The mining industry is accelerating its decarbonization efforts, with a key focus on reducing emissions from haul trucks - currently responsible for up to 50% of a mine’s energy use. To support this transition, CharIN, with collaboration from ICMM, have released a new Dynamic Charging Interface (DCI) White Paper, defining the technical requirements for a standardized, interoperable in-motion charging solution. The paper outlines how dynamic charging can enhance efficiency, minimize downtime, and support both diesel-electric (DEHTs) and battery-electric haul trucks (BEHTs) across surface and underground mining operations. By establishing common technical guidelines, it paves the way for greater industry-wide adoption of electric mining fleets.
The mining industry rapidly adopts low-emission technologies to reduce its carbon footprint and meet net-zero targets. A key challenge is the significant greenhouse gas emissions from diesel-powered haul trucks, which account for up to 50% of a mine’s total energy use and emit an estimated 68 million tons of CO₂ annually.
Electrifying haul fleets is a crucial step towards sustainable mining, but efficient and standardized charging solutions are essential to ensure safety, interoperability, and operational efficiency. The industry drives innovation by advancing zero-emission haul truck technology while reducing environmental impact.
CharIN Mining Project Aims To Achieve Interoperability
As the mining industry adopts electric solutions, there is a need for standardized charging networks, robust energy management systems, and integrated technologies to support these innovations. Therefore, CharIN has founded the Task Force Mining that has now been incorporated into CharIN's ongoing working groups as project. CharIN plays a key role in advancing this transition and ensuring interoperability, safety, and efficiency across charging networks and technologies used in the mining sector.
Approach to Interoperability
Interoperability is the ability and capacity of systems and products to function and interact with other systems and products via shared exchange of data, protocols, standards, and communications.
Elements of Interoperability
The project team co-created this diagram to illustrate a need for industry collaboration on key interface points to deliver interoperability.

As part of the ICMM-CharIN collaboration, significant progress has been made in the development of the Extreme Megawatt Charging System (X-MCS). Designed to push the limits of high-power charging, X-MCS aims to support the largest and most energy-intensive mining vehicles, ensuring rapid, efficient, and reliable charging in demanding environments. Building on the foundation of the Megawatt Charging System (MCS), this new solution introduces higher power capabilities, enhanced safety features, and greater adaptability to various mining applications. Additionally, automation and interoperability remain key priorities, ensuring seamless integration across the industry. The White Paper detailing X-MCS’s technical specifications and industry impact is currently in its final editorial stages and will be published soon.
The ICMM-CharIN collaboration continues to drive innovation in mining electrification. A key milestone is the development of the Ruggedized Megawatt Charging System (R-MCS), a specialized charging solution designed to withstand the harsh conditions of mining environments. Building on the Megawatt Charging System (MCS), the R-MCS enhances voltage capacity, durability, and chemical resistance, ensuring a robust, high-performance charging infrastructure for battery-electric heavy-duty vehicles. It also integrates automation technologies, enabling automated coupling for improved safety and efficiency. The White Paper outlines the technical specifications, communication protocols, and safety measures essential for global standardization. By addressing the unique challenges of mining operations, the R-MCS paves the way for a more sustainable, efficient, and electrified future in the industry.
