摘要:
A method is provided that achieves improved battery pack performance, system reliability and system safety while impacting only a small region of the battery pack/battery module, and thus having only a minor impact on battery pack cost, complexity, weight and size. The battery pack/battery module is designed such that the fusible interconnects associated with a single battery, or a specific fusible interconnect associated with a single battery, will be the last interconnect(s) to fuse during a short circuit event. The risk of sustained arcing for the predetermined interconnect(s) is minimized through the use of rapid clearing interconnects. As a result, the risk of damage and excessive heating is also minimized.
