“…Using the concept of the average double layer particularly the PbO 2 /electrolyte interphase. EIS is also widely used as a tool for estimation of the state of charge (SoC) and state of health (SoH) of the battery [2][3][4][5][6][7][8][9][10].…”

“…Among various techniques employed for the characterization of VRLA batteries, impedance studies are known to provide several important battery performance parameters, such as ohmic resistance, charge-transfer resistance, double-layer capacitance, etc. [25][26][27][28][29][30][31], which are seminal: (a) to derive information on optimum utilization of the batteries, (b) to identify battery failure mode, and (c) to determine the state-of-charge (SoC) 1 of the batteries. In general, an electrochemical cell comprises resistive, capacitive and inductive components.…”

Several commercial-grade hybrid-VRLA and AGM-VRLA cells and batteries have been assembled and tested under varying charge-discharge rates in a temperature range between 50 and −40 • C. Impedance studies on hybrid-VRLA and AGM-VRLA cells have been conducted to reflect on their resistive and capacitive values. A linear relationship is found to exist between logarithmic state-of-charge values and ohmic impedance of batteries. In general, hybrid-VRLA cells and batteries perform better than their AGM-VRLA counterpart. A field-performance study conducted on AGM-VRLA and hybrid-VRLA batteries for solar-lighting application also suggests the latter to be superior.

“…Nondestructive tests that require only current and voltage data include: full change/discharge cycling, pulse train, and Electrochemical Impedance Spectroscopy (EIS). In particular, EIS is influenced by SOC [19] and the shape of the impedance curve is often related to degradation mechanisms, such as gassing at a single electrode [20].…”
