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.

    一种热失控检测的方法,能够有效提高换电柜(13)和换电站(11)的安全性能。方法包括:电池管理单元BMU(131)根据换电柜(13)中电池(142)的电池参数,确定换电柜(13)是否发生了热失控,电池参数包括电池(142)中电池单体的温度和/或电池单体的电压;若确定换电柜(13)发生了热失控,BMU(131)向换电站(11)的站控系统(151)发送故障信息,故障信息用于指示换电柜(13)发生了热失控。
