Munich-based EcoG and Siemens have partnered to implement a new generation of electric vehicle charger software. EcoG became an official Siemens Product Partner for SIMATIC automation systems as part of the collaboration.
Why it matters
More than 50 manufacturers of DC fast chargers use technology from both companies, so the partnership could affect a wide base of charging hardware. The collaboration is positioned around upcoming requirements, including EU rules for charging points.
More than 50 manufacturers of DC fast chargers use technology from EcoG and Siemens, according to the companies. The source does not provide sales, performance, or deployment figures for the upgraded systems.
The players
EcoG
EcoG is a Munich-based company that handles system integration and field operations for EV fast charging hardware, and whose CEO and cofounder is Jörg Heuer.
Siemens
Siemens is a global industrial technology company whose Digital Industries division supplies the SIMATIC automation systems on which customers' charging systems are built.
The details
The EcoG operating system lets manufacturers upgrade chargers without redeveloping them, while the SIMATIC architecture remains in place and only the charging module is replaced. The system supports Plug & Charge, the Megawatt Charging System for heavy-duty vehicles, and billing that complies with German calibration law (Eichrecht).
Timeline
2027: The EU will require new charging points to support ISO 15118-20.
Roadmap
The upgrade path is designed around the EU's requirement that new charging points support ISO 15118-20 starting in 2027, a standard the partnership is intended to help manufacturers meet. It also addresses the Cyber Resilience Act, positioning the EcoG and Siemens approach within the continuing regulatory push for secure, standardized EV charging.
Charger operators may be able to upgrade existing DC fast chargers to the EcoG operating system rather than replacing hardware, since only the charging module is swapped. The system's support for Plug & Charge and German-compliant billing affects how drivers pay and connect at upgraded stations.
The takeaway
Software-based upgrades that keep existing automation hardware in place may help charging networks meet new standards without full replacement. Operators should watch the 2027 EU deadline for ISO 15118-20 when planning charger updates.
What happens next
The EU's requirement that new charging points support ISO 15118-20 takes effect in 2027.
