Battery Pack Development and Cost

This course covers the comprehensive process of battery pack development and cost, with a particular focus on electric vehicles. It starts with the transition from individual cells to a complete battery pack, discussing the importance of cell behavior, cell balancing, safety, thermal design, and the role of the battery management system. The course then delves into the electrical aspects of battery pack design, including the process of connecting cells in series and parallel, the impact of cell imbalance on battery life, and the significance of accurate State of Charge (SOC) and State of Health (SOH) estimation. The course also covers different battery charging techniques, the impact of temperature during charging and discharging, and the influence of these factors on battery life cycles and cost. Finally, the course concludes with a detailed analysis of battery costs for electric vehicles and the fundamentals of battery pack design, using the example of a small battery pack to illustrate the assembly and components involved in its creation.
