Implementation of Battery Electric Vehicles in Surface Mining

As mining companies move toward fleet electrification, clear guidance is essential for those exploring or preparing to implement the addition of battery electric vehicles in their operations. 

Electrification of a surface fleet is a large investment, encompassing everything from the vehicles to infrastructure and charging solutions. Without strategies for this transition, investment decisions can be stalled, preventing companies from making informed decisions with their path forward.  

This guideline will aim to provide recommendations for those considering implementation of BEVs in surface mining. Successful implementation of BEVs is, for many mining companies, one of the critical enablers to reach greenhouse (GHG) reduction targets. Electrification can also reduce the total cost of operation by reducing the cost of fuel and equipment maintenance needed; however, this requires industry alignment on technical solutions to reduce cost by creating larger volume products.  

BEVs, including all vehicles ranging from haul trucks to light vehicles, in surface mining operations are one of the focuses of development, with small-scale commercial trials underway for ultra-class battery electric trucks. However, large scale deployment of BEVs faces notable constraints and operational readiness challenges due to: 

• Frequent changes in mine plans 
• Limitations in battery and charging technology 
• The need for sophisticated power management systems 
• Safety concerns related to expected voltage encounters in battery electric systems and large energy capacities 
• Lack of standardized maintenance practices 
• The need for upskilling/reskilling and ensuring workforce acceptance 
• The financial commitment
