FM Global is one of the world's largest commercial and industrial property insurance and risk management organizations, specializing in property protection. More than one out of every three Fortune 1000 companies, as well as leading international corporations, benefit from FM Global's superior financial strength, policy coverage, risk management skills and extensive expertise in loss prevention engineering and research. Ranked 447 on the FORTUNE 500 list of America's largest companies, FM Global employs more than 5,800 employees, including 1,900 loss prevention engineers in over 60 countries worldwide. FM Global's mission is to do everything they can to understand the client's business needs, reduce their risk, and be there before, during, and after a loss as an ally in resilience.
The Battery Testing Intern will work with Electrochemical Impedance spectroscopy (EIS) testing of small form factor Li-ion batteries. Develop tools to analyze EIS test results.
Electrochemical Impedance Spectroscopy (EIS) is a very powerful, fast and non-intrusive method to gain information about electrochemical systems, for e.g., batteries and battery packs. EIS is a swept frequency technique for evaluating the internal electrochemical and electrical properties of a battery under test. This method characterizes the impedance of a battery by stimulating it with a small amplitude AC signal. Sweeping the stimulus AC signal frequency provides a plot of the battery's response revealing a composite view of the battery's internal properties including interconnections, deterioration of plates, electrodes, or electrolyte.
The intern would be required to study the EIS test equipment and details about conducting the test. He/she would develop a method to automate the data extraction from the test equipment. This would included developing a program (MATLAB or python) to translate EIS test data to equivalent circuit using established models (circuit components to include SOH and internal impedance). Additional program capabilities would be needed to generate data displays, including multiple plots to facilitate detailed comparisons.
Graduate student pursuing MS/Phd majoring in electrical engineering.
Proficiency in MATLAB and/or python is required.
Experience in conducting lab experiments is preferred.
Internship period: 4 months, full time, onsite. (Some flexibility possible to adjust student's needs).
Please note that all FM Global visitors, including external candidates interviewing for open positions will be required to be vaccinated and should be prepared to provide proof of vaccination.
