Abstract: An underbody of an electrically driven motor vehicle, with a vehicle supporting structure, which is bounded laterally in a transverse direction of the vehicle by two vehicle sills between which a multiplicity of battery modules is arranged, which battery modules are assigned a battery supporting structure and at least one battery temperature control device, and with supply and removal devices for a temperature control medium. The supply and removal devices for the temperature control medium are arranged in the region of the vehicle sills.

Abstract: A thermoelectric arrangement for use in a cooling system (4, 6) of a motor vehicle has a thermocouple (8) with a first, heat-outputting thermal element (10), a second, heat-absorbing thermal element (12) and a conductor element (14) through which current flows. At least two cooling circuits (16, 18, 20) are provided. The first thermal element (10) is arranged in at least one cooling circuit (16, 18, 20), and the second thermal element (12) is arranged in at least one heating circuit (48). The first thermal element (10) is arranged in a first connecting line (22) that is connected fluidically to the respective cooling circuits (16, 18, 20) via valve arrangements (24, 26; 28, 30; 32, 34) on the input and output sides of the first thermal element (10). A cooling system having such a thermoelectric arrangement also is described.

Abstract: An arrangement of a thermoelectric heat pump in at least one first fluid circuit, one second fluid circuit and one third fluid circuit is provided for a motor vehicle. The arrangement has a first heat exchanger provided for exchange of heat between a fluid of the first fluid circuit and a fluid of a third fluid circuit, and a second heat exchanger is provided for the exchange of heat between a fluid of the second fluid circuit and the fluid of the third fluid circuit. In each case one thermoelectric element is arranged between the heat exchange regions of the first heat exchanger and between the heat exchange regions of the second heat exchanger.
