Heating and cooling device for a battery

A battery arrangement for a motor vehicle, comprising:

• a battery;
• and
• a heating and cooling device thermally coupled to the battery, the heating and cooling device including:
• an electrically conductive base plate coupled to the battery, the base plate including at least one fluid path for flow of a coolant;
• a carrier plate of an electrically non-conductive material and configured to receive at least one heating element, the carrier plate electrically connected with the electrically conductive base plate;
• an electrically conductive cover plate connected electrically with the at least one electric heating element;
• wherein the base plate, the carrier plate and the cover plate are arranged stacked one on top of the other along a stacking direction, and wherein the carrier plate is sandwiched between the base plate and the cover plate in the stacking direction.

A motor vehicle, comprising:

• at least one battery arrangement including a battery thermally coupled to a heating and cooling device, the heating and cooling device including:
• an electrically conductive base plate connected to the battery, the base plate including at least one fluid path for flow of a coolant, wherein the at least one fluid path includes at least two flat tubes arranged spaced apart from one another relative to a transverse direction of the base plate, the at least two flat tubes extending at least partially along a longitudinal direction of the base plate;
• a carrier plate of an electrically non-conductive material connected electrically with the base plate, the carrier plate including at least two through-openings;
• at least two electric heating elements disposed in the at least two through-openings of the carrier plate;
• an electrically conductive cover plate connected electrically with the at least two electric heating elements;
• wherein the base plate, the carrier plate and the cover plate are arranged stacked one on top of the other along a stacking direction, and the carrier plate is sandwiched between the base plate and the cover plate in the stacking direction;
• and
• wherein the cover plate lies against a first side of the at least two electric heating elements and the base plate lies against a second side of the at least two electric heating elements opposite the first side with respect to the stacking direction.
