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:
For Charging Station compatibility please check: https://github.com/RWTH-i5-IDSG/steve/wiki/Charging-Station-Compatibility
- JDK 11 (both Oracle JDK and OpenJDK are supported)
- MariaDB 10.2.1 or later. MySQL 5.7.7 or later works as well, but especially MySQL 8 introduces more hassle. We suggest MariaDB 10.3.
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
Important: Make sure that the time zone of the MySQL server is the same as the time zone of SteVe. Since
UTCis strongly recommended by OCPP, it is the default in SteVe and you should set it in MySQL, accordingly.
Make sure MySQL is reachable via TCP (e.g., remove
my.cnf). The following MySQL statements can be used as database initialization (adjust database name and credentials according to your setup).
For MariaDB (all versions) and MySQL 5.7:
CREATE DATABASE stevedb CHARACTER SET utf8 COLLATE utf8_unicode_ci; CREATE USER 'steve'@'localhost' IDENTIFIED BY 'changeme'; GRANT ALL PRIVILEGES ON stevedb.* TO 'steve'@'localhost'; GRANT SELECT ON mysql.proc TO 'steve'@'localhost';
For MySQL 8:
CREATE DATABASE stevedb CHARACTER SET utf8 COLLATE utf8_unicode_ci; CREATE USER 'steve'@'localhost' IDENTIFIED BY 'changeme'; GRANT ALL PRIVILEGES ON stevedb.* TO 'steve'@'localhost'; GRANT SUPER ON *.* TO 'steve'@'localhost';
Note: The statement
GRANT SUPER [...]is only necessary to execute some of the previous migration files and is only needed for the initial database setup. Afterwards, you can remove this privilege by executing
REVOKE SUPER ON *.* FROM 'steve'@'localhost';
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):
wget https://github.com/RWTH-i5-IDSG/steve/archive/steve-X.X.X.tar.gz tar xzvf steve-X.X.X.tar.gz cd steve-X.X.X
Configure SteVe before building:
The basic configuration is defined in main.properties:
- You must change database configuration
- You must change the host to the correct IP address of your server
- You must change web interface credentials
- You can access the application via HTTPS, by enabling it and setting the keystore properties
For advanced configuration please see the Configuration wiki
To compile SteVe simply use Maven. A runnable
jarfile containing the application and configuration will be created in the subdirectory
# mvn package
To start the application run (please do not run SteVe as root):
# java -jar target/steve.jar
If you prefer to build and start this project via docker (you can skip the steps 1 and 3, 4, 5 above), this can be done as follows:
docker-compose up -d
The web interface will be accessible at:
First build your image, and push it to a registry your K8S cluster can access. Make sure the build args in the docker build command are set with the same database configuration that the main deployment will use.
docker build --build-arg DB_HOST= --build-arg DB_PORT= --build-arg DB_USERNAME= --build-arg DB_PASSWORD= --build-arg DB_DATABASE= -f k8s/docker/Dockerfile -t <IMAGE_NAME> .
docker push <IMAGE_NAME>
Then go to
k8s/yaml/Deployment.yaml and change
### YOUR BUILT IMAGE HERE ### to your image tag, and fill in the environment variables with the same database connection that you used at build time.
After this, create the namespace using
kubectl create ns steve and apply your yaml with
kubectl apply -f k8s/yaml/Deployment.yaml followed by
kubectl apply -f k8s/yaml/Service.yaml
To access this publicaly, you'll also have to setup an ingress using something like nginx or traefik.

You'll find a tutorial how to setup SteVe in AWS using Lightsail here: https://github.com/RWTH-i5-IDSG/steve/wiki/Create-SteVe-Instance-in-AWS-Lightsail
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
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.
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.
As soon as a heartbeat is received, you should see the status of the charge point in the SteVe Dashboard.
- Connector Status
- Data Management - Charge Points
- Data Management - Users
- Data Management - OCPP Tags
- Data Management - Reservations
- Data Management - Transactions
- Operations - OCPP v1.2
- Operations - OCPP v1.5
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.
