Beschreibung
Zusammenfassung:	A weld validation system and method for a battery module are provided. The battery module has first and second battery cells and an interconnect member welded to first and second tabs of the first and second battery cells, respectively. The system includes a gripping device having first and second gripping fingers contacting the interconnect member. The system further includes a temperature sensor that generates a first signal indicative of a temperature of the interconnect member when a battery cycling device is discharging the battery module. The system further includes a computer that determines a first temperature value indicative of the temperature of the interconnect member based on the first signal.
