Summary: With the advancement of thermoelectric material properties, the thermoelectric generator has gained more attention in heat recovery. The design parameters significantly affect the performance of TE modules and systems. Interestingly, integrating more thermoelectric modules does not always lead to higher economic performance, output power, and energy efficiency. This study proposes a novel sizing method to find the optimal size parameters for both module and system levels. Through a case study on exhaust gas from a truck engine, the analytical results provide guidance for thermoelectric generator system designs and facilitate large-scale industrial applications.

Summary: The current design optimization efforts for thermoelectric modules focus on constant temperature difference, while the effects of constant heat flux on module output parameters are still unclear. A three-dimensional numerical model is established using COMSOL Multiphysics software to study PbTe as a case study. Heat transfer analysis verifies that the reduction in hot side temperature is dominated by the Peltier effect, leading to deviation in the optimal load resistance and internal resistance ratio from the traditional maximum power point. Increasing the thermoelectric leg height improves the average figure of merit zTavg and output performance. Manipulating the leg cross-sectional area ratio achieves a high efficiency of -14.5% for ideal contacted PbTe-based modules at a temperature difference of 500 K. The importance of parasitic energy loss on performance evolution is recognized. These findings provide universal guidance for improving the efficiency of thermoelectric modules operating under constant heat flux.

Summary: A three-dimensional numerical study was conducted to investigate the cooling performance of a thermoelectric module with multilayer pyramid thermoelectric legs. Two physical models, rectangular shaped and multilayer pyramid thermoelectric cooling modules, were compared. The study focused on the effect of leg height, side ratio, and the number of leg layers on the cooling performance. The results showed that the multilayer pyramid module had better cooling performance than the rectangular shaped module, with a maximum reduction of 11.25 K in the minimum averaged temperature of the cold surface. However, the cooling performance of the multilayer pyramid module was not very good when the values of side ratio and the number of leg layers were low. A recommended map for evaluating the cooling performance was presented based on the side ratio, the number of leg layers, and the heights of thermoelectric legs.

Summary: This study proposes a state-of-health (SOH) attenuation model considering driving mileage and seasonal temperature for battery health estimation, which is significant for battery pack management and maintenance. The variable forgetting factor recursive least square (VFFRLS) algorithm is used for battery model parameter identification and the extended Kalman-particle filter (EPF) algorithm is proposed for online capacity estimation. The proposed model and algorithm are verified using actual vehicle data over nine months. The experimental results demonstrate the accurate estimation of model parameters and capacity through the proposed algorithm, and the decrease in average capacity of the battery module with total mileage. The compensation of monthly driving mileage and ambient temperature factors effectively improves the accuracy of the SOH model.

Summary: This study selects organic fluid (R245fa) with low boiling temperature for phase change cooling of PEMFC stack and employs organic Rankine cycle (ORC) for waste heat recovery. The effect of channel layout, sectional size, and channel shape on cooling and heat recovery performance is investigated through simulation of boiling flow. The results demonstrate the good cooling performance of flow boiling, as the cooling plates can be cooled to a reasonable temperature with a maximum surface temperature difference within 15 K. The serpentine straight channel and spiral straight channel achieve the highest ORC thermal efficiency of 7%, while the serpentine zigzag channel has the best temperature uniformity contribution due to its secondary circulation flow. This study showcases the potential of flow boiling for PEMFC thermal management and provides guidance for cooling channel design.
