First-of-its-kind mobile megawatt charging solution brings high-power charging directly to heavy equipment, overcoming charging and grid-infrastructure constraints at remote worksites
FREMONT, CA., November 9, 2026: DIMAAG-AI, Inc. today announced the shipment to Komatsu of a 20-ton electric excavator powered by DIMAAG-developed electrification technology, together with DIMAAG’s Mobile Megawatt Charging System (MWCS). The system is designed to enable battery-electric heavy equipment to maintain full-workday utilization at remote jobsites.
Large battery-electric equipment typically requires extended charging periods, while remote jobsites may lack the high-power electrical infrastructure needed for fast charging. The result is lost operating time compared with diesel equipment. DIMAAG’s system is designed to overcome both constraints. DIMAAG integrated its Zenius high-power battery modules into Komatsu’s 20-ton-class electric excavator, enabling megawatt-scale ultra-fast charging while managing the thermal demands of repeated high-power charging and discharging. DIMAAG’s self-propelled, all-wheel-drive MWCS brings megawatt-scale charging directly to the machine. By replenishing substantial energy during short operational breaks, the system supports operation throughout the workday without requiring the excavator to travel to fixed charging infrastructure.
The second constraint is the site itself. Where only 30 to 100 kW of grid power is available, the MWCS accumulates energy at that level overnight, then delivers it at megawatt-scale power when heavy equipment needs to recharge during the workday. This decouples the charging power available to the machine from the instantaneous power capacity of the local grid, enabling ultra-fast charging even at worksites with limited electrical infrastructure.
DIMAAG invented, engineered and built the excavator’s ultra-fast charging battery technology, as well as the MWCS using its ENCORE (Electric No-Compromise Off-Road Ecosystem), integrating Zenius battery technology, power electronics and controls for heavy-duty electric operations. Together, these technologies enable high-power energy transfer between the MWCS and the machine while managing the electrical and thermal demands associated with repeated ultra-fast charging. The delivery advances the companies’ collaboration from the technology showcased at bauma 2025 to a complete electrification and mobile charging system designed for high-power electric off-road equipment.
“At bauma, we demonstrated a new approach to electrifying heavy equipment,” said Ian Wright, CTO of DIMAAG-AI and Tesla co-founder. “Now, we have built and delivered the complete system. For electric construction and mining equipment to replace diesel, it has to operate all day. Ultra-fast charging enables new possibilities for zero-emission heavy machinery.”
DIMAAG addresses the thermal and power-management challenges that come from moving this much energy in a short time with its Zenius battery system featuring Direct Dynamic Dielectric Cooling (D3C), engineered to manage the heat generated during repeated high-power charging and discharging. The MWCS allows for high-power charging to move with equipment across construction and mining sites.
“Through our collaboration with DIMAAG, we are launching new proof of concept (PoC) tests utilizing mobile ultra-fast charging technology. For electrification to become more widely adopted, challenges such as charging times and power supply infrastructure need to be addressed. Through these PoC tests, we will explore new possibilities for improving productivity while reducing environmental impact. We will continue to advance jobsite-wide energy management through co-creation with partners, including DIMAAG, with the aim of realizing next-generation on-site energy solutions that create new customer value.” said Taisuke Kusaba, Representative Director and Chief Technology Officer of Komatsu Ltd.
