3. ABSTRACT
As we all know charging electric cars is a key
point in boosting energy shift, many solutions
are encountered along with electric charging
stations. Wireless charging is one such
solution. Wireless car charging is an upgraded
version of smartphone charging with some
differences. This type of charging allows an
electric vehicle (EV) to charge automatically
without any cables. The creation and research
of wireless charging systems for electric
vehicles is the subject of this paper.

4. COMPONENTS
USED
1.ARDUINO NANO
2.RELAY
3.LCD
4.MOSFET
5.IR SENSOR
6.INDUCTION COIL
7.POWER SUPPLY

5. SOFTWARE
Arduino IDE
The open-source Arduino Software
(IDE) makes it easy to write code and
upload it to the board. This software
can be used with any Arduino board.

7. ARDUINO NANO
ATmega328P microcontroller comes with a
built-in bootloader, making it easier to flash the
board with your code. The power
microcontroller is of the 8-bit AVR (Audio/Video
Receiver) family.
Operating voltage signal of 5V.
Power supply through VIN or VCC can vary
between 7V and 12V.
 32KB CPU Flash memory was by 2KB used
by the Bootloader.
16MHz clock speed or crystal oscillator.
2KB SRAM memory.
1KB of EEPROM memory.
Arduino Nano Pinout has 30 pins. Eight
analog Pins,14 digital pins, 6 Power Pins, and
2 Reset Pins.
19mA Power supply consumption.
40mA DC per I/O pin.

8. RELAY
A relay is an electrically operated
switch. It consists of a set of input
terminals for a single or multiple
control signals, and a set of operating
contact terminals. The switch may
have any number of contacts in
multiple contact forms, such as make
contacts, break contacts, or
combinations thereof.

9. LCD DISPLAY
 Available in two modes Common Cathode
(CC) and Common Anode (CA)
 Available in many different sizes like
9.14mm,14.20mm,20.40mm,38.10mm,57.0
mm and 100mm (Commonly used/available
size is 14.20mm)
 Available colours: White, Blue, Red, Yellow
and Green (Res is commonly used)
 Low current operation
 Better, brighter and larger display than
conventional LCD displays.
 Current consumption : 30mA / segment
 Peak current : 70mA

10. MOSFET
This miraculous growth in speed was made
possible by a tiny device inside electronic
gadgets called a transistor. More specifically a
type of transistor called MOSFET. MOSFET is
an electrically driven switch, which allows and
prevents a flow of current, without any
mechanical moving parts.
The MOSFET stands for METAL OXIDE
SEMICONDUCTOR FIELD EFFECT
TRANSISTOR. In MOSFET, the MOS part is
related to the structure of the transistor, while
the FET part is related to how it works.

11. IR SENSOR
 5VDC Operating voltage
 I/O pins are 5V and 3.3V
compliant
 Range: Up to 20cm
 Adjustable Sensing range
 Built-in Ambient Light
Sensor
 20mA supply current

14. APPLICATIONS
• Wireless charging for AGV (Automated guided vehicle) is the technology of the future when it
comes to power vehicles. In addition to the development of smart algorithms, sophisticated
sensor technology and decentralized intelligence in AGVs, right up to swarming behavior, are
inductive chargers (wireless charging) the key to making solutions even more powerful and
enabling fully automated agv system processes.
• Wireless power for AMR (autonomous mobile robots) makes them even more powerful in the
future. From person-to-goods and goods-to-person to transport, manipulation and sorting
tasks – the factory of the future demands mobility and flexibility. Autonomous Mobile Robots
(AMR) and AGVs are suitable for many automation tasks in production and logistics.
• Automated tugger trains are considered the most economical and safest solution for the
cycle-controlled supply of production lines. Compared to other material handling vehicles
such as forklifts, an automated tugger train achieves enormous productivity increases.
• Our inductive rapid charging systems enable fully automatic intermediate charging of the
vehicle battery. Wireless charging thus sustainably increases the performance of automated
fulfilment and e-commerce applications.

15. ADVANTAGES
Convenience: charge
your phone anywhere,
anytime. No need to
untangle cords or find
the right connector,
plus less cords means
less clutter on the
desk.
Safety / Performance: less
cords mean less electrical
faults. Most wireless
chargers are smart which
means they can
automatically turn off once
devices are fully charged
to stop overheating.
Form factor:
innovative design
with multiple uses.
Wireless chargers
can be disguised as
vases or even
lamps.
Won’t overheat your
phone: when your
smartphone is fully
charged, the wireless
charger automatically
shuts off. This means
less energy, a safer
charge, and no
overheated battery.

16. CONCLUSION
The technology of wireless energy transfer for mobile
devices has proved to be a convenient way of
supplying power to the useful gadgets. Unlike the
traditional form of contact charging, which utilizes
cables and cords, the new system is completely
wireless and hands free. This has automatically freed
users from the burden of having to carry with them
numerous charging devices for their mobile
equipments, wherever they go.
Wireless technology is at the moment, part of our
lives. The development has not only replaced several
wires that are used in machines, but also it has the
ability of replacing internal wires in various electronic
devices. It implies few problems encountered while
cleaning the surrounding and no fear of electric
shock, which might be caused by naked wires.
