新能源汽车动力系统安全性能表征参数数据集

本数据集主要为参数指标名称、线上评估/线下检测、参数阈值（三元锂电池、磷酸铁锂电池、混合动力系统、燃料电池）及参数指标说明。 新能源汽车动力系统安全性能表征参数验证数据：实验验证数据，涵盖2种不同材料体系（LFP、NCM）常见车型电池包、3项安全特征参数云端数据、8种工况下特征参数实验数据，其中包括NEDC，低温加速、低温制动、低温行驶、高温行驶、高温快充、低温充电及常温充放电；仿真验证数据，包括2种不同材料体系（LFP、NCM）电池全生命周期下容量衰减模型数据、最大压差参数随电池衰减变化数据、特征参数在内短路触发前后的突变特征数据。数据量：109M。

This dataset primarily includes parameter indicator names, online evaluation and offline detection items, parameter thresholds applicable to ternary lithium batteries, lithium iron phosphate batteries, hybrid power systems, and fuel cells, as well as descriptions of the parameter indicators. The dataset contains validation data for safety performance characterization parameters of new energy vehicle power systems, which is divided into two categories: experimental validation data and simulation validation data. The experimental validation data covers battery packs of common vehicle models from two different material systems (LFP and NCM), cloud-based data of 3 safety characteristic parameters, and experimental data of characteristic parameters under 8 working conditions, including NEDC, low-temperature acceleration, low-temperature braking, low-temperature driving, high-temperature driving, high-temperature fast charging, low-temperature charging, and normal-temperature charging and discharging. The simulation validation data includes capacity decay model data of batteries from two different material systems (LFP and NCM) across their full life cycles, data of maximum voltage difference parameters varying with battery degradation, and mutation characteristic data of characteristic parameters before and after the triggering of internal short circuits. The total data volume of this dataset is 109 MB.
