Supriyadi and Edi Rakhman. Demonstrate the effect of wire diameter (AWG) and a number of turns used is directly
proportional to the amount of power that can be transferred. When the number of windings increases, more the
power will be transferred. When we use the enameled copper wire of 0.5mm diameter and keep the number of turns
to 26, and apply the input frequency of 470KHz. The power efficiency obtained at a distance of 1 cm is about 1.51%.
This result can turn on 1 Watt LED lamp.
N. UthayaBanu and U.Arunkumar. This study representing the various technologies related to Wireless Power
Transfer System, which is used to avoid the flux leakage during the transmission of power and to operate the cars
with high efficiency and improve the quality parameters. This project also shows the progress of generating power
source through renewable energy.
Govind Yatnalkar and Husnu Narman. Present a survey of Duration of Charging of Electric Vehicles is limited.
Therefore, wireless charging is important for Electric Vehicles in order to overcome the charging duration problem.
This paper also provides a current scenario of the art in electric vehicle wireless charging and the parameters that
require for charging section. The most important parameters for electric vehicle wireless charging are the distance
between the transmission and reception coils, the position of the coils placed on Electric Vehicle, battery sizes, and
the time for charging

7. Balamurugan A and Aman Bhattad. Propose a method to design an RFID based transaction system. This paper shows
how PIC Microcontroller board is interfaced with the RFID controller shield using the libraries developed for SPI
protocol. An RFID integrated campus ID card is scanned to the RFID reader in order to do the transaction and will
not be interrupted until the previous payment is complete and the card is swiped again for a new transaction. So, a
smart campus payment system is developed using the RFID controller shield.
Norsuzila Ya’acob and AzitaLaily Yusoff. propose a method of a cashless system that helpthe students at school level
so they can use LF RFID technology and database system. Generally, this Cashless Payment Transaction is designed
to replace the use of actual cash with virtual cash and parents can monitor their spending through the transaction data
that has been uploaded to the database every time whenever a transaction took place. The system also calculates the
remaining credit left inside the card and sent a notification to their parents. Once a credit has been transferred by
parents, students can continue to do other transaction.

10. .
Reduced infrastructure costs.
High power transfer efficiency.
Possibility of high-speed charging (but increasing costs).
Low maintenance requirements.
Provides higher reliability as the charging systems are operated automatically without dependence on
people to plug, unplug, and operate.

11. •Drive electronics and coils used in the charging device increase the complexity and cost.
•Due to the slower charging and lower efficiency, the devices take longer to charge with the same
supplied power.
•Electric car can travel less distance.
•If BMS (Battery Management System) fails this system cannot charge the vehicle..

13. •For using a non-conventional source of energy as a form of fuel to run a vehicle.
•To provide service at a reasonable price.
•To provide service at any place at any time.
•Battery is to charged by solar power stored in battery (DC to AC convertion is needed) should be given
to vehicle.
