1. A gaseous fuel station for filling vehicle tanks with fuel, comprising:
a plurality of storage vessels, including a first storage vessel at a first pressure, and a second storage vessel at a second pressure, wherein the first pressure is less than or equal to the second pressure; a plurality of dispensing sub-stations, each dispensing sub-station comprising a dispensing hose, and a control valve; wherein the plurality of dispensing sub-stations includes a first dispensing sub-station that is in controllable fluid communication with each of the first and second storage vessels such that fluid can flow in a first fluid path from each of the first and second storage vessels through the first dispensing sub-station to a vehicle tank, and wherein the dispensing hose, and the control valve of the first dispensing sub-station are in the first fluid flow path; wherein the plurality of dispensing sub-stations further includes a second dispensing sub-station that is in controllable fluid communication with each of the first and second storage vessels such that fluid can flow in a second fluid path from each of the first and second storage vessels through the second dispensing sub-station to a vehicle tank, and wherein the dispensing hose, and the control valve of the second dispensing sub-station are in the second fluid path; and a controller, connected to receive feedback indicative of a filling parameter from each of the first and second dispensing sub-stations and to provide control signals to the control valves of the first and second dispensing sub-station to implement a desired fill scheme. |
