FM Research Physical Systems Resilience and Reliability Summer 2026 Internship or Co-op - Battery non-destructive testing

Join our team for a hands-on summer internship or summer/fall co-op focused on advancing next generation diagnostic techniques for Li ion cells and battery packs. This role is ideal for a graduate-level electrical engineering student excited about applying theory to real systems, building test setups, analyzing complex data, and contributing to cutting-edge research in battery health monitoring. Expected time frame is: 3-month Internship and/or 6-month Co-op. This is a full time, onsite role located in Norwood, MA.

Internship Objective

You will support a series of cell and pack cycling tests and evaluate the effectiveness of nondestructive diagnostic methods such as pulse testing and Rapid-EIS (Electrochemical Impedance Spectroscopy). This internship offers deep exposure to electrical engineering principles, data analysis, and experimental lab work while working directly with advanced battery cyclers and modeling tools.

What You'll Work On (Project Details)

As an FM Research Intern or Co-op, you will:

• Learn the operation of battery cyclers and program them according to detailed test plans.
• Conduct periodic nondestructive tests on Li ion cells to assess State of Power (SoP) and State of Health (SoH).
• Program cyclers to run pulse testing on cells/packs.
• Perform equivalent circuit modeling and interpret model parameters.
• Process and translate test data into established battery equivalent circuit models.
• Support the development and refinement of test setups and experimental procedures.

• Graduate student pursuing MS or PhD in Electrical Engineering.
• Strong proficiency in MATLAB and Python.
• Knowledge of equivalent circuit modeling and data analysis.
• Experience with instrumentation, control systems, and hands-on lab experimentation.
• Ability to develop test setups and execute structured test plans.

Preferred:

• Prior exposure to battery test equipment or EIS techniques.
• Familiarity with battery health metrics and electrochemical principles.
