Wireless Charging
Project Abstract / Summary :
WIRELESS CHARGING
Inductive charging (also known as "wireless charging") uses an Electromagnetic Field to transfer energy between two objects. 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 typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical Transformer - Wikipedia. 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 advanced materials for the receiver coil made of Silver plated Copper or sometimes Aluminium to minimize weight and decrease Resistance due to the Skin Effect.
.
For example, the Magne Charge vehicle recharger system employs high-frequency induction to deliver high power at an efficiency of 86% (6.6 kW power delivery from a 7.68 kW power draw).
Our Thinking About Disadvantage :
1: Induction charging cannot work on distant objects.
2: If we put a coin on the induction charger then the coin get start heating this can be dangerous.
3: Canât use mobile for longer time at the time of charging.
Solution :
1: We can use Magnetic Resoance in Induction charging to get the more efficiency of the Induction.
2: Overheating is not possible (Our assumption 98%).
3: Mobile can be use at the time of charging.
Why did you choose to work on this project topic : I have one more idea about GPS but that is not possible at my current Level.this Wireless Charging is my additional Project but it is also that much interesting as GPS. And contributing anything to the world even a pinch efforts makes anyone proud!!

- Protected connections â no Corrosion when the electronics are all enclosed, away from water or oxygen in the atmosphere.
- Safer for medical implants â for embedded medical devices, allows recharging/powering through the skin rather than having wires penetrate the skin, which would increase the risk of infection.
- Durability â Without the need to constantly plug and unplug the device, there is significantly less wear and tear on the socket of the device and the attaching cable.
- No e-waste
- Non -radiative energy transfer
- Lower efficiency, waste heat â The main disadvantages of inductive charging are its lower efficiency and increased resistive heating in comparison to direct contact. Implementations using lower frequencies or older drive technologies charge more slowly and generate heat within most portable electronic.
- Slower charging â due to the lower efficiency, devices can take longer to charge when supplied power is the same amount.
- More expensive â Inductive charging also requires drive electronics and coils in both device and charger, increasing the complexity and cost of manufacturing.
