With this measurement technique, eg, battery cells, modules, and packs can be tested while under charge or discharge conditions to see the behavior and chemical processes when the battery is stressed. This is also known as online impedance spectroscopy or high-power electrochemical impedance spectroscopy when performed on higher voltage potential and charge currents in case of a battery of 1 or multiple C rates.<\/p>\r\n<p>\u00a0<\/p>\r\n<h3 class=\"wp-block-heading\">Modes of EIS Measurement<\/h3>\r\n<p>This electrochemical impedance spectroscopy technique generates current excitation of certain frequencies and measures the voltage response (galvanostatic mode). Alternatively, it generates voltage excitations and measures the current response (potentiostatic mode). The galvanostatic mode ensures that the SoC does not drift during the measurement and is, therefore, preferred for battery cells. With the voltage and current readings, the complex impedance can be calculated.<\/p>\r\n<p><img decoding=\"async\" class=\"alignnone wp-image-4614 size-full\" src=\"https:\/\/cnrood.com\/wp-content\/uploads\/2024\/11\/how-is-a-measurement-performed-in-impedance-spectrometry.png\" alt=\"\" width=\"934\" height=\"444\" \/><\/p>\r\n<p>\u00a0<\/p>\r\n<h3 class=\"wp-block-heading\">Implications of Phase Shift and Impedance<\/h3>\r\n<p>The time lag of the voltage response causes a phase delay of the voltage to the current excitation during the frequency measurement. This phase shift results in a complex impedance with a real and imaginary part. Impedance is only defined for linear systems. Nevertheless, it can be applied to a non-linear system as a battery if its impedance can be approximated as being linear and time-invariant (ie, Linear-Time-Invariant LTI condition), meaning that the complex impedance was linear and did not change over time during the measurement, or at least was very close to linear and did almost not change over time; this is usually the case when, eg, the requirements, among others, are met:<\/p>\r\n<ul class=\"wp-block-list\">\r\n<li>The temperature of the cell does not change too much during one measurement.<\/li>\r\n<li>The open-circuit voltage (OCV) does not change too much during one measurement.<\/li>\r\n<\/ul>\r\n<p>\u00a0<\/p>\r\n<h3 class=\"wp-block-heading\">Practical Challenges and Solutions<\/h3>\r\n<p>In reality, the temperature of a cell will change because of the charge or discharge current and the OCV is dependent on the State-of-Charge (SoC) and temperature. As they change, the change in OCV is unavoidable as well.<\/p>\r\n<p>However, accurate and repetitive measurements of SOC and cell temperature after each measurement can help to evaluate how much these changes interfere with the quality and accuracy of the impedance measurement.<\/p>\r\n<p>\u00a0<\/p>\r\n<h3 class=\"wp-block-heading\">Technical Considerations for Effective EIS<\/h3>\r\n<p>The amplitude of the current excitation should be low enough not to influence the behavior of the cell but large enough to provide a sufficient voltage response with respect to the signal-to-noise ratio (SNR) of the used data acquisition system. That means the DAQ system must have a very good SNR, to be able to measure the tiniest voltage response signals in the mV range. The frequencies of most interest for entire battery packs, for example, are between 10 mHz and 2kHz. However, for battery cells, fuel cell stacks, and electrolyzers, a common frequency range is 1 mHz to 10 kHz (sometimes up to 20 kHz). With, eg, 10 steps per decade as a sweep or multi-sine measurement.<\/p>\r\n<p>\u00a0<\/p>\r\n<h3 class=\"wp-block-heading\">Visualization of EIS Data<\/h3>\r\n<p>After measuring several frequencies, the complex impedance can be drawn in the characteristic Nyquist plot, in which -Zimg is plotted on the Y-axis over Zreal on the X-axis. Each point in this XY chart is the result of one frequency. Another common visualization is the Bode plot. The impedance is plotted with log frequency on the X-axis and both, the absolute value of the impedance and the phase shift on the Y-axis.<\/p>\r\n<div class=\"wp-block-spacer\" aria-hidden=\"true\">\u00a0<\/div>\r\n<figure class=\"wp-block-image size-large is-resized\"><a class=\"swipebox\" title=\"\" href=\"https:\/\/www.gantner-instruments.com\/wp-content\/uploads\/2024\/05\/bode-plot.png\" data-rel=\"lightbox-gallery-6eFxC3rb\" data-rl_title=\"\" data-rl_caption=\"\"><img decoding=\"async\" class=\"wp-image-83694 entered lazyloaded\" src=\"https:\/\/www.gantner-instruments.com\/wp-content\/uploads\/2024\/05\/bode-plot.png\" alt=\"\" width=\"800\" height=\"450\" data-lazy-srcset=\"https:\/\/www.gantner-instruments.com\/wp-content\/uploads\/2024\/05\/bode-plot.png 800w, https:\/\/www.gantner-instruments.com\/wp-content\/uploads\/2024\/05\/bode-plot-300x169.png 300w, https:\/\/www.gantner-instruments.com\/wp-content\/uploads\/2024\/05\/bode-plot-768x432.png 768w\" data-lazy-sizes=\"(max-width: 800px) 100vw, 800px\" data-lazy-src=\"https:\/\/www.gantner-instruments.com\/wp-content\/uploads\/2024\/05\/bode-plot.png\" data-ll-status=\"loaded\" \/><\/a><\/figure>\r\n<div class=\"wp-block-spacer\" aria-hidden=\"true\">\u00a0<\/div>\r\n<p>\u00a0<\/p>\r\n<h3 class=\"wp-block-heading\">Advanced Diagnostics through EIS<\/h3>\r\n<p><strong>Check for linearity<\/strong>: For quality checks, it is useful to plot the applied sinusoidal current signal on the X-axis and the voltage response signal on the Y-axis.

When the system is non-linear the response signal will contain harmonics of the excitation signal in its spectra. The amplitude and number of harmonics can be used to evaluate if this non-linearity causes the quality and accuracy of the impedance measurement. An easier-to-check parameter is the Total Harmonic Distortion (THD), which is an indicator of how much harmonics distort the signal. That means how much the harmonic content influences the fundamental frequency.<\/p>\r\n<p>\u00a0<\/p>\r\n<h3 class=\"wp-block-heading\">How to measure Impedance signals on a high electrical potential<\/h3>\r\n<ul class=\"wp-block-list\">\r\n<li>Current and voltage signals must be recorded synchronously and at a high electrical potential.<\/li>\r\n<li>Best signal quality thanks to new measuring card for EIS signals (Q.series<\/li>\r\n<\/ul>\r\n<p>\u00a0<\/p>\r\n<h3 class=\"wp-block-heading\">The All-in-one EIS Solution<\/h3>\r\n<p>Gantner Instruments&#039; all-in-one EIS solution meets the requirements of electrochemical impedance spectroscopy (EIS) through its robust design and advanced technical features.
