An impact detection device for a traction battery of a motor vehicle includes at least one air-filled chamber formed on an underbody element for the traction battery. An air-filled chamber is at least laterally sealed to outside and defined by a sealing material. A pressure hose and an introduction element for the pressure hose can be provided, wherein the air-filled chamber can be coupled to a pressure sensor through the pressure hose, and the introduction element can be attached to the underbody element and formed to couple the pressure hose to the air-filled chamber through the sealing material in a set position. The introduction element can be embedded by the sealing material which seals the air-filled chamber.

A battery module includes a battery cell assembly constituted by stacking a plurality of battery cells, an end plate disposed adjacent to one end of the battery cell assembly, and a shock-absorbing member interposed between the one end of the battery cell assembly and the end plate, wherein the shock-absorbing member is woven fabric or non-woven fabric formed of a plurality of fibers.

A system for reducing the likelihood of a battery short during a collision of a vehicle includes a metallic structure coupled to a portion of the vehicle. The system further includes a battery located proximate to the metallic structure and having a positive terminal. The system further includes an insulator coupled to the metallic structure such that it is located between the metallic structure and the positive terminal of the battery and configured to resist contact between the metallic structure and the positive terminal of the battery in response to the collision of the vehicle.

To provide a flexible, highly reliable power storage device or light-emitting device. The device includes a battery unit or a light-emitting unit and a member with rubber elasticity. The battery unit includes a secondary battery. The light-emitting unit includes a light-emitting element. The member with rubber elasticity is provided with a first projection and a second projection. The first projection and the second projection are arranged on a first surface of the battery unit or the light-emitting unit. The first projection and the second projection come in contact with each other when the power storage device is bent such that the first surface of the battery unit faces inward.
