3. INTRODUCTION
Solar Power Bank with WirelessCharging
Power banks are one of the need to have product these days. But even power
banks need charging. For that one needs to get the power bank charged in a
power plug.
This is not always possible when travelling so here we design a smart solar
powered folding power bank.
The solar power bank integrates solar charging with efficient battery support
and wireless charging to provide a multi functional unique power bank
product. The device is able to self charge anywhere during day time so that
he user never runs out of power.
The smart solar power bank integrates lithium battery pack with solar panels
battery protection and wireless charging coils using dc power boosters and
charge controllers to provide for a feature packed power bank.
This solar panels are used with charge controllers to charge the battery pack
using charging circuitry. The powerbank makes use of LED for indication of
current battery capacity. AN Adapter can also be used to directly charge the
powerbank using AC power ifneeded.
The battery pack power is used to power the induction coil that is mounted
on the top of the power bank. When mobile phone is placed over the top of
the power bank an electromagnetic induction effect induces electric current
in the coil mounted in the phone back. This is used to charge the phone
wirelessly.

Abstract
Key words : Power banks are one of the need to have product these days.
But even power banks need charging. For that one needs to get the power
bank charged in a power plug.
This is not always possible when travelling so here we design a smart solar
powered folding power bank.

6. The solar power bank integrates solar charging with efficient battery support
and wireless charging to provide a multi functional unique power bank
product. The device is able to self charge anywhere during day time so that
he user never runs out of power.

8. TECHNICAL FESIBILITY
There are 2 main things to consider choosing a Solar panelor
creating a Solarsystem. Battery capacity is measured in Amp Hours. The AH
figure must be multipliedby the battery voltage to convert this to Watt
Hours which is given by the simple calculationbelow. here are 2 main things
to consider choosing a Solar panelor creating a Solar system. Battery
capacity is measured in Amp Hours. The AH figure must be multipliedby the
battery voltage to convert this to Watt Hours which is given by the simple
calculationbelow. However, as we know that we will not be able to power
the battery once the voltage drops below our equipment’srequirements,
that is why, we are never really able to take all the power from a battery.
Lead acid batteries will give around 50% of their rated power and Li-ion
batteries will give around 80% of their rated power.
When the solar panelsare open, then sunlight direct falls on the
photovoltaiccell of the panel and it converts the solarenergy to electrical
energy. The panel gives a voltage of 12v and the charge flows through the
relay to the battery if the voltage is appropriate and is equal to the valueset
by the microcontroller to the battery. There is also a LED which displaysthe
transfer of charge from the panelto the battery. When the battery is
charged perfectly up to its full capacity,which is shown by the 4 LEDs
connected to the battery through the microcontroller, the microcontroller
shows the percentage of charge present in the battery and then we can
connect a mobilephone at the end of the circuit. Here, we also attach a
relay circuit which checks the flow of voltage. If we get low or high voltage,
the relay switches off and the circuit becomes open. With the appropriate
charge, we can charge the mobile phone at the end of the circuit where we

9. can get an USB port and the phone will be charged by connecting to the
port.
After conducting the experiments, we concludedthat in order to operate
with high efficiency, we need to go through these selections:
