First Claim
Patent Images
1. A method for detecting an internal short circuit in a battery, the method comprising:
- obtaining, by a battery management system, battery gauge data;
estimating, by the battery management system, an internal resistance of the battery using the battery gauge data; and
detecting, by the battery management system, the internal short circuit in the battery by comparing a change in the internal resistance with a pre-defined resistance change threshold value.
