Battery module and pack testing involves very little testing of the internal chemical reactions of the individual cells. Module and pack tests typically evaluate the overall battery performance, safety, battery management systems (BMS), cooling systems, and internal heating characteristics.
The final purpose of evaluating the battery pack consistency is to obtain its energy storage and power output capacity, that is, the maximum available energy Emax when the battery is fully charged and Pmax at a specific SOC point.
Key fundamentals of battery testing include understanding key terms such as state of charge (SOC); the battery management system (BMS) which has important functions including communication, safety and protection; and battery cycling (charge and discharge) which is the core of most tests.
First, the capacity of each cell in the battery pack Qi, the difference in remaining chargeable capacity of each cell when the battery pack reaches the charge cutoff condition Qdi, and the internal resistance of each cell Ri are determined to accurately characterize the battery pack consistency.
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.
