基于小波复合模型的锂电池阻抗特性研究
Characteristic study of impedance of Li-ion battery based on wavelet mix model
摘要
Abstract
Power storage system is the most important supporting part of energy bidirectional flowing of smart grid, and large-scale group technology is the development bottleneck of large-scale power storage system. By combining Li-ion battery equivalent circuit model with wavelet analysis on the basis of discharging characteristic of Li-ion battery, analyzing the 3-D relationship among resistance of battery, SOC and time of discharge, the conclusion that the trend of resistance of battery was different in different phase was presented. It was also the basic theory judgement for single battery removing of batteries manages system. And it might also provide a reference for precise estimate of SOC.关键词
