Now, futuristic car that uses body as battery

London, Sep 28 (IANS) Manufacturers of hybrid and electric cars face a seemingly insurmountable problem — heavy batteries that add weight and bulk to vehicle design without boosting its efficiency. Now, Volvo is developing a prototype that uses its body to act as a rechargeable battery.
The futuristic car would be able to store braking energy while it is being driven and also store energy when it is plugged in overnight to recharge.

The three-year project to develop the car was launched earlier this year among Volvo, Imperial College in London and seven other European institutes, reports the Daily Mail.

Imperial College is working on a composite blend of carbon fibres and polymer resin that can store and charge more energy faster than conventional batteries.

The material is extremely strong and pliant, which means it can be shaped for use in building the car’s body panels.

Volvo claims that the car’s weight can be reduced by 15 percent if steel body panels are replaced with the new material.

Scientists are developing the composite material so it can store more energy and are studying ways of producing the material on an industrial scale. Only in the final stage of the project will the battery be fitted to a car.

“Our role is to contribute expertise on how this technology can be integrated in the future and to input ideas about the advantages and disadvantages in terms of cost and user-friendliness,” says Per-Ivar Sellergren, development engineer at the Volvo Cars Materials Centre.

Initially, the car’s spare wheel recess will be converted into a composite battery.

“This is a relatively large structure that is easy to replace. Not sufficiently large to power the entire car, but enough to switch the engine off and on when the car is at a standstill, for instance at traffic lights,” said Sellergren.

If the project is successful, there are many possible application areas.

Mobile phones could be as thin as credit cards and laptops will last far longer without needing to be recharged.
