This role is categorized as hybrid. This means the successful candidate is expected to report to Pontiac, Michigan three times per week, at minimum. In this role, you'll contribute to GM's vision of a Zero Emission future by supporting the thermal performance and integration of electric drive systems. You'll work with key components such as motors, inverters, and high-voltage connection systems to ensure optimal thermal behavior and system-level efficiency. You'll be responsible for developing accurate 1-D thermal models of electric drive components, integrating those models into broader system simulations, and creating software calibrations that enable seamless incorporation of thermal models into vehicle control systems across GM's electric vehicle portfolio. This position plays a vital role in advancing the performance, reliability, and efficiency of GM's next-generation electric vehicles.
Responsibilities
Develop and release 1D electric drive component thermal models
Perform thermal simulations of electric drives to determine thermal capability against component requirements and to support early architecture decisions
Represent electric drive component thermal analysis in larger system level thermal design activities
Verify model predictions against test data and continuously improve modeling capabilities through model correlation activities
Work with CAE teams to perform advanced thermal and flow simulations to ensure 1-D models are aligned with higher fidelity CAE models in areas of critical interest
Calibrate motor and inverter temperature estimation algorithms for use in vehicle control software utilizing component, subsystem, and vehicle level test data as well as analytical tools
Review and support both vehicle and component level testing
Compile and present simulation results to internal customers
Stay abreast of new technologies and competitive methods and products
Travel as required (less than 10%), both domestic and international
Requirements
BS in mechanical or electrical engineering or equivalent field
