Description

  The present invention relates to a fuel cell vehicle.

  2. Description of the Related Art An electric vehicle is known that includes a fuel tank that stores fuel and a connector receiver that is connected to the fuel tank and opens on the surface of the vehicle body.

  By connecting the connector of the hydrogen supply device to the connector receiving portion, fuel is supplied from the hydrogen supply device to the electric vehicle. The connector receiving portion is covered with a fuel lid provided on the vehicle body.

  When the fuel cell is in operation, the conventional electric vehicle does not open the fuel lid even if an instruction to open the fuel lid is input to replenish the fuel.

  The conventional electric vehicle cannot supply fuel while the fuel cell is in operation, that is, in a state where it is activated. Therefore, in the conventional electric vehicle, when refueling at the place where the hydrogen supply device is installed, so-called hydrogen station, the fuel cell stop process is terminated, the connector of the hydrogen supply device is connected to the connector receiving portion, A series of steps of refueling, disconnecting the connector of the hydrogen supply device from the connector receiving portion, and completing the start-up process of the fuel cell is required. Each process takes time, and the entire refueling takes a considerable amount of time.

  Comparing such a fuel replenishment process of an electric vehicle and a fuel replenishment process of a gasoline vehicle, the start-up process of the fuel cell after refueling extends the waiting time of the user and decreases convenience.

  Further, since the conventional electric vehicle is stopped and started every time fuel is replenished, the deterioration of the fuel cell is promoted.

  Further, since the conventional electric vehicle is replenished with the fuel cell stopped, self-diagnosis including a leak check of the filling system cannot be performed. If a self-diagnosis is performed in the process of starting up the fuel cell after refueling, the user's standby time will be even longer.

  Furthermore, in the conventional electric vehicle, the temperature of the fuel cell is decreased and the fuel cell is dried during the period from the stop to the restart of the fuel cell. In order to solve these problems, the restart process of the fuel cell requires more time, and the amount of fuel consumed in the restart increases.

  Therefore, the present invention improves the convenience by shortening the fuel replenishment time, suppresses deterioration of the fuel cell due to repeated stop and restart, and suppresses fuel consumption accompanying fuel replenishment. Propose.

  In order to solve the above problems, a fuel cell vehicle according to the present invention includes a fuel cell that generates electricity by reacting fuel and oxygen in the air, a storage tank that stores the fuel, and a fuel that fills the storage tank. A charging system for guiding the fuel cell, and a fuel cell control device for operating the fuel cell when the fuel tank is filled with the fuel.

  According to the present invention, the fuel cell vehicle is improved in convenience by shortening the fuel replenishment time, the deterioration of the fuel cell due to repeated stop and restart, and the fuel consumption accompanying the fuel replenishment is suppressed. Can provide.

In other words, the lid opening / closing detection switch 86 is a specific example of the filling operation sensor 87. The filling operation sensor 87 can also detect a filling end operation.

  Next, fuel filling control by the fuel filling system 69 will be described.

  FIG. 5 is a flowchart of fuel filling control of the fuel cell vehicle according to the embodiment of the present invention.

  As shown in FIG. 5, the fuel cell control device 52 of the fuel cell vehicle 1 according to the present embodiment operates the fuel cell 2 when filling the fuel tank 15 with fuel.

  Further, when the fuel cell 2 is stopped, the fuel cell control device 52 activates the fuel cell 2 when the filling operation sensor 87 detects the filling start operation.

  Furthermore, when the fuel cell 2 is already in operation, the fuel cell control device 52 pauses the fuel cell 2 when the filling operation sensor 87 detects a filling start operation. The fuel cell control device 52 also stops the fuel cell 2 even when the fuel cell 2 is activated because the filling operation sensor 87 detects the filling start operation. Even when the fuel cell 2 is at rest, the fuel cell 2 generates power and maintains the voltage, while stopping the output of power. Note that the fuel cell 2 that is stopped stops the output of power, but depending on the state of the fuel cell 2, at least the output for generating the driving force, that is, the supply of power to the motor 3 is stopped. Since the fuel cell 2 is generating power even during the pause, the power management device 17 stops supplying power to the motor 3 that generates the driving force, but may allow charging of the secondary battery 16. it can. However, when the fuel cell 2 is in a suspended state or in a state in which the stopped fuel cell 2 has started, the output of all electric power is stopped.

  Furthermore, the fuel cell control device 52 performs a self-diagnosis when the filling operation sensor 87 detects a filling start operation.

  Further, the fuel cell control device 52 suppresses the supply of electric power required for traveling until the filling operation sensor 87 detects a filling end operation. That is, the fuel cell control device 52 (or the power management device 17) permits the fuel cell 2 to operate while prohibiting the vehicle from running until the filling operation sensor 87 detects the filling end operation.

  Here, regarding the fuel filling control, when the fuel cell vehicle 1 that is currently traveling is stopped and fuel is supplied, that is, when the fuel tank 2 is filled with fuel immediately after the fuel cell 2 is still in operation, The case where the vehicle is parked, the ignition key 77 of the fuel cell vehicle 1 is turned off, and the fuel cell 2 is stopped will be described separately.

  First, a description will be given of a case where the fuel cell vehicle 1 that is actually running is stopped and the fuel cell 2 is still in operation and the fuel tank 15 is filled with fuel.

  As shown in FIG. 5, when the fuel cell vehicle 1 stops and the main switch is turned off (turned off) (step S1), the fuel cell control device 52 causes the fuel cell 2 to transition to the post-processing mode and Post-processing for stopping the operation of the battery 2 is started (step S2). The fuel cell 2 in the post-processing mode prohibits power supply to the motor 3, that is, prohibits the fuel cell vehicle 1 from traveling. Further, the fuel cell 2 in the post-processing mode prohibits the fuel tank 15 from being filled with fuel. Prohibition of fuel filling to the fuel tank 15 is processed at the hydrogen station HSS based on a prohibition command transmitted to the hydrogen station HSS via the transmitter 73. Further, prohibition of fuel filling into the fuel tank 15 may be processed by closing the fuel filling source valve 58.

  The fuel cell control device 52 monitors the filling operation sensor 87 until the post-processing of the fuel cell 2 is completed (No in step S3), and determines whether or not a filling start operation has been performed (step S4). Specifically, the fuel cell control device 52 monitors the lid open / close detection switch 86 until the post-processing of the fuel cell 2 is completed (No in step S3), and determines whether or not a filling start operation has been performed. (Step S4).

  When the filling start operation has not been performed (No in step S4), that is, when the filling operation sensor 87 has not detected the filling start operation, in other words, the lid opening / closing detection switch 86 detects the opening operation of the fuel filling port lid 62. If not, the fuel cell control device 52 monitors the ignition key 77 and determines whether or not the ignition key 77 has been turned on (ON operation) (step S5).

  When the filling start operation is not performed (No at Step S4) and the ignition key 77 is turned on (ON operation) (Step S5 Yes), the fuel cell control device 52 interrupts the post-processing of the fuel cell 2. Then, the fuel cell 2 is shifted from the post-processing mode to the traveling phase (step S6). The fuel cell vehicle 1 can run.

  The fuel cell 2 in the traveling phase generates power so that the fuel cell vehicle 1 can travel. The travel phase includes a travel start mode, a travel start waiting mode, a travel mode, a travel end mode, and a travel abnormality mode. When an abnormality occurs in the travel start mode, the travel start waiting mode, and the travel mode, the fuel cell 2 transits to the travel end mode via the travel abnormality mode.

  When the filling start operation is not performed (No at Step S4) and the ignition key 77 is not turned on (ON operation) (No at Step S5), that is, when the ignition key 77 remains off (OFF), the fuel cell control is performed. The device 52 returns to step S3. In this case, the fuel cell 2 is in the post-processing mode and continues the post-processing.

  Steps S4 and S5 are repeated in a time shorter than the time required for the post-processing of the fuel cell 2. If the post-processing of the fuel cell 2 is completed without performing the filling start operation (No at Step S4) and the ignition key 77 being turned on (ON operation) (No at Step S5) (Yes at Step S3). The fuel cell control device 52 stops the fuel cell 2 (step S7).

  When the fuel cell 2 stops, the fuel cell 2 shifts from the post-processing mode to the system end mode, and stops after the system end mode. The stopped fuel cell 2 is in the phase determination mode. The fuel cell 2 in the phase determination mode monitors whether or not the ignition key 77 is turned on and the filling operation sensor 87 detects a filling start operation.

  On the other hand, when the filling start operation is performed (Yes in step S4), that is, when the filling operation sensor 87 detects the filling start operation, in other words, the lid opening / closing detection switch 86 detects the opening operation of the fuel filling port lid 62. In this case, the fuel cell control device 52 causes the fuel cell 2 to transition to the filling phase. The filling phase includes a filling start-up mode, a filling mode, a filling end mode, and a filling abnormality mode. The fuel cell 2 in the filling phase shifts to the filling activation mode and starts self-diagnosis of the fuel cell 2 (step S8).

  As a result of the self-diagnosis, when there is no abnormality in the fuel cell 2, in other words, when the self-diagnosis result is normal (No in step S9), the fuel cell control device 52 interrupts the post-processing of the fuel cell 2, and the fuel cell 2 Is changed to the filling mode, and the fuel cell 2 is stopped (step S10). That is, the fuel cell 2 in the filling mode is at rest.

  The fuel cell control device 52 transmits a filling permission signal from the transmitter 73 to the receiver 204 of the hydrogen station HSS after the fuel cell 2 is stopped, in other words, after the fuel cell 2 is changed to the filling mode. S11). The hydrogen station HSS that has received the filling permission signal fills the fuel tank 15 with fuel (step S12).

  While the fuel tank 15 is being filled with fuel, the fuel cell control device 52 performs measurement values of the temperature sensor 75, the voltage sensor 76, and the pressure sensor 85 related to the fuel cell 2, the temperature sensor 78 related to the fuel tank 15, and Based on the measured value of the pressure sensor 81, it is determined whether or not there is an abnormality in fuel filling (step S13). If there is no abnormality in the filling of fuel (No in step S13), the fuel cell control device 52 monitors the filling operation sensor 87 and determines whether or not a filling end operation has been performed (step S14). The fuel cell control device 52 returns to step S11 from the transmitter 73 to the receiver 204 of the hydrogen station HSS until the filling end operation is performed, in other words, while the filling end operation is not performed (No in step S14). Continue sending permission signals.

  On the other hand, when the filling end operation is performed (Yes in step S14), that is, when the filling operation sensor 87 detects the filling end operation, in other words, the lid opening / closing detection switch 86 detects the closing operation of the fuel filling port lid 62. In this case, the fuel cell control device 52 returns from the filling mode to the step S2 through the filling end mode, and transitions to the post-processing mode of the fuel cell 2 (step S2).

  If the result of the self-diagnosis (step S8) is that the fuel cell 2 is abnormal (Yes in step S9), or if there is an abnormality in fuel filling (step S13 Yes), the fuel cell control device 52 Transition to the abnormal mode, the shutoff valve 59a of the fuel supply source valve 59 is closed (step S15), and the fuel supply to the fuel cell 2 is prohibited.

  The fuel cell control device 52 prohibits the supply of fuel to the fuel cell 2, and then transmits a filling prohibition signal from the transmitter 73 to the receiver 204 of the hydrogen station HSS (step S16). At least one of the fuel cell vehicle 1 and the hydrogen station HSS is provided with a warning lamp (not shown), which is turned on (step S17). When the fuel cell vehicle 1 includes a warning light, the warning light is included in instruments (not shown) provided at the base of the handle 57. When the hydrogen station HSS is provided with a warning light, the warning light is included in the instruments (not shown) of the dispenser 202.

  The fuel cell control device 52 returns to step S16 from the transmitter 73 to the receiver 204 of the hydrogen station HSS until the filling end operation is performed, in other words, while the filling end operation is not performed (No in step S18). Continue sending prohibition signals.

  On the other hand, when the filling end operation is performed (Yes in step S18), that is, when the filling operation sensor 87 detects the filling end operation, in other words, the lid opening / closing detection switch 86 detects the closing operation of the fuel filling port lid 62. In this case, the fuel cell control device 52 stops the fuel cell 2 from the abnormal filling mode to the post-processing mode and the system end mode (step S19). The stopped fuel cell 2 transitions to the phase determination mode.

  Next, a case where the fuel tank 15 is filled with fuel while the ignition key 77 of the fuel cell vehicle 1 is turned off and the fuel cell 2 is stopped will be described. This case corresponds to the case where the fuel tank 15 is filled with fuel after the fuel cell 2 is stopped in step S7.

  As shown in FIG. 5, the fuel cell control device 52 monitors the filling operation sensor 87 and starts filling even when the ignition key 77 is turned off and the fuel cell 2 is stopped (step S20). It is determined whether or not an operation has been performed (step S21). Specifically, the fuel cell control device 52 monitors the lid opening / closing detection switch 86 while the fuel cell 2 is stopped (step S20), and determines whether or not a filling start operation has been performed (step S20). S21).

  When the filling start operation is performed (Yes in step S21), that is, when the filling operation sensor 87 detects the filling start operation, in other words, when the lid opening / closing detection switch 86 detects the opening operation of the fuel filling port lid 62. The fuel cell control device 52 shifts to the filling start mode of the filling phase, starts the fuel cell 2 (step S22), opens the shutoff valve 59a of the fuel supply source valve 59 (step S23), and goes to the fuel cell 2. Allows the supply of fuel. Thereafter, the fuel cell control device 52 proceeds to the above-described step S8, stops the fuel cell 2 in step S10, reaches the traveling phase (step S6) or stops the fuel cell 2 (step S7) through step S14.

  When the ignition key 77 is entered (step S31), the fuel cell control device 52 activates the fuel cell 2, transits to the travel activation mode of the travel phase, activates the fuel cell 2 (step S32), and supplies fuel. The shutoff valve 59a of the original valve 59 is opened (step S33), and the fuel cell 2 is shifted to the travel start waiting mode through a self-diagnosis.

  The fuel cell vehicle 1 according to the present embodiment operates the fuel cell 2 when the fuel tank 15 is filled with fuel. Therefore, the fuel cell vehicle 1 does not need to stop the fuel cell 2 before filling with fuel. That is, the fuel cell vehicle 1 does not require time for stopping the fuel cell 2 before filling with fuel. The fuel cell vehicle 1 can start fuel filling at an early stage. Further, the fuel cell vehicle 1 can perform self-diagnosis of the fuel cell 2 while the fuel is being filled. The fuel cell vehicle 1 does not need to restart the fuel cell 2 after completing the fuel filling, and can start early. Further, the fuel cell vehicle 1 reduces the number of times the fuel cell 2 is stopped and started as the fuel is filled, and suppresses the deterioration of the cell stack 51.

  Further, the fuel cell vehicle 1 according to the present embodiment activates the fuel cell 2 when the filling operation sensor 87 detects a filling start operation. Therefore, the fuel cell vehicle 1 can perform self-diagnosis of the fuel cell 2 while the fuel cell vehicle 1 is being filled with fuel. The fuel cell vehicle 1 does not need to restart the fuel cell 2 after completing the fuel filling, and can start early.

  Furthermore, the fuel cell vehicle 1 according to the present embodiment pauses the fuel cell 2 when the filling operation sensor 87 detects the filling start operation. Therefore, the fuel cell vehicle 1 can perform self-diagnosis of the fuel cell 2 before filling the fuel and before stopping the fuel cell 2. The self-diagnosis does not need to be performed again before traveling, and the fuel cell vehicle 1 can start at an early stage by omitting the self-diagnosis immediately before starting traveling after the completion of fuel filling.

  Furthermore, the fuel cell vehicle 1 according to the present embodiment includes a fuel cell 2 that maintains the voltage during the pause and stops the output of electric power. Therefore, the fuel cell vehicle 1 can maintain the cell stack 51 in a good state for traveling. Therefore, the fuel cell vehicle 1 can start early after completing the fuel filling.

  Further, the fuel cell vehicle 1 according to the present embodiment performs self-diagnosis when the filling operation sensor 87 detects a filling start operation. Therefore, the fuel cell vehicle 1 improves filling safety.

  Furthermore, the fuel cell vehicle 1 according to the present embodiment suppresses the supply of electric power until the filling operation sensor 87 detects a filling end operation. Therefore, the fuel cell vehicle 1 does not start to run during fuel filling. Therefore, the fuel cell vehicle 1 improves the safety at the time of filling.

  Therefore, according to the fuel cell vehicle 1 of the present invention, the convenience is improved by shortening the fuel replenishment time, the deterioration of the fuel cell due to repeated stop and restart, and the fuel accompanying the fuel replenishment Consumption is suppressed.

  The control at the time of fuel filling described above is a precondition that the main switch is inserted into the key cylinder of the fuel cell vehicle 1 and turned off. Control at the time of fuel filling can prevent erroneous operation and mischief, and can reflect the user's intention of fuel filling. When fuel filling is attempted without turning off the main switch, the control at the time of fuel filling disables the opening operation of the fuel filling port lid 62 and prohibits the opening of the fuel filling port lid 62, thereby causing an erroneous operation. It can also prevent and alert. Furthermore, the control at the time of fuel filling does not prohibit the opening of the fuel filling port lid 62, and even when an attempt is made to fill the fuel without turning off the main switch, the fuel is linked with the detection of the filling operation sensor 87. You may make the battery 2 into a dormant state (filling mode). In this case, not only the filling end operation but also another operation or the like is set as a condition for transitioning to the travel mode after the fuel filling is completed, thereby preventing erroneous operation and improving safety.
