Abstract: A motor vehicle battery includes a battery housing. The battery housing has a housing interior bounded in sections by a housing frame and a housing base. The motor vehicle battery further includes a plurality of battery modules arranged in the housing interior. The motor vehicle battery further includes at least one first cooling duct. The at least one first cooling duct is formed in the region of the housing base, for cooling the battery modules from a first side. The housing interior is bounded by a housing cover or by a housing lid opposite the housing base.

Abstract: An underbody unit for a motor vehicle body has a floor body (12) connectable to the motor vehicle body for dissipating static and/or dynamic loads. Reinforcing ribs (14) protrude up from the floor body (12). The reinforcing ribs (14) together with the floor body (12) delimit receiving pockets (16) for receiving battery cell units (18) of a traction battery for driving the motor vehicle. First and second connections (34, 36) supply and remove a refrigerating agent for cooling the floor body (12). The battery cell units (18) are above the floor body (12) and can be inserted into the underbody unit (10). Thus, the underbody unit (10), the reinforcing ribs (14) and the connections (34, 36) for the refrigerating agent define a supporting plate that can support the heavy battery cell units (18), form armor plating for protection and a heat exchanger for active and/or passive cooling.

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.

The reinforcing ribs (14) together with the floor body (12) delimit receiving pockets (16) for receiving battery cell units (18) of a traction battery for driving the motor vehicle. First and second connections (34, 36) supply and remove a liquid cooling medium for cooling the floor body (12). The battery cell units (18) are above the floor body (12) and can be inserted into the underbody unit (10). Thus, the underbody unit (10), the reinforcing ribs (14) and the connections (34, 36) for the coolant define a supporting plate that can support the heavy battery cell units (18), form armor plating for protection and a heat exchanger for active and/or passive cooling.

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.

Abstract: In a method and apparatus for the operation of a vehicle having a battery with a plurality of series or parallel connected individual cells, a coolant flows through the respective cell housings and/or a battery housing that encloses the entire battery. The coolant is delivered within a coolant circuit by a pump unit, and is thermally coupled with a refrigerant circuit through a heat exchanger. A refrigeration compressor placed in the refrigerant circuit is thermally coupled with the coolant circuit through the heat exchanger, depending on a current ambient temperature and/or a current speed of the vehicle. The speed of the refrigeration compressor may be regulated depending on the current ambient temperature and/or the current speed of the vehicle.
