[0002] Fuel cells, as a kind of clean energy with high chemical reaction conversion rate, high specific power and no pollution, have been widely used in various types of vehicles in recent years. Compared with traditional fuel vehicles and pure electric vehicles, fuel cell vehicles have a wider driving range and no pollution during operation. Hydrogen, as the anode reactant of fuel cells, is provided by hydrogen cylinders to maintain the operation of fuel cell systems during the reaction.

The hydrogen mass flow parameter can be determined by considering the voltage parameter, the power parameter, and the preset conversion rule of the energy supply device, and the hydrogen mass consumption parameter of the energy supply device can be determined according to the hydrogen mass flow parameter and the time accumulation calculation rule. The calculation of the hydrogen mass flow parameter can be realized without installing a flow meter, thereby avoiding the problem of increasing manufacturing cost caused by installing the flow meter. Thus, the hydrogen mass flow parameter and the hydrogen mass consumption parameter can be calculated at low manufacturing cost, thereby providing a calculation basis for subsequent calculation of the hydrogen consumption per 100 kilometers of the energy supply object device.

[0080] As an optional embodiment, in the step of determining the hydrogen mass flow parameter of the target energy supply device per unit time based on the voltage parameter, the power parameter, and a preset conversion rule, the step includes:

[0084] Through the above-mentioned embodiments, the heat demand can be determined through the output power and the low heat value of hydrogen, the rated power generation can be determined through the single cell voltage and a preset conversion coefficient, and finally the hydrogen mass flow parameter of the target energy supply device per unit time can be determined through the heat demand and the rated power generation. The hydrogen mass flow that needs to be provided can be determined by considering the relationship between heat and power, thereby determining the hydrogen mass flow of the target energy supply device per unit time without setting a flow meter.

[0097] By the above embodiment, by time-integrating the driving power for driving the energy supply device, a characteristic parameter is obtained, when the characteristic parameter is positive, it indicates that the energy supply device discharges in this period of time, when the characteristic parameter is negative, it indicates that the energy supply device charges in this period of time, that is, when the energy supply device charges in this period of time, although hydrogen is consumed, the consumed hydrogen is not wasted, but is converted into electrical energy and stored in the energy supply device, and the characteristic parameter at this time represents the charging / discharging electrical energy of the energy supply device, and the conversion efficiency of the target energy supply device can be calculated according to the average efficiency of 50% of the hydrogen fuel cell system, that is, 15KWH can be generated per 1KG of hydrogen, and by the characteristic parameter, the conversion efficiency of the above target energy supply device, and the hydrogen mass consumption parameter, the actual hydrogen mass consumption is obtained, which can fully consider that part of the hydrogen mass consumption is converted into electrical energy, so that the actual hydrogen mass consumption can be more accurately calculated.

[0099] The hydrogen compensation amount is determined according to the characteristic parameter and the conversion efficiency of the target energy supply device;

[0100] The actual hydrogen mass consumption is determined according to the hydrogen mass consumption parameter and the hydrogen compensation amount.

[0101] By the above embodiment, by calculating the ratio of the characteristic parameter to the conversion efficiency of the target energy supply device, the hydrogen compensation amount is obtained, and by calculating the sum of the hydrogen compensation amount and the hydrogen mass consumption parameter, the actual hydrogen mass consumption is obtained. By considering that part of the hydrogen mass consumption is converted into electrical energy rather than wasted, the actual hydrogen mass consumption can be more accurately calculated, which provides a calculation basis for more accurately calculating the hydrogen consumption per 100 kilometers of the hydrogen energy driven vehicle.

[0102] As an optional embodiment, the method comprises:

[0105] The hydrogen consumption per 100 kilometers of the energy supply object device is determined according to the cumulative mileage parameter and the actual hydrogen mass consumption.

[0106] By the above embodiment, the hydrogen consumption per 100 kilometers of the energy supply object device can be more accurately calculated by calculating the ratio of the cumulative mileage parameter of the energy supply object device to the actual hydrogen mass consumption.

[0107] The embodiment of the present application can calculate the hydrogen mass flow parameter of the energy supply device per unit time through the voltage parameter, the power parameter, the low heat value of hydrogen and the preset conversion coefficient, and then calculate the hydrogen mass consumption parameter through the hydrogen mass flow parameter per unit time. The hydrogen mass flow parameter can be determined by considering the voltage parameter, the power parameter of the energy supply device and the preset conversion rule, and the hydrogen mass consumption parameter of the energy supply device can be determined according to the hydrogen mass flow parameter and the time accumulation calculation rule, so that the calculation of the hydrogen mass flow parameter can be realized without installing a flow meter, thereby avoiding the problem of increasing manufacturing cost caused by installing the flow meter, and the hydrogen mass flow parameter and the hydrogen mass consumption parameter can be calculated at low manufacturing cost. At the same time, the hydrogen compensation amount is determined by considering the charging / discharging state of the energy supply device in this period of time, the characteristic parameter is obtained by integrating the driving power parameter of the energy supply device, the hydrogen compensation amount is obtained by calculating the ratio of the characteristic parameter to the conversion efficiency of the target energy supply device, and finally the actual hydrogen consumption mass is obtained by calculating the sum of the hydrogen compensation amount and the hydrogen mass consumption parameter, so that the case that part of the hydrogen mass consumption is converted into electric energy instead of being wasted can be fully considered, thereby the actual hydrogen consumption mass can be more accurately calculated, thereby providing a calculation basis for subsequent calculation of the hydrogen consumption per 100 kilometers of the energy supply object device.

[0108] The following takes a specific implementation scenario as an example to explain the energy supply device hydrogen consumption determination method disclosed in the embodiment of the present application in detail.

[0109] Taking a hydrogen energy driven truck as an example, the truck is provided with a hydrogen fuel cell group and a power battery. During the working process of the hydrogen energy driven vehicle, the output power parameter Fc_Pwr of the hydrogen fuel cell group and the single cell voltage FcCellVolt of the hydrogen fuel cell group are collected from the bus by the VCU. The single cell voltage FcCellVolt is the maximum voltage of the single hydrogen fuel cell. First, the heat demand is calculated according to the low heat value of hydrogen 1.25 kJ / g and the output power parameter Fc_Pwr, and the calculation process is: heat demand = 1.25 x 1000 x Fc_Pwr. Then, the rated power generation is calculated according to the single cell voltage FcCellVolt and the conversion factor of the overall hydrogen fuel cell group efficiency, and the conversion factor is set to 120000, and the calculation process of the rated power generation is: rated power generation = FcCellVolt x 120000. Finally, the hydrogen mass flow parameter H2_Flow per unit time is obtained by calculating the ratio of the heat demand to the rated power generation, and the unit is g / s. The calculation process is as follows:

[0110]

[0111] After the hydrogen mass flow parameter is obtained from the above calculation, the time is integrated to obtain the instantaneous hydrogen consumption mass, and the instantaneous hydrogen consumption mass is accumulated to obtain the hydrogen consumption mass consumption parameter consumed by the hydrogen fuel cell group during the operation time.

[0112] Considering that the power battery may be used as an electrical appliance and a power source during the operation of the hydrogen energy driven truck, the compensation of the battery needs to be considered. The driving power of the power battery is obtained through the controller of the power battery, and the driving power is integrated with respect to time to obtain a characteristic parameter representing the charging / discharging electric energy of the power battery within the integration time, which is in kW·h. When the characteristic parameter is negative, it indicates that the power battery is in a charging state within the integration time, and when the characteristic parameter is positive, it indicates that the power battery is in a discharging state within the integration time. At this time, the average power of the hydrogen fuel cell group is calculated as 50%, i.e. 15 kW·h of electric quantity is generated per 1 KG of hydrogen. The ratio of the characteristic parameter to 15 kW·h is calculated to obtain the hydrogen compensation amount, and the sum of the hydrogen compensation amount and the hydrogen mass consumption parameter is calculated to obtain the actual hydrogen consumption mass. By considering the compensation of the power battery, the actual hydrogen consumption mass can be more accurately calculated. With the actual hydrogen consumption mass, the mileage parameter is obtained by integrating the speed of the hydrogen energy driven truck, and the hydrogen consumption per 100 kilometers can be easily calculated by using the above two parameters.

[0135] By the above embodiment, the heat demand is calculated by the product of the output power and the low heat value of hydrogen, the rated power generation is calculated by the product of the single cell voltage and the preset conversion coefficient, and the hydrogen mass flow parameter of the target energy supply device per unit time is calculated by the ratio of the heat demand to the rated power generation, so that the hydrogen mass flow per unit time of the target energy supply device can be calculated without setting a flow meter.

[0136] As an optional embodiment, the method comprises:

[0137] obtaining a driving power parameter of a driving function device in the energy supply object device, and performing time integral calculation on the driving power parameter to determine a characteristic parameter of the driving function device;

[0138] determining the actual hydrogen mass consumption according to the characteristic parameter, a hydrogen mass consumption parameter and a conversion efficiency of the target energy supply device.

[0139] Optionally, the driving power parameter can be directly obtained or detected by a controller of the driving power supply device.

[0140] According to the above embodiment, by time-integrating the driving power of the driving power supply device, a characteristic parameter is obtained. When the characteristic parameter is positive, it indicates that the driving power supply device is discharging in this period of time. When the characteristic parameter is negative, it indicates that the driving power supply device is charging in this period of time. That is, when the driving power supply device is charging in this period of time, although hydrogen is consumed, the consumed hydrogen is not wasted, but is converted into electrical energy and stored in the driving power supply device. At this time, the characteristic parameter represents the charging / discharging electrical energy of the driving power supply device. The conversion efficiency of the target power supply device is calculated according to the average efficiency of the hydrogen fuel cell system, which is 50%, i.e. 15 KWH can be generated from 1 KG of hydrogen. By obtaining the actual hydrogen consumption mass according to the characteristic parameter, the conversion efficiency of the above target power supply device, and the hydrogen mass consumption parameter, the actual hydrogen consumption mass can be calculated more accurately by taking into account that part of the hydrogen mass consumption is converted into electrical energy.

[0141] As an optional embodiment, in the above step, determining the actual hydrogen consumption mass according to the characteristic parameter, the hydrogen mass consumption parameter, and the conversion efficiency of the target power supply device comprises:

[0142] determining a hydrogen compensation amount according to the characteristic parameter and the conversion efficiency of the target power supply device;

[0143] determining the actual hydrogen consumption mass according to the hydrogen mass consumption parameter and the hydrogen compensation amount.

[0144] According to the above embodiment, by calculating the ratio of the characteristic parameter to the conversion efficiency of the above target power supply device, the hydrogen compensation amount is obtained, and then by calculating the sum of the hydrogen compensation amount and the hydrogen mass consumption parameter, the actual hydrogen consumption mass is obtained. By taking into account that part of the hydrogen mass consumption is converted into electrical energy rather than being wasted, the actual hydrogen consumption mass can be calculated more accurately, thereby providing a calculation basis for more accurately calculating the hydrogen consumption per 100 kilometers of the hydrogen energy driven vehicle.

[0145] As an optional embodiment, the method comprises:

[0146] obtaining a moving speed of the power supply object device and time-integrating the moving speed to determine a mileage parameter;

[0147] determining a cumulative mileage parameter of the power supply object device according to the mileage parameter and a time accumulation calculation rule;

[0148] determining a hydrogen consumption per 100 kilometers parameter of the power supply object device according to the cumulative mileage parameter and the actual hydrogen consumption mass.

[0149] Through the above embodiment, the ratio of the cumulative mileage parameter of the energy supply object device to the actual hydrogen consumption mass can be calculated to obtain more accurate hydrogen consumption per 100 kilometers of the energy supply object device.

[0150] The embodiment of the present application can calculate the hydrogen mass flow parameter of the energy supply device per unit time through the voltage parameter, the power parameter, the low heat value of hydrogen and the preset conversion coefficient, and then calculate the hydrogen mass consumption parameter through the hydrogen mass flow parameter per unit time. The hydrogen mass flow parameter can be determined by considering the voltage parameter, the power parameter of the energy supply device and the preset conversion rule, and the hydrogen mass consumption parameter of the energy supply device can be determined according to the hydrogen mass flow parameter and the time accumulation calculation rule. The calculation of the hydrogen mass flow parameter can be realized without installing a flow meter, thereby avoiding the problem of increased manufacturing cost caused by the installation of the flow meter, so that the hydrogen mass flow parameter and the hydrogen mass consumption parameter can be calculated at low manufacturing cost. At the same time, the hydrogen compensation amount is determined by considering the charging / discharging state of the driving energy supply device in this period of time. The representation parameter is obtained by integrating the driving power parameter of the driving energy supply device, and the hydrogen compensation amount is obtained by calculating the ratio of the representation parameter to the conversion efficiency of the target energy supply device. Finally, the actual hydrogen consumption mass is obtained by calculating the sum of the hydrogen compensation amount and the hydrogen mass consumption parameter. In this way, the case that part of the hydrogen mass consumption is converted into electric energy instead of being wasted can be fully considered, so that the actual hydrogen consumption mass can be more accurately calculated, thereby providing a calculation basis for the subsequent calculation of the hydrogen consumption per 100 kilometers of the energy supply object device.
