1. A system for filling a portable gas cylinder with a preselected quantity of fluid for supplying energy needs to a user, the system comprising a reservoir for supplying a volume of fluid, a compartment for receiving the gas cylinder, and a supply line extending between the reservoir and the compartment for delivering the pressurized fluid to the gas cylinder, characterized in that: the compartment is enclosed and has a door that is accessible by a user only before and after a filling operation to load and unload the gas cylinder;a retractable coupler is connected to the supply line, the coupler being located in the compartment and being automatically movable toward a fill valve on the gas cylinder during the filling operation to thereby connect with the fill valve and deliver a quantity of fluid under pressure to the gas cylinder from the reservoir;a control panel having a user interface for selecting a quantity of pressurized fluid to be delivered to the gas cylinder;a first sensor positioned for detecting when the preselected quantity of fluid has been delivered to the gas cylinder; anda processor operably associated with the control panel, the first sensor and the retractable coupler for automatically stopping the filling operation and moving the coupler way from the fill valve when the first sensor detects that the preselected quantity of fluid has been delivered to the gas cylinder. 2. A system for filling a portable gas cylinder according to claim 1, characterized in that the door includes a locking mechanism operable by the processor for automatically locking the door in a closed position during the filling operation and unlocking the door after the filling operation. 3. A system for filling a portable gas cylinder according to claim 1, characterized in that the first sensor determines one of a pressure limit and a weight limit for the gas cylinder. 4. A system for filling a portable gas cylinder according to claim 3, characterized in that the processor is operable to stop the filling operation before delivery of the preselected quantity of fluid is completed when the first sensor detects that the limit of the gas cylinder has been reached. 5. A system for filling a portable gas cylinder according to claim 4, characterized in that the first sensor determines at least one of a weight limit and volume limit for the gas cylinder. 6. A system for filling a portable gas cylinder according to claim 5, characterized in that a second sensor is provided for determining a pressure limit of the gas cylinder. 7. A system for filling a portable gas cylinder according to claim 6, characterized in that the processor is operable to stop the filling operation before delivery of the preselected quantity of fluid is completed when at least one of the first and second sensors detects that at least one of the weight limit, volume limit, and pressure limit of the gas cylinder has been reached. 8. A system for filling a portable gas cylinder according to claim 6, characterized in that the second sensor is located in the retractable coupler. 9. A system for filling a portable gas cylinder according to claim 1, characterized in that a cradle is located in the compartment for receiving the gas cylinder so that the fill valve on the gas cylinder is in alignment with the retractable coupler. 10. A system for filling a portable gas cylinder according to claim 9, characterized in that the first sensor comprises a load cell located beneath the cradle for sensing the weight of the gas cylinder. 11. A system for filling a portable gas cylinder according to claim 1, characterized in that a further sensor is provided for determining a correct connection between the retractable coupler and the fill valve on the gas cylinder, the processor being operable to cancel the fill operation and retract the coupler when an incorrect connection has occurred. 12. A system for filling a portable gas cylinder according to claim 1, characterized in that a display is coupled to the processor for indicating a selected quantity of fluid to be delivered to the gas cylinder and for indicating completion of the filling operation. 13. A system for filling a portable gas cylinder according claim 1, characterized in that a fluid dosing device is operably associated with the reservoir for transferring the fluid from the reservoir to the gas cylinder. 14. A system for filling a portable gas cylinder according to claim 13, characterized in that the fluid dosing device comprises a hollow body, a piston located in the hollow body for reciprocal movement with respect thereto, an input fluidly connected to the reservoir, and an output fluidly connected to the supply line, such that movement of the piston in one direction causes fluid to enter the hollow body through the input from the reservoir, and movement of the piston in the opposite direction causes fluid to flow through the output and into the supply line. 15. A system for filling a portable gas cylinder according to claim 14, characterized in that the dosing device further comprises a temperature sensor associated with the hollow body and a position sensor associated with the piston, the temperature and position sensors being in communication with the processor to thereby calculate and control movement of the piston to deliver the preselected quantity of fluid based on a change in volume of the fluid due to a change in temperature. 16. A system for filling a portable gas cylinder according to claim 1, characterized in that the gas cylinder comprises electronic information relating to a valid use date and further comprising a reader to detect the use date, the processor being operably associated with the reader to determine a valid or expired status of the gas cylinder. 17. A system for filling a portable gas cylinder according to claim 1, characterized in that the compartment is mounted on a stationary support. 18. A system for filling a portable gas cylinder according to claim 1, characterized in that the reservoir and compartment are mounted on a motorized vehicle for transporting the system to different locations. 19. A system for filling a portable gas cylinder according to claim 17, characterized in that a plurality of compartments are provided, each compartment having a separate and independently operable door, retractable coupler, control panel, and first sensor operably connected to at least one controller. 20. A method of filling a portable gas cylinder that uses the system of claim 1, characterized in that it comprises the following steps: positioning a gas cylinder in the compartment;locking the compartment door in a closed position to prevent access by a user;programming a preselected quantity of fluid to be transferred from the reservoir to the gas cylinder;moving the retractable coupler toward the fill valve on the gas cylinder to thereby connect the coupler to the fill valve;determining that a proper connection has occurred between the coupler and the fill valve;directing fluid from the reservoir to the gas cylinder through the supply line;stopping the flow of fluid from the reservoir when it has been determined that the predetermined quantity of fluid has been transferred;retracting the coupler from the fill valve; andunlocking the compartment door to allow access by a user to remove the gas cylinder from the compartment. 21. A method of filling a portable gas cylinder according to claim 20, characterized in that the filling operation is stopped and the compartment door is unlocked before the predetermined quantity of fluid has been transferred to the gas cylinder when at least one of the following conditions has occurred: 1) a pressure limit of the gas cylinder has been reached; 2) a weight limit of the gas cylinder has been reached; and 3) an incorrect connection between the retractable coupler and the fill valve has occurred. 22. A method of filling a portable gas cylinder according to claim 20, characterized in that it further comprises the steps of detecting a valid use date of the gas cylinder prior to connecting the coupler to the fill valve, and unlocking the compartment door to permit a user to remove the gas cylinder without transferring fluid to the gas cylinder.
