Lead assembly for battery cell monitoring

A battery comprising:

• a plurality of battery cells;
• a plurality of posts, each post of the plurality of posts electrically coupled to one or more battery cells of the plurality of battery cells;
• a case housing the plurality of battery cells and at least a first portion of each post of the plurality of posts;
• a cover being coupled to the case and having a plurality of openings, at least a second portion of each post protruding through a corresponding opening and extending away from the cover;
• a lead assembly comprising:
• a plurality of leads, each lead being electrically couplable to the second portion of one post of the plurality of posts;
• and
• a lead assembly layer physically couplable to the cover of the battery, the lead assembly layer having a first surface and a second surface opposite the first surface, at least a portion of each lead of the plurality of leads being positioned:
• between the first surface and the second surface of the lead assembly layer;
• or
• on the first surface of the lead assembly layer.

A method for assembling a lead assembly of a battery, the lead assembly comprising a plurality of leads and a lead assembly layer, the lead assembly layer having a first surface and a second surface opposite the first surface, the battery comprising a battery management system and plurality of posts associated with a plurality of battery cells, the method comprising:

• arranging a plurality of leads separate from each other;
• molding the lead assembly layer over the plurality of leads or securing the plurality of leads onto the first surface, the molded lead assembly layer comprising the plurality of leads between the first surface and the second surface;
• and
• coupling each lead of the plurality of leads to one post of the plurality of posts and the battery management system.
