9. A method for providing a CNG time fill system for simultaneously fueling a plurality of natural gas vehicles, comprising:
-
charging a gas storage system such that it is ready for fueling; opening a time fill valve, turning on a compression system and starting to deliver CNG to a manifold time fill system; closing the time fill valve and allowing the compression system to continue to fill the gas storage system; waiting for the manifold time fill system to reach a predetermined steady static pressure; shutting down the compression system and warning a system operator of a potential leak if the manifold pressure fails to achieve the predetermined steady state level within a predetermined continuous period of time; and continuing to deliver CNG to the manifold time fill system until the manifold pressure has reached a target fill pressure if the predetermined steady static pressure has been achieved for the predetermined continuous period of time. - View Dependent Claims (10, 11, 12, 13, 14)
