Electrochemical impedance spectroscopy (EIS) stands at the forefront of advancing battery diagnostics, offering unparalleled insights into state of charge (SOC), state of health (SOH), and thermal runaway detection among other critical parameters for electric vehicle (EV) batteries and various energy storage systems. Our innovation introduces a groundbreaking chip-level EIS solution, engineered to deliver laboratory-grade EIS measurements directly within the operational environment of EVs and other battery-powered systems. This pioneering approach not only democratizes high-precision EIS analysis by embedding a miniaturized potentiostat within individual battery cells but also does so in a cost-effective manner. To benchmark its performance, our chip was tested on a large 230 Ah battery with 300 micro-Ohm zero crossing, against a commercial Gamry potentiostat. The findings affirm the chip-level EIS solution’s capability to match, and in some cases surpass, traditional laboratory equipment in noise rejection and sensitivity. Leveraging real-time, in situ EIS measurements, our solution empowers Battery Management Systems (BMS) with data-driven insights. Through the application of sophisticated physics-based and equivalent circuit models, it facilitates enhanced decision-making processes that can significantly extend battery cycle life, elevate safety standards, and optimize charging protocols. This presentation describes the transformative potential of our chip-level EIS technology in redefining battery diagnostics and management, setting a new benchmark for efficiency, and integration potentiostat capabilities in the realm of electric vehicles and beyond.

Student poster awards

Up to three posters are presented at this event. The first three (3) students to contact about presenting their work receive $100 and one year of free access to ECS Detroit Section events.
