摘　　要：以常用锂电池为研究对象,通过以瞬间电流变化情况,研究分析了锂电池内部电阻特性,提出了以电路模型为基础的内阻估算方法。通过过渡过程实验,研究结果表明,锂电池内阻在不同荷电状态(State of Charge,SOC)下呈现规律性的变化,提出了一种实时监测电池内阻的估算方法。In conventional lithium battery as experimental subject, by instantaneous current variation, studied and analyzed the characteristics of the lithium battery internal resistance, and proposed an internal resistance estimation method with model-based circuit. Through the transition process＇ s experiment, the result showed that the lithium battery internal resistance change appears regularity in different state of charge（State of Charge,SOC）, and proposed an estimating method for real-time monitoring the internal resistance of the battery.
