|1||Implementation Of Various Control Strategies In Hybrid Energy Storage Systems For Electric Vehicle Applications||1.Keerthi Upender, 2.G.Srinivas||
Electrical vehicles are very helpful in saving the environment. Hence, they are getting a lot of importance in the transportation system. The entire world is transforming towards the electricity-based transportation system. The main factor by which we can understand about the saving of energy is through the energy management process. The effective utilization of energy can be achieved by the energy management system.
Many energy management methods are proposed in the literature, which depend on the design, control, economy, and demand for that particular energy management system. The energy management systems can be implemented either offline or in online mode. The performance of the energy management depends on the control strategy implemented in the system.
In this paper, the effective methods of energy management methods that are suitable for electrical vehicles are studies and implemented. All the implementations are carried out in a MATLAB environment. The results for effective energy management systems are presented.

The best alternative for e mobility is electric-based transportation. The importance for electrical transportation increasing rapidly throughout the world due to the decrease in conventional fuels like petrol and diesel. In India, still, most of the transportation is using the conventional I.C. engine vehicles only. According to the surveys, it may take five to ten more years to replace all the existing vehicles with electric vehicles.
An electric vehicle or drive train requires several subsystems such as the battery, charging circuit, motor drive, converters, and other controlling circuits. Out of all the subsystems, the vital system in a vehicle is the electrical motor used in the electrical vehicle design. Several motors are available such as a three-phase induction motor, synchronous motor, reluctance motor, and brushless D.C. motor.
Out of all the motors, the more suitable motor for electric vehicle applications is the BLDC motor, which provides high torque under starting and running conditions. Hence, the vehicle will be effective by employing the BLDC motor. In this project, the model of the BLDC based electric vehicle is created, and the output waveforms are presented. The model of the vehicle is created in MATLAB/SIMULINK. The vehicle is operated under various conditions. The output waveforms of various subsystems are obtained.

Climate change and the greenhouse effect are the major motivational factors for the development of electric transportation systems word wide. The major components in electric vehicles are the motor, energy storage system, and control circuits. Out of all the major research areas in current trend are the charging technologies. Various charging techniques available are static charging, dynamic charging, etc.
Using the charging circuits of an electric vehicle, the power can be transferred from grid to vehicle and also from vehicle to grid. The power flow will be from the grid to the vehicle if the battery storage is less. But, it is possible to send back the power from vehicle to grid if the bidirectional charging circuit is employed in the vehicle. This requirement can be utilized during the lack of power produced by renewable energy sources.
In this paper, a bi-directional charging circuit for electric vehicles is designed and simulated. The charging circuit can send and receive the power in both directions. The simulation results of the charging circuit are shown and the waveforms related to the charging and discharging are also shown. Entire simulations are performed in SIMULINK.
