Requirements to Enable Autocharge on Alfen EV Chargers

System Requirements for Autocharge

To enable Autocharge on Alfen EV chargers, the following components must be in place:

• Charger-to-Back Office Connection:
  • OCPP 1.6 or OCPP 1.6 Smart Energy (SE) protocol
• Charger Hardware:
  • Alfen Twin 5 (Plus) or other ISO15118-compatible models
  • Alfen Hardware Platform with firmware version 1.2.0 or higher
• License:
  • An active Autocharge license key

Software Configuration

To activate Autocharge:

1. Set the OCPP key “AutochargeEnabled” to “True”.
2. Ensure the EV supports fixed and unique idTags.
3. Use a mobile app or back-office system to initialize the EV idTag.

EV Compatibility Considerations

• Valid EV idTag: Must be unique and fixed.

• Invalid idTags: Autocharge will fail if the idTag is invalid.
• Rolling or Shared idTags: These can cause billing issues and should be excluded.

Alfen provides an exclusion list in the firmware to block incompatible vehicles. CPOs should report such EVs to Alfen for inclusion.
