BAE Systems developed the patented technology to lighten the load of soldiers carrying rucksacks, which can weigh up to 76kg and be filled with numerous electrical items. The structural batteries store the electrical energy within the physical structure of a device thus helping to reduce or eliminate the need for traditional batteries, which create weight and bulk, as well as the burden and cost of carrying spares.
The potential scope for this technology is limitless, while the benefits for the defence sector have already been demonstrated in a high tech micro unmanned air vehicle, as well as a rudimentary torch.
To demonstrate the technology's application beyond the battlefield, BAE Systems have also applied the technology through a partnership with leading race car manufacturer Lola. The Lola-Drayson B12/69EV, zero emission 850 horsepower Le Mans Prototype car will incorporate structural batteries to power some of the on-board electronic systems. Upon completion, the Lola-Drayson B12/69EV aims to become the world's fastest electric racing car.
Alex Parfitt, Capability Technology Leader for Materials at BAE Systems said: "Structural batteries can be used in virtually anything that requires electricity from small gadgets to entire vehicles. It can not only support our soldiers on the frontline, but also revolutionise technology in the consumer market by allowing more efficient, elegant and lighter designs."
To develop this technology, scientists at BAE Systems merged battery chemistries into composite materials that can be moulded into complex 3D shapes and so form the structure of the device itself. It can then be plugged in when it needs recharging or utilise renewable power sources, such as solar energy.
The process makes use of nickel-based battery chemistries, which are commonly used in defence technology and future developments will allow integration of Li-ion and Li-Polymer chemistries found in consumer electronic products such as mobile phones, MP3 players, laptops, tablets and portable games. This will not only lead to improved product designs, but eliminating the need to buy batteries will reduce the lifetime cost to the consumer, as well as having environmental benefits.
Current development has demonstrated the ability to store useful energy in composites such as carbon fibre and glass reinforced plastic, but in the future it could also be incorporated into fabric for a wide range of lightweight applications, from tents with their own power supply to making electric blankets a literal reality.
For more attend Electric Vehicles Land Sea Air USA 2012 ,where uniquely we reflect the new realities that there are now six key enabling technologies and they are competing in all forms of EV, hybrid, pure electric and land, water and airborne, manned and unmanned. Speakers from ten countries detail the situation in their parts of the world including SYNPER 3 from Singapore, first to fly an electric helicopter recently, showing how up to 35% of helicopter crashes could be avoided with hybrid electric technology. Sun Yat-Sen University China and Germany Trade & Invest detail their national situations. Next generation batteries are covered by Robert Bosch (Bosch Group) of Germany, Oxis Energy UK, IBM USA and others. OLEV Technologies will show how to continuously pick up power, Schneider Electric of France how modern charging infrastructure is a system not boxes. There will be two presentations on supercapacitor breakthroughs - here is the future. See the full picture, with best-in-class speakers from across the whole world - Slovenia to Gibraltar, China to Canada, each carefully chosen by IDTechEx because of their leadership. There are two presentations on agricultural EVs and five on electric aircraft including Boeing and Airbus involvement. Other presenters include BMW (cars etc), Mitsubishi Motors (small commercial vehicles and cars), Daimler AG (commercial and military vehicles and cars) and Toyota (leader in electric forklifts, electric cars and buses but also presenting on its fuel cell vehicle program.) Uniquely, a large number of electric vehicle manufacturers not seen in conventional EV events will present including iRobot Corporation Autonomous Underwater Vehicles AUVs (better known for EVs as robot vacuum cleaners). Mission Motors and two others focus on electric motor cycles. Many manufacturers of industrial, commercial, military, cars and other EVs will be there. Come to this event where you avoid the usual speakers with nothing new to say and meet people new and useful to you without doing a lot of travelling to find them. Apply for an award.
