摘要
蓄电池荷电状态SOC(State of Charge)是电池使用过程中的重要参数。为了能够精确地预测蓄电池剩余电量,本文在对3种SOC基本估算方法分析和比较的基础上,采用了一种新的以蓄电池端电压和内阻为参数进行估计的方法,并按此种方法进行了蓄电池放电试验。试验结果表明这种算法在SOC小于0.45时计算精确,能用来预测混合动力汽车蓄电池剩余电量。
The State of Charge （SOC） is an important parameter of the lead acid battery in use. To predict the residual capacity accurately,a new estimation method using the terminal voltage and the internal resistance of the battery is proposed. It is based on the discussion of the three basal estimation methods. The discharging experiments are made and good result is obtained. The result indicates that the SOC can be estimated accurately with this method. So the method can be used for predicting the residual capacity for lead acid battery used in ISAD HEVS
