Discover Infineon's advanced Electrochemical Impedance Spectroscopy (EIS) solution for battery management systems, demonstrated at Embedded World 2026!

Deepak Varma presents our comprehensive battery analysis system that provides real-time insights into battery aging, degradation, and safety parameters.

Key Features:
✅ 8-cell series battery monitoring with BMS IC
✅ AURIX TC3 microcontroller with FFT computation
✅ Smart Battery Pack Monitor (SPM 1.0) for current sensing
✅ ISO-UART daisy chain communication
✅ Passive excitation circuit with sinusoidal signal injection
✅ Real-time Nyquist plot analysis

What EIS Measures:
📊 State of Health (SOH) - via curve slope analysis
📊 State of Charge (SOC) - via curve width/height
📊 Thermal runaway parameters - via high-frequency measurements
