Definitions
- the present invention relates to a hydrogen safe charging system based on real-time communication information of CHSS for a fuel cell, and provides a protocol for quickly charging fuel by measuring the temperature and pressure of a hydrogen tank in real time.
- a hydrogen vehicle is a vehicle that uses hydrogen as a fuel for power, and converts the chemical energy of hydrogen into mechanical energy by burning hydrogen in an internal combustion engine to drive an electric motor or by reacting hydrogen with oxygen in a fuel cell.
- Hydrogen is used to supply transportation fuel, and hydrogen fuel is dangerous compared to fuel due to its high-pressure and fast charging characteristics, and it is fully charged due to heat generation due to compression and Joule-Thomson effect. This is not easy. Accordingly, each country has developed a fueling protocol, and among them, there are many studies on the hydrogen fueling protocol using a lookup table for the pressure increase rate and the target pressure based on the charging parameters. However, this does not control charging based on real-time measured values, and various mobility such as forklifts, drones, and ships are being developed in addition to automobiles. If the conditions are not met, it cannot be applied, so accurate charging and control are impossible.
- One embodiment of the present invention reflects the structural information and thermodynamic information of the hydrogen tank sent by the CHSS to the hydrogen charger through wireless communication during hydrogen charging so that hydrogen can be charged more safely and quickly, hydrogen in the hydrogen tank

- CHSS Compressed Hydrogen Storage System
- hydrogen can be charged more safely and quickly by reflecting the structural information and thermodynamic information of the hydrogen tank sent by the CHSS to the hydrogen charger through wireless communication during hydrogen charging. So, by measuring the pressure and temperature of hydrogen in the hydrogen tank in real time and receiving the pressure and temperature measured in real time from CHSS through wireless communication in the hydrogen charger, the optimum pressure increase rate is calculated, and the calculated optimum pressure increase rate is By allowing the charging to proceed, the charging time can be minimized within the range where the pressure, temperature, and charging flow rate of hydrogen in the hydrogen tank do not deviate from the set threshold values.

- the charger control unit 310 may collect initial state values from the hydrogen tank 110 in the CHSS 100 and the hydrogen supply unit 330 of the hydrogen charger 300 .

It may include the value of a thermodynamic variable of hydrogen.
- the structural variable values of the hydrogen tank 110 include the number of hydrogen tanks 110 (N tank ), the hydrogen tank 110 inlet inner diameter (d inlet ), and the hydrogen tank 110 volume (V tank ). can At this time, it is assumed that the structural variable values of the hydrogen tank 110 mounted on one CHSS 100 are all the same. That is, it is assumed that the number, inner diameter, and volume of all hydrogen tanks 110 included in the CHSS 100 are standardized to have the same standard. These values are received to the charger control unit 310 through the IR receiver 260, and since they are unique values of the CHSS 100, they need only be received once before charging starts.
- the structural variable value of the data hydrogen transfer device 200 may include a pressure loss coefficient (K line ) of the data hydrogen transfer device 200 measured by the hydrogen supply unit 330 . Since this value is also a unique value of the data hydrogen transfer device 200, that is, the data hydrogen transfer device 200 called a charging line or a hydrogen charging line, it needs to be received only once before starting charging. However, the pressure loss coefficient (K line) data, but eigenvalues of hydrogen mobile device 200, CHSS (100), the pressure loss coefficient (K line) whole because it can vary depending on the type of data hydrogen mobile device 200 It may also vary depending on the type of CHSS 100 .

- the initial pressure increase rate (prr) for calculating the new pressure increase rate (prr new ) may be a value obtained by dividing 20 MPa/min by the number of hydrogen tanks (110). Based on the initial values of these variables, a new pressure increase rate (prr new ) is calculated through hydrogen filling simulation and applied to hydrogen filling, so the initial pressure increase rate (prr) is virtually insignificant.

That is, the second step (S3200) is a hydrogen filling simulation step, based on the initial value given in the first step (S3100), the mass flow rate ( ), the temperature in the hydrogen tank 110 ( ), the pressure in the hydrogen tank 110 ( ), the filling factor (SOC), and comparing the result of the simple thermodynamic model to select a relatively large value, the maximum mass flow rate ( ), maximum hydrogen tank temperature ( ), maximum hydrogen tank pressure ( ) to determine the value. The calculation process of the simple thermodynamic model is repeated while increasing the time by ⁇ t, and when the filling factor (SOC) becomes 100 or more, the repeated calculation is stopped.
- SOC filling factor
- the charger control unit 310 may calculate a difference between the determined mass flow rate, temperature, and pressure, and each pre-stored safety threshold value. At this time, the charger control unit 310 may set the pressure increase rate when all the differences are positive (+) values and one of the differences is less than or equal to the respective preset values through repeated calculation as the optimum pressure increase rate. have.
- each preset value may be set based on a small value of an acceptable level, that is, a research result.
- the third step (S3300) is a simulation result determination step, the charger control unit 310, the maximum mass flow rate (S3200) calculated in the second step (S3200) ), maximum hydrogen tank temperature ( ), maximum hydrogen tank pressure ( ) and the safety threshold (0.06 kg/s, 85 °C, 87.5 MPa) to compare the difference, that is, , ⁇ T, ⁇ P.
- the charger control unit 310 intends is the maximum mass flow rate ( ), maximum hydrogen tank temperature ( ), maximum hydrogen tank pressure ( ) does not exceed the safety threshold, the initial pressure increase rate (prr) is raised as much as possible to shorten the time required to charge hydrogen. If any one of the three values exceeds the safety threshold, it is a violation of the law.
- , ⁇ T, ⁇ P are all positive values
- one of the , ⁇ T, ⁇ P values is a preset value, for example, an acceptable small value (based on research results)
- the applied pressure increase rate (prr) is set and considered as the optimal pressure increase rate (prr).
- the considered optimum pressure increase rate (prr) is not the actual optimum pressure increase rate
- search and application are conducted in earnest in the fourth step below.
- the charger control unit 310 may search for and apply a pressure increase rate in the hydrogen supply unit 330 based on the calculated difference.
- the fourth step may be composed of a search step (S3400) and an application step (S3500).
- the charger control unit 310 reduces the pressure increase rate (prr), , ⁇ T, ⁇ P are all positive values, but , ⁇ T, ⁇ P value is not less than the set value, that is, a small value of an acceptable level, while repeating the second step (S3200) and the third step (S3300) by increasing the pressure increase rate (prr) Search for the optimum pressure rise rate (prr).
- the charger control unit 310 sets the optimum pressure increase rate (prr) searched for in S3100 to S3400 as a new pressure increase rate (prr new ), and transmits it to the hydrogen supply unit 330 to the hydrogen charger ( 300) continues to charge the hydrogen tank 110 of the CHSS 100 at a new pressure increase rate (prr new).
- the charger control unit 310 searches for and applies a pressure increase rate in the hydrogen supply unit 330 based on the calculated difference, and then, when a preset time elapses, the temperature and pressure of the hydrogen tank 110 and the hydrogen supply unit 330 . Based on the temperature and pressure of This step is a process of requesting a new optimal pressure increase rate (prr new) in the step (S3600) requesting to calculate, update the new optimal pressure increase rate (prr new) applied in step S3500.
- thermodynamic model used in the hydrogen filling simulation does not reflect heat transfer in the data hydrogen transfer device 200 and the hydrogen tank 110 . Therefore, an error occurs in the result of calculating the temperature of hydrogen in the hydrogen tank 110 . However, since the hydrogen filling simulation is performed based on the pressure and temperature in the hydrogen tank 110 in the current state during hydrogen filling, if the duration of the simulation is sufficiently short, the error may be reduced. Therefore, it is possible to repeat the hydrogen charging simulation for the remaining charging time by repeating until just before the hydrogen charging is completed.
