Abstract

India is the world's top producer of two-wheelers, which are frequently used in our daily lives. However, after a few years of service, the engine loses its efficiency and can no longer meet the environmental protection regulations. If these scooters could be transformed into electronic scooters, they could be used for a longer period of time. In this paper, an ordinary two-wheeled Honda Activa Scooter model powered by a two-stroke gasoline engine was converted into an electric vehicle. To increase efficiency, a novel approach known as regenerative braking was implemented. Regenerative braking temporarily conserves kinetic energy during deceleration and then uses it again as kinetic energy, thereby reducing fossil fuel consumption. When braking, a large amount of energy is typically lost as heat, but the regenerative braking system recovers this energy. With this system, the electric motor uses the vehicle's momentum to recover the energy lost while braking.

Abstract

Due to the peak energy and power density, the battery is a leading energy source for electric vehicles. Among various battery chemistries, Li-ion batteries have emerged as serious competitors in the field of electric vehicles. The battery cells are connected in series or parallel to increase voltage and current in a battery pack for electric vehicle applications. The heart of a battery-operated electric vehicle is the battery control system. The series-connected cells in a battery pack must preserve each cell's original potential under ideal charging and discharging conditions. If the potential of connected cells is not balanced, the charging and discharging of cells in the pack will be affected, bringing up the issue of cells that are out of balance due to inherent and extrinsic factors. Using active and passive cell balancing techniques can solve this issue. The right cell balancing technique can shorten the battery pack's equalization time and enhance its ageing. This paper explains the parameters of a battery, the function of the BMS, and different cell balancing techniques for use in electric vehicle applications.

Abstract

This paper aims to construct an experimental system using the Arduino UNO microcontroller board to measure the electrical quantities and protect against surge circumstances in a single-phase power supply. The system utilized a voltage sensor and a current sensor, and data was transferred to a personal computer for graphical examination. The Root Mean Square (RMS) method was used to measure electrical values, and the system is allowed to decide whether to turn the load on or off based on the comparison of RMS voltage measurement to the lowest and maximum voltages. The Telemetry Viewer v0.5 software was used to create the monitoring interface, which monitored the system's RMS voltage, RMS current, active power, and trip signal.

Abstract

This paper discusses the importance of Wireless Power Transfer (WPT) in a rapidly changing world. The goal is to introduce new technologies that can transfer power without the hassle of connecting cords for every single work, making devices more portable with less wear and tear, and providing an uninterrupted supply of electricity in every region. Wireless Power Transfer plays a key role in bringing change to the usage of the latest or pre-existing technology with a lot of conveniences and within a short time. The paper sheds light on recent progress in Wireless Power Transfer techniques, wireless charging, new possibilities for the future in the field of Wireless Power Transfer, and the development of business merchandise. This technique has provided promising ways to overcome the energy restriction of conventionally transportable devices. The techniques of Wireless Power Transfer will provide a way of making the dream come true of supplying 24/7 electricity not only in cities but also in remote areas, which will help in the development of every village and town that is currently not in the mainstream. The paper provides a summary of Wireless Power Transfer techniques, major developments in technical fields, and the recent advancements in networking applications. It highlights the potential of Wireless Power Transfer to revolutionize the way to use technology and the benefits it can bring to individuals and countries.

Abstract

This review article presents an overview of the Static Synchronous Compensator (STATCOM) device, its working principle, and its application for improving the stability of wind farms. The article also highlights the importance of STATCOMs in enhancing the power quality of wind farms by improving voltage stability, reducing power fluctuations, and mitigating grid faults. Due to continuously fluctuating wind speeds and faults, the active power, reactive power, and terminal voltage are susceptible to continuous change, which applies to terminal voltage as well. When a STATCOM is connected to the grid, the active power, reactive power, and terminal voltage are maintained at the same level during the connection. This also contributes to an increase in the system's transient stability, which is an important consideration. The review further describes the modeling and control of STATCOMs, including the selection of appropriate control strategies for specific wind farm applications. Finally, the article concludes with a summary of the future research directions for the STATCOM device and its potential for integration into the smart grid.
