Abstract
A battery module having a controllable external heat sink and methods of operating the battery module are provided. According to an aspect of the invention, the battery module includes a battery cell, an external circuit connected to the battery cell, and a controller that controls the external circuit. The external circuit includes a first switch and a heat sink. If an internal short circuit within the battery cell is detected, the controller closes the first switch in order to generate heat in the heat sink.
