I ka hoʻomaka mua ʻana o ka mākeke kaʻa uila maʻemaʻe, ʻo nā pā uila lithium iron phosphate ion he mau ʻona nui. Eia nō naʻe, me ka hoʻomohala ʻana o ka pā uila lithium-ion mana, ua hoʻololi mālie ka pākaukau ʻekolu-dimensional i ka pā hao lithium iron. Pono ia no ka pākaukau lithium iron phosphate ion i hoʻohālikelike ʻia me ka ternary lithium ion battery, haʻahaʻa ka ikehu.

I ka hoʻomaka ʻana o ka pā uila lithium-ion, ʻo 100Wh / kg ka ikehu o ka ikehu o ka lithium iron phosphate ion, a hiki i ka 140Wh / kg a ʻoi aku ka nui o ka ikehu o ka ternary lithium ion pack. Me ke ala hou ʻana o ke kaʻa uila liʻiliʻi, me ke kumukūʻai kiʻekiʻe o nā kaʻa uila maʻemaʻe, ʻike ʻia ka ʻokoʻa ma mua o nā kumu hoʻohālike wahie. ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a ʻaʻole maikaʻi ka pākaukau lithium iron phosphate ion pōkole i ke ola pākaukau.

Eia kekahi, ua like ka hana anti-low temperature o ka lithium iron phosphate ion battery a me ka hoʻouka ʻana i ka hana ma mua o ka ternary lithium ion battery. Ma lalo o nā kūlana anu hoʻoilo, e piʻi ka attenuation o nā pā hao hao lithium ma mua o 50%, i hui pū ʻia me ka hana lohi ʻana, e hōʻemi loa i ka pono o ka pass. No laila, ʻoi aku ka maikaʻi o ka ikehu, a ʻoi aku ka ikaika o ka pā uila lithium-ion ʻekolu-yuan e ʻimi ʻia e ka ʻoihana kaʻa.

Me ka hoʻomohala ʻana o ka mākeke, ʻoi aku ka nui o nā hiʻohiʻona o ke ola pākaukau o NEDC ma mua o 600km. Eia naʻe, ʻaʻole pilikia ka pākaukau lithium-ion ʻekolu. ʻOiai ʻoi aku ka maikaʻi o ka ikaika o ka ikehu a me ka hoʻopiʻi ʻana i ka hana, ʻoi aku ka haʻahaʻa ma mua o ka lithium iron phosphate ion battery ma ke ola pōʻai a me ke ola pōʻai.

Hoʻohana paʻa ʻia ka pahu lithium-ion ternary e ka electrode maikaʻi, kahi mea maikaʻi o ka lithium nickel-watery oxynumide a i ʻole nickel-cobalt-aluminate, makemake ʻia e hoʻokumu ʻia ma ka paʻakai nickel, ka paʻakai cobalt, a me nā paʻakai manganese. ʻO ka mea kobalt i loko o kēia mau mea electrode maikaʻi no nā metala makamae. Wahi a ka ʻikepili o ka pūnaewele pili, ʻo nā kumu kūʻai ʻo cobalt metal reference ʻo 277,500 yuan / ton, a me ka hōʻemi ʻana o nā mea, ke ulu mau nei ke kumukūʻai.

I kēia manawa, he 0.85-1 yuan / WH ke kumu kūʻai o ka pākahi lithium-ion ʻekolu; ʻO ke kumukūʻai o ka lithium iron phosphate ion battery me ka ʻole o nā mea metala hanohano he 0.58-0 wale nō.

6 yuan / WH. Eia kekahi, ʻo ke ola pōʻaiapuni o ka pā uila lithium ion ʻekolu e like me ka pā lithium iron-ion, a ʻo ka nui o ka uku a me ka hoʻokuʻu ʻana o ka pā phosphate ion he 2,000 mau manawa. I ka hoʻohana maʻamau i nā makahiki 4, e hoʻemi ka hapa nui o ka hana pākaukau, e alakaʻi ana i kahi kumukūʻai kiʻekiʻe.

Ma ka palekana o ka pākaukau, ua haʻahaʻa ka wikiwiki o ka wela o ka ʻekolu-dimensional ion cell cell cell, a ua hiki i kahi ākea o 200 degere, a e palekana kēia thermal out of control. ʻO ka lalo ka lalo. Me ka nui o ka ikehu o ka pahu lithium-ion ternary, pōkole ka pōʻino palekana.

ʻOiaʻiʻo, hiki iā mākou ke ʻike pinepine i nā kaʻa uila maʻemaʻe i ka nūhou. No laila, he maʻi nui hoʻi ka palekana o ka pākaukau i nā ʻano kaʻa uila. No ke aha ʻoe e hoʻohana ai i kahi pākaukau lithium-ion ʻekolu-dimensional? Hoʻopili ka mua i nā pono a me nā pōʻino o ka lithium iron phosphate ion battery a me ka ʻekolu-dimensional ion battery.

Nīnau paha kekahi poʻe. Ma muli o ka maikaʻi o ka palekana o ka pahu lithium iron phosphate ion, ua lōʻihi ke ola pōʻaiapuni o ka pākaukau, a ʻoi aku ka haʻahaʻa o ke kumukūʻai, no ke aha e koi mau ai nā mea hana i kā lākou komo ʻana i nā kaʻa uila maʻemaʻe e lawe i kahi pākahi lithium-ion ternary? ʻOiaʻiʻo, ʻo ka lithium iron phosphate ion pākahiko i hoʻolako ʻia ma ka pae komo kaʻa uila maʻemaʻe he manaʻo maikaʻi loa ia. Eia naʻe, he haʻahaʻa ka nui o ka ikehu o kēia manawa o ka lithium iron phosphate ion battery, a ʻo ka NEDC mau mile mile o nā kumu hoʻohālike o kēia ʻano pākaukau ma kahi o 200km, a ʻaʻohe kālā kālā.

Inā hiki ke kiʻi ʻia ka pahu pahu, e hoʻohui ʻia ka helu o nā pahu pākahi, kahi e alakaʻi ai i ka ulu hou o ke kaʻa. A ʻaʻole nui ka nui o ke kumu hoʻohālike maʻamau, no laila ʻaʻole hiki ke waiho ʻia ka nui o nā ʻeke pākahi. No laila, koho ʻia ka pā uila phosphate i kēia manawa e ke kaʻa uila, kāleka kukui uila a me nā ala ʻē aʻe o ka lawe ʻana, a ʻoi aku ka nui o ko lākou wahi no ka pākaukau, a no ke ala paʻa, ʻaʻole pono lākou e noʻonoʻo i ke ola pākaukau.

Ma ke ʻano o ka palekana i ka pākaukau, ʻaʻole hopohopo nui ka poʻe. I kēia manawa, ua hiki ke kiʻekiʻe kiʻekiʻe o ka ʻōnaehana lithium-ion ʻekolu-dimensional a me nā ʻāpana kiʻekiʻe i ke kiʻekiʻe kiʻekiʻe o IP67 wai ʻole a me nā makaʻāinana lepo lepo, ʻoiai i loko o ka wai hohonu 1 mika i hoʻomoʻi ʻia no 30 mau minuke me ka pōʻino ʻole. Eia kekahi, i ka wā pōkole o ka pākaukau, ka overload kiʻekiʻe-voltage, a me ka hui ʻana, e hoʻokaʻawale ka ʻōnaehana i ka mana uila kiʻekiʻe, a me ka pilikia o ka hoʻā ʻana iā ia iho.

Eia kekahi, hiki i ka hana hoʻouka kiʻekiʻe o ka pākaukau lithium ion ʻekolu ke kākoʻo i ka hoʻopiʻi ʻana i ka helu nui, hoʻonui hou i ka pono o ka hoʻopiʻi ʻana, a ʻoi aku ka maikaʻi o ka ʻike. Eia kekahi, i mea e hoʻomaikaʻi ai i ka hoʻokūkū, ua hoʻokumu nā hui kaʻa he nui i kahi kulekele mālama mana a kūʻai hou e hōʻemi i ka pilikia o nā kumukūʻai pākaukau.
