Let us now consider the battery performance parameters one after the other. Nominal Voltage (V). This is the rated voltage of the battery, specified by the manufacturer (rather than determined by anyone else). It is not only inscribed on the battery but also featured on the specification sheet.
These criteria are essential for a number of reasons: Selection and Sizing: Engineers can select the best battery for a certain application by knowing the parameters and calculating the size and number of batteries required to match the specifications.
The accuracy of the developed performance model was evaluated by computing the coefficient of determination R2 which was obtained by comparing the measured and estimated battery’s voltage profiles, according to Equation (8).
Three typical benchmark methods are introduced and validated on a commercial Li-ion battery. The effect of SOC, C-rate and current direction on parameters variation are discussed. The performance of the three methods is validated on HPPC and three different cycles.
Based on this novel parameterization procedure, the performance model of the studied Li-ion battery is developed and its accuracy is successfully verified (maximum error lower than 5% and a mean error below 8.5 mV) for various load profiles (including a real application profile), thus validating the proposed seven-step characterization methodology.
The secret to improving performance and prolonging the lifespan of battery systems may lie in understanding how these variables interact and vary over time. The term "capacity," which is used to refer to a battery's ability to hold and distribute electrical charge, is indicated by the letter "C".
