Build Status


SteVe was developed at the RWTH Aachen University and means Steckdosenverwaltung, namely socket administration in German. The aim of SteVe is to support the deployment and popularity of electric mobility, so it is easy to install and to use. SteVe provides basic functions for the administration of charge points, user data, and RFID cards for user authentication and was tested successfully in operation.

SteVe is considered as an open platform to implement, test and evaluate novel ideas for electric mobility, like authentication protocols, reservation mechanisms for charge points, and business models for electric mobility. SteVe is distributed under GPL and is free to use. If you are going to deploy SteVe we are happy to see the logo on a charge point.

Charge Point Support

Electric charge points using the following OCPP versions are supported:

  • OCPP1.2S
  • OCPP1.2J
  • OCPP1.5S
  • OCPP1.5J
  • OCPP1.6S
  • OCPP1.6J

For Charging Station compatibility please check:

System Requirements

SteVe requires

  • JDK 11 (both Oracle JDK and OpenJDK are supported)
  • Maven
  • At least MySQL 5.7.7 (MariaDB 10.2.1 or later works as well) as database (Note: MySQL 8.x is not supported yet)

to build and run.

SteVe is designed to run standalone, a java servlet container / web server (e.g. Apache Tomcat), is not required.

Configuration and Installation

  1. Database preparation:

    Make sure MySQL is reachable via TCP (e.g., remove skip-networking from my.cnf). The following MySQL statements can be used as database initialization (adjust database name and credentials according to your setup):

    CREATE DATABASE stevedb CHARACTER SET utf8 COLLATE utf8_unicode_ci;
    GRANT ALL PRIVILEGES ON stevedb.* TO 'steve'@'localhost' IDENTIFIED BY 'changeme';
    GRANT SELECT ON mysql.proc TO 'steve'@'localhost' IDENTIFIED BY 'changeme';

    Important: Make sure that the time zone of the MySQL server is the same as the time zone of SteVe. Since UTC is strongly recommended by OCPP, it is the default in SteVe and you should set it in MySQL, accordingly.

  2. Download and extract tarball:

    You can download and extract the SteVe releases using the following commands (replace X.X.X with the desired version number):

    tar xzvf steve-X.X.X.tar.gz
    cd steve-X.X.X
  3. Configure SteVe before building:

    The basic configuration is defined in

    For advanced configuration please see the Configuration wiki

  4. Build SteVe:

    To compile SteVe simply use Maven. A runnable jar file containing the application and configuration will be created in the subdirectory steve/target.

    # mvn package
  5. Run SteVe:

    To start the application run (please do not run SteVe as root):

    # java -jar target/steve.jar

First Steps

After SteVe has successfully started, you can access the web interface using the configured credentials under:


The default port number is 8080.

Add a charge point

  1. In order for SteVe to accept messages from a charge point, the charge point must first be registered. To add a charge point to SteVe select Data Management >> Charge Points >> Add. Enter the ChargeBox ID configured in the charge point and confirm.

  2. The charge points must be configured to communicate with following addresses. Depending on the OCPP version of the charge point, SteVe will automatically route messages to the version-specific implementation.

    • SOAP: http://<your-server-ip>:<port>/steve/services/CentralSystemService
    • WebSocket/JSON: ws://<your-server-ip>:<port>/steve/websocket/CentralSystemService/<chargeBoxId>

As soon as a heartbeat is received, you should see the status of the charge point in the SteVe Dashboard.

Have fun!

If you are in the EU and offer vehicle charging to other people using SteVe, keep in mind that you have to comply to the General Data Protection Regulation (GDPR) as SteVe processes charging transactions, which can be considered personal data.
