“…The charging station is useful in this interest to make the EVs functional. It is up to the general customer to adopt EVs and the utility grid to inject more renewables into grid so that the energy EV draws is clean [52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68].

The expansion of electric vehicles made the expansion of charging infrastructure rudimentary to keep up with this developing technology that helps people in a myriad of ways. The main drawback in electric vehicle charging, however, is the time consumed to charge a vehicle. The fast charging of electric vehicles solves this problem thus making it a lucrative technology for consumers. However, the fast charging technology is not without its limitations. In this paper we have identified the technology gaps in EV fast charging stations mostly focused on the extremely fast charging topology. It will help pave a path for researchers to direct their effort in a consolidated manner to contribute to the fast charging infrastructure. A thorough review of all aspects and limitations of existing extremely fast charging (XFC) stations have been identified and supporting data are provided. The importance of DC power network based on free fuel energy sources and silicon carbide-based power electronics are proposed to provide ultra-low cost and ultra-high speed XFC stations.

“…As mentioned above, to enhance the reliability of smart stations, it is necessary to provide an adequate adaptive protection and fault management method for the supply grid of these stations. However, the existing protection methods, such as methods presented in [29,31,37], are not only able to provide an ad adaptive protection (that is needed for the grids that are fed by renewable energy resources), but also cannot restore the grid after a fault occurrence, effectively. To overcome these issues, this paper presents a communication-based protection and fault management method that is able to adapt relays' setting after a change in the network topology, RES' output power or disconnection/re-connection of the utility grid.…”

“…Both AC and DC systems were suggested in previous work as the supply grid of charging stations. However, due to the advantages of new emerging DC distribution systems over the AC counterparts [29], especially in the grids that include many converters, DC systems were introduced as the supply grid of charging stations [16,30,31]. DC systems are also used to facilitate the integration of RESs to the station's supply grids, which can provide clean sources for the smart stations [32,33].…”

Expansion of electric vehicles' (EVs') charging stations is an unavoidable requirement in sustainable cities. Provision of safe protection and control infrastructure is one of the most important requirements for a reliable charging station. In this direction, a centralized protection, control and monitoring unit (PCMU) for smart charging stations is proposed here. PCMU communicates with chargers of the station, protective devices (e.g. relays and circuit breakers), local generating units and all other devices installed at the charging station to determine the station status and to detect/locate faults that may occur in the supply grid of the station. The PCMU includes a self-healing technique which is one of the specialties of smart systems that assists network reliability to increase. One of the major contributions of this research is to propose a protocol for data exchange between the PCMU and the other components similar to the logic used in standard of IEC 61850. Also, potential impacts of implementation of the proposed unit on the most-widely used reliability indices are discussed. The proposed protection strategy is examined via two case studies.

This paper helps to understand the configuration of grid connected EV charging station which is integrated with Renewable energy system. Which is an Solar PV rooftop system and act as a backup system for meeting power demand of an EV charging station which help to reduce stress on grid. Renewable energy sources is an best solution for production of energy as an local generation of power which help charging station run economically as it collaborate with grid connected charging station at off peak period the power is taken by grid for operation of station and at that time the solar pv system charges the backup batteries which are connect to station for supplying power to charge EV's at peak hours .As well as the backup battery bank which charge whole day with Solar PV system can be used for battery swapping for EV's .MATLAB/SIMULINK is used to simulate the grid connected EV charging station with renewable energy sources which help to obtain results of simulation model .
