Abstract

The autonomy of electric vehicles is under investigation by the scientific community,in which different solutions based on renewable energy resources, such as the photovoltaic, areproposed. A solution under study is the utilization of regenerative braking developed by theelectric motor vehicles. In this work, the addition of a regenerative braking is proposed aimingto increase the autonomy of electric bicycles. A two level, three-phase converter is applied todrive a brushless DC motor (BLDC). A comprehensive modeling of current and speed control arepresented in order to operate the machine in quadrants I and IV. The behavior of the Lithiumbattery charge is observed through its state-of-charge (SOC). Simulation results were obtainedby means of the SimPowerSystemsR©/Matlab/SimulinkR©software.
