摘要： A system for testing thermal runaway in a battery cell includes a first layer of first dielectric material at least in part wrapped around the battery cell, and a wire at least in part wrapped around the first layer of first dielectric material. The system further includes a second layer of second dielectric material at least in part wrapped around the wire, and a power source configured to supply power to the wire. In an example, the first layer of first dielectric material includes a polyimide film, and the second layer of second dielectric material includes mica. The system further includes a temperature sensor in contact with the first layer, the second layer, and/or the battery cell. A controller is to receive a temperature reading from the temperature sensor, and control a power supplied by the power source to the wire, based at least in part on the temperature reading.
