Kodi 800V high voltage platform zomangamanga ndi chiyani?

M'kati mwa galimoto imakhala ndi zigawo zambiri, makamaka pambuyo pa magetsi.Cholinga cha nsanja yamagetsi ndikufanana ndi zosowa zamagetsi zamagulu osiyanasiyana.Zigawo zina zimafuna mphamvu yocheperako, monga zamagetsi zamthupi, zida zosangalatsa, zowongolera, ndi zina zambiri (nthawi zambiri 12V voltage papulatifomu magetsi), ndipo zina zimafunikiravoteji yapamwamba, monga machitidwe a batri, makina oyendetsa magetsi apamwamba, makina opangira ndalama, ndi zina zotero (400V / 800V), kotero pali nsanja yotsika kwambiri komanso yotsika kwambiri.

Kenako fotokozerani za ubale wapakati pa 800V ndi chiwongolero chothamanga kwambiri: Tsopano galimoto yonyamula magetsi yamagetsi nthawi zambiri imakhala pafupifupi 400V batire, mota yofananira, zowonjezera, chingwe chamagetsi chamagetsi chimakhalanso mulingo womwewo, ngati voteji yawonjezeka, zikutanthauza kuti pansi pa kufunikira kwa mphamvu komweko, zamakono zimatha kuchepetsedwa ndi theka, kuwonongeka kwa dongosolo lonse kumakhala kochepa, kutentha kumachepetsedwa, komanso kuwonjezereka kopepuka, kuyendetsa galimoto kumathandiza kwambiri.

M'malo mwake, kuthamangitsa mwachangu sikukhudzana mwachindunji ndi 800V, makamaka chifukwa kuchuluka kwa batire ndikokwera kwambiri, kulola kuthamangitsa mphamvu yayikulu, yomwe ilibe kanthu kochita ndi 800V, monga nsanja ya Tesla ya 400V, komanso imatha kukwaniritsa mwachangu kwambiri. kulipiritsa mu mawonekedwe a mkulu wamakono.Koma 800V ndi kukwaniritsa mkulu-mphamvu nawuza amapereka maziko abwino, chifukwa chomwecho kukwaniritsa 360kW nawuza mphamvu, 800V chiphunzitso amangofunika 450A panopa, ngati 400V, pakufunika 900A panopa, 900A mu zamakono mikhalidwe luso magalimoto onyamula ndi. pafupifupi zosatheka.Choncho, n'zomveka kulumikiza 800V ndi wapamwamba kusala kudya pamodzi, wotchedwa 800V wapamwamba mofulumira mlandu nsanja luso.

Pakali pano, pali mitundu itatu yahigh-voltageZomangamanga zamakina zomwe zikuyembekezeka kuti zikwaniritse kuthamanga kwamphamvu kwambiri, ndipo makina amagetsi okwera kwambiri akuyembekezeka kukhala odziwika bwino:

(1) Full system high voltage, ndiko kuti, 800V mphamvu ya batire + 800V mota, mphamvu yamagetsi +800V OBC, DC/DC, PDU + 800V air conditioning, PTC.

Ubwino: Kutembenuka kwamphamvu kwamphamvu, mwachitsanzo, kutembenuka kwamphamvu kwamagetsi oyendetsa magetsi ndi 90%, kutembenuka kwamphamvu kwa DC / DC ndi 92%, ngati dongosolo lonse lili ndi voteji yayikulu, sikofunikira kuti muchepetse nkhawa. DC / DC, mphamvu yosinthira mphamvu ndi 90% × 92% = 82.8%.

Zofooka: Zomanga sizimangofunika kwambiri pa batri, kuwongolera magetsi, OBC, DC/DC zida zamagetsi ziyenera kusinthidwa ndi Si-based IGBT SiC MOSFET, mota, kompresa, PTC, ndi zina zotere ziyenera kuwongolera magwiridwe antchito amagetsi. , Kuwonjezeka kwa mtengo wamagalimoto kwakanthawi kochepa kumakhala kokulirapo, koma m'kupita kwanthawi, pambuyo pa unyolo wamafakitale okhwima ndipo zotsatira zake zimakhala.Kuchuluka kwa magawo ena kumachepetsedwa, mphamvu zamagetsi zimakhala bwino, ndipo mtengo wagalimoto udzatsika.

(2) Gawo lavoteji yapamwamba, ndiko kuti, batire ya 800V + 400V mota, mphamvu yamagetsi +400V OBC, DC/DC, PDU +400V air conditioning, PTC.

Ubwino: makamaka gwiritsani ntchito mawonekedwe omwe alipo, ingokwezani batire yamagetsi, mtengo wakusintha kwagalimoto yamagalimoto ndi yaying'ono, ndipo pali zambiri zothandiza pakanthawi kochepa.

Zoipa: Kutsika kwa DC/DC kumagwiritsidwa ntchito m'malo ambiri, ndipo kutayika kwa mphamvu kumakhala kwakukulu.

(3) Zomangamanga zonse zotsika kwambiri, ndiye kuti, batire ya 400V (kulipira 800V mndandanda, kutulutsa 400V molumikizana) + 400V mota, kuwongolera magetsi + 400V OBC, DC/DC, PDU + 400V air conditioning, PTC.

Ubwino: Kusintha komaliza kwagalimoto kumakhala kochepa, batire imangofunika kusinthidwa BMS.

Zoyipa: kuchuluka kwa mndandanda, kuchuluka kwa mtengo wa batri, kugwiritsa ntchito batire yamphamvu yoyambira, kuwongolera kwachabwino kumakhala kochepa.
