Manufacturers of commercial thermoelectric modules provide datasheets of the modules including information and graphs about the performance attained at several working conditions. Details about internal parameters are not made available to customers, because in the broad majority of the cases they are not necessary. However, when developing non-standard applications or conducting research projects it is sometimes necessary to make the modules work in different conditions than those shown in the performance curves. This paper shows a methodology to extract thermoelectric internal parameters from the information provided by performance curves, hence allowing scientists to predict the performance of the module at any working condition. The method is based on the basic equations that link thermal and electrical dynamics in which some parameters must be estimated. As a result it is possible to predict the behavior of the modules if they are operated in a non-standard way. One good example is to simulate how a module designed for cooling applications will behave if used as a Seebeck module for power generation. The proposed methodology has been successfully applied to a commercial Peltier module for which the behavior as a thermoelectric generator was simulated and then tested experimentally, attaining very similar results.

“…Waste heat recovery technology utilizes the waste heat from ICEs and provides valuable work in mechanical or electrical power. Vázquez et al [6] suggested that utilizing around 6% of engine exhaust heat would reduce fuel consumption by about 10%. Figure 1 shows a typical energy flow of an engine based on the fuel energy.…”

With the progress of modern times, automobile technology has become integral to human society. At the same time, the need for energy has also grown. In parallel, the total amount of waste energy that is liberated from different parts of the automobile has also increased. In this ever-increasing energy demand pool, future energy shortages and environmental pollution are the primary concerns. A thermoelectric generator (TEG) is a promising technology that utilizes waste heat and converts it into useful electrical power, which can reduce fuel consumption to a significant extent. This paper comprehensively reviews automobile thermoelectric generators and their technological advancements. The review begins by classifying different waste heat technologies and discussing the superiority of TEGs over the other existing technologies. Then, we demonstrate the basic concept of and advancements in new high-performance TEG materials. Following that, improvements and associated challenges with various aspects, such as the heat exchanger design, including metal foam, extended body, intermediate fluid and heat pipe, leg geometry design, segmentation, and multi-staging, are discussed extensively. Finally, the present study highlights research guidelines for TEG design, research gaps, and future directions for innovative works in automobile TEG technologies.

This article presents an effective method for harvesting waste heat from a household cooktop. The energy‐harvesting module contains a thermoelectric (TE) module, heat pipe module, and phase change material (PCM). The effects of TE modules, cooling mediums (air, water, and paraffin), and heat sink configuration and arrangement on the overall performance of the energy harvesting module are examined experimentally. It is found that the cooling process on the cold side of TE plays an essential role on the output voltage and system performance. By adding an air‐cooled heat sink, both output voltage and temperature difference can be moderately improved. Yet using a water‐cooled heat sink can improve the output voltage by about four times higher. Furthermore, the output voltage can be further promoted by using more efficient thermoelectric module. It appears that fewer fins incorporated with the PCM container filled with paraffin shows the optimal energy harvesting performance. Additionally, the recharging time for the full, medium, and low flame operation is tested with 3, 4, and 15 minutes, respectively, and the maximum recharging power of 7.25 W can be achieved with the highest energy storage of 523 mAh after operating 30 minutes.
