ELECTRIC DEVICE ASSEMBLY AND ELECTRIC DEVICE WITH FILM OUTER COVERING

摘要

A battery pack (80) has parallel placement modules (50) each containing two parallelly arranged battery cells (20A, 20B). An airflow channel (65) is formed between adjacent parallel placement modules, and cooling air passes through the channel. Pressing members (60) each have a cavity (61) composed of a solid section (66) and a thin wall section (61a) and the members are stacked on each other. The cavity (61) forms a cooling air channel. Cooling air fed to the cooling air channel is sent to the battery cell (20B) in the back of the channel and fed to the center side of the battery cell (20B). A region A of the solid section (66) holds an electrode tab (25), and in a region B of the solid section (66), pressing members (60) are in contact with each other.
