In the embodiment, the fuel cell can only output power by a fixed value according to different working conditions, energy loss can be caused by the fixed value of the output power, and when the fuel cell runs at a certain power, the running power of the fuel cell is not matched with the required power, so that the problem of battery overcharge of the battery can occur in the charging process, and when the SOC of the battery cannot meet the requirement of the power, the fuel cell can output energy loss at a high power.
In view of the above problems, a fuel cell vehicle energy control method according to an embodiment of the first aspect of the invention is described below with reference to fig. 2 to 3.
As shown in fig. 2, the fuel cell vehicle energy control method of the embodiment of the invention includes at least step S1, step S2, and step S3.
And step S1, acquiring the required power of the whole vehicle, and acquiring the SOC value of the power battery.
In the embodiment, when the vehicle is in a non-braking state, the required power of the whole vehicle is acquired in real time according to different running conditions of the vehicle, wherein the running conditions of the vehicle such as an idling condition or an accelerating condition and the like, and the SOC value of the power battery is acquired in real time through a battery management system. The SOC value of the power battery is mainly used for reflecting the residual capacity of the power battery.
And step S2, determining the power threshold range of the fuel cell where the required power of the whole vehicle is located.
In the embodiment, the fuel cell power threshold value may be divided into the fuel cell output power, for example, denoted pfc, the fuel cell minimum stable operating power, for example, denoted Pfcmin, the power corresponding to the fuel cell peak efficiency point, for example, denoted pfcop, the fuel cell rated power, for example, denoted Pfcrate, the fuel cell peak power Pfcmax, and the like, the relationship between the vehicle demand power and the fuel cell power threshold value is determined after the vehicle demand power is acquired, and the step S3 is executed when it is determined that the vehicle demand power is within the fuel cell power threshold value range.
And step S3, controlling the output power of the fuel cell and the power battery according to the threshold range of the power of the fuel cell and the SOC value where the required power of the whole vehicle is located.
In the embodiment, when the vehicle is in different working conditions, the required power of the whole vehicle is usually different, when the threshold range of the power of the fuel cell in which the required power of the whole vehicle is located is determined, the SOC value of the power battery is determined, and the output powers of the fuel cell and the power battery in different threshold ranges are controlled by detecting the change of the required power of the whole vehicle and the SOC threshold range in which the SOC value of the power battery is located, so that the energy loss of the fuel due to constant value output under different working conditions is avoided.
According to the fuel cell vehicle energy control method, the required power of the whole vehicle and the SOC value of the power cell are obtained, when the threshold range of the power of the fuel cell where the required power of the whole vehicle is located is determined, the output power of the fuel cell and the output power of the power cell are controlled according to the threshold range of the required power of the whole vehicle and the SOC value of the power cell, namely the output power of the fuel cell under different working conditions is regulated and controlled in real time according to the power change of the required power of the whole vehicle and the change of the SOC value of the power cell.
In some embodiments, controlling the output power of the fuel cell and the power cell according to the threshold range of the power of the fuel cell and the SOC value where the required power of the entire vehicle is located includes determining that the required power of the entire vehicle is greater than zero and less than the minimum stable operating power value of the fuel cell, that is, the required power of the entire vehicle is smaller; when the SOC value of the power battery is smaller than a first SOC threshold value, controlling the fuel battery to output a minimum stable working power value, and controlling the power battery to charge at a first charging power, wherein the first charging power is a difference value between the minimum stable power value of the fuel battery and the required power of the whole vehicle; when the SOC value of the power battery is greater than or equal to the first SOC threshold and smaller than the second SOC threshold, the fuel battery system is started, the fuel battery is controlled to output the minimum stable working power value, the power battery is controlled to be charged with the first charging power, or the fuel battery system is stopped, and the power battery is controlled to output the required power of the whole vehicle; when the SOC value of the power battery is larger than or equal to the second SOC threshold value, the power battery is controlled to output the required power value of the whole vehicle, namely when the required power of the whole vehicle is small, the power battery provides all required power at the moment in order to prevent the battery from being overcharged.
In the embodiment, the vehicle power demand is denoted as pdem, for example, and when it is determined that pdem is less than zero, the vehicle is in a braking state.
For example, the vehicle required power pdem is compared with the minimum stable operating power value Pfcmin of the fuel cell, when it is determined that 0< pdem < Pfcmin, the vehicle is in a non-braking state, the SOC value of the power cell is continuously determined, when the SOC value of the power cell is smaller than a first SOC threshold value, for example, the SOC value of the power cell is less than 40%, the control device controls the fuel cell to output the minimum stable operating power value Pfcmin, and when the fuel cell operates at a low power, the power cell is controlled to be charged at a first charging power, which is a difference between the minimum stable power value Pfcmin and the vehicle required power pdem, so that the situation that the charging power is too large, the battery is overcharged, and the charging safety is protected.
For example, when the SOC value of the power battery is less than or equal to 40% and less than or equal to 70%, the control device controls the fuel battery to output the minimum stable working power value Pfcmin and controls the power battery to be in a charging state, or controls the fuel battery system to be closed, namely the fuel battery keeps an original state, the power battery discharges and provides the required power of the whole vehicle, namely the output power of the fuel battery is determined according to the actual power requirement of the fuel battery, and the energy loss caused by the maximum power output is avoided.
For example, when the SOC value of the power battery is larger than or equal to 70%, the output power of the fuel battery is zero, and the control device controls the power battery to discharge so as to provide the required power of the whole vehicle and prevent the battery from being overcharged.
The problem of battery overcharge when the required power of the whole vehicle is low is avoided by determining the threshold range of the fuel cell where the required power pdem of the whole vehicle is located, namely controlling the output power of the power battery and the fuel cell according to the threshold range where the power battery is located under the condition that the required power pdem of the whole vehicle is smaller than the minimum stable working power value Pfcmin of the fuel cell.
In some embodiments, the obtained vehicle required power pdem is compared with a power value Pfcmax corresponding to the peak efficiency point of the fuel cell and a minimum stable operating power value Pfcmin, when it is determined that the vehicle required power pdem is greater than the minimum stable operating power value and less than a power value corresponding to the peak efficiency point of the fuel cell, for example, Pfcmin < pdem < pfcop, the vehicle is in a non-braking state, the SOC value of the power cell is continuously determined, when the SOC value of the power cell is less than a first SOC threshold value, for example, the SOC value of the power cell is less than 40%, the control device controls the fuel cell to output a power value pfcop corresponding to the peak efficiency point of the fuel cell, and controls the power cell to be charged with a second charging power, which is a difference between the power value pfcop corresponding to the peak efficiency point of the fuel cell and the vehicle required power, and the vehicle required power value pfcop is charged with the second charging power, that is, the second charging power can be expressed as pfcop-pdem, and when the SOC of the power battery is small and cannot meet the power follow-up requirement, the power output of the fuel battery can be controlled according to the actual power requirement.
When the SOC value of the power battery is greater than or equal to the first SOC threshold and smaller than the third SOC threshold, for example, 40% < the SOC value of the power battery < 50%, the fuel cell system is closed, namely the fuel cell keeps the original state, the power battery is controlled to discharge and output the required power of the whole vehicle, or the fuel cell system is started, the fuel cell is controlled to output a power value pfcop corresponding to the peak efficiency point of the fuel cell, the power cell is in a charging state, the power cell is controlled to be charged with the second charging power, and the opening and closing of the fuel cell system and the output power of the power cell are regulated in real time according to the threshold range where the SOC value of the power cell is located, so that the energy loss is reduced.
When the SOC value of the power battery is equal to or greater than the third SOC threshold value and equal to or less than the fourth SOC threshold value, for example, 50% < the SOC value of the power battery < 60%, the fuel cell and the power battery are controlled accordingly by determining whether the output power pfc of the fuel cell is zero, that is, when the output power pfc of the fuel cell is equal to 0, the fuel cell system is controlled to be turned off, that is, the fuel cell is kept in an original state, and the power battery is controlled to discharge and output the power required for the entire vehicle, or, when the output power pfc of the fuel cell is equal to 0, the fuel cell system is controlled to be turned on, that is, the output power of the fuel cell is pdem, the power is kept unchanged, and the output power of the power battery is zero, and the power required for the entire vehicle is controlled, that is, the output powers of the fuel cell and the power battery are controlled accordingly by determining whether.
When the SOC value of the power battery is greater than the fourth SOC threshold value and less than the second SOC threshold value, for example, 60% < the SOC value of the battery < 70%, the output powers of the fuel battery and the power battery are controlled accordingly by determining whether the output power pfc of the fuel battery is zero, that is, when the output power pfc of the fuel battery is equal to 0, the fuel battery system is controlled to be turned off, that is, the fuel battery is kept in an original state, and the power battery is controlled to discharge and output the required power for the entire vehicle, or, when the output power pfc of the fuel battery is equal to 0, the fuel battery system is controlled to be turned on, the fuel battery is controlled to output the minimum stable operating power value Pfcmin, and the power battery is controlled to discharge and output the first discharge power, thereby reducing energy. The first discharging power is the difference value between the required power of the whole vehicle and the minimum stable working power value, namely the first discharging power is pdem-Pfcmin.
When the SOC value of the power battery is larger than the second SOC threshold value, for example, the SOC value of the power battery is larger than or equal to 70%, the fuel battery keeps the original state, the power battery is controlled to discharge to output the required power of the whole vehicle, the power battery is controlled to discharge according to different conditions, and energy loss can be reduced.
In some embodiments, when the vehicle is in a non-braking state, it is determined that the vehicle required power pdem is greater than the power value Pfcrate corresponding to the peak efficiency point of the fuel cell and less than the rated power Pfcrate of the fuel cell, that is, pfcop < pdem < Pfcrate, the relation between the power cell SOC value and the SOC threshold value is continuously compared.
When the SOC value of the power battery is smaller than a first SOC threshold value, namely the SOC value of the power battery is less than 40%, obtaining first output power according to the rated power Pcrete of the fuel battery, the required power pdem of the whole vehicle and the output power pbat of the power battery, controlling the fuel battery to output the first output power, controlling the power battery to be in a charging state, and charging by using third charging power, wherein the third charging power is the difference value between the rated power of the fuel battery and the required power of the whole vehicle, namely the third charging power is Pcrete-pdem, and the third charging power is used for charging the power battery, so that overcharging of the battery can be avoided, and charging safety is ensured.
When the SOC value of the power battery is greater than the first SOC threshold and less than the second SOC threshold, for example, 40% < the SOC value of the power battery < 70%, the fuel battery is controlled to output the required power pdem of the whole vehicle, the power of the power battery is kept unchanged, the output power is zero, and the SOC value of the power battery is controlled according to different threshold ranges in response to the output powers of the fuel battery and the power battery, so that the energy loss can be reduced.
When the SOC value of the power battery is greater than or equal to the second SOC threshold, for example, the SOC value of the power battery is greater than or equal to 70%, a second output power value is obtained according to the power value pfcop, the vehicle demand power pdem, and the power battery output power pbat corresponding to the peak efficiency point of the fuel battery, the fuel battery is controlled to output the second output power, and the power battery is controlled to be charged with a fourth charging power, where the fourth charging power is a difference between the vehicle demand power and the power value corresponding to the peak efficiency point of the fuel battery, that is, the fourth charging power is pdem-pfcop, and the fourth charging power is used as the power battery, so as to prevent the battery from being overcharged.
In some embodiments, the first output power is equal to min { Pfcrate, Pdem + k1 · Pbat }, and the first output power is a smaller power therebetween as shown by the formula, where Pfcrate is a rated power of the fuel cell, Pdem is a demanded power of the whole vehicle, Pbat is a charging power of the power cell, and k1 is a charging proportionality coefficient, and by increasing the charging proportionality coefficient k1, the output power of the fuel cell can be regulated in real time under a specific working condition and output at a proper power, so that energy loss is reduced.
In some embodiments, the second output power is equal to max { Pfcop, Pdem-k2 · Pbat }, and the second output power is a larger power therebetween, where Pfcop is a power value corresponding to a peak efficiency point of the fuel cell, Pdem is a required power of the entire vehicle, Pbat is an output power of the power cell, and k2 is a discharge proportionality coefficient, and by increasing the discharge proportionality coefficient k2, the output power of the fuel cell can be regulated in real time under a specific working condition and output at a proper power, so that energy loss is reduced.
In some embodiments, it is determined that the power demanded of the entire vehicle is greater than the rated power of the fuel cell and less than the peak power of the fuel cell, for example, Pfcrate < pdem < Pfcmax, and when the vehicle is in a non-braking state, the relationship between the SOC value of the power cell and the SOC threshold value is continuously determined, as described in the following embodiments.
