Abstract
A method for short detection in a battery pack, the battery pack including a plurality of cells, the method including: connecting a short detection module to the battery pack; determining by the short detection module that the battery pack is at rest; and selecting a first cell in the battery pack for testing for a short, wherein the testing includes: connecting a voltage source to the first cell; measuring a current of the first cell; and determining based on the measured current of the first cell whether the first cell contains a short.
