A motor vehicle includes several battery elements placed in modules of a first type and modules of a second type. The battery elements in each module of first type are grouped together in an assembly such that the battery elements can shift when exposed to a force, while the assembly is deformable. In each module of second type, the battery elements can shift, when exposed to the force, without being damaged while retaining their shape. The modules of first type are installed in a first region of the motor vehicle of a low stiffness compared to a second region, in which a body of the motor vehicle is designed for force-dissipating deformation in the event of an accident, and the modules of second type are installed in the second region, in which the body of the motor vehicle is designed to retain its shape in the event of an accident.
