Patent number: 11949270Abstract: 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.
