Battery Degradation Datasets (Two Types of Lithium-ion Batteries)

This degradation dataset covers two types of lithium-ion batteries, PANASONIC NCR18650BD (3.03 Ah nominal capacity, 3 cells) and GOTION IFP20100140A (27 Ah nominal capacity, 3 cells), named as Dataset #3 and Dataset #5, respectively.
Batteries from datasets #3 and #5 are tested in thermal chambers at 20°C and 45°C, respectively. An ARBIN BT2000 battery test system is employed to cycle the batteries. In each cycle of the battery from Dataset #3, the charge strategy is to charge at a constant current rate of 0.3C until the voltage reaches 4.2V and then hold at 4.2V until the charging current drops below 0.03A; the discharge strategy is to discharge at a constant current rate of 2C. In each cycle of the battery from Dataset #5, the charge strategy is to charge at a constant current rate of 1C until the voltage reaches 3.65V and then hold at 3.65V until the charging current drops below 1.35A; the discharge strategy is to discharge at a constant current rate of 1C. The charging curves extracted from the constant-current charging phase of the cycles are integrated into the datasets.
This supports the Data availability of "Deep learning to estimate lithium-ion battery state of health without additional degradation experiments".

本退化数据集涵盖两类锂离子电池，分别为松下（PANASONIC）NCR18650BD（标称容量3.03 Ah，共3节）与国轩高科（GOTION）IFP20100140A（标称容量27 Ah，共3节），二者分别被命名为数据集#3与数据集#5。
数据集#3与#5中的电池分别在20℃与45℃的恒温箱中进行测试，测试采用ARBIN BT2000电池测试系统完成电池循环测试。
对于数据集#3内的电池，单次循环的充电策略为：以0.3C恒定电流充电至电压达到4.2V后，维持4.2V恒压充电直至充电电流降至0.03A以下；放电策略为以2C恒定电流进行放电。
对于数据集#5内的电池，单次循环的充电策略为：以1C恒定电流充电至电压达到3.65V后，维持3.65V恒压充电直至充电电流降至1.35A以下；放电策略为以1C恒定电流进行放电。
研究人员从各循环的恒流充电阶段提取充电曲线，并将其整合入上述数据集。
本数据集可为《无需额外退化实验的锂离子电池健康状态深度学习估算》一文的数据可用性说明提供支撑。
