The present scenario is like that the need of the electrical energy is growing rapidly whereas the resource availability is lagging behind the load demand due to its extinction which leads to hinder our overall generation. It has been observed that the sustainable resources have great future potential to take lead to generate power and supply demand. In the present scenario there exists a few energy resources equivalent to fuel resource. So, there must be a technology to trap the waste and unutilized heat available in the atmosphere and utilize it into the form useful electrical energy. In the current situation, waste heat in the form of thermal energy is recovered and converted into conventional electrical energy. Today, 70% of produced energy in automobiles is wasted in form of heat by exhaust gases. The main outcome of this paper is to manage the waste heat is being generated in the vehicles efficiently, by introducing the concept of “Thermo Electric Generator” (TEG) which convert the waste heat produced inside the vehicles and Re-Generate in the form electric current and give it back to the “storage unit” due to “Seebeck effect” concept.

Industrial plants are excellent sources of waste heat and provide many opportunities for energy harvesting using thermo-electric principles. A thermoelectric generator (TEG) is utilized in this study for harvesting expended heat from various sources. The main challenge associated with this type of technology lies in the creation of a sufficient thermal gradient between the hot side and the cold side of the TEG device. This is necessary for the module to generate an appreciable quantity of electrical energy. The performance of the TEG generator is tested using different configurations, different heat sources and different cooling methods. Heat sources included electrically driven devices, gas, biomass and gel fuel. Expended heat from different sites within an industrial environment was also chosen for operating the TEG device. The power produced by the generator is sufficient to operate low power LED lights, a DC radio receiver and a cellular phone charger.

Electrical energy has become a part of all human beings, the claim for electricity has been very high in the current days and hence electricity generated by usual means is not plenty. Nowadays solar, wind and thermal power station are mostly used to generate electricity. But by using this more amount of space can be occupied, fuel cost is increasing day by day, and also power consumption rate is very high in commercial sectors. So avoid these problems by using Thermo Electric power Generator (TEG). It is in the form of peltier coolers and TE generators. TE generator produces electrical energy from waste heat. It works based on principle of SEEBECK effect. It is named after the Baltic German physicist Thomas Johann seebeck. This paper proposed an idea of Design and Hardware implementation of Portable Generator using TEG. Hardware model was implemented and tested

Te Modules

Thermoelectric (TE) modules are a thermo-element device that can harness the heat and convert it into electrical energy. As an electrical generator system, TE has several advantages i.e not noisy, easy maintenance, relatively small, lightweight and environmentally friendly because it does not produce pollution. In this paper, the research about the performance of TE modules that used for electric generator has been done. TE modules utilize low temperature waste-heat from a solar cell that simulated with a combination of a bulb and a collector plate. TE modules which tested are single and double modules, in which for double modules, connectivity Thermal-Series was used. Parameters of performance such as output power generated are determined by measuring the temperatures difference and the voltages difference at the test module as well as using several equations. The results show that the distance of heat source and load applied will greatly affect the performance of thermoelectric generator (TEG) modules. The results showed that the number of modules and loading will greatly affect the performance of TEG modules. The use of heat pipes generate a far greater power 4-6 times on the single TE Module (0.84 mW) than without heat pipe (0.14 mW), and a double TE modules that uses heat pipe will became 4 times larger (1.48mW) than without heat pipe (0.37mW).

Circuit Analogy

Currently, bio-medical and automotive industries use thermoelectric module to reproduce electrical energy from wasted heat energy. Thermoelectric generator (TEG) modeling and simulation will be hashed out further in this  paper to achieve improvement. Finite element method (FEM) model, circuit equivalent model and mathematical/computer model are various methods employed to model the thermo-electric generator. Analysis of FEM modeling requires a high tier of knowledge of an engineer in material engineering. The circuit equivalent model uses the electrical circuit analogy to describe heat transfer and electrical behavior in TEG. In this work, the mathematical derivation of circuit equivalent model is used in computer models by using Simulink (Matlab). The result of the computer model can be an alternative model for electrical or electronics engineers to improve TEG performance in the future.
