Document Type and Number:
WIPO Patent Application WO/2024/075873
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and method for inspecting the quality of a pouch-type secondary battery cell, which are provided to inspect the quality of an electrode plate, a bent area, or a welded area of the pouch-type secondary battery cell, wherein: an alternating current signal generation unit generates an alternating current signal; a magnetic field generation means generates a magnetic field in response to the generated alternating current signal and causes an induced current to flow into the pouch-type secondary battery cell; one or more induced current sensors each detect a signal of the induced current flowing into the pouch-type secondary battery cell; and a control/determination unit compares the detected signal of the induced current with a pre-stored determination range value and determines the quality of the pouch-type secondary battery cell.
