The proposed fault classification technique can also be used for any type of battery application involving different lead acid batteries like VRLA battery, flooded lead acid battery or polymer lead acid battery. Therefore using proposed technique, the reliability of systems having the lead acid battery as a critical component can be enhanced.
Therefore, the anomalies in lead acid battery can be detected by monitoring its parametric degradation. The use of IRT for automatic fault diagnosis of lead acid battery offers the advantage of detecting the early failures in a fast, non-contact and non-invasive manner.
The SOC for lead acid battery is determined from the parameters such as specific gravity (Aylor et al. 1992 ), open-circuit voltage (Mariani et al. 2013 ), cell temperature (Hunter and Anbuky 2003 ), cell voltage (Hariprakash et al. 2004) and Coulometric measurements (Ng et al. 2009 ).
At high temperatures, chemical reaction occurs faster in the cells which cause the rise in the internal resistance and joule heating of lead acid battery. With the lapse of time, degradation failure of battery occurs due to the reduction in its capacity and efficiency.
Different high-temperature lead–acid batteries (12 V battery block—80 Ah) from the same manufacturer, which were intended for back-up applications, were used to develop the following experiments.
