Technical Field

The present invention relates to the field of vehicle technologies, and in particular, to a method and an apparatus for calculating hydrogen consumption, a terminal device, and a storage medium.

Background

In a fuel cell hybrid vehicle, the hydrogen consumption in hundred (kilometers) (kg/100km) is an important performance index, and how to accurately calculate and display the hydrogen consumption in hundred (kilometers) of the vehicle in real time is related to the accurate calculation of the whole cruising mileage of the vehicle and the accurate perception of the economic level of the vehicle, so that the phenomenon that a user complains about the inaccurate display of the hydrogen consumption is avoided.

Compared with the traditional fuel vehicle, the fuel liquid level is directly measured to judge the residual fuel amount and the fuel injection amount of the fuel injection nozzle of the engine is controlled to accurately count the real (actual) fuel consumption, and hydrogen cannot directly measure the so-called liquid level to count the residual amount due to the normal-temperature gaseous characteristics of the hydrogen and can only be converted by measuring the pressure and the temperature of the hydrogen in a certain volume. And due to the design limitation of part of the structure, the pressure pinched by the hydrogen cylinder cannot be measured, and only the pressure in a high-pressure pipeline connected with the hydrogen cylinder can be measured. In addition, the hydrogen supply system is not provided with a flow meter or a structure similar to an oil nozzle, so that the accuracy of hydrogen consumption calculation is low and is very difficult.

Therefore, it is desirable to provide a more accurate hydrogen consumption calculation method.

In an embodiment, please refer to fig. 3, which is a schematic flow chart of another hydrogen consumption calculation method provided in the embodiment of the present application. The method as shown in fig. 3 comprises the following implementation steps:

and S301, calculating and obtaining the residual hydrogen mass at the time t and the residual hydrogen mass at the time (t + k) by the hydrogen system controller HMS 101 according to the current hydrogen volume, the current hydrogen temperature and the current hydrogen pressure of the hydrogen fuel cell system at the time t and the time (t + k).

Specifically, the HMS calculates the remaining hydrogen mass at the time t according to the current hydrogen volume, the current hydrogen temperature, and the current hydrogen pressure of the hydrogen fuel cell system at the time t; and calculating the residual hydrogen mass at the (t + k) moment according to the current hydrogen volume, the current hydrogen temperature and the current hydrogen pressure of the hydrogen fuel cell system at the (t + k) moment.

In one embodiment, the specific calculation of the remaining hydrogen mass is as shown in equation (1):

wherein m is the remaining hydrogen mass, V is the current hydrogen volume, P is the current hydrogen pressure, and T is the current hydrogen temperature.

When the real hydrogen consumption at the last moment is calculated to be 0, or t is 0, C_(t+k)＝C₀.
