What Happened ABB E-mobility has launched the OM X-Series, a distributed DC fast-charging system built for transit depots, logistics hubs, and charging corridors. The system starts at 800 kW with one cabinet and 12 ports, and scales up to 10 MW supporting over 100 dispensers.
Context Fleet electrification — buses, trucks, logistics vehicles — creates a fundamentally different charging challenge compared to passenger EV infrastructure. Depot operators need systems that run at sustained high loads across many vehicles simultaneously, often around the clock. Most existing charging architectures weren’t designed for that kind of utilisation, and scaling them up typically involves significant civil works, stranded assets, or both. The shift to distributed, modular charging architectures is a direct response to these operational realities.
Why It Matters The OM X-Series separates AC/DC and DC/DC conversion so sites can scale toward multi-megawatt operation without rebuilding ground infrastructure. Starting at 800 kW and growing to 10 MW on the same architecture means operators aren’t locked into a fixed capacity ceiling from day one. It also shares its dispenser lineup with ABB’s OM M-Series, providing a clear upgrade path for sites already in that ecosystem.
Our Take High-utilisation charging sites need systems that run hard, stay cool, and scale without expensive civil intervention. ABB has built the OM X-Series around exactly those operational realities. For fleet operators and depot planners making infrastructure commitments today, this architecture makes the long-term economics considerably easier to justify.
