Abstract:

This project aims to develop wireless charging technologies and it is also intended to give a message that how useful the plug-less

battery car charging is by creating a proof of concept for inductive charging. Since charging of the battery is possible to be

demonstrated . This project is built using electronic circuitry to convert AC 230 V 50 Hz to AC 12 V high frequency. The output

is fed to a tuning coil formed as the primary winding of an air core transformer. The secondary coil generates a voltage of 12

volts. Thus, the transfer of power is done by the primary (sender) to the secondary, separated by a considerable distance (for

example 3 cm). Therefore, the transfer can be viewed as being sent by the Primary and receiving power to perform the load. In

addition, this technology can be used in a variety of applications, including wireless charging of cell phones, iPods, laptop

batteries, and propeller clocks. Also, because this type of charge is electrically isolated, the risk of electrical shock is much lower.

This concept is an emerging technology and in the future research is underway around the world, which can extend the distance of

power transmission.

Keywords: Arduino Uno, RF Module, EM Coil, Buzzer, Dc Motor etc.

I. INTRODUCTION

The Wireless Power Transfer and Charge Module can be used in commonly used electronic equipment for close wireless

charging or a power supply. It consists of a transmitter and receiver and a coil, it could serve as a replacement for the wireless

power supply with a stable output voltage of 5 V and a maximum output current of 600 mA. Its small size and insulation coil is

more suitable for use in wireless projects. This module uses an electromagnetic field to transfer electrical energy between a

transmitter circuit and a receiver circuit. An induction coil creates an alternating electromagnetic field from inside the transmitting

circuit powered by 12V. The second induction coil takes the energy from the electromagnetic field and converts it back into electric

current to the receiver circuit that emits 5V - 600mA. The wireless power transfer and charging module can be used in common

electronic equipment for near wireless charging or a power supply. . Consisting of a transmitter and receiver and a coil, it could

serve as a replacement for the wireless power supply with a stable output voltage of 5V and a maximum output current of 600mA.

II. LITERATURE REVIEW

A SURVEY ON USER ACCEPTANCE OFWIRELESS ELECTRIC VEHICLE CHARGING Author:-Daniel Fett , Axel

Ensslen , Patrick Jochem and Wolf Fichtner This study presents the results of a survey-based analysis of user acceptance of

wireless technology.

Charging electric vehicles. A structural equation model based on the Davis technology acceptance model (TAM) is developed.

The integration of elements of Ajzen's planned behavior theory (TPB) is extended. The main factors that influence the acceptance

of wireless charging of the electric vehicle are evaluated and analyzed. The empirical findings indicate that the acceptance of the

participants of the survey on wireless charging of the electric vehicle is influenced mainly by affective assessments of wireless

charging, subjective norms, perceived utility of wireless charging and environmental awareness. The results indicate a high

degree of acceptance for wireless charging. Even people with a lower degree of acceptance are willing to use wireless charging

within fleets of shared or commercial vehicles.

REVIEW ON CONTACTLESS POWER TRANSFER FOR ELECTRIC VEHICLE CHARGING Author:-Ravikiran Vaka

and Ritesh Kumar Keshri For the past few years the feasibility of contactless power transfer (CPT) is being explored extensively

as a future solution for charging electric vehicles (EVs).

Studies report that the main obstacles in the CPT are low power efficiency, misalignment tolerance, cost, range and load

anxiety. This document presents a review based on the existing literature of CPT systems for EV loading. Different cases of CPT

technologies, their principle of operation and their equivalent analysis based on circuits are carried out. A discussion about

compensation strategies and their effectiveness are reviewed and discussed. The design of coil systems for some electric cars in

the city has been referenced in general. In the end, recommendations and conclusions are made based on the study and analysis of

the information available in the literature.

RF MODULE

Radio frequency (RF) is a frequency or rate of oscillation within the range of about 3 Hz to 300 GHz. This range corresponds to

frequency of alternating current electrical signals used to produce and detect radio waves. Since most of this range is beyond the

vibration rate that most mechanical systems can respond to, RF usually refers to oscillations in electrical circuits or

electromagnetic radiation

5. RESULT

6. CONCLUSION

The equivalent input impedance of rectifier load is mainly affected by system load resistance and rectifier input inductance;

rectifier load equivalent inductance will impact system performances, and should be considered for compensation network

design; the proposed load estimation methods have good accuracy, but still need to be improved in further research; the

proposed rectifier load calculation method and system load estimation methods all have good robustness on conditions of WCS

parameter variations. Although the works in this paper are conducted based on the specific system, they can be extended to

more applications, such as wireless charging systems with other rectifier or compensation network topologies, etc. They will be

helpful for system design and control to make EV wireless charging systems achieve stable operation and high performance.
