Wireless Charging Using Solar Power Bank

The proposed project develops an Integration of solar power bank along with wireless charging acts as an alternative and offers nature and user-friendly method for charging mobiles. In the present digital world usage of portable devices is increasing and nature friendly solutions for charging is also increasing. Power banks depending on wired connections and grid electricity is not convenient in off grid or remote locations. The requirement of cables and external power sources is eliminated in this project since it uses both wireless charging with renewable energy source. The project shows concerns about energy efficiency environmental effects and portability. Solar power is used as renewable energy source along with mobile charging module and array of LED lights. Solar panel DC-DC converter is used for this project. Wireless transmission of power is ensured by using resonant inductive coupling. With this concept physical connections are eliminated and transfer of power can be done for a distance of approximately 25 to 30cm is possible. In resonant inductive coupling primary coil is placed near the converter and secondary coil is placed near the load. The design will incorporate efficient solar panels, a rechargeable battery management system, and wireless charging circuitry in a compact and durable enclosure.
