The performance of the Optimisation and Regenerative Braking systems by using PI controlling technique for Electric Vehicle (EV)

Abstract

Abstract Electric automobiles have lower fuel costs because electric motors are more efficient than internal combustion engines. These automobiles can only drive a certain distance because to insufficient batteries and the lack of charging stations. EVs, on the other hand, lack a short driving distance and require frequent charging and discharging of power batteries. EVs will benefit from the development of energy-saving technologies that will expand their reach and prevent battery damage caused by frequent charging and discharging. The goal is to improve the energy efficiency of braking system and its motor efficiency to generate current, as well as to improve regenerative braking (RB) efficiency in EV’s. Using a Brushless DC (BLDC) motor by adding an LC filter is the method that will be applied. A significant addition of current and less ripple and spike in the torque and a quick dynamic interference is the desired result. The performance of the system optimisation and RB circuit systems by using PI controlling technique. The output from torque produced by a 2200 Rpm is 3 Nm and demonstrates that the BLDC motor is efficient when driven by an LC filter circuit. Finally, using the Matlab/Simulink tool, this research presents a thorough simulation of a BLDC motor’s operation as a motor and a generator with RB to create more current in EVs.
