The body includes at least a first wall 3,7; 4,8 and a second wall 5,9; 6,9 arranged transversely to the first wall. The first wall and the second wall run parallel to an axis. The cavity is at least partially defined by the first wall and the second wall. The first wall includes first 3,4 and second 7,8 heat conducting layers to form a first heat dissipating path in a first direction extending transverse to the axis. The second wall includes first 5,6 and second 9 heat insulating layers to form a heat conduction barrier for preventing heat dissipation in a second direction extending transverse to both the first direction and the axis. This arrangement enables heat transfer to be efficiently directed through the heat conducting walls. Another aspect of the invention discusses providing a plurality of cells, preferably pouch cells, in face-to-face contact with each other to form a stack, which is in contact ...

METHOD FOR CONDITIONING A BATTERY OF A VEHICLE

Die Erfindung betrifft ein Verfahren zum Temperieren einer Batterie eines Fahrzeuges mittels einer Temperiereinrichtung zum Kühlen und/oder Aufwärmen der Batterie, um die Temperatur der Batterie in den Bereich einer definierten Zieltemperatur (Tz) zu bringen oder bei der definierten Zieltemperatur (Tz) zu halten. Um die Batterie auf möglichst einfache Weise zu temperieren ist vorgesehen, dass die Temperierung der Batterie auf der Basis zumindest einer prädiktiven Information der Batterie oder des Fahrzeuges erfolgt.
