TEMPERATURE CONTROL METHOD FOR AN ELECTROCHEMICAL ENERGY STORE IN A VEHICLE

摘要

The invention relates to a temperature control method for an electrochemical energy store in a vehicle, wherein the electrochemical energy store has a cooling device for the purpose of cooling thereof, and wherein an actual temperature value of the electrochemical energy store is determined by a temperature measuring means and a target temperature value of the electrochemical energy store is set by a two-point control device which activates the cooling device at an upper temperature limit of the electrochemical energy store and deactivates the cooling device at a lower temperature limit of the electrochemical energy store, wherein the upper temperature limit of the two-point control device and/or the lower temperature limit of the two-point control device is determined during the operation of the electrochemical energy store, or during the activation of the cooling device, in a time-dependent manner, and wherein the upper temperature limit of the two-point control device and/or the lower temperature limit of the two-point control device is established depending on energy store data and/or vehicle operating data.
