CAR team receives NSF funding for battery aging research

Posted: 

Engineers at The Ohio State University Center for Automotive Research received a three-year $250,000 grant from the National Science Foundation (NSF) for research to help understand how aging affects complex engineered systems consisting of many interconnected components. Researchers will demonstrate their methodology by developing tools to predict the life and current state of battery pack systems in plug-in hybrid electric vehicles.

Giorgio Rizzoni, director of the Center for Automotive Research, is the principal investigator of the project, which is sponsored by the NSF’s National Science Foundation Grants Opportunities for Academic Liaison with Industry Program. 

The first goal of the research is to understand how knowledge of the aging behavior of individual components, in this case battery cells, translates into overall system aging. Researchers aim to develop a systematic approach to assess the state of health of the system based on knowledge of its components states of health.

The resulting approaches will be demonstrated using a plug-in hybrid electric vehicle battery pack as a case study, in collaboration with General Motors. Deliverables include: mathematical models and computer simulations of aging propagation in a battery pack; the experimental validation of the life prediction methods, in collaboration with General Motors; graduate course materials; and an industry short course.

In addition to Rizzoni, the research team includes Simona Onori, research scientist at Center for Automotive Research, Andrea Cordoba Arenas, a mechanical engineering graduate fellow, and Yueyun Lu, an electrical and computer engineering graduate fellow.

The NSF Grant Opportunities for Academic Liaison with Industry (GOALI) Program aims to synergize university/industry partnerships by making funds of fellowships/traineeships available to support these linkages.
