A thermal management system is provided for an electric vehicle. The thermal management system includes a refrigerant system, a coolant system, a plurality of thermal loads, and a coolant-refrigerant heat exchanger, that includes a secondary heater positioned to heat both the refrigerant and the coolant in the coolant-refrigerant heat exchanger. The secondary heater is sized to evaporate all of the refrigerant passing through the refrigerant flow path. A control system is operatively connected to the coolant-refrigerant heat exchanger, and is programmed to: operate the coolant-refrigerant heat exchanger in a secondary-heat-only mode in which the secondary heater evaporates the refrigerant in the refrigerant flow path without any heat input from the coolant in the coolant flow path, and to operate the coolant-refrigerant heat exchanger in a heat-scavenging mode in which at least some heat from the coolant in the coolant flow path evaporates the refrigerant in the refrigerant flow path.
