Komatsu launches proof-of-concept tests of next-generation on-site energy solutions utilizing DIMAAG-AI’s megawatt-level ultra-fast charging system

November 10, 2026

Komatsu Ltd. (President and CEO: Takuya Imayoshi) will launch proof-of-concept (PoC) tests combining a 20-ton-class electric excavator modified to support ultra-fast charging and a megawatt-level ultra-fast charging system developed by DIMAAG-AI, Inc. (headquartered in California, U.S.; CEO: Satish Padmanabhan; hereafter “DIMAAG”), a developer of ultra-fast charging technologies and electrification solutions. Through these PoC tests, Komatsu will evaluate the potential to significantly reduce charging times for electric construction equipment and the feasibility of developing next-generation on-site energy solutions that supply energy to a wide range of mobile and fixed equipment.

At construction and mining jobsites, the electrification of construction equipment is attracting growing attention as customers seek to achieve both reduced environmental impact and improved productivity. However, for electric construction equipment to become more widely adopted, charging time remains one of the challenges facing customers, as it affects machine operating hours and overall jobsite productivity.
In these PoC tests, Komatsu aims to significantly shorten charging times for the 20-ton-class electric excavator by utilizing DIMAAG’s megawatt-level ultra-fast charging technology, thereby increasing the utilization of electric construction equipment and contributing to both reduced environmental impact and improved productivity.
DIMAAG’s mobile megawatt charging system is self-propelled and equipped with all-wheel drive, enabling it to travel close to equipment requiring charging and supply energy on site. Unlike stationary charging infrastructure designed for specific equipment models, Komatsu aims to supply energy to a wide range of fixed and mobile equipment used at jobsites, including construction, mining and forestry equipment.
Looking ahead, Komatsu aims to optimize energy use across the entire jobsite by enabling customers to flexibly supply and distribute energy according to jobsite conditions, the composition of their mobile and fixed equipment, and operating status. This will help create jobsite environments in which customers can advance electrification more flexibly, going beyond the electrification of individual construction equipment.

Through these PoC tests, Komatsu will verify the performance of ultra-fast charging and its operability under actual jobsite conditions, while also assessing the feasibility of energy management across entire jobsites, including mobile equipment, fixed equipment and vehicles. Komatsu will continue working with customers to create solutions that both reduce environmental impact and improve productivity at construction and mining jobsites.

Taisuke Kusaba, Representative Director and Senior Executive Officer, CTO, Komatsu Ltd.
“Through our collaboration with DIMAAG, we are launching new 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.”

Ian Wright, CTO, DIMAAG
“At bauma 2025, we presented a new approach to the electrification of construction machinery in collaboration with Komatsu. We are honored to now demonstrate this concept by combining actual machinery with DIMAAG’s ultra-fast mobile megawatt charging system. For electric construction and mining equipment to serve as a viable alternative to diesel-powered machines, it is crucial to minimize charging-related downtime and maintain high productivity throughout the day. By combining DIMAAG’s ultra-fast mobile megawatt charging technology with Komatsu’s expertise in construction machinery, we aim to further expand the potential of electric construction equipment and accelerate the electrification of jobsites.”
