1. System-Level Battery Pack Model development & Simulation 

• Develop and maintain multi-domain battery pack models representing electrical, electrochemical and thermal behaviors as well as pack durability, swelling and cooling loop operation and control. 

• Define the appropriate model fidelity and simulation approach depending on project phase, use case, and required decision timeline. 

• Develop and operate workflows for trade-off studies, sensitivity analysis, design of experiments, surrogate model generation, and multi-objective optimization (safety constraints, integration constraints, mass, and cost-related drivers, …) 

• Assess implication of control strategy and BMS/BTMS algorithms on system operation and fault scenarios (MiL, SiL). 

• Run simulations for normal (usage profiles, testing, thermal) and fault conditions, including cooling loss scenarios, sensor failures or drift, electrical fault conditions, thermal excursions, and safety-relevant operational limit studies. 

• Model and workflow standardization, automation and documentation

2. Empirical & EC-Type Model Requirements, Development & Parameter Identification 

• Establish and own model requirements for equivalent circuit, thermal, ML, and other empirical/surrogate/reduced-order battery models for system simulation and control-oriented applications under normal and fault scenarios. 

• Support CAE engineers for the development, maintenance, and deployment of ECM/ROM/ML/surrogate models. 

• Coordinate model parameter identification with CAE, testing, and product validation engineers at the cell, module, and pack levels, including OCV and DCIR/ACIR, SOC/temperature dependencies, and aging-related parameter evolution.

• Maintain model assumptions and limitations, parameter traceability, model-change traceability, validation status, applicability domain, and release and usage guidelines. 

3. Multi-Physics Model Integration 

• Integrate domain knowledge into the battery pack system models and translate high-fidelity simulation inputs into fast and decision-oriented system models in close collaboration with CAE engineers. 

• Develop co-simulation workflows with integrated high-fidelity models through direct coupling or using FMI/FMUs. 

4. BMS/BTMS Algorithm Development & Control-Oriented Support 

• Develop advanced state estimation (SOC, SOH, SOX) algorithms, including KF, MHE, physics-based, and machine-learning approaches and incorporate/execute in system simulation workflows.
