Goodyear concept tyre can charge EV batteries

The BH-O3, shown at the Geneva Motor Show, features an ultra-black tread which can absorb energy heat and sunlight, while the thermoelectric material beneath transforms it into electricity which can be channelled into the battery.

Its sidewalls are self-supporting, which means they can be driven on with no pressure in the tyre, and the structure contains a piezoelectric material which transforms the structural deformation of the rubber while the car is rolling into electrical energy.

The BH-O3 is also designed to minimise rolling resistance, further increasing the range and efficiency of whatever it is fitted to.

Joe Zekoski, Goodyear's senior vice president and chief technical officer, said: "We envision a future in which our products become more integrated with the vehicle and the consumer, more environmentally friendly and more versatile."
