Reference project

Transformation at the filling station

JET and Voltfang demonstrate the future of electromobility in Hamburg: A 300 kW HPC fast charging station with Voltfang battery storage enables ultra-fast charging – without any expensive grid expansion.

Fast charging station at JET

  • Company: JET
  • Location: Hamburg
  • Industry: Electric mobility / Charging infrastructure

Benefits for JET

Future-proof mobility
Transforms traditional gas stations into modern charging and mobility hubs
No network expansion necessary
Saves high investment costs and long approval times
ultra-fast charging
Battery storage ensures stable supply to all charging points
CO₂ reduction immediately measurable
Lower emissions through the use of requalified electric car batteries

Implemented use case

The battery storage serves as a power buffer for an HPC charging station to enable ultra-fast charging despite a limited grid connection. This solution is particularly relevant for petrol station locations or other charging hubs where the power grid is not sufficiently dimensioned and grid expansion would be costly or time-consuming.

Charging station infrastructure
Power to the point

Aim of the project

JET wanted to make its Hamburg filling station location fit for electromobility and provide 300 kW charging power – without having to expand the existing 80 kW grid connection. The aim was to avoid grid congestion, reduce costs and approval times and at the same time pave the way for climate-friendly mobility hubs.

Our customized solution

The Voltfang second-life storage system installed has a capacity of 90 kWh and an output of 45 kW. It reliably stores the PV electricity generated and provides this flexibly for the packaging machines and charging infrastructure at the site.
