2. ABSTRACT Static wireless charging is becoming popular all over the world to charge the electric vehicle (EV Dynamic wireless charging is introduced to EVs to capitally increase their driving range and get rid of heavy batteries. Wireless charging needs two kinds of coils named the transmitter coil and the receiver coil. The receiver coil will collect power from the transmitter coil while going over it in the means of mutual induction. The variation of distance between two adjacent coils affects the wireless power transfer (WPT). The transfer power for 150 mm air gap is 3.74 kW and transfer efficiency are gained up to 92.4%.The charging time is around 1 hour and 39 minutes to fully charge its battery from 0 state for a 150mm air The gap for an EV with 6.1 kW power may take. Also, a charging lane is designed for dynamic charging. Then the power transfer is calculated from mutual inductance when the EV is driven on a charging lane. From the load power, it can be calculated how further an EV can go with this extra power .

3. OBJECTIVES WPT technology has numerous inherent advantages over conventional means of power transfer, thus has received much attention in the past decade It has been proposed to apply to a wide range of applications, ranging from low power biomedical implants electrical vehicle charger to railway vehicles with efficiency up to 95% or higher in some prototype systems. Magnetic WPT systems rely on magnetic field coupling to transfer electric power between two or more magnetically coupled coils across relatively large air gap.

4. Based on the policy guidance and technologies that spring up. This section is supposed to envision the future WEVC Nowadays, global EV inventories are expanding vigorously. Under the trend of industrial prosperity, two potential orientations in WEVC consist of how to guarantee a sustainable growth of EV ownership and how to allow full play of scalable development of EVs. Power electronic devices can benefit from advanced materials as well. For one thing, besides flux leakage, switching loss is another major source of energy waste in a WEVC system. Dispensed with manual operation, static WEVC can liberate the operators hands but fails to make charging sites more flexible. FUTURE OF SCOPE

5. METHODOLOGY This method of wireless charging of electric vehicle is done through  inductive power transfer Where wireless transmission of power is achieved by mutual induction of magnetic field between transmitter and receiver coil. The state of the battery is monitored using Battery Management system

6. EXISTING SYSTEM A prototype of the whole system, consisting of this system to charging a electric vehicle from charging station. In the case of battery swap, by using a combination of computer vision and wired communication, the station can identify the exact location of each battery module to be swapped. The results are analyzed and discussed in the paper. Such a validated model can be used to establish if and when it is more convenient to use a structure rather than two separate devices.

7. PROPOSED SYSTEM DESIGN AND IMPLEMENTATION OF THE SYSTEM Solar based mobile were designed. As advance wireless charger particularly for small load system was implemented recently. In this proposed system, we implement microcontroller based wireless power charging methodology in electric vehicles. This system consist of Arduino and Mosfet, inductive coils, vehicle prototype module, Power is transfer to the road having the inductance primary coil from 230v AC supply. Vehicle having the secondary coil .

8. Magnetic induction charging uses the energy exchange between two pads, one located on the ground and one underneath the vehicle. The charging transmitter coil (on the ground) is approximately 1m, while the receiving coil (on the car) is enclosed in a small device. In addition to the pad optionally mounted on the vehicle, the infrastructure consists of an induction charging station. A receiver (receiving coil) is placed on the vehicle, while several coils acting as transmitters are embedded in the road surface. The later is supplied with electrical energy.
