Abstract: A method according to an exemplary aspect of the present disclosure includes, among other things, compressing at least one battery module to a desired dimension prior to installing the battery module into an array. Another method according to an exemplary aspect of the present disclosure includes, among other things, inducing a residual stress into a battery module to compress the battery module to a desired dimension prior to being installed in an array. An apparatus, according to an exemplary aspect of the present disclosure includes, among other things, a compression device configured to temporarily compress at least one battery module to a desired dimension prior to installing the battery module into an array.

Abstract: An exemplary busbar assembly includes a first strip including a first material, and a second strip including a second material different than the first material. The first strip extends continuously from a first connector portion to a second connector portion. The first connector portion electrically connects the first strip to a first structure. The second connector portion electrically connects the first strip to a second structure. The first and second strips are both configured to communicate electric current. An exemplary current communication method includes communicating electrical current using both a first strip and a second strip of a busbar. The first strip is made of a first material and bonded to the second strip made of a second material. The first strip extends continuously from a first to a second connector portion. The first connector portion electrically connects to a first structure, and the second connector portion electrically connects to a second structure.
