Description

Simulating Control Method for Plug-in Fuel Cell Vehicle

The present invention relates to a simulation control method for a plug-in fuel cell vehicle, and more particularly, to control the supply of energy from a primary power source and a secondary power source in a plug-in fuel cell vehicle (PFCV). A simulation method for a fuel cell vehicle.

Vehicles powered by engines powered by gasoline, diesel, etc. are the most common types of vehicles.However, in engines using fossil fuels, new sources of energy may be due to various causes such as reduced oil reserves and environmental pollution. There is a growing need. Various technologies are being studied as alternative energy sources for vehicles, and technologies that are close to the most practical stages of use include those related to electric vehicles using batteries as energy sources or fuel cell vehicles driven using fuel cells as energy sources. In addition, while the main power source is an engine using fossil fuel as an energy source, research into a hybrid vehicle using a rechargeable battery or a fuel cell as an auxiliary power source is also actively conducted. In addition, in the battery, the conventional car battery is further charged to use the rotation of the wheel when driving the car, and the battery can be supplied with electricity from an external power source so that the battery can be charged by inserting a charging plug to the outside of the vehicle. There is also a technology for plug-in cars.

However, fuel cell vehicles have the advantages of high energy efficiency, no emission of environmental pollutants, and short charging time, while low power density, long start-up time, It is disadvantageous in terms of cost and durability, and has a disadvantage of requiring the construction of a hydrogen source infrastructure. In addition, electric vehicles have the advantages of high power density, no environmental pollutant emissions, and (relatively) advantageous in terms of cost and durability, while long charging times, low energy efficiency and heavy battery weight It has the disadvantage of lowering fuel economy.

In the past, there has been a great deal of research on engines (using fossil fuels) / motors (using electricity from batteries or fuel cells) hybrid cars, and nowadays these types of cars are already put into production. However, such an engine / motor hybrid vehicle has an advantage of reducing the consumption of fossil fuels compared with the conventional ones, but in fact, the fossil fuel consumption is not different from the conventional ones. It only delays the adverse effects of reduced fossil fuel reserves, environmental pollution, etc., and cannot overcome them.

As described above, because the conventional engine / motor hybrid vehicle cannot overcome the problems of the vehicle using the conventional fossil fuel as an energy source, research on a new type of energy source is still ongoing. .

As part of this research, there is a technology for hybrid vehicles using plug-in batteries and fuel cells as primary / secondary power sources, respectively. Such a vehicle is called a plug-in fuel cell vehicle (hereinafter referred to as PFCV). At the beginning of 2007, Ford and GM announced the concept of PFCV at motor shows, etc., and compared with conventional engine / motor hybrid cars, it can completely solve the environmental pollution problem, and can also solve the problem of conventional fuel cell vehicles and Compared with the conventional electric vehicle (using a battery or plug-in), the above-mentioned advantages of the two vehicles can be combined, and research and development on PFCV is actively made now.

And a motor connected to the secondary power source, the primary power source, and the secondary power source to receive electric power and drive the electric power to the motor and the gear. At this time, the motor adjusts the amount of power supplied from the primary power source and the secondary power source according to the driving state or the state of each power source. (I.e., in the motor, for example, in some conditions, only the primary power source or the secondary power source is used, and in some conditions, the primary power source and the secondary power source are used together.)

As described above, the PFCV not only obtains the advantages of the fuel cell vehicle and the electric vehicle, but also significantly reduces the capacity of the fuel cell stack compared to the conventional fuel cell vehicle, thereby significantly reducing the cost and running costs. In addition, the durability and cold startability is improved, and the driving distance can be greatly increased. Accordingly, the practical use of PFCV is expected in the near future. At this time, the most necessary for the practical use of the PFCV is the optimization of the operation algorithm in the motor, many studies have been made.

Hereinafter, a simulation control method for a plug-in fuel cell vehicle according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

2 is a flowchart of a control method of the present invention. The plug-in fuel cell vehicle simulation control method of the present invention uses a battery as a primary power source and a fuel cell as a secondary power source to control a power source obtained from a fuel cell and a battery according to a driving condition, thereby driving a motor and a gear. By simulating the control of the fuel cell vehicle, it is implemented in the form of a simulator, which is software installed on a storage medium, which is executed by arithmetic processing means including a computer. That is, the present invention is to prevent the waste of the cost by consuming the fuel cell and the battery every time the experiment when performing the experiment in the actual driving conditions with the actual PFCV, implement a simulation device of the PFCV in the computer The simulation is performed by inputting the driving conditions as numerical values so that the results for various driving conditions can be obtained without performing experiments with the actual PFCV. That is, the driving information may be stored in advance in the form of a database or the like in the storage medium in which the simulator is installed, or may be used by the simulator after the experimenter inputs and stores a desired value when performing the simulation. have.

The control method of the present invention consists of an initial setting step and a cyclic step as shown in FIG.

The initial setting step may include a1) setting a fuel cell stack and a battery capacity (S01); a2) step S02 of setting a battery state of charge (SOC) value to 1; a3) step S03, in which the value of i is set to 1; It is made, including. In the initial setting phase, the size of the fuel cell stack and the battery capacity can be set as desired by the experimenter, and the results for various fuel cell stacks and the battery capacity can be obtained. Where i is a variable value for the loop operation and is an integer greater than or equal to 0 and has no physical meaning.

The number of cycles can be determined by the experimenter. This value is an integer equal to or greater than 1 and can be entered as desired by the experimenter. Initially, it is assumed that the battery is fully charged, and now enters the cycle shown in FIG. 2 to perform the simulation. The cyclic step may include: b1) checking whether the i value is N (S04); b2) when the i value is not N, driving information stored on the storage medium is read (S05); b3) sequentially calculating vehicle load power S06-AC motor power S07-DC / AC inverter input power S08 using the driving information; b4) a step of performing power distribution control to adjust the power obtained from the fuel cell and the battery by using the driving information and the calculated values obtained in the steps b2) and b3) (S9); b5) DC / DC converter output power (S10)-fuel cell power and calories (S11)-battery capacity and SOC (S12)-hydrogen and air input (S13)-air compressor power (S14)-water pump power (S15) The auxiliary power S16 is sequentially calculated; b6) calculating the system efficiency (S17); b7) adding 1 to the i value and returning to step b1) (S18); It is made, including.

In other words, while continuously adding 1 to the i value, the cycle is repeated until N is reached, and various values are calculated to calculate a result. As described above, the driving information may be stored in advance in the form of a database or the like in the storage medium in which the simulator is installed, or used by the simulator after inputting and storing a desired value when the experimenter performs a simulation. It can be considered as a possible value, that is, a known value in advance.

Here, in step b4), a substantial power distribution control is performed. This will be described in more detail below.

3 is a flowchart of a method for controlling power distribution according to the present invention, and the step b4) (that is, step S09 in FIG. 2) will be described in more detail.

First, when the index value is 0, the driving is performed by the battery only. When the index value is 1, the driving is performed by using the fuel cell and the battery together, but the battery is being charged, and the index value is 2 Is a state in which the fuel cell and the battery are used together to drive the battery SOC, but the battery SOC is maintained. The index value is set to 0 (T01). Here, as the cyclic step shown in FIG. 2 is performed by increasing the value of i by 1, the power distribution control step of FIG. 3 is also performed every time the value of i increases by 1, thereby updating the battery SOC. do. Accordingly, even if the index value is initially set to 0, the index value is also changed as the battery SOC changes during the cyclic step.

The power distribution control method shown in FIG. 3 ultimately, at various times, when the battery SOC value gradually decreases over time while driving the PFCV with the battery in a fully charged state under various driving conditions. It is intended to obtain a result such as whether it is optimal to obtain power from the fuel cell to perform driving, and how much power is optimal to obtain from the fuel cell at this time. The control method will now be described in detail below.

Since the flow of FIG. 3 is rather complicated, the flow chart of FIG. 3 divides the flow into the leftmost column, the flow to the middle row, and the flow to the rightmost column.

First, the leftmost column flow represents a control step at the end of the circulation step. In this case, the power distribution control may include p1) checking whether the i value is N (T02); p2) when the i value is N (T02-yes), the power value P _fc obtained from the fuel cell is set to 0, and the power value P _bat obtained from the battery is set to the driving power value P _d (T03); p3) checking whether the battery SOC is smaller than the SOC reference range minimum value SOC _min (T04); p4) when SOC <SOC _min in step p3) (T04-no), updating the battery SOC value (T05); It is made, including.

Here, the power value P _fc obtained from the fuel cell is set to 0, and the power value P _bat obtained from the battery is set to the driving power value P _d , that the motor and the gear are driven only by the battery and the fuel cell is not used. Indicates.

Next, the flow up to the middle row represents a control step at the time when the circulation step is being cycled (T02-no) or when the battery SOC is below the reference range (T04-yes). In this case, the power distribution control may include q1) determining whether the i value is N (T02); q2) when the i value is N (T02-yes), the power value P _fc obtained from the fuel cell is set to 0, and the power value P _bat obtained from the battery is set to the driving power value P _d (T03); q3) checking whether the battery SOC is smaller than the SOC reference range minimum value SOC _min (T04); q4) When the value of i is not N in step q1) (T02-no) or SOC <SOC _min in step q3) (T04-yes), checking whether the index value is 1 (T06) ; q5) If the index value is 1 in step q4) (T06-yes), the power value P _fc obtained from the fuel cell is a predetermined positive number other than 0, and the fuel cell power value P _{fc -rated} is input to the simulator. Set (T07), wherein the power value P _bat obtained from the battery is set to P _d -P _fc ; q6) checking whether the battery SOC is greater than the SOC reference range maximum value SOC _max (T08); q7) If the SOC value is not SOC> SOC _max in step q6) (T08-no) or the battery SOC value is updated (T05), or if the SOC> SOC _max in step q6) (T08-yes), the index value is 2 Updating the battery SOC value after being set (T09) (T05); It is made, including.

Here, as in the foregoing, the power value P _fc obtained from the fuel cell is set to 0, and the power value P _bat obtained from the battery is set to the driving power value P _d . Indicates an unused state. Further, the power value P _fc obtained from the fuel cell is set to the fuel cell power value P _fc-rated which is input to the simulator as a predetermined positive value other than 0, and the power value P _bat obtained from the battery is set to P _d -P _fc . In this case, not only the motor and the gear are driven by the battery but also a predetermined power is driven in the fuel cell, so that the battery and the fuel cell are simultaneously used to drive the motor and the gear. At this time, it is one of the objectives of the simulation to determine the fuel cell power value P _{fc -rated} appropriately, and the P _{fc -rated} value can be determined by various input by the experimenter. By analyzing and analyzing the results obtained using the various P _fc-rated values, it is possible to find the optimal value of the battery power to fuel cell power ratio under certain driving conditions. The final step also indicates that if the battery SOC is above the reference range, it will operate in a mode that maintains its current state without charging the battery.

Finally, the flow up to the rightmost column represents a subsequent control step when the index value is not 1 (T06-no) at the beginning of the flow up to the middle column. In this case, the power distribution control may include r1) checking whether the i value is N (T02); r2) when the i value is N (T02-yes), the power value P _fc obtained from the fuel cell is set to 0, and the power value P _bat obtained from the battery is set to the driving power value P _d (T03); r3) checking whether the battery SOC is smaller than the SOC reference range minimum value SOC _min (T04); r4) When the i value is not N in step r1) (T02-no) or when SOC <SOC _min in step r3) (T04-yes), checking whether the index value is 1 (T06) ; r5) When the index value is not 1 in step r4) (T06-no), whether the driving power value P _d is greater than the fuel cell regulated power value P _fc-rated as a predetermined positive number other than 0 (r0). Confirmed step (T10); r6) When P _d > P _fc-rated in step r5) (T10-yes), the power value P _fc obtained from the fuel cell is set to P _{fc -rated} and the power value P _bat obtained from the battery is P _d − If P _fc is set (T11) and P _d > P _fc-rated in step r5) (T10-no), the power value P _fc obtained from the fuel cell is set to P _d and the power value obtained from the battery. P _bat is set to 0 (T12); r7) checking whether the battery SOC is smaller than the SOC reference range minimum value SOC _min (T13); r8) If SOC <SOC _min in step r7) (T13-no) or the battery SOC value is updated (T05), or if SOC <SOC _min in step r7) (T13-yes) the index value is 1 Updating the battery SOC value after being set (T14) (T05); It is made, including.

Here, as in the foregoing, the power value P _fc obtained from the fuel cell is set to 0, and the power value P _bat obtained from the battery is set to the driving power value P _d . Indicates an unused state. In addition, as before, the power value P _fc obtained from the fuel cell is set to the fuel cell power value P _fc-rated input to the simulator as a predetermined positive value other than 0, and the power value P _bat obtained from the battery is P _d. Setting to P _fc indicates a state in which a predetermined power is driven in the fuel cell instead of driving the motor and gear only by the battery, so that the battery and the fuel cell are simultaneously used to drive the motor and the gear. In addition, that the power value P _fc obtained from the fuel cell is set to P _d and the power value P _bat obtained from the battery is set to 0 indicates that the motor and gear are driven only by the fuel cell without using the battery. That is, if the battery SOC is below the reference range (T04-yes) and is not currently in the state of battery charge (i.e., T06-no when the index value is not 1), then enough driving power can be obtained from the fuel cell (ie P _{If d} > P _{fc -rated} and the required driving power is less than that obtained from the fuel cell, the control is thus performed because it is advantageous to use only the fuel cell without using a T10-no battery. In addition, the last step indicates that if the battery SOC is below the reference range, it will operate in the battery charge mode.

In this power distribution control step, the reference range of the battery SOC may be appropriately determined according to the intention or design of the experimenter, and may be, for example, 0.5 to 0.6 (SOC _min = 0.5, SOC _max = 0.6).

The present invention is not limited to the above-described embodiments, and the scope of application of the present invention is not limited to those of ordinary skill in the art to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Of course, various modifications can be made.
