Method for controlling the temperature of a battery arrangement and temperature-controlled battery arrangement

Abstract

The invention relates to a method for controlling the temperature of a battery arrangement made up of at least one battery cell by means of a cyclically operated adsorption heat pump, consisting of an adsorber and a phase converter with a working medium circulated between the adsorber and the phase converter, wherein the at least one battery cell is brought into thermal contact with an adsorbent of the adsorber and the temperature of the battery cell is controlled in that the battery arrangement picks up adsorption heat and gives off desorption heat, wherein the heat released in the phase converter during a condensation process of the working medium and the heat picked up during an evaporation process of the working medium is dissipated to the environment and supplied from the latter. The method is characterized in that the battery arrangement and the adsorber are, if necessary, brought into thermal contact, via an auxiliary fluid circuit, with a heat transfer fluid circulated in the auxiliary fluid circuit, wherein the heat transfer fluid is brought into thermal contact with external heat sources and/or heat sinks, wherein the battery arrangement is supplied, if necessary, with thermal energy from external heat sources via the auxiliary fluid circuit or thermal energy is withdrawn from the battery arrangement via the auxiliary fluid circuit and dissipated to external heat sources.
