Solar Energy Conservation Using Wireless Sensor Network-Based Street Light Monitoring for Charging Hybrid Electric Vehicles

Abstract

The demand of the energy sector needs a hybrid energy storage system that will satisfy high energy and power demands for the eV field. As per Ragone's plot lithium-ion battery and supercapacitor, combination can be the best-suited approach to meet this demand reduce the stresses on the battery, and improve the life cycle as a single energy storage device. The short charging and discharging time of the supercapacitor, and the proposed hybridization can lead to failure. Here main theme of the work is to conserve solar and street light energy to store it in suitable energy storage devices located on the street poles so that an ample amount of charging facilities can be made available. The proposed system uses WSNs to monitor and control the performance of the street lights in real time and to reduce the wastage of energy. Combining solar panels with energy storage devices with proper control mechanisms, excess solar energy produced during daylight hours can be used later, especially at night when energy demand is higher. Intelligent monitoring systems adjust the intensity of street lights based on ambient light, traffic availability, and traffic conditions. Additionally, the system provides charging power for electric vehicles, using stored solar energy during off-peak hours. Wireless communication systems facilitate seamless communication between charging stations and WSNs, ensuring efficient resource allocation and preventing power grid overload. The proposed solution offers many advantages such as reduced dependence on conventional energy, lower operating costs, and a sustainable urban environment.
