Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments obtained based on the embodiments in the disclosure belong to the protection scope of the disclosure.

With the development of the times, the application scenes of the fuel cell become more and more extensive, and particularly, a great development space exists in the field of fuel cell automobiles. In order to enable a fuel cell engine to drive a high-power driving target vehicle, a multi-stack parallel power generation mode is generally adopted in the prior art, and each stack is controlled to operate according to the optimal output power of the stack, so that power is provided for the high-power driving target vehicle. However, such an operation mode tends to cause a large loss to the fuel cell engine, and the output power does not match the target vehicle demand power, wasting fuel resources.

In order to solve the problems, the inventor finds out through research that the output power of the fuel cell system can be reasonably distributed by determining the required power of a target vehicle and combining the condition of the whole vehicle, so that the power generation efficiency of the fuel cell system is ensured to be in a higher efficiency area, and the waste of fuel resources is avoided. In addition, by adopting the method for reasonably distributing the output power according to the power required by the target vehicle, the loss of the galvanic pile is avoided, the service life of the fuel cell is prolonged, and the technical problem that the loss of the fuel cell engine is larger because each galvanic pile runs according to the optimal output power is effectively solved.

Fig. 1 is a schematic diagram of a system architecture based on the present disclosure, and as shown in fig. 1, the system architecture shown in fig. 1 may specifically include a target vehicle 1, a server 2, and a fuel cell system 3, wherein a fuel cell system control device is disposed in the server 2.

The target vehicle 1 may be any high-power driving target vehicle using a fuel cell engine with multiple parallel stacks for power generation, including but not limited to heavy trucks, engineering machinery, mine trucks, and the like.

The fuel cell system control device may be a hardware device mounted on the entire vehicle control unit server, and may be configured to acquire the operating state information of the target vehicle, determine a power demand of the target vehicle based on the operating state information of the target vehicle, and determine the target output power of the fuel cell system based on the power demand.

The fuel cell system 3 may be specifically a multi-stack parallel fuel cell mounted on a fuel cell engine and providing a driving force for a target vehicle.

Further, the fuel cell system control means is for controlling the fuel cell system 3 to operate at the target output power.

Example one

Fig. 2 is a schematic flow chart of a control method of a fuel cell system according to an embodiment of the present disclosure, and as shown in fig. 2, the control method of the fuel cell system according to the embodiment of the present disclosure includes:

step 201, obtaining running state information of a target vehicle, wherein the running state information comprises battery residual capacity and motor power.

The fuel cell system control method according to the present embodiment is executed mainly by the fuel cell system control device described above, and the fuel cell system control device is mounted on a server of a vehicle control unit.

In the present embodiment, in order to avoid the loss of the cell stack due to the excessive output power of the fuel cell system, it is necessary to control the output power of the fuel cell system to match the power demand of the target vehicle. Therefore, in order to determine the power demand value of the target vehicle, the fuel cell system control device may first acquire the running state information of the target vehicle. Specifically, the operation state information may include a battery remaining amount and a motor power.

Step 202, determining the power demand value of the target vehicle according to the running state information.

In the present embodiment, since the fuel cell system is specifically used for the power supply operation for the target vehicle, the calculation of the power demand value of the target vehicle, which is specifically used for maintaining the normal operation of the target vehicle, can be achieved in accordance with the operating state information of the target vehicle. Specifically, after the fuel cell system control device acquires the operating state information of the target vehicle, the calculation of the power demand value may be implemented by any one of power calculation methods according to the battery remaining capacity and the motor power of the target vehicle, which is not limited by the present disclosure.

And 203, determining a target output power corresponding to the fuel cell system according to the power demand value and a plurality of preset power gears corresponding to the fuel cell system.

In the present embodiment, in order to determine the target output power, a plurality of different power steps may be set in advance according to the power output of the fuel cell system in actual use. For example, the plurality of power steps preset by the fuel cell system are respectively 50kW, 60kW, 70kW, 80kW, and the like.

Accordingly, the fuel cell system control device may determine the target output power corresponding to the fuel cell system of the target vehicle among a plurality of power steps preset by the fuel cell system in accordance with the power demand value in order to determine the target output power after determining the power value required to drive the target vehicle. Specifically, one power notch having the smallest difference from the power demand value may be selected among the plurality of power notches as the target output power. Alternatively, the target output power may be selected according to actual conditions in two power steps with the smallest difference from the power demand value among the plurality of power steps, and the like, which is not limited by the present disclosure.

In the above example, if the current power demand of the target vehicle is 75kW, the target vehicle may determine that the target output power of the fuel cell system of the target vehicle is 70kW or 80kW according to a plurality of power gears.

And step 204, controlling the fuel cell system to output the target output power.

In the present embodiment, after determining the target output power, the fuel cell system control device controls the fuel cell system to output the target output power in order to operate the fuel cell system at the target output power.

For example, after a heavy truck of a fuel cell engine using multi-stack parallel power generation is started, the fuel cell system control device may automatically obtain the remaining battery capacity and the motor power of the truck, and determine the power value required for driving the heavy truck according to the remaining battery capacity and the motor power. Next, the fuel cell system control device determines a target output power corresponding to the fuel cell system of the heavy truck from a plurality of power steps preset by the fuel cell system according to the required power value. Finally, the fuel cell system control device controls the fuel cell system of the heavy truck to operate at the target output power.

The fuel cell system control method provided by the embodiment determines the power demand of the target vehicle by acquiring the operating state information of the target vehicle, determines the target output power corresponding to the fuel cell system according to the power demand and a plurality of preset power gears corresponding to the fuel cell system, and controls the fuel cell system to output the target output power. The fuel cell system has the advantages that the power generation efficiency of the fuel cell system is ensured to be in a higher efficiency area, and the waste of fuel resources is avoided. Moreover, by adopting the method for reasonably distributing the output power according to the power required by the target vehicle, the loss of the galvanic pile is avoided, the service life of the fuel cell is prolonged, and the technical problem of large loss of the galvanic pile caused by the fact that each galvanic pile runs according to the optimal output power is effectively solved.

On the basis of the first embodiment, in order to further explain the control method of the fuel cell system of the present disclosure, in the first embodiment, step 203 specifically includes: respectively calculating difference absolute values between the power demand value and the power gears; determining two power gears of which the absolute value of the difference is smaller than a preset difference threshold value to obtain two power gears to be set; and determining the target output power corresponding to the fuel cell system according to the battery residual capacity of the target vehicle and the power gear to be set.

In the present embodiment, in order to determine the target output power corresponding to the fuel cell system of the target vehicle, the fuel cell system control device calculates the absolute value of the difference between the power demand value of the target vehicle and a plurality of power stage values corresponding to the preset fuel cell system, respectively. And if the calculated absolute value of the difference is smaller than a preset difference threshold, the gear is a power gear to be set. According to the method, two power gears to be set are obtained finally. The fuel cell system control device can determine the target output power corresponding to the fuel cell system of the target vehicle in the two power gears to be set according to the battery residual capacity and the actual scene of the target vehicle.

It should be noted that, among a plurality of power gears corresponding to the preset fuel cell system, there is a power gear with the optimal efficiency, and the power gear with the optimal efficiency can be calculated by using any efficiency calculation method, which is not limited in this disclosure. When the power demand of the target vehicle is near the efficiency-optimum power notch, the efficiency-optimum power notch is preferentially determined as the target output power corresponding to the fuel cell system of the target vehicle.

For example, the preset power steps of the fuel cell system of one heavy truck are respectively 50kW, 60kW, 70kW, 80kW, and the like, and the preset difference threshold is 9 kW. If the power demand of the heavy truck is 73kW, the fuel cell system control device calculates absolute values of differences between power steps of 73kW and 50kW, 60kW, 70kW, 80kW, respectively. The calculated absolute values of the difference values are 23kW, 13kW, 3kW, 7kW and the like respectively. Wherein 3kW and 7kW are both less than preset difference threshold value 9kW, then 70kW and 80kW power gears that it corresponds are promptly for waiting to set up the power gear. The fuel cell system control device determines the target output power corresponding to the fuel cell system of the heavy truck in the power ranges of 70kW and 80kW by combining the residual battery capacity of the heavy truck.

In the above example, if the 80kW power shift is the power shift with the optimal efficiency of the heavy truck, and the power demand value of the heavy truck is 73kW, the 80kW power shift is preferentially determined as the target output power corresponding to the fuel cell system of the heavy truck, and the determination does not need to be performed in combination with the remaining battery capacity.

Through the mode, the target output power is accurately determined, so that the target output power is more suitable for the power demand value and the actual scene of a target vehicle, and the loss of a galvanic pile and the waste of fuel resources are further avoided.

Further, on the basis of the first embodiment, step 203 specifically includes: if the residual battery capacity is within a preset first electric quantity range, determining a first power gear to be set which is smaller than the power demand value in the two power gears to be set, and taking the first power gear to be set as the target output power; if the residual electric quantity of the battery is within a preset second electric quantity range, determining a second to-be-set power gear which is larger than the power demand value in the two to-be-set power gears, and taking the second to-be-set power gear as the target output power; wherein the first range of electrical quantities is greater than the second range of electrical quantities.

In the present embodiment, in order to make the determined target output power more suitable for the power demand of the target vehicle and the actual scene where the target vehicle is located, the fuel cell system control device may further determine the target output power based on the battery remaining capacity range of the target vehicle.

Specifically, if the battery remaining amount of the target vehicle is within a preset first amount range, the fuel cell system control device selects a first power range to be set, which is smaller than the power demand value, as the target output power. The fuel cell system control means selects a second power range to be set, which is larger than the power demand value, as the target output power if the battery remaining capacity of the target vehicle is within a preset second capacity range.

It should be noted that the first electric quantity range in this embodiment is larger than the second electric quantity range.

For example, the first preset electric quantity range of a heavy truck is that the remaining battery capacity is above 70%, and the second preset electric quantity range is that the remaining battery capacity is below 50%. The two power gears to be set are 80kW and 90kW respectively. The power demand of the heavy truck was 85 kW. If the remaining battery capacity of the heavy truck is 80% and the remaining battery capacity is high, the fuel cell system control device may select a lower output power as the target output power in two power steps to be set, in order to achieve the purpose of saving fuel resources. That is, a gear of 80kW may be determined as the target output power. If the remaining battery capacity of the heavy truck is 40% and the remaining battery capacity is low, the fuel cell system control device may select a higher output power as the target output power in two power steps to be set in order to enable the heavy truck to operate normally. That is, a gear of 90kW may be determined as the target output power.

By the mode, the actual scene can be better fitted, the target output power can be more reasonably determined, the waste of fuel resources is avoided, and the loss of the galvanic pile is reduced under the condition of ensuring the normal operation of the target vehicle.

Further, on the basis of the first embodiment, step 203 specifically includes: if the residual battery capacity is between a preset first electric quantity range and a preset second electric quantity range, respectively determining efficiency values corresponding to the two power gears to be set according to a preset fuel cell power/efficiency corresponding relation; and determining the target output power corresponding to the fuel cell system according to the efficiency value.

In the present embodiment, the method of determining different output power according to the battery remaining capacity range of the target vehicle is similar to that described above. If the battery residual capacity of the target vehicle is between the preset first electric quantity range and the second electric quantity range, the fuel cell system control device calls the preset fuel cell power/efficiency corresponding relation to inquire, respectively inquires the efficiency values corresponding to the two power gears to be set, and finally determines the target output power corresponding to the fuel cell system by comparing the efficiency values corresponding to the two power gears to be set.

Specifically, the power stage to be set with the higher efficiency value may be selected as the target output power from among the two power stages to be set. On the basis of the first embodiment, the determining the target output power corresponding to the fuel cell system according to the efficiency value includes: and determining the power gear to be set with a high efficiency value in the efficiency values corresponding to the two power gears to be set as the target output power.

In this embodiment, after determining the efficiency values corresponding to the two power steps to be set, the efficiency values corresponding to the two power steps to be set may be compared, and the power step to be set with the higher efficiency value may be determined as the target output power.

For example, if the remaining battery power of the heavy truck is 60%, the fuel cell system control device may call a preset fuel cell power/efficiency corresponding relationship to perform an inquiry, and if the inquired efficiency value corresponding to the 80kW step is greater than the efficiency value corresponding to the 90kW step, finally determine that the 80kW step is the target output power corresponding to the fuel cell system. And finally determining the 90kW gear as the target output power corresponding to the fuel cell system if the efficiency value corresponding to the 80kW gear is less than or equal to the efficiency value corresponding to the 90kW gear.

The fuel cell system control method provided by this embodiment determines a power demand of a target vehicle by acquiring operating state information of the target vehicle, determines a target output power corresponding to a fuel cell system according to the power demand and a plurality of preset power gears corresponding to the fuel cell system, in combination with an actual scene, and controls the fuel cell system to output the target output power. The fuel cell system has the advantages that the power generation efficiency of the fuel cell system is ensured to be in a higher efficiency area, and the waste of fuel resources is avoided. Moreover, by adopting the method for reasonably distributing the output power according to the power required by the target vehicle, the loss of the electric pile is avoided, and the service life of the fuel cell is prolonged.
