Description
Die Erfindung betrifft eine Vorrichtung zur Temperierung einer elektrischen Batterie eines Fahrzeugs gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft weiterhin ein Fahrzeug.The invention relates to a device for controlling the temperature of an electric battery of a vehicle according to the preamble of
In Fahrzeugen mit Verbrennungsmotoren und Hybridfahrzeugen werden elektrische Batterien z. B. als Starterbatterien für einen Anlasser des Verbrennungsmotors und/oder als Traktionsbatterien für einen Elektromotor eingesetzt. Bei schweren Nutzfahrzeugen, wie z. B. Lastkraftwagen, sind die elektrischen Batterien beispielweise als wiederaufladbare Blei-Säure-Akkumulatoren oder Lithium-Ionen Akkumulatoren ausgebildet.In vehicles with internal combustion engines and hybrid vehicles electric batteries z. B. used as starter batteries for a starter of the internal combustion engine and / or as traction batteries for an electric motor. For heavy commercial vehicles, such. As trucks, the electric batteries are for example designed as rechargeable lead-acid batteries or lithium-ion batteries.
Eine Ladestromaufnahmefähigkeit solcher elektrischer Batterien ist abhängig von einer Elektrolytemperatur und damit abhängig von einer Umgebungstemperatur. Bei sinkender Elektrolytemperatur, z. B. bei niedrigen Umgebungstemperaturen im Winter, nimmt die Ladestromaufnahmefähigkeit signifikant ab. Insbesondere wenn die Umgebungstemperaturen unter den Gefrierpunkt sinken, wird eine Ladestromaufnahmefähigkeit der elektrischen Batterie im Betrieb des Fahrzeugs deutlich reduziert. Eine Temperierung der elektrischen Batterie des Fahrzeugs ist somit für eine langfristige, zuverlässige Startfähigkeit des Fahrzeugs erforderlich.A charging current capacity of such electric batteries is dependent on an electrolyte temperature and thus dependent on an ambient temperature. With decreasing electrolyte temperature, for. B. at low ambient temperatures in winter, the charging current capacity decreases significantly. In particular, when the ambient temperatures fall below the freezing point, a charging current capacity of the electric battery in the operation of the vehicle is significantly reduced. A temperature control of the vehicle's electric battery is thus required for a long-term, reliable starting capability of the vehicle.
Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte Vorrichtung zur Temperierung einer elektrischen Batterie sowie ein gegenüber dem Stand der Technik verbessertes Fahrzeug anzugeben.The invention is based on the object to provide a comparison with the prior art improved device for controlling the temperature of an electric battery and an improved over the prior art vehicle.
Hinsichtlich der Vorrichtung wird die Aufgabe erfindungsgemäß mit den in Anspruch 1 angegebenen Merkmalen gelöst. Hinsichtlich des Fahrzeugs wird die Aufgabe erfindungsgemäß mit den in Anspruch 9 angegebenen Merkmalen gelöst.With regard to the device, the object is achieved according to the invention with the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Eine Vorrichtung zur Temperierung einer elektrischen Batterie eines Fahrzeugs umfasst ein mit der elektrischen Batterie thermisch gekoppeltes Temperierelement. Erfindungsgemäß ist das Temperierelement in einen Temperierkreislauf einer Verbrennungskraftmaschine des Fahrzeugs integriert und zur Temperierung einer außerhalb eines Fahrzeuginnenraums angeordneten elektrischen Batterie ausgebildet.A device for controlling the temperature of an electric battery of a vehicle comprises a tempering element which is thermally coupled to the electric battery. According to the invention, the tempering element is integrated in a temperature control circuit of an internal combustion engine of the vehicle and designed for controlling the temperature of an electric battery arranged outside a vehicle interior.
Mittels der Vorrichtung kann eine im Betrieb des Fahrzeugs erzeugte Verlustwärme der Verbrennungskraftmaschine zur Temperierung der außerhalb des Fahrzeuginnenraums angeordneten elektrischen Batterie des Fahrzeugs genutzt werden. Der Fahrzeuginnenraum ist hier als ein verschließbarer, von einer Fahrzeugkarossierie begrenzter Innenraum zu verstehen, welcher beispielsweise eine Fahrgastzelle, einen Motorraum und weitere verschließbare Innenräume des Fahrzeugs definiert. Die elektrische Batterie ist somit an dem Fahrzeug einer äußeren Umgebung zugewandt angeordnet und daraus resultierend den Umgebungstemperaturen direkt ausgesetzt.By means of the device, a heat loss of the internal combustion engine generated during operation of the vehicle for temperature control of the arranged outside the vehicle interior electric battery of the vehicle can be used. The interior of the vehicle is here to be understood as a closable interior space delimited by a vehicle body, which defines, for example, a passenger compartment, an engine compartment and further closable interior spaces of the vehicle. The electric battery is thus arranged facing the vehicle to an external environment and as a result directly exposed to the ambient temperatures.
Die Verlustwärme wird über den Temperierkreislauf von der Verbrennungskraftmaschine abgeführt und kann somit dem Temperierelement der Vorrichtung zur Verfügung gestellt werden. Damit ist die Vorrichtung ohne einen erhöhten Kraftstoff- und/oder Stromverbrauch im Betrieb des Fahrzeugs betreibbar.The heat loss is dissipated via the temperature control circuit of the internal combustion engine and can thus be made available to the tempering of the device. Thus, the device without an increased fuel and / or electricity consumption during operation of the vehicle is operable.
Die elektrische Batterie ist hierbei beispielsweise eine Starterbatterie des Fahrzeugs, welche – wie bereits eingangs beschrieben – der Verbrennungskraftmaschine elektrische Energie zum Starten des Fahrzeugs zur Verfügung stellt. Dadurch, dass die elektrische Batterie mittels der Verlustwärme der Verbrennungskraftmaschine temperiert, insbesondere erwärmt wird, kann auf kostengünstige Art und Weise eine Ladestromaufnahmefähigkeit der elektrischen Batterie auch bei tiefen Umgebungstemperaturen, z. B. Temperaturen unter 0°C, sichergestellt werden. Zudem wird daraus resultierend eine Startfähigkeit des Fahrzeugs langfristig sichergestellt sowie ein Risiko von Fahrzeugausfällen aufgrund einer Tiefenentladung der elektrischen Batterie verringert.The electric battery here is, for example, a starter battery of the vehicle, which - as already described above - provides the internal combustion engine with electrical energy for starting the vehicle. The fact that the electric battery tempered by means of the heat loss of the internal combustion engine, in particular is heated, can cost-effective manner a charging current capacity of the electric battery even at low ambient temperatures, eg. As temperatures below 0 ° C, be ensured. In addition, as a result, a starting ability of the vehicle is ensured in the long term and a risk of vehicle breakdown due to a deep discharge of the electric battery is reduced.
