Abstract:
1. A detection system for detecting a battery thermal event, the detection system comprising: at least one battery; a conductive member comprised of a first end portion, a second end portion, and a region there between, wherein a portion of said region is proximate to an external surface of said at least one battery; a resistance measuring system coupled to said first and second end portions of said conductive member, wherein said resistance measuring system outputs a first signal when said at least one battery is operating within a prescribed temperature range and outputs a second signal when a temperature corresponding to said at least one battery exceeds a predetermined temperature, wherein said predetermined temperature is outside of said prescribed temperature range; and a system controller coupled to said resistance measuring system, wherein said system controller performs a predetermined response when said system controller receives said second signal from said resistance measuring system, said predetermined response selected from the group of responses consisting of (i) activating a warning indicator, (ii) activating a battery cooling system, (iii) activating a fire control system, and/or (iv) transmitting a thermal event notification report via a communication system coupled to said system controller.
