Introducing RPX™

EVSession Reduce Power Index™

This new EVSession metric tracks the percentage of fast chargers that are operating at a power level less than advertised. These derated chargers can lead to longer charging sessions, charger hopping, and an overall poor customer experience.

Check back soon for a map on our Dashboard with pins showing the locations of these chargers for better trip planning.

DC Fast Charger Availability

Reliable DC Fast Charging is a must for electric fleets, EV road trips, and for those without a home charging solution. Station maps and in-vehicle navigation show you where the stations are but availability of charging stations is far from accurate.

EVSession tracks DC Fast Charging station availability from all the top operators so you can find a reliable place to charge.

  • EV Drivers can monitor or get alerts on their favorite stations, or plug in their destination for a customized health report of charge points along their route.

  • Fleet Managers can register their routes for daily updates and alerts on DCFC station availability, usage, and reliability.

  • Government agencies can monitor the health of sites funded by their electrification programs.

Station Health

EVSession CHX™— the Charging Health Index — is a score calculated for each station based on its recent data history.


EVSession Usage will show you the busy times for your favorite stations. It includes recent alerts from station unavailability or payment system failures.


Do you have a favorite station or are you planning a trip? EVSession Alerts will update you with any changes you need to know.
