ʻO ke kumukūʻai o kahi waihona pila 10 kwh e pili ana i ke ʻano o ka pila a me ka nui o ka ikehu hiki iā ia ke mālama. ʻOkoʻa nō hoʻi ke kumukūʻai, ma muli o kahi āu e kūʻai ai.
Nui nā ʻano pākahi lithium-ion like ʻole i loaʻa ma ka mākeke i kēia lā, e like me:
ʻO Lithium cobalt oxide (LiCoO2) - ʻO kēia ke ʻano maʻamau o ka pākahi lithium-ion i hoʻohana ʻia i nā mea uila mea kūʻai. He mea kūʻai ʻole ke kumukūʻai o ka hana ʻana a hiki ke mālama i ka nui o ka ikehu ma kahi liʻiliʻi. Eia nō naʻe, e pala koke lākou ke hōʻike ʻia i nā mahana kiʻekiʻe a i ʻole ke anu loa a pono e mālama pono ʻia.
ʻO ka Lithium iron phosphate (LiFePO4) - Hoʻohana pinepine ʻia kēia mau pila i nā kaʻa uila no ka mea he kiʻekiʻe ko lākou ikehu a hiki ke kū i nā ukana kaumaha me ka ʻole o ka hōʻino koke ʻana e like me nā ʻano pila lithium-ion ʻē aʻe. ʻOi aku ke kumukūʻai ma mua o nā ʻano ʻē aʻe, akā naʻe, ʻo ia ka mea e hoʻolilo ai iā lākou i mea kaulana ʻole no ka hoʻohana ʻana me nā mea uila e like me nā kamepiula lawe lima a i ʻole nā kelepona paʻalima.
ʻO ke kumukūʻai o kahi pākahiko lithium 10kwh mai $3,000 a i $4,000. ʻO kēlā pae kumukūʻai no ka mea he nui nā kumu e hiki ke hoʻopilikia i ke kumukūʻai o kēia ʻano pākahiko.
ʻO ke kumu mua, ʻo ia ka maikaʻi o nā mea i hoʻohana ʻia i ke kūkulu ʻana o ka pila. Inā ʻoe e ʻimi nei i kahi huahana kiʻekiʻe loa, e uku nui ʻoe no ia ma mua o ke kūʻai ʻana i kahi mea emi ke kumu kūʻai.
ʻO kekahi kumu e hoʻopilikia ai i ke kumukūʻai, ʻo ia ka nui o nā pila i hoʻokomo ʻia i hoʻokahi kūʻai: Inā makemake ʻoe e kūʻai i hoʻokahi a ʻelua paha mau pila, e ʻoi aku ke kumukūʻai ma mua o ke kūʻai nui ʻana iā lākou.
ʻO ka mea hope loa, aia kekahi mau kumu ʻē aʻe e hoʻopilikia ai i ke kumukūʻai holoʻokoʻa o nā pila lithium-ion, me ka loaʻa ʻana o kekahi ʻano palapala hoʻokō a inā hana ʻia e kahi mea hana i hoʻokumu ʻia no nā makahiki.
