With the advent of Electric Vehicles into existence, there is a need to develop a significantly charging infrastructure that will make electric cars more attractive and lead to higher adoption rates. In light of the increasing demand for EVs, there is a need to develop a fast‐charging station that cuts back on the charging time and hence overcome range anxiety. Fast charging stations are capable of reducing the charging duration by up to 30 min. By way of sustainable development and availability of secure energy, the focus of the paper is to develop the fast charging station of various Electric vehicles/Plug‐in Hybrid Electric vehicles as per the grid power supply and their worldwide implementation. In this paper, we have designed a system for the fast charging of electric vehicles in which we provide continuous feedback to the dc‐dc converter considering the battery SOC by using a battery pack control module and tuning the PI controller. To reduce the fluctuation in input supply, we have studied and implemented a cosine firing scheme based voltage regulator and electronic tap changer (ETC) out of which ETC provides a very promising solution. Further, the impact of charging with time on battery resistance has also been discussed.

“…The second requirement is the electrical quantities (voltage and current) ripples as the output of the converter which is set to a very narrow value to guarantee secure operation of the converter and prevent any damage to the connected battery pack [23]. In fact, the maximum current and voltage ripples are set at 5% and 1% of the nominal value, respectively [2], [11], [24]. Another requirement is the ability to deliver high power to reduce the charging time to less than 15 minutes.…”

This paper introduces a level 3 charging system which aims to reduce the charging time to less than 15 minutes with 350 kW charging power. Two architectures of a fast charging station based on the isolation requirement through low and high-frequency transformers are introduced and discussed. Focusing on the DC-DC charging stage, this paper also provides a detailed comparison of the Dual Active Bridge (DAB) converter and the Interleaved Buck Converter (IBC), which are considered as two of the most suitable converters that can serve as a fast DC charger. Technical evaluation and comparison based on different performance indices such as volume, efficiency, number of components etc. as well as simulation of the two converters are presented. Finally, comparison results are introduced and a final discussion and conclusion are presented on which topology seems more optimum to be used as a fast DC charger.

“…Depending on the number of EVs, network characteristics and charging capabilities of EVs, effects on the power quality can be significant or negligible. As a consequence of the volatile nature of EV charging, problems of increased peak demand and decreased lifetime of a transformer might also arise [12]. For these reasons ongoing research into the topic of charging strategies is popular [13][14][15][16].…”

“…EV chargers contain non-linear power electronic devices, for instance AC/DC converters. Due to this fact, the endurance and performance of distribution network equipment might be affected (additional losses in cables and windings of the power transformers) [12]. EV charging must meet harmonics and voltage requirements as specified by EN 50160, IEC 61000-3-2/3-12 and IEEE 519 standards.…”

Electromobility is becoming an increasingly popular topic mostly thanks to its positive environmental impact. Replacing combustion engine cars with electric vehicles seems to be a matter of time. Electric cars have many advantages, but their impact on a power quality must be taken into consideration. The article describes current status of electromobility and problems related to the influence of charging stations on a power system. The issue of standardisation of electromagnetic compatibility requirements for charging stations is also discussed.
