Police in the German state of Baden-Württemberg have launched a pilot project using a battery-buffered fast-charging system from ADS-TEC Energy to support electric patrol vehicles at a motorway police station in Pforzheim, addressing limited grid capacity without costly infrastructure upgrades.
The installation at the Pforzheim traffic police unit uses ADS-TEC Energy’s ChargePost system, which combines high-power DC charging with integrated battery storage. The unit can deliver up to 300 kilowatts of charging power to a single vehicle, or two simultaneous charging sessions at 150 kW each, while drawing comparatively modest power from the local electricity grid.

Battery-buffered charging allows energy to be stored gradually and then discharged rapidly when vehicles need to be turned around quickly. This is particularly relevant at the Pforzheim site, which operates on one of Germany’s busiest motorway corridors and requires patrol vehicles to remain available around the clock.
Baden-Württemberg’s police fleet currently includes around 630 electric vehicles, accounting for roughly 12% of its total fleet of about 5,400 vehicles. State officials say the pilot will help assess how high-power charging systems perform under real operational conditions for emergency services, where downtime can directly affect response capability.

Thomas Strobl, Deputy Minister-President and Minister of the Interior of Baden-Württemberg, said, “We are one of the safest regions in Germany, and we believe in investment to continue our success. This includes the largest recruitment drive in our history and the latest technologies – including this project. What makes this ADS-TEC Energy solution special is its integrated battery storage, which enables EV charging at high power even at locations with limited grid capacity. This allows us to stress test EVs in real motorway conditions.”
Strobl added “This project represents the next phase in a journey that we started 15 years ago. Around 630 – roughly 12% – of our 5,400 police vehicles are already electric and the Pforzheim traffic police unit will now put the new fast charging system and EVs through their paces as we set the course for future-proofed policing.”
“Charging infrastructure is critical infrastructure – especially when emergency vehicles must be available around the clock,” said Thomas Speidel, CEO of ADS-TEC Energy. “Our systems are developed and manufactured in Germany and meet high standards in cyber security, operational safety and resilience. With our many years of experience in battery-buffered fast charging, we are the ideal partner for demanding public sector use cases. We greatly value our partnership with the Baden-Württemberg police and are proud to support the motorway police in their daily operations.”
The ChargePost system incorporates a 201 kilowatt-hour lithium-ion battery and is designed to operate on existing grid connections, avoiding the need for transformer upgrades or new high-voltage lines. ADS-TEC Energy said the compact design allows installation at legacy facilities where space and grid capacity are constrained.
The pilot forms part of Baden-Württemberg’s longer-term push to electrify public-sector fleets, an effort that has been underway for more than a decade. Officials said the trial will also examine vehicle performance, charging reliability and operational resilience under continuous motorway patrol use.
ADS-TEC Energy said its charging systems are developed and manufactured in Germany and are designed to meet elevated requirements for cybersecurity, data sovereignty and operational robustness, standards that are increasingly relevant for charging infrastructure used by emergency services and other critical public operators.
