Kodi nsanja ya 800V idzabweretsa zosintha zotani?

Ngati mapangidwe agalimoto yamagetsi akwezedwa kukhala 800V, miyezo ya zida zake zokwera kwambiri idzakwezedwa moyenerera, ndipo inverter idzasinthidwanso kuchokera ku zida zachikhalidwe za IGBT kupita ku zida za SiC za MOSFET. Mtengo wa inverter wokha ndi wachiwiri kwa zigawo za batri. Ngati mukwezera ku SiC, mtengowo udzakwera mpaka mulingo wina.

Koma kwa OEMs, kugwiritsa ntchito silicon carbide sikungoganizira mtengo wa zida zamagetsi, koma chofunikira kwambiri, kusintha kwa mtengo wagalimoto yonse. Chifukwa chake, ndikofunikira kupeza chiyerekezo pakati pa kupulumutsa mtengo komwe kumabwera ndi SiC ndi mtengo wake wokwera.
Ponena za SiC, munthu woyamba kuyesa anali Tesla.

Mu 2018, Tesla anasintha ma modules a IGBT ndi ma silicon carbide modules kwa nthawi yoyamba mu Model 3. Pa mlingo womwewo wa mphamvu, phukusi la silicon carbide modules ndi lochepa kwambiri kuposa la silicon modules, ndipo kutayika kwa kusintha kumachepetsedwa ndi 75%. Komanso, ngati atatembenuzidwa, kugwiritsa ntchito ma module a SiC m'malo mwa ma module a IGBT kumatha kuwonjezera magwiridwe antchito pafupifupi 5%.

Potengera mtengo wake, mtengo wolowa m'malo udakwera pafupifupi yuan 1,500. Komabe, chifukwa cha kuwongolera bwino kwagalimoto, mphamvu ya batire yomwe idayikidwa idachepetsedwa, kupulumutsa ndalama kumbali ya batri.
Izi zitha kuwonedwa ngati njuga yayikulu kwa Tesla. Kuchuluka kwake kwa msika kumachotsa mtengo wake. Tesla adadaliranso kubetcha kwakukulu uku kuti agwire ukadaulo ndi msika wamakina a batri a 400V.
Pankhani ya 800V, Porsche idatsogola pakukonzekeretsa galimoto yamagetsi ya Taycan yamagetsi yonse ndi makina a 800V mu 2019, ndikuyambitsa mpikisano wa zida zamagalimoto amagetsi a 800V.
Pali china chake "chosayenera" pakuwunika ndalama kuchokera ku Porsche. Kupatula apo, imayang'ana kwambiri zamagalimoto apamwamba ndipo imayang'ana pamtengo wapamwamba wamtundu.
Koma ponena za chitukuko cha teknoloji ndi ntchito, iyi ndi ntchito yaikulu yomwe imakhudza thupi lonse. Mwachitsanzo, pansi pa 800V high-voltage charger, voliyumu ya paketi ya batri iyenera kuchulukitsidwa mpaka 800V, apo ayi idzawotchedwa chifukwa champhamvu yayikulu. Kuonjezera apo, sikuti kumangotengera makina opangira ndalama, komanso makina a batri, magetsi oyendetsa magetsi, zowonjezera zowonjezera zowonjezera ndi makina opangira ma wiring, zomwe zimakhudza kuyambira, kuyendetsa galimoto, kugwiritsa ntchito mpweya wa galimoto, ndi zina zotero.

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