Apparatuses, systems and methods for electronic wearable devices such as smart glasses are described. According to one embodiment, a temple assembly forming part of the smart glasses is disclosed. The assembly can include a temple mechanical connection, a battery carrier, a battery, and a temple body. The temple mechanical connection is configured to form an articulated joint at a first longitudinal end portion thereof with a frame of the wearable electronic glasses. The battery carrier is rigidly attached to the temple mechanical connection at a second longitudinal end portion thereof. The battery is mounted on the battery carrier. The temple body comprises a plastics material, and is configured to house the battery and battery carrier and interface with the second longitudinal end portion of the temple mechanical connection. The battery and battery carrier are generally longitudinally aligned along a longitudinal extent of the temple body, and are configured to form at least part of a structural framework for the temple body.

A battery pack (1) includes a housing (2) and an array (40) of electrochemical cells (80) disposed in the housing (2). The housing (2) includes a container (3) and a lid (30) that closes an open end of the container (3). The container (3) has a base (4), a sidewall (8) that surrounds the base (4), and a spring plate (110) disposed inside the side wall (8) between the cells (80) and the sidewall (8). The spring plate (110) is free standing within the container (3) and applies a spring force to the cell array (40) that restrains the cells (80) along an axis normal to the surface of the spring plates (110). The lid (30) includes inwardly-protruding pins (50, 60) that further restrain the cells (80) within the housing (2).
