Method for estimating remaining capacity of hydrogen fuel power supply

Abstract

The application discloses a kind of hydrogen fuel power supply's residual power estimation method.Hydrogen fuel power supply includes the fuel tank of built-in solid hydrogen material, hydrogen fuel power supply is based on the hydrogen production reaction caused by water injection to fuel tank, to hydrogen gas supply power pile power generation, estimation method includes: based on the real-time water injection quantity integration of single fuel tank, calculate the theoretical residual power generation of fuel tank;Theoretical total power generation and theoretical residual power generation of all fuel tanks are summarized to obtain theoretical power generation;Based on the real-time output power integration of power pile, in combination with the loss of monitored electric quantity, calculate actual consumed energy;Theoretical power generation and actual consumed energy are weighted and fused using feasibility coefficient, estimate used power, based on used power to calculate current residual power.The technical scheme of the present application can improve the estimation accuracy of residual power, can predict the future power generation capacity of the remaining fuel in the fuel tank, reduce the problem of inaccurate residual power display, meet the use demand.
