The document proposes a method for wirelessly charging batteries using microwaves. It notes that current wireless charging methods require devices to be placed on charging plates, which can be inconvenient while traveling. The proposed method would allow electronic devices to charge as they are being used through harnessing leftover microwave radiation from cellular networks. Charging would work on the same principle as a microwave oven, using microwaves to heat the batteries and provide power. This could both charge devices conveniently during use and reduce hazardous health effects from excess radiation.
Hi there,
Many of us forgot to charge their mobile phones and if there any powercut we can't charge the mobiles right ! . These problem is solved here... For more details download this ppt Now.

This project explains a simple wireless battery charger circuit that charges your mobile when placed near the transmitter.
This circuit may be used as wireless power transfer circuit, wireless mobile charger circuit, wireless battery charger circuit, etc.
A presentation on wireless charging.
Inductive charging (also known as wireless charging or cordless charging) uses an electromagnetic field to transfer energy between two objects through electromagnetic induction. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.
Induction chargers use an induction coil to create an alternating electromagnetic field from within a charging base, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electric current to charge the battery. The two induction coils in proximity combine to form an electrical transformer Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling.
Recent improvements to this resonant system include using a movable transmission coil (i.e. mounted on an elevating platform or arm) and the use of other materials for the receiver coil made of silver plated copper or sometimes aluminium to minimize weight and decrease resistance due to the skin effect.

This is our 3rd semester project of electronics-1 which is a mobile battery charger with night switch as load circuit, it will work as a ups the night switch works on input 220 volt supply and when we cut off the supply it continues it working on battery power and vice virsa.
Smartphones and multiple electronic gadgets have become a daily necessity for our life as we have created a huge interdependency on gadgets. Introduction of the electronic gadgets with multiple features have made our lifestyle easier and faster. Smartphones are the most importance and widely used electronic gadget and it can be observe that every new day brings a better innovation in its manufacturing. Along with the innovation In the smartphone, we need a major innovation in its charging methods. In the initial days of the mobile phone manufacturing, its chargers used to work on the constant current supply system. After few years the next generation chargers came with the constant voltage system and the next major update was the introduction of the constant current And constant voltage charging system, which was used for a larger period of time. When the competition in the field of innovation incremented massively, smartphone brands focused on making there smartphone charging rate faster than others and they started using the microcontrollers for increasing there charger’s output. There are multiple smartphone brands with there own different charging technologies like DASH, TURBO, VOOC etc. These charging technologies works on there full potential when connected to The devices which support those technology’s communication. When we connect these high power output chargers to the devices which doesn’t support its communication Style , the charger doesn’t supply the power with the full potential even if the device is capable of handling the load. There is a need for a charger which doesn’t have the compatibility issues with any kind of devices which require the power input between The range of power output supplied by the charger. There is the need for the charger with the wide range of power supply that can charge a earpiece to smartphone. In our Auto Power Adjustable charger’s proposed methodology , we are considering all the above parameters to create a universal charger, which can be used to charge any type of device in its output range. We will add an extra circuit which will be responsible for the feedback from the device’s battery for analysing the required power output . We will supply the exact amount of power which is required by the device and it will minimize the chances of the damage on the less powered batteries. The test results are showing the positive responses till the date . Arduino is the major component , which is responsible for the decision making in the regulation of the power output. Here we can conclude that our charger can eliminate the chances of the damage on the battery and it can supply the power output of a wide range.

ABSTRACT:
It is a hectic task to carry everywhere the charger of mobile phones or any
electronic gadget while travelling, or it is very cruel when your mobile phone getting off
by the time you urgently need it. It is the major problem in today’s electronic gadgets.
Though the world is leading with the developments in technology, but this technology is
still incomplete because of these limitations. Today’s world requires the complete
technology and for this purpose here we are proposing the wireless charging of batteries
using Microwaves.
Now in the recent days we come across some solutions for this problem by using
the Witricity (Wireless Transmission of Electricity). Recently Nokia has launched Nokia
Lumia 920 smart phones whose special feature is its wireless charging. But this is
possible only when the device is placed on to the plate given for the wireless charging. So
it is also somewhat difficult to travel with those charging plates. There may chance has
forgetting the charging plates, and then we require something which can charge our
electronic gadgets whenever they get used.
The proposed method gives the solution for this problem. Once think that how it
will be when your electronic gadget gets charged on using it? Then the label will come as
“CHARGE ON USE”. This wireless charging method works on the principle of
MICROWAVE OVEN. As the things when placed in microwave oven gets heated, in the
same way these batteries should work using microwaves which are the medium of
communication from long back. We are getting our network in terms of microwaves and
it is proved that the total radiation coming from the cellular mobile communication is not
been using and the remaining radiation is creating hazardous problem for human beings.
So here we are working on the concept that why can’t we use those remaining radiations
in order to charge our batteries? This will be the best solution to reduce the effect of
radiation.
