“…In addition, some EV manufacturers have created their own standards. For some manufacturers who prefer AC transfer in charging stations, the maximum power and maximum current in the stations, input voltage, connectors used for energy transfer, communication structures, and standards are shown in Table 2 [4,5]. Another important possibility is that the charging stations can be designed as a modular structure, which means that they can consist of multiple interchangeable units that can be easily configured or expanded based on demand and requirements.…”

“…Despite the slow charging process, high-power energy transfer during electric vehicle fast charging can reduce battery life and batteries may need to be replaced frequently. This additional and high cost is one of the biggest handicaps of this solution proposal [4,5,6]. However, the design and simulation studies carried out on Li-ion batteries in the following sections have shown that, depending on this battery selection, the costs are more reasonable than the existing fast DC charging stations in the 10year period.…”

Concerns over fossil fuel depletion, fluctuating fuel prices, and CO2 emissions have accelerated the development of electric vehicle (EV) technologies. This article reviews advancements in EV fast charging technology and explores the development of battery-assisted DC fast charging stations to address the limitations of traditional chargers. Our proposed approach integrates battery storage, allowing chargers to operate independently of the electric grid by storing electrical energy during off-peak hours and releasing it during peak times. This reduces dependence on grid power and enhances grid stability. Moreover, the transformer-less, modular design of the proposed solution offers greater flexibility, scalability, and reduced installation costs. Additionally, the use of smart energy management systems, incorporating artificial intelligence and machine learning techniques to dynamically adjust charging rates, will be discussed to optimize efficiency and cost-effectiveness.

The potential for improving sustainability in the transportation sector is considerable when renewable energy sources are combined with electric vehicle (EV) charging stations. The design methodology for a three-phase grid-integrated EV charging station that integrates renewable energy sources is presented in this paper using simulation-based design. The suggested system seeks to reduce grid dependency, maximize the use of renewable energy sources, and optimize energy management. Utilizing cutting-edge software tools, the simulation model is created to evaluate the integrated system's viability and performance under various operating scenarios. The study offers insightful information for the planning and development of sustainable transportation solutions and emphasizes the possible advantages of incorporating renewable energy sources into EV charging infrastructure.In this paper, a power predictive model was presented to forecast EVs power demand and to enhance the CS performance, in order to avoid an extra burden on the grid during peak hours. PV array with storage battery supported by the grid increased the reliability and flexibility of the system.

In this work, we present a photovoltaic (PV)-based off-board charging system integrated with the grid using a voltage source converter (VSC). The control of the grid-tied off-board charger is derived from the joint logarithmic hyperbolic cosine robust sparse adaptive filter (JLHCAF) algorithm. This algorithm effectively tracks the fundamental component of the load current in a short duration, providing a good dynamic response. Due to its robustness against impulsive interference, the JLHCAF outperforms other sparsity-aware robust algorithms The cascaded proportional-integral (PI) controller is used to control the bidirectional buck-boost converter for electric vehicle (EV) charging/discharging, which acts in buck operation if the EV is being charged and in boost operation if it is discharged. The reference DC link voltage for the controller is derived by using adaptive MPPT technique. The bidirectional properties of the system enable various functions, including grid-to-vehicle (G2V), vehicle-to-grid (V2G), PV source-to-grid (PV2G), vehicle-to-home (V2H), and PV source-to-vehicle (PV2V) operations. Additionally, the system can supply power to critical nonlinear loads. The control strategy ensures compliance with the power quality requirements set by the IEEE standard, as demonstrated in the results. To validate the effectiveness of the proposed system, we conducted tests under dynamic conditions by disconnecting and reconnecting household loads. Furthermore, the off-board charging system was subjected to actual conditions, such as variations in solar PV insolation, and its steady-state performance was evaluated through simulation and laboratory experimental prototypes. The results, including total harmonic distortion (THD), support the validation of the developed charging system.
