Optimizing Portable Power Banks: An Innovative Hybrid Energy Harvesting System for Efficient Energy Generation

With the increasing demand for portable electronic devices, there is a growing need for efficient and reliable power sources. Portable power banks have become popular solutions for on-the-go charging, but they often face limitations in terms of their energy capacity and recharging options. To address these challenges, this study proposes an innovative hybrid energy harvesting system for portable power banks. The proposed system leverages a combination of multiple energy harvesting technologies to maximize energy generation and ensure continuous power supply. It integrates solar panels, battery source, and kinetic energy harvesters into a compact and portable design. By harnessing energy from ambient light, and mechanical vibrations, the power bank can efficiently convert these sources into electrical energy. To optimize the energy harvesting process, the system incorporates advanced power management and control algorithms. These algorithms intelligently manage the energy flow between the different harvesting modules, ensuring the most efficient utilization of available energy sources. Additionally, the power bank is equipped with a smart charging system that adapts to various devices, providing the appropriate voltage and current levels for efficient charging. The performance of the hybrid energy harvesting system was evaluated through extensive testing under various environmental conditions. The results demonstrate its effectiveness in generating substantial amounts of power for extended charging capabilities. Compared to traditional power banks relying solely on a single energy source, the proposed system offers increased energy efficiency and longer operating times. Furthermore, the compact and portable design of the hybrid energy harvesting system makes it ideal for outdoor and remote applications where traditional power sources are limited. Users can rely on the power bank to charge their devices even in off-grid scenarios, making it a reliable and sustainable solution.
