Description

BACKGROUND OF THE INVENTION

The invention is based on a battery. Subject matter of the present invention is also the use of such.

It is known from the prior art that a battery module has a plurality of individual battery cells that each comprise a positive voltage tap-off and a negative voltage tap-off, wherein in order to connect the plurality of battery cells to one another in an electrically conductive manner in series and/or in parallel the respective voltage tap-offs are connected to one another in an electrically conductive manner and consequently connected together to form the battery module. Battery modules for their part are connected to batteries or to battery systems. On account of a multiplicity of possible different installation spaces in vehicles, variable module sizes are desired in order to be able to make optimal use of the available installation space.

Furthermore, the battery cells of a battery module, such as for example lithium ion battery cells or lithium polymer battery cells, heat up during operation on account of chemical conversion processes and on account of their electrical resistance as battery cells are discharged or charged. In particular, these processes have comparable characteristics in the case of a comparably quick discharge or charging procedure. The greater the capacity of a battery or a battery module, the more heat is produced and consequently the greater the requirements with regard to an efficient temperature control system. In order to increase the safety and reliability of a battery module and also to ensure the efficiency of the battery cells, the battery cells of a battery module need to warm up and cool down in order for them to be able to operate as far as possible in a determined temperature range, so that it is possible by way of example to prevent increased aging behavior or a degradation of the cell chemistry.

However, the battery cells primarily need to cool down.

By way of example, it is possible to control the temperature of the battery, in other words warm up or cool down the battery, by way of a fluid temperature control procedure using a water/glycol mixture. In this case, this mixture is directed through cooling plates that are arranged below the battery module. The cooling plate may be connected in this case to a corresponding component of a cooling circuit.

Prior art is, for example, EP 3 726 612.

SUMMARY OF THE INVENTION

A battery according to the invention offers the advantage that it is possible to adapt the procedure of controlling the temperature of individual components of the battery to their respective requirements. In particular, it is possible by way of a configuration of two temperature control chambers to adapt and optimize the procedure to meet the requirements with regard to controlling the temperature of a plurality of battery cells and of components of the power electronics separately from one another.

For this purpose, a battery is provided in accordance with the invention.

The battery comprises a first housing element and a second housing element. The first housing element and the second housing element jointly form an inner chamber for receiving a battery module. In this case, a plurality of battery cells of the battery module is arranged in the inner chamber. The plurality of battery cells is connected in an electrically conductive manner in series and/or in parallel to one another. Furthermore, a first element of a battery control system is arranged in the inner chamber.

The first housing element forms a first temperature control structure on a face that is remote from the inner chamber. In particular, furthermore the first temperature control structure is formed on a face that is remote from the second housing element.

The second housing element is connected on a face that is remote from the inner chamber, in particular faces that are remote from the first housing element, to a third housing element. In this case, the third housing element receives a second element of the battery control system.

Furthermore, the third housing element forms a second temperature control structure on a face that is turned towards the second housing element. In addition, a second covering element is connected to the third housing element and limits a second temperature control chamber, through which temperature control fluid may flow, in a fluid-tight manner.

In particular, one embodiment in accordance with the invention of the battery offers the advantage that components that convey the temperature control fluid are arranged outside the inner chamber, with the result that in the event of leakages the temperature control fluid may not pass to the battery cells, as a result of which it is possible to increase safety and reliability. In addition, it is possible to cool the individual components in an efficient manner since comparably short thermal paths are produced.

It is advantageous if the first element of the battery control system comprises at least one electrical component of the battery module and/or at least one electronic component of the battery module and if the second element of the battery control system is an electrical voltage convertor, in particular a DC convertor.

It is expedient if the first housing element, the second housing element and/or the third housing element are each embodied as die-cast housings. As a consequence, it is possible to provide a mechanically comparably stable configuration. In addition, it is consequently possible that regions that convey the temperature control fluid may be embodied within the respective die-cast components or are formed by way of connecting a die-cast component and a covering element to one another, with the result that it is possible to forego additional cooling plates, heating elements or temperature control systems.

It is advantageous if the first housing element and the second housing element are connected to one another in a fluid-tight manner. In particular, a first sealing element is arranged between the first housing element and the second housing element.

Consequently, an inner chamber of the battery is provided that is sealed in a fluid-tight manner. In particular, this renders it possible to protect the battery cells, the electrical component and/or the electronic components from external influences.

In accordance with a preferred aspect of the invention, the plurality of battery cells is embodied as prismatic battery cells. Prismatic battery cells comprise hereby a total of six side faces that are arranged in pairs lying opposite one another and parallel to one another. Furthermore, side faces that are arranged adjacent to one another are arranged at right angles with respect to one another. Overall, it is possible to provide a compact battery by way of using prismatically embodied battery cells in a battery in accordance with the invention.

It is preferred if the electrical component of the battery module is a cell connector and/or a cable. Cell connectors are embodied so as to connect voltage tap-offs of battery cells in an electrically conductive manner in series and/or in parallel to one another. Cables are embodied so as to conduct electrical current from one component to another component.

It is preferred if the electronic component of the battery module is a switch, a safety element, a battery control system and/or a resistor.

It is possible by way of arranging the electrical component and/or the electronic component within the inner chamber of the battery to connect the plurality of battery cells of the battery module in an electrically conductive manner in series and/or in parallel to one another and also to open-loop control and closed-loop control the battery module.

In accordance with a preferred aspect of the invention, the at least one electronic component is integrated into a circuit board. This offers the advantage of a comparably compact configuration, the temperature of which is furthermore simple to control.

It is expedient if a first covering element is connected to the first housing element and limits a first temperature control chamber, through which temperature control fluid may flow, in a fluid-tight manner, the covering element being connected to the first housing element in particular in a material-bonded manner, and a second sealing element furthermore being arranged between the first housing element and the covering element.

In this case, the covering element and the first temperature control structure thus in particular jointly form a first temperature control chamber through which temperature control fluid may flow. In this case, it is possible by way of example for the temperature control fluid, which is flowing directly in a thermally conductive manner from one of the first temperature control chambers, to flow around the temperature control structure.

This offers the advantage that the first temperature control structure may be adapted to the requirements with regard to controlling the temperature of the plurality of battery cells that are arranged in the inner chamber. In this case, it is possible to adjust the manner in which the temperature control procedure is adapted independently of the procedure of cooling the electrical component and/or the electronic component and also independently of the procedure of cooling the electrical voltage convertor. By way of example, the first temperature control structure may comprise flow disturbing elements or flow guiding elements that are only arranged at sites where on account of the required temperatures of the plurality of battery cells they may have a positive influence on the temperature control procedure. Furthermore, the remaining regions of the first temperature control chamber may be optimized with respect to the flow and loss of pressure. In particular, it is possible to forego a compromise between controlling the temperature of the plurality of battery cells and of the electrical component and/or the electronic component and also the electrical voltage convertor since it is possible to control the temperature of these components independently of one another.

It is preferred in this case that the covering element is connected to the first housing element in a material-bonded manner. In particular, the covering element may be welded or soldered to the first housing element. Furthermore, a second sealing element may be arranged between the first housing element and the covering element.

It is also preferred for it to be possible if the covering element is formed by the first housing element.

Overall, this offers the advantage that it is possible by way of such a configuration to prevent temperature control fluid from passing into the inner chamber to the plurality of battery cells if defects or leakage sites occur in the first temperature control chamber.

In an advantageous manner, the battery comprises a first connection and a second connection. The first connection is embodied in this case so as to convey the temperature control fluid to the battery and the second connection is embodied in this case so as to discharge the temperature control fluid from the battery.

In particular, the first connection and the second connector form an interface to a motor vehicle.

In accordance with a first aspect, the temperature control fluid may flow through the first temperature control fluid receiving facility and the second temperature control fluid receiving facility in series. In this case, the temperature control fluid flows by way of example initially through the first temperature control fluid receiving facility and subsequently through the second temperature control fluid receiving facility.

In accordance with a second aspect of the invention, the temperature control fluid may flow through the first temperature control fluid receiving facility and the second temperature control fluid receiving facility in parallel. In this case, after it has flowed through the first connection, the temperature control fluid is divided into a first part flow, which flows through the first temperature control fluid receiving facility, and a second part flow which flows through the second temperature control fluid receiving facility. The first part flow and the second part flow are rejoined after they have flowed through the respective temperature control chamber receiving facility and discharged from the battery by means of the second connection. It is possible hereby by way of example to minimize the pressure loss.

In particular, the first housing element and the second housing element and/or the third housing element hereby each comprise a temperature control fluid inlet and a temperature control fluid outlet. The respective temperature control fluid inlet is used so as to allow temperature control fluid into the first flow chamber or the second flow chamber and the respective temperature control fluid outlet is used so as to allow temperature control fluid to flow out from the first flow chamber or the second flow chamber. Furthermore, a temperature control fluid inlet and a temperature control fluid outlet may be connected to one another in a fluid-conducting manner with the result that temperature control fluids may flow between the first flow chamber and the second flow chamber or conversely.

By way of example, the temperature control fluid inlet of the second housing element and/or of the third housing element form the first connection of the battery with the result that temperature control fluid may flow into the second flow chamber. Furthermore, by way of example, the temperature control fluid outlet of the second housing element and/or of the third housing element may be connected to the temperature control fluid inlet of the first housing element in a fluid-conducting manner with the result that temperature control fluid may first flow through the second flow chamber and subsequently through the first flow chamber, in other words a series through-flow connection is formed. In addition, by way of example, the temperature control fluid outlet of the first housing element may form the second connection of the battery with the result that hereby temperature control fluid may exit the first flow chamber.

By way of example, the temperature control fluid inlet of the first housing element may form the first connection of the battery with the result that hereby temperature control fluid may flow into the first flow chamber. Furthermore, by way of example, the temperature control fluid outlet of the first housing element may be connected in a fluid-conducting manner to the temperature control fluid inlet of the second housing element and/or of the third housing element with the result that temperature control fluid may first flow through the first flow chamber and subsequently through the second flow chamber, in other words a series through-flow connection is formed. In addition, by way of example, the temperature control fluid outlet of the second housing element and/or of the third housing element may form the second connection of the battery with the result that hereby temperature control fluid may exit the second flow chamber.

It is preferred that the first temperature control structure, the second temperature control structure and/or the third temperature control structure are each embodied as flow guiding elements, as flow disturbing elements or as flow limiting elements.

In particular, the first temperature control structure, the second temperature control structure and/or the third temperature control structure may each be formed by the corresponding die-cast housing.

At this point, flow guiding elements are to be understood to be such elements that are arranged within a respective temperature control chamber and that are used to deflect a flow without creating a comparable increase in turbulence.

At this point, flow disturbing elements are to be understood to be such elements that are arranged within a respective temperature control chamber and that are used to increase the turbulence of a flow, in particular to create a transition from a laminar flow to a turbulent flow in order however to improve the manner in which heat is discharged.

At this point, flow limiting elements are to be understood to be such elements that mechanically limit the respective temperature control chamber.

In particular, it is to be noted that for this purpose the second temperature control structure and the third temperature control structure jointly may influence a temperature control fluid that is flowing through the second flow chamber.

It is of advantage if the plurality of battery cells is connected in a fluid-conducting manner to a first inner face of the inner chamber, wherein the first inner face is arranged directly adjacent to the first temperature control structure. In particular, in so doing a first thermal compensating element, such as by way of example a thermally conductive adhesive material, may be arranged between the plurality of battery cells and the inner face.

It is also advantageous if the first element of the battery control system is connected to a second inner face of the inner chamber in a thermally conductive manner, wherein the second inner face is arranged directly adjacent to the third housing element. In particular, in so doing, for example a second thermal compensating element, such as by way of example a thermally conductive adhesive material or a so-called thermal interface material (TIM), may be arranged between the electrical component and/or the electronic component.

By way of example, it is possible by way of connecting a circuit board that comprises the electronic component to the second housing element, by way of example by means of screws, to form a reliable thermal conductive path. Overall, a comparably short thermal path is hereby created between a temperature control fluid, which is flowing through the second temperature control chamber, and the circuit board having a consequently comparably low thermal resistance.

Furthermore, it is advantageous if the second element of the battery control system is connected in a thermally conductive manner to an inner face of the third housing element, wherein this inner face is arranged directly adjacent to the second housing element. In so doing, for example, furthermore a third thermal compensating material, such as by way of example a thermally conductive adhesive material or a so-called thermal interface material (TIM), may be arranged between the electrical voltage convertor and the inner face of the third housing element. It is possible by way of connecting, such as by way of example by means of screws, the electrical voltage convertor to the third housing element to form a reliable thermal conductive path. Overall, a comparably short thermal path is hereby created between a temperature control fluid, which is flowing through the second temperature control chamber, and the electrical voltage convertor having a consequently comparably low thermal resistance.

Subject matter of the present invention is also the use of an above-described battery in accordance with the invention so as to control the temperature and in particular to cool the plurality of battery cells, the first element of the battery control system and the second element of the battery control system, in particular the electrical component and/or the electronic component and/or the electrical voltage convertor, wherein a temperature control fluid, which is in the form of a temperature control liquid or a temperature control gas, flows around the first temperature control structure or wherein the temperature control fluid that is in the form of a temperature control liquid flows around the second temperature control structure.
