Method for controlling pressure release in a liquid gas fuel volume, a liquid gas fuel volume, and a vehicle comprising the liquid gas fuel volume

Abstract

A computer-implemented method for controlling pressure release in a liquid gas fuel volume in a vehicle, the liquid gas fuel volume being arranged with a control unit and a pressure release valve configured to automatically ventilate gas to an external environment when a pressure in the liquid gas fuel volume exceeds a predetermined ventilation set point. The method comprises obtaining by the control unit data, determining by the control unit a refueling pressure set point for the liquid gas fuel volume based on the obtained data, and at a subsequent refueling operation, communicating the refueling pressure set point as a maximum pressure threshold to be used when refueling the liquid gas fuel volume. A control unit to control pressure release according to the method, a computer program, a computer-readable medium, a liquid fuel gas volume arranged with the control unit, and a vehicle comprising the liquid fuel gas volume.
