OCPP

Open Charge Point Protocol (OCPP) is a standard for communication between a Charging Station and their CSMS (Charging Station Management System, the central backend). The Teleport can act as an OCPP Local Controller. The charging stations then connect to the Teleport and the Teleport connects to the CSMS.

Any charging station that supports OCPP 1.6J or OCPP 2.0.1 with SmartCharging is supported. Often that is mentioned in the documentation of the charging station. When certified, the model is also listed at OCPP certified companies.

Required Information Checklist

The following information is needed to correctly configure the Teleport:

1. The OCPP identity (string) of each charging station and preferably their static local IP addresses.
2. The URL of the CSMS (central backend) to which the charging station is currently directly connected.
3. Asset Specifications: Brand, exact model, nominal power rating, and type (AC or DC) etc.
4. Manufacturer’s OCPP Implementation Manual (if available).

Required Configuration Checklist

The following configuration steps are needed to succesfully deploy the Teleport as a local controller:

1. The Teleport and the chargers must be deployed on the exact same local network subnet.

2. The server URL (or CSMS URL) in the charging station must be set to the IP address of the Teleport. Typically this is in the form of an URL, prefixed with ws:// or wss://, for example wss://192.168.1.12/, depending on the encryption.

3. In case TLS encryption (using the wss:// prefix) is desired for local communication between the charging station and Teleport the public root certificate of the Teleport must be uploaded to each charging station. This is recommended, but a bit more work to set up. We will supply the public root certificate to you before installation.

Note

Modifying a charger’s internal OCPP settings often requires some manufacturer-specific configuration actions. This could mean that specific steps have to be performed on, for example, local administrative web interfaces, windows applications or on the physical display of the charger.

Note

Many brands have slight peculiarities on their OCPP integration. If we don’t have experience with your brand yet it might take us some time to get this up and running.

Decomissioning

In most situations the Teleport is configured to set a fallback limit of 0W on the charging stations, to avoid going over a grid limit when the connection with the charging station is lost. These fallback profiles have profileId 201 for the first EVSE, 202 for the second EVSE and so on. If you decomission the Teleport these fallback schedules need to be cleared. We can do that for you in case the Teleport still has connection to the charging station. Otherwise you can send an empty ClearChargingProfile instruction to the Charging Station from the CSMS. Please reach out if you need help with this.
