Abstract

The present disclosure is directed to a method of maintaining pressure within a compressed fuel storage system. The method may include compressing a fuel source with a compressor; directing fuel from the compressor to a first fuel reservoir; determining that the first fuel reservoir has reached a target fill pressure; transiting from the first fuel reservoir to a second fuel reservoir by redirecting the fuel to the second fuel reservoir; and opening a flow limiting valve to limit the rate of pressure change of the compressor to an allowable rate of pressure change when transitioning from the first fuel reservoir to the second fuel reservoir.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of maintaining pressure within a compressed fuel storage system, the method comprising:
 compressing a fuel source with a compressor;   directing fuel from the compressor to a first fuel reservoir;   determining that the first fuel reservoir has reached a target fill pressure;   transiting from the first fuel reservoir to a second fuel reservoir by redirecting the fuel to the second fuel reservoir; and   opening a flow limiting valve to limit the rate of pressure change of the compressor to an allowable rate of pressure change when transitioning from the first fuel reservoir to the second fuel reservoir.   
     
     
         2 . The method of  claim 1 , wherein the allowable rate of pressure change is substantially equal to a maximum pressure change rate of the compressor. 
     
     
         3 . The method of  claim 1 , wherein the first fuel reservoir includes a first pressure and the second fuel reservoir includes a second pressure, and the first pressure does not equal the second pressure. 
     
     
         4 . The method of  claim 3 , wherein the first pressure is greater than the second pressure. 
     
     
         5 . The method of  claim 3 , wherein the first pressure is less than the second pressure. 
     
     
         6 . The method of  claim 1 , further including opening a control valve associated with the second fuel reservoir. 
     
     
         7 . The method of  claim 1 , further including compressing the fuel source with an electrochemical compressor. 
     
     
         8 . The method of  claim 1 , wherein the fuel source includes at least one of hydrogen, natural gas, and propane.
