An Bayyana Cajin Saurin DC

Cajin AC shine mafi sauƙin nau'in caji don nemo - kantuna suna ko'ina kuma kusan duk cajar EV da kuke haɗu da su a gidaje, wuraren cin kasuwa, da wuraren aiki sune Cajin Level2. Caja AC yana ba da wuta ga cajar kan allo na abin hawa, yana mai da waccan wutar AC zuwa DC don shigar da baturin. Adadin karɓar cajar kan jirgi ya bambanta da iri amma yana iyakance saboda dalilai na farashi, sarari da nauyi.

Cajin Saurin DC yana ƙetare duk iyakokin caja a kan jirgi da juyawa da ake buƙata, maimakon samar da wutar DC kai tsaye zuwa baturi, saurin caji yana da yuwuwar ƙarawa sosai. Lokutan caji sun dogara da girman baturi da fitarwar na'urar, da sauran dalilai, amma yawancin motoci suna da ikon samun cajin 80% cikin kusan ko ƙasa da sa'a guda ta amfani da mafi yawan caja masu saurin DC a halin yanzu.

 4.Tashar caji na DC

Tashar cajin DC ta fi ƙarfin fasaha da yawa kuma ta fi tsada fiye da tashar cajin AC kuma haka ma tana buƙatar tushe mai ƙarfi.
