Energy data acquisition system X-ion™ EIS

modularhigh-resolution

AVL X-ion™ EIS enables battery, electrolyzer, and fuel cell measurement that is both fast and reliable, based on the Electrochemical Impedance Spectroscopy. It can be combined with various AC excitation systems and offers a complete package of solutions, from the stimulus to a high-resolution measurement system for quantifying the response of the inner impedance of the UUT. At the heart of the system is AVL X-ion, a highly dynamic data acquisition unit. In combination with the AVL EIS software, the AVL X-ion EIS solution enables multichannel EIS and harmonics analysis for UUTs up to 1,200 V. Why You Need an EIS Measurement System The highly dynamic market transition towards electrification requires a closer look at the individual systems, focusing on battery and fuel cells. To improve their efficiency and lifetime, these components must be analyzed in detail. Finding errors at an early stage, observing degradation effects, and evaluating the state of health of battery and fuel cells are crucial tasks for a wide range of applications in all stages of development – from R&D to end-of-line tests. New measurement and evaluation methods like the Electrochemical Impedance Spectroscopy (EIS) provide this detailed information. Highly Accurate Measurement Results The modular structure of the X-ion EIS system enables the perfect fulfillment of a wide variety of requirements. The various possible combinations of AC sources and signal conditioning units allow everything to be covered – from pure Electrochemical Impedance Spectroscopy of PEM FC, batteries, and SOFC, to resonance frequency analysis and impedance spectroscopy of inverters or other DC bus components, for example.
