Filtration of faulty dried plates of lead-acid battery with digital image processing

The positive plates of lead acid batteries are dried in Tunnel Drying Oven in order to remove moisture. During the drying process, plates are suffered from paste crackness, thermopassivation and burning. Also moisture level is not achieved up to mark and some un-formed plates that need to be filtered out. Digital Image Processing technique is exploited to filter out the faulty plates after the process of drying. In addition, an automated moisture check is also introduced in the existing procedure of TDO. The validity of the proposed model and algorithm is investigated through observations and experiments.
