In 2015, we turned our product development attention towards designing a battery powered fleet that would respond to the mining industry’s growing need for cost containment through energy and mine design efficiencies, along with improving underground air quality for miners.

The MacLean EV Series product line gives our customers access to best-in-class technology, and then successfully integrates these components into mobile underground equipment by leveraging our multi-discipline engineering expertise, hard rock mining knowledge, and custom manufacturing experience. In other words, you can’t just understand the battery cycle, you need to understand the mining cycle in which it will be used.

In 2016, we sold our first battery electric vehicle unit and by the end of 2019, we had sold 31 battery electric vehicle units, across five separate model lines. To date, MacLean has sold and commissioned battery electric production support mining vehicles at nine mine sites across three Canadian provinces, amassing some 40,000+ operating hours.

MacLean is now taking its ‘EV-proven, EV-ready’ message to the mining world – for production support mining vehicles, considering the benefits of incremental battery electric vehicle introduction to allow for workforce training and supporting operator buy-in, which will pave the way for broader fleet electrification down the road.


Depth of BEV experience and expertise within utility vehicle and ground support equipment categories – global technology leadership
Ease of introduction from on-board charging design – no new electrical infrastructure required
Ability to lease batteries to address site-level questions around end-of-life battery management – financial flexibility

When we set out to electrify the MacLean product lines in 2015, we identified a number of key requirements that would guide our design process:

System must be adaptable to all MacLean mobile equipment (new and retrofit) and all mine requirements
System must be compatible with existing power supply/voltage, and not require additional underground electrical infrastructure
System must be flexible to enable incorporation of emerging technology
System must deliver equivalent or better performance than diesel power configuration
System must be scalable to as to provide the ability to deliver site and application-specific solutions
System must deliver high degree of commonality across MacLean suite of underground mining vehicles

Product development result = battery propulsion technology engineered for life underground, and customized to the application

The transition to full or partial EV fleets opens up a range of benefits to mining companies looking for ways to mitigate rising energy costs, improve air quality, and economically access deeper ore bodies:

Elimination of all diesel particulate matter (DPM) and all other emissions associated with diesel engines
Elimination of all air quality issues associated with dust generation and diesel exhaust porting
Elimination of engine noise, vibration and heat associated with diesel engines

Overall reduction of ventilation required to match diesel horse power ratings underground
Overall reduction of energy required to condition ventilation air
Overall reduction of parts per unit and resulting spare part stocking expense
Elimination of diesel engine servicing and scheduled maintenance
Elimination of diesel fuel costs – purchase, transportation to minesite, underground distribution, and surface storage

Elimination of potential ignition source generally associated with diesel exhaust systems and wrapping or shielding

Potential to reduce site-level GHG footprint
Contingency against electricity grid transmission stability (i.e. brown-outs when peak load exceeded)
Performance not impacted by altitude (battery propulsion does not require de-rating)
