From the Creators of SteVe

Your Chargers. Your Data.
Zero Lock-In.

Powerfill is built by the team behind SteVe, the world's most popular open-source OCPP server. We're committed to open standards, community-driven development, and giving you full control of your charging infrastructure.

OUR STORY

From University Project to Global Standard

SteVe (Steckdosenverwaltung - German for "socket administration") started at RWTH Aachen University in 2013. What began as a research project has grown into the go-to open-source OCPP server used by operators worldwide.

After over 10 years of maintaining SteVe, we created Powerfill to offer enterprise features while continuing our commitment to the open-source community. SteVe will always remain free and open.

With Powerfill's financial backing, SteVe receives ongoing development, security updates, and new features. The two platforms grow together - open-source fundamentals in SteVe, enterprise capabilities in Powerfill.
