1. A thermal management system for a vehicle, wherein the vehicle comprises an occupant compartment and a propulsion system configured to provide motive power to the vehicle, and wherein the thermal management system comprises:
a propulsion coolant circuit configured to cool at least a portion of the propulsion system;
a heating circuit configured to heat the occupant compartment;
a heat pump circuit comprising a first evaporator in the propulsion coolant circuit and a condenser in the heating circuit, wherein the propulsion coolant circuit comprises a connecting conduit connecting the propulsion coolant circuit to the heating circuit at a position upstream of the condenser, and a first return conduit configured to return coolant to the propulsion coolant circuit from the heating circuit at a position downstream of the condenser; and
a first valve configured to control flow of coolant through the connecting conduit, wherein the propulsion system is an electric propulsion system comprising a battery, and wherein the first evaporator is further configured to cool the battery, wherein the propulsion coolant circuit comprises a coolant branch and a second valve configured to regulate the flow of coolant through the coolant branch, and wherein the first evaporator is arranged in the coolant branch of the propulsion coolant circuit.
