Noiʻi no ka hoʻonui ʻana i ka Thermal Runaway o ka Battery Lithium Ion mai ka Unite a i ka Module

Ma muli o ke kiʻekiʻe o ka ikehu o nā pā lithium-ion, ka haʻahaʻa haʻahaʻa haʻahaʻa o nā mea maikaʻi a me nā mea maikaʻi ʻole, a me nā electrolyte electrolyte organik flammable, hiki i nā pā lithium-ion ke pilikia palekana ma lalo o kekahi mau kūlana, e like me nā wela kiʻekiʻe a i ʻole. puhi i ke ahi a pahū.Nui nā kumu no nā pilikia palekana o nā pā lithium-ion, e like me ka pōʻino mechanical, ka pōʻino o ke kaiapuni, ka pōʻino uila, a me ko lākou ponoʻole.ʻOiai ke kumu o nā pilikia palekana o nā pā lithium-ion, ʻo nā pōʻino palekana i hōʻike ʻia e nā pā lithium-ion e hui pū ʻia me nā pōkole o loko a me waho e alakaʻi ana i kahi piʻi nui o ka mahana a i ʻole ke ahi a me ka pahū, ʻo ia hoʻi, ka ka pilikia o ka mahuka wela o na pila lithium-ion.

Me ka hoʻohana nui ʻana o nā pā lithium-ion i ke kahua o nā kaʻa uila amālama ikehu, He nui loa nā modula pākahi i hoʻohana ʻia i nā kaʻa uila.Inā ʻaʻole hiki ke hoʻokuʻu ʻia ka wela i waho o ka module pākahi i ka manawa ma muli o nā kumu hoʻolālā a i ʻole ka hāʻule ʻana o ka ʻōnaehana hoʻoluʻu, hoʻokahi a ʻoi aku paha nā cell i loko o ka module e hana i ka hōʻiliʻili wela.Inā hiki ka wela o ka pākaukau i ka wela o ka holo ʻana, hiki ke hū a ʻā paha ka pākaukau, a i ʻole e pohā ka pā.ʻO ke ʻano holo kaʻa nui o ka ʻōnaehana pākahi holoʻokoʻa i hoʻokumu ʻia e ka holo wela o nā pā lithium-ion ʻo ia ka hoʻonui ʻana i ka holo wela o nā pā lithium-ion.No ka mana nui, ka mana nui o ka lithium-ion modules, ʻoi aku ka nui o nā pilikia palekana.Ma muli o ka hoʻonui ʻia ʻana o ka thermal runaway ma luna o nā modula pākahi lithium-ion nui, paʻakikī loa ke kinai ʻana i ke ahi, e hoʻopiʻi pinepine ai i nā pōʻino a me nā poho waiwai nui, a nui loa ka hopena.

Wahi a nā hopena ho'āʻo, ʻo ka mana wela kikoʻī o kaʻO ka pākaukau lithium ion ternarya ʻo ka pākaukau lithium iron phosphate lithium ion i hoʻohana ʻia he ʻano like.I ka thermal runaway ho'āʻo lōʻihi, ma hope o ka ternary lithium-ion pākahiko module triggered i ka thermal runaway o hoʻokahi pākahi, i ke koena pila ike thermal runaway ma huli, a hoike i kekahi regularity i ka ulu ana o thermal runaway;lithium iron phosphate ʻAʻole hiki ke hoʻonui ʻia ka hoʻonui ʻana i ka wela o ka module pākahiko ion.Ma hope o ka hoʻomaka ʻana i ka holo wela o hoʻokahi pākaukau, ʻaʻole i loaʻa i nā pā i koe ka holo wela.Ma hope o 3 mau hola o ka hoʻomehana ʻana, ʻaʻole i hiki ke holo ʻana i ka wela.Hoʻopau ka pahu lithium ion ternary i ke ahi a ʻaʻa nui i ka wā i pau ʻole ai ka wela, a ʻoi aku ka kiʻekiʻe o ka ikehu i hoʻokuʻu ʻia ma mua o ka pā lithium iron phosphate lithium ion.
