ABB E-mobility has introduced its OM X-Series charging platform at the ACT Expo in Las Vegas, expanding its portfolio of high-power charging systems for fleet operators and charging network providers.
The OM X-Series is designed to support charging sites with power outputs ranging from 800 kilowatts to 10 megawatts and can handle more than 100 charging points, according to ABB E-mobility.

The system follows a split-system architecture similar to the company’s recently launched OM M-Series. Centralised Power Cabinets distribute energy to connected charging dispensers across a site.
While the OM M-Series supports between 200 kW and 1.2 MW with up to 24 charging points, the larger X-Series is aimed at higher-capacity applications such as transit depots, logistics hubs and public fast-charging corridors.
ABB E-mobility said the system was engineered for sustained high-power usage, including megawatt-scale operations and mixed charging demands within shared energy infrastructure.

“Charging is moving toward mission profiles where systems must operate under sustained load for years, not just peak moments,” Michael Halbherr, CEO of ABB E-mobility, said in a statement.
“At that level of utilisation, thermal stability and energy efficiency are not specifications; they are the economics,” Halbherr added. “The X-Series is built for that standard from the architecture up.”
The X-Series uses a fully liquid-cooled power pathway designed to maintain performance and reliability during continuous high-load operation. The system includes liquid-cooled power modules, cooling-integrated Power Cabinets and liquid-cooled charging cables.

According to ABB E-mobility, the charging modules deliver conversion efficiency above 98% during continuous operation, which the company said provides advantages over air-cooled charging systems under heavy-duty operating conditions.
The OM X-Series is compatible with the same dispenser lineup used by the OM M-Series, including Solo, Duo, Dock and Ultra dispensers.
The dispensers support multiple charging standards, including CCS1, CCS2, North American Charging Standard and the Megawatt Charging System standard for electric trucks.

ABB E-mobility said compatibility between the two charging platforms allows customers to begin with smaller installations using the OM M-Series and later scale up to X-Series infrastructure as charging demand increases.
