Pono nā pila lithium i kahi ʻōnaehana hoʻokele (BMS)?

Hiki ke hoʻohui ʻia kekahi mau ʻeke lithium i ka pūʻulu e hana i kahi pākaukau, hiki ke hāʻawi i ka mana i nā ukana like ʻole a hiki ke hoʻopiʻi maʻamau me kahi loina pili. ʻAʻole pono nā ʻoihana lithium i kekahi ʻōnaehana hoʻokele pākaukau (BMS) e hoʻouka a hoʻokuʻu. No laila, no ke aha e hoʻohui ai nā pākahi lithium āpau i ka mākeke BMS? ʻO ka pane ka palekana a me ka lōʻihi.

Hoʻohana ʻia ka ʻōnaehana hoʻokele pākaukau ʻo BMS (Battery Management System) e nānā a hoʻokele i ka hoʻouka ʻana a me ka hoʻokuʻu ʻana i nā ʻenekini hiki ke hoʻouka hou ʻia. ʻO ka hana koʻikoʻi o kahi ʻōnaehana hoʻokele pākaukau lithium (BMS) ʻo ia ka hōʻoia ʻana i ka noho ʻana o nā pā i loko o nā palena hana palekana a e hana koke i ka hana inā hoʻomaka kekahi pākahi i nā palena. Inā ʻike ka BMS i ka haʻahaʻa haʻahaʻa o ka uila, e hoʻokaʻawale ia i ka ukana, a inā kiʻekiʻe ka uila, e hoʻokaʻawale ia i ka charger. E nānā pū ʻo ia i kēlā me kēia cell i loko o ka pūʻolo i ka volta like a hoʻemi i ka volta i ʻoi aku ka kiʻekiʻe ma mua o nā cell ʻē aʻe. ʻO kēia ka mea e hōʻoia ai ʻaʻole hiki i ka pākaukau ke hiki i nā voltage kiʻekiʻe a haʻahaʻa pahaʻo ia ke kumu o ka puhi ʻana i nā pahu lithium a mākou e ʻike ai ma ka nūhou. Hiki iā ia ke nānā i ka wela o ka pākaukau a hoʻokaʻawale i ka pūʻolo pila ma mua o ka wela loa ʻana i ke ahi. No laila, ʻo ka ʻōnaehana hoʻokele pākaukau ʻo BMS e ʻae i ka pale ʻana i ka pākaukau ma mua o ka hilinaʻi wale ʻana i kahi charger maikaʻi a i ʻole ka hana hoʻohana pololei.

No ke aha don't pono i na kinikini alakai-acid i ka nenae hooponopono pila? ʻAʻole hiki ke ʻā ʻia ka hana ʻana o nā pākī lead-acid, ʻoi aku ka liʻiliʻi o ke ahi inā pilikia ka hoʻouka ʻana a i ʻole ka hoʻokuʻu ʻana. Akā ʻo ke kumu nui e pili ana i ka hana ʻana o ka pākaukau ke hoʻopiha piha ʻia. Hoʻokumu pū ʻia nā ʻakika Lead-acid i nā cell i hoʻopili ʻia ma ka moʻo; Inā ʻoi aku ka nui o ka uku o kekahi cell ma mua o nā cell ʻē aʻe, e hoʻokuʻu wale ia i kēia manawa a hiki i ka piha ʻana o nā cell ʻē aʻe, me ka mālama ʻana i ka volta kūpono, a pēlā aku. Ma kēia ʻano, ʻo nā pākaʻi lead-acid e "kaulike iā lākou iho" i kā lākou uku.

ʻOkoʻa nā ʻōhua lithium. ʻO ka electrode maikaʻi o nā pā lithium rechargeable ka hapa nui o nā mea lithium ion. ʻO kāna kumu hana e hoʻoholo ai i ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana, e holo hou nā electrons lithium i nā ʻaoʻao ʻelua o nā electrodes maikaʻi a maikaʻi ʻole. Inā ʻae ʻia ke kiʻekiʻe o ka volta o ke kelepona hoʻokahi ma mua o 4.25v (koe naʻe nā pā lithium kiʻekiʻe-voltage), hiki ke hāʻule ka anode microporous structure, ulu ka mea aniani paʻakikī a hoʻoulu i kahi pōkole pōkole, a laila piʻi ka mahana. hikiwawe, a hiki i ke ahi. Ke hoʻopiha piha ʻia ka pākaukau lithium, piʻi koke ka uila a hiki koke i nā pae weliweli. Inā ʻoi aku ka kiʻekiʻe o ka volta o kekahi kelepona i loko o ka pā pākaukau ma mua o ka nui o nā cell ʻē aʻe, e hiki mua kēia kelepona i ka volta pōʻino i ka wā o ke kaʻina hana. I kēia manawa, ʻaʻole i hōʻea ka volta holoʻokoʻa o ka pā pākaukau i ka waiwai piha, a ʻaʻole e pau ke kau ʻana i ke kau ʻana. . No laila, ʻo nā pūnaewele e hōʻea mua i nā voltage pōʻino e hoʻopilikia i ka palekana. No laila, ʻaʻole lawa ka hoʻomalu ʻana a me ka nānā ʻana i ka nui o ka volta o ka pā pākaukau no nā kemika-based lithium. Pono ka BMS e nānā i ka volta o kēlā me kēia cell e hana ana i ka pūʻolo pila.

No laila, no ka hōʻoia ʻana i ka palekana a me ka lōʻihi o ka lawelawe ʻana o nā pā uila lithium, pono pono kahi ʻōnaehana hoʻokele pono a hilinaʻi BMS.
