Regenerative braking and damping are effective approaches for electric cars to extend their driving range. A disk Faraday generator regenerative braking strategy integrated with controlled charging of a supercapacitor is developed in this article to advance the level of energy-savings on the car board. The kinetic energy of the car suspension during driving regenerated effectively to electric energy by using shock absorber is harvested and then used to charge the vehicle’s battery, the power electronics and the supercapacitor. One of the advantages of supercapacitors is their high power capability, which is applicable for high rate of charging and discharging operations like motor starting and regenerative braking of an electric vehicle. This article presents a new charging method for supercapacitors. Common for regenerative braking and damping chargers for supercapacitors are usually equipped with electronic PWM converter performing two states of operation per switching cycle. A simple open-loop control system is applicable for the whole charging state. The proposed circuit consists of a minimum number of components. It is free of stability problem and protects itself from being overloaded by supercapacitor with zero initial charge. Simulation results for regenerative braking processes corresponding to three velocity tests are included.
