The present disclosure relates to a deformation device for a motor vehicle. The deformation device comprises a support structure and a charging module which is fixed to the support structure at two mutually spaced connecting elements. The support structure comprises a target bend region which is arranged between the at least two connecting elements. The support structure is designed to bend, at least in regions, at the target bend region in the event of accident-related deformation of said support structure, and as a result press onto the charging module at the target bend region, and release a first connection between the charging module and the support structure formed via a first connecting element of the at least two connecting elements. A further aspect of the present disclosure relates to a motor vehicle having the deformation device.
