Aus der
Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte elektrische Batterie und ein verbessertes Verfahren zum Betrieb einer elektrischen Batterie anzugeben.The invention is based on the object of specifying an improved over the prior art electric battery and an improved method for operating an electric battery.
Hinsichtlich der elektrischen Batterie wird die Aufgabe erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale und hinsichtlich des Verfahrens durch die im Anspruch 3 angegebenen Merkmale gelöst.With regard to the electric battery, the object is achieved by the features specified in claim 1 and in terms of the method by the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die elektrische Batterie umfasst ein Batteriegehäuse, einen innerhalb des Batteriegehäuses angeordneten elektrisch aktiven Teil und eine innerhalb des Batteriegehäuses angeordnete und thermisch mit dem elektrisch aktiven Teil gekoppelte Temperiereinheit zur Temperierung des elektrisch aktiven Teils.The electric battery comprises a battery housing, an electrically active part arranged within the battery housing and a temperature control unit arranged inside the battery housing and thermally coupled to the electrically active part for temperature control of the electrically active part.
Erfindungsgemäß ist innerhalb des Batteriegehäuses ein Gleichspannungswandler angeordnet, welcher thermisch mit der Temperiereinheit gekoppelt ist.According to the invention, a DC-DC converter is arranged within the battery housing, which is thermally coupled to the temperature control unit.
Mittels des Gleichspannungswandlers ist es in besonders vorteilhafter Weise möglich, bei Bedarf den elektrischen aktiven Teil der Batterie mittels einer vom Gleichspannungswandler in Form von Wärme erzeugten Verlustleistung über die Temperiereinheit zu beheizen. Hierzu sind in besonders vorteilhafter Weise keine zusätzlichen Bauteile, wie beispielsweise Heizmatten oder Peltier-Elemente, und zugehörige elektrische Kontaktierungen erforderlich, woraus ein geringerer Bauraum- und Materialbedarf sowie Montage- und Kostenaufwand resultieren. Gleichzeitig ist jedoch eine gezielte Ansteuerbarkeit der Gleichspannungswandlers und somit eine steuerbare Erwärmung des elektrisch aktiven Teils realisierbar.By means of the DC-DC converter, it is possible in a particularly advantageous manner, if necessary, to heat the electrically active part of the battery by means of a power loss generated by the DC-DC converter in the form of heat via the temperature control unit. For this purpose, no additional components, such as heating mats or Peltier elements, and associated electrical contacts are required in a particularly advantageous manner, resulting in a smaller space and material requirements and installation and costs result. At the same time, however, a targeted controllability of the DC-DC converter and thus a controllable heating of the electrically active part can be realized.
