磷酸铁锂电池系统外短路试验数据集

该数据集主要面向锂电池安全性研究与优化设计需求，基于北京理工大学西山实验区的实验平台，通过电化学工作站、充放电仪及高精度数据采集单元采集生成。数据集涵盖电芯单体、模组及电池包在不同荷电状态、环境温度及短路时长条件下的温度、容量、阻抗等多维响应特性，详细记录了短路诱导下的性能演化过程。实验于2021年12月至2022年3月期间完成，使用的设备包括LANHE CT3001B型电池测试仪、贝尔BE-XL-5000A短路试验机等。数据文件总量为772MB，采用.xlsx、.csv及.jpg格式存储，符合GB 28031-2020标准，通过开尔文四线接法及高精度数据采集单元保证采样质量，用于支撑全寿命周期故障多维演化机理图谱和故障-热失控-燃爆全链条征兆集及故障处置知识库的构建。This dataset is tailored for lithium battery safety research and optimal design requirements. It was collected and generated based on the experimental platform in the Xishan Experimental Zone of Beijing Institute of Technology, using electrochemical workstations, charge-discharge testers and high-precision data acquisition units. The dataset encompasses multi-dimensional response characteristics including temperature, capacity and impedance of single battery cells, battery modules and battery packs under different states of charge (SOC), ambient temperatures and short-circuit durations, and thoroughly documents the performance evolution process induced by short-circuit events. The experiments were carried out between December 2021 and March 2022, with the employed equipment including LANHE CT3001B battery testers, Bell BE-XL-5000A short-circuit testing machines, among others. The total size of all data files is 772 MB, stored in .xlsx, .csv and .jpg formats, and complies with the GB 28031-2020 standard. The sampling quality is guaranteed by the four-wire Kelvin connection method and high-precision data acquisition units. This dataset supports the construction of multi-dimensional fault evolution mechanism maps across the full lifecycle, the full-chain symptom set covering fault-thermal runaway-explosion, and the knowledge base for fault handling.
