CAR team receives funding from National Science Foundation for battery aging research

Giorgio Rizzoni, director of the Center for Automotive Research, will be the principal investigator in a project sponsored by National Science Foundation Grants Opportunities for Academic Liaison with Industry (NSF GOALI). The project will be funded by NSF for three years, totaling $250k and will be supported by a partnership with General Motors. The aim is to develop a methodology to understand the propagation of aging in complex engineered systems consisting of many interconnected subsystems and components, and to demonstrate it by developing tools and methods to predict life and understand the state of health of battery pack systems in plug-in hybrid electric vehicles.

In addition to Rizzoni, the proposal was written by Simona Onori, research scientist at Center for Automotive Research, and mechanical engineering graduate fellow Andrea Cordoba Arenas. Also to work on the project is electrical and computer engineering graduate fellow Yueyun Lu.

The first goal of the research is to understand how knowledge of the aging behavior of individual components (e.g. battery cells) translates into overall system aging. The second goal is 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 are then 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 a short course designed for industrial audiences.

About the NSF GOALI program
Grant Opportunities for Academic Liaison with Industry (GOALI) promotes university-industry partnerships by making project funds or fellowships/traineeships available to support an eclectic mix of industry-university linkages. Special interest is focused on affording the opportunity for:

  • Faculty, postdoctoral fellows, and students to conduct research and gain experience in an industrial setting;
  • Industrial scientists and engineers to bring industry's perspective and integrative skills to academe; and
  • Interdisciplinary university-industry teams to conduct research projects.
