Summary: The study developed a comprehensive electro-thermal model for cylindrical lithium-ion cells, showing that increasing the number of tabs connecting the jellyroll to the base can reduce internal thermal gradient by up to 25.41%. Side cooling was found to be more effective than base cooling at removing heat, with both methods resulting in similar thermal gradients within the cell. The modeling framework created is an essential tool for energy storage system design.

Summary: Managing temperature of lithium-ion cells in battery packs is crucial for their safe operation. Traditional cell datasheets lack sufficient thermal information to determine thermal management capability. This study introduces the Cell Cooling Coefficient (CCC) as a metric for defining thermal dissipation from a cell when rejecting its own heat. The study successfully defines and measures the CCC for cylindrical cells under base cooling, and evaluates the CCCBase of LG M50T (21700) and Samsung 30Q (18650).

Summary: This research uses a combined cooling method for the thermal management of lithium-ion batteries, combining flow boiling cooling via half-helical tubes wrapped around batteries with air-cooling method via air flow passing through the batteries. Numerical modeling was conducted using control volume technique, and the Eulerian-Eulerian multiphase model was used to model the flow boiling region. The results showed that the combined cooling method significantly improved thermal management of the battery pack, with flow boiling inside the helical tubes contributing to efficient heat removal and maintaining nearly constant battery temperature.

Summary: The battery thermal management system (BTMS) is crucial for the security and performance of lithium-ion batteries (LIBs). Liquid-based technique, as a major category of BTMS, has been extensively analyzed and reviewed due to its high heat transfer efficiency and thermal stability. However, the multi-objective optimization process and unified evaluation system for liquid-based BTMS have not been well refined and summarized. This paper systematically summarizes and analyzes existing liquid-based systems, provides a general framework for multi-objective optimization methodology, and constructs a unified and comprehensive evaluation system for various liquid-cooled BTMS.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
