Abstract

Nowadays, the enormous amount of energy dissipated as heat during braking a vehicle is a recurrent worry considering the shortage of energy resources. In this context, regenerative braking presents itself as an alternative to reduce such energy loss by improving vehicle's performance. This research intends to study the relevance of energy recovery in hybrid vehicles and the impacts of its application. Therefore, an extensive research on braking, regeneration, motors and batteries will be developed to fully comprehend the involved systems, supplying the necessary basis to obtain hypothetical and empiric data about regenerative braking efficiency. Data acquisition will occur through computational simulations assisted by software, using vehicle modeling. Later on the simulation's verification will be accomplished through experiments at the Integrated Systems Laboratory (LabSIn) of the School of Mechanical Engineering of UNICAMP, which has run a bench equipped with a system of kinetic energy recovery through regenerative braking via Flywheel. Positive results are expected, what means effective fuel consumption shortage, in an economically practicable way, aiming to reduce the carbon footage print of the automobilist industry.
