DEVICE AND METHOD FOR AIR-CONDITIONING AN ELECTRICAL ENERGY STORE FOR A MOTOR VEHICLE

摘要

The invention relates to a device (100) for air-conditioning an electrical energy store (50) for a motor vehicle, wherein the device (1) comprises: a heating element unit (10), which is designed to feed the electrical energy store (50) with thermal energy by means of conversion from another energy form; a heating circuit unit (20), which is designed to feed the electrical energy store (50) with the thermal energy by using waste heat generated by a secondary element (200); a sensor unit (30), which is designed to measure the temperature of the electrical energy store (50); and a control unit (40), which is designed to use the measured temperature of the electrical energy store (50) to determine a heating requirement for the electrical energy store (50) and to activate the heating element unit (10) and/or the heating circuit unit (20) in accordance with the heating requirement determined.
