Peukert定律预测锂离子电池倍率容量

Rate capacity prediction for Li-ion battery using Peukert law

开展电池在不同环境温度及荷电状态下的静置老化实验。根据电池的容量和内阻变化情况,构建电池老化经验模型,利用Peukert定律预测电池在0.1 C、0.5 C和1.0 C等不同倍率下容量随静置时间的变化,预测误差为±4%。

Different calendar aging experiments were conducted by varying ambient temperature and state of charge（SOC）.Cell aging behavior was analyzed with the consideration of temperature and SOC.Empirical aging models were developed based on the variation of cell capacity and resistance during the test.The capacities of aged cell at 0.1 C,0.5 C and 1.0 C were predicted using Peukert law with ± 4% error.
