1 Cell Selection & Module Configuration Design

Cell Selection and Module Configuration is an early design stage where critical decisions are made that shape the entire battery module. It begins with rigorous cell selection, involving the evaluation and choice of the most suitable cell format (e.g., pouch, prismatic, cylindrical) and chemistry (e.g., NMC, LFP, NCA) based on the target application's specific demands for performance (energy density, power density, cycle life, safety), cost, and availability. 

Once a cell or cells are identified, the next crucial step is determining the optimal electrical configuration. This involves deciding how many cells will be connected in series to achieve the required module voltage, and how many cells (or series strings) will be connected in parallel to meet the desired module capacity and deliver the necessary power and energy. This series-parallel arrangement directly influences the module's overall dimensions, weight, thermal management needs, and the complexity of the Battery Management System (BMS). These initial choices profoundly impact all subsequent design and manufacturing aspects of the module.
