基于Thevenin模型的氢镍电池仿真

Ni-mh battery simulation based on Thevenin model

根据氢镍动力电池的特性,选择一种能反映其内部特性的Thevenin模型。基于此模型,进行氢镍电池复合脉冲实验,用最小二乘递推算法辨识模型参数。然后使用Matlab/Simulink进行仿真,仿真结果表明Thevenin模型可用于氢镍电池仿真,能模拟电池的充放电特性。

According to the characteristics of Ni-MH power battery, a Thevenin model, which could reflect its internal characteristics, was selected. Based on this model and through RLS, the parameters of the Ni-MH batteries composite pulse test were identified. A simulation model was set up based on Matlab/Simulink. The result shows that the Thevenin model can be used to simulate Ni-MH battery and the characterizations of charge.
