Over the past few years, rapid developments in the automotive electrification space have led to aggressive concept-to-product timelines. The speed of these advancements highlights the need to develop material screening testing methods, which simulate cell and module thermal runaway events at a fraction of the cost and time compared to traditional automotive validation methods. Due to the rate of recent industry innovation, OEM's and Tier suppliers may have to rely on historically developed guidelines to drive future advancement. While the historical guidelines have been proven for past designs, they may not be appropriate for current and future electrification applications within the rapidly changing auto industry. By correlating fundamental material science with proper understanding of safety requirements, this short talk will show examples for the development of successful screening tools that can be utilized in the battery safety space. It will examine a methodology for developing battery pack safety related materials using novel screening testing methods to simulate traditional OEM testing for streamlined product validation.

Takeaway

Attendees will take away an understanding and appreciation for the gaps between full pack validation and fundamental material testing completed during solution development. Specific examples and challenges will be highlighted in the area of battery safety testing.

Intended Audience

Target audience for the talk includes battery pack designers, system integrators and manufacturing engineers. Basic background in cell types (cylindrical, prismatic, pouch) and general architecture of battery packs along with basic testing knowledge would be helpful but not required.
