A thermal runaway detection method can effectively improve the safety performance of a battery changing cabinet (13) and a battery changing station (11). The method comprises: a battery management unit (BMU) (131) determining whether thermal runaway occurs in a battery changing cabinet (13) according to battery parameters of a battery (142) in the battery changing cabinet (13), the battery parameters comprising the temperature of a single battery in the battery (142) and/or the voltage of the single battery; if it is determined that the battery changing cabinet (13) is subjected to thermal runaway, the BMU (131) sends fault information to a station control system (151) of the battery changing station (11), and the fault information is used for indicating that the battery changing cabinet (13) is subjected to thermal runaway.
