Abstract
A detection device for detecting a thermal runaway condition in a rechargeable automotive traction battery that includes a closed traction battery housing for receiving at least a plurality of rechargeable electrochemical energy cells and being equipped with a safety relief valve. The detection device includes a force-sensing resistor. The force-sensing resistor has flexible substrates separated by a spacer member and defining a force-sensitive area, and a venting duct connecting a space between the two substrates and a vent outlet. At least the force-sensitive area of the force-sensing resistor is placeable inside the traction battery housing, and the vent outlet is fluidically connectable to a detection region of an interior space of the traction battery housing which is located in the vicinity of the safety relief valve.
