<P>PROBLEM TO BE SOLVED: To detect liquid leakage from a battery pack if the leakage occurs. <P>SOLUTION: A battery pack and a liquid leakage detection system are provided. The system includes first and second wire grids and an open-cell foam layer. The first and second wire grids are disposed on first and second sides, respectively, of the foam layer. The foam layer allows at least a portion of liquid in contact with the foam layer to migrate from the first side to the second side. The system further includes an insulating mat disposed between the second wire grid and a tray. The system further includes a resistance measuring device that outputs a first signal indicative of a resistance level between the wire grids. The system further includes a microprocessor that compares an amplitude of the first signal with a threshold value, and outputs a second signal if the liquid is detected based on the comparison. <P>COPYRIGHT: (C)2013,JPO&INPIT |
