摘要： A battery system for storing electrical power and supplying electrical power to a vehicle is provided. The system includes multiple battery packs, and each battery pack includes a plurality of cells (300a, 300b). The cells (300a, 300b) in each battery pack are electrically connected with one another and the multiple battery packs are also electrically connected with one another to combine the total energy output of the cells (300a, 300b) of the system. The electrical connections between at least some of the cells (300a, 300b) include a severable feature(800a, 800b), whereby the electrical connection is severed locally at the severable feature(800a, 800b) in response to an impact force that is in excess of a predetermined magnitude and/or an overcurrent/overtemperature condition.
