摘要： A method of finding black spots in a separator according to an embodiment includes taking out a separator from a rechargeable battery cell; removing a foreign material of the separator surface; obtaining a first image for a portion where black spots are estimated in the separator by using a first camera and recording a position of the first image; first selecting the part where black spots are estimated by using the first image, and acquiring a second image for black spots and a foreign material other than black spots in the separator by using a second camera for the recorded position; and secondary selecting black spots by deep learning the first image and the second image with a deep learning software and then displaying the position of the black spots after.

摘要： A battery pack including: a plurality of battery cells; a housing accommodating the plurality of battery cells; a temperature measuring sensor extending from outside the housing to inside the housing along an axial direction by passing through a mounting hole in the housing; and a sealing member. The temperature measuring sensor includes: a pillar part extending along the axial direction; a locking jaw member extending from a lower position of the pillar part to an upper position toward the housing along the axial direction, extending to follow both the axial direction and a crossing direction crossing the axial direction, and providing an elastic bias force along the crossing direction away from the pillar part with respect to the mounting hole in the housing; and an expansion part expanding from a circumference of the pillar part to cover the mounting hole at an upper portion of the mounting hole along the axial direction. The sealing member is between the expansion part of the temperature measuring sensor and the housing and surrounds the mounting hole.
