Abstract

The solution for range problems in electric vehicles is implying two essential approaches: consuming electrical energy with maximised efficiency and regenerative braking. Regenerative braking can be implemented by using the any converter used for electric motor control without needing an extra power circuit. To accomplish recovering electrical energy from mechanical energy a voltage boosting operation is necessary which is causing the current flow from induced voltage due to the mechanical motion to battery. In this study, a brushless DC (BLDC) motor drive system used for light electric vehicle propulsion is modeled by considering non-linear effects. The developed model of the motor drive system is used for defining the upper limits and constraints of operation. Analytic calculations and simulation results represent the operation modes of the system when regenerative braking is applied.
