Abstract
A method of refueling a tank of a vehicle with a hydrogen gas from a hydrogen refueling station, including initiating flow of hydrogen gas in a hose being controlled by a controller controlling a valve, opening the valve and monitoring the temperature and pressure of the hydrogen gas in tank, based on the monitored temperature and the monitored pressure establishing an estimated state of charge during the refueling, terminating the refueling when the estimated state of charge reaches an upper state of charge being above the tank rated density, the upper state of charge being determined on the basis of a pre-estimated correction of state of charge, the pre-estimated correction of state of charge designating a decrease of the estimated state of charge in the vehicle tank after the closing of the valve disconnecting the hose between the vehicle tank and the hydrogen source.
