Battery Pack and Module Testing Battery Module and Pack tests typically evaluate the battery performance, safety mechanisms, cooling systems, and internal heating characteristics. Engineers and scientists also measure the state of charge (SoC), depth of discharge (DoD), direct current internal resistance (DCIR), and state of health (SoH) as part of the characterization and validation process. Tests are also conducted to evaluate the electronic components and systems attached to the battery, such as the battery management systems (BMS), connected wires, sensors, and battery fuses. Tests performed at Module Level Module tests are performed to assess the quality and capacity of each cell integrated into the module. The process includes both charge and discharge tests to ensure the cell connections (in parallel or series) are secure and robust to manage the expected current loads without overheating, weakening, and failing. Additionally, other tests like thermal abuse, mechanical vibration, high-voltage protection, and environmental tests are carried out at this level to ensure voltages are accurate and safe, temperature sensors function effectively, and cells are well balanced. Tests performed at Pack Level Pack level testing is sometimes also called End-of-Line Testing or Assembly Testing. It is mainly performed to ensure that each pack subsystem performs efficiently, including external hardware, safety mechanisms, and BMS Battery management system communications. If the strings of modules within the pack show irregularities in the expected voltage, resistance or capacity range, it can be found here and rectified. Engineers also check for any malfunction, temperature rise in the battery pack, current carrying capacity, cooling capacity, and overall mechanical structure. After complete testing, packs may undergo extra testing to simulate the typical conditions and be integrated into the system or end-product.
