The present application provides a method, device and system for automatically fueling a vehicle. The method includes: determining fuel amount to be filled according to the information of vehicle status and the driving route of the vehicle; assigning a fueling device which conforms to a preset position rule to the vehicle according to the current position of the vehicle and the preset position rule; sending a feedback message carrying position information of the fueling device to the vehicle, so that the vehicle drives to the fueling device indicated by a position of the fueling device; and sending information of the fuel amount to be filled and the information of the identifier of the vehicle to the fueling device so that the fueling device offers fuel to the vehicle indicated by the identifier of the vehicle according to the information of the fuel amount to be filled.

Data are collected on a turbidity of a fuel tank at each of a plurality of fueling stations. A fueling station is selected based on the collected data. A vehicle is moved to the selected fueling station.

A system, methods, and apparatus for preventing receptacle overfilling are presented. The system can include a sensor member configured to couple with a receptacle and sense a material level within the receptacle, such as via a sight glass of the receptacle. The system can include a controller in operable communication with the sensor member and configured to instantiate the shutoff of material flow from a material dispensing system if a particular material level is detected by the sensor member. The system can include an intermediate member configured to relay communications between the sensor member and the controller. The intermediate member can be coupled to a fluid line and can further act as a holster for the sensor member, such as by facilitating the coupling of the sensor member to the intermediate member and/or the fluid line.

The present disclosure provides a system and a method for guiding hydrogen charging, which may estimate a remaining hydrogen chargeable amount (remaining hydrogen storage amount), a charging time, and the like of a hydrogen charging station, and provide the estimated information to another vehicle to be charged through an Internet network when a driver charges hydrogen in a hydrogen tank of his/her fuel cell vehicle at the hydrogen charging station, such that the driver of the vehicle to be charged may recognize a maximum chargeable amount and a required charging time for a hydrogen tank of a vehicle to be charged for each hydrogen charging station, thereby allowing the fuel cell vehicles to visit the hydrogen charging station and smoothly charge hydrogen.

A robotic system for fueling or charging a vehicle having a vehicle connector, the robotic system including a robotic arm having a plurality of sequentially arranged articulated links and at least one group of operating cables extending from a proximal end of the arm to terminate at a control link, for controlling the position of that link, the cables each having a path comprising a passage in each successive more proximal link for closely receiving the cable, a flexible conduit operably connected with the robotic arm for delivering a fluid or an electrical current, respectively, to a vehicle, the conduit being connected to a source at a first end and a delivery connector at a second end, and a control system for operating the robotic arm and the hose or cable, wherein the control system directs the robotic arm to engage the vehicle connector with the delivery connector and, upon engagement of the vehicle connector and delivery connector, the control system relaxes the robotic arm to an under-constrained condition.

A float probe configured to regulate fluid flow into a fluid container is disclosed. The float probe comprises an upper assembly having one or more outlets, a plurality of rods extending from the upper assembly to a lower assembly and a float assembly disposed between the upper assembly and the lower assembly. A first distal end of the rods is coupled to the upper assembly and a second distal end of the rods is coupled to the lower assembly. The rods extend along an outer surface of the float assembly and the float assembly is movable along the rods between a first position proximate to the upper assembly and a second position proximate to the lower assembly. The float assembly prevents fluid flow out of the outlets when disposed in the first position.

A gravity-fed fuel delivery system is provided. A central storage tank holds fuel to re-supply a number of pump trucks or other mechanized equipment, such as on a hydraulic fracturing location, and can be selectively raised or lowered. Hoses or other conduits extend from the central storage tank to individual fuel tanks of the equipment to be refueled. Adapters allow connection of the distal end of each hose or conduit to an inlet opening of a fuel tank. A float valve assembly senses when fuel inside an individual fuel tank is below a predetermined level, thereby mechanically opening a valve assembly to permit fluid to flow from the central storage tank, through a conduit, through the float valve assembly and into the fuel tank.

A robotic servicing system. The robotic servicing system includes an evacuation system, a refill system and a robotic assembly. The evacuation system includes a first quick connect fitting configured to mate with a quick connect valve of a vehicle. The refill system includes a second quick connect fitting configure to mate with the quick connect valve of the vehicle. The robotic assembly is couplable to the evacuation system and the refill system, and is configured to autonomously connect the first and second quick connection fittings to the quick connect valve of the vehicle.

The method includes: determining fuel amount to be filled according to the information of vehicle status and the driving route of the vehicle; assigning a fueling device which conforms to a preset position rule to the vehicle according to the current position of the vehicle and the preset position rule; sending a feedback message carrying position information of the fueling device to the vehicle, so that the vehicle drives to the fueling device indicated by a position of the fueling device; and sending information of the fuel amount to be filled and the information of the identifier of the vehicle to the fueling device so that the fueling device offers fuel to the vehicle indicated by the identifier of the vehicle according to the information of the fuel amount to be filled.

A system and apparatus for autonomously fueling a surface water vessel such as an unmanned surface vehicles (USV). A fueling system is secured to the dockside of a land secured or waterborne fueling station. The fueling system has a hose reel, a hose pusher and mooring whip for extending the hose out of the water for access to the surface water vessel. The vessel is equipped with an actuated arm that pivots between a closed position and an open position to capture the hose and connect the nozzle of the hose to the fuel tank of the vessel. The fuel tank has an interface with a mounting plate, nozzle interface and electromagnets that pull, positively locate, and hold the nozzle into the nozzle interface to access the fuel tank and to fuel the vessel.
