YOUR FIRST 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.
