Proposal of an energy management architecture applied into a regenerative braking system

Abstract

Regenerative Braking in vehicles is projected as an intelligent and simple technique to improve the energy replenishment and autonomy in them, due to the fact that it is based on the concurrent process of deceleration. It is smart because takes advantage of the capability of the electric machine to behave as a generator. So, it is possible to recover the kinetic energy store in the rotating inertias by using regenerative braking during the deceleration and restore it into batteries. Some authors are focused on maximizing the energy regenerated, applying techniques as independent factors of the process, like storage elements, control of speed, acceleration, current, etc. In this work we exposes the regenerative braking process and its main parts in a holistic model, where discrete and continuous states and events are related, also linked into the dynamic behavior, bringing the possibility not only to have a general model that commands all the process, but also improve and monitor each stage as a whole. Thus our management architecture pretends to maximize the gain energy in every deceleration, and minimize the energy consumed.

Critical review on optimal regenerative braking control system architecture, calibration parameters and development challenges for EVs

“…EVs require an efficient braking controller for optimal braking performance and safety. The purpose of RBS is used to improve the regenerative energy efficiency, braking stability, and performance in the vehicle 44 . The control architecture of the RBS has various subsystems such as brake controller, regenerative brake controller along with brake control strategies, etc, as shown in Figure 5.…”
