“…In addition to all these, very different exhaust temperatures are obtained due to the structural features of motor vehicles and the variability in working conditions. For this reason, some di culties are encountered in designing and optimizing thermoelectric generators on the exhaust systems of motor vehicles (Zhu et al, 2022). The location and design of thermoelectric generators on the hot side of thermoelectric generators are very important to obtain high electrical energy from waste heat (Luo et al, 2022).…”

This study is aimed to design electrical energy production and wireless data monitoring system by utilizing the working principles of thermoelectric generators from the exhaust waste heat of vehicles in tra c. In order to transmit the heat transfer in the exhaust pipe to the thermoelectric generators, a modular system has been developed in a hexagonal form that can be dismounted and mounted from aluminum material. Six thermoelectric generators (TEG-SP1848) are used on the aluminum module, and a heat sink is used to cool each thermoelectric generator. The voltage and current values of the electrical energy produced from the exhaust waste heat of the vehicle in real driving conditions are recorded with a special program written on the card on the system. Depending on the results obtained from the test drives, electrical energy was obtained at a maximum voltage of 9.8 V and a current of 0.32 A. This electrical energy obtained from the exhaust waste heat can be stored in the vehicle's existing battery if desired. In this way, since the alternator used for the electricity generation of the vehicle will be activated less, some fuel savings will be achieved in the engine, and harmful exhaust emissions will be reduced. In addition, the electrical energy obtained by this method can be stored in an external battery independent of the vehicle battery and used for various purposes when the vehicle is at a standstill or with a portable battery.

According to the established model of a single resonance energy selective electron refrigerator with heat leakage in the previous literature, this paper performs multi-objective optimization with finite-time thermodynamic theory and NSGA-II algorithm. Cooling load (R¯), coefficient of performance (ε), ecological function (ECO¯), and figure of merit (χ¯) of the ESER are taken as objective functions. Energy boundary (E′/kB) and resonance width (ΔE/kB) are regarded as optimization variables and their optimal intervals are obtained. The optimal solutions of quadru-, tri-, bi-, and single-objective optimizations are obtained by selecting the minimum deviation indices with three approaches of TOPSIS, LINMAP, and Shannon Entropy; the smaller the value of deviation index, the better the result. The results show that values of E′/kB and ΔE/kB are closely related to the values of the four optimization objectives; selecting the appropriate values of the system can design the system for optimal performance. The deviation indices are 0.0812 with LINMAP and TOPSIS approaches for four-objective optimization (ECO¯−R¯−ε−χ¯), while the deviation indices are 0.1085, 0.8455, 0.1865, and 0.1780 for four single-objective optimizations of maximum ECO¯, R¯, ε, and χ¯, respectively. Compared with single-objective optimization, four-objective optimization can better take different optimization objectives into account by choosing appropriate decision-making approaches. The optimal values of E′/kB and ΔE/kB range mainly from 12 to 13, and 1.5 to 2.5, respectively, for the four-objective optimization.
