STEV is the next generation in fully electric mining vehicles

STEV is the next generation in fully electric mining trucks




STEV (subterranean electric vehicle) is an innovative fully electric
automobile and the next generation in mining vehicles, specifically designed
for the harsh environment and rigorous duty cycle required to operate in
underground environments. it features an industry first hybrid charging
system which allows for both off-board DC fast charging and on-board AC
opportunity charging. in addition, the vehicle also features a dynamic
braking system that prevents unwanted accelerations and maximizes range by
converting excess kinetic energy in to electrical energy. STEV reduces an
organization’s carbon footprint, maximizes energy efficiency and minimizes
operating costs.

STEV provides consistent, intuitive and transparent operational feedback and
a tuned suspension to create a more pleasurable driving experience. miners
can develop respiratory-related disease or death due to exposure to diesel
emissions in underground mines. to mitigate such danger mechanical
ventilation must be provided, constituting a large portion of a mine’s
operating budget. in response STEV offers health, environmental, and
reliability benefits and makes positive financial sense.

miller technology developed STEV over a 2.5-year period to meet the evolving
needs of global mining operations while recognizing the need to match or
surpass the performance of traditional diesel equipment. high strength alloy
steel construction maximizes safety in roll over and falling objects
situations and minimizes overall weight. the vehicle is also equipped with a
powerful mid-ship mounted motor with dual output flanges resulting in
impressive full time 4-wheel drive.

miller’s system vastly reduces the number of moving parts, maintenance
costs, and downtime. battery modules used in the energy storage system have
passed rigorous highway and marine testing standards to ensure the utmost
safety. our modular arrangement makes it possible to adapt the platform to
various usage cases. all major systems are equipped with a liquid loop that
is primarily utilized for cooling but can be adapted to allow for heating in
extremely low temperature environments.

its hybrid charging system allows both off-board CCS type 2 DC fast charging
and optional on-board charging for opportunities anywhere in a mine. range
is enhanced and maintenance costs reduced through an innovative dynamic
braking system preventing unwanted acceleration and by converting excess
kinetic energy in to electrical energy. STEV is easily configured in two or
four door variants for transportation of personnel or various work truck
builds such as a flat deck or scissor lift.

STEV is quiet so a forward projected white noise pulse is used while driving
to warn pedestrians. the cockpit is designed with touch screen interface
capability with display units providing operating feedback in several ways.
miller is respected industry wide as an innovative and resourceful designer
and fabricator of cutting edge technologies and equipment. solutions
developed by miller have positive and direct, real world, impacts for
operators in the field. through the development of equipment such as STEV,
miller is harnessing efficiencies to enhance the bottom line for operators,
deliver environmentally friendly options for mining and tunnelling
industries and maximize equipment value/investment for the end user.
