1. Ike uilamānoanoa

ʻO ka hoʻomanawanui kekahi o nā hana koʻikoʻi o nā kaʻa uila, a ʻo ka lawe ʻana i nā ʻoniʻoni hou aʻe i kahi palena palena ʻo ia ke ala pololei loa e hoʻonui ai i ka mile mile.No laila, ʻo kahi papa kuhikuhi nui no ka loiloi ʻana i ka hana ʻana o ka pākaukau, ʻo ia ka ikehu uila, ʻo ia wale nō ka ikehu uila i loko o ka ʻāpana pākahi a i ʻole ka leo, ma lalo o ka leo like a i ʻole ke kaumaha, ʻO ke kiʻekiʻe o ka ikehu, ʻoi aku ka nui o ka ikehu uila e hāʻawi ʻia. , a ʻo ka lōʻihi o ka hoʻomanawanui he ʻano;Ma ka pae mana like, ʻoi aku ka kiʻekiʻe o ka ikehu o ka pākaukau, ʻoi aku ka māmā o ke kaumaha o ka pā.Ua ʻike mākou he hopena nui ke kaumaha i ka hoʻohana ʻana i ka ikehu.No laila, ʻaʻohe mea mai kahi o ka manaʻo, ʻo ka hoʻonui ʻana i ka nui o ka ikehu o ka pākaukau e like me ka hoʻonui ʻana i ka hoʻomanawanui o ke kaʻa.
Mai ka ʻenehana o kēia manawa, ʻo ka nui o ka ikehu o ka pākahi lithium ternary ma ke ʻano he 200wh / kg, hiki ke hiki i 300wh / kg i ka wā e hiki mai ana;I kēia manawa, lele ka lithium iron phosphate pākahi ma 100 ~ 110wh / kg, a hiki i kekahi ke hiki i 130 ~ 150wh / kg.Ua hoʻokuʻu ʻo BYD i kahi hanauna hou o ka lithium iron phosphate pākahiko "blade battery" i ka manawa.ʻO kāna "volume specific energy density" he 50% kiʻekiʻe aʻe ma mua o ka pākaukau lithium iron phosphate kuʻuna, akā paʻakikī hoʻi e uhaʻi i ka 200wh / kg.

2. Kū'ē wela kiʻekiʻe

ʻO ka palekana kekahi o nā pilikia koʻikoʻi o nā kaʻa uila, a ʻo ka palekana o nā pihi ka mea nui o nā kaʻa uila.ʻO ka pākaukau lithium ternary ka mea maʻalahi i ka mahana a e hoʻoheheʻe ʻia ma kahi o 300 degere, aʻo ka mea lithium hao phosphate ma kahi o 800 degere.Eia kekahi, ʻoi aku ka ikaika o ka hopena kemika o nā mea lithium ternary, kahi e hoʻokuʻu ai i nā moleke oxygen, a e puhi koke ka electrolyte ma lalo o ka hana o ka wela kiʻekiʻe.No laila, ʻoi aku ka kiʻekiʻe o nā koi o ka bateria lithium ternary no ka ʻōnaehana BMS, a pono nā mea pale anti overtemperature a me ka ʻōnaehana hoʻokele pākaukau e pale i ka palekana o ka pā.

3. Haʻahaʻa wela adaptability

ʻO ka attenuation o ka mileage kaʻa uila i ka hoʻoilo he mea maʻi poʻo no nā ʻoihana kaʻa.ʻO ka maʻamau, ʻaʻole haʻahaʻa ka haʻahaʻa haʻahaʻa haʻahaʻa o ka lithium iron phosphate ma lalo o - 20 ℃, aʻo ka haʻahaʻa haʻahaʻa o ka lithium ternary hiki ke emi ma lalo o - 30 ℃.Ma lalo o ka haʻahaʻa haʻahaʻa haʻahaʻa like, ʻoi aku ka kiʻekiʻe o ka lithium ternary ma mua o ka lithium iron phosphate.No ka laʻana, ma ka liʻiliʻi o 20 ° C, hiki ke hoʻokuʻu i ka pākahi lithium ternary ma kahi o 80% o ka hiki, ʻO ka lithium hao phosphate hiki ke hoʻokuʻu wale ma kahi o 50% o kona hiki.Eia kekahi, ʻoi aku ka kiʻekiʻe o ke kahua hoʻokuʻu o ka pā lithium ternary i ka haʻahaʻa haʻahaʻa haʻahaʻa ma mua o ka pā lithium iron phosphate, hiki ke hāʻawi i ka pāʻani nui i ka hiki o ka moto a me ka mana ʻoi aku ka maikaʻi.

4. Hoʻokō i ka hana

ʻAʻohe ʻokoʻa ʻokoʻa ma waena o ka mana hoʻopaʻa paʻa mau o kēia manawa / ka nui o ka nui o ka nui o ka pākahi lithium ternary a me ka lithium iron phosphate pākaukau i ka wā e hoʻopiʻi ʻole ai ma mua o 10 C. i ka wā e hoʻopiʻi ana i ka helu ma luna o 10 C, ka mana hoʻopiʻi mau o kēia manawa / piha piha. liʻiliʻi ka lakio o ka pā lithium hao phosphate.ʻO ka ʻoi aku ka nui o ka hoʻopiʻi ʻana, ʻoi aku ka maopopo o ka ʻokoʻa ma waena o ka mana o ka hoʻouka ʻana i kēia manawa / ka nui o ka nui o ka mana a me ka pākaukau ternary, pili nui kēia i ka hoʻololi liʻiliʻi liʻiliʻi o ka lithium iron phosphate ma 30% ~ 80% SOC.
5. Ke ola pōʻaiapuni
ʻO ka hoʻemi ʻana i ka mana o ka pākaukau kekahi wahi ʻeha o nā kaʻa uila.ʻOi aku ka nui o ka nui o ka uku piha a me ka hoʻokuʻu ʻana o ka pākaukau lithium iron phosphate ma mua o 3000, ʻoiai ʻoi aku ka pōkole o ke ola lawelawe o ka pākahi lithium ternary ma mua o ka pā lithium iron phosphate.Inā ʻoi aku ka nui o ka helu o ka uku piha a me ka hoʻokuʻu ʻana ma mua o 2000, e hoʻomaka ana ka attenuation.
6. Koki hana
ʻO nā mea nickel a me ka cobalt e pono ai no nā ʻāpana lithium ternary he mau metala makamae, ʻoiai ʻaʻole i loaʻa i nā pākaukau lithium iron phosphate nā mea metala makamae, no laila ke kiʻekiʻe ke kumu kūʻai o nā pā lithium ternary.

I ka huina: loaʻa i ka pākaukau lithium ternary a i ʻole lithium iron phosphate ko lākou pono ponoʻī a me nā hemahema.I kēia manawa, loaʻa iā lākou nā ʻelele like ʻole.Ke wāwahi nei nā mea hana i nā palena ʻenehana kūpono a koho wale i ka pākaukau o nā mea pili e like me nā pono kikoʻī
