Abstract: An apparatus and a method for inspecting a leak of a battery cell are provided. An apparatus for inspecting a battery cell leak to inspect whether a battery cell leaks includes: a vacuum chamber including an upper chamber and a lower chamber and configured to set a receiving space to a controlled pressure different from an external first pressure, the upper chamber and the lower chamber being arranged to face each other with the receiving space for a battery cell therebetween and providing sealing for the receiving space; a vacuum pipe valve fluidly connected to the receiving space for the battery cell to set the receiving space to a second pressure less than the first pressure; and a thickness measuring sensor configured to measure a before-vacuum thickness of the battery cell under the first pressure and measure an after-vacuum thickness of the battery cell under the second pressure.
According to the present disclosure, an apparatus and a method for inspecting a battery cell leak, capable of easily and precisely capturing damage to an exterior material of a battery cell are provided.
