“…As can be seen from the figure, it has been used to drive miscellaneous devices, ranging from satellites to tiny biomedical devices. [31][32][33][34][35][36][37][38][39] An imperative feature of this harvester is that it consistently harnesses energy from a range of heat sources, such as human body heat, heat exchangers, automobile radiators, solar radiation, radioactive isotopes (generates heat from the natural radioactive decay of plutonium-238), and transforms them into electrical energy without requiring any moving elements and maintenance, which makes it more reliable. A TEG is a solid-state device that converts thermal energy (i.e., temperature gradient, ΔT) into electric potential through Seebeck effect phenomenon.…”

Energy harvesters (EHs) are widely used to transform ambient energy sources into electrical energy, and have tremendous potential to power wearables electronics and biomedical devices by eliminating, or at least increasing, the battery life. Nevertheless, the use of EHs for a specific application depends on various aspects including the form of energy source, the structural configuration of the device, and the properties of materials. This paper presents a comprehensive review of the classification of EHs, notably thermoelectric generators (TEGs), triboelectric nanogenerators (TENGs), and piezoelectric generators (PEGs) that allows a wide variety of devices to be operated. The EHs are discussed in terms of their operating principles, optimization factors, state‐of‐the‐art materials, and device structure, that directly influence their operational efficiency. Besides, the breakthrough performance of each of the EHs listed above is highlighted. From the review and analysis, the maximum output power density of 9.2 mW cm−2, 50 mW cm−2, and 64.9 µW cm−2, respectively, are obtained from the TEG, TENG, and PEG, respectively. Furthermore, recent applications relevant to a specific EH and their output performance, are also enlightened. Eventually, the essential outcomes and future direction from this review are discussed and encapsulated.

“…On the other hand, the work of [7] studied the state of charge estimation for the battery of satellites, but the authors did not assess it considering typical transient irradiance and temperature profiles found in orbit. There are also papers in the literature concerning specifically the design and management of satellites' power systems (electrical models) [20][21][22][23][24][25]; however, they do not present any generalized method that CubeSat engineers can further develop in order to satisfy the mission constraints and requirements that they are focused on in that moment.…”

An Integrated Thermal-Electrical Model for Simulations of Battery Behavior in CubeSats

This work presents an integrated thermal-electrical simulation model, capable of taking into account the thermal and electrical effects of the battery and photovoltaic panels for each instant of time in a given orbit and attitude. Using the physical equations that govern the thermal and electrical models involved during a CubeSat operation, the proposed integrated model can estimate the temperature and energy conditions of the battery, not only in an isolated way but also in considering the mutual effects on the system. Besides, special attention is given to photovoltaic panels used in the energy harvesting process, whose performance is affected by irradiance and temperature along the orbit. The integrated model can be useful for engineers when developing the subsystems of their CubeSats, taking into account, for example, the battery temperature control through a heater. Simulations were performed to illustrate the functioning of the proposed model with variations in the power requirements of its modules and the temperature of the battery throughout the orbit, and a heater’s influence on it.

“…For example, Liu et al [12] designed a radioisotope TE generator that meets the needs of low-power power supplies for deep space explorer and introduced the relationship between the output performance and the structure size, the heat source power of the TEGs. Ostrufk et al [13] introduced a solar TE generator applied to CubeSat and the generation capacity is analyzed for different positioning configurations of the TE generator relative to each CubeSat surface. Lamba et al [14] established the theoretical model of centralized solar TEGs, and analyzed the influence of solar concentration, input current, thermocouple number and load resistivity on the output power, energy and exergy efficiency of the power generation system.…”

Based on thermoelectric generators (TEGs), an aerodynamic heat energy recovery system for vehicle is proposed. A mathematical model describing the energy conversion law of the system is established, and the integrated calculation method which combined aerodynamic heating and thermoelectric (TE) conversion is given. Furthermore, the influences of the typical flight Mach number, flight altitudes and the length of TE legs on the energy conversion behavior of energy recovery systems are investigated. The performance of the energy recovery system is analyzed and evaluated. The results show that, the decrease of flight altitude and the increase of Mach number will obviously improve the performance of the heat energy recovery system with TEGs. The increase of leg length will increase the temperature of the hot end of TEGs and reduce the heat absorbed at the hot end. When the external load, Mach number and flight altitude is fixed, there exists an optimal length of legs corresponding to the maximum output power and maximum conversion efficiency of the system. The results will have significant positive impact on thermal protection and management of supersonic/hypersonic vehicles.
