1. An electrical energy storage apparatus for a motor vehicle, the electrical energy storage apparatus comprising:
a plurality of components belonging to the electrical energy storage apparatus;
a housing, on and/or in which the components belonging to the electrical energy storage apparatus are arranged; and
a distribution network configured to distribute at least one of materials, energy and information, which is arranged in the housing and which has at least one line, which belongs to the electrical energy storage apparatus and is coupled to at least one of the components belonging to the electrical energy storage apparatus so as to transmit the at least one of the materials, the energy and the information;
wherein the distribution network includes at least one line, separate from the electrical energy storage apparatus, for transmitting the at least one of the materials, the energy and the information between the components, which are separate from the electrical energy storage apparatus, of the motor vehicle outside of the housing;
wherein the distribution network includes a communication network for transmitting information including monitoring signals or control signals;
wherein the communication network is a waveguide that is configured to transmit acoustic and/or optical signals as the monitoring signals or the control signals; and
wherein the waveguide is a single-piece molded part that has a solid body including first surface structures for signal in-coupling and signal out-coupling for the components belonging to the electrical energy storage apparatus, and second surface structures for signal in-coupling and signal out-coupling for the components separate from the electrical energy storage apparatus.
