摘要： A cooling system for a vehicle propelled by an electric machine. The cooling system is arranged, when the vehicle is operated in a braking mode, to control a first and a second radiator valve to direct a flow of fluid from a radiator through a first fluid circuit and prevent the flow of fluid from the radiator to enter the second fluid circuit, control a compressor arrangement to flow a refrigerant in a direction from a heat exchanger to a condenser of a third fluid conduit, and control a second circuit valve arrangement to direct a heat source fluid to circulate through a heat exchanger and an electric heat source.
