Embodiment Construction

[0062] figure 1 The motor vehicle according to the invention is shown in a simplified diagram. The motor vehicle is designed to be electrified and accordingly includes at least one electric traction motor 1 , the drive power of which can be transmitted to driven wheels 2 of the motor vehicle. The motor vehicle can be designed, for example, as a battery electric vehicle (BEV). In this case, it comprises only the one or more electric traction motors 1 and also the traction battery 3 provided for this purpose, which supplies the power required for driving the one or more traction motors 1 , in order to generate driving power. electrical power. Alternatively, the motor vehicle can also be a hybrid vehicle. In this case, the motor vehicle also includes an internal combustion engine (not shown), which is likewise provided at least temporarily to generate drive power, which is transmitted to the driven wheels of the motor vehicle. In this case, the hybrid vehicle can not only be ...

Abstract

The invention relates to a temperature-control element with a sorption material for a battery cell unit, and particularly relates to a temperature-control element (5) with two covering plates (8) which are arranged at a distance from one another and delimit an intermediate space within which a supporting structure (23) is arranged, said supporting structure keeping the covering plates (8) at a distance from one another, wherein the sorption material (7) which makes contact with the covering plates (8) and the supporting structure (23) is additionally accommodated in the intermediate space. A temperature-control element (5) of this kind allows particularly good transfer of thermal energy between the sorption material (7) and the covering plates (8) by way of the supporting structure (23) not only serving to mechanically connect the covering plates (8) and therefore provide structural strength to the temperature-control element (5) but also causing a transfer of thermal energy between the sorption material (7) and the covering plates (8). As a result, the temperature-control element (5) according to the invention is advantageously also suitable for directly controlling the temperature of, for example, one or more battery cells of a battery cell unit, for example of a traction battery of an electrified motor vehicle.

Description

technical field [0001] The invention relates to a temperature control element with an absorber material, in particular for temperature control of battery cells of a motor vehicle. The invention also relates to a battery cell unit with such a temperature control element, a temperature control system with such a battery cell unit, and a motor vehicle with such a temperature control system. Background technique [0002] For the operation of electrified vehicles, such as for example battery electric vehicles (BEV) or hybrid vehicles (HEV or PHEV), powerful (traction) batteries are used in order to supply the electric traction motor of the vehicle with electrical power. Such traction batteries, which may be designed, for example, as lithium-ion batteries, are temperature-sensitive. At relatively low temperatures, they have only a limited storage capacity, which correspondingly has a negative effect on the range of the motor vehicle based on the drive by means of the electric tra...
