Engineer - Battery Thermal Simulation

The Battery Thermal Simulation Engineer will be responsible to develop, maintain, and conduct high-voltage (HV) Li-Ion battery pack-level thermal and CFD analysis, develop battery pack thermal models based on test results, and provide technical advice to internal and external customers for the design optimization of HV automotive Li-Ion battery packs.

• Conduct battery pack thermal and CFD (computational fluid dynamics) analysis — running simulations on battery packs, modules, and electrical subsystems, verifying design concepts, and providing assessments and recommendations to mechanical, electrical, and hardware engineers.
• Develop and coordinate test and validation activities for verification and validation of battery cells, packs, modules, and thermal management systems, including test plan setup, test involvement, project scheduling, and result analyses.
• Analyze cell test data and develop equivalent circuit models (ECM) and life models; apply the resulting models for module- and pack-level simulations.
• Develop battery Simulink plant models and battery pack thermal models based on test results.
• Conduct cell-level thermal analysis and integrate it with electrochemical simulations.
• Provide requirements for improvements to advanced simulation activities, including CFD, thermal, structural, and multi-physics analysis.
• Contribute to the future development of software and hardware for simulation support.
• Interact with validation engineers to conduct root cause analysis and provide technical proposals and solutions to resolve engineering problems.
• Participate in benchmarking activities.
• Be solution-oriented and adept at creating contingency plans to meet deadlines and milestones.
• Perform any additional duties as assigned.

To perform the job successfully, an individual must be able to perform each essential duty satisfactorily.
