Abstract: 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.

Abstract: A fuel gas tank arrangement in a vehicle. The fuel gas tank arrangement comprises a fuel gas tank for holding a pressurized fuel gas volume, and a valve configured to ventilate fuel gas from the fuel gas tank into ambient surroundings. The valve comprises a controllable valve actuator communicatively connected to a control unit. The valve actuator is configured to open the valve to a determined opening degree for controlling a flow rate of ventilated fuel gas. The disclosure also relates to method for safety ventilation of fuel gas from a fuel gas tank arrangement.
