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.
