Siemens has officially launched its latest electric vehicle charging solution, the SICHARGE FLEX, targeting the rising global demand for high-power, flexible charging infrastructure. The unveiling took place at Busworld 2025, and the company says the system is especially designed for fleet depots, logistics hubs, and public transport networks that serve both passenger cars and heavy commercial EVs.
The new charger delivers DC output ranging from 480 kW to 1.68 MW, enabling it to serve a broad spectrum of vehicles—from standard EVs to heavy buses and trucks. A smart energy distribution module dynamically allocates available power among multiple charging outlets in real time, which Siemens says helps maximize throughput and charging efficiency for fleets of various sizes.
A key feature of SICHARGE FLEX is its modular, scalable architecture. Up to four Megawatt Charging System (MCS) dispensers can be paired with a central power cabinet, and these dispensers can be placed at distances of up to 300 meters from the main unit. The design is compact—just 0.1 m² for CCS dispensers and 0.2 m² for MCS—allowing deployment even in tight urban or depot environments.
Siemens already has a real-world deployment underway in Kufstein, Austria, along a strategic transnational corridor between Germany and Italy. The site will initially host six fast-charging ports serving cars, buses, and trucks, with plans to expand to ten outlets following upgrades to the local grid. This deployment is aimed at demonstrating the feasibility of megawatt-scale charging under operational conditions.
Integration with Siemens’ Sifinity Control cloud platform allows remote monitoring, predictive maintenance, and operational optimization of the charging infrastructure. The connectivity gives operators detailed oversight and control, which Siemens claims can improve system uptime and reliability.
With SICHARGE FLEX, Siemens aims to set a new benchmark in EV infrastructure. By uniting technical innovation, flexibility, and modular scalability, the system addresses key bottlenecks such as charging speed, space constraints, and infrastructure utilization. Siemens positions this launch as reinforcing its leadership in smart mobility and its commitment to accelerating the transition to sustainable transport.
