How to Connect OCPP-Compatible EV Chargers with the Scharr App

What is OCPP?

OCPP (Open Charge Point Protocol) is an open standard for communication between EV chargers and central management systems. Many EV charger manufacturers support OCPP, making it possible to connect various charger brands through a single integration.

Preconditions:

  • Ensure your EV charger supports OCPP 1.6.
  • Your charger must be configured to connect to an OCPP backend.
  • Have your charger’s connection details ready (Charge Point ID).

Connecting Your OCPP Charger with Scharr

To connect your EV charger, enter the following URL in the OCPP settings in your charger vendor’s app. You will find the OCPP URL in Scharr when adding an OCPP charger.
