A unique, multipurpose UGV (unmanned ground vehicle) will be the first
vehicle of its kind to use ultracapacitor technology. The high power
cells from record-breaking manufacturer Skeleton Technologies will be
used to deliver greatly increased energy efficiency and product
reliability. The hybrid UGV has been developed by Estonian defence
solutions provider Milrem, a company specialising in military
engineering, repair and maintenance.
Unlike existing UGVs it provides a universal platform for any
application from communication relay to medevac, lifting platform to
fire-fighting. This plug-and-play capability is made possible by housing
all equipment inside the vehicle’s tracks. The multipurpose UGV can be
used for a wide range of defence requirements including reconnaissance
and observer missions, targeting weapon systems and providing support
solutions such as medical supplies. The universal platform allows
operators to optimise their vehicle fleet and reduce life cycle
management costs with simplified maintenance and spare supplies. With
energy consumption becoming an increasing concern in the defence sector,
the Milrem UGV was designed to be as efficient as possible. A highly
sophisticated control unit regulates energy flow between the diesel
generator, electric motors and Skeleton Technologies’ ultracapacitors.
This system reduces overall energy consumption by 25–40%. The
ultracapacitors also ensure reliability by starting the vehicle in cold
conditions or after prolonged periods in storage. Kuldar Väärsi,
Chairman of the Board at Milrem, explains why they chose to work with
Skeleton Technologies: “Firstly we chose these ultracapacitors for their
performance; we knew they would deliver the efficiency and reliability
we required. But we also liked the company’s approach to working
alongside their customers to develop new products and new ideas.”
Ultracapacitors are a highly efficient form of energy storage that are
able to provide very high currents of power. Skeleton Technologies’
cells can also charge and discharge millions of times, offering
lifetimes up to 500 times longer than batteries. Crucially for
applications in colder climates, the technology can operate in
temperatures as low as -65 °C.
“We are proud to have worked with Milrem for our first deployment in the
defence sector,” explains Skeleton Technologies Chief Executive
Officer, Taavi Madiberk. “From powering space shuttles with the European
Space Agency to ensuring cold weather start in trucks, the range of
applications for our high-power technology is increasing all the time.”
The first prototype of the Milrem multipurpose UGV will be unveiled in
London at Europe’s leading defence and security event, DSEI 2015 which
runs from 15 to 18 September. Milrem can be found at stand N3-362.
