Controle, gerenciamento e recuperação de energia em veículos a combustão interna.

Abstract

In this work, the goal is to propose a regenerative braking system for an internal combustion engine vehicle, evaluating the energy viability to implement the start-stop function using only the energy recovered during the braking process. In order to do so, it is developed a detailed simulation model of the Lundell alternator aiming to validate the strategies that maximize its power generation capabilities. It is proposed a new maximum power point tracking technique that is both accurate and fast. This strategy is then applied to a vehicle braking scenario and the recovered energy amount is accounted for. The results point to both efficient maximum power point tracking during the braking process and energy viability to implement a start-stop scheme by using mostly devices that are already present in the system and avoiding drastic changes.
