The evaluation of regenerative braking energy

The goal of the present contribution is to describe some special aspects presented on literature, in order to understanding the dynamic performance of car equipped with Regenerative Breaking System and preliminary work for building one practical implementation for commercial cars. During deceleration, these vehicles are able to recuperate energy of motion as electrical energy with their built-in electrical motor which then functions as generator. This electrical energy is buffered in a battery in the vehicle, and converted in kinetic energy through the electrical motor during next acceleration process. According to the design of the electrical motor / battery combination, a reduction of the fuel consumption can be achieved between 5% and 20%. Also the compliance of the emission limit value is being alleviated through the hybrid traction. The author´s propose a study for evaluate these energy and regarding the opportunity to use super-capacitors for handle these stored energy.
