Schneider EVlink Pro AC

Supported devices: Schneider EVlink Pro AC.

Our EMS supports the Schneider EVlink Pro AC charging station over Modbus TCP, so charging power is steered along with the rest of the site instead of running on its own.

Model Current type Connectors
EVlink Pro AC AC 1

The integration communicates over Modbus TCP (default port 502, default unit id 1).

EMS functionality

  • Charging power control: the charging current is steered per connector, so charging follows the available power at the grid connection instead of a fixed maximum.
  • Load balancing: the charger takes part in the site load management. Charging is curtailed first when a (sub-)meter approaches its limit, before controllable loads are shed.
  • Session monitoring: charging state, delivered power and energy are read back and shown on the device page and in the EV charging dashboard.
  • Connector faults: a faulty charging connector reported by the station is raised as an incident, so a charge point that refuses to charge does not go unnoticed.

Setup

  1. Wiring and startup

    Complete the electrical installation and switch on the charging station. Verify that the residual current device and the circuit breaker protecting the charge point are active.

  2. Network

    Connect the charger to the same network as the Voltmasters controller and give it a fixed IP address in that subnet. Make sure port 502 is reachable between the controller and the charger.

  3. Enable Modbus TCP

    In the configuration interface of the charging station, enable Modbus TCP and note the unit id and port. Our EMS uses unit id 1 and port 502 by default.

    Restart the charging station after changing the network or Modbus settings, so the new configuration takes effect.

  4. Add the device in Voltmasters

    Add a new device of type EV charger, brand Schneider, model EVlink Pro AC, and fill in the IP address, port and unit id of the charger.

    Load balancing is set per connector for this model.

  5. Verify

    Start a charging session and check on the device page that the charging state and the delivered power come in, and that the charger follows a lowered power limit.
