Chifukwa chiyani magalimoto amagetsi amafunikira 800V?

Opanga magalimoto ndi eni ake onse amalota za zotsatira za "kuchaja kwa mphindi 5 ndikuyendetsa 200km".

Kuti izi zitheke, zosowa ziwiri zazikulu ndi mfundo zopweteka ziyenera kuthetsedwa:
Choyamba, ndikuwongolera kwambiri momwe batire imagwirira ntchito komanso kuonjezera liwiro la batri mwachangu.
Chachiwiri, ndikuwongolera magwiridwe antchito a galimoto yonse ndikukulitsa kutalika kwa galimotoyo pansi pa mphamvu yomweyo.
Apa, tingagwiritse ntchito fizikisi ya sukulu ya sekondale kuti timvetse mwachidule: P=UI. Chifukwa chake ngati mukufuna kuwonjezera mphamvu, pali njira ziwiri zokha zowonjezerera mphamvu yamagetsi kapena kuonjezera mphamvu yamagetsi.
Komabe, mafunde akuluakulu angayambitse kutayika kwakukulu kwa kutentha m'mifuti zochapira, zingwe ndi zigawo zazikulu za mabatire amagetsi, ndipo malire apamwamba a kusintha kwa malingaliro si akulu. Chifukwa chake, njira yopitira ku mphamvu yowonjezera ndi "yosatheka", ayi, iyenera kukhala "yosatali kwambiri".
Nanga bwanji za kuwonjezera mphamvu yamagetsi?
Pamene mphamvu ya dongosolo ikukhalabe yokhazikika, mphamvu yochaja idzawirikiza kawiri monga mphamvu ya dongosolo, ndiko kuti, liwiro la kuchaja lidzawirikiza kawiri, ndipo nthawi yochaja idzafupikitsidwa kwambiri. Kuphatikiza apo, pansi pa mphamvu yomweyo yochaja, ngati mphamvu yamagetsi ili yokwera, mphamvu yamagetsi imatha kuchepetsedwa, ndipo waya sayenera kukhala wokhuthala kwambiri, ndipo mphamvu ya kutentha ya waya imachepanso.

Chifukwa chake, ngati mukugwiritsabe ntchito kukula kwa chingwe choyambirira cha 400V, mutha kuwonjezera mphamvu yochaja. Izi zikutanthauza kuti pansi pa nsanja ya 800V, zingwe zopyapyala zochaja zingagwiritsidwe ntchito.
Kafukufuku wa Huawei akuwonetsa kuti kuyitanitsa mwachangu pogwiritsa ntchito njira ya 800V high-voltage kumathandizira kuyitanitsa mphamvu yayikulu ya 30%-80% SOC, pomwe njira yamagetsi otsika kwambiri imatha kungoyitanitsa mphamvu yayikulu pa 10%-20% SOC, ndipo mphamvu yoyitanitsa imatsika kwambiri m'malo ena mwachangu. Zikuoneka kuti njira yamagetsi yapamwamba ya 800V imatha kuthandizira kuyitanitsa mwachangu kwa nthawi yayitali.
Kugwira ntchito bwino kwa galimoto yonse, zomwe zikutanthauza kuti ngati mphamvu yamagetsi ikuyenda bwino, mphamvu ya batri imakhala yokwera, mphamvu ya injini imakhala yokulirapo, komanso mphamvu ya injiniyo imakhala yokwera.
Chifukwa chake, nsanja yamagetsi ya 800V imatha kupeza mphamvu zambiri komanso torque yabwino, komanso magwiridwe antchito abwino othamangitsa. Ngakhale kuti kusintha kwa mphamvu zomwe zimabweretsedwa ndi 800V kumagalimoto amagetsi ndi kwabwino, chimodzi mwa zopinga zazikulu pakukhazikitsa 800V ndi vuto la mtengo.

Ngati mukufuna kudziwa zambiri za izi, chonde musazengereze kulankhulana nafe.
