储能电池加速老化测试数据集
收藏资源简介：
2021YFB2401803-001--储能电池加速老化测试数据集依托于国家重点研发计划项目（2021YFB2401800）。在“双碳”目标背景下，储能电池健康状态与寿命评估对电网安全至关重要。该数据集旨在为电池失效机理分析、寿命预测与健康管理提供高质量数据支撑。数据通过实验室加速老化测试产生，采用磷酸铁锂/石墨软包电池，涵盖单应力（温度、倍率、功率、过放）、双应力（温度-功率、温度-倍率等）及多应力耦合（温度-倍率-过放等）多种条件。测试遵循国家标准与专家评审方案，并设平行样确保数据可靠。数据集包含三个部分：单应力、双应力耦合与多应力耦合循环老化数据，记录容量、能量、直流内阻等参数随时间（循环圈数）变化。总数据量约11.75GB，格式包括.ndax、.xml、.xlsx等。数据集旨在在较短时间内有效复现电池在实际多年使用中可能出现的老化路径与失效模式，为储能电池加速老化方法构建提供高质量的初始数据。
2021YFB2401803-001 Energy Storage Battery Accelerated Aging Test Dataset is developed based on the National Key R&D Program of China (Grant No. 2021YFB2401800). Against the backdrop of the "Dual Carbon" goals, the state of health (SoH) and lifespan evaluation of energy storage batteries are critical to grid security. This dataset aims to provide high-quality data support for battery failure mechanism analysis, lifespan prediction and health management. The data is generated via laboratory accelerated aging tests using lithium iron phosphate/graphite pouch cells, covering various test conditions including single stressors (temperature, charge/discharge rate, power, over-discharge), dual-stressor combinations (temperature-power, temperature-rate, etc.), and multi-stressor coupling scenarios (temperature-rate-over-discharge, etc.). The tests comply with national standards and expert-reviewed protocols, and parallel samples are set up to ensure data reliability. The dataset consists of three parts: cyclic aging data under single stressors, dual-stressor coupling, and multi-stressor coupling, which records the changes of parameters such as capacity, energy, and direct current (DC) internal resistance over time (number of cycles). The total data volume is approximately 11.75 GB, with file formats including .ndax, .xml, .xlsx, etc. This dataset is designed to effectively reproduce the aging paths and failure modes that batteries may experience during years of actual service within a relatively short period, providing high-quality initial data for the development of energy storage battery accelerated aging methods.
