摘　　要：针对动力锂电池模型难以准确估算的非线性特性,推导并建立RC电池等效模型方程,通过大量充放电实验数据,应用最小二乘法辨识出模型参数,仿真结果验证了RC等效模型的准确性。The inestimable nonlinear characteristic of power lithium-ion battery was considered, and then the equation of RC equiualent circuit was deduced and established. The massive data of charge-discharge test was presented. The accuracy of the RC equivalent model was identified and the model parameters were distinguished by least-squares method.
