In metropolitan traffic conditions, vehicles are often made to accelerate and decelerate frequently, at times, within very close intervals. During the braking phase, much of the initial kinetic energy of the vehicle is dissipated to the environment as heat, sound, or other forms of ambient energy, creating a low-efficiency system. This project investigates the applications of piezoelectric principles in harnessing useful energy through regenerative braking. Specifically, this project investigates the applications of the piezoelectric effect in converting the forces that brakes exert on the rotors/wheels of electric and hybrid vehicles into useful electrical energy, which can later be stored or used to power load(s). Although electromagnetic induction-based regenerative braking systems are currently being employed, the efficiency value of such systems lies in the range of 40 - 55%. This project investigates the enhancement of the efficiency of regenerative braking systems as a whole, in order to increase the driving range(s) and fuel efficiency of electric and hybrid vehicles. This project makes use of common piezoelectric disks in order to conduct experiments, particular his project investigates the conversion of the energy which is typically lost during vehicular braking to useful electrical energy through the applications of the principles of the piezoelectric effect.
