NOVELTY - Temperature control method for electrochemical energy storage in a vehicle, where the electrochemical energy storage comprises a cooling device for the purpose of cooling, and a temperature value of electrochemical energy storage is determined by a temperature measuring means and a temperature set value of the electrochemical energy storage is adjusted by a two-point control device, which activates the cooling device with upper temperature limit of the electrochemical energy storage and deactivates the cooling means at lower temperature limit of the electrochemical energy storage device.    USE - Used as the temperature control method for electrochemical energy storage in the vehicle.    ADVANTAGE - The method: slows down the aging of the battery cells; exhibits improved charging- and discharging efficiency; reduces the operating time of cooling, thus lowering the wear of the carbon cycle components; and increases energy efficiency of the vehicle.    DETAILED DESCRIPTION - Temperature control method for electrochemical energy storage in a vehicle, where the electrochemical energy storage comprises a cooling device for the purpose of cooling, and a temperature value of the electrochemical energy storage is determined by a temperature measuring means and a temperature set value of the electrochemical energy storage is adjusted by a two-point control device, which activates the cooling device with an upper temperature limit of the electrochemical energy storage and deactivates the cooling means at a lower temperature limit of the electrochemical energy storage device. The upper temperature limit of the two-point control device and/or the lower temperature limit of the two-point control device are determined during operation of the electrochemical energy storage or during activation of the cooling device in a time-dependent manner, and the upper temperature limit of the two-point control device and/or the lower temperature limit of the two-point control device are determined depending on energy storage data and/or vehicle operating data.
