Chifukwa chiyani magalimoto amagetsi amafunikira 800V?

Onse opanga ndi eni magalimoto amalota za zotsatira za "kulipiritsa kwa mphindi 5 ndikuyendetsa 200km".

Kuti izi zitheke, zofunika ziwiri zazikulu ndi mfundo zowawa ziyenera kuthetsedwa:
Chimodzi, ndikuwongolera kwambiri magwiridwe antchito ndikuwonjezera kuthamanga kwa batire.
Chachiwiri, ndikuwongolera kuyendetsa bwino kwagalimoto yonse ndikukulitsa kuchuluka kwa magalimoto pansi pamagetsi omwewo.
Apa, titha kugwiritsa ntchito sayansi yasukulu yasekondale kuti timvetsetse mwachidule: P=UI. Chifukwa chake ngati mukufuna kuwonjezera mphamvu, pali njira ziwiri zokha zowonjezerera pakali pano kapena kuwonjezera magetsi.
Komabe, mafunde akuluakulu adzawononga kutentha kwakukulu pakulipiritsa mfuti, zingwe ndi zigawo zikuluzikulu za mabatire amphamvu, ndipo malire apamwamba akusintha kwamalingaliro siakulu. Chifukwa chake, njira yopititsira patsogolo pakali pano ndi "yosafikirika", ayi, iyenera kukhala "osati kutali kwambiri".
Nanga bwanji kuwonjezera mphamvu yamagetsi?
Pamene dongosolo lamakono limakhalabe losasintha, mphamvu yowonjezera idzawirikiza kawiri monga mphamvu yamagetsi, ndiye kuti, kuthamanga kwapamwamba kumawirikiza kawiri, ndipo nthawi yolipira idzafupikitsidwa kwambiri. Kuonjezera apo, pansi pa mphamvu yolipiritsa yomweyi, ngati voteji ndi yapamwamba, yamakono ikhoza kuchepetsedwa, ndipo waya sayenera kukhala wandiweyani, ndipo kukana kutentha kwamphamvu kwa waya kumachepetsedwa.

Chifukwa chake, ngati mukugwiritsabe ntchito kukula kwa chingwe cha 400V choyambirira, mutha kuwonjezera mphamvu yolipirira. Izi zikutanthauza kuti pansi pa nsanja ya 800V, zingwe zocheperako zitha kugwiritsidwa ntchito.
Kafukufuku wa Huawei akuwonetsa kuti kulipiritsa mwachangu pogwiritsa ntchito 800V high-voltage mode kumathandizira pazipita zamphamvu za 30% -80% SOC, pomwe otsika-voltage apamwamba-panopa amatha kungowonjezera mphamvu pa 10% -20% SOC, ndi mphamvu yopangira. amatsika kwambiri m'magulu ena. kudya. Zitha kuwoneka kuti 800V high-voltage mode imatha kuthandizira kuthamanga kwanthawi yayitali.
Kukwera kwamphamvu kwagalimoto yonseyo, zomwe zikutanthauza kuti pansi pazikhalidwe zanthawi zonse, mphamvu ya batri imakwera, mphamvu yamotoyo imachulukira, komanso kuyendetsa bwino kwagalimoto.
Choncho, 800V high-voltage nsanja mosavuta kupeza mphamvu mkulu ndi makokedwe, komanso bwino mathamangitsidwe ntchito. Ngakhale kupititsa patsogolo mphamvu zowonjezera mphamvu zomwe zimabweretsedwa ndi 800V kumagalimoto amagetsi ndizoyenera, chimodzi mwazolepheretsa kwambiri kukhazikitsidwa kwa 800V ndi nkhani yamtengo wapatali.

Ngati mukufuna kudziwa zambiri za izi, chonde omasuka kulankhula nafe.
