Siemens unveils SICHARGE FLEX system for rapid fleet EV charging
Siemens has introduced its new SICHARGE FLEX electric vehicle charging system, offering power output capability from 480 kW up to 1.68 MW DC and dynamic flexibility for a variety of charging scenarios.
The SICHARGE FLEX system has been designed with modularity and scalability at its core, aiming to address the growing demand for robust charging solutions across fleet depots, highways, and other commercial locations. Featuring dynamic power distribution and diverse dispenser options, the system allows deployment in settings with varying spatial constraints and operational requirements.
Power and flexibility
The system delivers between 480 kW and 1.68 MW of power, with each charge point capable of receiving increments ranging from 80 kW. According to Siemens, the integrated dynamic power distribution ensures that electricity is output to each charging point in real time, based on vehicle demand. This approach supports both CCS and MCS charging standards, allowing a single configuration to provide up to four MCS charge points or a combination of CCS and MCS outlets.
The MCS dispenser within SICHARGE FLEX can provide up to 1,500 A, facilitating rapid charging cycles for heavy-duty electric vehicles, such as trucks and buses, as well as city and intercity buses. Siemens highlights the system's ability to accommodate installations where dispensers can be positioned up to 300 metres away from the central power cabinet, making it suitable for expansive fleets or logistics depots.
Installation options include floor mounting with a minimal footprint-0.1 m2 for CCS and 0.2 m2 for MCS-plus provisions for wall or overhead mounting, addressing space limitations commonly encountered at busy urban and transportation sites. The system also features a front-in, front-out cooling design, allowing for wall placements and further enhancing placement flexibility.
Management and integration
SICHARGE FLEX integrates into Siemens' existing eMobility ecosystems. A cloud-based management tool, Sifinity Control, provides operators with comprehensive visibility and remote control over the system, ensuring maximum uptime and optimised usage. Through this platform, operators can manage setup, tailor user interfaces, and monitor ongoing charging sessions across their infrastructure.
Depot operators also have the option to integrate with DepotFinity's smart energy management, which balances the energy requirements of large EV fleets against available grid capacity, helping to lower total cost of ownership by reducing the need for grid upgrades. Siemens has prioritised ease of installation and ongoing maintenance, with the product designed for longevity in commercial use.
Customer pilot and deployment
Before its general market launch, the SICHARGE FLEX system attracted the attention of several industry participants. One early adopter is OMV, a Charge Point Operator and Mobility Service Provider in Central Europe, with a network spanning Austria, the Czech Republic, Romania, Slovakia and Hungary.
OMV will install the first SICHARGE FLEX system at a transit hub in Kufstein, Austria, situated on the A12 corridor between Germany and Italy. Six charge points will be commissioned in the project's first phase, with future plans for expansion to ten points following an upgrade by the local Distribution System Operator. The hub will cater to passenger vehicles, electric trucks, and buses, enhancing the location's role in enabling alternative power options on established transport routes.
"At OMV, our mission is to provide our customers with reliable, high-performance charging infrastructure that meets the demands of modern mobility - today and tomorrow. The new site in Kufstein is a prime example of how we combine strategic location planning with cutting-edge technology to deliver real value: fast charging for eTrucks, eBuses and passenger cars, seamless user experience, and future-ready scalability," said Eric Schulze, Senior Vice President Retail Mobility & Convenience, OMV.
"As both a Charge Point Operator and Mobility Service Provider, we are proud to be the first to bring this system into operation and to continue leading the way in sustainable transport solutions across Central Europe."
Sustainability and cybersecurity
Siemens states that SICHARGE FLEX's design supports grid-balancing functionality, providing capabilities to enhance the stability of energy networks as demand for eMobility infrastructure increases. Cybersecurity also forms a core part of the system, incorporating "Security by Design" features such as encryption of data both at rest and in transit, along with secure boot processes to enhance resilience against cyber threats.
"The introduction of SICHARGE FLEX marks a significant milestone in our journey to build a comprehensive and sustainable E-Mobility ecosystem," said Markus Mildner, CEO eMobility, Siemens Smart Infrastructure.
"This solution embodies our vision for a future where EV charging is not only fast and reliable, but also seamlessly integrated and highly efficient. SICHARGE FLEX empowers our customers to confidently scale their operations, optimize energy use, and contribute to a cleaner, more electrified world."
SICHARGE FLEX is scheduled to become available for purchase in 2026, with Siemens eMobility intending to support deployments across a variety of sectors, including transport and logistics operators, charge point providers, and original equipment manufacturers.
