The internal resistance of lithium-ion batteries is correlated with power density, energy efficiency and state of health (SoH), and dynamically changes with SOC, temperature, aging and other factors, with EIS as the core method for its complete impedance characterization. By applying small-signal AC excitation from mHz to kHz, detecting voltage/current response and analyzing complex impedance, it can correlate the internal physical phenomena of batteries, construct equivalent impedance models of passive components, and provide accurate basis for battery performance analysis.
The CT/CE-8000 series integrates EIS function, which seamlessly integrates with charge-discharge and cyclic voltammetry (CV) tests, enabling multi-dimensional analysis without moving the battery. With high stability and dynamic analysis capability, the device can accurately analyze battery impedance characteristics, help researchers construct equivalent circuit models, explore the correlation between impedance and internal electrochemical processes of batteries, and provide reliable electrochemical data support for performance optimization and health assessment of EV battery cells.
