He aha ka 800V high voltage platform architecture?

ʻO ka loko o kahi kaʻa i hana ʻia i nā ʻāpana he nui, ʻoi aku ma hope o ka electrification. ʻO ke kumu o ka paepae uila e hoʻohālikelike i nā pono mana o nā ʻāpana like ʻole. Pono kekahi mau ʻāpana i ka volta haʻahaʻa, e like me nā mea uila kino, nā mea leʻaleʻa, nā mea hoʻokele, a me nā mea ʻē aʻe (maʻamau 12V volta platform mana lako), a ʻo kekahi e koi i kahi ʻano.uila kiʻekiʻe, e like me nā ʻōnaehana uila, nā ʻōnaehana uila uila kiʻekiʻe, nā ʻōnaehana hoʻouka, a me nā mea ʻē aʻe (400V / 800V), no laila aia kahi paepae uila kiʻekiʻe a me ka paepae uila haʻahaʻa.

A laila e wehewehe i ka pilina ma waena o 800V a me ka uku wikiwiki loa: I kēia manawa, ʻo ke kaʻa kaʻa uila maʻemaʻe e pili ana i ka ʻōnaehana 400V, ʻo ka motika pili, nā mea pono, nā kaula uila kiʻekiʻe ke ʻano like me ka pae uila, inā hoʻonui ʻia ka ʻōnaehana, ʻo ia ka mea. ma lalo o ke koi mana like, hiki ke hoʻemi ʻia ka manawa i ka hapalua, e liʻiliʻi ka nalowale o ka ʻōnaehana holoʻokoʻa, hoʻemi ʻia ka wela, akā ʻoi aku ka māmā, ʻo ka hana kaʻa ke kōkua nui.

ʻO ka ʻoiaʻiʻo, ʻaʻole pili pono ka hoʻopiʻi wikiwiki ʻana i ka 800V, no ka mea ʻoi aku ka kiʻekiʻe o ka uku o ka pākaukau, e ʻae ana i ka hoʻouka ʻana i ka mana nui, ʻaʻohe mea pili me 800V, e like me ka 400V platform o Tesla, akā hiki iā ia ke hoʻokō wikiwiki loa. ka hoʻouka ʻana ma ke ʻano o ke au kiʻekiʻe. Akā ʻo 800V ka mea e hoʻokō ai i ka hoʻopiʻi mana kiʻekiʻe e hāʻawi i kahi kumu maikaʻi, no ka mea, ʻo ia ka mea e hoʻokō ai i ka mana 360kW, pono 800V theory wale nō 450A i kēia manawa, inā ʻo 400V, pono ia 900A i kēia manawa, 900A i nā kūlana ʻenehana o kēia manawa no nā kaʻa kaʻa. aneane hiki ole. No laila, ʻoi aku ka maikaʻi o ka hoʻopili ʻana i ka 800V a me ka super fast charge, i kapa ʻia ʻo 800V super fast charge technology platform.

I kēia manawa, ʻekolu ʻano okiʻekiʻe-voltʻO nā ʻōnaehana ʻōnaehana i manaʻo ʻia e hoʻokō i ka uku wikiwiki wikiwiki, a ʻo ka ʻōnaehana kiʻekiʻe kiʻekiʻe e manaʻo ʻia e lilo i mea nui:

(1) Pūnaehana holoʻokoʻa kiʻekiʻe uila, ʻo ia hoʻi, 800V mana pākahi + 800V motor, mana uila + 800V OBC, DC/DC, PDU+800V ea ea, PTC.

Pōmaikaʻi: ʻO ka nui o ka hoʻololi ʻana o ka ikehu kiʻekiʻe, no ka laʻana, ʻo ka hoʻololi ʻana o ka ikehu o ka ʻōnaehana uila he 90%, ʻo ka hoʻololi ʻana o ka ikehu o DC / DC he 92%, inā he kiʻekiʻe ka ʻōnaehana holoʻokoʻa, ʻaʻole pono e depressurize ma o DC/DC, ʻo 90%×92%=82.8% ka helu hoʻololi ʻana o ka ikehu ʻōnaehana.

Nāwaliwali: ʻAʻole wale nā ​​koi kiʻekiʻe o ka hale kiʻekiʻe ma ka ʻōnaehana pākaukau, ka mana uila, OBC, DC / DC mana pono e hoʻololi ʻia e Si-based IGBT SiC MOSFET, motor, compressor, PTC, etc. pono e hoʻomaikaʻi i ka hana uila. , ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ke kaʻa no ka wā pōkole, akā i ka wā lōʻihi, ma hope o ke oʻo ʻana o ke kaulahao ʻoihana a loaʻa ka hopena paona. Hoʻemi ʻia ka nui o kekahi mau ʻāpana, hoʻomaikaʻi ʻia ka ikaika o ka ikehu, a hāʻule ke kumukūʻai o ke kaʻa.

(2) Mahele o kauila kiʻekiʻe, ʻo ia hoʻi, 800V pākaukau + 400V motor, uila mana + 400V OBC, DC/DC, PDU + 400V air conditioning, PTC.

Pōmaikaʻi: hoʻohana maʻamau i ke ʻano o kēia manawa, hoʻomaikaʻi wale i ka pā uila, liʻiliʻi ke kumukūʻai o ka hoʻololi ʻana o ke kaʻa, a ʻoi aku ka pono o ka wā pōkole.

Nā pōʻino: hoʻohana ʻia ka haʻahaʻa DC/DC ma nā wahi he nui, a nui ka nalowale o ka ikehu.

(3) ʻO ka hoʻolālā haʻahaʻa haʻahaʻa a pau, ʻo ia hoʻi, 400V pākaukau (hoʻopiʻi 800V i ka moʻo, hoʻokuʻu ʻia 400V i ka like) + 400V motor, mana uila + 400V OBC, DC/DC, PDU + 400V air conditioning, PTC.

Pōmaikaʻi: He liʻiliʻi ka hoʻololi ʻana o ke kaʻa, pono e hoʻololi ʻia ka pākaukau BMS.

Nā hemahema: ka hoʻonui ʻia o ka series, ka piʻi ʻana o ke kumukūʻai pākaukau, hoʻohana i ka pā uila mana, ka hoʻomaikaʻi ʻana i ka pono o ka hoʻopiʻi ʻana.
