TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The energy storage data and the vehicle operating data are stored on at least one control unit of the vehicle or a storage medium of the vehicle, which the energy storage data and the vehicle operating data with measuring means in the vehicle are determined or by calculation performed on the control unit, are determined or by simulation performed on the control device, are determined or received from a communication device of the vehicle, and the energy storage data and the vehicle operating data serves as input variables of the temperature control method. The energy store data comprises a recording of the temperature actual value of the electrochemical energy storage device in function of time, which a time-dependent temperature gradient is determined from the recording of the temperature actual value, 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 the time-dependent temperature gradients. The energy store data comprises a time-dependent recording of the charging- and discharging current of the electrochemical energy storage, and the time-dependent recording of the voltage comprises the electrochemical energy storage, which a time-dependent relative state of charge of the electrochemical energy storage is determined from the recording of the current and recording of the voltage, 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 the time-dependent relative state of charge. A time-dependent internal resistance of the electrochemical energy storage is determined from the recording of the current and the recording of the voltage, 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 the time-dependent internal resistance. The vehicle operating data comprises a time-dependent recording of ambient temperature of the vehicle, 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 the ambient temperature. The vehicle operating data comprises the distance profile of an upcoming travel route determined by a navigation device of the vehicle, information for traffic conditions along the upcoming travel route received from a communication device of the vehicle; information of a weather forecast at the location of the vehicle and along the upcoming travel route received from the communication device of the vehicle, 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 the characteristics of the route profile, traffic conditions and/or the weather forecast. The vehicle operation data comprises information about a user behavior, which characterizes a particular driver of the vehicle, where the driver i is identified in a vehicle identification device, the user behavior of particular driver is determined from the recording of the charging- and discharging current of electrochemical energy storage for a long period of observation or benefited/received is determined from a recording of acceleration and deceleration of the vehicle for a long period of observation, 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 characteristics of user behavior of particular driver.
