摘要

提出了一种估算VRLA蓄电池容量的新方法。重点放在操作条件上，不包括老化的影响。该方法是基于对放电开始区域的分析，即所谓的初始放电。实验结果表明，从该区域提取的参数与电池容量有较强的相关性。这已经在一系列良好的操作条件下得到了验证，包括放电速率和环境温度。与现有方法相比，该方法的主要优点是;a)简单，可在低电平控制器内实时在线实现。b)放电时间很短(大约2分钟就足够了)。c)估计相对电池容量的准确度优于&5%。

Estimation of VRLS battery capacity using the analysis of the coup de fouet region

This paper presents a novel approach for estimating the capacity of VRLA batteries. Emphasis is placed on operating conditions and exclude the effects of ageing. The approach is based on the analysis of the start of discharge region known as the coup defouet. Experimental results reveal that parameters extracted from this region are strongly correlated to battery capacity. This has been verified for a good range of operating conditions including discharge rate and ambient temperature. The main advantages of the approach compared to existing methods are; a) Simple and can be implemented on-line within low level controllers in a real-time mode., b) Requires a very short duration discharge (in the order of 2 minutes is sufficient)., and c) An accuracy of estimating relative battery c‘apacity of better than &5% may be obtained.
