BMW is developing a very innovative technology for recharging electric vehicles. It will allow generating electricity on roads with potholes. The invention has already been registered with the German patent office, according to CarBuzz.

The patent describes a device that converts the kinetic energy of the suspension into electricity and charges the battery. Normally, the up and down movements of the suspension over bumps in the road are damped by the springs and dampers, and the energy is converted into heat and is essentially wasted.

Developed by BMW engineers, the setup involves a small flywheel in the car's suspension that spins a special generator that generates electricity. It is noteworthy that it can charge both the lithium-ion battery of an electric car, and a conventional 12-volt battery of a gasoline or diesel model.

The technology will not be cheap, so if it goes into production, it will first appear on more expensive electric vehicles a German brand, such as the new BMW i7.
