The invention relates to battery modules, battery devices and to methods for producing a battery module.

A power storage module includes a plurality of power storage devices (for example, secondary batteries) arranged side by side and a holder having a container that contains the plurality of power storage devices. The holder includes a first holder and a second holder. Each of the plurality of power storage devices includes a first end and a second end. The first end is contained in the first holder and the second end is contained in the second holder. In the holder, resin is disposed in at least one of a space between the plurality of power storage devices and a space between the power storage device and the holder. The holder is provided with a gap defined by at least the resin and the holder and communicating with the outside of the holder.

A high strength, light weight battery containment construct for containing and protecting energy cells and providing impact, fire, and fluid penetration resistance includes a first housing portion, a second housing portion, and a joiner clip configured to hold the first housing portion and second housing portion together. The first housing portion has a first body and a first flange extending from the first body. The second housing portion has a second body and a second flange extending from the second body. The second flange is configured to engage the first flange such that the first body of the first housing portion and the second body of the second housing portion define a cavity therebetween. The joiner clip is configured with a C-shaped cross section to engage the first flange and the second flange to join the first housing portion to the second housing portion.

A battery apparatus includes a main body having a first connection portion and a second connection portion and an output end protective support having a first fitting connection portion and a second fitting connection portion. The first connection portion is engaged with the first fitting connection portion, and the second connection portion is engaged with the second fitting connection portion. The first and second fitting connection portions are not disposed on a same side of the output end protective support. The first fitting connection portion includes a rigid piece or a plastic piece, and at least one of the second connection portion and the second fitting connection portion includes an elastic piece. One end of the output end protective support is elastically engaged with the main body and the other end of the output end protective support has the rigid or plastic piece and is engaged with the battery apparatus.

A power storage device includes a plurality of power storage modules, a case, a monitoring unit, and an attachment bracket. Each of the power storage modules includes a plurality of power storage cells. The power storage modules are arranged side by side in an orthogonal direction. The monitoring unit is disposed between the case and the power storage modules. The monitoring unit includes a housing made of resin. The case includes a partition wall made of metal and an outer-side covering portion made of metal. The partition wall includes a lateral-side covering portion. The attachment bracket includes an upper-side covering portion that covers an upper side of the monitoring unit.
