摘要： A battery pack assembly includes battery cells, a first endplate adjacent a first end of the battery cells, a second endplate adjacent an opposite, second end of the battery cells, and a tension member. The first and second endplates are each slidably coupled to the tension member. A compressible member is disposed between the first endplate and a section of an enclosure. The compressible member is configured to compress in response to the battery cells expanding and moving the first endplate toward the section of the enclosure.

摘要： A traction battery assembly includes battery cells of a battery array, and switches of the battery array. The switches are transitionable between a first configuration and a second configuration. When the switches are in the first configuration, the battery cells of the array are partitioned into a first number of groups of battery cells in parallel with each other. When the switches are in the second configuration, the battery cells of the array are partitioned into a different, second number of groups of battery cells in parallel with each other.

摘要： This disclosure relates to a battery for an electrified vehicle and a corresponding method. In particular, the battery and method accommodate for variable cell thickness. An example method of this disclosure includes inserting a separator between a first battery cell and a second battery cell. The separator has a thickness based on a thickness of the first battery cell and the second battery cell. This disclosure has a number of benefits. Among them, the method may be used to provide a battery array with a desired overall length despite differences in individual cell thickness. In turn, this leads to improved battery performance and lifespan.
