1. A system for a motor vehicle for heating and/or cooling a battery and a vehicle interior, the system comprising:

  • a coolant circuit, which is thermally coupled to the battery;

    a refrigeration circuit having a condenser, a compressor, a first evaporator for cooling the vehicle interior, and a second evaporator for cooling the battery, the second evaporator having an evaporator-heat exchanger that is thermally coupled to the coolant circuit;

    an ambient air heat exchanger thermally coupled to the coolant circuit for transferring waste heat of the battery to the ambient air;

    at least one device for transferring heat from the evaporator-heat exchanger to the ambient air and/or the vehicle interior in order to transfer the waste heat of the battery to the ambient air and/or to the vehicle interior when the refrigeration circuit is turned off, and/or at least one device for transferring heat from the ambient air heat exchanger to the ambient air and/or to the vehicle interior in order to transfer the waste heat of the battery to the ambient air and/or the vehicle interior when the refrigeration circuit is turned off.
