Fabrication and testing of electromagnetic energy regenerative suspension system

Abstract

The world is demanding for alternative way of energy consumption for vehicle usage. The en-ergy efficient vehicle (EEV) is one of the advancement for future land transportation that known as hybrid and electric vehicles nowadays. The vehicles use different energy other than fuel which is electric energy. This paper emphasizes the development of electromagnetic energy regenerative suspension system (EReSS) as a system that harvests energy from the vibration of vehicle suspension system. The harvested energy is converted to electrical energy for vehicle usage. A prototype of electromagnetic EReSS is fabricated and laboratory experimentation on test rig is conducted to test the voltage output. It is observed that the EReSS can harvest the wasted energy from the vibration and produce sufficient electric energy for the vehicle electri-cal and electronic usage. The number of windings of the coil and diameter of the coil affect the voltage output of the EReSS. The voltage output of the EReSS can be optimized by setting up the parameters. As the EReSS is proven to harvest energy, it can be used on hybrid and electric vehicle to improve the efficiency of the vehicle and reduce the fuel consumption.
