Description

  The present invention relates to a fuel filling method for a fuel cell vehicle or a fuel filling system for a fuel cell vehicle.

  The fuel cell vehicle travels by supplying oxygen-containing air and hydrogen to the fuel cell and driving the electric motor using the electric power generated thereby. In recent years, a fuel cell vehicle using such a fuel cell as an energy source for generating power has been put into practical use. Hydrogen is required to generate electricity with a fuel cell. However, in recent fuel cell vehicles, a sufficient amount of hydrogen is stored in advance in a hydrogen tank equipped with a high-pressure tank or an occlusion alloy. Those that use hydrogen are the mainstream. Along with this, research is also being actively conducted on a so-called communication filling technique for quickly filling a tank with a necessary amount of hydrogen.

  Communication filling is a technique in which information relating to a hydrogen tank is transmitted as a data signal to a station using some communication means from the vehicle side, and the station performs filling control based on the received data signal. The hydrogen tank is provided with a sensor that detects the temperature and pressure of the hydrogen gas in the hydrogen tank. From the vehicle side, information on the temperature and pressure of the hydrogen tank is included based on the output of these sensors (hereinafter, information that fluctuates during hydrogen filling, such as the temperature and pressure of the hydrogen tank, is collectively referred to as status information). Send the data signal to the station side. The station side fills with hydrogen in an appropriate manner according to the state of the hydrogen tank based on the acquired state information.

  In recent years, information on the heat dissipation characteristics of the hydrogen tank such as the capacity, heat capacity, and materials of the hydrogen tank (hereinafter, information related to the heat dissipation characteristics of the hydrogen tank is collectively referred to as specific information) is transmitted in addition to the above state information. The technique to do is also proposed (refer patent document 1). If the data signal transmitted from the vehicle side includes not only the state information of the hydrogen tank but also unique information, the station side can grasp the heat dissipation characteristics of the hydrogen tank. For this reason, in filling control using state information and unique information, for example, the temperature of the hydrogen tank can be accurately predicted, and hydrogen can be filled in an optimal manner so that the temperature of the hydrogen tank does not exceed a predetermined temperature. Contributes to shortening of time.

  Hereinafter, techniques for performing filling control based on such state information and unique information are collectively referred to as unique communication filling. Further, a technique for performing filling control using state information but not using specific information is referred to as general communication filling in contrast to the specific communication filling.

  By the way, in the conventional unique communication filling, information recorded in a storage medium provided in the communication device on the vehicle side is used as the unique information of the hydrogen tank transmitted from the vehicle to the station. However, the hydrogen tank may be replaced with a different type from that originally installed, or the communication device may be replaced with a different model number. In such a case, the unique information of the hydrogen tank different from the hydrogen tank actually mounted may be transmitted from the vehicle side to the station side. In addition, if unique communication filling is performed based on incorrect unique information, it may take more time than necessary to fill up or it may not be able to fill up, so the user may suffer unintended disadvantages. There is.

  It is an object of the present invention to provide a fuel filling method and a fuel filling system that can prevent unique communication filling from being performed based on erroneous unique information.

  (1) The fuel filling method of the present invention is a method of filling fuel in a fuel tank (for example, a hydrogen tank 31 described later) mounted on a fuel cell vehicle (for example, a fuel cell vehicle V described later), A reading step (for example, S1 in FIG. 2 described later) for reading the specific information of the fuel tank recorded in the fuel tank, the specific information obtained by the reading step, and a storage medium (for example, a fuel tank) The unique information is used when it is confirmed by the collation step that the unique information of the fuel tank recorded in the ROM of the communication calculation ECU 6 (to be described later) matches the two unique information.

In the filling step, if it is confirmed that the two pieces of unique information match in the matching step, the fuel is filled in a manner determined based on both the state information and the unique information from the communication device. When communication filling is performed and it is not confirmed that the two pieces of unique information coincide with each other in the collating step, the fuel is filled in a manner determined based on only the state information of the two pieces of information from the communication device. It is preferable to perform general communication filling or non-communication filling in which fuel is filled in a predetermined manner.

  (3) In this case, the fuel tank includes an ID tag (for example, a storage medium 33 to be described later) that generates a signal according to the unique information, and the ID tag is more than the surface of the outermost layer of the fuel tank. It is preferable to be provided inside a portion other than the inside of the layer of the conductive material, and in the reading step, a signal generated from the ID tag is read electromagnetically.

  (4) In this case, the outermost layer of the fuel tank is formed of a transparent material, and a pattern according to the specific information (e.g., between the outermost layer and the innermost layer and the inner layer thereof) A storage medium 33) to be described later is provided, and the pattern is preferably optically read in the reading step.

  (5) A fuel filling system of the present invention (for example, a hydrogen filling system S described later) includes a fuel tank for storing fuel gas (for example, a hydrogen tank 31 described later) and a communication device for transmitting information related to the fuel tank to the outside. A fuel cell vehicle (for example, a fuel cell vehicle V to be described later) on which (for example, a communication calculation ECU 6 and an infrared communication device 5 to be described later) are mounted, and a fuel supply device (for example, a hydrogen to be described later) for supplying fuel to the fuel tank. Station 9), the fuel tank is recorded with unique information of the fuel tank, the communication device is recorded with unique information of the fuel tank, and the unique information recorded in the fuel tank The collation means (for example, communication calculation ECU 6 described later) for collating the information with the unique information recorded in the communication device, and the two unique information are obtained by the collation means. When it is confirmed that the match includes the the filling control means for filling the fuel based on the unique information (e.g., the station-side control device 94 to be described later), the.

  (1) In the present invention, the unique information recorded in the fuel tank is read (reading step), the unique information is collated with the unique information recorded in a storage medium different from the fuel tank (collation step), When it is confirmed that the two match, the fuel is filled using the unique information (filling step). As described above, according to the present invention, when the unique information recorded in the fuel tank itself and the unique information recorded in a different storage medium match, the filling is performed using the unique information. Therefore, it is possible to prevent filling of unique communication based on the unique information.

  (2) In the present invention, when the match between the two pieces of unique information is not confirmed as a result of the collation, the general communication filling using the state information or the non-communication filling for filling the fuel in a predetermined manner is performed. . As a result, even when the unique information does not match, fuel can be filled, so that merchantability can be improved.

  (3) In the present invention, an ID tag that generates a signal corresponding to the specific information is provided in a portion inside the surface of the outermost layer of the fuel tank and other than the inside of the layer of the conductive material.

Read optically. Thereby, it is possible to prevent the pattern from being easily tampered without interfering with reading of the unique information. In addition, this makes it possible to more effectively prevent filling of unique communication based on erroneous unique information.

  (5) According to the present invention, the same effect as the above invention (1) can be obtained.

It is a figure which shows the structure of the hydrogen filling system which concerns on one Embodiment of this invention. It is a flowchart which shows the specific procedure of the authentication of the hydrogen tank at the time of filling start. It is a figure for demonstrating a preferable place for providing a storage medium among hydrogen tanks. It is sectional drawing of the nozzle | cap | die part of a hydrogen tank. It is a figure which shows typically the execution procedure of the communication filling in the case of performing the said collation process etc. by the station side in the hydrogen filling system in which bidirectional communication is possible.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a hydrogen filling system S according to the present embodiment. The hydrogen filling system S is configured by combining a fuel cell vehicle V that travels using hydrogen as a fuel gas and a hydrogen station 9 that supplies hydrogen gas to a hydrogen tank of the vehicle V. Hereinafter, the configuration on the hydrogen station 9 side will be described first, and then the configuration on the fuel cell vehicle V side will be described.

  The hydrogen station 9 includes a hydrogen storage tank and a dispenser 92 (not shown). In the hydrogen storage tank, hydrogen gas to be supplied to the vehicle V is stored at a high pressure. The dispenser 92 includes a hydrogen filling nozzle 93 that discharges the hydrogen gas supplied from the hydrogen storage tank, and a control device 94 that controls the flow rate of the hydrogen gas discharged from the hydrogen filling nozzle 93.

  When the hydrogen filling nozzle 93 is connected to the receptacle 38 provided in the vehicle V, the control device 94 depressurizes the hydrogen supplied from the hydrogen storage tank and supplies hydrogen gas from the hydrogen filling nozzle 93 at a predetermined flow rate. To do. The hydrogen gas supplied from the hydrogen filling nozzle 93 is filled in the hydrogen tank 31 of the vehicle V.

  The hydrogen filling nozzle 93 is provided with an infrared communication device 95 for communicating with the vehicle V. By connecting the hydrogen filling nozzle 93 to the receptacle 38, the infrared communication device 95 can transmit and receive data signals by infrared rays to and from the infrared communication device 5 described later provided in the vehicle V. When filling the vehicle V with hydrogen gas, the dispenser 92 can selectively execute two filling methods, a filling method called communication filling and a filling method called non-communication filling.

  The communication filling is a filling method in which the vehicle V is filled with hydrogen gas while communicating between the vehicle V and the station 9. In communication filling, the control device 94 receives a data signal including information related to the hydrogen tank 31 of the vehicle V by the infrared communication device 95, and fills the hydrogen tank 31 with hydrogen gas in a filling mode determined based on the data signal. To do. Based on the data signal received during communication filling, control device 94 sequentially calculates the filling rate of hydrogen in hydrogen tank 31 (hereinafter also referred to as “hydrogen SOC”) by a known method, and this hydrogen SOC is predetermined. When the full-filling threshold is exceeded, it is determined that the filling of hydrogen gas is completed, and the filling of hydrogen gas is terminated. In addition, when the temperature of the hydrogen tank reaches a predetermined failure temperature, when the data signal cannot be received, or when an abort signal described later is received during communication filling, the control device 94 is fully filled with hydrogen SOC. Even when the threshold value is not reached, it is desirable to interrupt or end the filling of hydrogen gas using the data signal. In the following description, an example in which the filling of hydrogen gas is terminated in response to receiving an abort signal will be described.

  This communication filling is called general communication filling depending on the type of information included in the data signal transmitted from the vehicle V to the station 9, that is, the type of information used in the filling control executed by the control device 94. It is divided into a filling method and a filling method called unique communication filling.

  In general communication filling, a data signal including state information including a temperature value, a pressure value, and the like of the hydrogen tank 31 is transmitted from the vehicle V side. In the present invention, the state information of the hydrogen tank is defined as a value that can be sequentially changed during filling of information related to the hydrogen tank 31 such as a temperature value and a pressure value of the hydrogen tank 31. The control device 94 receives the data signal including the state information of the hydrogen tank transmitted from the vehicle V, and fills the hydrogen gas in the filling mode determined according to the state of the hydrogen tank 31 at that time based on the data signal. .

  In the unique communication filling, from the vehicle V side, in addition to the above state information, unique information composed of a value representing the heat dissipation characteristics of the hydrogen tank 31 such as heat capacity, a capacity value of the hydrogen tank, and manufacturing information of the hydrogen tank, etc. A data signal including is transmitted. In the present invention, the unique information of the hydrogen tank is defined as a value that does not change during filling, unlike the above-described state information, among the information related to the hydrogen tank 31. The control device 94 receives the data signal including the state information and unique information of the hydrogen tank 31 transmitted from the vehicle V, and based on this data signal, not only the state of the hydrogen tank 31 at that time but also the future hydrogen tank 31. The temperature value, the pressure value, etc. are predicted, and hydrogen gas is filled in the filling mode determined according to the present and future conditions. As described above, in the specific communication filling, the control device 94 can fill the hydrogen while predicting the future state of the hydrogen tank 31, so that the temperature of the hydrogen tank 31 does not exceed the fail temperature during filling, while Compared to general communication filling, it can be filled more quickly.

  Non-communication filling is a filling method in which the vehicle V is filled with hydrogen without performing communication between the vehicle V and the station 9. In non-communication filling, the control device 94 fills the hydrogen tank 31 with hydrogen gas in a predetermined prescribed filling mode. Since the control device 94 cannot grasp the current state of the hydrogen tank 31 at the time of non-communication filling, the control device 94 has a lower pressure (that is, a low filling rate) than the communication filling so as not to cause overfilling or overheating during filling. ) To finish filling. Therefore, when comparing the above two communication fillings and non-communication fillings, the communication filling is performed while grasping the state of the hydrogen tank 31, so that the full filling or the vicinity thereof can be performed.

  The fuel cell vehicle V stores a hydrogen tank 31 that stores the hydrogen gas supplied from the station 9, and a fuel cell system that generates power using the hydrogen gas stored in the hydrogen tank 31 and travels using the generated power (see FIG. An infrared communication device 5 that transmits a data signal indicating the state of the hydrogen tank 31 to the infrared communication device 95 of the station 9 and a filling calculation ECU 6 that generates a data signal transmitted from the infrared communication device 5. And comprising.

  The hydrogen tank 31 is connected to the receptacle 38 by a hydrogen introduction pipe 39. That is, the hydrogen gas discharged from the hydrogen filling nozzle 93 connected to the receptacle 38 is filled into the hydrogen tank 31 through the hydrogen introduction pipe 39.

  A storage medium 33 is provided in the hydrogen tank 31. In the storage medium 32, in addition to unique information that can be specified at the time of manufacturing the hydrogen tank 31, such as a value representing the heat dissipation characteristics of the hydrogen tank 31, a capacity value of the hydrogen tank 31, and manufacturing information of the hydrogen tank, The associated password for authentication is recorded. As the storage medium 33, for example, an ID tag that generates a signal corresponding to the specific information, or a barcode or a two-dimensional code having a pattern corresponding to the specific information is used, but the present invention is not limited thereto. Any medium may be used as long as the unique information can be stored and the stored information can be read by the reading device 43.

  The communication calculation ECU 6 is a computer including a microcomputer, and includes a CPU (Central Processing Unit), storage media such as ROM and RAM, and electronic circuits such as various interfaces. In the ROM of the communication calculation ECU 6, unique information relating to the hydrogen tank that was mounted when the vehicle V was manufactured and an authentication code associated with the unique information are recorded. In accordance with the procedure shown in FIG. 2 later, the communication calculation ECU 6 determines whether or not the hydrogen tank 31 mounted on the vehicle V at that time is the same as the hydrogen tank specified by the unique information recorded in the ROM. After performing the hydrogen tank authentication process for confirming the above, a data signal to be transmitted to the station 9 via the infrared communication device 5 is generated in a manner corresponding to the result of the authentication process.

  A temperature sensor 41, a pressure sensor 42, and a reading device 43 are connected to the communication calculation ECU 6 as means for acquiring information related to the hydrogen tank 31 described above. The temperature sensor 41 detects the temperature of the hydrogen gas in the hydrogen tank 31 and transmits a signal substantially proportional to the detected value to the communication arithmetic ECU 6. The pressure sensor 42 detects the pressure in the hydrogen tank 31 and transmits a signal substantially proportional to the detected value to the communication arithmetic ECU 6. The reading device 43 reads information recorded in the storage medium 33 provided in the hydrogen tank 31 (unique information and password code of the hydrogen tank 31), and transmits a signal corresponding to the read information to the communication calculation ECU 6.

  The communication calculation ECU 6 is connected with a warning lamp 45 as means for notifying the user of the result of the approval process. The warning light 45 is provided at a place where the driver can visually recognize, for example, a meter panel in the passenger compartment, or at a place where the operator can visually recognize hydrogen gas filling outside the passenger compartment.

  The infrared communication device 5 includes, for example, an infrared LED and its driver. The driver blinks the infrared LED in a manner corresponding to the data signal and the abort signal generated by the communication calculation ECU 6. Thereby, a data signal including information (state information T, P and unique information ID) related to the hydrogen tank 31 is transmitted from the vehicle V to the station 9. Hereinafter, infrared communication between the vehicle V and the station 9 using the infrared communication devices 5 and 95 is referred to as Ir communication.

  FIG. 2 is a flowchart showing a specific procedure for authenticating the hydrogen tank at the start of filling. The process shown in FIG. 2 is executed by the communication calculation ECU when the communication calculation ECU is activated in the station. Note that the communication calculation ECU performs a preliminary operation by the user to start filling the hydrogen gas (for example, an operation in which the user opens a lid box that protects the receptacle, or a hydrogen filling nozzle of the hydrogen station is installed in the vehicle receptacle. It is triggered by the detection of an insertion operation or the like.

  First, in S1, the communication calculation ECU reads the password code recorded in the hydrogen tank by the reading device, and proceeds to S2. In S2, the communication calculation ECU collates the password code acquired from the hydrogen tank in S1 with the password code recorded in the ROM. In addition, when the personal identification code is associated with the unique information as described above, the act of reading the personal identification code and collating the personal identification code with another personal identification code is equivalent to the act of collating the identification information itself. .

  As a result of the collation in S2, if the two passwords match, the communication calculation ECU determines that the currently installed hydrogen tank is appropriate (authentication is established), and proceeds to S3. In S3, the communication calculation ECU generates a data signal including both the hydrogen tank state information obtained from the output of the temperature sensor and the pressure sensor and the unique information of the hydrogen tank, and transmits the data signal to the station via the infrared communication device. Send to. In response to receiving the data signal including the state information and the specific information, the station starts specific communication filling using both the state information and the specific information (S4).

  If the passwords do not match as a result of the collation in S2, the communication calculation ECU determines that the currently installed hydrogen tank is not appropriate (authentication is not established), and proceeds to S5. In S5, the communication calculation ECU turns on the warning lamp to notify the user that the authentication has not been established, that is, the mounted hydrogen tank is not appropriate, and proceeds to S6.

  In S6, the communication arithmetic ECU stops the transmission of the data signal to the station, in other words, stops the light emission of the LED of the infrared communication device. When the station cannot receive the data signal to be transmitted from the vehicle side, the station starts non-communication filling in which hydrogen gas is charged in a predetermined manner (S7).

  In addition, as shown in FIG. 2, the process performed when authentication of a hydrogen tank is not materialized is not restricted to said S6, S7. The processes S6 and S7 performed when the authentication is not established can be replaced with, for example, the following processes S6 ′, S7 ′ or S6 ″.

  In S6 ′, the communication calculation ECU transmits a data signal including the state information of the hydrogen tank obtained from the outputs of the temperature sensor and the pressure sensor and not including the unique information, and transmits the data signal to the station. The station starts general communication filling using the state information in response to receiving the data signal including the state information and not including the specific information (S7 ′). In S6 ″, the communication calculation ECU transmits an abort signal to the station. The station ends the filling of hydrogen gas in response to receiving this abort signal.

Next, with reference to FIGS. 3 to 4, a place where the storage medium of the hydrogen tank is provided will be described.
FIG. 3 is a diagram for explaining a preferable place for providing the storage medium in the hydrogen tank.

  As shown on the right side of FIG. 3, the storage medium is provided at a portion called a dome portion 31 a, a cylinder portion 31 b, a tangent portion 31 c, a bottom portion 31 d, and a base portion 31 e of the substantially cylindrical hydrogen tank 31. Anyway, anywhere. The case where the storage medium is provided in the base part 31e will be described in detail later with reference to FIG.

  The cross-sectional structure of the hydrogen tank 31 is shown on the left side of FIG. The wall portion of the hydrogen tank 31 is divided into a metal or resin liner, a CFRP reinforcing layer, and a decorative layer made of a plurality of materials in order from the inside toward the outside. FIG. 3 shows a case where the decorative layer is composed of a GFRP layer, a transparent resin layer, and a paint layer.

  For example, when an ID tag is used as a storage medium and information recorded on the ID tag is electromagnetically read by a reading device, the storage medium is a conductive material inside the surface of the outermost layer of the hydrogen tank. It is preferable to provide in a part other than the inside of the reinforcement layer comprised by CFRP. As shown in FIG. 3, it is possible to prevent the storage medium from being easily tampered by providing the storage medium inside the paint layer which is the outermost layer. Further, by providing a storage medium in a portion other than the inside of the reinforcing layer, information recorded on the storage medium can be read electromagnetically and appropriately by the reading device.

  Further, for example, when a bar code or a two-dimensional code is used as a storage medium, and the information recorded on the code is optically read by a reader, the storage medium is inside the outermost layer formed of a transparent resin or the transparent layer. Preferably, it is provided between the receiving layer and the inner layer made of GFRP. Accordingly, it is possible to prevent the storage medium from being easily tampered with while the information recorded in the storage medium is optically appropriately read by the reading device. In addition, as shown in FIG. 3, when using the optically read storage medium, the outermost layer of the hydrogen tank needs to be formed of a transparent material.

  FIG. 4 is a cross-sectional view of the cap portion 31 e of the hydrogen tank 31. An in-tank valve 31f that opens and closes when the hydrogen gas in the hydrogen tank 31 is supplied to the outside or when the hydrogen gas is filled into the hydrogen tank 31 from the outside is attached to the base 31e. Therefore, when the storage medium 33 is provided in the base part 31e, the reading device 43 can be provided in the in-tank valve 31f. In this case, the reading device 43 and the storage medium 33 are opposed to each other when the in-tank valve 31f is attached to the base 31e so that the information stored in the storage medium 33 can be read by the reading device 43. Is provided. Thus, by integrating the reading device 43 and the storage medium 33 by the in-tank valve 31f, it is possible to prevent the reading device 43 and the storage medium 33 from being easily falsified. 4 shows a case where the reading device 43 is provided in the in-tank valve 31f, the present invention is not limited thereto, and the reading device may be provided in the out-tank valve.

  As mentioned above, although one Embodiment of this invention was described, this invention is not restricted to these. For example, in the above-described embodiment, the case where the present invention is applied to a hydrogen filling system capable of unidirectional communication from the vehicle side to the station side has been described. However, the present invention is not limited to this, and both of them as shown in FIG. The present invention can also be applied to a hydrogen filling system S ′ capable of bidirectional communication. Further, in both cases of a system capable of one-way communication and a system capable of two-way communication, the subject that performs the collation processing may be a vehicle-side communication arithmetic ECU or a station-side control device. it can.

  FIG. 5 is a diagram showing a configuration of a hydrogen filling system S ′ capable of bidirectional communication. In the hydrogen filling system S ′, the vehicle V ′ and the station 9 ′ can transmit and receive data signals to and from each other via the respective communication devices 5 ′ and 95 ′.

First, the communication calculation ECU 6 ′ of the vehicle V ′ sends a data signal including two pieces of unique information, the unique information read from the fuel tank 31 and the unique information stored in the ROM of the communication calculation ECU, to the communication device 5 ′. To the station 9 'side.
Next, the control device 94 ′ of the station 9 ′ collates the received two pieces of specific information by the same procedure as S <b> 2 in FIG. 2, and determines whether or not the hydrogen tank mounted on the vehicle is appropriate. Execute authentication process to confirm. Then, when the authentication is established, the control device 94 ′ transmits a signal indicating that the unique communication filling is permitted to the vehicle V ′ side via the communication device 95 ′. In addition, when the authentication is not established, the control device 94 ′ transmits a signal indicating that general communication filling or non-communication filling is permitted to the vehicle V ′ side via the communication device 95 ′.

  Next, when the communication calculation ECU 6 ′ of the vehicle V ′ receives a signal indicating that the unique communication filling is permitted, a data signal including both the state information and the unique information is transmitted to start the unique communication filling. To start. In addition, when the communication calculation ECU 6 ′ receives a signal indicating that general communication filling is permitted, the communication arithmetic ECU 6 ′ starts transmission of a data signal including state information so as to start general communication filling, and permits non-communication filling. When the above signal is received, the transmission of the data signal is stopped. As described above, the same effect as that of the above-described embodiment can be obtained even if the main body that executes the matching process is the station-side control device 94 ′.

  In the above embodiment, whether or not the hydrogen tank is appropriate is verified by comparing the password code recorded in the communication calculation ECU with the password code recorded in the hydrogen tank. The present invention is not limited to this. For example, authentication of whether the hydrogen tank is appropriate may be performed by checking the unique information itself without using a password.
