The electric vehicle (EV) charging systems employ dc-dc power converters as EV chargers. Currently, the expected high penetration of electric vehicle (EV) demands for the integration of the renewable energy sources (RES) into the electric vehicle charging system as a promising solution to cut down the load on the electrical grid. These systems interface with RES by implementing dc-dc power converters. Moreover, with the advent of high-power dc charging, the charging efficiency is largely dependent on the performance of the power converters. Hence, to improve the charging, the soft switching dc-dc converters are implemented to maintain low switching losses and to achieve high-efficiency operation. This paper reviews the non-isolated, soft switching dc-dc power converters for EV charging application. For this purpose, different types of soft switching topologies, namely the snubber, the series resonant, the shunt resonant and the pulse frequency modulated converters are investigated. The advantages and the disadvantages associated with these converters are highlighted. Furthermore, to perform a comparative evaluation, the topologies are simulated in a standard simulation platform. Consequently, the relative standing of the converters depending on several parameters, i.e. the component count, the output voltage and current ripple, the soft switching range, and the power losses are established. Finally, based on these results, the optimum applicability of the converters in the EV charging application is determined. GUB JOURNAL OF SCIENCE AND ENGINEERING, Vol 6(1), Dec 2019 P 60-74

Modern Era

Electric Vehicle is one of the most emerging technology in modern era. Different type of latest technologies are used in today’s electric vehicles as well as the battery technology is also developed. Besides many advantages of electric vehicles there are some bad impacts of electric vehicles charging on electric grid. Analysis of Electric Vehicle charging impacts on distribution grid are highly importance for the development of electric vehicles. In this paper a very simplified model is used by MATLAB/Simulink to analyze the Electric vehicle charging impacts on distribution grid. In this model Vehicle to grid (V2G) technology is also used to analyze the grid power. The active power of distribution grid was measured while EVs were charging for both V2G on and off cases and the differences between this two conditions were measured from the simulation and the results were compared.  In this paper the impacts of EV charging on other grid connected loads are also analyzed.

The electric vehicle (EV) charging stake is widely used for recharging the electric car batteries. The charging stake generally adopts switching power supply technology. It will cause serious harmonic pollution to power systems and consume lots of reactive power. Therefore, this dissertation focuses on the active power filter (APF) for the EV charging stake. Firstly, the principle of the APF are briefly introduced. Secondly, the main design and the technical difficulties are illustrated in detail. The controller of the APF is based on the DSP and the model is TMS320F2812. At last, this study is simulated in Matlab and a prototype is constructed. The simulation and the experimental results prove that the APF can functions well for the electric vehicle charging stake. It has achieved the national power quality standard.

Owing to several advantages of Plug-in Electric Vehicles (PEVs) like less noise, emission less, good efficiency and the reduced cost has attention to the governments, researchers and manufactures in recent time. The Plug-in Electric Vehicle (PEV) plays a vital role in    replacement of conventional vehicles in future, because of penetration of renewable energy resources in conventional generation. The modernized of micro grid is happening due to usage of clean energy for EV charging. The cost of electric vehicle charging is challenging issue in the development of plug-in electric vehicle. The coordination between renewable generation and conventional generation is very much needed in near future. The dynamic nature of renewable energy resources causes frequent interrupts in electric vehicle charging. The problem of nonlinear power generation with renewable resources is overcome by electric vehicle battery storage system which   enables the EV battery to charge during low demand period and gets discharged into the micro grid during high demand periods. This paper developed an optimal schedule for stationary Plug-in Electric Vehicle charging in operation with micro grid. The obtained optimal schedule provides balance between active and reactive power in generation and load as well. The integration of renewable energy resources is achieved through solar, wind in Vehicle-2-Grid (V2G) approach which is used to safeguard to renewable energy resources by store additional energy produced during peak load period and feeding back to the micro grid during low load period. As a result the stable operation of the micro grid and EV charging with low cost is achieved in this paper.
