摘要：

在分析铅酸蓄电池剩余电量预测方法的基础上，实现了一种基于蓄电池电动势和内阻的电量模糊预测方法.根据蓄电池电动势与电量的实测数据，拟合出一个经验方程，作为电量预测模型的负反馈环节，从而提高了模糊控制器的精度与稳定性.仿真结果表明，该方法有效可行.

Abstract:

Based on analysis of residual capacity estimation methods for lead-acid batteries, this paper realized a capacity fuzzy estimation method using electromotive force (EMF) and internal resistance of lead-acid batteries. An empirical equation is obtained from measured EMF and internal resistance, which can be used as feedback of the fuzzy model. It improves performance and stability of the fuzzy controller. Simulated results show validity of the method. 

Key words: lead-acid battery; residual capacity; fuzzy control; state of charge (SOC)
