Definitions

  • the invention relates to a method for filling a vehicle tank with gas according to the preamble of the independent claim.
  • Gas-powered automobiles as an alternative to conventional motor vehicles powered by liquid fuels such as gasoline or diesel fuel are becoming increasingly important.
  • compressed natural gas is typically used as fuel for gas powered vehicles.
  • gaseous hydrogen is another fuel.
  • the vehicle tanks are usually filled to high pressures.
  • the vehicle tank is filled to a final pressure of about 200 bar based on a reference temperature of 15 ° C.
  • gaseous hydrogen even higher ultimate pressures, for example, 600 bar, sought, which is primarily due to the lower energy density of hydrogen (compared to natural gas).
  • the outside temperature is taken into account during filling. If one assumes that the final pressure at a reference temperature of 15 ° C for natural gas should be about 200 bar, then at an outside temperature of less than 15 ° C the refueling be terminated at a pressure of less than 200 bar, to ensure that with an increase in the outside temperature in the vehicle tank no unacceptably high pressure. Conversely, at an outside temperature of more than 15 ° C can be refueled up to a final pressure of more than 200 bar.
  • the vehicle tanks are thus designed so that even with fluctuations in the outside temperature no unacceptably high pressure in the tank arises, provided that the maximum final pressure at the refueling end Batend a pressure of 200 bar at the reference temperature of 15 ° C.
  • the vehicle tank is connected with a pressure-resistant line to a dispenser and filled the pressurized gas by means of the dispenser from a storage unit in the vehicle tank.
  • the final pressure allowed for the currently prevailing temperature is calculated.
  • a small amount of gas is introduced into the vehicle tank to effect pressure equalization between the vehicle tank and the dispenser.
  • the pressure prevailing in the vehicle tank initial pressure is measured after the pressure equalization in the dispenser and then filled a certain mass of gas in the vehicle tank.
  • the mass flow of the gas is interrupted and in turn measured the pressure prevailing in the vehicle tank pressure in the dispenser. From these pressure values, a relationship between the mass of the discharged gas and the pressure in the vehicle tank is determined. Based on this relationship, a mass of gas is calculated such that at least one more mass of gas must be supplied to fill the vehicle tank to the final pressure. After the calculated mass of gas has been supplied to the vehicle tank, the mass flow is interrupted again and determines the pressure prevailing in the vehicle tank pressure in the dispenser. The operations of calculating an additional mass of gas, supplying this mass of gas, and interrupting the mass flow for pressure determination become repeated several times until the temperature-corrected final pressure is reached in the vehicle tank.
  • the problem solving method for filling a vehicle tank with a gas is characterized by the features of the independent claim.
  • the filling process can be carried out without interruption.
  • the interruptions of the mass flow as in the EP-A-0-653 585 are proposed in each case to determine the current pressure prevailing in the vehicle tank pressure in the dispensing device are no longer necessary in the inventive method, because the measurement data required for the parameter online during the current filling in the vehicle tank are determined.
  • the inventive method is particularly fast and accurate, without concessions to the security are necessary.
  • the safety increases even more, because the level is determined based on measured data obtained in the vehicle tank.
  • the collection of data in the vehicle tank allows an even more accurate determination of the filling level, so that the permitted limits for the filling can be optimally exploited because they can be fully exploited without the danger of exceeding the safety limits.
  • the end value of the parameter, at which the filling is terminated, independent of the temperature, that is, a characteristic is selected, which represents the level of the vehicle tank, regardless of the temperature.
  • the characteristic of the density of the gas in the vehicle tank is determined.
  • a final value can be specified, namely the maximum permissible density or operating density, which is independent of the prevailing outside temperature during the filling.
  • the temperature-independent end value for the parameter has the advantage that it is no longer necessary to calculate a temperature-corrected value for the final pressure of the refueling.
  • a further advantageous measure is that the parameter is first determined before the vehicle tank is filled with gas, so that the current level of the vehicle tank is known as the initial value before the start of the filling. This initial value is used during refueling to compare the current fill level determined in the vehicle tank with the data determined in the dispenser. If there are discrepancies in this comparison, this indicates an error and appropriate countermeasures can be taken. As is generally customary, the mass of the released gas is detected by measurement in the dispensing device.
  • a control variable corresponding to the parameter is then determined from the emitted gas mass, the control variable is compared with the characteristic variable, and an error message or the cancellation of the filling takes place if the deviation between the parameter and the control variable exceeds a predefinable limit.
  • the reliability of gas refueling can be significantly increased, because there are two different determinations of the current level of the vehicle tank.
  • the characteristic variable representative of the current filling level is determined with the aid of the sensor device arranged in the vehicle tank, and on the other hand, the control variable corresponding to the characteristic variable is determined in the dispensing device on the basis of the mass of the discharged gas measured there. Due to the respective comparison of these two variables, errors in the filling, for example leaks, can be detected early and reliably.
  • the sensor device arranged in the vehicle tank comprises a temperature sensor and a pressure sensor with which the temperature and the pressure of the gas in the tank are measured. From this, the density of the gas is then determined as the parameter.
