  "textContent": "The disclosure provides a thermal runaway detection circuit and method, and relates to batteries. The thermal runaway detection circuit includes: a sensing module (P1) including a sensing cable, wherein a distance between at least a portion of the sensing cable and a cell of a battery pack is less than a temperature sensitive distance threshold; a detection module (P2) connected to the sensing cable and including at least one set of voltage dividing resistors, wherein one end of each set of voltage dividing resistors is connected to a first power supply terminal (VI), and the other end of each set of voltage dividing resistors is connected to the ground, and each set of voltage dividing resistors includes at least two voltage dividing resistor sets connected in series; a processing module (P3) connected to the detection module (P2), wherein the processing module (P3) is configured to obtain thermal runaway detection data, and determine whether thermal runaway occurs in the battery pack based on the thermal runaway detection data, wherein the thermal runaway detection data includes battery pack data and sampled data collected from sampling points, and the sampling points are disposed between the two connected voltage dividing resistor sets. The technical solutions in the present disclosure can improve safety of the battery pack.",
