This manual provides instructions to enable the FlexiO integration in Alfen chargers, currently supported models are:

	Pro-Line
	Pro-Line Double Socket
	S-Line

Configuration of FlexiO requires that the modbus communication is enabled in each individual charger’s settings, the procedure can be executed locally (via MyEve app or ACE Service Installer) or remotely (via Backoffice).

It is required that the charger is connected via ethernet cable to the same network as the FlexiO device.

Alfen chargers do not support wireless connections.

Local configuration

With ACE Service Installer

The ACE Service Installer can be downloaded from

https://alfen.com/nl-be/search-downloads

1. Login with ACE credentials

These credentials can be requested by following the info in https://knowledge.alfen.com/space/IN/135922077/How+do+I+receive+login+details+for+the+ACE+Service+Installer+configuration+tool%3F

2. Identify the charger and login to it

Chargers will be listed on the left pane. Upon clicking on the relevant charger it will ask for credentials, use the password provided in the leaflet that came with the charger.

3. Check for the Active Load Balancing (ALB) feature

If the Active Load Balancing feature is unavailable or locked you will need to purchase it from the charger seller, this feature is required to pair the charger with the FlexIO platform.

4. Enable Active Load Balancing

To enable ALB the following values have to be inputted:

• Active Load Balancing: Checked

• Data Source: Energy Management System

• Safe current (A): This value should be set to the desired safe value that will be used if FlexIO loses connection to your charger.

• Allow 1- and 3-phased charging: Check this box if your charger is installed with 3-phases.

If the charger was previously configured for P1 or modbus meter communication (not EMS), it is required to completely reset the configurations before setting the Data Source to Energy Management System. If this is not done, the charger can persist the older configuration (P1 or modbus Meter) instead of communicating with the FlexIO platform.

Caution

Go to the TCP/IP EMS and set it has in the picture, i.e. Mode = Socket and ValidityTime (s) = 60.

With MyEve app

The MyEve app is available in the following app stores:

• Play Store (Android) 🔗

• App Store (Apple iOS) 🔗

• Microsoft Store (Windows 10 and 11) 🔗

1. Check for the Active Load Balancing (ALB) feature

Start by selecting the charger you want to configure from the MyEve app, then click on the ADVANCED tab and go to General ⇒ License Key.

If the Active Load Balancing feature is unavailable or locked you will need to purchase it from the charger seller, this feature is required to pair the charger with the FlexIO platform.

2. Enable Active Load Balancing

On the ADVANCED tab, go to Load balancing ⇒ Active Load Balancing. The following values have to be inputted:

• Active Load Balancing: Checked

• Data Source: Energy Management System

• Safe current (A): This value should be set to the desired safe value that will be used if FlexIO loses connection to your charger.

• Allow 1- and 3-phased charging: Check this box if your charger is installed with 3-phases.

Then, on the ADVANCED tab, go to Load balancing ⇒ Energy Management System, and set the values as in the next picture, i.e. Mode = Socket and ValidityTime (s) = 60.

Remote configuration

Remote configuration must be done via the configured backoffice communication, if available.

In the current Alfen chargers implementation the 1- and 3- phase EMS controlled switching must be activated locally, this is cannot be activated via backoffice.

The system will still work with a remote configuration but the potential will be limited as a 3-phased charged can’t be configured to use just 1 phase when needed.

1. Check for the Active Load Balancing (ALB) feature

Configuration Keys

The content of UnlockedFeatures key must show the Active Load Balancing feature as unlocked, otherwise you need to upgrade the license. ALB is mandatory for communication with the FlexIO platform.

2. Enable Active Load Balancing

To enable ALB and FlexIO communication the following values must be configured:

When configuring via backoffice, the Backoffice OCPP key is the key that must be set to the respective value. The ACE Service Installer Entry is just shown to provide a aid in comparing with the local configuration instructions.
