Battery Thermal Engineer

As a member of the Battery Modeling team, you will be responsible for Thermal modeling for all products. You will be fully integrated with the Product Design team from the earliest stages, analyzing and informing the design of cutting-edge products. You will also work with cross-functional teams within Apple to provide design guidance in terms of thermal impact of the product features.

• Develop of state of art Thermal as well as multi-physics finite Element (FE) models of cell, pack, and BMS sub-systems
• Provide deign and trade-off guidance to the PD teams through early stage simulations, particularly in cases such as fast charging and high power functions
• Generate models/capability to convert power map into thermal outputs
• Perform advanced Thermal/CFD simulations to evaluate and enhance understanding of the various boundary conditions at the cell, pack, BMS sub-systems around battery packs well as in system
• Work with test and reliability labs, to develop physical test methods, to gather necessary data for results validation
• Work with system teams, to collaborate on developing detailed sub-models to be used in assembly level simulations
• Develop optimized workflows and/or reusable templates for regularly required thermal simulations
• Work with CAE vendors to drive the functionality improvements to better serve the CAE needs of the group
• Explore new analysis types and solutions, including topological optimization
• Extract Reduced Order Models (ROM) from CFD simulations to speed up the exploratory studies

• BS degree in Mechanical or Electrical Engineering
• Experience with CFD and thermal modeling
• Master’s degree, PhD or equivalent job-related experience in Mechanical Engineering, Electrical Engineering or equivalent
• Familiarity with Ansys HFSS 3D Layout and SIWave
