Energy Storage System (ESS) Intern (Summer)

REGENT•North Kingstown, RI

About The Position

REGENT's Energy Storage System team is working on how to store and deliver energy safely and efficiently for its Seagliders. The ESS Intern will support hands-on testing, battery characterization, and simulation work across the Squire and Viceroy programs. The role focuses on understanding how individual cells and full battery packs behave under real conditions, how they should be integrated into the platforms, and how to design the high-voltage vehicle architecture.

Requirements

Currently a senior or graduate student in mechanical, electrical, aerospace, or chemical engineering.
Knowledge of lithium-ion battery fundamentals, including capacity, C-rate, state of charge, internal resistance, voltage curves, and series/parallel configurations.
Proficiency in Python or MATLAB for data analysis and modeling.
Comfort building energy budgets and trade studies in Excel.
Self-directed and able to make progress on loosely defined problems.
Able to communicate findings and tradeoffs clearly and usefully to engineers.
Collaborative, adaptable, and comfortable working in a fast-paced startup environment.

Nice To Haves

Familiarity with a 3D CAD tool such as SolidWorks, Fusion, or Creo, and ability to produce clear drawings.
Exposure to battery-pack design, including cell selection, BMS architecture, busbars, or thermal management.
Exposure to battery simulation tools such as PyBaMM, Simulink/Simscape Battery, or COMSOL.

Responsibilities

Run tests on battery packs to characterize their performance under conditions Seagliders encounter, and report findings to inform the evaluation of energy storage options.
Support Paladin test operations, including test activities and battery servicing, while maintaining accurate testing documentation.
Use Python or MATLAB to simulate battery performance across different mission profiles.
Document battery-system integration into REGENT's high-voltage architecture across platforms.
Build and refine energy budgets and Excel trade studies comparing options across cost, performance, and integration complexity.
Track battery-pack-specific characteristics during testing, with attention to performance and safety.
