Abstract

A battery box for a motor vehicle for receiving battery cells has a structural frame with at least two structural components joined to one another at the end face. Each structural component has at least one profile segment that is partially hollow and has a substantially L-shaped cross section. A reinforcement element for absorbing collision energy in the event of a collision is arranged within at least one of the profile segments. The reinforcement element is a molded part having a plurality of open cells, which are arranged adjacent to one another and with their longitudinal extent substantially parallel to one another. When the battery box is mounted in the motor vehicle, the open cells are oriented with their longitudinal extent substantially parallel to the transverse direction of the vehicle.
