Abstract :
Accurately estimating the state of charge (SOC) and state of power (SOP) of the battery is essential for optimizing the use of electric quantity and ensuring the safe and efficient operation and energy management of the battery system of electric vehicles. In this paper, a particle swarm optimization algorithm is used to identify the model parameters of lithium-ion batteries under wide temperature range, and a SOC estimation method of adaptive cubature Kalman filter algorithm based on singular value decomposition (SVD-ACKF) is proposed. The Cholesky decomposition of covariance of state variables is replaced by singular value decomposition, which successfully avoids the problem of the non-positive definite matrix during the adaptive updating of the cubature Kalman filter algorithm, and improves the convergence stability of the iterative computation process. Based on accurate SOC estimation at each temperature, the key constraints in this study are composed of the combination of the SOC, voltage, and current of the battery, and changes in battery model parameters due to ambient temperature are considered, developing an SOP estimation strategy under multi-constraint conditions, realizing the joint estimation of SOC and SOP, verifying the feasibility of the proposed state estimation algorithm in different ambient temperatures. The results show that the maximum error of SOC estimation under different ambient temperatures is less than 0.015, and the SOC estimation error of the proposed method is the smallest compared with the extended Kalman filter (EKF) and the cubature Kalman filter (CKF), and the average relative errors of peak charge power and peak discharge power estimation with a duration of 30 s at 25 degrees C can be kept within 2.5% and 1.5%, respectively. It is proved that the proposed method has good accuracy and adaptability.

Abstract :
Lithium-ion battery disposal is becoming an increasingly important issue with the rapid growth of Electric Vehicles (EVs) regarding resource conservation and environmental sustainability. It is considered the most suitable solution to reuse rather than dispose of retired batteries. However, the precision in estimating the battery states is of great importance to ensure the operational safety and efficiency of reused battery packs. This study proposes a joint estimation method to predict the State of Charge (SOC) and the peak power capability for reused battery packs considering inconsistency. The primary content of this work is described as follows. (1) This paper designs an improved screening method for evaluating the consistency of the reused batteries that are used to connect to the series battery pack. (2) A second-order RC model is selected as the cell mean model (CMM) to represent the overall performance of the reused battery pack. On this basis, the mean SOC is estimated by using Sage-Husa adaptive algorithm and extended Kalman filter (SH-AEKF), whereas the peak power capability is evaluated by considering multiple limitations. (3) An experiment is conducted to evaluate the robustness of the joint estimation method. The results show that the maximum absolute error of SOC estimation is below +/- 3 % while the mean absolute percentage error (MAPE) of peak power capability estimation could be limited to less than 3.5 %. This study indicates the high accuracy and reliability of the proposed joint estimation method for retired battery packs.

Abstract :
Compressed air energy storage will have good development prospects because of its exceptional safety and reliability, low economic cost, zero carbon emissions, and pollution-free environmentally friendly characteristics, which meet the needs of sustainable and green development. In view of the problems of large volume, great number of equipment, and poor flexibility of traditional compressed air energy storage equipment, this article built a compressed air experimental bench based on pneumatic motor and conducted integrated pneumatic motor compression/expansion experiments. The effects of key parameters such as speed, torque and current on the performance of pneumatic motor under different modes are investigated, providing reference for the application and promotion of small compressed air energy storage systems. The results indicate that in the expansion mode of the pneumatic motor, the total efficiency and power output of the motor can reach up to 14.01 % and 1257.87 W. Its high power output and economic operation are concentrated within the medium range of rotation speed and current, respectively, with a certain cooling effect achieved in this mode. In compression mode, the maximum output power of the motor can reach 3696.33 W, while the energy efficiency is up to 78.39 %. The operating parameters such as torque and current are basically positively correlated with the system performance parameters. The integrated system is flexible, saves space, and has certain feasibility.

Abstract :
This paper proposed a single-piston free piston expander-linear generator (SFPE-LG) prototype applied to organic Rankine cycle systems. Two valve timing control strategies, namely, time control strategy (TCS) and position control strategy (PCS), were developed. Based on the experimental data, a back propagation neural network (BPNN) prediction model was established. The effects of structural parameters such as neural network layers, transfer function, training function, hidden layer nodes, and learning rate on the prediction accuracy of this BPNN model were discussed. The training and prediction accuracy of the BPNN model was verified using 5-fold cross-validation and Wilcoxon signed-rank test. Moreover, the BPNN model was integrated with a genetic algorithm to predict and optimize the maximum output power of the SFPE-LG. The results showed that the BPNN model used to predict the motion characteristics and output performance of the SFPE-LG exhibits strong learning ability and high prediction accuracy. Notably, the prediction accuracy of the BPNN model is significantly higher under the PCS compared to TCS. The effect of hidden layer nodes on mean square error (MSE) and correlation coefficient (R) is greater than that of the learning rate. When the number of hidden layer nodes exceeds 30, the BPNN model consistently achieves low MSE and high R. The optimization results showed that the SFPE-LG can obtain a maximum output power of 141.69 W under the TCS, when the working parameters are inlet pressure of 0.7 MPa, intake duration of 35 ms, load resistance of 67 omega, and expansion duration of 104 ms, respectively.

Abstract :
Solid oxide fuel cells (SOFCs) are an effective and sustainable energy conversion technology. As operating temperatures decrease, metal interconnects and supports are widely employed in SOFCs. It is critical to apply a protective coat on ferritic stainless steel (FSS) to suppress Cr evaporation and element interdiffusion under high temperatures. Electrophoretic deposition (EPD) is a promising approach for depositing metal oxides on FSS substrate. Here, a method based on 3D multi-physical simulation and orthogonal experimental design was proposed to optimize deposition parameters, including applied voltage, deposition time, and electrode distance. The EPD process to deposit Mn1.5Co1.5O4 particles in a suspension of ethanol and isopropanol was simulated and the effects of these three factors on the film thickness and uniformity were analyzed. The results indicate that applied voltage has the greatest impact on deposition thickness, followed by deposition time and electrode distance. Meanwhile, deposition time exhibits a more significant effect on film unevenness than applied voltage. Additionally, the particle-fluid coupling phenomenon was analyzed during the EPD process. In practice, these deposition parameters must be selected appropriately and the deposition time must be controlled to obtain a uniform coating. The proposed method can reduce cost and shorten the design period.

Abstract :
The organic Rankine cycle (ORC) system is an important technology for recovering energy from the waste heat of internal combustion engines, which is of significant importance for the improvement of fuel utilization. This study analyses the performance of vehicle ORC systems and proposes a rapid optimization method for enhancing vehicle ORC performance. This study constructed a numerical simulation model of an internal combustion engine-ORC waste heat recovery system based on GT-Suite software v2016. The impact of key operating parameters on the performance of two organic Rankine cycles: the simple organic Rankine cycle (SORC) and the recuperative organic Rankine cycle (RORC) was investigated. In order to facilitate real-time prediction and optimization of system performance, a data-driven rapid prediction model of the performance of the waste heat recovery system was constructed based on an artificial neural network. Meanwhile, the NSGA-II multi-objective algorithm was used to investigate the competitive relationship between different performance objective functions. Furthermore, the optimal operating parameters of the system were determined by utilizing the TOPSIS method. The results demonstrate that the highest thermal efficiencies of the SORC and RORC are 6.21% and 8.61%, respectively, the highest power outputs per unit heat transfer area (POPAs) are 6.98 kW/m2 and 8.99 kW/m2, respectively, the lowest unit electricity production costs (EPC) are 7.22 x 10-2 USD/kWh and 3.15 x 10-2 USD/kWh, respectively, and the lowest CO2 emissions are 2.85 ton CO2,eq and 3.11 ton CO2,eq, respectively. The optimization results show that the RORC exhibits superior thermodynamic and economic performance in comparison to the SORC, yet inferior environmental performance.

Abstract :
有机朗肯循环(ORC)是实现中低温热能高效利用的主要技术之一.选择适宜的工质和循环结构可以显著提高ORC的热力学性能.本文基于工质参数化模型提出一种ORC构型和工质的热力学评价方法.首先,通过建立的工质参数化模型实现了ORC工质物性参数和循环参数的协同优化,从而获得不同构型ORC在不同热源条件下的最高热效率,进而确定了ORC的最佳构型和最适热源温度.然后,分析了在最佳构型下优化得到的工质物性参数与实际工质之间的差异.最终,在优化得到的工质物性参数的基础上,通过建立多元线性回归模型实现了不同工质ORC热力学性能的准确预测.结果表明,回热式结构是ORC的最佳循环结构,其最佳热源温度为300℃;利用基于优化得到的工质物性参数建立的多元线性回归模型预测不同工质热力学性能时,相对误差范围为0.8% ~-1%.
