Description

technical field

[0001] The invention relates to a battery arrangement on a vehicle having a battery housing and a protective device for the battery housing, the protective device having at least one energy-absorbing deformation element. The invention also relates to a vehicle, in particular a motor vehicle, having such a battery arrangement. Background technique

[0002] Manufacturers of batteries face the challenge especially with regard to vehicle batteries used as traction batteries, such as HV batteries (HV=Hochvolt, high voltage), to combine the highest safety standards, especially with regard to the crash and breakage safety of the batteries, with as far as possible Combined with small weight. In motor vehicles there are various load situations in which the components surrounding the battery need to protect the battery against intrusion, impact and / or deformation. A typical load case is a pole test, where the battery is pressed onto the pole either statically (squeez...
