“…Popular technical topics discussed in this category include quantitative analysis in various system designs, system configuration planning, modeling, control, and hybrid ESS (HESS) design for applications in ECSs [43]. In [44][45][46][47][48][49][50][51][52][53], the design and configuration of ECSs were discussed. M. Vasiladiotis and A. Rufer [44] proposed a modular multiport power electronic transformer based on a delta-connected cascaded H-bridge converter to incorporate a split-battery ESS for ultrafast EV charging service.…”

“…Later, the optimal capacity of an ESS on a given set of design conditions was studied in [49]. The design of a wireless flywheel EES for a fast charging station (WFFCS) was proposed by A. H. Fahad and H. A. Gabbar in [50]. V. Salapić et al [51] proposed a mixed integer linear programming (MILP) scheme for the optimal capacity and control of an ESS.…”
The optimal planning of electric vehicle (EV) charging stations (ECSs) with advanced control algorithms is very important to accelerate the development of EVs, which is a promising solution to reduce carbon emissions of conventional internal combustion engine vehicles (ICEVs). The large and fluctuant load currents of ECSs can bring negative impacts to both EV-related power converters and power distribution systems if the energy flow is not regulated properly. Recent review papers related to EVs found in open literature have mainly focused on the design of power converter-based chargers and power interfaces, analyses of power quality (PQ) issues, the development of wireless charging techniques, etc. There is currently no review paper that focuses on key technologies in various system configurations, optimal energy management and advanced control issues in practical applications. To compensate for this insufficiency and provide timely research directions, this paper reviews 143 previously published papers related to the aforementioned topics in recent literature including 17 EV-related review papers found in Institute of Electrical and Electronics Engineers (IEEE)/Institution of Engineering and Technology (IET) (IEEE/IET) Electronic Library (IEL) and ScienceDirect OnSite (SDOS) databases. In this paper, existing system configurations, related design methods, algorithms and key technologies for ECSs are systematically reviewed. Based on discussions given in the reviewed papers, the most popular ECS configuration is a hybrid system design that integrates renewable energy (RE)-based power generation (REBPG), various energy storage systems (ESSs), and utility grids. It is noteworthy that the addition of an ESS with properly designed control algorithms can simultaneously buffer the fast, fluctuant power demand during charging, smooth the intermittent power generation of REBPG, and increase the overall efficiency and operating flexibility of ECSs. In addition, verifying the significance of the flexibility and possible profits that portable ESSs provide in ECS networks is a potential research theme in ECS fields, in which the potential applications of portable ESSs in the grid-tied ECSs are numerous and could cover a full technical spectrum.

Demand for Electrical energy is ever increasing since independence. As on December 31 st 2019, installed capacity of India is 368.79 GW, out of which 34.86% is renewable. With time, demand increases. Current renewable energy systems are not efficient. Either improvement is to be proposed or new technology is the need of the hour. Our team is proposing generation of electric energy that can be used to charge batteries or other devices using a rotary leverage system. Proposed system is efficient, environmentally friendly and inexpensive.System uses a flywheel that stores excess energy and even when input power is low the system gives a constant output.
