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 kaʻa uila maʻemaʻe e pili ana i ka ʻōnaehana pākaukau 400V, ʻo ka motika pili, nā mea pono, nā kaula uila kiʻekiʻe ke ʻano like o ka volta, 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 kā Tesla's 400V platform, 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 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 āpau, 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.
