Embodiment Construction

[0032] Preferred embodiments of the present invention are described below. Further details, preferred embodiments and refinements of the invention result from this.

[0033] In a two-point regulator for cooling electrochemical energy stores with lithium-ion batteries, the time-dependent actual temperature of the battery cells measured with a temperature sensor is used as a control variable and as an observation variable. The temperature is referred to here as T ist (t). This is a measurement of a representative cell of the entire energy store at a location in the vicinity of the cell terminals. The desired temperature at the measurement site is achieved by cooling in a cooling cycle using a vapor refrigerant and a refrigerant compressor at (here referred to as T oG is activated at the upper temperature limit of (herein referred to as T uG ) is deactivated at the lower temperature limit. Furthermore, the time-dependent voltage of the accumulator (here referred to as U(t)) ...

Abstract

Method for temperature regulation of an electrochemical energy store in a vehicle, wherein the electrochemical energy store has a cooling device for its cooling purpose, and wherein the actual value of the temperature of the electrochemical energy store is determined with a temperature measuring device and The desired value for the temperature of the electrochemical energy store is set by means of a two-point regulator which activates the cooling device at the upper temperature limit of the electrochemical energy store and at the lower temperature limit of the electrochemical energy store deactivating the cooling device, wherein the upper temperature limit of the two-point control device and / or the lower temperature limit of the two-point control device are determined in a time-dependent manner during operation of the electrochemical energy storage device or during activation of the cooling device, Furthermore, the upper temperature limit of the two-point regulator and / or the lower temperature limit of the two-point regulator are determined as a function of energy storage data and / or vehicle operating data.

Description

technical field [0001] The invention relates to a method for temperature regulation of an electrochemical energy store in a vehicle, wherein the electrochemical energy store has a cooling device for its cooling purpose and wherein the electrochemical energy store is determined using a temperature measuring device The actual value of the temperature of the accumulator and the desired value of the temperature of the electrochemical accumulator are set by means of a two-point regulator, which activates the cooling device in the case of an upper temperature limit of the electrochemical accumulator and The cooling device is deactivated in case of lower temperature limit of the energy converter. Background technique [0002] Electrochemical energy stores are becoming more and more interesting in the process of the continuous electrification of drives for vehicles for passenger and freight transport. In particular, secondary energy stores in the high-voltage range based on lithium...
