ʻO kekahi o nā kemika i loaʻa kokeNā pila Lithiumʻo ia ke ʻano Lithium Iron Phosphate (LiFePO4). ʻO kēia no ka mea ua ʻike ʻia lākou ʻo ia ka mea palekana loa o nā ʻano Lithium a he liʻiliʻi loa a māmā hoʻi i ka hoʻohālikelike ʻia me nā pila waikawa kēpau o ka mana like.

ʻO kahi makemake maʻamau i kēia mau lā, ʻo ia ke pani i kahi pila waikawa kēpau meLiFePO4i loko o kahi ʻōnaehana i loaʻa mua kahi ʻōnaehana hoʻouka i kūkulu ʻia. ʻO kahi laʻana o kekahi he ʻōnaehana hoʻihoʻi pila sump pump. No ka mea hiki i nā pila no ia ʻano noi ke noho i ka nui o ka leo i loko o kahi ākea paʻa, ʻo ke ʻano o ka loaʻa ʻana o kahi panakō pila ʻoi aku ka liʻiliʻi.

Eia nā mea e pono ai ke ʻike:

★ʻO nā pila waikawa kēpau 12 V i hana ʻia me 6 mau cell. I mea e hoʻopiʻi pono ai kēia mau cell pākahi, pono lākou i 2.35 volts e hoʻopiʻi piha ai. ʻO kēia ka mea e pono ai ke ana uila holoʻokoʻa no ka mea hoʻoili uila he 2.35 x 6 = 14.1V

★ʻEhā wale nō pūnaewele o nā pila 12V LiFePO4. I mea e hoʻopiha piha ai, pono i kēlā mau pūnaewele pākahi he 3.65V volts e hoʻopiha piha ai. ʻO kēia ka mea e pono ai ke ana uila holoʻokoʻa o ka mea hoʻoili he 3.65 x 4 = 14.6V

Hiki ke ʻike ʻia he pono ke anakahi uila kiʻekiʻe iki e hoʻopiha piha i ka pākahiko Lithium. No laila, inā e hoʻololi wale kekahi i ka pākahiko waikawa kēpau me ka lithium, e waiho ana i nā mea ʻē aʻe e like me ia, hiki ke manaʻo ʻia ka hoʻopiha piha ʻole ʻana no ka pākahiko Lithium - ma waena o 70%-80% o ka hoʻopiha piha. No kekahi mau noi, ua lawa paha kēia, ʻoiai inā ʻoi aku ka nui o ka ikehu o nā pākahiko pani ma mua o ka pākahiko waikawa kēpau mua. ʻO ka hōʻemi ʻana i ka nui o ka pākahiko e hāʻawi i ka mālama nui ʻana i ka wahi a ʻo ka hana ʻana ma lalo o 80% o ka nui o ka hiki ke hoʻonui i ke ola o ka pākahiko.
