ABB E-mobility launches electric truck power management tech

The M-Series includes four models with power configurations that scale from 200 kW to 1.2 MW:

• M200: up to 200 kW (one cabinet)
• M400: up to 200 kW (one cabinet)
• M800: up to 800 kW (two 400-kW cabinets)
• M1200: up to 1.2 MW (three 400-kW cabinets)

For reference, the vocational Kenworth T880E has a 350 kW peak charge rate and can charge overnight for significantly less power. The 400-kW cabinet from the M-Series handles the fastest charging needs of Class 8 electric trucks—or many trucks’ overnight charging needs—making it a good size for small-scale fleet electrification without a large upfront capital investment.

The system is air-cooled and occupies a relatively small footprint. ABB E-mobility claims the M-Series has a power density of 625 kW per square meter. The M-Series dynamically distributes its power capacity across up to 24 charge points based on real-time demand.

The OM X-Series: Megawatt-scale fleet charging

The X-Series is meant for the full-scale charging depot: fleets with an extensive electric fleet, smaller electric fleets with fast charging needs, or public depots in areas with high demand. The X-Series is comprised of 800-kW cabinet units, which can scale from 800 kW to 10 MW and beyond and can handle more than 100 charge points.

The X-Series cabinets use liquid cooling and continuously achieve 98% AC-DC conversion efficiency. ABB also claims that, because the architecture decouples AC/DC and DC/DC conversion and is specified for future power levels, a site commissioned with a 1,600 kW setup (two 800-kW cabinets) can continue to scale on the same infrastructure.

As of now, the X-Series only offers two configurations:

• X800: up to 800 kW (one cabinet)
• X1600: up to 1600 kW (two 800-kW cabinets)

However, the company plans to extend the X-Series system to a multi-megawatt scale in the future.
