No ke aha i lilo ai ka pila BYD i kumuhana wela i kēia manawa
Ua hōʻike hope ʻia ke ʻano maoli o ka "blade battery" a BYD, ka mea i kūkākūkā nui ʻia ma ka ʻoihana no ka manawa lōʻihi.
Malia paha i kēia mau lā aku nei ua lohe ka poʻe he nui i ka huaʻōlelo "blade battery", akā ʻaʻole paha i kamaʻāina loa me ia, no laila i kēia lā e wehewehe mākou i ka "blade battery" me nā kikoʻī.
ʻO wai ka mea nāna i hoʻokumu mua i ka pila blade
Ua hoʻolaha ʻo Wang Chuanfu, Luna Hoʻomalu o BYD, e hoʻomaka ana ka hana nui ʻana o BYD "blade battery" (he hanauna hou o nā pila lithium hao phosphate) ma ka hale hana ʻo Chongqing i Malaki o kēia makahiki, a ma Iune i helu ʻia ma ka Han EV no ka manawa mua e lawe ai. A laila ua paʻi hou ʻo BYD i nā poʻomanaʻo o nā ʻāpana kaʻa a me nā ʻāpana kālā o nā kahua pāpāho nui.
No ke aha i hoʻohana ai i ka pākaukau Blade
Ua hoʻokuʻu ʻia ka pākahiko pahi e BYD ma Malaki 29, 2020. ʻO kona inoa piha ʻo ia ka pākahiko lithium hao phosphate ʻano pahi, i ʻike ʻia hoʻi ʻo "super lithium hao phosphate pākahiko". Hoʻohana ka pākahiko i ka ʻenehana lithium hao phosphate, e hoʻolako mua ʻia me ke kumu hoʻohālike BYD "Han".
ʻO ka mea ʻoiaʻiʻo, ʻo ka "blade battery" kahi hanauna hou o ka lithium iron phosphate battery i hoʻokuʻu hou ʻia e BYD, ʻoiai, ua kālele ʻo BYD i ka hoʻomohala ʻana o ka "super lithium iron phosphate" ma o nā makahiki he nui o ka noiʻi, malia paha ke manaʻolana nei ka mea hana ma o kahi inoa ʻoi a me ke ʻano hoʻohālikelike, e loaʻa ai ka nānā a me ka mana hou aku.
Kiʻikuhi hoʻonohonoho pākahiko pahi
Ke hoʻohālikelike ʻia me ka pākahiko lithium hao phosphate ma mua o BYD, hana ʻia ke kī o ka "pākaukau blade" me ka ʻole o ka module, i hoʻohui pololei ʻia i loko o ka pā pākahiko (ʻo ia hoʻi ka ʻenehana CTP), no laila e hoʻomaikaʻi nui ana i ka pono o ka hoʻohui ʻana.
Akā ʻo ka ʻoiaʻiʻo, ʻaʻole ʻo BYD ka mea hana mua e hoʻohana i ka ʻenehana CPT. Ma ke ʻano he mea hana pila mana nui loa i hoʻokomo ʻia ma ka honua, ua hoʻohana ʻo Ningde Times i ka ʻenehana CPT ma mua o BYD. I Kepakemapa 2019, ua hōʻike ʻo Ningde Times i kēia ʻenehana ma ka Frankfurt Motor Show.
ʻO Tesla, Ningde Times, BYD a me Hive Energy, ua hoʻomaka e hoʻomohala a hoʻolaha e hana nui lākou i nā huahana e pili ana iā CTP, a ke lilo nei nā ʻeke pila mana module-less i ke ala ʻenehana nui.
Pūʻolo pākahiko lithium ternary kuʻuna
ʻO ka mea i kapa ʻia ʻo module, ʻo ia kekahi o nā ʻāpana pili e hana ana i kahi module, hiki ke hoʻomaopopo ʻia he manaʻo o ka ʻākoakoa ʻana o nā ʻāpana. Ma kēia kahua o ka pūʻolo pila, ua hoʻohui pū ʻia kekahi mau cell, nā lālani alakaʻi, nā ʻāpana laʻana a me kekahi mau ʻāpana kākoʻo kūkulu e hana i kahi module, i kapa ʻia hoʻi he module.
Pūʻolo pila Ningde Times CPT
ʻO ka CPT (cell to pack) ka hoʻohui pololei ʻana o nā cell i loko o kahi pākaukau pākahiko. Ma muli o ka hoʻopau ʻia ʻana o ka loulou hui module pākahiko, ua hoʻemi ʻia ka helu o nā ʻāpana pākaukau pākahiko e 40%, ua hoʻonui ʻia ka nui o ka hoʻohana ʻana o ka pākaukau pākahiko CTP e 15%-20%, a ua hoʻonui ʻia ka pono hana e 50%, kahi e hoʻemi nui ai i ke kumukūʻai hana o ka pākaukau mana.
Pehea e pili ana i ke kumukūʻai o ka pākahiko pahi
E kamaʻilio ana no ke kumukūʻai, ʻaʻole hoʻohana ka pākahiko lithium hao phosphate iā ia iho i nā metala kakaikahi e like me ka cobalt, ʻo ke kumukūʻai kona pono. Ua maopopo ʻia ʻo ka mākeke kelepona pākahiko lithium ternary 2019 e hāʻawi ana ma kahi o 900 RMB / kW-h, ʻoiai ʻo ka hāʻawi ʻana o nā kelepona pākahiko lithium hao phosphate ma kahi o 700 RMB / kW-h, i ka wā e hiki mai ana e helu ʻia ʻo Han no ka laʻana, hiki i kona laulā ke hiki i 605km, ua wānana ʻia ka pūʻolo pākahiko e ʻoi aku ma mua o 80kW-h, ʻo ka hoʻohana ʻana i nā pākahiko lithium hao phosphate hiki ke emi ma ka liʻiliʻi he 16,000 RMB (2355.3 USD). E noʻonoʻo i kahi kaʻa ikehu hou kūloko me ke kumukūʻai like a me ka laulā e like me BYD Han, ʻo ka pūʻolo pākahiko wale nō he pono kumukūʻai o 20,000 RMB (2944.16 USD), no laila ua maopopo ka mea ikaika a nāwaliwali paha.
I ka wā e hiki mai ana, loaʻa iā BYD Han EV ʻelua mau mana: ka mana motika hoʻokahi me ka mana 163kW, ka torque kiʻekiʻe 330N-m a me ka pae NEDC 605km; ka mana motika pālua me ka mana 200kW, ka torque kiʻekiʻe loa 350N-m a me ka pae NEDC 550km.
Ma ʻAukake 12, ua hōʻike ʻia ua hāʻawi ʻia ka pākahiko pahi o BYD i ka Gigafactory Berlin o Tesla, kahi i manaʻo ʻia e hoʻolako ʻia me ka pākahiko o nā kaʻa Tesla mai ka laina ma ka hopena o ʻAukake a hiki i ka hoʻomaka o Kepakemapa ma ka mua loa, ʻoiai ʻaʻohe hoʻolālā o ka gigafactory Shanghai o Tesla e hoʻohana i nā pākahiko BYD.
Ua hōʻoia ʻo teslamag.de i ka ʻoiaʻiʻo o ka nūhou. Ua hōʻike ʻia ua loaʻa i ka Model Y me nā pila BYD ka ʻae ʻano mai ka EU, i hāʻawi ʻia e ka Dutch RDW (Dutch Ministry of Transport) ma Iulai 1, 2022. Ma ka palapala, ua kapa ʻia ka Model Y hou ʻo Type 005, me ka mana o ka pila he 55 kWh a me ka mamao o 440 km.
He aha nā pōmaikaʻi o nā pila pahi
Palekana:I nā makahiki i hala iho nei, ua pinepine nā ulia palekana o ke kaʻa uila, a ʻo ka hapa nui o lākou ua hoʻokumu ʻia e nā ahi pila. Hiki ke ʻōlelo ʻia ʻo ka "pākaukau pahi" ka palekana maikaʻi loa ma ka mākeke. Wahi a nā hoʻokolohua i paʻi ʻia e BYD ma ka hoʻāʻo komo kui pila, hiki iā mākou ke ʻike i ka "pākaukau pahi" ma hope o ke komo ʻana, hiki ke mālama ʻia ka mahana o ka pila ma waena o 30-60 ℃, ʻo ia no ka mea he lōʻihi ke kaapuni pila pahi, he ʻili nui a he wikiwiki ka hoʻopuehu wela. Ua kuhikuhi ʻo Ouyang Minggao, he academician o ka Chinese Academy of Sciences, ʻo ka hoʻolālā ʻana o ka pākaukau pahi e hoʻoulu ai i ka wela liʻiliʻi a hoʻopuehu wikiwiki i ka wela i ka wā e pōkole ana, a ua loiloi i kāna hana ma ka "hoʻāʻo komo kui" he maikaʻi loa.
Ka nui o ka ikehu:Ke hoʻohālikelike ʻia me nā pila lithium ternary, ʻoi aku ka palekana o nā pila lithium hao phosphate a he ola pōʻaiapuni lōʻihi ko lākou, akā ma mua, ua paʻi ʻia ke poʻo o ka nui o ka ikehu o ka pila. I kēia manawa, ʻoi aku ka nui o ka nui o ka pila blade wh/kg ma mua o ka hanauna mua o nā pila, ʻoiai ua piʻi ka nui o ka ikehu wh/l he 9%, akā ua piʻi a hiki i ka 50%. ʻO ia hoʻi, hiki ke hoʻonui ʻia ka mana o ka pila "blade battery" e 50%.
Ola lōʻihi o ka pila:Wahi a nā hoʻokolohua, ʻoi aku ka nui o ke ola o ka hoʻouka ʻana o ka pila pahi ma mua o 4500 mau manawa, ʻo ia hoʻi, ʻoi aku ka emi ʻana o ka pila ma mua o 20% ma hope o 4500 mau manawa e hoʻouka ai, ʻoi aku ke ola ma mua o 3 mau manawa o ka pila lithium ternary, a ʻo ke ola mileage like o ka pila pahi hiki ke ʻoi aku ma mua o 1.2 miliona km.
Pehea e hana ai i kahi hana maikaʻi ma ka ʻili o ka pūpū koʻikoʻi, ka papa hoʻoluʻu, ka uhi o luna a me lalo, ka pā, ka baffle a me nā ʻāpana ʻē aʻe e hoʻokō ai i nā koi palekana o ka insulation, ka insulation wela, ka flame retardant, ka fireproof a me nā koi o ka hana automated? ʻO ia ka pilikia nui a me ke kuleana o ka hale hana uhi i ka wā hou.
