Job description

The global objective of the Ph.D thesis is to develop a methodology to experimentally characterize and calibrate a model coupling aging phenomena and thermal gradient inside a battery. Eventually, this model will be implemented in a complete multi-physical model at module/pack level. The work is divided into several milestones:

§  Literature review

  • Lithium-ion battery modeling
  • Lithium-ion battery multi-physical behavior
  • Battery cooling systems and components

§  Development of the test set-up

  • Identify, design and optimize thermal management systems relevant to the issue
  • Experimental characterization and validation of the selected test set-ups

§   Battery testing

  • Battery aging tests at cell level for model calibration
  • Battery aging tests at cell and module level for model validation

§  Aging model development and application

  • Calibrate aging model at cell level with thermal-electrical coupling
  • Develop aging model at module level with multi-physical coupling
  • Model validation and application to real case scenario


  • Training/experience in energetics and thermodynamics is mandatory
  • Training/experience in electrochemistry and Li-ion battery is a plus
  • Deep interest in R&D and in battery electric vehicles application
  • Scientific open-mindedness and ability to work in a cross-disciplinary environment
  • Autonomous, innovative and proactive
  • Analysis, synthesis and communication skills

Starting date: early 2024 (possibility of fixed-term contract before the starting date)

Duration: 3 years
