Eco-friendly Vibration Energy Harnessing in Conventional Two-wheeler and Electric Vehicle

Naga Sudha Rani Behara and Prof. Putti Srinivasa Rao


Energy can neither be created nor destroyed but transforms from one form to another form. Energy harnessing is the process where the control and make use of natural ways such as load applied, free vibrations are analysed, captured and transformed to get low amount of voltage. The main aim of energy harnessing is to use eco-friendly vibrations to charge low electronic devices where there is no other way of available power sources like in remote locations and undersea applications. Specifically, the energy harnessing used in rechargeable dead batteries and improves by boost converter and to power low electronic devices, for charging mobiles. Piezoelectric materials are specifically chosen because of its dual nature of converting mechanical strain energy captured by vibrations into electrical charge and vice versa means converts applied electrical energy in to mechanical strain energy. This study suggests examining and testing a vehicle suspension system which was connected by the energy harnessing circuit that was designed, modelled and tested. Primarily analyses the kinetic energy absorbed in conventional Glamour bike (BS6) and later by Hero NYXe5 electric vehicle (EV) in running condition and observes the voltage generated based on the vibrations developed over the distance travelled in kilometres under the application of loads , the voltage generation is by the kinetic energy in the form of vibrations and are converted using piezoelectric materials through rectifier circuit, later harvest the energy get in dead rechargeable battery of 6V, 12V and improves by using the boost converter and the harvested voltage helps to recharge smart phones, air buds, low powered electronic devices. More the number of piezoelectric coils the higher the voltage can be harnessed. Finally focusses on incorporating nanomaterials in the design of piezoelectric energy harvesting system due to the unique properties of nanomaterials at the nanoscale to enhance mechanical and electrical properties and compared the obtained output voltage using PZT (Lead zirconate titanate) coils to PVDF (Polyvinylidene fluoride)-PZT nanocomposite film even for small application of force produces high voltage recommends the optimal solution of choosing nanocomposites.
