Abstract

A method is disclosed for the thermal conditioning of an electrochemical accumulator of a vehicle, wherein data are received and/or ascertained, and the data comprise a planned or expected parking duration, ambient data of the vehicle, thermal properties of the electrochemical accumulator, the received and/or ascertained data are evaluated, and based on the evaluated data steps are taken for the thermal conditioning of the electrochemical accumulator by the control unit prior to a parking of the vehicle, during a parking of the vehicle, or after a parking of the vehicle, wherein the steps for the thermal conditioning of the electrochemical accumulator remove or add thermal energy directly or indirectly to or from the electrochemical accumulator by a battery cooling circuit and/or a main cooling circuit of the vehicle.
