BATTERY MODULE WELDING VERIFICATION SYSTEM AND METHOD FOR SAME

摘要

Provided are a battery module welding verification system and a method for same. A battery module includes a first battery cell and a second battery cell, and interconnection members are welded onto each of the first and second tabs of the respective first and second battery cells. The system includes a gripping device provided with a first gripping finger and a second gripping finger that are in contact with the interconnection members. The system further includes battery cycling device that charges/discharges the battery module and is electrically connected to thereto. In addition, the system includes a temperature sensor, which is located at one of the first or the second gripping fingers, and generates a first signal that indicates the temperature of the interconnection members when the battery cycling device discharges the battery module.
