The power stepped down by the step-down converter 25 may be directly supplied to the auxiliary machine without going through the auxiliary machine battery 75.

The secondary battery 17 is provided with a battery management system (BMS: Battery Management System) 18. For example, the battery management device 18 calculates the output voltage (battery voltage) of the secondary battery 17, the remaining capacity SOC, and the like, and outputs a signal indicating the information to the control device 30.

The drive motor 21 is driven by the supplied electric power to output the drive torque of the vehicle. The drive motor 21 is, for example, a three-phase AC motor, and is driven (power-driven) using the power supplied from the secondary battery 17 and the fuel cell 13 to generate a drive torque. Further, the drive motor 21 may have a function (regeneration function) as a generator that is regeneratively driven when the vehicle is decelerated and generates electricity by using the rotational torque of the drive wheels 23.

<2. Configuration example of hydrogen filling system>
Next, a configuration example of the hydrogen filling system according to the present embodiment will be described. FIG. 2 is a schematic view showing an example of the configuration of the hydrogen filling system 50 according to the present embodiment.

The hydrogen filling system 50 includes a receptacle 61, a switch 73, and a hydrogen filling management device 80. The receptacle 61 has a function as a connecting portion to which the filling nozzle 91 on the external hydrogen supply station side is connected. The receptacle 61 is provided at the tip of a pipe 62 connected to a hydrogen tank (11) (not shown). Further, the receptacle 61 includes a check valve (not shown) to prevent high-pressure hydrogen in the pipe 62 from being released to the outside when the filling nozzle 91 is removed. The receptacle 61 or the filling nozzle 91 may be provided with a lock mechanism capable of holding or releasing the connected state.

The receptacle 61 is provided, for example, in a lid box 55 provided behind the side surface of the vehicle body 53. The lid box 55 is opened or closed to the outside through the opening 57 of the body 53 by opening and closing the lid 51 attached via the hinge 51a. Further, the receptacle 61 is attached to a movable portion 63 displaceably provided in the lid box 55. The movable portion 63 is configured to be displaceable in the depth direction with the opening 57 on the front side.

The movable portion 63 shown in FIG. 2 is a plate-shaped movable portion 63, and one or more springs 65 are arranged between the movable portion 63 and the bottom portion 55a of the lid box 55. Both ends of the spring 65 are fixed to the movable portion 63 and the bottom portion 55a of the lid box 55, and the movable portion 63 is urged toward the opening 57 side by the spring 65. A waterproof means for suppressing the intrusion of rainwater into the internal space behind the movable portion 63 in the lid box 55 may be provided between the periphery of the movable portion 63 and the inner surface of the lid box 55. Further, a drain port for discharging rainwater or the like that has entered the lid box 55 may be provided in the lower part of the space on the opening 57 side of the movable portion 63 in the lid box 55.

By pushing the movable portion 63 and the receptacle 61 toward the bottom 55a side of the lid box 55, the movable portion 63 and the receptacle 61 move toward the bottom 55a side against the urging force of the spring 65. On the other hand, by weakening the force pushing the movable portion 63 and the receptacle 61 toward the bottom portion 55a, the movable portion 63 and the receptacle 61 move toward the opening 57 side by the urging force of the spring 65.

The movable unit 63 is provided with a vehicle-side communication unit 71. The vehicle-side communication unit 71 communicates with the nozzle-side communication unit 93 provided in the filling nozzle 91 on the hydrogen supply station side. The vehicle-side communication unit 71 is, for example, an infrared communication unit, and transmits an infrared signal including predetermined control information to the nozzle-side communication unit 93 configured to be able to receive infrared rays. The vehicle-side communication unit 71 and the nozzle-side communication unit 93 are not particularly limited in terms of communication means and installation position as long as they are configured to be able to communicate with each other. However, it is preferable that the vehicle-side communication unit 71 and the nozzle-side communication unit 93 can communicate only when the filling nozzle 91 is connected to the receptacle 61.

Further, the movable portion 63 is provided with a proximity sensor 72 for detecting the distance between the receptacle 61 or the movable portion 63 and the filling nozzle 91. The proximity sensor 72 is used to detect that the filling nozzle 91 has been removed from the receptacle 61. As a result, it is possible to timely detect that the filling nozzle 91 has been removed from the receptacle 61. The position where the proximity sensor 72 is provided is not limited to the movable portion 63, and may be an appropriate position inside the lid box 55.

It is detected that the lid 51 is closed by using an open / close switch that generates an electric signal when the lid 51 is opened and closed, a rotation angle sensor that detects the rotation angle of the lid 51 when the lid 51 is opened and closed, and the like. Therefore, it may be determined that the filling nozzle 91 has been removed. As a result, it is possible to detect that the filling nozzle 91 has been reliably removed.

The switch 73 is provided in the internal space on the bottom 55a side of the lid box 55 separated by the movable portion 63. In the example shown in FIG. 2, the switch 73 is fixed to the bottom portion 55a of the lid box 55. In the present embodiment, the switch 73 is configured as a momentary switch and is closed in a state where the movable portion 63 is pushed toward the bottom 55a side of the lid box 55, while the movable portion 63 is located on the opening 57 side. It becomes an open state in the state.

The switch 73 is provided in the middle of an electric circuit connecting the hydrogen filling management device 80 and the auxiliary battery 75 as a power source for supplying electric power to the hydrogen filling management device 80. When the switch 73 is closed, electric power is supplied from the auxiliary battery 75 to the hydrogen filling management device 80 via the switch 73. On the other hand, when the switch 73 is opened, the power supply from the auxiliary battery 75 to the hydrogen filling management device 80 via the switch 73 is cut off.

A stopper 69 is fixed to the bottom portion 55a of the lid box 55. The stopper 69 defines the maximum moving range of the movable portion 63 that moves toward the bottom portion 55a. The width of the stopper 69 along the depth direction of the lid box 55 corresponds to the width of the switch 73. That is, the width of the stopper 69 is designed so that when the movable portion 63 is pushed toward the bottom portion 55a and the switch 73 is pushed, the switch 73 is not damaged by the pushing pressure. The urging force of the spring 65 or the amount of displacement until the movable portion 63 pushes the switch 73 is the force when the user connects the filling nozzle 91 to the receptacle 61 in a normal operation, and the movable portion 63 moves the switch 73. It is preferable that it is set so that it can be pressed.

Further, when a waterproof means is provided between the movable portion 63 and the inner surface of the lid box 55, or when a drain port is provided in the lower part of the space on the opening 57 side of the movable portion 63, the opening is opened. Even when rainwater or the like enters the lid box 55 from the portion 57, the switch 73 is prevented from being exposed to water. Therefore, damage to the switch 73 and electric leakage can be prevented.

The hydrogen filling management device 80 includes a power supply circuit 81 and a control circuit 83. The hydrogen filling management device 80 is connected to the auxiliary battery 75 via a first power supply path 85 provided with a switch 73 and a second power supply path 87 provided with a self-power holding relay 77. ing. The switch 73 is a momentary switch as described above, while the self-power holding relay 77 relays the relay unless the coil provided inside is energized to temporarily close the relay and then the energization to the coil is cut off. Keep closed.

The power supply circuit 81 controls the supply of electric power to the hydrogen filling management device 80. As described above, when the switch 73 is closed, power is supplied from the auxiliary battery 75 to the hydrogen filling management device 80 via the first power supply path 85. The power supply circuit 81 is supplied with electric power to activate the hydrogen filling management device 80.

In the activated state of the hydrogen filling management device 80, the control circuit 83 transmits control information including pressure information of the hydrogen tank 11 to the nozzle side communication unit via the vehicle side communication unit 71 provided in the receptacle 61 or the movable unit 63. Send to 93. The control device of the hydrogen supply station that receives the pressure information via the nozzle-side communication unit 93 controls the supply of high-pressure hydrogen to the hydrogen tank 11. Specifically, the control device of the hydrogen supply station controls at least one of the pressure and the flow rate of the high-pressure hydrogen supplied to the hydrogen tank 11.

Further, in the control circuit 83, when the switch 73 is closed, power is supplied from the auxiliary battery 75 to the hydrogen filling management device 80 via the first power supply path 85, and the power supply circuit 81 manages the hydrogen filling. When the device 80 is started, the coil of the self-power holding relay 77 is energized to keep the self-power holding relay 77 in the closed state. When the self-power holding relay 77 is closed, power is supplied from the auxiliary battery 75 to the hydrogen filling management device 80 via the second power supply path 87, so that the switch 73 is in the open state. Even so, the supply of electric power to the hydrogen filling management device 80 is maintained.

Further, when the filling nozzle 91 is removed from the receptacle 61, the control circuit 83 stops energizing the coil of the self-power holding relay 77 and opens the relay of the self-power holding relay 77. As a result, the supply of electric power to the hydrogen filling management device 80 is cut off. The control circuit 83 can detect, for example, that the filling nozzle 91 has been removed from the receptacle 61 based on the sensor signal of the proximity sensor 72.

Further, when the hydrogen filling management device 80 is activated, the control circuit 83 causes a vehicle control device (30) (not shown) to prohibit the vehicle from traveling. This makes it possible to prevent the vehicle from being accidentally started running during the filling operation of the high-pressure hydrogen into the hydrogen tank 11. Further, the control circuit 83 permits the vehicle control device (30) to travel the vehicle when the filling nozzle 91 is removed. For example, the vehicle control device 30 may be configured to detect an electric signal indicating that the hydrogen filling management device 80 is in the activated state. As a result, the vehicle control device 30 prohibits the execution of the control for driving the vehicle while the electric signal is detected, while the control for driving the vehicle is permitted when the electric signal is no longer detected. It can be determined that it has been done.

<3. Operation example of hydrogen filling system>
Next, an operation example of the hydrogen filling system 50 according to the present embodiment will be described with reference to FIGS. 2 to 4.

FIG. 3 is a schematic view showing a state in which the filling nozzle 91 is connected to the receptacle 61 to activate the hydrogen filling management device 80. When filling the hydrogen tank 11 with high-pressure hydrogen, the user opens the lid 51, connects the filling nozzle 91 to the receptacle 61, and pushes in the movable portion 63 to which the receptacle 61 is attached as it is. As a result, the spring 65 arranged between the movable portion 63 and the bottom portion 55a of the lid box 55 is compressed, and the switch 73 is pushed by the displacement of the movable portion 63, and the switch 73 is closed. At this time, the movable portion 63 does not displace beyond the position where it comes into contact with the stopper 69, and the switch 73 is protected.

When the switch 73 is closed, power is supplied from the auxiliary battery 75 to the hydrogen filling management device 80 via the first power supply path 85. As a result, the power supply circuit 81 of the hydrogen filling management device 80 activates the hydrogen filling management device 80. When the hydrogen filling management device 80 is activated, the control circuit 83 of the hydrogen filling management device 80 energizes the coil of the self-power holding relay 77 and keeps the self-power holding relay 77 in the closed state. Further, the control circuit 83 detects the pressure of the hydrogen tank 11 and transmits a signal indicating the pressure information to the hydrogen supply station via the vehicle-side communication unit 71. As a result, the control device of the hydrogen supply station fills the high-pressure hydrogen while controlling at least one of the pressure and the flow rate of the high-pressure hydrogen to be filled in the hydrogen tank 11.

FIG. 4 is a schematic view showing a state in which the pushing operation of the movable portion 63 is released after the filling nozzle 91 is connected to the receptacle 61. When the pushing operation of the movable portion 63 is released, the movable portion 63 is returned to the opening 57 side by the urging force of the spring 65 arranged between the movable portion 63 and the bottom portion 55a of the lid box 55. As a result, the switch 73 configured as a momentary switch is switched to the open state, and the power supply from the auxiliary battery 75 to the hydrogen filling management device 80 via the first power supply path 85 is cut off.

However, since the self-power holding relay 77 is maintained in the closed state, the power supply from the auxiliary battery 75 to the hydrogen filling management device 80 is maintained via the second power supply path 87, and the hydrogen filling management is performed. Communication from the device 80 to the hydrogen supply station and filling of high-pressure hydrogen from the hydrogen supply station to the hydrogen tank 11 are continued. During this time, the vehicle is prohibited from traveling by the vehicle control device 30.

When the filling of high-pressure hydrogen from the hydrogen supply station to the hydrogen tank 11 was completed and the filling nozzle 91 was removed from the relay 61, the control circuit 83 removed the filling nozzle 91 based on the sensor signal of the proximity sensor 72. Is detected, and the energization of the self-power holding relay 77 to the coil is stopped. As a result, as shown in FIG. 2, both the switch 73 and the self-power holding relay 77 are opened, and the start of the hydrogen filling management device 80 is stopped. When the start of the hydrogen filling management device 80 is stopped, the prohibition of traveling of the vehicle by the vehicle control device 30 is lifted, and the vehicle can travel.

As described above, in the hydrogen filling system 50 according to the present embodiment, the switch 73 is operated to fill hydrogen by further pushing the movable portion 63 to which the receptacle 61 is attached in the state where the filling nozzle 91 is connected to the receptacle 61. The management device 80 is activated. Therefore, even if it takes a long time from the opening of the lid 51 to the connection of the filling nozzle 91 to the receptacle 61, the power consumption of the auxiliary battery 75 can be suppressed during that time. .. Therefore, it is possible to suppress a situation in which the power of the auxiliary battery 75 is exhausted and the vehicle cannot start traveling. Since such a pushing operation occurs in association with the operation when the user connects the filling nozzle 91 to the receptacle 61, the user performs a special operation to activate the hydrogen filling management device 80 without applying force. be able to.

The hydrogen filling system 50 according to the present embodiment is configured to prohibit the vehicle from traveling by the vehicle control device 30 while the hydrogen filling management device 80 is activated. Therefore, it is possible to prevent the vehicle from accidentally starting traveling while the filling nozzle 91 is connected to the receptacle 61 and filled with high-pressure hydrogen. Further, in the hydrogen filling system 50 according to the present embodiment, the start of the hydrogen filling management device 80 may be stopped by detecting that the filling nozzle 91 has been removed from the receptacle 61. Therefore, it is possible to prevent the vehicle from accidentally starting traveling while the filling nozzle 91 is connected to the receptacle 61 and filled with high-pressure hydrogen.

Further, in the hydrogen filling system 50 according to the present embodiment, the switch 73 is a momentary switch, and the control circuit 83 closes the self-power holding relay 77 when the switch 73 is closed, and then the switch 73. The power supply to the hydrogen filling management device 80 can be maintained even when is in the open state. Therefore, by using a momentary switch as the switch 73, it is possible to easily configure the switch 73 that can be operated with the filling nozzle 91 and the receptacle 61 connected to each other.

Further, in the hydrogen filling system 50 according to the present embodiment, when the proximity sensor 72 is used to detect that the filling nozzle 91 has been removed from the receptacle 61, the lid 51 may not be closed due to an external force. Even if there is, since the start of the hydrogen filling management device 80 can be stopped, it is possible to prevent the charging rate of the auxiliary battery 75 from being significantly lowered and the prohibition of traveling of the vehicle from being lifted.
