磷酸铁锂电池单体热失控试验数据集

该数据的采集时间为2023年10月25日，采集地点在应急管理部天津消防研究所第一试验基地，燃烧试验馆。采集设备主要是横河无纸记录仪，气体分析仪MIC-600-5-A，K型热电偶、热流计TS-10C、摄像头DS-2CD6425FW，数据处理软件为Origin，所有设备情况良好。 开启电池舱内气体分析仪，通过过充的方式使电池发生热失控。试验舱中安装三列风冷电池箱的电池簇，三列电池簇中选取5个电池箱作为试验对象，其中中间电池箱为目标电池箱，箱内安装5只实体电池，其余部位用模拟电池填充，5只电池紧固一起组成电池模组置于电池箱内，电池单体之间、电池正负极、电池侧面等位置布置热电偶（T1-T9），如图2所示，参考电池箱内均装有模拟电池。电池簇内其他电池箱为空的电池箱，如图1所示。将放置电池的电池箱置于电池簇支架的中间位置，该电池箱标记为A，与其相邻的上部、下部、左部和右部位置分别放置相同规格的电池箱，分别记录为D、E、C、B，在AC、AB、AE和AD之间分别设置热电偶（TAD、TAC、TAB、TAE），如图3所示。距离电池箱水平距离700mm处布置5个热电偶，测量温度梯度，布置如图4所示。Data was collected on October 25, 2023, at the Combustion Test Hall of the First Test Base of the Tianjin Fire Research Institute of the Ministry of Emergency Management. The data collection equipment mainly included Yokogawa paperless recorder, gas analyzer MIC-600-5-A, K-type thermocouples, heat flow meter TS-10C, camera DS-2CD6425FW, and the data processing software was Origin. All equipment was in good working condition. The gas analyzer inside the battery compartment was activated, and thermal runaway of the battery was induced via overcharging. Three columns of air-cooled battery clusters with battery cabinets were installed in the test chamber. Five battery cabinets were selected as test specimens from the three columns of clusters, among which the middle cabinet was the target one. Five physical batteries were installed inside the target cabinet, and the remaining spaces were filled with simulated batteries. The five physical batteries were fastened together to form a battery module placed within the cabinet. Thermocouples (T1-T9) were arranged at positions between individual battery cells, at the positive and negative terminals of the batteries, on the side surfaces of the batteries, and other relevant locations, as shown in Figure 2. All reference battery cabinets were equipped with simulated batteries. The remaining battery cabinets in the cluster were empty, as shown in Figure 1. The loaded battery cabinet (labeled as A) was placed at the central position of the cluster rack. Battery cabinets of the same specification were placed at its upper, lower, left, and right adjacent positions, which were respectively recorded as D, E, C, and B. Thermocouples (TAD, TAC, TAB, TAE) were respectively installed between AC, AB, AE, and AD, as shown in Figure 3. Five thermocouples were arranged at a horizontal distance of 700 mm from the target battery cabinet to measure the temperature gradient, with the layout shown in Figure 4.
