OCPP Charge Point Emulator

This project's goal is to allow users to emulate all of the features of OCPP (both 1.6 & 2.0.1) in order to allow easier testing and speed up local development, here is an overview of what has been implemented in the project so far

OCPP 1.6

  • Core (Done)
  • Firmware Management (Done)
  • Local Auth List Management (Done)
  • Reservation (Not Done)
  • Smart Charging (Semi Done)
  • Remote Trigger (Done)

OCPP 2.0.1

  • Currently under development, the OCPP 2.0.1 version is not yet fully implemented, but we're working on it.

How to run

If you're using Intellij IDEA, you can just run one of the two configurations that are saved in the .run folder

  • Run V16 for OCPP 1.6
  • Run V201 for OCPP 2.0.1

If you're just using the terminal, you can run the following command:

OCPP 1.6

./gradlew run v16:run

OCPP 2.0.1

./gradlew run v201:run

What's up with the 🤓?

Clicking the icon gives access to "message interception". The primary purpose is to have a high degree of control over which messages are sent and received by the charge point. That way it is possible to replicate potentially buggy behavior or custom implementations in a one-off manner without needing to change the actual programming of the charge point. For "normal operation" of the charge point the standard interface should be sufficient.

Also note that the message interception functions are not hooked up to the internal machinery of the charge point. For example, sending a StopTransaction message will not actually change the state of an ongoing charge to be stopped. That means using these functions also makes it very easy to put the charge point into a state that does not match up with what the CSMS is expecting, which can quickly lead to unexpected behavior.

Executables

If you only care about running the application you can find the latest release on the releases page we are currently building executables for Windows, Linux and MacOS.
