Title: REGULATING DEVICE FOR REGULATING A COOLING CIRCUIT FOR TEMPERATURE CONTROL OF A BATTERY SYSTEM HAVING MORE THAN ONE HEATING AND/OR COOLING ELEMENT
Abstract:
A regulating device for regulating a cooling circuit for the temperature control of a battery system having more than one heating and/or cooling element is described, wherein the regulating device comprises two regulating stages arranged successively. The regulating device according to the invention is characterised in that the first regulating stage (1A) is designed such that a specific cooling/heating power (Pnom) of the cooling circuit (3) is determined depending on one or more input variables or a variable proportional thereto, a regulating deviation thereof can be determined and a desired temperature (tnom) of the cooling agent or a variable proportional thereto can be output as a manipulated variable of the first regulating stage (1A) from the regulating deviation, and the second regulating stage (1B) is designed such that the manipulated variable of the first regulating stage (1A) can be supplied to the second regulating stage (1B) as a guide variable, a regulating deviation therefrom can be determined and an abstract signal (Sarb) can be output as a manipulated variable of the second regulating stage (1B).
