Abstract

An increasing number of applications with diverse requirements incorporate various battery technologies. Selecting the most suitable battery technology becomes a tedious task as several aspects need to be taken into account. Two of the key aspects are the battery characteristics under temperature variations and their degradation. While numerous contributions using tailored assessment methods to evaluate both aspects for a particular application exist in the literature, a general methodology for analysis is necessary to enable a quantitative comparison between different technologies. We propose in this paper a novel methodology, based on performance indicators, to quantify the potential and limitations of a battery technology for diverse applications sharing a similar operational profile. A quantification of phenomena such as the influence of high and low temperatures on the battery, or the effect of cycling and state of charge on battery aging is obtained. In pursuit of these indicators, an experimental procedure and the fitting of aging model parameters that allow their calculation are proposed. As an additional outcome of this work, a general aging model that allows comprehensive analysis of aging behavior is developed and the trade-off between experimental time and accuracy is analyzed to find an optimal experimental time between 2 and 4 months, depending on the studied battery technology. Finally, the proposed methodology is applied to four battery technologies in order to show its potential in a real case-study.

电池技术比较评估方法：实验设计、建模、性能指标和四种技术的验证

越来越多具有不同要求的应用采用了各种电池技术。选择最合适的电池技术是一项繁琐的工作，因为需要考虑多个方面。其中两个关键方面是温度变化下的电池特性及其降解。虽然文献中有许多文章采用量身定制的评估方法来评估特定应用的这两个方面，但有必要制定一种通用的分析方法，以便对不同技术进行定量比较。我们在本文中提出了一种基于性能指标的新方法，用于量化电池技术在不同应用中的潜力和局限性，这些应用具有相似的运行特征。我们对一些现象进行了量化，如高温和低温对电池的影响，或循环和充电状态对电池老化的影响。为了追求这些指标，我们提出了一种实验程序和老化模型参数拟合方法，以便对其进行计算。作为这项工作的额外成果，还开发了一个可全面分析老化行为的通用老化模型，并分析了实验时间和准确性之间的权衡，以根据所研究的电池技术，找到 2 至 4 个月之间的最佳实验时间。最后，将所提出的方法应用于四种电池技术，以展示其在实际案例研究中的潜力。

期刊介绍： Applied Energy serves as a platform for sharing innovations, research, development, and demonstrations in energy conversion, conservation, and sustainable energy systems. The journal covers topics such as optimal energy resource use, environmental pollutant mitigation, and energy process analysis. It welcomes original papers, review articles, technical notes, and letters to the editor. Authors are encouraged to submit manuscripts that bridge the gap between research, development, and implementation. The journal addresses a wide spectrum of topics, including fossil and renewable energy technologies, energy economics, and environmental impacts. Applied Energy also explores modeling and forecasting, conservation strategies, and the social and economic implications of energy policies, including climate change mitigation. It is complemented by the open-access journal Advances in Applied Energy.
