摘　　要：为了更加准确便捷地研究锂离子电池的性能和健康状态,提出了一种热耦合SP+模型。首先,在单粒子模型的基础上,增加液相扩散作用和电池温度的描述;然后,针对模型参数过多、不易应用的问题,进行参数化简融合,并保留了其清晰的物理含义;最后,对该模型进行不同工况下端电压、容量和表面温度的验证。实验结果证明该模型有很高的仿真精度。热耦合SP+模型的提出使锂离子电化学模型的表达形式和计算过程得到了简化,增加了热行为的仿真,为电化学模型应用于电池管理系统提供了理论基础。In order to study the performance and health status of Lithium-ion battery more accurately and conveniently, this paper puts forward a thermal coupling SP＋ model. Firstly, the thermal coupling SP ＋ model increases the liquid diffusion effect and the description of the battery thermal basing on the single particle model. Secondly, the parameters are simplified and combined to solve the difficulty in application for too many parameters, and the parameters still retain clear physical meaning respectively. Thirdly, verify the model in the aspects of terminal voltage, capacity and temperature under different working conditions. The experiments prove that the model has a high simulation precision. The proposing of the theImal coupling SP＋ model simplifies the expression and the calculation of electrochemical model, adding the description of the thermal behavior and providing theoretical basis for the application of electrochemical model in the field of battery management system.
