Job Summary

NREL's Transportation and Hydrogen Systems Center has a postdoctoral research position available. The selected candidate will be responsible for integrating NREL’s battery modeling framework into commercial battery simulation software and performing simulation-based analysis to investigate performance and safety of lithium-ion batteries for electric-drive vehicles as part of the DOE Vehicle Technologies Energy Storage program. The postdoctoral researcher will also support parameter identification and simulation validation by performing experiments. This position will support R&D conducted in-house and externally by NREL researchers and University and industry participants.

Job Duties

Job duties include, but not limited to:

  • Integrating NREL’s battery modeling framework into commercial battery simulation software and performing simulation-based analysis to investigate safety, performance, and life of lithium-ion batteries for electric-drive vehicles.

  • Work with NREL researchers to enhance NREL’s Multi-Scale Multi-Dimensional (MSMD) battery model bridging particle-, electrode-, cell-, and pack-scale physics

  • Integrate battery model into commercial computational fluid dynamics (CFD), chemical engineering and heat transfer codes

  • Improve safety of li-ion battery units with simulation-based analysis

  • Modify existing models to run using generalized solvers and design experiments and analyze data to validate model predictions

  • Perform component-level and cell-level safety testing and extract modeling parameters

  • Document work in detailed technical memos, laboratory notebooks, milestone reports, and journal articles and present at technical conferences
