Offenbarung der ErfindungDisclosure of the invention

Der Erfindung liegt die Aufgabe zugrunde, den Elektronikbereich einer gattungsmäßigen Traktionsbatterie besonders wirksam und auf vollständig integrierte Weise zu kühlen.The invention is based on the objective of cooling the electronics area of a generic traction battery in a particularly effective and fully integrated manner.

Die Erfindung stellt eine Traktionsbatterie für ein elektrisch betriebenes Fahrzeug sowie ein mit einer Traktionsbatterie ausgestattetes Fahrzeug gemäß den unabhängigen Ansprüchen bereit.The invention provides a traction battery for an electrically powered vehicle and a vehicle equipped with a traction battery according to the independent claims.

Ein Vorzug dieser Lösung liegt darin, dass die Elektronik der HV-Batterie durch die Kühlung der Batteriemodule mitgekühlt wird.One advantage of this solution is that the electronics of the HV battery are cooled along with the cooling of the battery modules.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Patentansprüchen angegeben. So kann die Traktionsbatterie einen Auslasskanal zum Abführen des Kühlmittels umfassen, welcher einerseits mit dem Modulbereich und andererseits mit dem Elektronikbereich fluidtechnisch verbunden ist. Räumlich abgetrennt vom Modulbereich des Batteriesystems erhält dieser Elektronikbereich sein Kühlmedium so dennoch durch die gleichen Kühlanschlussbereiche.Further advantageous embodiments of the invention are specified in the dependent claims. For example, the traction battery can include an outlet channel for discharging the coolant, which is fluidically connected to the module area on one side and to the electronics area on the other. Spatially separated from the module area of the battery system, this electronics area nevertheless receives its cooling medium through the same cooling connection areas.

In einer bevorzugten Ausführungsform weist die Traktionsbatterie eine geeignete Gehäusekontur auf, um das durch den Einlasskanal zugeführte Kühlmittel um den Elektronikbereich zu dem Auslasskanal zu lenken. So wird eine Gegenstromkühlung realisiert.In a preferred embodiment, the traction battery has a suitable housing contour to direct the coolant supplied through the inlet channel around the electronics area to the outlet channel. This achieves counterflow cooling.

Vorzugsweise enthält der Auslasskanal eine Drosselscheibe, insbesondere eine Platte mit definierten Bohrungen, zum Drosseln des abgeführten Kühlmittels. Die Abflussmenge kann durch eine solche Drosselscheibe im Auslasskanal geregelt werden.Preferably, the outlet channel includes a throttle disc, in particular a plate with defined bores, for throttling the discharged coolant. The flow rate can be regulated by such a throttle disc in the outlet channel.

Der Elektronikbereich umfasst gemäß einer Variante eine zwischen dem Einlasskanal und dem Auslasskanal angeordnete Kühlplatte, welche fluiddicht und wärmeleitfähig ist. Die Elektronik dient mit ihrer zusätzlichen Kühlplatte somit auch zur Trennung der durch den Einlass und Auslass definierten Strömungspfade und unterstützt somit die besagte Gegenstromkühlung.According to one variant, the electronics section includes a cooling plate positioned between the inlet and outlet channels, which is fluid-tight and thermally conductive. With its additional cooling plate, the electronics also serve to separate the flow paths defined by the inlet and outlet, thus supporting the aforementioned counterflow cooling.

Die Traktionsbatterie kann ferner eine zwischen dem Modulbereich und dem Elektronikbereich angeordnete Trägerwand umfassen, in welche der Auslasskanal integriert ist. Auf diesem Weg ergibt sich eine vollständig integrierte Elektronik-Kühlung.The traction battery can further include a support wall located between the module area and the electronics area, into which the exhaust channel is integrated. This results in fully integrated electronics cooling.

In einer weiteren vorteilhaften Ausgestaltung enthält die Trägerwand Epoxidharz oder Glasfaser, vorzugsweise vereint in einem Verbundwerkstoff. Eine derartige Materialwahl unterstützt die tragende Funktion der Wand in erheblichem Maße.In a further advantageous embodiment, the supporting wall contains epoxy resin or glass fiber, preferably combined in a composite material. Such a choice of material significantly enhances the load-bearing function of the wall.

Ausführungsformen der ErfindungEmbodiments of the invention

1 illustriert die erfindungsgemäß vorgesehenen Strömungspfade des Kühlmittels durch die Traktionsbatterie 10 eines elektrisch betriebenen Fahrzeuges. Die Traktionsbatterie 10 weist einen zeichnerisch lediglich angedeuteten Modulbereich 11 und einen von dem Modulbereich 11 räumlich getrennten Elektronikbereich 12 auf. Wie die Detailansicht gemäß 2 erkennen lässt, ist ein als nichttragendes Formteil ausgeführter Einlasskanal 13 gehäuseseitig in die Traktionsbatterie 10 integriert, der symmetrisch einerseits in den Modulbereich 11 und andererseits in den Elektronikbereich 12 verzweigt. 1 Figure 1 illustrates the flow paths of the coolant through the traction battery 10 of an electrically powered vehicle as provided for in the invention. The traction battery 10 has a module area 11, which is only indicated in the drawing, and an electronics area 12 that is spatially separated from the module area 11. As shown in the detailed view according to Figure 1, the flow paths of the coolant through the traction battery 10 are shown in the drawing. 2 As can be seen, an inlet channel 13 designed as a non-load-bearing molded part is integrated into the traction battery 10 on the housing side, which branches symmetrically on the one hand into the module area 11 and on the other hand into the electronics area 12.

3 beleuchtet anhand einer perspektivischen Darstellung die den Modulbereich 11 von dem Elektronikbereich 12 räumlich trennende, aus glasfaserverstärktem Epoxidharz gefertigte Trägerwand 18 der Elektronik. In diese Trägerwand 18 ist ein einerseits mit dem Modulbereich 11 und andererseits mit dem Elektronikbereich 12 fluidtechnisch verbundener, ebenfalls als nichttragendes Formteil ausgeführter Auslasskanal 15 integriert. Der Auslasskanal 15 wiederum enthält zum Drosseln des abgeführten Kühlmittels eine Drosselscheibe 16 in Gestalt einer Platte mit definierten Bohrungen. 4 zeigt diese Drosselscheibe 16 in ihren Einzelheiten. 3 The diagram illustrates, using a perspective view, the support wall 18 of the electronics, made of glass fiber reinforced epoxy resin, which spatially separates the module area 11 from the electronics area 12. An outlet channel 15, also designed as a non-load-bearing molded part, is integrated into this support wall 18. This outlet channel 15 is fluidically connected to both the module area 11 and the electronics area 12. The outlet channel 15, in turn, contains a throttle plate 16 with defined bores for throttling the discharged coolant. 4 This throttle disc 16 shows its details.

Im rechten unteren Bereich der 1 weist die Traktionsbatterie 10 eine geeignete Gehäusekontur 14 auf, um das durch den Einlasskanal 13 zugeführte Kühlmittel um den Elektronikbereich 12 zu dem Auslasskanal 15 zu lenken. Nach der Umlenkung passiert das Kühlmittel rückseitig eine zwischen dem Einlasskanal 13 und dem Auslasskanal 15 im Elektronikbereich 12 angeordnete Kühlplatte 17. Diese ist zwar fluiddicht, jedoch wärmeleitfähig ausgeführt, sodass die Elektronik nach dem Gegenstromprinzip von beiden Seiten gekühlt wird.In the lower right area of the 1 The traction battery 10 has a suitable housing contour 14 to direct the coolant supplied through the inlet channel 13 around the electronics area 12 to the outlet channel 15. After being deflected, the coolant passes behind a cooling plate 17 located between the inlet channel 13 and the outlet channel 15 in the electronics area 12. This cooling plate is fluid-tight but thermally conductive, so that the electronics are cooled from both sides according to the counterflow principle.
