Electric cars are becoming more and more popular. In 2019, 2.2 million electric cars were sold around the world, and that number increased in 2021 to 6.6 million. Microgrids prove to be a viable resolution to the challenge of integrating large-scale electric vehicles and renewable energy sources into the electric power system, given the exponential expansion of both industries and the demand for electric vehicles (EVs). Additionally, the principal policy objective of the government is to enhance the accessibility of public recharge stations designed to accommodate EVs. The study applies cutting-edge technologies to the development of fast-charging (FC) stations. Because DC charging offers unlimited power and quick power transfer, vehicle-to-grid technology can be implemented in a microgrid using DC power transmission. However, incorporating EVs into a microgrid system presents some operational difficulties. In this study, these difficulties are related to power quality (PQ) problems like harmonics in power systems, which have an impact on consumers as well as utilities. The efficacy of the control system was assessed through the simulation of design models employing MATLAB-based vector control and constant current-constant voltage (CC-CV) techniques. Through the reduction of the system's total harmonic distortion (THD), both strategies contribute to the enhancement of the PQ and performance of the control system as assessed by these simulations. Based on the findings, the controller demonstrated a decrease in THD and an enhancement in waveform quality, resulting in high accuracy and good performance. The DC-Bus receives power transmission from the AC network that is near the unity power factor (PF) and is distinguished by a sinusoidal current.

“…The charging standards in India are being adopted from IEC as well as from GB/T and modified according to the local market (Type 2 AC Mains, Bharat DC-001, and Bharat AC001). Three dedicated standards have been developed for DC fast charging: a) Combined Charging System (CCS) [196], b) CHArge de Move (CHAdeMO) [197], and c) Supercharger (Tesla Vehicles) [198]. Mostly all these standards have been developed around the National Electrical Code (NEC) article 625 by National Fire Protection Association (NFPA) and have been presented in Table IX.…”

“…Both, the Type 2 and the Combo 2, as well as the CCS 2, charging plugs and sockets are recognized in North America under the recommended practice of the SAE J3068 [36], "Electric Vehicle Power Transfer System Using a Three-Phase Capable Coupler". Another (globally) popular charging system is the CHAdeMO system [39,40] (for DC charging), which stands for "CHArge de MOve". However, especially due the EU directive 2014/94 [21], the CCS 2 is becoming dominant in Europe in comparison to the CHAdeMO system.…”

Battery electric vehicles demand a wide variety of charging networks, such as charging stations and wallboxes, to be set up in the future. The high charging power (typically in the range of a couple of kW up to a couple of hundred kW) and the possibly long duration of the charging process (up to more than 24h) put some special requirements on the electrical infrastructure of charging stations, sockets, and plugs. This paper gives an overview of the technical design requirements and considerations for vehicle charging stations, sockets, and plugs, including their infrastructure, according to the Swedish Standard 4364000, “Low-voltage electrical installations—Rules for design and erection of electrical installations”, and the corresponding harmonized European standards. In detail, the four internationally categorized charging modes are explained and the preferable charging plugs, including their two-bus communication, according to European Directives are shown. The dimensioning of the supply lines and the proper selection of the overcurrent protection device, the insulation monitor, and the residual current device are described. Furthermore, a comprehensive overview of the required safety measures, such as the application of an isolation transformer or the implementation of an overvoltage protection mechanism, and the limits for conducted electromagnetic emissions, such as low-frequency harmonics or high-frequency (150 kHz to 108 MHz) emissions, are given.
