In the paper it will be presented the history of electric vehicles (EVs), compared to conventional combustion engine cars. Environmental impacts produced the necessity of a cleaner transportation by reintroducing electrical cars in the automotive market. By increasing the EVs used in transportation, the level of pollution is decreased, but some major issues concerning electromagnetic compatibility are raised. The ambient electromagnetic field was described, focusing on simulation of a MV power distribution line. Afterwards, it was analyzed the electromagnetic interaction between an electric vehicle and the power distribution line, simulating the magnetic field distribution.

Grid Level

In this paper, a vehicle–grid integration (VGI) control strategy for radial power distribution networks is presented. The control schemes are designed at both microgrid level and distribution level. At the VGI microgrid level, the available power capacity for electric vehicle (EV) charging is optimally allocated for charging electric vehicles to meet charging requirements. At the distribution grid level, a distributed voltage compensation algorithm is designed to recover voltage violation when it happens at a distribution node. The voltage compensation is achieved through a negotiation between the grid-level agent and VGI microgrid agents using the alternating direction method of multipliers. In each negotiation round, individual agents pursue their own objectives. The computation can be carried out in parallel for each agent. The presented VGI control schemes are simulated and verified in a modified IEEE 37 bus distribution system. The simulation results are presented to show the effectiveness of the VGI control algorithms and the effect of algorithm parameters on the convergence of agent negotiation.

According to the Parallel Hybrid Electric Vehicle (PHEV) demands on powertrain systems, the dynamic models of PHEV are built in this paper. Base on the analysis of dynamical characteristics of both internal combustion engine (ICE) and electric machine (EM), the dynamic ability and fuel economy performance of PHEV is presented. The paper focuses on the parametric design of powertrain on vehicle performance, which provided the theoretical foundation for PHEV design. The paper also puts forward the control strategy of PHEV during the operating modes switching, which aims to solve the problem of the power distribution between the ICE and electric motor, which can effectively resolve process control problems of the complex PHEV system. By employing the dynamic model and performing MATLAB simulation, the results of simulation are given, which demonstrate that the PHEV improve performance well.

The work is devoted to the urgent issue of the invention and development of foreign and domestic electric vehicles, which is one of the possible directions in solving the issue of environmental conservation. Almost 80% of the global automotive market is heading for a ban on gasoline and the switch to electric cars and hybrids. However, this movement was, until recently, leisurely, if not slow. The popularity of electric vehicles in the world is due to the fact that they have several advantages compared to cars with an internal combustion engine. The principle of operation of an electric vehicle is based on the fact that the movement is provided by the operation of an engine that uses electric energy for its work. The electric motor plays the same role as the internal combustion engine, in addition, in the electric car, it is possible to install several engines that are able to distribute energy more efficiently and more rationally. Batteries play the function of a fuel tank, which supplies the engine with the energy necessary to ensure the movement of the car. For Ukraine, innovation is very important for the development of our country. Constant demand makes it clear that the future of electric cars. Ukrainians are paying more and more attention to such passenger cars, or hybrid ones. Every year the number of registered electric vehicles becomes more and more. The article highlights the main stages of the development of electric vehicles and presents the main problems of these vehicles, which indicate that they tend to be constantly improved.

AbstractThe automotive market is changing. For many years, cars with internal-combustion engines were dominant. Recently, more cars with alternative drive trains have become available, and their market share has increased, a trend that has had an effect on the remanufacturing industry for automotive parts. This paper aims to describe and evaluate the challenges and opportunities in the coming years for the remanufacturing industry as a result of the increasing number and share of electric vehicles. Both theory and empirical data have been used to meet this aim. From theory, the two different drive train concepts of the internal combustion engine and the battery electric vehicle are described, along with the major differences from a remanufacturing standpoint. These differences and effects are described, evaluated, and fully or partly confirmed by industry experts. The results show that future market actors are unset today, less space-consuming machinery parks will be needed, major investments into knowledge and equipment (especially for testing) will be required, and the necessity to handle different kinds of end-of-use/life solutions, especially the recovery for the electric vehicle battery packs, will be a challenge. As future development is still uncertain, the authors recommend that market actors investigate the challenges and opportunities highlighted in this paper and watch future developments carefully.

The Stability

The electric power distribution grid directly serves the ordinary users, the stability and reliability of which are crucial to production and life. The traditional operation and maintenance of the distribution grid is based on experience and cannot scientifically predict the state of line faults. In this paper, stepwise regression is used to screen out 8 key influencing factors of line faults, and principal component analysis is performed to find the risk value of each line; so that establishes multiple linear and exponential regression equations for the line risk value. According to the existing data, the risk of the line is predicted, and the GABP neural network model is built so as to accurately predict the risk value of the line.

Further Development

Electric vehicle gives much more advantages than only less air polluting or less noisy mobility. The current technology enables engineers to better control the electric motor than internal combustion engine. Electronic components like transistors, which can be switched on and off almost anytime, help to control the motor current and indirectly the torque and the speed. The progress in power electronics and motor construction opens new possibilities in vehicle construction and control. The process of wheel rolling can be better controlled which is very important especially on deformed surface of a road. The movement resistance can be reduced by smart power distribution between front and rear wheels in 4 × 4 drive vehicles, where front wheels can compact the ground and rear wheels can move on the rigid road. To reach all the advantages, we need a better understanding of a processes occurring in electric vehicles’ systems, which consist of motors, gears, and wheels reacting with ground. Authors present the model of 4 × 4 drive vehicle focused on this last, but not least, problem—part of an electric vehicle model which is the wheel–ground cooperation. This subsystem decides about power flow from the motor to the wheel and about traction and movement efficiency. This problem is not new, but flexible driving manner going with electric drive makes these analyses more practical and can be used in off-road electric vehicles. The analyses were supported by model and simulation prepared with MATLAB/Simulink software. In conclusion, the comparison of various drive properties and possibilities is presented and recommendations for further development are suggested.
