dc.titleDevelopment of a Thermal Dummy Cell (TDC) for Pouch Cells in Lithium-Ion Battery Thermal Management Systems
dc.typeThesis
dcterms.abstractLithium-ion (Li-ion) batteries have become indispensable in various sectors, including consumer electronics, automotive, and renewable energy storage, due to their high energy density, long service life, and efficiency. Effective thermal management is crucial to ensure the safety, performance, and longevity of these batteries. This thesis focuses on developing a segmented Thermal Dummy Cell (TDC) specifically for pouch cells—a novel and pioneering design that has never been constructed before. Unlike cylindrical and prismatic cells, which have been extensively studied, pouch cells have lacked sufficient research in thermal management, leaving a critical gap in the literature. Previous studies have developed TDCs for cylindrical and prismatic cells, providing valuable insights into the thermal behavior of these battery types. However, this research introduces the first-ever segmented TDC tailored for pouch cells, featuring independent control over each heating segment. This allows for precise temperature management that closely simulates real-world battery conditions. The system incorporates Pulse Width Modulation (PWM) control and advanced data monitoring, capturing essential parameters such as temperature, current, voltage, and power in real time. The thesis begins with a comprehensive review of existing literature on TDCs for cylindrical and prismatic cells, identifying the methodologies and findings that can be applied to pouch cells. It then details the iterative design process of the pouch cell TDC, including the challenges encountered and the solutions implemented. The final prototype consists of 11 heating pads arranged in a 3x3 grid for the body and 2 additional pads for the tabs, controlled via Arduino and PWM to achieve precise temperature control. Extensive calibration and testing were conducted to ensure the TDC accurately mimics the thermal behavior of real pouch cells. The results demonstrate that the TDC provides a reliable and safe means of studying thermal management strategies for pouch cells. By enabling individual control of heating segments, the system offers in-depth insights into localized thermal effects, making it ideal for research aimed at improving battery safety and efficiency. This development enables safer and more accurate studies of thermal behavior without the risks associated with live cells. This research represents a significant advancement in the field of battery thermal management by offering a novel tool for researchers and engineers. It serves as a key step forward in understanding and controlling the complex thermal dynamics of lithium-ion batteries, ultimately contributing to the evolution of energy storage technologies.
