Abstract
Description
Die Erfindung betrifft eine Batterieeinheit in einem Hybrid-Fahrzeug und ein Verfahren zur Kühlung einer Batterieeinheit. In Hybrid-Fahrzeugen müssen zusätzlich zu einem Kraftstofftank elektrische Energiespeicher zur Energieversorgung eines Elektromotors angeordnet werden. Diese Energiespeicher sind oftmals als so genannte Batterieeinheiten oder Batteriepakete ausgebildet, die mehrere Batterien oder Batteriezellen enthalten. In der Regel weisen diese Batterieeinheiten im Vergleich zu existierenden Kraftstofftanks sehr hohe Bauraumanforderungen und ein höheres Gewicht auf. Bevorzugt werden diese Batterieeinheiten daher in einem Unterflurbereich des Hybrid-Fahrzeugs angeordnet, um die Lage des Schwerpunkts des Hybrid-Fahrzeugs vorteilhaft zu beeinflussen. Teilweise werden die Batterieeinheiten unter einer Hintersitzanlage des Hybrid-Fahrzeugs und/oder in einer Reserveradmulde angeordnet. Der Bereich unter der Hintersitzanlage wird in konventionellen Hybrid-Fahrzeugen jedoch auch für die Anordnung eines Kraftstofftanks und einer Abgasanlage genutzt. Die Abgasanlage führt dabei Abgase, die beim Betrieb einer Verbrennungskraftmaschine des Hybrid-Fahrzeugs entstehen, aus dem Fahrzeug ab, beispielsweise über ein so genanntes Abgas- oder Auspuffrohr.The The invention relates to a battery unit in a hybrid vehicle and a method for cooling a battery unit. In Hybrid vehicles must be in addition to a fuel tank electrical energy storage for the power supply of an electric motor to be ordered. These energy stores are often called so-called Battery units or battery packs are formed, which have multiple batteries or battery cells. In general, these battery units very high space requirements compared to existing fuel tanks and a higher weight. These battery units are preferred therefore arranged in an underfloor area of the hybrid vehicle, advantageous to the location of the center of gravity of the hybrid vehicle influence. Sometimes the battery units are under one Rear seat system of the hybrid vehicle and / or arranged in a spare wheel well. The area under the rear seat system will be in conventional hybrid vehicles but also for the arrangement of a fuel tank and used an exhaust system. The exhaust system leads here Exhaust gases during operation of an internal combustion engine of the hybrid vehicle emerge from the vehicle, for example via a so-called exhaust or exhaust pipe.
Durch den Kraftstofftank und/oder die Abgasanlage steht wenig Bauraum für eine zusätzliche Batterieeinheit zur Verfügung. Dies stellt insbesondere dann ein Problem dar, wenn Batterieeinheiten in Fahrzeuge nachgerüstet werden sollen. Weiterhin wird durch die Abgasanlage im Betrieb Wärme erzeugt, die sich nachteilig auf den Betrieb der Batterieeinheit auswirkt.By the fuel tank and / or the exhaust system is little space for an additional battery unit available. This is especially a problem when battery units to be retrofitted in vehicles. Continue heat generated by the exhaust system during operation, which is adversely affects the operation of the battery unit.
Ein weiteres Problem beim Einbringen einer Batterieeinheit unter die Hintersitzanlage resultiert aus der Anordnung bzw. dem Verlauf des Abgasrohrs. Es existieren Lösungen, bei denen das Abgasrohr um eine zusätzlich eingebrachte Batterieeinheit herumgeführt wird. Hierdurch entstehen jedoch deutliche Druckverluste im Abgasrohr, die zu einer Leistungsminderung der Antriebsleistung und zu einem Mehrverbrauch von Kraftstoff führen.One Another problem when inserting a battery unit under the Hintersitzanlage results from the arrangement or the course of the Exhaust pipe. There are solutions in which the exhaust pipe around an additionally introduced battery unit becomes. However, this causes significant pressure losses in the exhaust pipe, to a reduction in performance of the drive power and an increased consumption lead from fuel.
Eine
weitere Lösung besteht darin, eine Batterieeinheit in zwei
baulich getrennte Batterieeinheiten aufzuteilen, wobei das Abgasrohr
zwischen den baulich getrennten Batterieeinheiten hindurchgeführt wird.
Die
Es stellt sich daher das technische Problem, eine Batterieeinheit und ein Fahrzeug zu schaffen, welches sich hinsichtlich der Bauraumanforderungen optimal in ein existierendes Hybrid-Fahrzeug integriert, wobei gleichzeitig die Abgasführung durch ein Abgasrohr nicht negativ beeinflusst wird. Weiterhin stellt sich das technische Problem, ein Verfahren zur Kühlung einer solchen Batterieeinheit zu schaffen, um eine optimale Energieversorgung durch die Batterieeinheit und eine lange Lebensdauer der Batterieeinheit zu gewährleisten.It Therefore, the technical problem arises, a battery unit and to create a vehicle which is optimal in terms of space requirements integrated into an existing hybrid vehicle, while at the same time the exhaust system through an exhaust pipe is not adversely affected becomes. Furthermore, there is the technical problem, a method to provide for cooling such a battery unit to an optimal power supply through the battery unit and a to ensure long life of the battery unit.
Die
Lösung des technischen Problems ergibt sich aus den Merkmalen
der Ansprüche 1, 7 und 9. Weitere vorteilhafte Ausgestaltungen
der Erfindung ergeben sich aus den Merkmalen der Unteransprüche.The
Solution of the technical problem results from the features
of
Hierbei umfasst eine Batterieeinheit mindestens eine Batterie, wobei die Batterieeinheit mindestens einen Batteriekanal aufweist, wobei der Batteriekanal mindestens einen Kanal für ein Abgasrohr umfasst oder ausbildet, wobei in dem Kanal für ein Abgasrohr mindestens ein Abgasrohr anordenbar ist. Hierdurch wird vorteilhaft ermöglicht, eine Integration, insbesondere ein Nachrüsten, der Batterieeinheit in ein Hybrid-Fahrzeug zu ermöglichen, auch wenn bereits eine Abgasanlage mit einem Abgasrohr in dem dafür vorgesehenen Bauraum angeordnet ist. Der Batteriekanal verläuft dabei beispielsweise von einer Vorderseite der Batterieeinheit zu einer Rückseite der Batterieeinheit in Richtung eines Verlaufs des Abgasrohrs. Hierdurch muss der Verlauf des Abgasrohrs im Hybrid-Fahrzeug nicht verändert werden. Der Batteriekanal kann dabei tunnelförmig ausgeführt sein, wobei der Batteriekanal komplett von der Batterieeinheit umschlossen wird.in this connection a battery unit comprises at least one battery, wherein the Battery unit has at least one battery channel, wherein the Battery channel at least one channel for an exhaust pipe includes or forms, wherein in the channel for an exhaust pipe at least one exhaust pipe can be arranged. This will be advantageous allows for integration, especially retrofitting, to allow the battery unit in a hybrid vehicle even if already an exhaust system with an exhaust pipe in the for provided space is arranged. The battery channel runs in this case, for example, from a front side of the battery unit a back of the battery unit in the direction of a course of Exhaust pipe. As a result, the course of the exhaust pipe in the hybrid vehicle not be changed. The battery channel can be tunnel-shaped be executed, wherein the battery channel completely from the Battery unit is enclosed.
In einer bevorzugten Ausführungsform weist der mindestens eine Batteriekanal einen geradlinigen Verlauf auf. Weist der mindestens eine Batteriekanal einen geradlinigen Verlauf auf, so weist auch der Kanal für ein Abgasrohr einen geradlinigen Verlauf auf. Hiermit wird vorteilhaft ermöglicht, dass das Abgasrohr nicht um die Batterieeinheit herumgeführt werden muss. Ein geradliniger Verlauf des Batteriekanals ermöglicht einen geradlinigen Verlauf des Abgasrohres, wodurch die Abgasabführung verbessert wird. Insbesondere entstehen bei einem geradlinigen Verlauf des Abgasrohrs keine Druckverluste, die bei einem beispielsweise abknickenden Verlauf entstehen würden. Auch wird eine durch einen nicht geradlinigen Verlauf verursachte Leistungsminderung der Antriebsleistung bzw. ein Mehrverbrauch an Kraftstoff verhindert.In a preferred embodiment, the at least one battery channel has a straight course. If the at least one battery channel has a straight course, the channel for an exhaust pipe also has a straight course. This advantageously makes it possible that the exhaust pipe does not have to be guided around the battery unit. A straight course of the Batterieka Nals allows a straight-line course of the exhaust pipe, whereby the exhaust gas removal is improved. In particular, in the case of a rectilinear course of the exhaust pipe, there are no pressure losses that would occur if the course were bent, for example. Also, caused by a non-rectilinear curve performance reduction of the drive power or an excess fuel consumption is prevented.
In einer bevorzugten Ausführungsform ist der Batteriekanal zu einer Unterseite der Batterieeinheit hin angeordnet, wobei der Batteriekanal zur Unterseite hin offen ist. Hiermit wird vorteilhaft ermöglicht, die Batterieeinheit über dem Abgasrohr anzuordnen, was ein vereinfachtes Einsetzen der Batterieeinheit in das Hybrid-Fahrzeug ermöglicht. Unter einer Unterseite der Batterieeinheit versteht man eine Seite der Batterieeinheit, die in Richtung einer Fahrzeugunterseite hin orientiert ist. Selbstverständlich ist es auch vorstellbar, dass der Batteriekanal an weiteren Seiten der Batterieeinheit, beispielsweise einer Oberseite, angeordnet ist, wobei der Batteriekanal zu dieser weiteren Seite hin offen ist.In A preferred embodiment is the battery channel arranged to an underside of the battery unit, wherein the Battery channel is open towards the bottom. This will be advantageous allows the battery unit above the exhaust pipe to arrange what a simplified insertion of the battery unit in the hybrid vehicle allows. Under a bottom the battery unit is one side of the battery unit, which is oriented towards a vehicle underside. Of course It is also conceivable that the battery channel on other sides the battery unit, such as a top disposed is, with the battery channel open to this wider side is.
In einer weiteren Ausführungsform ist ein Mittel zur Temperierung der Batterieeinheit durch den mindestens einen Batteriekanal leitbar und/oder umfasst der mindestens eine Batteriekanal mindestens einen Kühlkanal, durch den das Mittel zur Temperierung der Batterieeinheit leitbar ist. Hierdurch wird vorteilhaft ermöglicht, dass der für die Anordnung des Abgasrohrs geschaffene Batteriekanal gleichfalls einer Temperierung der Batterieeinheit dient. Hierzu kann der Batteriekanal in zwei Kanäle, den Kanal für ein Abgasrohr und einen Kühlkanal, aufgeteilt werden. Alternativ ist vorstellbar, dass das Mittel zur Temperierung durch den Kanal für ein Abgasrohr geleitet wird. Das Mittel zur Temperierung verhindert einerseits, dass die von dem Abgasrohr an die Umgebung des Abgasrohres abgegebene Wärme die Batterieeinheit aufheizt. Neben dieser Isolationswirkung kann das Mittel zur Temperierung der Batterieeinheit auch zur Kühlung der Batterieeinheit eingesetzt werden. Das Mittel zur Temperierung kann dabei zum Kühlen und zum Heizen der Batterieeinheit eingesetzt werden. Ein Heizen der Batterieeinheit ist beispielsweise dann erforderlich, wenn ein Hybrid-Fahrzeug gestartet wird und die Batterieeinheit eine notwendige Betriebstemperatur noch nicht erreicht hat. Ebenfalls ist vorstellbar, dass durch das Mittel zur Temperierung die Wärmeabgabe des Abgasrohres an die Batterieeinheit derart beeinflusst wird, dass hierdurch eine gewünschte Temperierung der Batterieeinheit erreicht wird. So ist z. B. vorstellbar, dass nach einem Start des Hybrid-Fahrzeugs z. B. wenig oder kein Kühlmittel durch den Kühlkanal bzw. den Batteriekanal geleitet wird, wodurch eine Wärmeübertragung vom Abgasrohr zur Batterieeinheit stattfinden kann. Hat die Batterieeinheit eine gewünschte Betriebstemperatur erreicht, so wird (mehr) Kühlmittel durch den Kühlkanal bzw. Batteriekanal geleitet, wodurch eine Wärmeisolation der Batterieeinheit gegenüber dem Abgasrohr bewirkt wird.In Another embodiment is a means for temperature control the battery unit by the at least one battery channel conductive and / or the at least one battery channel comprises at least one Cooling channel through which the means for temperature control of the battery unit is conductive. This advantageously allows that the created for the arrangement of the exhaust pipe battery channel also a temperature of the battery unit is used. For this purpose can the battery channel into two channels, the channel for one Exhaust pipe and a cooling channel to be divided. alternative It is conceivable that the means for tempering through the channel for an exhaust pipe is passed. The means for tempering prevents, on the one hand, that of the exhaust pipe to the environment the heat emitted by the exhaust pipe heats the battery unit. In addition to this insulating effect, the means for temperature control the battery unit also for cooling the battery unit be used. The means for temperature control can be used for cooling and used to heat the battery unit. A heating the battery unit is required, for example, when a Hybrid vehicle is started and the battery unit a necessary Operating temperature has not yet reached. It is also conceivable that by the means for tempering the heat emission the exhaust pipe is influenced to the battery unit so that thereby a desired temperature of the battery unit is reached. So z. B. conceivable that after a start of Hybrid vehicle z. B. little or no coolant through the cooling channel or the battery channel is passed, whereby a heat transfer from the exhaust pipe to the battery unit can take place. If the battery unit has a desired operating temperature achieved, (more) coolant through the cooling channel or battery channel passed, creating a thermal insulation the battery unit is effected with respect to the exhaust pipe.
In einer weiteren Ausführungsform ist der Kühlkanal zwischen dem Kanal für ein Abgasrohr und der Batterieeinheit angeordnet. Eine solche Anordnung ermöglicht in vorteilhafter Weise eine Wärmeisolation der Batterieeinheit gegenüber der von dem Abgasrohr abgegebenen Wärme.In Another embodiment is the cooling channel between the duct for an exhaust pipe and the battery unit arranged. Such an arrangement allows in an advantageous manner Make a heat insulation of the battery unit opposite the heat emitted by the exhaust pipe.
In einer weiteren Ausführungsform sind in und/oder um den Kanal für ein Abgasrohr und/oder dem Kühlkanal Mittel zur Wärmeisolation angeordnet. Hierdurch ergibt sich eine verbesserte Wärmeisolation der Batterieeinheit gegenüber der von dem Abgasrohr abgegebenen Wärme. Mittel zur Wärmeisolation können dabei direkt in dem Kanal für ein Abgasrohr und/oder in dem Kühlkanal angeordnet sein. Es ist aber auch möglich, die Mittel zur Wärmeisolierung um den Kanal für ein Abgasrohr und/oder den Kühlkanal herum anzuordnen. Beispielsweise können die Mittel zur Wärmeisolation Teil der Batterieeinheit sein.In Another embodiment is in and / or around the Channel for an exhaust pipe and / or the cooling channel Arranged means for heat insulation. This results an improved heat insulation of the battery unit relative to the heat emitted by the exhaust pipe. Means for heat insulation can directly in the channel for an exhaust pipe and / or in the cooling channel be arranged. But it is also possible to use the funds for Thermal insulation around the duct for an exhaust pipe and / or to arrange the cooling channel around. For example The means of heat insulation can be part of the Be battery unit.
In einer weiteren Ausführungsform umfasst die Batterieeinheit weitere Kanäle, wobei in den weiteren Kanälen Mittel zur Temperierung leitbar sind. Hierdurch wird in vorteilhafter Weise ermöglicht, dass nicht ausschließlich die unmittelbare Umgebung des Kühlkanals bzw. des Batteriekanals eine Kühlwirkung erfährt.In In another embodiment, the battery unit comprises other channels, where in the other channels Means for temperature control are conductive. This will be advantageous Way that allows not only the immediate vicinity of the cooling channel or the battery channel undergoes a cooling effect.
Gemäß der Erfindung umfasst ein Fahrzeug mindestens eine Batterieeinheit und eine Abgasanlage mit mindestens einem Abgasrohr zur Abführung von Abgasen, wobei die Batterieeinheit mindestens einen Batteriekanal umfasst, der mindestens einen Kanal für ein Abgasrohr umfasst oder ausbildet, wobei das Abgasrohr in dem Kanal für ein Abgasrohr angeordnet ist.
