ENERGY GENERATION FROM WASTE HEAT AND CHARGING THE BATTERY

Description

Abstract

A large amount of energy produced in automobiles, industries, and electronic systems is lost to the surroundings in the form of waste heat. Recovering and utilizing this wasted thermal energy can significantly improve overall system efficiency and contribute to sustainable energy generation. The project titled "Energy Generation from Waste Heat and Charging the Battery Using Thermoelectric Generator (TEG)" focuses on converting waste heat into useful electrical energy through thermoelectric technology. The proposed system employs Thermoelectric Generator (TEG) modules, which operate on the principle of the Seebeck Effect. When a temperature difference exists between the hot side and cold side of a TEG module, a voltage is generated. In this project, waste heat from sources such as vehicle exhaust systems, industrial machinery, engines, or other high-temperature equipment is utilized as the heat source. The cold side of the TEG is maintained at a lower temperature using heat sinks and cooling arrangements to maximize the temperature gradient and improve power generation efficiency. The electrical energy generated by the TEG modules is initially low and varies depending on the temperature difference. Therefore, a DC-DC boost converter and voltage regulation circuit are incorporated to stabilize and increase the generated voltage to a suitable level for battery charging. The regulated power is then stored in a rechargeable battery, enabling the harvested energy to be utilized for powering auxiliary devices, sensors, lighting systems, and other low-power electronic applications. This project demonstrates a practical and sustainable approach to waste heat recovery using thermoelectric generators. The implementation of TEG-based energy harvesting systems can contribute to reduced fuel consumption, lower operational costs, improved energy management, and decreased environmental impact. The results highlight the feasibility of using thermoelectric technology for battery charging applications and showcase its potential for future deployment in automotive, industrial, and renewable energy sectors.
