The MWCS, which was highlighted by Komatsu at the recent bauma construction and mining equipment expo in Germany, enables charging at point of use, thereby significantly reducing downtime associated with trips to fixed charging stations.
The Dimaag's MWCS system features 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 1MW to 6MW. The mobile MWCS also 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. Dimaag's electrification and high-power megawatt charging systems are designed to achieve this.”
Taisuke Kusaba, senior executive officer (Jomu), CTO, supervising research & development at Komatsu, commented: "Despite the challenges in developing the market for electric construction equipment, primarily due to installation costs and the need for adequate power supply infrastructure, we remain committed to accelerating our efforts toward market development through collaboration with companies such as Dimaag, in pursuit of our challenge goal to achieve carbon neutrality by 2050.”
