Safety Framework for Mitigation of Fire and Explosion Hazards for Li-ion ESS

Session: Rapid-Fire Introductions by Poster PresentersDate: Wednesday, October 16, 2019 / 8:50AM - 9:20AM PDTTags: Poster / Deployment and Field Experience

This presentation will detail an experimental and modeling framework that is applied to evaluating thermal propagation, fire and explosion hazards  in battery modules and battery racks. In this framework, small scale abuse tests of single and multi-cell tests are conducted and various open-source computational modeling tools are used to evaluate safety metrics and predict safety performance. Results include predictions of thermal propagation and thermal runaway dynamics in multi-cell batteries and design considerations for deflagration venting. Large scale burn testing of 5 kWh is conducted to validate the the safety framework.

Attendees will gain a better understanding of how to effectively address and reduce safety risks of fire and explosions posed by Li-ion ESS.  Attendees will also be introduced to open-source tools that can be used to evaluate safety metrics and design safety and mitigation systems. These tools can be used to evaluate and develop emergency response protocols for ESS operators.
