ABB E-mobility has introduced the OM X-Series, a distributed charging platform designed for high-duty-cycle and megawatt-scale EV charging applications. The system is aimed at large-scale use cases such as transit depots, logistics hubs, and highway charging corridors.
The OM X-Series is scalable from 800kW to over 10MW and can support more than 100 charging points. It replaces conventional isolated charging clusters with a coordinated, site-level architecture. The launch follows the company’s earlier A-Series high-power chargers (2024) and the OM M-Series system introduced in April 2026.
Built for continuous high-load operations, the platform features an end-to-end liquid-cooled power system, including power cabinets with integrated cooling units, liquid-cooled modules, and charging cables. According to the company, its silicon carbide modules deliver over 98% conversion efficiency, while built-in redundancy ensures uninterrupted operations even during disruptions.
The platform is based on a site-level DC bus architecture, allowing dynamic power distribution based on demand. It also supports direct integration of battery energy storage systems, improving efficiency by over five percentage points compared to AC-coupled systems, while enabling peak load management.
The initial configuration includes two 800kW cabinets connected via a DC bus, supporting up to 24 charging outputs. The system is designed to scale to multi-megawatt deployments without requiring significant infrastructure changes.
CEO Michael Halbherr stated that EV charging is evolving toward continuous, high-utilization scenarios where thermal stability and energy efficiency are critical not just for performance, but also for overall economics.
