ABB's New DC Fast Charger Goes Into Megawatt Territory

Why It Matters

Megawatt‑class chargers are essential for supporting next‑generation EVs and heavy‑duty trucks, and ABB’s modular approach reduces capital risk while expanding high‑power infrastructure.

Key Takeaways

• ABB's OM M-Series delivers up to 1.2 MW to a single EV
• Power density reaches 625 kW per square meter, maximizing space
• System scales from 200 kW to 1.2 MW via modular cabinets
• Single MCS connector supports heavy‑duty trucks at 1.5 kA
• ABB competes with Tesla, Alpitronic, BYD in megawatt charging race

Pulse Analysis

ABB’s OM M‑Series marks a decisive step toward truly ultra‑fast charging. By packing 1.2 MW of power into a cabinet that occupies less than two square metres, the company delivers a power density of 625 kW per square metre—far above conventional chargers. The modular architecture lets operators start with a 200 kW unit and add cabinets as utilization climbs, preserving capital efficiency while future‑proofing sites. Coupled with ABB’s OM Ultra dispenser, the system can charge a single vehicle at 1.5 kA, a capability crucial for heavy‑duty trucks and high‑capacity fleet depots.

The market pressure for megawatt chargers is intensifying as EVs routinely accept 300 kW and above. Automakers are rolling out models with 350‑kW and 400‑kW charging windows, while electric trucks demand even higher rates to stay competitive with diesel. ABB’s offering positions it alongside Tesla’s 1.2 MW V4 Superchargers, Alpitronic’s 600 kW split‑DC units, and BYD’s 1.5 MW Flash chargers. By providing both single‑vehicle megawatt output and the ability to serve up to 24 cars simultaneously, ABB addresses a broad spectrum of use cases—from highway rest‑stop corridors to urban depot hubs.

For site developers, the OM M‑Series reduces the footprint and wiring complexity traditionally associated with high‑power installations. The cabinet’s liquid‑cooled MCS connector handles the thermal load of megawatt charging, while the optional CCS/NACS adapters keep the system compatible with the majority of North American and European fleets. As utilities grapple with the grid impact of concentrated megawatt loads, ABB’s modular scaling allows incremental grid upgrades, smoothing demand spikes. In the United States, where fast‑charging plug installations surged past 3,000 in Q1 2026, the OM M‑Series could accelerate deployment of highway‑grade chargers, supporting the next wave of EV adoption and reinforcing ABB’s foothold in the global charging ecosystem.
