ʻO ke kumukūʻai o kahi waihona pākaukau 10 kwh e pili ana i ke ʻano o ka pākaukau a me ka nui o ka ikehu hiki iā ia ke mālama. He ʻokoʻa nō hoʻi ke kumukūʻai, ma muli o kahi āu e kūʻai ai.
Nui nā ʻano ʻokoʻa like ʻole o nā pākahi lithium-ion i loaʻa ma ka mākeke i kēia lā, me:
Lithium cobalt oxide (LiCoO2) - ʻO kēia ke ʻano maʻamau o ka pākaukau lithium-ion i hoʻohana ʻia i nā mea uila uila. He mea maʻalahi ka hana ʻana a hiki ke mālama i ka nui o ka ikehu ma kahi liʻiliʻi. Eia nō naʻe, maʻa lākou e hoʻohaʻahaʻa koke i ka wā e ʻike ʻia ai i nā wela kiʻekiʻe a i ʻole ke anu nui a pono e mālama pono.
Lithium iron phosphate (LiFePO4) - Hoʻohana pinepine ʻia kēia mau pila i nā kaʻa uila no ka mea he kiʻekiʻe ka ikehu ikaika a hiki ke kū i nā ukana kaumaha me ka hoʻohaʻahaʻa ʻole ʻana e like me nā ʻano ʻē aʻe o nā pā lithium-ion. ʻOi aku ke kumukūʻai ma mua o nā ʻano ʻano ʻē aʻe, akā naʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana me nā mea uila uila e like me laptops a i ʻole kelepona.
Hiki ke kūʻai ʻia kahi pākahi lithium 10kwh mai $3,000 a i $4,000. ʻO kēlā ʻano kumu kūʻai no ka mea he nui nā kumu e pili ana i ke kumukūʻai o kēia ʻano pākaukau.
ʻO ke kumu mua ka maikaʻi o nā mea i hoʻohana ʻia i ka hana ʻana o ka pākaukau. Inā ʻoe e hele ana i kahi huahana kiʻekiʻe loa, e hoʻopau ʻoe i ka uku ʻoi aku no ia mea ma mua o ke kūʻai ʻana i kahi mea kūʻai haʻahaʻa.
ʻO kekahi kumu e pili ana i ke kumukūʻai, ʻo ia ka nui o nā ʻaʻa i hoʻokomo ʻia i hoʻokahi kūʻai: Inā makemake ʻoe e kūʻai i hoʻokahi a ʻelua paha mau ʻeke, e ʻoi aku ke kumukūʻai ma mua o ke kūʻai ʻana i ka nui.
ʻO ka mea hope loa, aia kekahi mau mea ʻē aʻe e pili ana i ke kumukūʻai holoʻokoʻa o nā pā lithium-ion, e komo pū ana me nā ʻano palapala hōʻoia a inā i hana ʻia e kekahi mea hana paʻa i hala no nā makahiki.
