摘要

锂离子电池是当今最通用的储能技术之一, 锂电池的可靠性和安全性一直是业界追求的目标, 因此准确监控电池安全状态显得尤为重要. 锂电池内部的热失控是一切锂电池安全问题的根源, 为克服目前锂电池组温度测量系统测温精度不高, 较高温度下长时间工作稳定性不足等问题, 本文提出了一种基于双包层光纤布拉格光栅(FBG)的准分布式锂电池组温度监测系统. 通过搭建4通道16个双包层FBG点位对18650锂电池组进行温度场及鼓包形变监测, 结果表明在0—450 ℃的温度条件下可以精确确定由短路等问题产生异常温度升高的点位, 相应温度灵敏度为10 pm/℃, 分辨率达0.1 ℃, 并且贴于锂电池壳体表面的双包层FBG还可以监测电池壳体表面出现的鼓包形变现象, 其纵向压力应变灵敏度达142 pm/N. 本文的双包层FBG准分布式锂电池组温度场监测系统既可以保证高精度的温度、形变测量, 同时具有良好的稳定性和抗干扰能力, 表明本文的研究工作有望为锂电池组的安全监测和使用提供可靠的理论与实验依据.

Abstract

Lithium-ion battery is one of the most versatile energy storage technologies today, and the reliability and safety of lithium battery have always been the target pursued by the industry all the time, so it is particularly important to accurately monitor the safety status of the battery. Actually, the ultimate cause of all lithium battery safety problems lies in the thermal runaway inside the lithium battery. In order to overcome the current problems of temperature measurement systems, such as low accuracy and insufficient stability for long-time operation at relatively high temperature, a temperature monitoring system of quasi-distributed lithium battery based on double clad Fiber Bragg Grating (FBG) is proposed in this work. After the monitoring of the temperature field and bulge deformation of 18650 lithium battery pack by building 4 channels and 16 double clad FBG points to monitor the temperature field and bulge deformation of 18650 lithium battery pack, the results show that the points with abnormal temperature rise caused by short circuit and other problems can be accurately determined under the temperature of 0–450 ℃, with the corresponding temperature sensitivity of 10 pm/℃, and the resolution of 0.1 ℃. The double clad FBG attached to the surface of the lithium battery shell can also monitor the bulge deformation on the surface of the battery shell, and its longitudinal pressure modification sensitivity is up to 142 pm/N. The temperature field monitoring system of quasi-distributed lithium battery pack based on double clad FBG in this paper can not only ensure high-precision temperature and deformation measurement, but also have good stability and anti-interference ability, which shows that the research work in this paper is expected to provide a reliable theoretical and experimental basis for the safety monitoring and use of lithium battery pack.
