Battery and electric vehicles in mining: design and power notes for engineers
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
Electrification of mining fleets is advancing beyond early pilots, with battery-electric haul trucks, loaders and light vehicles moving from trial phases into multi-year deployment contracts despite recent pull-backs in some OEM roadmaps. Dan Gleeson details how mines are pairing 6–8 MWh battery trucks with on-site fast-charging bays and trolley-assist lines, and integrating underground BEVs with upgraded 11 kV substations and ventilation recalculations. Operators are reassessing mine plans, ramp gradients and power quality to manage peak loads, charger placement and heat rejection from high-capacity battery systems.
Technical Brief
- OEMs are revising BEV fire-suppression layouts to protect battery enclosures and roof-mounted packs.
- Several mines are mandating intrinsically safe high-voltage connectors and interlocks on all fast-charge bays.
- Operators are updating traffic management plans to segregate BEV charge zones from diesel fuelling areas.
- Thermal runaway risk is being addressed with additional temperature sensors and battery health monitoring in underground fleets.
- Emergency response plans now include specific BEV isolation, venting and re-ignition protocols for battery fires.
- Ventilation and heat-stress procedures are being revised to account for altered heat sources and reduced diesel particulates.
- For future projects, regulators are starting to require BEV-specific risk assessments alongside conventional mine safety cases.
Our Take
International Mining also features in coverage of Boliden’s “green fleets” roll-out across European copper, nickel and zinc operations (Dec 2025), signalling that battery and EV themes are increasingly tied to concrete fleet decarbonisation case studies rather than just concept pieces.
With 2351 tag-matched pieces under Projects, Sustainability and Safety, battery and EV deployments in mines now sit alongside a large body of operational safety content, suggesting that traction power electrification is being treated as a core risk-management topic rather than a niche innovation.
International Mining’s role in the World Mining Congress 2026 item indicates that battery and EV fleet adoption is likely to be a front-of-agenda discussion for senior executives, shaping how new projects are benchmarked on carbon and occupational exposure standards over the next project cycle.
