Claim 7:
8. A method for monitoring and suppressing swelling of a battery cell and its nonconductive housing, comprising:
affixing a conductive stretchable element to the nonconductive housing;
sensing a resistance variation value of the conductive stretchable element as a result of the conductive stretchable element having been stretched due to swelling of the battery cell;
in response to the resistance variation value, controlling a charging device to decrease a supply voltage to the battery cell; and
in response to the resistance variation value exceeding a predetermined threshold, closing a switch disposed between the battery cell and the conductive stretchable element to cause the battery cell to discharge through the switch and the conductive stretchable element.
