New EV Charger Scales to 10 Megawatts Like a Power Plant

Electric vehicle charging is getting a major upgrade that could finally make fleet operators stop worrying about whether their stations can keep up.

ABB E-mobility just unveiled the OM X-Series, a charging system that can deliver up to 10 megawatts of power across more than 100 charging points simultaneously. Instead of adding chargers one by one as demand grows, the system works like a mini power plant that distributes electricity wherever it's needed in real time.

The technology targets the places where charging headaches hurt most: bus depots, delivery fleet hubs, and busy highway corridors. These locations need vehicles charged and back on the road quickly, often running nonstop throughout the day.

What makes this different is how it handles heat and efficiency. The entire system uses liquid cooling instead of air, running through the cabinets, power modules, and even the charging cables themselves. That design maintains over 98% energy efficiency during continuous operation, not just during short bursts.

The architecture includes a central DC bus that acts as the backbone, moving power where it's needed moment by moment. Battery storage connects directly to this same system, which ABB says improves efficiency by over 5% compared to older designs while helping sites avoid expensive demand charges during peak hours.

Here's the part that saves money long term: sites can start small and expand without tearing everything out and rebuilding. A location might begin with 1.6 megawatts supporting 24 charging points, then scale up to multi-megawatt capacity using the same foundation as demand increases.

The Ripple Effect

This shift matters beyond just faster charging. When fleet operators can rely on their charging infrastructure the way they rely on the electric grid, it removes one of the biggest barriers to going electric at scale.

Delivery companies, transit agencies, and trucking operations have hesitated to electrify entire fleets partly because they worry about whether charging systems can actually handle the constant, heavy use. A system designed from the ground up for sustained loads changes that calculation.

The technology also prepares sites for vehicle-to-grid capabilities, where electric vehicles can send power back to the grid during emergencies or peak demand times. As regulations evolve to support this, the infrastructure will already be in place.

Michael Halbherr, CEO of ABB E-mobility, captured the shift perfectly: at this scale, thermal stability and energy efficiency aren't just specifications anymore. They're the actual economics that determine whether large-scale electric fleets succeed or struggle.

The electric vehicle revolution just got infrastructure that can finally keep pace with ambition.
