Apparatus for controlling the temperature of an electrical energy storage device

The invention relates to a device for controlling the temperature of an electrical energy accumulator (2), comprising a first temperature control circuit (1.1) and a second temperature control circuit (1.2) each having a temperature control medium and at least one tempering element (3). Here, a flow-influencing the temperature control element is provided which can be activated in dependence on at least one operating variable, at least of the first temperature control circuit (1.1), so that the temperature control medium is moved at least in the temperature-regulating element (3). The invention further relates to a method for operating a device for controlling the temperature of an electrical energy accumulator (2) and an electrical energy store (2) in combination with a device for controlling the temperature of the electrical energy accumulator (2).
