Abstract: The present subject refers to a method for battery fault diagnosis and prevention of hazardous conditions. The method comprises determining a plurality of parameters defined as one or more of current, voltage, or state of charge during operation of a battery-powered device. Further, one or more likelihood ratios related to malfunctioning of the battery are evaluated based on determined parameters. At least one of: a current battery-state or a type of current battery state are determined based on the one or more likelihood ratios as evaluated.

Abstract: Embodiments herein disclose an apparatus and methods for identifying an anomaly in at least one of a re-chargeable battery and at least one component(s) connected to the re-chargeable battery. Embodiments herein relates to the field of battery management systems, and more particularly to apparatus and methods for identification of anomalies in batteries and loads/component(s) connected to the re-chargeable battery. The embodiments herein includes outputting a severity level of the anomaly in the at least one of the re-chargeable battery and at least one component connected to the re-chargeable battery, based on the analyzed plurality of the threshold values of the determined plurality of the characteristic data corresponding to the voltage data and current data, wherein the severity level of anomaly comprise at least one of, a negligent level, a medium level and a critical level.
