Electrochemical impedance spectroscopy (EIS), a frequency-based stimulus-response technique, provides in-depth insights into the internal behavior of high-energy systems and is therefore indispensable for early fault detection, degradation analysis, and condition monitoring in batteries, fuel cells, and similar systems.

Unlike conventional devices, HV BODE’s high-voltage EIS test systems are specifically designed to meet the requirements of modern e-mobility. They enable precise impedance and phase measurements on entire battery packs and BEV systems up to 1,000 V—and that within a few minutes, which is currently unique on the market.
