As a battery pack designer it is important to understand the cell in detail so that you can interface with it optimally. It is interesting to look at the Function of the Cell Can or Enclosure and to think about the relationship between the Mechanical, Electrical and Thermal design.
When you think about designing a battery pack for electric vehicles you think at cell, module, BMS and pack level. However, you need to also rapidly think in terms of: electrical, thermal, mechanical, control and safety. Looking at the problem from different angles will help to ensure you don’t miss a critical element.
