Cover assembly for a battery module

A cover assembly for a battery module that includes battery cells arranged side-by-side in a stacked configuration, the cover assembly configured to be coupled to the battery cells, the cover assembly comprising:

• a housing configured to extend a length across the battery cells, the housing including multiple posts;
• a plurality of bus bars held by the housing, the bus bars configured to electrically connect to corresponding positive and negative cell terminals of the battery cells to electrically connect adjacent battery cells;
• and
• an electrical cable extending across the bus bars, the cable being electrically connected to the bus bars to monitor a voltage across each of the battery cells, the cable including plural electrical conductors and a dielectric insulator surrounding the conductors and extending between the conductors to electrically isolate the conductors from one another, the conductors of the cable including exposed segments exposed through the dielectric insulator that are electrically connected to corresponding bus bars at junction locations via a bonding layer applied between the exposed segment and the corresponding bus bar, wherein the cable is mechanically secured to the housing at fixation locations to provide strain relief for the cable at the junction locations,
• wherein the cable defines multiple openings at the fixation locations, each opening extending through a different one of the conductors and separating the corresponding conductor into two disjointed segments that are electrically isolated from one another, wherein each of the posts of the housing extends through a different one of the openings in the cable to mechanically secure the cable to the housing.
