Battery case

摘要

The present invention provides a battery case configured by fixing a joined portion where plate sections overlap with each other using a fixation member, and two different types of sealing members are disposed at the joined portion. It is possible to ensure high sealing properties by using sealing members suitable for the respective shapes of portions of the joined portion.

主权项

1. A battery module, comprising:
a plurality of nonaqueous electrolyte cells; and a battery case in which the plurality of nonaqueous electrolyte cells are housed, the battery case including:
a first section including a first opposed surface;a second section provided with a plate-shaped overlap margin on an end of the second portion, the overlap margin including a second opposed surface opposed to the first opposed surface and an end surface being perpendicular to the second opposed surface;a fixation member which attaches the first section to the overlap margin;a first sealing member; anda second sealing member, wherein the first opposed surface is in direct contact with one surface of the first sealing member, wherein the second opposed surface is in direct contact with another surface of the first sealing member, wherein the second sealing member is in direct contact with the first opposed surface and the end surface of the overlap margin, and wherein the first sealing member and the second sealing member are different from each other.
