Kodi mamangidwe a 800V apamwamba 800V apamwamba ndi ati?

Mkati mwagalimoto umapangidwa ndi zinthu zambiri, makamaka pambuyo pakusanthula. Cholinga cha nsanja yamagetsi ikugwirizana ndi zofunikira za magawo osiyanasiyana. Zigawo zina zimafuna mphamvu yotsika, monga makompyuta amagetsi, zida zosangalatsa, olamulira, etc. (Nthawi zambiri anthu a 15V amafunikiramagetsi kwambiri, monga makina a batri, magetsi oyendetsa magetsi apamwamba, magwiridwe antchito, ndi zina.

Ndiye fotokozerani ubale pakati pa 800V ndi galimoto yayikulu pagalimoto nthawi yayitali Pansi pa mphamvu yomweyo, zomwe zitha kuchepetsedwa ndi theka, kutayika konse kwamachitidwe kumakhala kocheperako, kutentha kumachepetsedwa, komanso zopepuka, magwiridwe ake agalimoto ndi othandizira kwambiri.

M'malo mwake, kuyimitsa mwachangu sikugwirizana mwachindunji ndi 800V, makamaka chifukwa cholipiritsa chambiri, chopereka ndalama zambiri, zomwe sizimagwirizana ndi 800V, ngati nsanja ya Tesla, koma imathanso kuchita mwachangu kwambiri Kulipiritsa mwa mawonekedwe apamwamba. Koma 800v ndikukwaniritsa ntchito yayikulu kwambiri imapereka maziko abwino, chifukwa zomwezo kuti akwaniritse mphamvu 360kW, chiphunzitso cha 800a chimangofunika ma 400a, 900a pazomwe zimachitika pafupifupi zosatheka. Chifukwa chake, ndizomveka kulumikiza 800v ndi Super mermer limodzi, otchedwa 800v Super Flate Watchform Platifomu.

Pakadali pano, pali mitundu itatu yamagetsi kwambiriOpanga dongosolo omwe akuyembekezeredwa kuti akwaniritse bwino kwambiri, ndipo magetsi amayembekezeredwa kwambiri kuti akhale chachikulu:

.

Ubwino: mwachitsanzo, mphamvu zotembenuka mphamvu zamagetsi zamagetsi zamagetsi ndi 90%, kutembenuka kwamphamvu kwa DC / DC ndi 52%, ngati dongosolo lonse likhala lonyansa DC / DC, makina osinthira mphamvu zamagetsi ndi 90% × 92% = 82.8%.

Zofooka: Sikuti amangofuna kungoyambira pa Batri, Kuwongolera Magetsi, Obc, DC , Kukula kwakanthawi kochepa kukwera kumakhala kwakukulu, koma munthawi yayitali, pambuyo pa utoto wa mafakitale ndi wokhwima komanso woponderezedwa. Kuchuluka kwa ziwalo zina kumachepetsedwa, mphamvu zamagetsi zimayenda bwino, ndipo mtengo wagalimoto udzagwa.

(2) Gawo lamagetsi kwambiri, ndiye kuti, 800V Battery + 400V Motor, magetsi + 400v obc, DC / DC, PDH

Ubwino: Kugwiritsanso ntchito kapangidwe kake komwe kulipo, kokha kungokweza batiri lamagetsi, mtengo wa kusintha kwa galimoto ndikochepa, ndipo pali phindu lalikulu m'nthawi yochepa.

Zovuta: DC / DC SIRD-pansi imagwiritsidwa ntchito m'malo ambiri, ndipo kutayika kwamphamvu ndikofunikira.

.

Ubwino: Kusintha kwagalimoto ndikochepa, batiri limangofunika kusinthidwa BMS.

Zovuta: Kuchulukitsa kwa mitengo ya batri, gwiritsani ntchito batire yoyambirira, kusintha kwa ndalama ndizochepa.
