Komatsu, the century-old global heavy equipment manufacturer, has introduced a powerful new mobile charging solution developed with its partner Dimaag. The Mobile Megawatt Charging System is a high-capacity, mobile power unit designed to deliver fast charging directly at construction and off-road sites, reducing downtime and eliminating the need for distant charging stations.
The system was engineered by Ian Wright, a Tesla co-founder and now Vice President of Engineering at both Dimaag and Komatsu. It features a compact, high-efficiency DC-DC converter and a 295 kWh energy storage unit built for high-discharge rates and extended lifespan. Both parts include advanced thermal management systems for safety and performance during high-power use.
The modular converter allows for flexible power delivery, with outputs ranging from 1 MW to 6 MW, and includes an MCS connector for compatibility. This makes the system highly scalable and adaptable to a variety of heavy-duty charging needs.
Built to perform in rugged environments, the system includes four-wheel drive and four-wheel steering to navigate tight or uneven terrain. It measures 67 inches long, 59 inches wide, and 55 inches high, and can weigh up to 6.6 tons depending on configuration. Its 208 kW motor delivers continuous torque of 1,608 lb-ft (2,180 Nm) per wheel, a top speed of 22 mph (35 km/h), and can climb grades up to 40%. Spring-applied parking brakes add extra safety on slopes.
This launch marks a major innovation in mobile electrification for off-road applications, signaling Komatsu and Dimaag’s commitment to cleaner, more efficient heavy machinery operations.
