BACKGROUND
[002] Background description includes information that may be useful in understanding the
present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] A wireless charging device is designed for charging battery-powered devices without
providing any wired connections such that electrical charges are transferred wirelessly from
wireless charger to devices such as watches, mobile devices, gaming devices etc. The wireless
charging device can include three types of technique namely inductive charging, radio charging,
and resonance charging, wherein inductive charging uses electromagnetic field to transfer
electric charges from charging system to the devices such as toothbrushes, and watches, radio
charging uses radio waves for transferring energy to corresponding antenna configured in device
to enable charge small batteries, and resonance charging uses high frequency magnetic field to
charge large devices or equipment such as robots, electric cars, electric motorcycles etc.
[004] The devices are configured with rechargeable batteries include but not limited to
mobile phones, flashlights, laptops, palm-sized computers, shavers, gaming devices, radios,
tablets, power tools, and toothbrushes. The rechargeable batteries in the devices include lithium-
ion, nickel-metalhydride, or nickel-cadmium type, and lead-acid batteries configured with the
devices need to be recharged in a cyclical period to enable uninterrupted usage of the devices.
[005] In traditional wireless charging device, power plug is needed for continuous electric
supply to wireless charger for recharging the devices. In travelling, user finds very cumbersome to carry wireless charger, said user try to find enough sockets for the wireless charger to recharge the devices while travelling in a bus, train, personal vehicle etc. Furthermore, due to resistive heat and lower efficiency of wireless charger more time and electricity are consumed to recharge batteries.

[006] In prior art technique, wireless radio charging device includes transmitter as a laser
diode and receiver as photovoltaic cell. Energy is transferred from laser diode to receiver via light energy such that the receiver reconverts the light energy into kinetic energy. Main disadvantages of using wireless radio charging device is that it can recharge one device at a time, and require continuous electric supply for recharging batteries. Moreover, the wireless radio charging device generate excessive heat that leads to high energy losses, low efficiency, and act as a safety hazard to human health.
[007] There is, therefore, a need in the art to provide a wireless charging device that
overcomes the resistive heat, low efficiency, recharge single device at a time, and needs continuous electric supply of the existing solutions and utilize techniques, which are robust, accurate, fast, efficient, cost-effective and can recharge multiple devices at a time.
