Thermal energy management system with high cooling capacity in idle and high performance passive battery cooling

An air conditioning and a battery cooling assembly comprising:

• an A/C coolant circuit and a coolant circuit, as well as a refrigerant circuit, wherein:
• the A/C coolant circuit and the coolant circuit are coupled together across a 4/2-way coolant valve in such a way that the A/C coolant circuit and the coolant circuit can be operated separately or can receive a flow in a serial manner;
• and
• the A/C coolant circuit further comprises at least one A/C coolant radiator for heat transfer to ambient air, a coolant pump and a condenser, by which the A/C coolant circuit is thermally connected to the refrigerant circuit;
• and
• the coolant circuit further comprises at least one battery cooler, a first coolant pump, a drivetrain coolant radiator for heat transfer to the ambient air and a chiller, by which the coolant circuit is thermally connected to the refrigerant circuit;
• and
• the refrigerant circuit further comprises at least one compressor, the condenser, an ambient heat exchanger for heat transfer to the ambient air or for heat uptake from the ambient air, a first expansion element and the chiller,
• wherein the 4/2-way coolant valve connects an outlet of the A/C coolant radiator to an inlet of the drivetrain coolant radiator and a first 3/2-way valve is situated at an outlet of the drivetrain coolant radiator with a connection to the A/C coolant circuit.
