Optimal Design and Operation of Fast Charging Station for Electric Vehicle Via Renewable Energy in Wadi El-Natrun-El Alamein Road, Egypt

This paper focuses on the design of a charging unit for an electric vehicle fast charging station. With this purpose, in first place, different solutions that exist for fast charging stations are described through a brief introduction. Then, partial power processing architectures are introduced and proposed as attractive strategies to improve the performance of this type of applications. Furthermore, through a series of simulations, it is observed that partial power processing based converters obtain reduced processed power ratio and efficiency results compared to conventional full power converters. So, with the aim of verifying the conclusions obtained through the simulations, two downscaled prototypes are assembled and tested. Finally, it is concluded that, in case galvanic isolation is not required for the charging unit converter, partial power converters are smaller and more efficient alternatives than conventional full power converters.

Fast Charging Station

This paper proposes the design and dynamic analysis of a possible topology of Electric Vehicle Fast Charging Station (EVFCS), which interconnects Photovoltaic Generator (PV); Stationary Batteries (SB); DC Bus; Electric Vehicle (EV); Power Switches; DC-DC Power Converters (Buck, Boost, and Bidirectional DC-DC Converter); Bidirectional AC-DC Converter; High Frequency Transformer (HFT); Matrix Converter (MC) and LCL Filter, with the possibility of connecting to the Utility Grid. The Stationary Battery will be charged slowly through the Photovoltaic System in the morning and afternoon hours and by the Utility Grid at night. Later, the Stationary Batteries will be discharged and will charge the Electric Vehicle Battery quickly (about 20-30 minutes) through a Bidirectional DC-DC Converter and through the Utility Grid, but with an effort much less to process high power in short time intervals in the distribution transformers. The power and control projects of the system were performed through calculations and validated by performing simulations. The simulations will be done in MATLAB / Simulink software. Three operating scenarios will be created, where the use or not of the Utility Grid will be analyzed, according to the intermittent of the Photovoltaic Generator, the State-of-Charge (SOC) of the Stationary Batteries and the Electric Vehicle. For this, there will be the management of the power flows that will be performed by Power Switches. The results indicate the effectiveness of the proposed strategies.

Variable Speed Motor

The paper proposes the adaptation of the industrial plant’s power network to supply electric vehicle (EV) fast-charging converters (above 300 kW) using renewable energy sources (RESs). A 600 V DC microgrid was used to supply energy from RESs for the needs of variable speed motor drives and charging of EV batteries. It has been shown that it is possible to support the supply of drive voltage frequency converters (VFCs) and charging of EV batteries converters with renewable energy from a 600 V DC microgrid, which improves the power quality indicators in the power system. The possibility of implementing the fast EV batteries charging station to the industrial plant’s power system in such a way that the system energy demand is not increased has also been shown. The EV battery charging station using the drive converter has been presented, as well as the results of simulation and laboratory tests of the proposed solution.
