Abstract
This research aims to investigate the adaptability of a measurement system or a process in determining the parameters of batteries. Methods are suggested for different applications, and properties gained by these measurements are specified. Deformations of lithium polymer batteries measured by various methodologies are also analyzed in detail. Changes in the geometry of worn-out batteries and the localization of the changes can be better understood by applying the results. The GOM ATOS and the GOM ARAMIS systems were applied to characterize lithium polymer batteries. Discontinuous tests were performed and the battery was discharged to 0 V and then fully charged for both methods. The advantages and disadvantages and the applicability of the two measurement systems were analyzed in this topic.
Highlights
A tremendous demand appeared to produce elements installed in electric vehicles (EV) consuming chemical energy in the last decades
A few highlighted images are presented in Figure 13, where the deformation of the lithium polymer battery as a function of the state of charge (SOC) is shown
The fully discharged state is shown on the left side of the image (0% SOC); the second image belongs to 10% SOC
Summary
A tremendous demand appeared to produce elements installed in electric vehicles (EV) consuming chemical energy in the last decades. The design and production processes of batteries are challenged by different needs and application methods (Dunn et al, 2015). Other types of batteries are required to drive vehicles or in entertainment technology (Ehrlich, 2002). They have a common feature: a higher energy density is needed to operate reliably in the long run (Slattery, Dunn & Kendall, 2021). The energy management, efficient analysis, and prediction of the physical condition of batteries used in electric vehicles is a priority in favor of economic usage (Rezvanizaniani et al, 2014; Fotouhi et al, 2016; Zheng et al, 2016; Zhu, Wierzbicki & Li, 2018; How et al, 2019; Wang et al, 2020). The authors tested lithium polymer batteries applied to vehicles and entertaining technology products to determine deformities
