Easee chargers are able to switch between 1-phase and 3-phase charging. This ability depends mainly on these factors:
- The design of your car's charging system
- The capabilities of your car's charging system
There are many models of cars that allow switching back and forth between 1- and 3-phase charging, but most of these allow only to change from 3-phase to 1-phase during a charging session.
It is also possible that there could be some issues with your local power grid at the moment.
The best solution to change a charging session from 1-phase back to 3-phase is to unplug the charging cable from the car and plug it back in. If this continues, contact your vehicle's certified service center to see if there may be a known fix for this issue of switching from 1- to 3-phase. They can also help with guidance on maximizing the charging capabilities of your specific vehicle.
