ABB E-mobility Unveils OM X-series Megawatt Charging Platform for Heavy-duty Applications

ABB E-mobility has introduced the OM X-Series, a distributed charging platform aimed at high-duty-cycle and megawatt-scale charging applications such as transit depots, logistics hubs and highway charging corridors.

The new system is designed to scale from 800kW to more than 10MW across over 100 charging points, replacing isolated charging clusters with a coordinated site-level architecture. The launch follows the company’s A-Series high-power chargers introduced in 2024 and the OM M-Series split charging system launched in April 2026.

According to ABB E-mobility, the X-Series has been developed for applications where chargers operate under sustained load conditions for extended periods. The system incorporates an end-to-end liquid-cooled power path, including a power cabinet with an integrated cooling unit, liquid-cooled power modules and liquid-cooled charging cables.

The company said the liquid-cooled silicon carbide modules deliver conversion efficiency of more than 98 percent under continuous operating conditions. The architecture also includes built-in redundancy intended to maintain operational continuity during planned or unplanned interruptions.

The charging platform is based around a site-level DC bus architecture that allows cabinets and storage assets to share power dynamically depending on demand. Battery energy storage can be connected directly to the DC bus, which ABB says improves round-trip efficiency by more than five percentage points compared to AC-coupled systems while also supporting peak shaving and demand management functions.

The initial configuration of the X-Series comprises two 800kW cabinets connected through a DC bus and supports up to 24 charging outputs. ABB E-mobility said the platform has been designed to scale to multi-megawatt deployments without requiring major civil rework.

The company also stated that the OM M-Series and X-Series use a common dispenser portfolio, allowing operators to expand from M-Series installations to X-Series configurations as charging demand increases.

“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 utilization, thermal stability and energy efficiency are not specifications; they are the economics.”
