DEVICE AND METHOD FOR CONTROLLING THE TEMPERATURE OF AN ELECTRIC ENERGY STORE OF A VEHICLE

摘要

The invention relates to a device (16) for controlling the temperature of an electric energy store (14), in particular a rechargeable battery, of a vehicle (10), comprising a first flow path (24) which opens into a housing of the electric energy store (14) and comprising an air conditioning system (18) for air-conditioning a passenger compartment (12) of the vehicle (10), said air conditioning system having a heating and/or cooling device (30) and a second flow path (32) which leads from the at least one heating and/or cooling device (30) into the passenger compartment (12). The two flow paths (24, 32) are connected in the device (16) such that an airflow in one of the two flow paths (24, 32) is fluidically independent of an airflow in the respective other of the two flow paths (32, 24). The device (16) has a heat exchanger (44) which is connected in the two flow paths (24, 32) for a pure heat exchange between the air flows in the two flow paths (24, 32). The invention further relates to a corresponding vehicle (10) and to a corresponding method for controlling the temperature of an electric energy store (14) of a vehicle (10).
