Fahimtar Muhimman Abubuwan Baturi: Yadda Caji Ke Aiki

Kafin a fara amfani da fasahar caji ta DC, yana da mahimmanci a fahimci yadda batirin ke caji da kuma fitar da bayanai.

1. Sinadarin Baturi: Ikon Lithium-Ion

Yawancin batura na zamani masu caji, gami da waɗanda ke cikin wayoyin komai da ruwanka, kwamfyutocin tafi-da-gidanka, da na'urorin lantarki na EV, suna amfani da sulithium-ion (Li-ion)kolithium-polymer (LiPo)sunadarai. Waɗannan batura suna aiki ta hanyar motsa ions na lithium tsakaninkatodin mai kyau(yawanci lithium cobalt oxide, lithium iron phosphate, ko makamancin haka) da kumaanode mai kama da na gajarta(yawanci graphite).

2. Cajin AC da DC: Manyan Bambance-bambance

  • Yana amfani da wutar lantarki mai sauyawa daga wuraren bango.
  • Caja ta cikin na'urar tana canza AC zuwa DC a ƙimar da aka ƙayyade (misali, 5W-30W ga wayoyi, har zuwa 7kW ga EVs).
  • Yawanci a hankali amma a hankali ga lafiyar batirin.
• Cajin DC Mai Sauri (Cajin Sauri):
  • Yana isar da wutar lantarki kai tsaye kai tsaye zuwa ga batirin, yana wucewa da na'urar canza wutar lantarki ta ciki.
  • Yana aiki a matakan ƙarfi mafi girma (misali, 50W-120W ga wayoyi, 50kW-350kW ga EVs).
  • Yana rage lokacin caji sosai amma yana haifar da ƙarin zafi da damuwa.
