No ke aha ke kumuhana wela o BYD blade
ʻO ka "blade battery" o BYD, i hoʻopaʻapaʻa nui ʻia i ka ʻoihana no ka manawa lōʻihi, ua hōʻike hope i kona ʻano maoli.
I kēia mau lā, nui ka poʻe i lohe i ka huaʻōlelo "blade battery", akā ʻaʻole maopopo loa iā ia, no laila i kēia lā e wehewehe mākou i ka "blade battery" i nā kikoʻī.
ʻO wai ka mea nāna i hāʻawi mua i ka pā uila
BYD Lunahoomalu Wang Chuanfu hai mai la BYD "blade pākaukau" (he hou hanauna o ka lithium hao phosphate pihi) e hoʻomaka lehulehu hana ma Chongqing hale hana i loko o Malaki i keia makahiki, a ma Iune i helu 'ia ma ka Han EV Ka manawa mua e lawe. A laila ua paʻi hou ʻo BYD i nā poʻomanaʻo o ka automotive a me nā ʻāpana kālā o nā paepae nūhou nui.
No ke aha ʻo Blade Battery
Hoʻokuʻu ʻia ka pā uila e BYD ma Malaki 29, 2020. ʻO kona inoa piha ʻo ia ka blade type lithium iron phosphate battery, ʻike ʻia hoʻi ʻo "super lithium iron phosphate battery". Hoʻohana ka pākaukau i ka ʻenehana lithium iron phosphate, e hoʻolako mua ʻia me ka BYD "Han" model.
ʻO kaʻoiaʻiʻo,ʻo ka "blade battery" he hanauna hou o ka lithium iron phosphate battery i hoʻokuʻu kokeʻia e BYD,ʻoiaʻiʻo, ua hoʻokumuʻo BYD i ka hoʻomohalaʻana i ka "super lithium iron phosphate" ma o nā makahiki he nui o ka noiʻi , manaʻo paha ka mea hana. ma o ka inoa ʻoi a me ka hoʻohālikelike, e loaʻa ai ka nānā a me ka mana.
Kiʻikuhi hoʻonohonoho ʻana o ka pā uila
Ke hoʻohālikelike ʻia me ka pākaukau lithium iron phosphate mua o BYD, ua hana ʻia ke kī o ka "blade battery" me ka ʻole o ka module, i hoʻopili pololei ʻia i loko o ka pā uila (ʻo ia hoʻi ka ʻenehana CTP), a laila e hoʻomaikaʻi nui ai i 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 pākaukau mana nui loa o ka honua, ua hoʻohana ʻo Ningde Times i ka ʻenehana CPT ma mua o BYD. i Kepakemapa 2019, hōʻike ʻo Ningde Times i kēia ʻenehana i ka Frankfurt Motor Show.
Tesla, Ningde Times, BYD a me Hive Energy, ua hoʻomaka e hoʻomohala a hoʻolaha e hoʻohua nui lākou i nā huahana pili i ka CTP, a ke lilo nei nā ʻeke pākahi mana module-emi i ke ala ʻenehana nui.
ʻO ka pūʻolo pākahi lithium ternary kuʻuna
ʻO ka mea i kapa ʻia ʻo module, he ʻāpana o nā ʻāpana kūpono e lilo i module, hiki ke hoʻomaopopo ʻia he manaʻo o ka hui ʻāpana. Ma kēia kahua o ka pūʻolo pila, ua hoʻohui pū ʻia kekahi mau cell, nā lālani conductive, nā ʻāpana sampling a me kekahi mau mea kākoʻo kūkulu pono e hana i kahi module, i kapa ʻia hoʻi he module.
Ningde Times CPT pūʻolo pila
ʻO ka CPT (cell to pack) ʻo ia ka hoʻohui pololei ʻana o nā cell i loko o kahi pā pākaukau. Ma muli o ka hoʻopau ʻia ʻana o ka loulou hui pū ʻana o ka pākaukau, ua hoʻemi ʻia ka helu o nā ʻāpana pākaukau e 40%, ua hoʻonui ʻia ka nui o ka hoʻohana ʻana o ka pā uila CTP e 15% -20%, a ua hoʻonui ʻia ka hana hana e 50%, ʻo ia ka mea e hōʻemi nui ai i ke kumukūʻai hana o ka pā uila.
Pehea e pili ana i ke kumu kūʻai o ka pā uila
Ma ke kamaʻilio ʻana i ke kumukūʻai, ʻaʻole hoʻohana ʻo lithium iron phosphate i nā metala liʻiliʻi e like me ka cobalt, ʻo ke kumukūʻai kona pono. Ua hoʻomaopopo ʻia ʻo 2019 ternary lithium battery cell market e hāʻawi ʻia ma kahi o 900 RMB / kW-h, ʻoiai ka hāʻawi ʻana o ka lithium iron phosphate cell cell ma kahi o 700 RMB / kW-h, ma ka wā e hiki mai ana e helu ʻia ʻo Han no ka laʻana, kāna. hiki i ka laulā ke hiki i 605km, ua wānana ʻia ʻoi aku ka nui o ka pā uila ma mua o 80kW-h, ʻo ka hoʻohana ʻana i nā pākahi lithium hao phosphate hiki ke emi ma kahi o 16,000 RMB(2355.3 USD) ʻoi aku ka liʻiliʻi. E noʻonoʻo ʻoe i kahi kaʻa ikehu hou ʻē aʻe me ke kumu kūʻai like a me ke ʻano like me BYD Han, ʻo ka pā pākaukau wale nō ka loaʻa ʻana o ke kumukūʻai o 20,000 RMB(2944.16 USD), no laila maopopo ka mea ikaika a nāwaliwali paha.
I ka wā e hiki mai ana, ʻelua mau mana o BYD Han EV: ka mana hoʻokahi-motor me ka mana 163kW, 330N-m peak torque a me 605km NEDC range; ʻO ka mana ʻelua-motor me ka mana 200kW, 350N-m kiʻekiʻe torque a me 550km NEDC.
Ma ka lā 12 o ʻAukake, ua hōʻike ʻia, ua hāʻawi ʻia ka pā uila o BYD i Tesla's Gigafactory Berlin, i manaʻo ʻia e hoʻolako ʻia me nā kaʻa Tesla ma waho o ka laina ma ka hopena o ʻAukake a i ka hoʻomaka ʻana o Sepatemaba ma ka mua, ʻoiai ʻo Tesla's Shanghai gigafactory. ʻaʻohe manaʻo e hoʻohana i nā pā BYD.
Ua hōʻoia ʻo teslamag.de i ka ʻoiaʻiʻo o ka nūhou. Ua hōʻike ʻia ka Model Y me nā pihi BYD i ʻae ʻia 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 he 55 kWh ka nui o ka pākaukau a me ka laulā o 440 km.
He aha nā mea maikaʻi o nā ʻauamo blade
Palekana:I kēia mau makahiki i hala iho nei, ua pinepine nā pōʻino palekana kaʻa uila, a ʻo ka hapa nui o ia mau mea ma muli o ke ahi pākaukau. Hiki ke ʻōlelo ʻia ʻo "blade battery" ka palekana maikaʻi loa ma ka mākeke. Wahi a BYD i paʻi ʻia nā hoʻokolohua e pili ana i ka hoʻāʻo ʻana i ka nail nail penetration test, hiki iā mākou ke ʻike i ka "blade battery" ma hope o ke komo ʻana, hiki ke mālama ʻia ka mahana pākaukau ma waena o 30-60 ℃, ʻo ia ke kumu o ka lōʻihi o ke kaʻapuni ʻana o ka puʻupuʻu, kahi ākea ākea a me ka wela wikiwiki. ka hoopau ana. Ua kuhikuhi ʻo Ouyang Minggao, he mea hoʻonaʻauao o ka Chinese Academy of Science, ʻo ka hoʻolālā ʻana o ka pā uila e hoʻoemi i ka wela a hoʻopau wikiwiki i ka wela i ka wā pōkole, a loiloi i kāna hana ma ka "nail penetration test" he maikaʻi loa.
Kiʻekiʻe ikehu kiʻekiʻe:Ke hoʻohālikelike ʻia i nā ʻāpana lithium ternary, ʻoi aku ka palekana o nā pā lithium iron phosphate a ʻoi aku ka lōʻihi o ke ola pōʻai, akā ma mua i ka nui o ka ikehu pākaukau ua paʻi ʻia ke poʻo. I kēia manawa, ʻoi aku ka nui o ka puʻupuʻu wh / kg ma mua o ka hanauna mua o nā pā, ʻoiai ke piʻi nei ka 9% i ka nui o ka ikehu wh / l, akā ʻo ka piʻi ʻana a hiki i 50%. ʻO ia hoʻi, hiki ke hoʻonui ʻia ka mana pākaukau "blade" e 50%.
Ka lōʻihi o ke ola pila:Wahi a nā hoʻokolohua, ʻoi aku ka lōʻihi o ke ola ʻana o ka pā uila ma mua o 4500 mau manawa, ʻo ia hoʻi, ʻoi aku ka liʻiliʻi o ka pohō ʻana o ka pākaukau ma mua o 20% ma hope o 4500 mau manawa i hoʻopaʻa ʻia, ʻoi aku ke ola ma mua o 3 mau manawa o ka pākahi lithium ternary, a hiki i ke ola mileage like o ka pā uila. ma mua o 1.2 miliona km.
Pehea e hana ai i kahi hana maikaʻi ma luna o ka ʻili o ka pūpū kumu, ka pā anuanu, ka uhi o luna a me lalo, ka pā, ka baffle a me nā mea ʻē aʻe e hoʻokō ai i nā koi palekana o ka insulation, insulation wela, flame retardant, fireproof a hoʻokō i nā koi o ka hana automated. ? ʻO ia ka paʻakikī nui a me ke kuleana o ka hale hana uhi i ka wā hou.
