Abstract
Official abstract text for this publication.
A sensor for detecting leaked cooling fluid in a battery pack or container. The sensor is part of a sensor wire, where one end of the wire is electrically coupled to the positive terminal or the negative terminal of the battery pack and the other end of the wire is positioned at a location where the leaked cooling fluid may accumulate. A fault isolation detection circuit monitors a voltage output from the sensor and determines that there is a cooling fluid leak if the measured voltage potential is greater than a predetermined voltage threshold.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for detecting a cooling fluid leak from a liquid cooled battery pack, said battery pack including a positive terminal and a negative terminal, said method comprising: electrically coupling a first end of a sensor wire to one of the positive terminal or the negative terminal of the battery pack from which the cooling fluid leak is to be detected; positioning a second end of the sensor wire at a location where leaked cooling fluid may accumulate;…
