The adoption of the Electric Vehicle requires a switch towards a circular system to reduce their environmental impact. Under this framework, the correct sizing of the batteries and avoiding their underuse are key actions. Based on the analysis of real data, this work proposes a model to synthesize current profiles representative of trips containing urban and highway sections. The model is used to generate cycles for common daily driving distances. Different sized batteries are analysed at their beginning and end of life to evaluate their ability to provide the required range. Based on the results, it is suggested that the ongoing trend of battery capacity increase is not justified. The commonly assumed threshold of 70–80% State of Health has proved to be too conservative in most cases, allowing for an extension of the first life that should be individually defined based on functional aspects.

电动汽车的采用需要转向循环系统以减少其对环境的影响。在此框架下，正确选择电池尺寸并避免使用不足是关键措施。基于对真实数据的分析，这项工作提出了一个模型来合成代表包含城市和高速公路路段的行程的当前配置文件。该模型用于为常见的日常驾驶距离生成周期。不同尺寸的电池在其使用寿命开始和结束时进行分析，以评估它们提供所需范围的能力。根据结果​​，建议电池容量持续增加的趋势是不合理的。在大多数情况下，事实证明，通常假设的 70-80% 健康状况阈值过于保守，
