Fire protection design concepts in a composite battery module housing

Automotive batteries are making significant strides towards power-dense designs. The development of the housing presents challenges of being lightweight while also ensuring enhanced safety in the event of thermal runaway of the cells. The presented battery study illustrates the methodical development of a module housing concept. By focusing on the advantageous use of composite material technologies, fire protection concepts can be directly integrated into the overall system. Furthermore, the development of the pouch-cell module aimed to simplify the assembly and the integration of a direct tab cooling. The cell pressure preload is also further integrated into the housing. The concept is methodically developed from a blank slate and elaborated upon until it reaches the prototype stage.
