5. Downloading the go-e App and Connecting the Wallbox

In order to take the go-e wallbox into operation you need to connect the go-e app with the go-e wallbox. For this download the go-e app from Google Play or App Store.

Connecting the Wallbox with the go-e App

1. If necessary deactivate mobile data on the display unit and finish active Wi-Fi connections.
2. Scan the QR code of the reset card or manually search for the network of the wallbox in the settings of the display unit (indicated as go-e-xxxxx).

A connection with the hotspot of the wallbox is established.
In case of a manual connection you need to enter the password which is printed on the reset card under hotspot key.

3. Open the go-e app.
4. If the page Charging is indicated, the wallbox can be already operated locally through the go-e app. Otherwise select the wallbox in the go-e app.

NOTICE

In order to perform a HV Battery diagnostics PRO, the wallbox needs to be connected with the Internet.
Perform the steps under Registering the Wallbox [} 27] to connect the wallbox with a Wi-Fi network.

6. Registering the Device via the mega macs

Proceed as follows to make the device registration via the mega macs and to register the wallbox at Battery Quick Check:

1. Open the mega macs menu with , go to> Settings > HV Battery diagnostics PRO > Register mega macs to activate HV Battery diagnostics PRO.

The message “Device successfully registered” appears in the mega macs if the device registration has been completed successfully.

2. Use the button >Open page for Battery Quick Check< (possible only in the browser) or the QR code to call up the Battery Quick Check App.

NOTICE
To open the Battery Quick Check App, call up the SDI user interface manually with the Google Chrome/Safari browser (see Putting the mega macs X into Operation [} 22]).

The portal of Battery Quick Check is called up.

3. Add a new wallbox as described in section Registering the Wallbox [} 27].

Ensure the Wi-Fi connection between the go-e App and the workshop.

NOTICE
In order to perform a HV Battery diagnostics PRO, you need to create a user and you need to activate the check box Authorization for HV Battery diagnostics PRO.
Perform the steps in section Creating a New User with the mega macs [} 23] to create a user and to activate the Authorization for HV Battery diagnostics PRO.

Now you can do a HV Battery diagnostics PRO provided that a user has been created.
After having completed the HV Battery diagnostics PRO you will receive a certified status report with the battery’s SoH (State of Health) by e-mail.

7. Registering the Wallbox

In order to perform a HV Battery diagnostics PRO, you need to register a go-e wallbox and you need to connect it with theback-end of Battery Quick Check. The communication with the go-e wallbox uses the OCPP protocol (Open ChargePoint Protocol).

(1) Register the go-e wallbox in the Battery Quick Check app

THe following link provides further information about the go-e Wallbox: https://go-e.com/de-de/support/anleitungen

1. Use the Battery Quick Check App to call up https://portal.batteryquickcheck.com and select >Chargers<.
2. Go to Settings and select Add new charger (wallbox).

3. Enter the name of the go-e charger used and the type Go-e (OCPP).

4. Select the installation type and determine the maximum charging current for the go-e wallbox.

5. Select >Save< to receive the password for the go-e wallbox.

Ensure that the password will be saved. It is indicated once only.

6. Push the arrow symbol on the right to view the details of the wallox and the user name. Copy the password link(wss://BENUTZERNAME:PASSWORT@websocket.batteryquickcheck.com) or save it and enter it in the go-e app.

Ensure that there is a colon between the user name and the password.

(2) Connect the go-e wallbox with the go-e app

1. If necessary deactivate mobile data on the display unit and finish active Wi-Fi connections.

2. In order to connect with the hotspot of the wallbox, either scan the QR code on the reset card (possibly requires anexternal app) or manually search for the network of the wallbox in the settings of the display unit (indicated as go-e-xxxxxx).

In case of a manual connection you need to enter the password which is printed on the reset card underhotspot key.

3. Open the go-e app.

If the page Charging is indicated, the go-e wallbox can be already operated locally through the app.
If the page Charging is not indicated, then select the go-e wallbox previously in the app.

(3) Connect the go-e wallbox with a Wi-Fi network

1. Select >Internet< and then the Wi-Fi network for the go-e wallbox under the available Wi-Fi networks.

2. Ensure that the go-e wallbox is connected to the Internet.

NOTICE

The go-e wallbox cannot be connected or operated with 5 GHz Wi-Fi networks. Please find more detailed
information and solutions under https://go-e.com/de- de/support/troubleshooting.

(4) Make sure that the maximum charging current is set

1. Click to the circuit in which the current charging current limitation is displayed.

2. Move the slider of the charging current limitation all the way to the right (to the maximum value).
3. Save the settings with the save symbol top right.

(5) Make sure that the access control is deactivated

1. Use the go-e app and call up Settings > Access control and ensure that the authentication is set to Open.

2. Save the settings with the save symbol top right.

(6) Actualise firmware version

1. Select Settings > Internet settings > Firmware version.
2. Where necessary, install version 055.6 or higher (e.g. 055.7 Beta).
3. Click to Update firmware after having selected the corresponding version. The actualisation of the firmware can takesome time.

The wallbox will restart after the acualisation is completed.

(7) Set up OCPP settings

1. In the go-e app select Internet > OCPP.

2. Enter the OCPP server URL incl. user name and password (wss://BENUTZERNAME:PASSWORT@websocket.bat-teryquickcheck.com).
3. Go to Dummy card and activate Send dummy card.
4. Make sure that the Dummy card ID has the status no-card.
5. Save the settings with the save symbol top right.
6. Activate OCPP 1.6.
7. Save the settings with the save symbol top right.

If registration was successful the OCPP status will change to Connected.

7. Registering the WallboxHella

8. Restart the go-e wallbox to be sure that all settings are adopted. For this unplug and plug in the go-e wallboxagain.

(8) Generate new password

In the go-e wallbox settings you can generate a new password if necessary. Proceed as follows for that: 1.
Activate the check box Generate new password and save or copy the password again.

2. Perform the steps under (7) Set up OCPP settings again to adopt the settings.

8. Charging Current Limitation of the Wallbox

Important Notes

Use this setting option to limit the maximum charging current. Therefore, the duration of a HV Battery diagnostics PRO can take more time.
The one-off setting made will be saved. Therefore, the active charging current limitation will be indicated as a note when starting a HV Battery diagnostics PRO.
The maximum charging current of the wallbox (16 A or 32 A) will not be exceeded, even if the setting for the charging current limitation should be higher than the maximum charging current of the wallbox.
The setting of the charging current limitation will have an effect only if the wallbox is used for a HV Battery diagnostics PRO. The current for standard charging of electric vehicles is not affected by this setting.

When does a charging current limitation make sense?

Fuse blows out during charging procedure
The fusing of the electric supply is lower than the maximum possible charging current of the wallbox. The setting makes sense if an adapter cable from 32A to 16A of another manufacturer is used and if the adapter cable is not rec- ognized by the wallbox. Many wallboxes do recognize only original adapter cables of the wallbox manufacturer.
Abortion of the HV Battery diagnostics PRO due to inconsistent charging current (Error: SOH_CON-STANT_CHARGING_EXCEPTION)
Ensure the constant charging power during the charging procedure for a HV Battery diagnostics PRO. Charge man-agement systems or electric power consumers with high capacity can briefly reduce the charging power. The deacti-vation of charge management systems or cutting off electric power consumers with high capacity is the best solution for this issue. If the cutoff is not possible a reduction of the charging current can help to successfully perform the HV Battery diagnostics PRO. A reduction of the current limitation in intervals is recommended as the duration of the HV Battery diagnostics PRO increases with the reduction of the charging current limitation.

NOTICE

It is recommended to limit the charging current only if there is a reason for that.
