Claim 0:
1. A battery thermal runaway detection system for use within a battery enclosure housing one or more batteries, the detection system comprising:
at least one gas sensor comprising a hydrogen sensor configured to detect greater than 300 ppm hydrogen, or a carbon dioxide sensor configured to detect greater than 1,000 ppm carbon dioxide, and configured to provide a sensed output in real time;
a microcontroller electrically connected to the at least one gas sensor and configured to determine power management and provide a signal conditioned output of a concentration of the hydrogen or the carbon dioxide based on the sensed output from the at least one gas sensor;
a battery controller connected to the microcontroller; and
at least one secondary sensor for detecting a secondary condition of the battery and providing information on a rate of progression of the cell venting and thermal runaway in real time including pressure or temperature, wherein said microcontroller provides a rate of progression of the thermal runaway based on the provided information from said secondary sensor.
