Hydrogen supply system
A hydrogen supply system including: an attachable and detachable hydrogen tank; a hydrogen consumption device that consumes hydrogen of the hydrogen tank; and a control device is provided. The hydrogen consumption device includes an attaching-detaching mechanism that attaches and detaches the hydrogen tank with respect to the hydrogen consumption device. The attaching-detaching mechanism includes a motor that controls attaching and detaching of the hydrogen tank with respect to the hydrogen consumption device, and a hydrogen tank biasing mechanism that transmits a biasing force to the hydrogen tank. The control device performs stop control of stopping control of the motor of the attaching-detaching mechanism when abnormality is sensed in at least one of the hydrogen tank and the hydrogen consumption device in a state in which the hydrogen tank is connected to the hydrogen consumption device and the hydrogen is supplied from the hydrogen tank to the hydrogen consumption device.
1 . A hydrogen supply system comprising:
a hydrogen tank that is attachable and detachable;
a hydrogen consumption device that consumes hydrogen of the hydrogen tank; and
a control device, wherein:
the hydrogen consumption device includes an attaching-detaching mechanism that attaches and detaches the hydrogen tank with respect to the hydrogen consumption device;
the attaching-detaching mechanism includes a motor that controls attaching and detaching of the hydrogen tank with respect to the hydrogen consumption device, and a hydrogen tank biasing mechanism that transmits a biasing force to the hydrogen tank; and
the control device performs a stop control action comprising stopping the motor of the attaching-detaching mechanism when abnormality is sensed in at least one of the hydrogen tank and the hydrogen consumption device, in a state in which the hydrogen tank is connected to the hydrogen consumption device and the hydrogen is supplied from the hydrogen tank to the hydrogen consumption device.
2 . The hydrogen supply system according to claim 1 , wherein:
the attaching-detaching mechanism includes a lock portion that latches the hydrogen tank at a predetermined position when movement of the hydrogen tank is restricted;
the control device performs lock control of bringing the hydrogen tank to a lock state by the lock portion when the abnormality is sensed in at least one of the hydrogen tank and the hydrogen consumption device; and
the control device performs the stop control after performing the lock control.
3 . The hydrogen supply system according to claim 2 , wherein:
the attaching-detaching mechanism includes an attaching-detaching unit that allows the hydrogen tank to be attached and detached;
the attaching-detaching unit includes a movable portion that moves the hydrogen tank through control of the motor, and a fitting portion to be fitted to the hydrogen tank;
the movable portion includes an engagement recessed portion engageable with the lock portion; and
the lock portion is a lock pin.
4 . The hydrogen supply system according to claim 3 , wherein:
the hydrogen tank includes a first connection portion;
the fitting portion includes a second connection portion; and
at the time of fitting the hydrogen tank to the fitting portion, the first connection portion of the hydrogen tank and the second connection portion of the fitting portion are connected.
5 . The hydrogen supply system according to claim 4 , wherein:
the first connection portion is an on-off valve; and
the second connection portion is a push rod.
