Electrical circuits with thermoelectric generators (teg) for power storage

Abstract

Thermoelectricity is the direct conversion of thermal energy to electricity (as in thermo-electric generators (TEG)). Although the efficiency of TEG is quite low (within a room temperature of 100°C, the efficiency is approximately 10%), but this technology is of interest to researchers around the world. One of the reasons is that the model of energy production has changed, sustainable energy plays a very important role in the present and the future. In many equipment and processes, the waste heat is an unwanted product. Therefore, the applications of TEG are of great interest for recycling the energy. However, how to use effectively the thermo-electric energy is not simple and itrequires multi-disciplinary research and  high-tech facility fabrication. Researchers all over the world have been stuying continuously on materials science and the best structure of TEGs. Studying the efficiency of power generation for TEG components, this work reports the results of the current and voltage measurement from the difference in the heat sources in 4 TEGs. The system used the TEG1-12610-5.1 thermocouple module to install a heat energy application circuit for power storage (with 3.7V Lithium battery) and was connected to a computer for data acquisition. The data of graphs confirm that TEG's power generation is very stable and can be applied to other electrical devices.
