MOBILE FUEL DELIVERY SYSTEM FIELD OF THE INVENTION

[0001] The present invention relates to fuel delivery and in particular to mobile fuel dispensing.

[0002] The invention has been developed primarily for use as a system for delivering and dispensing dangerous goods including flammable liquids such as petrol fuel to motor vehicles and will be described herein with reference to that application. However, it will be appreciated that the invention is not limited to this particular field of use and is also applicable to the delivery of other fuels (including combustible liquids such as diesel fuel) and vehicle consumables including, by way of example, batteries, battery charging, coolant, brake fluid and motor oil.

DISCUSSION OF THE PRIOR ART

[0003] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of the common general knowledge in the field.

[0004] Refuelling a vehicle is an essential routine for the continued operation of any vehicle. However, fuels are hazardous materials with volatile potential if not appropriately handled. Accordingly, motor vehicles are typically refuelled at dedicated service stations which are well equipped to service vehicles and safely account for the hazards of refuelling. These service stations generally include high volume storage tanks and permanent fuel dispensing installations. However, such service stations are geographically dispersed and only accessible during limited time periods. As such it is frequently inconvenient to travel to a service station to refuel a vehicle.

[0005] Bringing fuel to a desired location to fuel a vehicle may appear to alleviate the inconvenience, however, it is not always safe or possible to do so. Due to the hazardous nature of fuels they must be stored and transported appropriately using specialised containers and methods. Various standards and codes detail the required transportation of dangerous goods, flammable liquids and combustible liquids. To ensure safe transport, only approved containers and packages may be used for storing dangerous goods and the codes and standards specify how they may be handled during transport related activities. In particular, direct transfer of dangerous goods, such as petrol, between vehicles in public places is prohibited.

[0006] Broadly considering mobile fuel delivery, other means include fuel delivery trucks with large integrated fuel tanks which utilise integrated pumps to refuel other vehicles or fuel storage tanks. Another example involves a tractor moveable trailer which must be hauled to a selected site to act as a temporary refuelling station for vehicles. Further examples include the ground support equipment (GSE) commercially used for refuelling aircraft and providing aircraft maintenance. Whilst such fuel dispensing systems are movable, they are not truly hand-portable as they cannot be independently removed or transported separately from their motorised transportation means. The above methods are also ill-suited for enclosed or confined areas such as underground carparks where the presence of such a large quantity of fuel would be potentially catastrophic. Additionally, there are substantial risks when fuelling directly from vehicle-to-vehicle, as with conventional fuel trucks or GSE, and it is unsafe to do so in public places.

[0007] As a partial solution to some of the above problems it is known to manually refuel a vehicle using an approved hand-held fuel container such as a jerry can to pour fuel into a desired vehicle. However, safe manually handleable fuel containers such as jerry cans can only hold a limited amount of fuel, often requiring several cans to completely refuel a vehicle. Notwithstanding this, even a single such container when full of fuel can be prohibitively heavy for some users. The transporting of several jerry cans to a vehicle and manually pouring them into the vehicle is thus a cumbersome inconvenient method that risks spillage.

[0008] Accordingly, there remains a need for systems and methods which can safely and conveniently deliver fuel to a desired publicly accessible location for refuelling a vehicle without requiring vehicle to vehicle fuelling or excessive manual handling.

SUMMARY OF THE INVENTION

[0009] It is an object of preferred embodiments of the present invention to overcome or ameliorate one or more of the disadvantages of the prior art, or at least provide a useful alternative.

[0010] It is an object of the invention in one particularly preferred form to provide a mobile fuelling system which can safely and conveniently dispense fuel into a vehicle in a publicly accessible area without requiring onerous manual handling by an operator.

[0011] According to one aspect of the present invention, there is provided a system for transporting and delivering a dangerous good, the system including: a carrier for transporting a dangerous good; a transfer unit for transferring at least a portion of the dangerous good to a transfer zone spaced from the carrier; and a delivery unit for delivering at least some of the dangerous good from the transfer zone to a recipient.

[0012] In some embodiments the carrier is a vehicle, preferably a delivery vehicle. In some embodiments, the recipient is a vehicle, preferably a target (passenger) vehicle.

[0013] In some embodiments, the dangerous good is a flammable liquid such as, for example, a flammable fuel (e.g. petrol).

[0014] According to another aspect of the present invention, there is provided a mobile fuel delivery system, including: a carrier vehicle having a storage area; one or more fuel containers removably mountable within the storage area; and a transfer unit for transferring one or more of the fuel containers from the carrier vehicle to a fuelling zone, whereby the transferred fuel containers can be used to deliver fuel to a target vehicle located within the fuelling zone.

[0015] According to another aspect of the invention there is provided a mobile fuel delivery system, including: a carrier vehicle having removeable fuel storage; and a portable fuelling assembly releasably stowable in or on the carrier vehicle; wherein, the fuelling assembly is engageable with the removeable fuel storage for fuelling a separate vehicle other than the carrier vehicle.

[0016] In some embodiments, the system includes a plurality of carrier vehicles. In some embodiments the or each carrier vehicle has a fuel storage. In some embodiments the or each carrier vehicle includes a fuelling assembly.

[0017] Preferably, the carrier vehicle is a road-going vehicle. In other embodiments, the carrier vehicle may be an aircraft such as, for example, an aeroplane, helicopter, drone or the like. For certain applications, a drone may be particularly advantageous as a vehicle that can provide greater flexibility in terms of its range of movement, whereby it can readily navigate and access tighter or congested locations with relative ease. In some embodiments, the carrier vehicle is configured to be controlled and driven manually by a user seated within or on the vehicle. In certain embodiments, the carrier vehicle may be configured for movement under an autonomous or semi-autonomous control system, whereby the carrier vehicle can be operated in an unmanned state. In some embodiments, the carrier vehicle may be adapted to be driven by remote (wireless) control.

[0018] In some embodiments, the carrier vehicle is a motor vehicle such as, for example, a car, truck, utility vehicle, van or the like. In other embodiments the carrier vehicle is a trailer, which is adapted to be towed by a primary vehicle (e.g. prime mover). In some embodiments the carrier vehicle is a light utility vehicle. In some embodiments the carrier vehicle is an all terrain vehicle. In some embodiments the carrier vehicle is a motorcycle. In one particularly preferred embodiment the carrier vehicle is a light utility vehicle having a storage area such as, for example, a (rear) storage tray.

[0019] Preferably, one or more fuel containers (e.g. jerry cans) are removably mountable within the storage area. Each fuel container is preferably sized to hold a predetermined volume of fuel. In some embodiments, each fuel container is sized to hold a predetermined volume of fuel sufficient to fill a fuel tank of a road going vehicle, preferably a passenger vehicle. In other embodiments, each fuel container is sized to hold a predetermined volume of fuel which is less than the volume required to fill a fuel tank of a road going vehicle, preferably a passenger vehicle. In some embodiments, each fuel container is configured to hold a volume of fuel within the range of around 20% to 60%, preferably around 25% to 50%, more preferably around 25% to 35% of the capacity of the fuel tank of a passenger vehicle. It has been found that fuel containers configured to hold a volume of fuel of less than 40%, more preferably less than 35% and most preferably around 25% or less of the capacity of the fuel tank of a passenger vehicle are particularly advantageous for manual handling of discrete fuel containers.

[0020] Such embodiments in which the capacity of the fuel container is less than the capacity of the fuel tank of a road going vehicle are particularly advantageous because the relatively lower weight and size of these fuel containers renders them easier to handle manually by a single user. In addition, fuel containers of this size can be readily filled and refilled via a petrol bowser at common, publicly accessible service stations. Furthermore, such limited volume fuel containers also present a reduced risk of spilling hazards and fires, with the maximum spill necessarily limited to the volume of the respective container (e.g. 20 litres).

[0021] As is described in detail below, a plurality of discrete fuel container with a capacity less than the capacity of the fuel tank of a vehicle to be filled by the fuel container can be advantageously fluidly connected in series to provide a sufficient supply of fuel to fill or refill the fuel tank of the target vehicle.

[0022] Preferably, the carrier vehicle is adapted to carry a predetermined maximum volume of fuel. In some embodiments, the carrier vehicle is adapted to carry up to 1000 litres of fuel. In some embodiments the carrier vehicle is adapted to carry a volume of fuel within the range of between 20 and 1000 litres. In some embodiments, the carrier vehicle is adapted to carry the predetermined volume of fuel within a single fuel container. Advantageously, however, the carrier vehicle is preferably adapted to carry the predetermined volume of fuel within two or more discrete fuel containers. In certain embodiments, each fuel container is configured to hold approximately 25% of the capacity of a fuel tank of a target vehicle, wherein the number of discrete fuel containers that can be carried by the carrier vehicle is a multiple of four. In one preferred embodiment the carrier vehicle is configured to carry 960 litres of fuel in 48 discrete fuel containers in the form of, for example, 20 litre jerry cans.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0096] Referring to the drawings, preferred embodiments of the invention are directed to a mobile fuel delivery system to deliver fuels to vehicles outside of a specialised service station environment, and systems and methods to safely and conveniently refuel a vehicle in a public place.

[0100] In some embodiments the mobile fuel delivery system includes a carrier vehicle having removeable fuel storage. A portable fuelling assembly is stowable in the carrier vehicle; wherein the fuelling assembly is engageable with the removeable fuel storage for fuelling a separate vehicle in a public place. In some embodiments the fuelling assembly includes a fuel holding module; a pumping module; and an electrical module and is preferably stowable in the carrier vehicle. In some embodiments the fuel is a fluid fuel. In preferred embodiments the fuel is a liquid fuel. In certain more preferred embodiments, the fuel is selected from the group of fuels including petrol, diesel, or ethanol.

[0101] Whilst preferred embodiments of the invention are directed to liquid fuel delivery, systems and methods of the present invention are also applicable to alternative ancillary services such as, for example, mobile electric vehicle charging, fuel additives; wiper blade replacement; mobile interior and exterior car cleaning; ATO Compliant Digital Log and expense book products and other digital products; windscreen or other glass replacement, and other motor vehicle aftermarket products.

[0102] The system is configured to dispense fuel from removeable fuel containers using a portable fuelling assembly. The fuel and fuelling assembly are carried by a carrier vehicle. The mobile system incorporates fuel storage, pumps, meters, and ancillary equipment to enable the safe and efficient delivery of fuel to recipient vehicles in convenient and accessible locations.

[0103] Referring to Figure 1, there is illustrated a mobile fuel delivery system including a carrier vehicle 110 having removeable fuel storage including a plurality of fuel containers 112 and a portable fuelling trolley assembly 114.

The storage tray also includes a storage recess 118 for receiving the trolley assembly. The storage tray further includes a storage enclosure 120 for housing the contents of the storage tray.

[0106] The storage tray 116 is sufficient to carry approximately 960 litres of fuel. In various embodiments the carrier vehicle carries up to 1000 litres of fuel. In some embodiments the carrier vehicle carriers between 20 and 1000 litres of fuel.

[0107] As even low capacity tankers are not permitted to transfer dangerous good directly to another vehicle, the present invention provides removable fuel storage on the carrier vehicle as an alternative solution for transporting the fuel. By transporting the fuel in removable packages, they may be subsequently transferred to a fuelling assembly for fuelling a vehicle sperate from the carrier vehicle.

[0108] In order to safely transport fuel, the fuel must be stored in an appropriate container which is hydrocarbon capable and can safely sustain impacts and pressure during transit. Additionally, to be portable the fuel container should be sufficiently lightweight to facilitate relatively easy manual handling, even when full.

[0109] Custom designed fuel tanks similar to racing fuel tanks require approval from regulatory offices which would be prohibitively expensive when using small quantities of such custom tanks. Approved, standard 200L drums such as intermediate bulk carriers are too large and heavy to manoeuvre without specialised handling equipment. Such large drums are difficult to remove from the carrier vehicle to dispense fuel into a recipient vehicle. Furthermore, these drums cannot be safely filled using conventional service station equipment and instead need a specialised filling facility.

[0110] Smaller approved containers with capacities in the realm of 20L are suitable for manual handling and can be filled at a service station using already installed geographically diverse filling infrastructure, removing the need to have specialised, dedicated filling facilities.

[0111] These smaller 20L containers, relative to larger containers present a much lower risk profile for spillage and fire, in that the maximum size of any single spill is limited to 20L, and hence the pool size of a resulting fire is limited in diameter and available quantity of fuel for the fire. Approved 20L containers include the standard 20L drum and 20L jerry cans. The 20L drum, having a circular cross section, does not allow for the most efficient packing of multiple containers and the circular shape makes for awkward manual handling. The 20L jerry can's rectangular shape provides for efficient packing in an array for transport. Jerry cans are also designed for ease of manual handling with integral handles and quick action caps.

[0112] Thus, the inventors of the present invention identified jerry cans as particularly advantageous fuel storage containers applicable to the portable fuelling assembly 114. The fuel storage accordingly includes a plurality of fuel containers 112 in the form of, for example, forty-eight pressed steel 20L jerry cans.

[0113] The fuel storage may contain a first group of fuel containers for containing a first fuel and a second group of fuel containers for containing a second fuel. Various fuels may be stored in various combinations of the fuel containers. For example, out of 48 fuel containers: 24 fuel containers may contain diesel; 12 fuel containers may contain 91 octane petrol; and 12 fuel containers may contain 98 octane petrol. Any desired combination of fuels may be contained in the fuel containers wherein the fuel is at least one of petrol, diesel, ethanol, or any other desired fluid fuel.

[0114] As best shown in Figure 2, the plurality of discrete fuel containers 112 are arranged in an array of longitudinal rows 210. Fuel containers in each longitudinal row are spaced by lateral guide rails 212 extending to a loading edge 214 of the storage tray 116 for guiding the placement of fuel containers during loading and unloading. Referring to Figure 3 the guide rails 212 terminate at a predetermined loading height 310 of the loading edge.

[0115] As best shown in Figures 5 and 6, a lifting device 510 is provided in the storage recess 118 of the carrier vehicle 110 to assist an operator when loading or unloading the fuelling assembly 114 onto or off the carrier vehicle. In the illustrated embodiment, the lifting device includes a platform 512 and a winch 514 for lifting the portable fuelling trolley 114 into the storage recess. The platform is lifted into the storage recess by the winch up lifting rails 516 mounted to the inside of the recess. The lifting device 510 and the fuelling assembly are matched and balanced to eliminate the need for set up for each load and unload operation.

[0116] Referring to Figure 7, the unloaded fuelling assembly 114 may be manoeuvred to the side of the carrier vehicle 110 and abutted against the loading edge 214 of the storage tray 116. Fuel containers 112 are then drawn along the guide rails 212 and onto the fuelling assembly at the predetermined loading height.

[0117] Once the fuel containers are loaded onto the fuelling assembly, they are interconnected in fluid communication with the fuelling assembly, as shown in Figure 8. The system is then ready to refuel a recipient vehicle separately from the carrier vehicle.

[0118] Aspects of the fuelling assembly will now be described with reference to Figures 9 to 19. The portable fuelling assembly is preferably a trolley assembly 910 including a fuel holding module 912 for receiving fuel storage, a pumping module 914 for pumping fuel from the fuel storage and an electrical module 916 for powering, monitoring and controlling the pumping module. All modules are mounted to a trolley frame 918 having wheels to manoeuvre the trolley between the carrier vehicle and the recipient vehicle.

[0119] In some embodiments the trolley frame has two pairs of wheels. In some embodiments the trolley frame has treads or sleds in lieu of wheels. In alternative embodiments the fuelling assembly modules are mounted to a static frame.

[0120] In some embodiments the electrical module is demountable from the trolley frame to safely service away from the hazardous fuelling equipment. In some embodiments the electrical module includes a control module for selectively operating pumping modules. In some embodiments the electrical module includes a battery module to power the control and pumping modules. In some embodiments the battery module is demountable from the fuelling assembly for safely charging wherein a charged battery can be swapped in for continuous operation. In some embodiments the control module and the battery module are integrated.

[0121] Preferably the trolley frame 918 is relatively light weight and formed from electrically conductive materials to prevent sparking from static charge build up. In some embodiments the trolley frame is formed from a rigid material. In some embodiments the material is electrically conductive for grounding purposes. In some embodiments the trolley frame is formed from metal. In some embodiments the metal is selected from the group of metals including steel, stainless steel, aluminium and cast iron. In some embodiments the trolley frame is formed from other materials. In some embodiments the trolley frame is a single rigid frame. In some embodiments the trolley frame is at least partially collapsible. In some embodiments the assembly is linearly collapsible. In some embodiments the frame is linearly collapsible along sliding arms. In some embodiments the frame is linearly collapsible along a telescopic member. In some embodiments the assembly is foldable.

[0122] The trolley assembly also includes an earth connecting member 920. In some embodiments the earth connecting member is a flexible earth strap. In some embodiments the earth connecting member is an earthing chain. In some embodiments the earthing chain is a 4.0mm steel chain. Preferably the earth connecting member is of sufficient length to ensure proper earthing contact is made with the ground.

[0123] The trolley assembly further includes a handle 922 for manually manoeuvring the trolley. In other embodiments the trolley assembly is self propelled and may be remote controlled. The trolley assembly also includes a breaking mechanism 924. In some embodiments the breaking mechanism is capable of holding the trolley stationary for an indefinite period without slippage on a 1:4 grade. In some embodiments the breaking mechanism is configured to be actuated by an actuator mounted to the handle of the trolley frame, whereby a user can readily apply the braking mechanism by manual hand operation, as required. Preferably, the braking mechanism is failsafe requiring an operator to actuate an actuator on the handle to release the braking mechanism when moving the trolley.

[0124] The trolley assembly 910 is stowable in the storage recess 118 of the carrier vehicle in a safe condition under flammable atmosphere conditions. The trolley assembly is stowed and transported in a collapsed storage configuration.

[0125] In alternative embodiments the portable fuel assembly is towed by the carrier vehicle. In some embodiments the portable fuel assembly is towed along with the carrier vehicle. In some embodiments the fuelling assembly is carried in the carrier vehicle in discrete parts. In some embodiments the fuelling assembly is a single self-contained assembly within the carrier vehicle.

[0126] In some embodiments the fuelling assembly includes a housing for hoses. In some embodiments the fuelling assembly includes a holster for a fuelling nozzle. In some embodiments the holster is configured to contain dripping from the nozzle. In some embodiments the holster is configured to block operation of the nozzle to prevent leakage during transit. In some embodiments the holster is configured to lock the nozzle in position for safe transportation. In some embodiments the fuelling assembly further includes capacity for a spare fuel container; traffic cones; a fire extinguisher; and a hydrocarbon capable spill kit.

[0127] The fuel holding module 912 includes a fuel holding shelf 926 for receiving fuel containers. In the illustrated embodiment, the shelf is configured to receive individual fuel containers, preferably four 20L jerry cans. In various embodiments various arrangements of fuel containers are held by various means, for example, racks or retaining straps.

[0128] The shelf 926 may include a plurality of holding rails 928 which align with guide rails 212 of the carrier vehicle's fuel storage. In alternative embodiments, the shelf does not include holding rails. A leading edge 930 of the fuel holding shelf 926 is a raised lip for retaining the fuel containers on the shelf. The leading edge 930 of the fuel holding shelf is abutting engageable with the loading edge of the carrier vehicle. In alternative embodiments, the shelf does not include a lip. A retaining strap may be included instead of or in addition to the lip. In alternative embodiments the fuel holding module interlocks with the carrier vehicle for loading and unloading.

[0129] The fuel holding shelf 926 and holding rails 928 are configured to hold the fuel containers, having open necks 932, with each neck aligned with and proximal to each adjacent neck. The necks 932 of each fuel container face outwards from the fuel holding module 912 and towards the leading edge 930.

[0130] Referring to Figure 11, the fuel holding module 912 further includes a plurality of fuelling fittings 1110 each applicable to at least one fuel container 112. The fuelling fittings are preferably syphon fittings having an inlet 1112 at the bottom, an outlet at the top 1114 and a syphon port 1116 intermediate the inlet and outlet. The syphon fitting is sealingly affixed to the open neck 932 of a fuel container 112 by a camlock 1118. Preferably the syphon fitting is constructed using a standard jerry can cap, complete with operating cam, such that it will fit and seal on any jerry can neck and use the same quick operating latch system as the cap attached to that can. This allows the syphon fittings to be applicable to any jerry can. In alternative embodiments the fuelling fitting may be threadingly engaged with the fuel container. In some embodiments the fuelling fitting is otherwise clamped or bolted to the open neck of a fuel container.

[0131] In the embodiment of Figures 12 and 13, the fuel holding module 912 is selectively elevatable between a point above the predetermined loading height 310 and a point below the predetermined loading height. In some embodiments the fuel holding module is elevatable by sliding arms 1210 of the trolley frame 918. In alternative embodiments, the trolley frame and fuel holding module may be entirely rigid so that the fuel holding module is permanently at the fuel loading height of the carrier vehicle tray platform in order to allow jerry cans to be readily slid from one to the other without requiring the adjustment of the fuel holding module height.

[0132] Referring to Figures 14 to 16, the interconnection of fuel containers and the pumping module 914 will now be described. Whilst 20L fuel containers are convenient for storage and manual handling purposes, passenger vehicles have fuel capacities generally between 50L and 80L. Therefore, it is necessary to simultaneously fill from up to 4 containers. If all 4 containers are drawn from simultaneously, the inevitable result at the end is 4 partially full containers. This leads to low volumetric efficiency. The fuelling fittings of the present invention overcome this by sequentially interconnecting fuel containers to empty them sequentially, thereby leaving a combination of empty, partially empty and full containers at the end instead of 4 partially full ones.

[0133] Syphon fuelling fittings 1410, 1412, 1414 and 1416 are respectively affixed to the open neck of four fuel containers 1418, 1420, 1422 and 1424 with the inlet of each fuelling fitting within the respective fuel container. The syphon port 1116 of the first fitting 1410 affixed to the first fuel container 1418 functions as an air inlet during syphoning. The outlet 1114 of the first fuelling fitting 1410 is connected to the syphon port of the fuelling fitting 1412 of a second fuel container 1420 by hose 1426. The outlet of fitting 1412 is then connected to the syphon port of the fuelling fitting 1414 of a third fuel container 1422 by hose 1428. The outlet of fitting 1414 is in turn connected to the syphon port of the fuelling fitting 1416 of a fourth fuel container 1424 by hose 1430. Preferably each fuel container is interconnected with adjacent fuel containers.

[0134] The syphon system operates by using the suction of the pump to draw fuel from the final container which is sealed, except for the syphon feed from the adjacent container. The resultant small drop in pressure in this final container causes fuel to flow into it from the adjacent interconnected container. This process continues in sequence along the chain of containers until the first container, where instead of fuel, air is drawn into the container to replace the outward fuel flow. As each container empties, air is drawn through it back along the chain of containers towards the last container.

[0135] Thus, the configuration of sequentially connected syphon fittings interconnects the fuel containers into a syphon circuit wherein the first fuel container 1418 is substantially emptied before fuel is drawn from the second fuel container when fuelling a vehicle. A similar effect applies regarding the second and third, and third and fourth containers such that each fuel container is substantially emptied before the next container begins to be emptied. This provides an advantage wherein when the fuelling of a vehicle requires multiple fuel containers worth of fuel, each container is fully utilised in series so as not to result in a plurality of disparately, partially empty fuel containers. This reduces fuel waste and substantially reduces handling difficulties when refilling fuel containers thereby making the fuelling system more efficient.

[0136] The pumping module 914 includes at least one pump circuit 1432 having a pump inlet 1434, a pump 1436 and a pump output 1438. In some embodiments a plurality of pump circuits is provided. The pump 1436 is a motorised pump suitable for use in an explosive vapour, hazardous environment.

[0137] At least one fuel container is connected to the pump circuit. In the embodiment of Figure 9 the outlet of the fuelling fitting 1416 of the fourth fuel container 1424 is connected to the pump input 1434 by hose 1440. In some embodiments the pump inlet is a suction connection. In some embodiments the pump output is a dispensing connection. The pump circuit sequentially pumps fuel from the fuel containers through the inlets to the pump output 1438.

[0138] In some embodiments the pumping module includes a fluid volume cut off to prevent air being drawn into the pump circuit via empty fuel containers in the syphon circuit. In some embodiments the fluid volume cut off is between 1 and 20 litres of fuel remaining. In some embodiments the fluid volume cut off is when 75 out of approximately 80 litres of fuel has been pumped.

[0139] The pumping module also includes an output circuit 1440 having a fuelling nozzle 1442 and an output coupling 1444 connected by an output hose 1446. The output coupling 1444 is engageable with the pump output 1438. In alternative embodiments the pump circuit and the output circuit are integral. Preferably the output hose is at least three metres long for convenience of reach and manoeuvrability when fuelling a vehicle.

[0140] In some embodiments the pump circuit 1432 and output circuit 1440 are selectively sealable to retain fluid within the respective circuits. In some embodiments the pump circuit and output circuit are selectively sealable by way of the pump inlet 1434 having a ball valve, the output coupling 1444 being a dry break coupling and the fuelling nozzle 1442 being a locking nozzle. In other embodiments other valves or seals may be used.

[0141] The pump circuit 1432 and output circuit 1440 being selectively sealable enables the pumping module to maintain a unified wet system during transport to ensure substantially no air is pumped through the pumping module when measuring fuel flow. This is important so as not to contaminate the fuel or distort the flow of pumped fuel. When measuring the volume of flow of fuel through the pumping circuit it is critical to ensure only fuel flow is measured and that no air is allowed in the circuit to distort fuel flow measurements. The pumping module may also incorporate an air eliminator and settling tank to further ensure the circuits remain wet.

[0142] In some embodiments the respective hoses interconnecting the fuel containers and the components of the pumping module are permanently attached to the fuel holding module of the fuelling assembly. In some embodiments the connection of each short hose to each fuelling fitting includes a check valve to control leakage.

[0143] The pumping module includes a pumping enclosure. In some embodiments the pumping module is encased in an enclosure. In some embodiments the enclosure is vapour tight. In some embodiments the enclosure includes ventilation slots. In some embodiments the ventilation slots are in the base of the enclosure. In some embodiments a drip tray is provided beneath the enclosure. In some embodiments the trip tray is a sliding trip tray integrated into the base of the enclosure. In some embodiments the enclosure includes resealable removable panels.

[0144] Referring to the illustrated embodiment of Figures 16 and 17 the pumping module may preferentially include a pair of pump circuits 1610 and 1612 each pump circuit being used to pump disparate fuels. In some embodiments the fuels may be petrol and diesel. In other embodiments the fuels may be differing octanes of petrol. Each pump circuit is substantially similar and includes a suction pump input 1614 to connect to fuel storage; a pump 1616; a settling tank 1618; an air eliminator 1620; a flow meter 1622; and a dispensing pump output 1624 engageable with an output coupling 1626 of an output circuit. Both circuits are housed within a vapour tight enclosure 1628 of the pumping module. Vents 1630 are provided in the base of the vapour tight enclosure.

[0145] The pump circuits of Figures 16 and 17 are provided in a cross over configuration to safely and conveniently separate the pump circuits in a space efficient manner. In some embodiments a pump circuit is configured from the top right of the pumping module to the bottom left. In some embodiments a pump circuit is configured from the top left of the pumping module to the bottom right. The cross over of pump circuits also logically separates disparate fuel types by isolating their respective inputs and outputs from each other. A Left to right or Right to Left convention prevents cross contamination of pump circuits.

[0146] Referring to Figure 18 a loaded and interconnected fuelling assembly according to one particularly preferred embodiment invention includes fuel storage interconnected with a pumping circuit and electrical controls for monitoring and controlling the fuelling assembly.

[0147] The fuel storage includes four fuel containers 1810 which are sequentially interconnected by hoses affixed with quick connect couplings, preferably camlocks 1812. The cascade sequence of interconnected fuel containers forms a syphon circuit. The fuel containers are connected to the pumping module 1814 via an input check valve 1816 on one end of a hose and a ball valve 1818 on the other. The ball valve 1818 selectively allows fuel to be pumped from the fuel containers 1810 by a pump 1820.

[0148] The pump 1820 is an electrical motorised pump powered by a battery 1822. In other embodiments the pumping system is manually powered. In some embodiments the pumping system is powered by a hand crank. The pump 1820 outputs to a settling tank 1824 connected to an air eliminator 1826. In some embodiments the air eliminator includes a -free floating lever air vent formation within a sealed body to provide positive venting of air under pressure.

[0149] The air eliminator 1826 loops back to the fuel storage in parallel with a flash arrestor 1828. The pump circuit from the settling tank 1824 through an output check valve 1830 and a flow meter 1832 to an output coupling 1834 that couples a fuelling nozzle 1836 to the pump circuit via a dry break or similar coupling. The fuelling nozzle 1836 is preferably a National Measurement Institute (NMI) approved lockable nozzle, with a safety cut-off, suitable for gasoline, petrol, ethanol fuel oil and biodiesel. In other embodiments the fuelling nozzle is defined by a selectively sealable opening at the distal end of an output hose.

[0150] The flow meter 1832 measures flow through the pump circuit and outputs flow measurement data to a register 1838. The register 1838 is powered by the battery 1822 stores flow data including flow measurement data. In some alternative embodiments the flow meter and register are integral. Additionally, the register is connected to an access device 1840 for outputting and displaying data as well as for configuring control of the pump circuit.

[0151] In some embodiments a fuel tank 1842 or intermediate bulk carrier may also be connected to the pumping module 1814 via a tank ball valve 1844 and tank coupling 1846. The pumping module may then separately pump from the sequential fuel containers 1810 or the fuel tank 1842. Alternatively, the pumping module may draw from both the fuel tank and the fuel containers.

[0152] In various embodiments various components of the assembly illustrated in Figure 18 may be integrally formed, directly connected or connected via various alternative hoses, valves and couplings. For example, the hoses may be flexible hoses, rigid pipes or any suitable medium for fluid communication. The camlocks and couplings may be any alternative quick coupling or suitable connection for fluid communication between components.

[0153] With reference to Figure 19 the electrical module for measurement and control of a pumping module having a pair of pump circuits will be described in detail, however, it will be appreciated that the configuration could also be applicable to one pump circuit or to more than a pair of pump circuits with respective omissions and additions.

[0154] A pair of pump control circuits 1910 and 1912 each have respective pumps 1914 and 1916, respective flow meters 1918 and 1920 and respective registers 1922 and 1924. The pumps and registers are connected to nodes of an isolator switch 1926. The isolator switch may selectively connect a battery 1915 to the either the first pump control circuit 1910, the second pump control circuit 1912 or to neither circuit. The battery 1915 is preferably a 12-volt lithium ion deep cycle or similar battery of sufficient capacity and duty cycle to adequately power the circuit.

[0155] Additionally, the first register 1922 controls a first pump switch 1928 between the first pump 1914 and the isolator switch 1926. The second register 1916 similar controls a second pump switch 1930 between the second pump 1916 and the isolator switch. The isolator switch and pump switches are used to alternate between the pump circuits. Relays may be used to provide some or all of the switching functions described in this electrical section

[0156] A keyed or twist release or similar function emergency stop control 1932 allows the battery to be safely and securely disconnected from the entire circuit during an emergency. A battery monitor 1934 may measure the voltage and temperature of the battery.

[0157] Data lines from each of the flow meters connect to respective registers. Both registers 1922 and 1924 connect to an access device 1936. In some embodiments the access device is a tablet device. In some embodiments the access device is a computer. In some embodiments the access device is an input/output port applicable to an external device.

[0158] The flow meters 1918 and 1920 are NMI pattern approved flow meters which transmit flow measurement data pulses to their respective registers. In some embodiments the flow meter is analogue. In some embodiments the flow meter is digital. In some embodiments the flow meter includes an integral display. Flow measurement data including total delivery volume is transmitted to the access device where it is stored and may be matched with identification and billing information of a customer.

[0159] A method of delivery fuel will now be described in detail with reference to Figure 20 wherein the method at least includes the following steps or parts thereof.

[0160] Step 2010: A carrier vehicle is used to deliver fuel in removeable fuel containers as well as a portable fuelling system to a desired location, in response to a customer initiated order or request signal (e.g. entered via a user's handheld electronic device and sent to a central control system). The carrier vehicle may travel freely along public roads and in enclosed spaces such as underground parking centres.

[0161] Step 2012: Upon arriving at the location of a vehicle for refuelling, the carrier vehicle is parked and the portable fuelling assembly unstowed from the storage recess of the carrier vehicle using a lifting device to lower the fuelling assembly. The fuelling assembly is unpacked from its storage configuration. The fuelling assembly is manoeuvred adjacent the carrier vehicle and a leading edge of the fuel holding shelf abuttingly engaged with the carrier vehicle at the loading height wherein guiderails of the carrier vehicle's fuel storage align with the fuelling assembly's holding shelf.

[0162] Step 2014: Fuel containers can then be removed from the carrier vehicle and loaded onto the fuelling assembly, preferably by sliding the fuel containers along the rails of the carrier vehicle across their respective abuttingly engaged edges. The fuel containers can then be transported by the fuelling assembly to a fuelling area away from the carrier vehicle.

[0163] Step 2016: The loaded fuel containers on the fuelling assembly are first interconnected in fluid communication with each other in a sequential syphon circuit using fuelling fittings. The fuelling fittings are preferably syphon fittings having an inlet; outlet at oppositely directed ends and a syphon port intermediate the inlet and outlet. The interconnected fuel containers of the syphon circuit are then connected to the suction pump input of a pump circuit of the pumping module of the fuelling assembly. A dispensing output hose, of suitable length, with a fuelling nozzle at its distal end is connected to the dispensing output of the pump circuit.

[0164] Step 2018: The loaded and interconnected fuelling assembly is manoeuvred to the vehicle for fuelling and the fuelling nozzle inserted into a fuel intake of the vehicle. The pump of the fuelling circuit is operated to pump fuel out from the fuel containers and through a flow meter in order to dispense fuel from the fuelling nozzle into the vehicle. The fuelling assembly sequentially empties the fuel containers one after the other starting furthest from the pump until the vehicle has been fuelled to the desired amount. A control module of the fuelling assembly can be programmed to operate the pumping module until a predetermined quantity of fuel is dispensed. Alternatively, a trigger of the fuelling nozzle may be manually operated until a desired quantity of fuel is dispensed. Under either mode a flow meter will measure fuel flow and output flow data to a register. Additionally, the fuelling assembly is configured with safety cut-offs and fluid volume cut offs.

[0165] Measured flow data of the volume of fuel dispensed to the vehicle can then be used, along with the daily retail price of fuel to produce a tax invoice containing full details of the fuel delivery. This delivery tax invoice may be associated with a customer account and emailed immediately to the customer.

[0166] Step 2020: The dispensing output hose is disconnected from the pump circuit and sealed so as to retain fuel in the output hose. The pump output and pump input of the pump circuit are also sealed so as to retain fuel in the pump circuit. Retention of fuel in the output hose and pump circuit ensure a unified wet system when storing and transporting the fuelling assembly. A unified wet system is important as the flow meter must only detect fuel flow, and not air flow, for accurate measurement and billing of fuel volume. The fuelling fittings and interconnecting hoses of the fuel containers are also disconnected for storage and safe transport. The fuelling fittings may be stored in an appropriate fitting magazine to prevent spillage and protect the fittings. The nozzle may be housed in an appropriate holster.

[0167] Step 2022: The fuelling assembly is manoeuvred adjacent the carrier vehicle and a leading edge of the fuel holding shelf abuttingly engaged with the carrier vehicle wherein guiderails of the carrier vehicle's fuel storage align with the fuelling assembly's holding shelf. Fuel containers can then be unloaded from the fuelling assembly into the carrier vehicle by sliding the fuel containers along the rails of the carrier vehicle.

[0168] Step 2024: With the pumping module disconnected and the fuel containers unloaded, the fuelling assembly can then be collapsed, if necessary, into a storage configuration and a lifting device used to lift the fuelling assembly into the storage recess of the carrier vehicle to thereby stow the fuelling assembly in the carrier vehicle. The fuelling assembly may be transported with pumping module and electrical module including batteries mounted to the fuelling assembly. Fuelling fittings and hoses may be stored in appropriate sections of the storage recess or otherwise in the carrier vehicle.

[0169] Returning to step 2010 the carrier vehicle can once again deliver fuel to a desired location demonstrating the dispatchability of the present invention. The illustrated method for delivering fuel may be repeated until the fuel containers require refilling. Wherein appropriate fuel containers are used, for example 20 litre jerry cans, the carrier vehicle can refill its fuel storage at any standard fuel service station and then continue to deliver fuel via public roads to any desired location.

[0170] It will be appreciated that the illustrated systems and methods can safely and conveniently deliver fuel to a desired publicly accessible location for refuelling a vehicle without requiring vehicle-to-vehicle fuelling or excessive manual handling.

[0171] Although the invention has been described with reference to specifics example, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
