What is a battery pack?

Introduction to the assembly of battery packs and their inspection. The smallest unit of a battery is called a cell. The three common shapes of cells are cylindrical, prismatic, and pouch. The state in which the cells are connected is called a module, and the state in which the modules are connected is called a pack.

How to know if a battery pack is bad?

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.

How do engineers test a battery pack?

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.
