Abstract
Description
Die Erfindung betrifft eine Kreislaufanordnung zur Kühlung von Antriebskomponenten eines Elektro- oder Hybridfahrzeugs gemäß dem Oberbegriff des Anspruchs 1. Weiterhin betrifft die Erfindung ein Verfahren zum Betrieb der Kreislaufanordnung gemäß dem Oberbegriff des Anspruchs 8.The invention relates to a circuit arrangement for cooling drive components of an electric or hybrid vehicle according to the preamble of
Herkömmlicherweise weisen Hybrid- und/oder Elektrofahrzeuge jeweils separate Kühlkreisläufe zur Kühlung einer Hochvoltbatterie, von elektrischen Antriebskomponenten und/oder einer Verbrennungskraftmaschine auf.Conventionally, hybrid and / or electric vehicles each have separate cooling circuits for cooling a high-voltage battery, of electric drive components and / or an internal combustion engine.
So zeigt zum Beispiel die Schrift
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem Stand der Technik verbesserte Kreislaufanordnung zur Kühlung von Antriebskomponenten eines Elektro- oder Hybridfahrzeugs und ein verbessertes Verfahren zum Betrieb der Kreislaufanordnung anzugeben.The invention has for its object to provide a comparison with the prior art improved circuit arrangement for cooling drive components of an electric or hybrid vehicle and an improved method for operating the circuit arrangement.
Hinsichtlich der Kreislaufanordnung zur Kühlung von Antriebskomponenten eines Elektro- oder Hybridfahrzeugs wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst.With regard to the circuit arrangement for cooling drive components of an electric or hybrid vehicle, the object is achieved by the features specified in
Hinsichtlich des Verfahrens zum Betrieb der Kreislaufanordnung wird die Aufgabe erfindungsgemäß durch die im Anspruch 8 angegebenen Merkmale gelöst.With regard to the method for operating the circuit arrangement, the object is achieved by the features specified in
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous developments of the invention are the subject of the dependent claims.
Bei der Kreislaufanordnung zur Kühlung von Antriebskomponenten eines Elektro- oder Hybridfahrzeugs sind erfindungsgemäß zumindest eine Kühlmittelpumpe, ein Innenraumwärmetauscher, eine Zuheizvorrichtung, elektrische Antriebskomponenten und ein Niedertemperaturkühler in einem unverzweigten Kühlkreislauf angeordnet. Der Niedertemperaturkühler ist mittels einer Bypassleitung überbrückbar in der Kreislaufanordnung integriert.In the circuit arrangement for cooling drive components of an electric or hybrid vehicle, at least one coolant pump, an indoor heat exchanger, a Zuheizvorrichtung, electric drive components and a low-temperature radiator are arranged in an unbranched cooling circuit according to the invention. The low-temperature cooler can be bridged by means of a bypass line integrated in the circuit arrangement.
Die Hochvoltbatterie, welche in einem separat betreibbaren Hochvoltbatteriekühlkreislauf angeordnet ist, ist in den Kühlkreislauf einkoppelbar.The high-voltage battery, which is arranged in a separately operable high-voltage battery cooling circuit, can be coupled into the cooling circuit.
Dadurch ist vorteilhafterweise ein gemeinsamer Kühlkreislauf aller Hochvolt-Komponenten im Fahrzeug geschaffen.As a result, a common cooling circuit of all high-voltage components in the vehicle is advantageously created.
Als unverzeigter Kühlkreislauf wird dabei ein Kühlkreislauf bezeichnet, bei welchem ein im Kühlkreislauf zirkulierender Kühlmittelstrom nicht aufgeteilt oder aufgespaltet wird, wobei aber einzelne Komponenten durch einen Bypass vom Kühlmittelstrom umgangen werden können.As an unseparated cooling circuit while a cooling circuit is referred to, in which a circulating in the cooling circuit coolant flow is not split or split, but individual components can be bypassed by a bypass of the coolant flow.
Mittels der Zuheizvorrichtung ist besonders vorteilhafterweise eine schnelle und bedarfsgerechte Aufheizung der Hochvoltbatterie und mittels des Innenraumwärmetauschers eines Fahrzeuginnenraums ermöglicht.By means of the Zuheizvorrichtung a rapid and needs-based heating of the high-voltage battery and by means of the interior heat exchanger of a vehicle interior is particularly advantageously possible.
Bei einer hohen Lastanforderung an einen Antriebsstrang kann die Hochvoltbatterie vom Kühlkreislauf getrennt werden und über den Hochvoltbatteriekühlkreislauf gekühlt werden, so dass eine effizientere Kühlung ermöglicht ist. Dadurch ist eine signifikante Verbesserung der Lade- und Entladeleistung der Hochvoltbatterie und eine daraus resultierende verbesserte Reichweite oder verlängerte Betriebsdauer eines Elektrofahrzeugs ermöglicht.With a high load requirement on a drive train, the high-voltage battery can be separated from the cooling circuit and cooled by the high-voltage battery cooling circuit, so that more efficient cooling is possible. This allows a significant improvement in the charging and discharging power of the high-voltage battery and a resulting improved range or extended life of an electric vehicle.
Weiterhin ist eine effiziente Nutzung der Abwärme der Hochvolt-Komponenten für die Aufheizung des Fahrzeuginnenraums ermöglicht, so dass keine zusätzliche Energie zur Aufheizung des Fahrzeuginnenraums zugeführt werden muss.Furthermore, an efficient use of the waste heat of the high-voltage components for the heating of the vehicle interior is made possible, so that no additional energy for heating the vehicle interior must be supplied.
Besonders vorteilhafterweise sind Kosten- und Bauraumvorteile durch ein derart integriertes Kühl- und Wärmemanagementsystem in einem Elektro- oder Hybridfahrzeug ermöglicht.Particularly advantageous cost and space advantages are made possible by such an integrated cooling and thermal management system in an electric or hybrid vehicle.
Beim Verfahren zum Betrieb einer Kreislaufanordnung zur Kühlung von Antriebskomponenten eines Elektro- oder Hybridfahrzeugs wird erfindungsgemäß zur Aufheizung eines Kühlkreislaufs ein Brennkraftmaschinenkühlkreislauf in den Kühlkreislauf eingekoppelt und die Zuheizvorrichtung aktiviert, wobei eine Bypassleitung des Niedertemperaturkühlers aktiviert ist und die Hochvoltbatterie in den Kühlkreislauf eingekoppelt ist.In the method for operating a circuit arrangement for cooling drive components of an electric or hybrid vehicle according to the invention for heating a cooling circuit coupled with an engine cooling circuit in the cooling circuit and activates the Zuheizvorrichtung, wherein a bypass line of the low-temperature radiator is activated and the high-voltage battery is coupled into the cooling circuit.
