Temperature-control device for an energy store

A motor vehicle, comprising:

• an energy store and a temperature-control device for temperature-controlling the energy store, the temperature-control device including:
• a first circuit including a first heat transfer unit and the energy store arranged in the first circuit and connected to one another in a heat-transferring manner via a first heat transfer medium;
• a second circuit including a second heat transfer unit and the first heat transfer unit arranged in the second circuit and connected to one another in a heat-transferring manner via a second heat transfer medium;
• wherein in at least one of at least one line of the first circuit and at least one line of the second circuit at least one of a predetermined breaking point and a predetermined bending point is arranged, wherein the at least one of the predetermined breaking point and the predetermined bending point upon a predefined force effect interrupts a flow of at least one of the first heat transfer medium and the second heat transfer medium in the respectively associated circuit;
• and
• wherein the predetermined breaking point provides a break point with a reduced cross section relative to the reminder of the at least one line, and wherein the predetermined bending point provides a bend in a straight portion of the at least one line.
