Job description

Senior Battery Cell Modeling Scientist - Simulation

Responsibilities

Responsible for building cell mathematical simulation models (physical models and data-driven models) to predict the performance of Li-ion batteries/Li-metal batteries under various working conditions, including dynamic performance, lifetime decay, electrochemical and thermal response, and safety-related cell behavior

Design and advance experiments to obtain parameters/data required to build cell models

Work with cross-functional teams to develop, deploy, test, and maintain models

The electrochemical/thermal data of the cell under different working conditions are generated by using the certified physical model of the cell to provide data support for the establishment of the data-driven model

Establish a standardized process for cell physical modeling to reduce the resources/time required for modeling

  • Provide documentation related to model and algorithm development

Work with the battery team to determine and achieve battery performance life goals

Qualifications

Master’s degree or above, more than 5 years of battery related research/work experience

Basic knowledge of cell electrochemistry (P2D), thermal, mechanical modeling and simulation. Familiar with electrochemical principle, simulation parameter measurement method and corresponding equipment

Familiar with various battery-related models/algorithms, and have experience in using cell model software (COMSOL, Ansys, PyBaMM, etc.)

Experience in building data-driven models (statistical analysis, machine learning, AI)

Proficient in code development tools, such as Python or Matlab
