Innovative solutions for modern challenges
High Voltage Impedance Analysis
Electrochemical Impedance Spectroscopy (EIS) Impedance measurement of the entire HV-Battery or HV-Powernet up to 950V
Electrochemical Impedance Spectroscopy (EIS), a frequency-based stimulus-response technique, delivers deep insights into the internal behavior of high-energy systems, making it essential for early fault detection, degradation analysis, and state-of-health monitoring in batteries and fuel cells.
Unlike conventional equipment, HV BODE’s High Voltage EIS Test Systems are designed to meet the demands of modern e-mobility. They enable precise impedance and phase measurements on entire battery packs and BEV systems up to 950 V, currently unmatched in the market.
