Abstract
Methods for accurately and conveniently calculating the temperature of gaseous hydrogen during vehicle fueling are disclosed. The metered amount of hydrogen added to the on-board storage tank, the ambient conditions, The pressure measured at the dispenser, and a correlation to account for heat transfer are the inputs to the methods of the present invention. These inputs eliminate the need for obtaining temperature and pressure information from the vehicle which is out of the control of the dispenser and/or energy provider. In addition, the use of the equation of the present invention does not require the fill rate to be limited and the corresponding fill time to be extended.
