TYRE that powers your electric car as you drive
World renowned Goodyear company has unveiled Concept BH03 tyre at the Geneva International Motor Showthat could spell the end of charging stations, and ultimately petrol cars, by charging the car as it drives. Called BH023, the tyre concept is fitted with thermo-piezoelectric materials.
The tyre has also been designed to be ‘ultra-black’ to absorb as much heat as possible. When being driven, the friction between the tyre and the road as well as the ‘squeezing’ and movement of the piezoelectric material as it rolls generates a small electric voltage. This electricity is captured and directed to the car’s battery to charge it as it moves. When parked, sunlight heats the tyre and this heat is transformed into electricity using the thermo-electric material.
This visionary tyre technology could eliminate the vehicle-range anxiety motorists may have with electric cars.
