Traction battery pack thermal event detection

A method of detecting a thermal event associated with a battery assembly of an electrified vehicle includes, among other things, obtaining a temperature reading from a sensor associated with an area of the battery assembly, assessing whether the sensor is flagged 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 flagged with the first identifier, the method detects a thermal event associated with the battery assembly based on the temperature reading from the sensor.
