This paper proposed a novel kinetic energy harvesting model that is installed under the speed bumps to harvest power wasted by vehicles when they pass over the speed bumps. The model consists of three main parts: drivetrain-pump-storage system, generator module, and control module. Acting as an energy input, the drivetrain-pump system harvests kinetic energy to produce compressed air. The storage system then stores this air so it is ready to discharge to the generator system. When compressed air is discharged into the generator module, this module will generate electrical energy which can be charged to a battery. The control module can automatically monitor and adjust the amount of compressed air and power in the battery. Tests have shown that the system is capable of storing a compressed air volume below 50 psi. This energy allows generating 14.8VDC power to charge the 12VDC battery. The initial results allow further research for a new energy source in the future.
