Abstract
A battery assembly includes a battery cell, conductive bus bar, and printed circuit board assembly (PCBA). A cell tab of the battery assembly has a first portion extending from a perimeter edge of a pouch and a second portion arranged orthogonally with respect to the first portion. The bus bar defines a tab slot through which the first portion extends, and has a major surface adjacent to the second portion. The PCBA defines an elongated welding window orthogonal to a longitudinal axis of the PCBA. The PCBA is mounted over the bus bar such that surface area of the second portion is exposed through the welding window, and in turn is welded to the bus bar through and within the welding window. A spring element may be positioned between the carrier frame and the PCBA. A method of making the battery assembly is also provided.
