Battery Electric Safety Research IDIQ

This project is focused on safety of lithium-ion batteries for battery electric vehicles (BEV). Lithium-ion (Li-ion) batteries used in BEVs must meet a wide variety range of safety standards, including operation extreme conditions, including crash and flooding incidents.  These unpredictable and non-standard abuse conditions can result in a thermal runaway condition of the Li-ion battery pack.  Performer has significant expertise in experimental and modeling capabilities relevant to abuse and safety of lithium-ion batteries for electrified vehicles.  Collaboration with industry has also resulted in several tools being transitioned from the lab for commercial implementation.  Specific areas of battery focus include novel safety techniques, fail safe design and crash induced crush modeling.  Specific recent examples are a battery internal short circuit device, electrical isolation of defect cells, and mechanical-electrochemical-thermal models. The performer will evaluate the different Li-ion battery abuse scenarios and mitigation solutions by means of outreaching to subject matter experts (SMEs), testing, and simulation and will provide findings and recommendations.
