A temperature control device for temperature control of an electrical energy store for a motor vehicle includes a feed line element which is flushable by a temperature control fluid for the temperature control of the energy store, and which constitutes a first line element via which the temperature control fluid flowing in the feed line element can be admitted to the energy store, and includes a return line element which is flushable by the temperature control fluid, and which constitutes a second line element via which temperature control fluid flowing in the energy store can be evacuated from the energy store. The line elements are arranged in a housing which is common to the line elements, in which a housing bypass line element which is fluidically connected or connectable to the line elements is arranged, by way of which the energy store can be bypassed by the temperature control fluid.

Temperature control device for the temperature control of an electrical energy store for a motor vehicle, and motor vehicle

An air-conditioning system for an electrically driveable motor vehicle includes a coolant-conducting HVA circuit to which a traction battery and an evaporator for cooling the traction battery are connected, a coolant-conducting heating circuit for controlling the temperature of an interior compartment of the motor vehicle, to which heating circuit a condenser for releasing thermal power is connected, a coolant-conducting refrigeration circuit, to which the evaporator, the condenser and a compressor are connected, a heat exchanger, which is connected to the HVA circuit and which is controllably connectable to the heating circuit and which is configured for coolant-based transfer of thermal power from the heating circuit into the HVA circuit, and a control device.

A control system and method for a heating system of an electric vehicle or hybrid vehicle is embodied such that when there is a heating request for a high-voltage accumulator, an HVA heating mode is activated in which the high-voltage accumulator which is connected to an HVA circuit of the heating system is heated by an HVA heating source which is activated for this purpose so that heat is generated in the HVA circuit or transferred into the circuit. When there is a heating request for a passenger compartment of the vehicle, an air-conditioning heating mode is activated in which the passenger compartment is heated by a heating circuit, with heat which is generated in the heating circuit with an auxiliary heater or is transferred into the heating circuit with a heat pump, or both. When the air-conditioning heating mode is activated, it is determined whether or not there is a heating deficit which indicates whether the heating request can be completely satisfied with the auxiliary heater or with the heat pump or with both. If there is a heating deficit, an auxiliary heating mode is activated in which heat of the HVA heating source is transferred from the HVA circuit into the heating circuit by the heat pump in order to compensate the heating deficit.
