Nurtingen, Germany & SALZBURG, Austria,Nov 28, 2025 — ADS-TEC Energy (NASDAQ: ADSE), a global leader in battery-based energy storage and fast-charging systems, and Salzburg AG, a regional energy and infrastructure provider in Austria, announced the successful technical prequalification of the ChargePost fast charging system for participation in the Austrian ancillary services market. Salzburg AG has integrated ChargePost into its virtual power plant, where it now contributes to maintaining grid stability.
The prequalification confirms that ChargePost is capable of providing short-term power adjustments to help stabilize grid frequency. This represents a new category of fast charging infrastructure: one that not only serves electric vehicles but adds value in an increasingly flexible and decentralized energy system.
ChargePost combines ultra-fast DC charging of up to 300 kW with up to 201 kWh of battery capacity, even when connected to the standard low-voltage grid. Its bidirectional storage and intelligent energy management enable:
Peak shaving capabilities
Reduced grid connection costs
Stable operation and full-power EV charging at any time
These capabilities illustrate how battery-integrated fast charging can operate efficiently and reliably, even in areas with limited local grid capacity.
At a joint event in Salzburg on November 25, Thomas Speidel, founder and CEO of ADS-TEC Energy, together with Salzburg AG board members Michael Baminger and Herwig Struber, marked ChargePost’s successful prequalification.
Thomas Speidel said, “To accelerate growth, fast charging has to evolve from being a cost center. With intelligent buffering and stable grid behavior, systems like ChargePost open up new flexibility in the operation of charging infrastructure. Our work with Salzburg AG shows how high-power charging and grid stability can go hand in hand.”
Further expansion of the collaboration
ADS-TEC Energy has also won a tender from Salzburg AG for 20 additional ChargePost systems. This commitment demonstrates the importance of the two companies’ strategic partnership as they continue to build-out battery-supported fast charging infrastructure in the region.
A technology milestone that delivers new market opportunities
ChargePost’s prequalification demonstrates that it meets the criteria required to provide ancillary services – a capability traditionally reserved for standalone, large-scale battery storage systems. This compact multi-use architecture enables fast charging and grid support in a single system, offering utilities and charging operators a scalable approach that can be replicated across additional regions and markets.
