Development of Real-time Pressure Loss Compensation Method for Hydrogen Refueling Station to Increase Refueling Amounts

Abstract

A new real-time pressure loss compensation method was developed for hydrogen refueling stations to increase fuel cell vehicle driving ranges. Pressure loss coefficient measurement every refueling enabled to distinguish the conditions of each vehicle and the station. A time-lag pressure loss measuring method was utilized to accurately get the pressure loss without the vehicle’s data. The vehicle tank pressure was accurately estimated only from the station’s measurement data. As a result, the vehicle’s SOC was enhanced by an average of 4.6%
