Description
Technical Field
The present disclosure relates to a method for operating a hydrogen fuel cell system in a vehicle.
Background
A hydrogen fuel cell system according to the present disclosure includes a plurality of hydrogen fuel cells. Each of these fuel cells may include a fuel cell stack and a controller. A fuel cell stack is an electrochemical cell capable of converting chemical energy from hydrogen fuel and oxygen into electricity. The electricity may for example be used to drive an electric motor.
The hydrogen fuel cell stack is therefore different from a conventional battery. The fuel cell operates on the basis of the fuel (i.e. in the form of hydrogen) supplied to the fuel cell. In a battery, electricity is generated based on chemicals already present in the battery.
The present disclosure relates to the concept of operating a hydrogen fuel cell system with at least one battery in a vehicle. Whenever the vehicle requires electrical power, for example due to the fact that the accelerator pedal is activated, the electrical power may originate from the hydrogen fuel cell system and/or from the at least one battery.
One of the disadvantages of a system in which both the hydrogen fuel cell system and the at least one battery are operated in a vehicle is related to the service life of the battery and/or the service life of the hydrogen fuel cell system.
Disclosure of Invention
It is an object of the present disclosure to provide a method for operating a hydrogen fuel cell system in a vehicle.
The present disclosure provides in a first aspect a method for operating a hydrogen fuel cell system in a vehicle, wherein the vehicle comprises a vehicle control unit VCU for controlling power provided to a driveline of the vehicle originating from any one of a battery management system BMS comprising at least one battery and the hydrogen fuel cell system comprising a plurality of hydrogen fuel cells, wherein the hydrogen fuel cell system further comprises a fuel cell control unit FCCU and a direct current DC to DC converter.
The method comprises the following steps:
receiving, by the FCCU from the VCU, an indication of a state of charge of the at least one battery;
determining, by the FCCU, a demand for power to be provided by the plurality of hydrogen fuel cells based on the indication of the state of charge of the at least one battery and based on an amount of power instantaneously requested;
requesting, by the FCCU, the demand for power to be provided by the plurality of hydrogen fuel cells from the DC-to-DC converter;
Requesting, by the DC-to-DC converter from the FCCU, an amount of current to be provided by the plurality of hydrogen fuel cells;
supplying, by the FCCU, the requested amount of current from the plurality of hydrogen fuel cells to the DC-to-DC converter.
The inventors have found that the VCU cannot be controlled when the amount of power to be supplied by the hydrogen fuel cell system is required. The VCU is typically a function that is physically separate from the FCCC. The VCU may not know the characteristics of the plurality of hydrogen fuel cells. That is, the VCU may not know how to efficiently pressurize the hydrogen fuel cell.
Thus, the inventors have found a method for the FCCU to take charge. The FCCU may determine how much to pressurize the plurality of hydrogen fuel cells based on the state of charge of the at least one battery. The FCCU may have a deep knowledge of the plurality of hydrogen fuel cells that the FCCU can use to determine how much the hydrogen fuel cells can be pressurized.
According to the present disclosure, an indication of the state of charge of at least one battery may be considered as information about how full the at least one battery is actually. Such information may be used by the FCCU to determine how much power may be consumed from the at least one battery. The inventors have noted that the useful life of a battery may be related to the state of charge maintained by the battery. Thus, for example, it may be advantageous to not completely drain the battery, since completely draining the battery may be detrimental to the service life of the battery.
In accordance with the foregoing, the FCCU determines a demand for power to be provided by the plurality of hydrogen fuel cells based on the indication of the state of charge of the at least one battery and based on the amount of power instantaneously requested. Here, the FCCU may consider an electric power ramp favorable to the service life of the hydrogen fuel cell, and may consider an electric power ramp favorable to the service life of the at least one storage battery.
More specifically, the FCCU may follow a preferred power ramp profile for drawing power from the plurality of hydrogen fuel cells, and the VCU may be entrusted with drawing the remaining power from the at least one battery, i.e., insufficient power as the difference between the amount of instantaneously requested power and the power ramp profile.
According to the above, the DC-to-DC converter will request the amount of current to be provided by the plurality of hydrogen fuel cells based on the demand for power to be provided by the plurality of hydrogen fuel cells.
Note that according to the present disclosure, the DC-to-DC controller is controlled by the FCCU. For example, the FCCU may send a current request to the DC-to-DC converter over a bus (e.g., CANBUS). The DC-to-DC converter may then send back what amount of current flows through the DC-to-DC converter, for example, many times per second. This information can be used by the FCCU to control multiple fuel cells so that the current can be maintained. As noted above, one of the advantages of this is that the FCCU controls the amount of power to be provided by the plurality of hydrogen fuel cells.
The present application thus relates to the concept that the FCCU determines the amount of electrical power to be provided by the plurality of hydrogen fuel cells based on the state of charge of the at least one battery, or the like.
Another advantage of the present disclosure is that the FCCU is physically separated from the VCU. The FCCU is responsible for controlling the fuel cell. The VCU is responsible for controlling the vehicle. The two blocks operate independently of each other. This has the advantage that: the FCCU can ensure that the fuel cell is safely shut down even when the VCU is shut down, or when the VCU experiences some error or the VCU experiences an error. Since the FCCU and VCU are physically and operationally separate, the FCCU can ensure that the fuel cell is safely controlled.
The above is true, for example, for the case where there is a collision with the corresponding vehicle, a leak occurs in the fuel cell, the sensor starts to malfunction, and the like.
It is further noted that the DC-to-DC converter may be located between the plurality of hydrogen fuel cells and the vehicle (e.g., at least one battery).
According to the present disclosure, the DC-to-DC converter may include a DC-to-DC converter controller responsible for controlling the operation of the DC-to-DC converter. The DC-to-DC converter controller may, for example, receive a demand for power and may send a demand for an amount of current, as explained in this disclosure.
According to the present disclosure, the instantaneously requested power may be defined as the total amount of power requested by the vehicle (more specifically, by the driver of the vehicle). The instantaneously requested electric power may be based on, for example, a pneumatic pedal of the vehicle, i.e., a throttle. The instantaneously requested power may be communicated to the FCCU in several ways.
According to the present disclosure, the method includes the step of receiving, by the FCCU from the VCU, an indication of a state of charge of the at least one battery. This can be achieved in various ways. For example, the state of charge of the at least one battery may be calculated by the battery management system BMS and may be sent to the VCU via a bus (e.g. CANBUS). The VCU may then communicate the state of charge to the FCCU via a bus (e.g., CANBUS).
In an example, the determining step includes:
determining, by the FCCU, a demand for power to be provided by the plurality of hydrogen fuel cells such that an expected state of charge of the at least one battery does not fall below a predetermined threshold based on the indication of the state of charge of the at least one battery and based on the instantaneously requested amount of power.
An advantage of this particular example is that the service life of the at least one accumulator is guaranteed.
In further examples, the predetermined threshold is between 30% -55%, preferably between 45% -55%, more preferably about 50%.
In an example, the method further comprises the steps of:
receiving, by the FCCU, fuel cell information from the plurality of hydrogen fuel cells, the fuel cell information comprising any of:
a voltage of each of the plurality of hydrogen fuel cells;
a voltage of the plurality of hydrogen fuel cells as a whole;
a relative voltage of the weakest cell compared to an average voltage of each of the plurality of hydrogen fuel cells;
wherein the determining step comprises:
determining, by the FCCU, the demand for power to be provided by the plurality of hydrogen fuel cells based further on the fuel cell information.
An advantage of this particular example is that the FCCU is able to thus handle multiple fuel cells based on information that may directly affect the service life.
In further examples, the FCCU comprises an electrical increase curve and an electrical decrease curve for indicating a preferred ramp up curve for increasing the power from the plurality of fuel cells and a preferred ramp down curve for decreasing the power from the plurality of fuel cells, respectively, and wherein the determining step comprises:
Determining, by the FCCU, the demand for power to be provided by the plurality of hydrogen fuel cells based further on any of the electrical increase curve and the electrical decrease curve.
Preferably, the FCCU controls the amount of power to be provided by the plurality of hydrogen fuel cells such that the actual delivered power over time corresponds to an electrical growth curve. This ensures that the service life of the plurality of fuel cells is improved.
In a second aspect, a hydrogen fuel cell system for operation in a vehicle is provided, wherein the vehicle comprises a vehicle control unit VCU for controlling power provided to a drive train of the vehicle originating from any one of a battery management system BMS comprising at least one battery and the hydrogen fuel cell system comprising a plurality of hydrogen fuel cells, wherein the hydrogen fuel cell system further comprises a fuel cell control unit FCCU and a direct current DC to DC converter.
The FCCU further comprises:
a receiving device configured to receive an indication of a state of charge of the at least one battery from the VCU;
a processing device configured to determine a demand for power to be provided by the plurality of hydrogen fuel cells based on the indication of the state of charge of the at least one battery and based on an amount of power instantaneously requested;

a demand device configured to demand an amount of electrical current to be provided by the plurality of hydrogen fuel cells from the FCCU;

Note that the advantages and definitions disclosed with respect to the example of the first aspect of the present disclosure (which is a method for operating a hydrogen fuel cell system in a vehicle) also correspond to the example of the second aspect of the present disclosure (which is a hydrogen fuel cell system for operating in a vehicle).
In an example, the processing device is further configured to determine a demand for power to be provided by the plurality of hydrogen fuel cells such that an expected state of charge of the at least one battery does not fall below a predetermined threshold, in dependence on the indication of the state of charge of the at least one battery and on the amount of power instantaneously requested.
In a further example, the predetermined threshold is 50%.
In another example, the receiving device is further configured to receive fuel cell information from the plurality of hydrogen fuel cells, the fuel cell information including any of:
A voltage of each of the plurality of hydrogen fuel cells;
a voltage of the plurality of hydrogen fuel cells as a whole;
a relative voltage of the weakest cell compared to an average voltage of each of the plurality of hydrogen fuel cells;
and wherein the processing device is further configured to determine the demand for power to be provided by the plurality of hydrogen fuel cells based also on the fuel cell information.
In a further example, the FCCU comprises an electrical increase curve and an electrical decrease curve for indicating a preferred ramp up curve for increasing the power from the plurality of fuel cells and a preferred ramp down curve for decreasing the power from the plurality of fuel cells, respectively, and wherein the processing device is further configured to determine the demand for power to be provided by the plurality of hydrogen fuel cells based also on any of the electrical increase curve and the electrical decrease curve.

In the drawings, like reference numerals designate identical components or components that perform identical or comparable functions or operations.

Detailed Description
Fig. 1 schematically shows a schematic diagram 1 illustrating the cooperation of a battery 3 and a fuel cell system according to the present disclosure.
The drive train of the vehicle is indicated with reference numeral 2. The drive train 2 of the vehicle is a collection of components that deliver electrical power to the drive wheels. This typically excludes engines or motors that generate electrical power. In contrast, a powertrain is considered to include both an engine or an electric motor and a driveline. In this particular scenario, its power originates from either the battery 3 or the hydrogen fuel cell, or a combination thereof.
The power delivery 12 to the drive train 2 is controlled by a vehicle control unit VCU 9. The VCU 9 draws 13 power from the battery 3 or is provided 14 with power originating from a hydrogen fuel cell.
The present disclosure relates to a method for operating a hydrogen fuel cell system in a vehicle. The fuel cell system includes a fuel cell control unit FCCU 7, a direct current DC-to-DC converter 6, and a plurality of hydrogen fuel cells.
The schematic diagram 1 shows a single functional block called a battery 3. Note that the present disclosure may deal with a battery management system BMS including at least one battery. Typically, a plurality of batteries may be provided for storing sufficient energy for driving the vehicle. The battery may be recharged by inductive power during braking of the vehicle.
The method may begin with receiving 11 by the FCCU 7 from the VCU 9 an indication of the state of charge of the battery 3. The inventors have noted that in order to increase the useful life of the battery, the battery should ideally operate in an operating window between 40% -65%.
According to the present disclosure, the FCCU 7 is separate from the VCU 9 and is responsible for distributing the requested power among the hydrogen fuel cell and the battery 3. To this end, the FCCU 7 may receive an indication of the state of charge of the battery 3, as described above.
The FCCU 7 may then determine the demand for power to be provided by the plurality of hydrogen fuel cells based on the received indication of state of charge and based on the amount of power instantaneously requested.
In other words, the FCCU 7 may, for example, determine how much power is to be provided by the plurality of hydrogen fuel cells so that the state of charge of the battery 3 may not fall below a certain threshold. This improves the service life of the plurality of fuel cells.
Next, the FCCU 7 may request 15 from the DC-to-DC converter 6 a demand for power to be provided by a plurality of hydrogen fuel cells. The DC-to-DC converter then requests 16 from the FCCU 7 the amount of current to be provided by the plurality of hydrogen fuel cells, which is ultimately supplied 17 by the FCCU 7 to the DC-to-DC converter 6.
Note that the current demand is denoted by reference numeral 4, the current supply is denoted by reference numeral 8, the state of charge is denoted by reference numeral 10, and the fuel cell is denoted by reference numeral 5.
Fig. 2 schematically shows a schematic diagram 51 illustrating a hydrogen fuel cell system according to the present disclosure.
The hydrogen fuel cell system 51 is configured to operate in a vehicle, wherein the vehicle comprises a vehicle control unit VCU for controlling power provided to a drive train of the vehicle originating from any one of a battery management system BMS comprising at least one battery and the hydrogen fuel cell system comprising a plurality of hydrogen fuel cells, wherein the hydrogen fuel cell system further comprises a fuel cell control unit FCCU and a direct current DC to DC converter.
The FCCU further comprises:
a receiving device 52 configured to receive an indication of a state of charge of the at least one battery from the VCU;
a processing device 53 configured to determine a demand for power to be provided by the plurality of hydrogen fuel cells based on the indication of the state of charge of the at least one battery and based on an instantaneously requested amount of power;
a request device 56 configured to request the demand for the electric power to be provided by the plurality of hydrogen fuel cells from the DC-to-DC converter;
a demand device 54 configured to demand from the FCCU an amount of current to be provided by the plurality of hydrogen fuel cells;
a supply device 55 configured to supply the required amount of current to the DC-to-DC converter.
Other variations to the disclosed examples can be understood and effected by those skilled in the art in practicing the claimed disclosure, from a study of the drawings, the disclosure, and the appended claims. In the claims, the word "comprising" does not exclude other elements or steps, and the indefinite article "a" or "an" does not exclude a plurality. A single processor or other unit may fulfill the functions of several items recited in the claims. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage.
