new OM X-SeriesImage: ABB E-mobilityThe new OM X-Series from ABB E-Mobility shares a similar structure to the recently introduced OM M-Series. Like its predecessor, it consists of centralised technology cabinets called Power Cabinets, which can be connected to various dispensers. This design follows a satellite or split-system architecture.However, the X-Series is designed on a much larger scale than the M-Series. While the smaller M-Series offers a power output of 200 kW to 1.2 MW and supports up to 24 charge points, the X-Series scales from 800 kW to 10 MW and supports over 100 charge points.ABB E-Mobility states that the X-Series was developed for sites with the highest power demands, such as transit depots, logistics centres, and public fast-charging corridors. It is engineered for continuous high utilisation, megawatt-scale site-level power, and diverse operational profiles within a shared energy system.“Charging is moving toward mission profiles where systems must operate under sustained load for years, not just peak moments,” said Michael Halbherr, Chief Executive Officer of ABB E-mobility. “At that level of utilisation, thermal stability and energy efficiency are not specifications; they are the economics. The X-Series is built for that standard from the architecture up.”Thermal management is critical for this operational profile, as it ensures efficiency and reliability throughout the system’s lifespan. The X-Series achieves this through a fully liquid-cooled power pathway, which includes a Power Cabinet with integrated cooling, specially developed liquid-cooled power modules, and liquid-cooled charging cables. These features ensure comprehensive thermal management at all levels. The modules achieve a conversion efficiency of over 98% in continuous operation, not just as a peak value. According to ABB, this significantly outperforms air-cooled systems in relevant load profiles.The X-Series uses the same dispenser portfolio as the M-Series, including the Solo, Duo, Dock, and Ultra dispensers. These are available with charging connectors such as CCS1, CCS2, NACS, and MCS, including the new megawatt charging standard for electric trucks. The compatibility of these dispensers with both charging system series allows customers to start with the smaller M-Series and later expand to the X-Series infrastructure.Source: via email, abb.com
