1. A computing apparatus for performing a real-time battery stabilization using battery state estimation, the computing apparatus comprising:
- one or more sensors configured to sense charging voltage data for a current battery and for a plurality of batteries at a battery life termination point, wherein the sensed charging voltage data for the plurality of batteries at the battery life termination point is pre-stored; and
one or more processors, in communication with the one or more sensors, configured to;
extract partial data corresponding to a section from the sensed charging voltage data;
determine a first distance between data extracted from pre-stored charging voltage data of an initial battery life and the partial data extracted from the sensed charging voltage data of the current battery, for reducing a computation or calculation workload using the partial data in the determining of the first distance;
determine a second distance between the data extracted from the pre-stored charging voltage data of the initial battery life and data extracted from the pre-stored charging voltage data of the plurality of batteries at the battery life termination point;
determine a score using the first distance and the second distance; and
estimate an abnormal state of the current battery using the score, such that the real-time battery stabilization is provided using a result of the estimating.
