Pressure or flow regulation method for gaseous hydrogen dispensing system

A system for adding a pressurized gas to a receptacle container that is fluidically connected thereto, the system comprising:

• a) a plurality of banks of pressurized gas containers, the banks each having a plurality of pressurized gas containers, wherein each pressurized container of a bank is fluidically connected to a common bank manifold and a common bank pressure control valve (PCV);
• b) the common bank PCV being configured to be downstream from that bank, and all pressurized gas containers thereof, the common bank PCV adapted to control a flow of the pressurized gas from that bank to the receptacle container;
• c) the bank PCVs configured and adapted to operate in sequence in response to a computer control;
• d) the computer control configured and specifically programed to control the opening and closing of the bank PCVs in response to a pressure value representing a pressure of the pressurized gas in a first pressurized container of a first bank (Bank A), the computer control specifically programmed to execute the steps of:
• (A) detecting a first pressure in a first pressurized gas container of the first bank (Bank A),
• (B) comparing the first pressure of the first pressurized gas container of the first bank (Bank A) to a receptacle container pressure,
• (C) when the comparison of (B) reaches a pre-determined minimum pressure differential, comparing a pressure value for each pressurized gas containers of a second bank (Bank B) to identify a second pressurized gas container having the smallest pressure differential with the receptacle pressure container,
• (D) opening a second isolation valve of the second pressurized gas container of the second bank to create a fluid communication between the second pressurized gas container and the second bank PCV,
• (E) proportionally opening the second bank PCV to maintain a minimum pressure of the gas flow to the receptacle container based on a pressure decay of a pressurized gas flow through the first bank PCV, and
• (F) when the first pressure of the first pressurized gas container falls to a second preset pressure differential with the pressure of the receptacle container, closing the first PCV.
