AC (Alternating Current)

Home Charging ( Standard 120V Outlet)

  • J1772

    (Level 1 and 2)

    This connector is capable of AC Level 1 and AC Level 2 charging only.

  • CHAdeMO

    (DC Fast Charging - Level 3)

    A standard connector for DC fast charging developed in Japan. Many Asian automakers have released vehicles in North America that use CHAdeMO, although recently some have begun to switch to the higher-power CCS. Tesla offers a CHAdeMO adaptor for their cars, making it possible for Tesla vehicles to charge at public DCFC stations with CHAdeMO.

  • CCS

    (DC Fast Charging - Level 3 & 4)

    Combined Charging System (CCS) is an upgraded fast charge version of the J1772 which is used by most US and European automakers. Level 4 charging is made possible by liquid cooling the cable to reduce weight.

  • NACS

    (DC Fast Charging - Level 3 & 4)

    Until recently, Tesla's connector has exclusively been available for only Tesla vehicles only, since the connector was proprietary to Tesla. That is until the announcement of opening the connector to others and renaming the connector to NACS.

    EV Range shall be providing NACS connectors on stations in the near future given the announcement of numerous automakers.
