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.
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

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.

Windows
To determine if your computer is in the same network as charging
station ping the station using the CMD command ping with the IP of
the station. You can change computer network in the network
settings.
To ping the station, connect to Command Prompt by searching for it
in windows search functionality.
Figure 20: Search for CMD using windows search functionality
Figure 21: Open Command Prompt
In the Command Prompt write ping and IP address you would like to
ping (eg. ping 192.168.1.190).

Change the computer network settings
If you can't ping charging station using your computer you won't be
able to connect to the charging station's web interface. You will have
to change your computer's IP and network settings in order to
configure the charging station.
Windows
In order to change the network of your computer in Windows OS you

panel. How to locate the settings is shown below in the figure.
Once you find the Internet protocol Version 4 (TCP/IPv4) press
“Properties” this will show you a new window where you can type
new IP address of the computer that is in the same network segment
as the station’s IP.

If the station default IP is 192.168.1.250 you should change IP
address to 192.168.1.1. Last bolded number can be random as long
as it is not used by some other appliance in the network. For the
subnet mask you should write 255.255.255.0. You will now be able
to ping the station as it is shown above.
