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.

A method of sensing a state of a battery cell, the method comprising:
- 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,
- wherein the height information is extracted from height information of an upper surface of a wall forming perimeter of the mounting unit and height information of the tab.
A device of sensing a state of a battery cell disposed on an upper surface of a mounting unit and including a tab, the device comprising:
- an image acquisition unit positioned on an upper part of the mounting unit and configured to acquire an image of the mounting unit and the battery cell;
- and
- a controller connected to the image acquisition unit and configured to extract height information of the tab with respect to a point of the mounting unit from the image,
- wherein the height information is extracted from height information of an upper surface of a wall forming perimeter of the mounting unit and height information of the tab.
