The SDEV smartphone application lets users locate electric vehicle charging stations through a searchable map with GPS capability and pay for charging on those stations with an SDG&E account. The map enables users to view the status and availability of SDG&E managed chargers near their current location. Once a charging station is selected, driving directions are offered. Also, stations can be saved to the user’s favorites, allowing quick and easy access to the stations they use the most. Additional features include viewing charging session and billing history, managing payment cards, and editing their profile for SDG&E members.
