摘要
介绍了一种基于铅酸蓄电池的三阶动态模型,并对其采用Simulink的S函数进行了仿真研究。考虑到铅酸蓄电池充放电特有的非线性及温度特性,建立了蓄电池的荷电状态、放电深度与充放电电流电压之间的动态关系。Simulink中可用S-Function方便灵活地构建各种自定义仿真模型,使用Simulink中的S-Function builder模块快速构建了蓄电池动态模型。仿真结果表明,铅酸蓄电池的三阶动态模型完全能够满足应用需求。
A three-order dynamic model based on the lead-acid battery is introduced,and simulation research is conducted on this model by using Simulink-S function. Under adequate consideration of the non-linear and temperature characteristics of the lead-acid battery,this model establishes a dynamic relationship between the charging status,discharging degree and the charging / discharging current and voltage. In Simulink,S-Function can be used for easy,flexible establishment of various user-defined simulation models. The Simulink S-Function builder module is used to build up a dynamic battery model quickly. The simulation result shows that the 3-order dynamic model of the lead-acid battery can fully meet application demands.
