Abstract: A thermoelectric temperature-control unit may include a first contact plate, a second contact plate, and at least one plate-shaped thermoelectric transducer. The thermoelectric transducer may have a first transducer side and a second transducer side facing away from the first transducer side. The thermoelectric transducer may be coupled to the first contact plate on the first transducer side and coupled to the second contact plate on the second transducer side. At least one of the first contact plate and the second contact plate may include a coupling zone on a respective inner side. A circumference of the coupling zone may be surrounded by a groove. A heat-conducting material may be arranged in the groove and along the coupling zone, and may directly contact the i) respective inner side and ii) one of the first transducer side and the second transducer side facing the respective inner side.

Abstract: A temperature control device for tempering of a battery may include a cooling device configured to be flowed through by a coolant for cooling the battery, an electric heating module configured to heat the battery and a heat transmission component configured to thermally couple the cooling device and the electric heating module to the battery. The battery may be temperature-controlled. The heat transmission component may have a recess. An electric heating module may be received in the recess and may be secured to the heat transmission component via an adhesive connection. The recess may be arranged on a first side comprising one of an upper side or underside of the heat transmission component. The electric heating module may be received in the recess and may terminate flush with the first side. The cooling device may lie in a planar manner against the first side of the heat transmission component.

Abstract: The invention relates to a heat exchanger for a battery unit, comprising coolant-conducting tubes which end at both sides in in each case one collector, wherein each collector is connected to at least one tube and a potential equalization element for electrical potential equalization connects at least one collector to a housing of the battery. To produce potential equalization between the heat exchanger and a battery housing in as inexpensive a manner as possible, the potential equalization element and the collector are formed in one piece.

Abstract: The invention relates to a heat exchanger for a battery unit, comprising coolant-conducting tubes (3b) which end at both sides in in each case one collector (3a, 3c), wherein each collector (3a, 3c) is connected to at least one tube (3b) and a potential equalization element for electrical potential equalization connects at least one collector (3a, 3c) to a housing (5) of the battery (2). To produce potential equalization between the heat exchanger and a battery housing in as inexpensive a manner as possible, the potential equalization element (14, 15, 17, 23, 24) and the collector (3a, 3c) are formed in one piece.
