摘　　要：建立合适的寿命退化仿真模型是研究锂离子电池寿命预测方法的基础。首先介绍了影响锂离子电池寿命退化的因素,之后总结归纳了国内外常用的寿命预测模型,并针对现有锂离子电池实验数据的特点,结合模型的可行性和精确性考虑,提出了一种双指数容量衰减仿真模型,并对模型参数进行初始化。利用锂离子电池测试数据集完成的验证表明,上述双指数容量衰减仿真模型构建简易、拟合优度高,能较好的模拟锂离子电池寿命退化的过程,具有较强的应用价值。The establishment of a suitable simulation model of life degradation is the basis for studying the life prediction method of Lithium - ion batteries. Firstly we introduced the factors influencing the life of Lithium - ion battery, and then summarized the life prediction simulation models. On this basis, considering the characteristics of the existing Lithium - ion battery experimental data, the feasibility and precision of the model, a simulation model of double exponential capacity attenuation was proposed, and the model parameters were initialized. The simulation re- suits of the Lithium - ion battery tests with a data set show that the proposed simulation model with double exponential capacity attenuation is easy to be constructed and has a high goodness of fit and can be used to simulate the life deg- radation of Li - ion battery, and has a strong application value.
