Job DescriptionIn this position...
The Battery Cell Simulation Engineer is responsible for developing and applying advanced electrochemical models (P2D/P4D) to understand battery cell performance, degradation, and lifetime behavior, with direct linkage to system-level life prediction for Battery Energy Storage Systems (BESS).
This role builds physics-based cell models to quantify degradation mechanisms and translate them into system-level life simulation inputs, enabling accurate warranty estimation and augmentation strategies. The position acts as a key bridge between cell-level electrochemistry and BESS system performance, supporting data-driven decisions on durability, reliability, and lifecycle cost optimization.
ResponsibilitiesWhat you'll do...
- Electrochemical Modeling (Primary Focus)
- Develop and apply high-fidelity electrochemical models, including P2D/P4D lithium-ion battery models and reduced-order models for system integration.
- Simulate reaction kinetics and transport phenomena, lithium concentration gradients and overpotential, and internal current density and utilization distribution.
- Evaluate cell capability limits, including power and energy capability, SOC-dependent performance, and rate limitations under different conditions.
- Cell-Level Life & Degradation Modeling
- Develop physics-based models to predict cell degradation, including SEI growth and side reactions, lithium plating risk and conditions, and loss of active material and impedance growth.
- Quantify capacity fade and resistance increase over life, and sensitivity to temperature, SOC window, and cycling conditions.
- Support cell design trade-offs and degradation mitigation strategies.
- Thermal-Electrochemical Coupling
- Develop coupled electrochemical-thermal models, including heat generation from electrochemical reactions and temperature-dependent kinetics and degradation.
- Analyze cell temperature gradients and hot spots, and thermal impact on performance and aging.
- Provide heat generation and degradation sensitivity inputs for system-level modeling.
- Manufacturing Variation & Cell Behavior
- Incorporate manufacturing-induced variations into cell models, including electrode thickness and loading variation, porosity and density variation from calendaring, and microstructural heterogeneity.
- Evaluate impact of process variation on performance distribution, and manufacturing defects on degradation and life.
- Support translation of modeling insights into process control targets and cell consistency and quality improvements.
- System-Level Life Modeling Interface (BESS Integration)
- Translate cell-level model outputs into system-level inputs for BESS simulations, including degradation rates under varying duty cycles and temperature and usage sensitivities.
- Support development of system-level life prediction models and duty cycle-based aging simulations.
- Collaborate with system and CAE teams to ensure consistent model integration and proper scaling from cell to pack to system.
- Warranty Estimation & Augmentation Strategy Support
- Provide modeling inputs for warranty projections (capacity retention, degradation limits) and performance degradation over service life.
- Support evaluation of BESS augmentation strategies (e.g., module replacement, capacity add-back) and trade-offs between degradation, performance, and cost.
- Enable data-driven decisions on lifecycle management and total cost of ownership (TCO).
- Model Calibration & Validation
- Calibrate models using experimental data, including cycling and aging tests, and EIS, rate capability, and thermal data.
- Validate performance and degradation predictions vs. test data.
- Conduct sensitivity analysis, parameter estimation, and uncertainty quantification.
- Cross-Functional Collaboration
- Work closely with the Ford Battery Modeling Team and BESS system and controls teams.
- Support external suppliers with model alignment and parameterization.
- Translate detailed electrochemical insights into system-level engineering decisions.
QualificationsYou'll have...
- Bachelor's degree in Chemical Engineering, Mechanical Engineering, Materials Science, Physics, or related field.
- 3+ years (MS) or 5+ years (BS) of experience in battery modeling or related fields.
- Strong expertise in electrochemical modeling (P2D or equivalent) and lithium-ion battery fundamentals.
Even Better, you may have...
- Master's or PhD in relevant discipline.
- Experience with P2D/P4D electrochemical models and battery degradation and life modeling.
- Familiarity with system-level battery life modeling (BESS or EV) and warranty or lifecycle analysis.

- Degradation & Life Prediction - strong understanding of aging mechanisms and lifetime modeling.
- Cell-to-System Translation - ability to convert cell physics into system-level life predictions.
- Multiphysics Integration - electrochemical-thermal coupling capability.
- Analytical Problem Solving - identifies drivers of degradation and performance variation.
- Collaboration - works across cell, system, and CAE teams.
- Communication - translates complex models into actionable insights.
