The invention provides thermal event detection of a traction battery pack. A method of detecting a thermal event associated with a battery assembly of an electrically powered vehicle includes, among other things, obtaining a temperature reading from a sensor associated with a region of the battery assembly and evaluating whether the sensor is marked with a first identifier or a second identifier. The first identifier indicates that the temperature reading is reliable. The second identifier indicates that the temperature reading is unreliable. If the sensor is tagged with the first identifier, the method detects a thermal event associated with the battery assembly based on the temperature reading originating from the sensor.

    本公开提供了“牵引电池组的热事件检测”。一种检测与电动化车辆的电池总成相关联的热事件的方法除了其他之外包括从与所述电池总成的区域相关联的传感器获得温度读数并且评估所述传感器是用第一标识符还是用第二标识符标记的。所述第一标识符指示所述温度读数是可靠的。所述第二标识符指示所述温度读数是不可靠的。如果所述传感器是用所述第一标识符标记的,所述方法则基于源于所述传感器的所述温度读数检测与所述电池总成相关联的热事件。
