اطلاعات بیشترBattery 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.
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.
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.
An inherent part of battery testing includes charge and discharge tests to measure the battery capacity and the DC internal resistance at different state of charges (SoC). A battery is charged by using a source to put energy into the battery or discharged by using a load to draw energy out. Let’s consider a one-time-use battery as an example.
This resource gives you insight into various aspects of Lithium-ion Battery (LiB) pack evaluations.
