Method for integrating a high-voltage accumulator into a support structure of a motor vehicle, and motor vehicle

The invention relates to a method for integrating a high-voltage accumulator (2) having at least one accumulator module (4) into a support structure (6) of a motor vehicle, wherein the following stepsare performed: providing a housing part (5), which has a base plate (22) and a frame-like edge (23) extending around the base plate (22); arranging the at least one accumulator module (4) on the housing part (5) and/or on the support structure (6); arranging the edge (23) of the housing part (6) below and on a frame structure (7) formed of supports (11, 12) of the support structure (6); and fastening the housing part (5) to the support structure (6), an accumulator housing (16) for the at least one accumulator module (4) thus being formed, a housing interior of the accumulator housing (16) being delimited by a bottom part (8) of the support structure (6), which bottom part covers the frame structure (7) toward a passenger compartment of the motor vehicle, and by the housing part (5) and the frame structure (7).
