Interconnection of the battery cells creates an electrical and mechanical connection, which can be realised by means of different joining technologies. The adaption of different joining technologies greatly influences the central characteristics of the battery pack in terms of battery performance, capacity and lifetime.
LIB packs can be divided into four key components- including the cathode, anode, electrolyte, and separators. Understanding the thermophysical properties of battery pack components is fundamental for optimizing battery performance and avoiding catastrophic thermal runaway events.
An interdisciplinary approach for battery pack manufacturing is necessary due to the inherent multiphysical nature of the application to satisfy an increasing demand for electric cars.
Further challenges, he adds, are encountered as the battery system enclosure interacts with more of the chassis and vehicle system elements, such as seating anchors in the Tesla Model Y, for example. The structural impact of the cell-to-chassis approach is much greater.
“When you have a standalone battery pack bolted into a chassis, typically you will end up with the mounting structure being relatively close to the extremity of the vehicle, and it therefore comes into the impact fairly early.
The structural battery pack in Tesla’s Model Y can be seen as an example of the cell-to-chassis philosophy because, as the name suggests, the pack is a key load bearing member of the vehicle’s chassis, and it can be configured with or without modules.
