Abstract
A coolant circuit for an at least partially electrically operated motor vehicle includes a first coolant line with a first coolant pump, the first coolant line is connected to a battery storage device for cooling or heating the battery storage device. A second coolant line with a second coolant pump, the second coolant line is connected to further motor vehicle components. A heat exchanger is arranged in a heat exchanger section of the coolant circuit and is connected to a refrigerant circuit of the motor vehicle. An electrical heating element is arranged at a heating section of the coolant circuit and is designed to heat coolant circulating in the coolant circuit.
