Abstract
Recovering kinetic energy in an electric vehicle is important in order to use battery more effective and to extend the vehicle’s maximum distance range. In this study, regenerative braking is simulated and implemented on a test bed for a lightweight electric vehicle on the three different downhill that are 3o, 4o and 5o slopes at 30km/h conditions. An in-wheel motor which is generally used in the light electric vehicle is used for the regenerative braking application. Speed of the in-wheel motor is controlled with PID controller during regenerative braking. The in-wheel motor charges batteries and the PID controller maintain speed of the in-wheel motor to reference speed in both simulation study and experimental study. Graphics and outcomes of the simulation and experiment are showed in the results and discussion section. DOI: http://dx.doi.org/10.5755/j01.eie.23.6.19693
Highlights
Electric vehicle technologies are rapidly growing through the cheap and clean energy advantages; electric vehicles have a range problem
Regenerative braking control and management strategies are developed considering the temperature of batteries, motor and motor driver, charging current, battery voltage, deceleration, the pressure of braking pedal [11]–[16]
Subject of this study is different from literature mentioned above as cooperation braking, optimum or maximum energy recovery, stability control and management strategy of regenerative braking
Summary
Electric vehicle technologies are rapidly growing through the cheap and clean energy advantages; electric vehicles have a range problem. Friction braking and automatic transmission cooperate with regenerative braking as aimed optimum energy recovery [3]–[7]. Regenerative braking control and management strategies are developed considering the temperature of batteries, motor and motor driver, charging current, battery voltage, deceleration, the pressure of braking pedal [11]–[16]. Are some difficulties to execution of regenerative braking on real vehicles. For this aim, regenerative braking with IWM (in-wheel motor) is executed in simulation study with using Matlab/Simulink and experimental study on a test bed for based a 300 kg lightweight electric vehicle on 3o, 4o and 5o slopes downhill at 30 km/h reference speed. Subject of this study is different from literature mentioned above as cooperation braking, optimum or maximum energy recovery, stability control and management strategy of regenerative braking
