke loaʻa mai 5Ah a 1000Ah (1Ah = 1000mAh), ʻoiai ʻo nā pila kēpau-ʻakika maʻamau mai 100Ah a 150Ah no kēlā me kēia pūnaewele 2V, me ka palena o ka loli.
Kaumaha Māmā: ʻO kahi pākahiko LiFePO4 o ka mana like he ʻelua hapakolu ka nui a hoʻokahi hapakolu ke kaumaha o kahi pākahiko kēpau-ʻakika.
Ka Mana Hoʻouka Wikiwiki Ikaika: Hiki i ke au hoʻomaka o kahi pākahiko LiFePO4 ke hiki i 2C, e hiki ai ke hoʻouka wikiwiki. I ka hoʻohālikelike ʻana, pono nā pākahiko kēpau-ʻakika i kahi au ma waena o 0.1C a me 0.2C, e paʻakikī ai ka hoʻouka wikiwiki.
Palekana Kaiapuni: Loaʻa i nā pila kēpau-ʻakika ka nui o ke kēpau, kahi e hana ai i nā ʻōpala weliweli. Ma ka ʻaoʻao ʻē aʻe, ʻaʻohe metala kaumaha i nā ʻeke pila LiFePO4 a ʻaʻole ia e hoʻohaumia i ka wā o ka hana ʻana a me ka hoʻohana ʻana.
Kumukūʻai Kūpono: ʻOiai ʻoi aku ka liʻiliʻi o ke kumukūʻai o nā pila kēpau-ʻakika ma muli o ko lākou kumukūʻai mea, ua hōʻike ʻia nā pila LiFePO4 he ʻoi aku ka hoʻokele waiwai i ka wā lōʻihi, e noʻonoʻo ana i ko lākou ola lawelawe lōʻihi a me nā koi mālama haʻahaʻa. Hōʻike nā noi hana he ʻoi aku ka liʻiliʻi o ke kumukūʻai o nā pila LiFePO4 ma mua o ʻehā manawa ma mua o nā pila kēpau-ʻakika.
