German multinational technology company Siemens has unveiled SICHARGE FLEX, its next-generation distributed electric vehicle (EV) charging system designed to support the growing demand for high-capacity and flexible charging infrastructure.
The system offers modularity and scalability, enabling operators to adapt installations for a range of use cases, from fleet depots to public charging hubs.
The launch highlights Siemens’ continued investment in EV infrastructure for what it calls the “megawatt era” of charging, where larger vehicles such as buses and heavy goods vehicles require rapid, high-power systems.
High-capacity and adaptable charging design
At the core of SICHARGE FLEX is a dynamic power distribution system that allocates energy across multiple charging points in real time.
This approach allows each outlet to deliver the required power based on vehicle demand, with a total system capacity ranging from 480 kW to over 1.68 MW.
The system supports both CCS and MCS charging standards, providing up to four MCS charge points from a single unit and delivering up to 1,500 A of charging current.
Siemens said the design achieves high power density – up to 656 kW per square metre – while maintaining a compact footprint suitable for space-limited sites.
Dispensers can be installed as far as 300 metres from the central cabinet and configured as floor, wall, or overhead-mounted units.
Markus Mildner, CEO of eMobility at Siemens Smart Infrastructure, says, “The introduction of SICHARGE FLEX marks a significant milestone in our journey to build a comprehensive and sustainable e-mobility ecosystem.
“It empowers customers to scale operations, optimise energy use, and contribute to a cleaner, electrified world.”
Integration, management, and energy efficiency
SICHARGE FLEX integrates with Siemens’ eMobility ecosystem and can be managed through the cloud-based Sifinity Control platform, providing remote monitoring and configuration.
The system is also compatible with DepotFinity’s smart energy management, which balances load distribution for fleet operators and helps reduce grid upgrade costs.
Early adopters include OMV, an Austria-based charge point operator and mobility service provider.
The company will install SICHARGE FLEX at its site in Kufstein, Austria, along the A12 corridor linking Germany and Italy.
The initial phase will include six charging points, with expansion to ten planned following local grid reinforcement.
Eric Schulze, Senior Vice President of Retail Mobility and Convenience at OMV, comments, “Our mission is to provide reliable, high-performance charging infrastructure that meets the demands of modern mobility.
“The new Kufstein site will serve passenger cars, electric trucks, and buses, combining fast charging, accessibility, and scalability.”
Sustainability and cybersecurity
Siemens states that SICHARGE FLEX supports efficient energy use and grid balancing, contributing to more stable and sustainable energy networks.
It also incorporates “Security by Design” principles, including encryption and secure boot mechanisms, to ensure data protection and system integrity.
The system was introduced at Busworld 2025 in Brussels and will be commercially available in 2026.
