Fig No.1 Block diagram of the wireless solar mobile charger. The proposed system as shown in Fig.1 consists of a solar panel that acts as a DC power source and is used to charge the battery. Battery discharge is a direct current signal. Wireless power transfers are based on the same presentation when the current conductor produces a magnetic field.
This smart approach extends battery life and improves device performance. The device utilizes the Basic MPPT P&O Algorithm to dynamically track the solar panel’s Maximum Power Point and optimize power extraction. The Lithium Battery Charging Characteristic Algorithm adjusts the charging levels to ensure safe and efficient charging.
The vulnerabilities of USB charging connectors and the increasing reliance on smart devices necessitate the development of portable wireless charging systems. By harnessing solar energy and incorporating advanced charging algorithms, the device offers a versatile and efficient charging solution.
By harnessing solar energy, it provides a sustainable and environmentally friendly alternative to traditional charging methods, particularly beneficial for users in areas with limited access to power sources.
