A motor vehicle rear end has left and right longitudinal beams () forming load-bearing structures of the vehicle, and a receiving housing () is between the left and right longitudinal beams () for accommodating a traction battery. The receiving housing () has left and right side walls () and a central wall () running in a forward direction of travel. An impact profile () is connected to the longitudinal beams () at the level of the receiving housing () and absorbs impact energy in the event of a rear-end crash. The impact profile () has a left and right predetermined buckling points () that enable the impact profile () to buckle toward the receiving housing () in a rear-end crash. The impact profile () that buckles in a rear-end crash strikes the receiving housing () along the longitudinal extent of the central wall ().

Motor vehicle rear end

A motor vehicle rear () has left and right longitudinal members () forming a supporting structure of the motor vehicle. A receiving housing () is arranged between the longitudinal members () for receiving a traction battery. The receiving housing () has a left and right side walls () running in the forward direction of travel. A back wall () is connected to the left and right side walls () and running transverse to the forward direction of travel. An impact profile () is connected to the left and right longitudinal members () and absorbs impact energy in the event of a rear crash. Left and right reinforcing elements () connect the impact profile () to the respective left and right side walls () for reinforcing the impact profile () and conducting away some of the impact energy into the left and right side walls ().

Motor vehicle rear

A protective housing for a battery in a motor vehicle includes two transverse walls and two longitudinal walls, which together form a lateral enclosure for a battery receptacle chamber. The protective housing is fastened to at least one longitudinal girder of the vehicle in the installed state in an installation chamber of the vehicle. The transverse walls and the longitudinal walls are each formed by separate components, which are assembled into the enclosure. The installation chamber is located between two longitudinal girders of the vehicle chamber, and the enclosure is fastened to both longitudinal girders.
