CHARGING SESSION
When the charging station is ready to be used you can simply follow the procedures
described on the Etrel INCH’s LCD screen.
You can choose between two charging modes:
Fast charging (default)
Interactive charging
Charging modes are chosen during the charging session.
During the fast charging your EV will be charged with the max available charging
power as fast as possible. Max power is set by the installer based on the grid
capabilities where charging station is installed.
When Interactive charging is chosen charging schedule will be modified based on
the inserted departure time or if it is not inserted based on historic session data.
Historic data is used from the first charging session onward. More charging session
means more accurate session prognosis and schedules. Charging schedule will be
created based on electricity prices, other loads and PV production to make sure EV
is charged in appropriate time while taking in consideration other constraints.
CHARGING PROCEDURE
Step1: WAKE
When you come to the charging station its LCD screen will likely be in the screen
saver mode. You can wake it up by simply tapping the screen.
