1. A method for arranging a high-voltage accumulator having a plurality of battery modules on a support structure of a motor vehicle, comprising:
arranging the battery modules on, and fastened to, a base plate;
fastening the base plate to a bottom plate of the support structure of the motor vehicle, whereby the base plate and the bottom plate provide an accumulator housing which delimits an accumulator interior in which the plurality of battery modules are accommodated; and
mechanically connecting at least one connection field, via which the high-voltage accumulator is electrically and/or fluidically connectable to the motor vehicle, to the support structure, wherein
the at least one connection field with the base plate is brought toward the support structure and is placed against and fastened to the support structure on an inner side of the support structure facing the accumulator interior.
