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 ballistic resistant case for a secondary battery having a rectangular metal case (160) with a panel (160p) connected to the bottom wall and the side walls to divide the internal space of the case into cell pack receiving bays (160b). A bus bar (170) extends from the front wall, across the top of the panel, to the rear wall. A connector (162, 170f, 180a) secures the cover (180) to the panel (160p) with the bus bar (170) sandwiched therebetween. The bus bar (170) reinforces a central portion of the cover (180) and prevents the panel (160p) and the walls from deflecting to provide ballistic protection for the cell packs (24).

Provided is a battery pack including: an exterior case; a cylindrical battery cell including a positive electrode terminal part at one end and a negative electrode terminal part at the other end; and a metal plate connected to the positive electrode terminal part or the negative electrode terminal part, where the battery cell has a peripheral protrusion around the positive electrode terminal part or the negative electrode terminal part, the metal plate has a protrusion that faces the peripheral protrusion, and the protrusion is disposed in close contact with the whole periphery of the peripheral protrusion, with a first insulating part interposed therebetween.

A battery pack having a battery housing that defines a cavity for receiving a plurality of battery cells. The battery pack cavity is sealed from the air outside the battery pack housing to prevent water and other contaminants from reaching the plurality of battery cells. The battery pack may include a sealing material to create a seal between an upper housing and a lower housing of the battery housing. The battery pack also include a sealing material to create a seal around a terminal block of the battery pack.

A power system includes a battery module and a battery ECU. The battery module includes multiple battery stacks. Each of multiple battery stacks includes multiple battery cells, multiple detectors which independently detect physical values of the multiple battery cells, respectively, and multiple individual communicators which wirelessly output detection results of the multiple detectors. Each of the multiple individual communicators communicates a radio signal wirelessly to and from a general monitor. The multiple battery stacks and the general monitor are accommodated in a storage space in a housing having electromagnetic shielding performance. A shield is also accommodated in the storage space while facing a communication hole formed on the housing.
