Abstract
A battery pack, or battery pack module, is provided that is configured to respond to a short circuit of moderate current in a manner that minimizes the risk of an initial thermal runaway event propagating throughout the battery pack/battery pack module. In general, the battery pack/battery module allows pre-selection of which cell of the cells comprising the battery pack/battery pack module will be the last cell to respond to the short circuit. As a result, a thermal isolation barrier may be used to separate the preselected cell from the other cells of the battery pack/battery pack module, thereby minimizing the risk of excessive heating and extensive collateral damage.
