摘要

电池漏气是不可逆故障的早期可靠指标。本文提出了一种具有催化型传感器的电池内部气体自动检测系统及气体排放源精确定位的重构方法。检测系统采用分布式CO传感器阵列。根据阵列的测量效率考虑了几种阵列结构。重构算法基于快速插值技术,非常适合于实时数据处理。利用气体扩散计算模型对重建方法的精度进行了估计。

Automatic System for Li-Ion Battery Packs Gas Leakage Detection
Battery gas leakage is an early and reliable indicator for irreversible malfunctioning. In this paper is proposed an automatic gas detection system with catalytic type sensors and reconstruction approach for precise gas emission source location inside battery pack. Detection system employs a distributed array of CO sensors. Several array configurations are considered according to their measurement efficiency. Reconstruction algorithm is based on fast interpolation technique very suitable for real time data processing. Estimation of reconstruction method accuracy is made by computational model of gas diffusion.
