Maxay yihiin faa'iidooyinka 800V ee cadaadiska sarreeya ee qof kastaa uu ku kulul yahay, oo ma matali kartaa mustaqbalka taraamka?

Welwelka kala duwani waa cidhiidhiga ugu weyn ee xaddidaya barwaaqada suuqa baabuurta korontada, iyo macnaha ka dambeeya falanqaynta taxaddarka leh ee walaaca kala duwani waa "dulqaad gaaban" iyo "lacag gaabis ah". Waqtigan xaadirka ah, marka lagu daro nolosha batteriga, way adagtahay in la sameeyo horumar la taaban karo, sidaas darteed "lacag degdeg ah" iyo "supercharge" ayaa ah diiradda qaabka hadda ee shirkadaha baabuurta kala duwan. Markaa800V danab saremadal ayaa timid.

Macaamiisha caadiga ah, 800V madal koronto-sare ah oo ay xayeysiiyaan shirkadaha baabuurtu waa erey farsamo oo keliya, laakiin sida tignoolajiyada muhiimka ah mustaqbalka, waxay sidoo kale la xiriirtaa khibradda baabuurka macaamiisha, waana inaan faham guud ka yeelannaa tignoolajiyadan cusub. . Sidaa darteed, warqadani waxay sameyn doontaa falanqayn qoto dheer oo ku saabsan 800V ee cadaadiska sarreeya ee dhinacyada kala duwan sida mabda'a, baahida, horumarinta iyo soo degista.

Maxaad ugu baahan tahay madal 800V ah?

Labadii sano ee la soo dhaafay, iyada oo ay si tartiib tartiib ah u kordheen tirada baabuurta korontada, tirada xajmigu waxa ay kor u kacday isku mar, laakiin saamiga tuulanku isma dhimin. Dhammaadka 2020, "Samiga-baabuurka" ee baabuurta tamarta cusub ee gudaha waa 2.9: 1 (tirada baabuurtu waa 4.92 milyan iyo tirada xajmigu waa 1.681 milyan). Sannadka 2021, saamiga baabuurka lagu ururinayo wuxuu noqonayaa 3:1, kaas oo aan hoos u dhacayn balse uu kordhi doono. Natiijadu waxay tahay in wakhtiga safku ka dheer yahay wakhtiga dallacaadda.

Ka dib marka la eego tirada tirada xirmooyinka dallacadu ma sii wadi karaan, si loo yareeyo wakhtiga shaqada ee ku dallacaadaha, tignoolajiyada degdega ah ee dallacadu waa lagama maarmaan.

Korodhka xawaaraha dallacaadda waxa si fudud loo fahmi karaa kororka awoodda dallacaadda, taas oo ah, P = U ·I ee P Sidaa darteed, haddii aad rabto inaad kordhiso awoodda dallacaadda, hayso mid ka mid ah tamarta ama hadda aan isbeddelin, kordhinta tamarta ama hadda waxay hagaajin kartaa awoodda dallacaadda. Soo bandhigida madal danab sare leh ayaa ah in la wanaajiyo hufnaanta dallacaadda dhamaadka baabuurka lana xaqiijiyo dib u dallacaadda degdega ah ee dhamaadka gaadhiga.

Qalabka 800Vbaabuurta korantada waa doorashada guud ee dallaca degdega ah. Batariyada korontada, ku dallaca degdega ah ayaa asal ahaan ah in la kordhiyo dallacaadda hadda ee unugga, oo sidoo kale loo yaqaano saamiga dallaca; Waqtigan xaadirka ah, shirkado badan oo baabuurta ayaa ku jira qaabeynta 1000 kiiloomitir oo kala duwan oo wadis ah, laakiin tiknoolajiyada hadda jira, xitaa haddii loo horumariyo baytariyada adag, waxay sidoo kale u baahan tahay baakidh koronto ah oo ka badan 100kWh, taas oo horseedi doonta kororka tirada unugyada, haddii goobta caadiga ah ee 400V ay sii socoto isticmaalka, tirada unugyada isbarbar-dhigga ayaa kordha, taasoo keentay kororka baska hadda. Waxay caqabad weyn ku keenaysaa qeexida siliga naxaasta iyo tuubada kulaylka.

Sidaa darteed, waa lagama maarmaan in la beddelo qaab dhismeedka isbarbardhigga taxanaha ah ee unugyada batteriga ee xirmada batteriga, la yareeyo isbarbardhigga oo la kordhiyo taxanaha, si loo kordhiyo dallacaadda hadda iyadoo la ilaalinayo goobta hadda jirta ee heer macquul ah. Si kastaba ha noqotee, marka tirada taxanaha ahi korodho, batteriga dhamaadka batteriga waa la kordhin doonaa. Korontada looga baahan yahay batteriga 100kWh si loo gaaro 4C degdeg ah waxay ku saabsan tahay 800V. Si loo waafajiyo shaqada degdegga ah ee dallacaadda ee dhammaan heerarka moodooyinka, 800V qaab dhismeedka korantada ayaa ah doorashada ugu fiican.
