When a threat from incoming fire is detected by the vehicle, the energy stored in the supercapacitor can be rapidly dumped onto the metal plating on the outside of the vehicle, producing a strong electromagnetic field.
Scientists behind the project claim this would produce a momentary "force field" capable of repelling the incoming rounds and projectiles.
Although it would last for only a fraction of a second, if timed correctly it could prevent rocket propelled grenades, which detonate on impact, from reaching their target. The supercapacitor could then be rapidly recharged ready for another attack.
