Abstract: A device and method of sensing a state of a battery cell disposed on a mounting unit are disclosed. The method includes an image acquisition step of acquiring, by an image acquisition unit on an upper part of a mounting unit on which the battery cell is disposed, an image of the mounting unit and the battery cell, a height information extraction step of extracting, by a controller, height information of a tab included in the battery cell with respect to a point of the mounting unit from the image, and a battery cell state analysis step of determining, by the controller, a state of the battery cell based on the height information.

Abstract: A device and method of sensing a state of a battery cell disposed on a mounting unit are disclosed. The method includes a height information acquisition step of acquiring, by a height measurement unit disposed on the mounting unit on which the battery cell is disposed, first height information on a first height that is a height of the height measurement unit with respect to a point of the mounting unit and second height information on a second height that is the height of the height measurement unit with respect to a point of the battery cell, and a battery cell state analysis step of determining, by a controller, a state of the battery cell based on the first height information and the second height information.
