Transforming EV Charging with Megawatt Technology

Kempower and Windrose have successfully showcased their groundbreaking Megawatt Charging System (MCS) at EV Realty’s San Bernardino hub in California. This real-world test, which took place on March 25, 2026, marks a pivotal moment in the transition of MCS technology from Europe to North America, setting the stage for enhanced charging capabilities for heavy-duty electric vehicles.

The installation features a robust 1,200 kW Kempower Power Unit linked to two Mega Satellite dispensers, capable of delivering up to 1.2 MW and a continuous output of 1,500 amperes. This innovative infrastructure is designed to accommodate the anticipated influx of MCS-compatible heavy-duty trucks expected later in 2026, aligning perfectly with the upcoming commercial deployment.

Innovative Design and Thermal Management

Kempower’s MCS relies on cutting-edge liquid-cooled cable technology, a crucial component that ensures sustained performance at megawatt charging levels. With the ability to maintain 1,500 amperes of continuous output, effective thermal management is essential, as it mitigates cable degradation during extended charging sessions.

This modular design allows for up to seven satellite dispensers to connect to a single power unit, offering flexibility for operators. Even when MCS-capable trucks are not available, the system can function as a high-power charger, maximizing asset utilization. This versatility addresses a significant concern for charging hub operators, preventing stranded capital as the market transitions to MCS technology.

Real-World Testing and Fleet Integration

The successful test in San Bernardino marks the first real-world validation of MCS interoperability in North America. Unlike controlled laboratory settings, this demonstration proves that the system operates reliably with actual heavy-duty electric vehicles and integrates seamlessly with existing grid infrastructure.

EV Realty’s hub is strategically positioned to serve any MCS-compatible truck, enabling the operator to attract a wide range of manufacturers. Windrose’s involvement signifies that at least one OEM is prepared to launch MCS-capable vehicles, indicating a readiness within the industry for this advanced charging infrastructure.

Insights from European Deployment Experience

Kempower’s prior six months of MCS testing in Europe have laid a solid foundation for this North American launch. By partnering with truck manufacturers and charging operators, Kempower has garnered invaluable insights that reduce technical risks associated with scaling.

This transition from European pilots to North American deployment indicates that MCS technology has matured beyond proof-of-concept. It empowers operators like EV Realty to make informed capital investments, confident in the long-term viability and operational efficiency of this innovative charging solution.
