4 OPERATION OF CHARGING STATION AND

CHARGING PROCEDURE

FIRST CHARGING STATION POWER UP

When you power up the charging station for the first time it can take
several minutes for station to get ready to start using it to charge EV.
Charging station is powered up automatically when it is connected
to the electricity. In the table below, you can see all the possible
events that can occur when you start the station and what should
you do in case something is wrong.

Etrel Inch | User Manual

Green light is
blinking

LCD is turned on
and charging
station is ready
to be used.

When the LCD
starts the logo
will be first
displayed and
after that you can
start using the
charging station.

LCD is turned on
but freezes and is
unresponsive.

Try resetting the
charging station. If
the problem
repeats there
might be a
problem with the
software. You
should call the
support.

You can read the
resetting
procedure in
chapter 6
Troubleshooting.

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.

Chargi ng proce dure

Step 1 : WA K E

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.

Screen saver mode can be chosen in the charging station’s web
interface. Three options exist: turned on all the time, it can be
blinking or turned off until touched. Description how to change this
setting can be found in the Etrel INCH configuration guide.

Step 2 : AU T H ORISA TION

Depending on the charging station authentication mode chosen
different screens will be shown that will need different actions from
user in order to continue with the charging session. What
authorization is allowed to be used can be setup in the charging
station’s web interface Configuration menu. Procedure is described
in the document Etrel INCH configuration guide.

Plug and charge mode

In the plug and charge mode user will see message to insert the

5 WEB INTERFACE

Charging station’s web interface allows you to connect to the
charging station platform to configure its settings as well as check
the charging session and station data, check the connectivity status
and errors description when they occur.

CONNECT TO WEB INTERFACE

Users can connect to the charging station web interface using the
charging station IP address. Default IP address can be found on the
information sticker on the inner part of the maintenance doors. IP of
the charging station can be manually changed. If you did this and
forgot the new created IP you can always revert back to the default
IP by resetting the charging station to the manufacturer settings
(procedure is described in chapter 6 Troubleshooting).

When IP address is written in the internet browser and the computer
is in the same local network you will be connected to the web
interface.

6 TROUBLESHOOTING

Etrel INCH charging station provides you quick access to the side
maintenance area to execute basic troubleshooting and to reset the
charging station in case there are some problems. You are also able
to reset the charging station straight from the web interface.

ACCESS TO THE SIDE MAINTENANCE AREA

Side maintenance area is protected by the maintenance doors.
Depending on the type of Etrel INCH charging station you are using,
two different doors are available. One with the regular key lock and
one with hex screw (2.5 mm). To access the area, you will need
either key or a hex screw driver.

Etrel Inch | User Manual

Important: RCD and Ocervurrent
protection element needs to be tested and
reset by pressing the button on the device
at least once per month. By doing this,
appropriate operation of RCD and
Overcurrent are ensured. If this is not done
the protected device can be dangerous to
users and potential malfunction can be
life-threatening.

On the inside of maintenance doors, you will find sticker with
technical information including basic charging station information,
model type and serial number. When support is contacted it is
important that you know the charging station model type so the
support can quickly help you solve the issue. This information can be
gathered on the web interface in the Diagnostics menu.

RESETING THE CHARGING STATION

Charging station can be reset by opening the side maintenance doors
and pressing the button inside the maintenance opening.

If you hold the button 4 s the charging station will respond with the
beep after which you will have options on the screen to check the IP
address of the station or to reset the station. You can do the basic
reset and factory reset, which will restore charging station’s factory
settings (username, password, default IP and other settings).

Figure 36: Reset button inside the maintenance opening

RESET AND TEST THE PROTECTION ELEMENTS

One protection element can be installed inside the charging station.
In order to ensure that the element is working properly you need to
test it. This should only be done if RCD or overcurrent protection is
installed inside the charging station.

RCD

The test button on the RCD unit allows user to verify the correct
operation of the device by passing a small current through the RCD
unit. This simulates a fault by creating an imbalance in the sense
coil. If the RCD does not trip when this button is pressed, then the
device must be replaced. You have to change the device also when

Etrel Inch | User Manual

the fid was tripped but you can’t move the switch back into active
position. To change the RCD please call the support number.

Figure 37: RCD test button

Overcu rrent pr otecti on

Check the overcurrent protection (if installed) once a year for any
visible damages on the surface. If the overcurrent protection is
tripped and the switches can’t return to the active position
something is wrong with the protection and needs to be changed by
maintenance crew.

USING WEB INTERFACE FOR
TROUBLESHOOTING

You can also use web interface for trouble shooting like it is
described in the diagnostics section of chapter 4 Web interface.
