Siemens has launched the SICHARGE FLEX, a groundbreaking next-generation electric vehicle (EV) charging system capable of delivering power from 480 kW up to an impressive 1.68 megawatts (MW) and current capacities of up to 1,500 amperes (A). Unveiled at Busworld 2025, this state-of-the-art charging solution introduces dynamic power distribution and modular dispenser configurations supporting both Combined Charging System (CCS) and Megawatt Charging System (MCS) standards, marking a significant leap forward for large-scale, high-speed EV charging technology.
Revolutionizing Power Delivery with Dynamic Distribution
At the core of SICHARGE FLEX is its pioneering fully dynamic power distribution system that intelligently allocates electricity across multiple charging points based on real-time vehicle demand. This innovation guarantees that each outlet receives precise power increments ranging from 80 kW to as high as 1.68 MW, optimizing energy efficiency and throughput. Such flexibility accommodates various vehicle types, from passenger cars to the heaviest electric trucks and buses, all while maintaining optimal performance and minimizing energy waste. This adaptability helps fleet operators, charge point operators (CPOs), and OEMs optimize infrastructure returns by future-proofing their investments against evolving market needs.
Modular Design and Industry-Leading Power Density
SICHARGE FLEX’s modular dispenser architecture allows for easy customization and scalability. The system supports up to four MCS charge points in a single setup, further enhancing flexibility for expansive fleet and depot environments. Dispensers can be placed up to 300 meters away from the central power cabinet, and their compact footprint (as low as 0.1 m² for CCS and 0.2 m² for MCS options) accommodates space-constrained installation sites. Remarkably, the system boasts an industry-leading power density of 656 kW per square meter, achieved through innovative front-in, front-out cooling technology that enables wall-mounted placements—ideal for urban and depot applications where real estate is costly.
Use Cases and Early Adoption
The launch of SICHARGE FLEX at Busworld 2025 coincides with its first customer installation for OMV at the strategic Kufstein location in Austria, a vital corridor connecting Germany and Italy. OMV’s deployment will initially feature six fast-charging points servicing passenger vehicles alongside electric trucks and buses, with plans to expand to ten outlets post grid enhancement. This project underlines the system’s suitability for high-demand, multi-vehicle environments requiring rapid, reliable charging access with seamless user experience.
SICHARGE FLEX is adaptable to a broad spectrum of applications, including fleet depots, logistics hubs, highway fast-charge stations, and public transportation charging sites. Its capabilities enable operational excellence in scenarios demanding quick turnaround times, balancing grid load while providing uninterrupted power to diverse electric vehicle fleets.
Smart Infrastructure and Sustainability
Siemens has integrated SICHARGE FLEX into its broader eMobility ecosystem, including cloud-based monitoring and management via Sifinity Control. Operators benefit from real-time visibility, remote diagnostics, and customizable system configurations tailored to specific site requirements. Combined with DepotFinity’s smart energy management, SICHARGE FLEX optimizes fleet charging even under constrained grid capacity, reducing infrastructure upgrade costs while enhancing sustainability.
Environmentally, the system supports zero-emission mobility by facilitating the rapid adoption of electric transit solutions, thereby significantly reducing carbon footprints in transport sectors reliant on heavy-duty vehicles. Siemens’ commitment extends to cybersecurity with robust encryption and secure boot processes, ensuring protected and reliable charging operations.
The Road Ahead: Transforming E-Mobility Infrastructure
SICHARGE FLEX sets a new industry benchmark for megawatt-scale EV charging solutions, blending technical innovation with practical deployment flexibility. It addresses critical challenges such as charging speed, space constraints, user convenience, and future scalability. This pioneering system exemplifies Siemens’ leadership in smart infrastructure and its dedication to accelerating the global transition to sustainable mobility. As electric vehicle adoption explodes, innovations like SICHARGE FLEX will be essential in supporting the mass electrification of fleets and public transport, enabling greener, cleaner cities around the world.
In conclusion, Siemens SICHARGE FLEX heralds a future where high-capacity EV charging is efficient, reliable, and adaptable to the complex needs of evolving electric mobility ecosystems. Its launch marks a crucial milestone in the quest for sustainable transportation solutions that meet the demands of tomorrow’s connected and electrified world.
