This study describes the development of a model of an electric vehicle (EV) with a smart battery-powered inverter-controlled induction machine drive system. The computer simulation model in MATLAB Simulink is used to estimate the energy and power requirements of vehicles over standard driving cycles under various driving conditions. Here, using smart logic for battery performance, factors affecting range and energy use help to optimize the maximum efficiency of battery and motor performance. So, the study is used to review different motor drive systems in EVs. According to these researches, some conclusions have been obtained. The main focus of the study is on control techniques that are being applied to make AC drives a rapidly growing area. So, the overall research is to develop mathematical modeling with simulation results to compare experimentally the transitional characteristics of the electric drives in various operating modes. The new algorithm used to achieve the energy-efficient performance of EV-motors is based on the self-commutated current inverter with a relay regulator of stator current. This inverter has IGBT-based switching with PWM and additional cutting diodes and buffer capacitor blocks. From this, switching operation with VSI operation produced output of inverter nearly sinusoidal with lower harmonic distortions. Scientists try to enhance energy densities, ranges and quicken the charging. Hence research is required to be done for interconnecting EV components in an intelligent way for motor drives with battery systems. Electric motor and battery, both are the most important components in EV with the function of the motor at a frequent stop, start, slow down and acceleration, and it can realize the needs of high starting torque and better speed regulation, simple and reliable operation and long service life. This characteristic consists in induction motors suitable for acceleration tests, where simulated induced torque, rotor speed, mechanical output power, efficiency, slip and stator current waveforms were generated accordingly. Hence the mathematical Simulink model was developed to analyze the IM drives' performance for electric vehicle application. The type of inverter used in the 3-phase AC drive model is a voltage source inverter (VSI) in the sense that this inverter is fed by a constant DC voltage. This stabilized voltage with controlled rectifiers and bidirectional converters to charge (capacitive DC bus voltage). In this model of closed-loop system, we have error detection for both speed and current with respective controllers which can provide controlled PWM voltage and frequency signals applied by the six-step inverter in order to maintain the (V/F) ratio constant. The control uses PI-Type with deferent PID values of tuning for AC machines controlling used as vector-controlled drives. It has two main functions: to achieve high starting torque with limiting high in-rush current losses which affect the performance. The second and most costly part of the power source in EV-system is battery technology to do research on the modeling and state estimation of batteries, which is essential for optimizing energy management, extending the life, application cycles, and thermal optimization of batteries in EVs. Finally, the current work also highlights a number of key factors and challenges and presents the possible recommendations for the development of next-generation of smart SoC estimation and battery management systems for electric vehicles and battery energy storage systems.

This project was conducted to analyze (model and simulate) and optimize an electric motor based drive system to propel a typical passenger vehicle in an urban driving environment. Although there are many HEV and EV type systems on the market today, this paper chose the Toyota Prius HEV system as a baseline using a brushless AC motor.
Although a vehicle can be driven many ways, a more standardized Urban Dynamometer Driving Schedule, UDDS, was chosen to simulate real driving conditions. This schedule is determined by the US Environmental Protection Agency, EPA, and is intended to represent the city driving conditions for a typical passenger vehicle in a city environment.
A high level modeling and simulation approach for vehicle and motor drive was taken to focus on motor operation and gear ratios from the electric to the mechanical drive system.
Vehicle battery being the limiting factor in the range of the HEV vehicle, the energy usage of the battery was optimized to ensure lowest energy dissipation, thus gaining the most mileage out of the vehicle.
How to maximize the drive mileage for a given battery size? There are multiple dynamic factors that affect the battery usage and efficiency. Factors such as road conditions, vehicle speed, weather, weight, and aerodynamics are amongst the many that govern battery mileage. Gear ratios and selection also play a crucial role in the loading and efficiency of the motor, thus affecting the battery mileage.
In this project, the gear ratios between the electric motor and the vehicle drive shaft were the focus for this optimization. As part of the overall system model, gears and gear ratios were modeled and simulated to determine their optimum ratios for finding the minimum energy usage point for the battery.

The aim of the article is design of DC/DC converter and discussing of
problematic supply using electric power splitter. The electric power
splitter with AC/DC converter is source for the DC/DC converter, which
is dedicated for charging and discharging of hybrid car drive
super-capacitor energy storage. The electric power splitter is
synchronous machine with two rotating parts. First rotor contains
permanent magnet and the second rotor contains three-phase windings. The
amplitude of output voltage depends on difference between first and
second rotor speed. The main role of the DC/DC converter is to optimize
energy content in super-capacitor storage used to acceleration and
deceleration driving period of the passenger car with hybrid electric
vehicle (HEV) drive system using electric power splitter.
The production of energy for traction in classical vehicles is performed by petrol or oil combustion. The consequence is green gas production. Paper deals with different power trains of electric hybrid and electric vehicles. Electric hybrid vehicles diminish the fuel consumption by giving to the internal combustion engine (ICE) better working conditions with respect to ICE revolutions and demanded power. The kinetic braking energy recovery is an important feature too. Electric vehicles are usually called "green vehicles". It is true that they do not produce green gas on places where they are driving but it is also true that their traction energy has to be produced with another energy technology used in electric plants. The efficiency of the vehicle powertrain is important. The energy for transportation by vehicles in the world is great. Therefore it is very important what energy production technology for this traction purposes will be used.
For vehicle comparison from point of view of green gas production it is necessary to add to the green gas production of the vehicle itself also the quantity that was necessary to produce the fuel for internal combustion engine ICE or the electric energy for electric vehicle. Only this attitude is objective. This paper reveals simulation results of CO2 emission produced by different types of car drives. Although electric vehicles are assumed like “zero emission vehicles” their CO2 path in dependence on the sources and technology of electric energy production (electric energy mix) is here calculated. In paper Hybrid Electric Cars with Combustion Engine driven cars are compared. This paper compares Electric cars with Combustion Engine driven cars.
