Volvo is developing a material that allows car body panels to act as batteries
29 September 2010

Volvo has revealed that it is working on a feasibility study into creating car body panels that can also act as batteries.

The company is part of a consortium developing a material that can store and discharge electrical energy, but is strong, lightweight and pliant enough to be used for car parts.

The material is a plastic composed of carbonfibres and polymer resin. It can cut weight in vehicles by reducing the need for separate battery packs and by replacing the heavier steel currently used in car construction.

The technology has been patented by Imperial College London and the university has established a consortium of nine European companies – of which Volvo is the only car manufacturer – to continue its development.

Volvo: 'Think beyond CO2'

Dr Emile Greenhalgh, the project co-ordinator who works in Imperial College London’s Department of Aeronautics, said: “We are really excited about the potential of this new technology.

“We think the car of the future could be drawing power from its roof, its bonnet or even the door... Even the sat-nav could be powered by its own casing.”

The material could potentially be used for the casings of other electrical items, such as mobile phones and computers. This would similarly allow them to become more lightweight as there would be no need for a separate battery.

The European Union has given 3.5 million euros (£2.97m) of financial support to the project.

This seems to me to be an excellent idea. The cost would need to be low though - what happens when you have crash and the panels need replacing? If they are 10 x the price of a normal panel I can only impagine what will happen to the insurance premiums

The time has come to experiment with different materials to create a car's shape a keep down its eight, preferably. But will the conservative driver buy radical technology?

Seems a bit Tomorrows World, but amazing if it comes off

Great idea if it can be done viably.

Can's see power companies being ovely pleased with self powering tv's/computers or anything else. Maybe its them who make up the other companies devleloping it?
