Komatsu, Dimaag Bring Megawatt Charging to Sites

May 30, 2025
MWCS is scalable, offering capacities from 1 to 6 megawatts.

Komatsu has partnered with Dimaag to bring a mobile megawatt charging system (MWCS) to construction job sites for powering electric equipment at point of use.

Read today’s top news.

The MWCS has a compact, high-efficiency DC-DC converter and a long-life, high-discharge-rate Energy Storage System (ESS). Both components utilize an advanced thermal management system to optimize life cycle and safety during high-power delivery. The modular DC-DC converter is scalable, offering charging capacities from 1 megawatt to 6 megawatts. The mobile unit comes with 4-wheel drive and 4-wheel steering capability to navigate around tight surroundings and rough terrains.

“Dimaag is excited to collaborate with Komatsu, introducing our advanced ESS and DC-DC architecture to revolutionize electrification in construction,” stated Ian Wright, VP Engineering at Dimaag and Tesla co-founder.

“Off-road vehicle electrification demands practical solutions that not only meet but exceed the performance of equivalent large diesel engine vehicles, while also providing substantial Total Cost of Ownership (TCO) savings,” said Ian Wright, VP engineering at Dimaag. “Dimaag’s electrification and high-power megawatt charging systems are designed to achieve this.”
