Abstract: A battery module for monitoring and suppressing battery swelling and interacting with a charging device includes a battery cell disposed in a nonconductive housing, a conductive label affixed to the nonconductive housing, a switch, and a controller. The battery cell is charged via a supply voltage from a charging device. The switch is coupled between the battery cell and the conductive label. The controller detects a resistance variation value ?R of the conductive label as result of swelling of the nonconductive housing, and generates a corresponding control voltage. As the resistance of the conductive label increases, the supply voltage may be adjusted downward according to the control voltage. If the resistance variation value ?R conductive label is greater than or equal to a predetermined threshold, the controller closes the switch, and the battery cell may then fully discharge through the conductive label.
