Develop an EIS system combining hardware and signal analysis for real-time diagnostics of multi-cell high-voltage battery systems.
ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY (EIS) PLATFORM FOR REAL-TIME MONITORING AND DIAGNOSTICS OF HIGH VOLTAGE BATTERY SYSTEMS
Partner Call open until: 12.2026
Project Start: 01.2027
The goal of this project is to develop a flexible Electrochemical Impedance Spectroscopy (EIS) platform that combines custom hardware and advanced signal analysis for battery monitoring and diagnostics across different system levels, from single cells to high voltage battery packs, during operation.
Current EIS solutions are typically limited to laboratory environments or single cell measurements. This project aims to overcome these limitations by developing a custom system capable of performing impedance measurements at battery pack level under operating conditions for monitoring degradation and remaining useful lifetime prediction.
Expected results
- Prototype of an EIS platform for battery packs with integration into battery management systems (BMS)
- Demonstration of impedance measurements during real operation.
- New methods for battery health estimation and fault detection based on EIS.
We are looking for partners from
- Industry (battery manufacturers, repair industry, automotive, energy storage)
- BMS and system integration
- Electronics and hardware development
SAL Cooperative Model
