Pendulum-based mechanism for energy harvesting from automobile movement

With the increasing demand for sustainable and auxiliary energy solutions, innovative energy harvesting techniques are gaining more traction. This study explores the application of a pendulum-based energy harvesting mechanism in vehicles, utilizing the natural oscillations induced by vehicle movement to generate electrical power. In the current article, a pendulum-based mechanism is developed for energy generation in vehicle applications. The article presents theoretical analyses of motion dynamics, energy conversion efficiency, and system integration feasibility. The developed mechanism is designed for vehicle applications to be excited by car motion. The calculation results indicate the applicability and how effective the developed mechanism is. The proposed design should be fabricated in a small size and lightweight to be installed in the back trunk of the car or other parts where it can be fixed, preferably close to the suspension system, to have higher excitation.
