Abstract
A kind of real-time predicting method of hydrogen cell automobile remaining mileage, by detecting the gas pressure intensity P and gas temperature T in hydrogen storage bottle, with reference to hydrogen storage bottle capacity V, calculates the remaining hydrogen mass M 1 in hydrogen storage bottle；The current hydrogen consumption speed m of fuel cell car is detected, according to t=(M1 M0)/m, calculates and is persistently travelled to hydrogen storage bottle hydrogen quality lower limit M0 time t with present speed u；The remaining mileage S of automobile is predicted finally according to S=ut.The real-time predicting method of the hydrogen fuel cell remaining mileage of the present invention is simple and convenient, the mileage that existing driving model can be kept to hydrogen cell automobile can also travel carries out the Accurate Prediction of real-time online, fuel cell car is avoided to occur the operational reliability for improving hydrogen cell automobile because of the situation that hydrogen exhausts and casts anchor on the way.
Description
Technical field
The invention belongs to fuel cell car technical field, and in particular to a kind of reality of hydrogen cell automobile remaining mileage
When Forecasting Methodology.
Background technology
With the development and the improvement of people's living standards of social economy, national car ownership is in rapid increase trend.
The a large amount of of automobile are used while people's go off daily is facilitated, and also greatly exacerbate fossil energy crisis, environmental pollution
The problems such as.For the sustainable development of human society, the cleaning power vehicle that taps a new source of energy is imperative.
Hydrogen cell automobile is converted the chemical energy in hydrogen by fuel cell using renewable resource hydrogen as the energy
For electric energy, discharge product is water, is truly realized the target of " zero-emission, pollution-free ", has broad application prospects.Due to combustion
The limitation of hydrogen amount of storage in battery car is expected, in real time the accurate remaining mileage for understanding hydrogen cell automobile, for avoiding hydrogen from firing
The operational reliability that hydrogen cell automobile is improved due to the phenomenon that hydrogen exhausts and casts anchor on the way, tool are occurred for material battery car
It is significant.But existing hydrogen cell automobile field still lacks the side of effectively prediction hydrogen cell automobile remaining mileage
Method.
The content of the invention
Still lack in effectively prediction hydrogen cell automobile residue to solve hydrogen cell automobile field in the prior art
A kind of method of journey, it is possible that the defect for the phenomenon that hydrogen exhausts and cast anchor on the way, the present invention provides hydrogen fuel cell vapour
The real-time predicting method of car remaining mileage.
A kind of real-time predicting method of hydrogen cell automobile remaining mileage, comprises the following steps：
1), during the traveling of hydrogen cell automobile, gas pressure intensity P and gas temperature on detection car in hydrogen storage bottle
T, with reference to known hydrogen storage bottle capacity V, the molal weight M of hydrogenH2And ideal gas constant R, according to formula M1=PVMH2/ RT,
Calculate remaining hydrogen quality M in hydrogen storage bottle1；
2) lower limit of hydrogen quality in hydrogen storage bottle is set as M0, according to formula M=M1-M0Calculate using hydrogen matter
Measure M；Supply of the hydrogen from hydrogen storage bottle into fuel cell drives typically by the pressure differential between hydrogen storage bottle and airway tube, maintains
The delivery rate m of hydrogen needs the Hydrogen Vapor Pressure in hydrogen storage bottle to maintain more than certain numerical value, i.e. remaining hydrogen in hydrogen storage bottle
There is lower limit M0 in quality, lower limit M0 setting is relevant with the delivery rate m of hydrogen, it is preferred that hydrogen quality in hydrogen storage bottle
Lower limit M0It is set as the 10% of hydrogen storage bottle hydrogen nominal-mass Mmax；
3), the detection current hydrogen consumption speed m of fuel cell car, calculates and consumes hydrogen to terminating with the speed
Time t=M/m；
4), the current travel speed u of detection fuel cell car, remaining mileage S is calculated according to formula S=ut.
The present invention operation principle be：
Chemical energy in hydrogen is converted into electric energy by hydrogen cell automobile using hydrogen as the energy by fuel cell, then
Mechanical energy is converted electrical energy into by motor, and then drives automobile to advance.The traveling process of hydrogen cell automobile is correspondence
The discharge process of hydrogen fuel cell, the travel speed u of hydrogen cell automobile also correspond to hydrogen consumption speed m.Due to hydrogen
While there is relation t=S/u with remaining mileage S, therefore S=ut can be passed through in remaining time t (=M/m) of the gas under wear rate m
=Mu/m predicts the remaining mileage of hydrogen cell automobile.
Beneficial effect：The present invention is by gas pressure intensity and temperature in vehicle-mounted hydrogen storage bottle, fuel cell hydrogen wear rate,
The detection of the parameters such as fuel cell car travel speed, carries out real-time estimate, effectively to the remaining mileage of hydrogen cell automobile
Hydrogen cell automobile is avoided to occur due to the phenomenon that hydrogen exhausts and casts anchor on the way so that the operation of hydrogen cell automobile can
Greatly enhanced by property.
Brief description of the drawings
Fig. 1 is a kind of flow chart of the Forecasting Methodology of hydrogen cell automobile remaining mileage in the embodiment of the present invention.
