Description

Technical Field

[0001] The present application relates to the technical field of engineering equipment, and specifically to an energy control method, device, new energy engineering equipment and a readable storage medium. Background Art

[0002] Truck cranes are an important category of construction machinery. With their flexible mobility and efficient lifting capacity, they play an important role in many fields. Traditional truck cranes all use fuel engines as their power source. The relevant technology is mature and stable, but it is difficult to make significant progress in energy saving due to the improvement of engine thermal efficiency. In recent years, new energy truck cranes have attracted widespread attention in the industry due to their high energy efficiency, low operating costs and environmental protection. New energy truck cranes mainly include pure electric and plug-in models. Among them, pure electric truck cranes have received poor market feedback due to excessive cost increase and limited operating conditions; plug-in models rely entirely on fuel, and operations can be pure fuel or pure mains electricity. According to the statistical results of industry big data, 85% of the fuel consumption of truck cranes is used for operation, and driving fuel consumption accounts for only 15%. Therefore, using plug-in operations can reduce a lot of energy consumption, but plug-in models have high requirements for operating site conditions, which is not conducive to large-scale promotion. Therefore, how to improve the energy utilization rate of truck cranes while taking into account the adaptability of truck cranes to different operating environments has become a widely concerned issue at present.

[0053] Figure 1 The following schematically shows a flow chart of an energy control method according to an embodiment of the present application. Figure 1As shown, an embodiment of the present application provides an energy control method, which is applied to engineering equipment including an extended-range system architecture. The extended-range system architecture includes an engine 100, a generator 200, a generator controller 300, a high-voltage distribution box 400, a power battery pack 500, a drive controller 600, a drive motor 700 and an operating device 800. The engine 100, the generator 200, the generator controller 300 and the high-voltage distribution box 400 are connected in sequence, the high-voltage distribution box 400 is respectively connected to the power battery pack 500 and the drive controller 600, and the drive controller 600, the drive motor 700 and the operating device 800 are connected in sequence.

[0054] refer to Figure 2, the energy control method of the embodiment of the present application is applied to engineering equipment including an extended-range system architecture. Compared with traditional pure fuel engineering equipment, the engineering equipment with the extended-range system architecture can significantly reduce energy consumption during use with less cost increase, thereby improving the energy-saving and emission-reduction effects of the driving and operation of the engineering equipment. Specifically, the extended-range system architecture of the engineering equipment may include an engine 100, a generator 200, a generator controller 300, a high-voltage distribution box 400, a power battery pack 500, a drive controller 600, a drive motor 700, and an operating device 800. Among them, the engine 100 is mechanically connected to the generator 200, and the operation of the engine 100 is controlled to drive the generator 200 to generate electrical energy. In this embodiment, the control of the operation of the engine 100 adopts a power curve following control strategy, and the power curve of the engine 100 at the time of the best fuel economy is selected as the target following curve, that is, the engine 100 runs along a fixed curve, which is a predetermined best fuel economy curve. When the engineering equipment is driving or operating, according to the real-time working conditions and required power, the engine 100 will run along this best fuel economy curve, continuously changing the power value of the engine 100 to ensure that sufficient power is provided while achieving the lowest fuel consumption. The generator 200 can be a FISG generator 200 (Flywheel Integrated Starter Generator, flywheel integrated starter / generator 200). The generator 200 transmits electrical energy to the generator controller 300 through a three-phase high-voltage wire harness, and the generator controller 300 is connected to the high-voltage distribution box 400 through a two-phase high-voltage wire. The high-voltage distribution box 400 can distribute electrical energy to the power battery pack 500 and the drive controller 600. The drive controller 600 is connected to the drive motor 700 through a three-phase high-voltage wire, and can control the drive motor 700 to drive the operating device 800 to move. It can be understood that in this embodiment, not only a high-voltage circuit is included, but also a low-voltage communication part. The low-voltage communication relies on the CAN (Controller Area Network) bus technology. The CAN bus is used to connect the VCU (Vehicle Control Unit), ECU (Electronic Control Unit), RCU (Reduced Complexity Unit), generator controller 300, drive controller 600, etc. Each controller node is responsible for receiving, processing and sending specific control information to achieve information sharing and collaborative control between internal controllers.

[0055] Specifically, the energy control method may include the following steps:

[0056] Step 100, obtaining the remaining power of the power battery pack 500, the working condition of the engineering equipment and the operation requirements under the working condition;

[0057] In this embodiment, it should be noted that the energy control of the engineering equipment needs to first obtain relevant information, including the remaining power of the power battery pack 500, the working condition of the engineering equipment and the operating requirements under the working condition. Among them, the current energy storage state of the power battery pack 500 can be understood by obtaining the remaining power of the power battery pack 500. The working condition includes the operating condition, the driving condition and the parking condition. By obtaining the working condition of the engineering equipment, it can be determined whether the engineering equipment is currently performing operations, such as excavation, loading, lifting and other operations; or determine whether the engineering equipment is currently driving, and driving can also include forward, backward and turning, etc.; or determine whether the engineering equipment is currently in a parking state. By obtaining the operating requirements under the working conditions, the specific tasks that the engineering equipment needs to perform can be determined according to the working conditions, and the required power required for the task can be estimated.

[0058] Step 200, when the remaining power is greater than or equal to the preset lower limit, determine the power supply source of the high-voltage distribution box 400 based on the rated power of the engine 100 and the required power in the operation demand, wherein the power supply source is at least one of the power battery pack 500 and the generator 200;

[0059] Step 300, when the remaining power is less than a preset lower limit, determining that the power supply of the high-voltage distribution box 400 includes the generator 200, and charging the power battery pack 500 through the high-voltage distribution box 400;

[0060] It should be noted that the high-voltage distribution box 400 is used for power distribution. The high-voltage distribution box 400 can distribute power to the drive controller 600 so that the drive controller 600 controls the drive motor 700 to drive the operation device 800 to move, and can also distribute power to the power battery pack 500 to charge the power battery pack 500. The power supply of the high-voltage distribution box 400 is the source device that transmits power to the high-voltage distribution box 400. The power supply of the high-voltage distribution box 400 can be a generator 200 or a power battery pack 500. Specifically, the power supply of the high-voltage distribution box 400 is determined based on the remaining power of the power battery pack 500 and / or the required power in the operation demand. When the remaining power is greater than or equal to the preset lower limit, the power supply of the high-voltage distribution box 400 is determined according to the rated power of the engine 100 and the required power in the operation demand. At this time, the power supply can be a power battery pack 500 or a generator 200, or a combination of the two. When the remaining power is less than the preset lower limit, it is determined that the power supply of the high-voltage distribution box 400 includes the generator 200, and the power battery pack 500 is charged through the high-voltage distribution box 400 to ensure that the power of the power battery pack 500 is not too low and affects the normal operation of the equipment.

[0061] Step 400 , distributes electric energy to the drive controller 600 based on the operation requirements through the high-voltage distribution box 400 , so that the drive controller 600 controls the drive motor 700 to drive the operating device 800 to move.

[0062] It should be noted that after determining the power supply of the high-voltage distribution box 400, the electric energy can be distributed to the drive controller 600 according to the operation requirements through the high-voltage distribution box 400. After receiving the electric energy, the drive controller 600 controls the drive motor 700 to drive the operating device 800 to move, thereby meeting the operation requirements of the engineering equipment.

[0063] In this embodiment, by using the engineering equipment of the extended-range system architecture, the energy consumption during use is greatly reduced based on the small cost increase, and the energy-saving and emission-reduction effect of the driving and operation process of the engineering equipment is improved. And by real-time monitoring of the remaining power of the power battery pack 500, the working condition of the engineering equipment and the operating requirements under the working condition, the power supply of the high-voltage distribution box 400 is dynamically determined, so that the electric energy is reasonably distributed through the high-voltage distribution box 400 to ensure that the engineering equipment can operate stably under various working conditions and improve the adaptability to different working environments. At the same time, when the power battery pack 500 is insufficient, it can also be charged by the generator 200, which prolongs the operating time of the equipment.

[0064] refer to Figure 3 In one embodiment, the drive controller 600 includes a first drive controller 610 and a second drive controller 620, the drive motor 700 includes a main drive motor 710 and an operating motor 720, the operating device 800 includes a first operating device (not shown), a second operating device (not shown) and a driving axle 810, the first drive controller 610 is connected to the first operating device and the driving axle 810 respectively through the main drive motor 710, the second drive controller 620, the operating motor 720 and the second operating device are connected in sequence, and the high-voltage distribution box 400 distributes electric energy to the drive controller 600 based on the operating requirements, so that the drive controller 600 controls the drive motor 700 to drive the operating device 800 to move, including:

[0065] Distribute electric energy to the first drive controller 610 and / or the second drive controller 620 based on operation requirements through the high-voltage distribution box 400;

[0066] The first drive controller 610 controls the main drive motor 710 to drive the first working device to move or drives the drive axle 810 to drive the engineering equipment;

[0067] And / or, the second driving controller 620 controls the working motor 720 to drive the second working device to move.

[0068] In this embodiment, it should be noted that the drive controller 600 may include a first drive controller 610 and a second drive controller 620, the drive motor 700 includes a main drive motor 710 and an operating motor 720, and the operating device 800 includes a first operating device, a second operating device and a driving axle 810. The first drive controller 610 is responsible for controlling the main drive motor 710, which is connected to the driving axle 810 and can be used to drive the engineering equipment to travel; the main drive motor 710 is also connected to the first operating device and can be used to drive the first operating device to perform an operating task. The second drive controller 620 is responsible for controlling the operating motor 720, which is connected to the second operating device and is used to drive the second operating device to perform an operating task. It can be understood that the first operating device and the second operating device are different components that need to move when the engineering equipment performs an operation. The first operating device and the second operating device can perform the same task at the same time, or they can perform different tasks respectively. The specific settings of the first operating device and the second operating device are divided and determined based on the specific structure and application scenario of the engineering equipment, and can be adjusted adaptively.

[0069] It should be noted that the high-voltage distribution box 400, as an electric energy distribution center, can distribute electric energy to the first drive controller 610 and the second drive controller 620 according to the operating requirements. Among them, the electric energy distribution can be carried out independently or simultaneously to meet the needs of different operating devices and driving. The first drive controller 610 can control the main drive motor 710 to drive the first operating device to perform a specific operating task, or control the main drive motor 710 to drive the drive axle 810 to enable the engineering equipment to travel. The second drive controller 620 can control the operating motor 720 to drive the second operating device to perform the same operating task as the first operating device, or perform another specific operating task different from the first operating device.

[0070] In this embodiment, electric energy is flexibly allocated according to the operation requirements to meet different drive and control requirements. Through precise electric energy allocation and drive control, the operation efficiency and energy utilization efficiency of engineering equipment are improved, and energy consumption is reduced. In addition, the system components of the extended-range system architecture are relatively independent, which is convenient for maintenance and upgrading.

[0079] Specifically, the first drive controller 610 controls the operation of the main drive motor 710, and adjusts the transmission ratio of the gearbox 1100 based on the operation requirements, so as to optimize the driving performance of the engineering equipment. When the first working device is required to move, power is transmitted through the power take-off 1200 and the hydraulic oil pump 1300 to achieve the extension, contraction and other actions of the outrigger 821 or the boom 822. The second drive controller 620 controls the operation of at least one of the variable amplitude motor 721, the hoisting motor 723 and the rotary motor 722 according to the operation requirements to drive the corresponding second working device to move. For example, in the hoisting operation, it may be necessary to control the variable amplitude motor 721 and the rotary motor 722 at the same time to achieve the precise positioning and angle adjustment of the boom 831; while in the lifting operation, the hoisting motor 723 is mainly relied on to lift or lower the heavy objects.

[0080] In this embodiment, the independent control of multiple motors and the flexible adjustment of the transmission system can meet the needs of different operating scenarios. The distributed electric drive structure is adopted, the engine 100 is completely decoupled from the drive motor 700, and the energy transmission relies on high-voltage wiring harnesses and a small number of mechanical components. The power transmission efficiency is significantly improved, making the layout of the entire power system of the engineering equipment more flexible, and can adapt to the development needs of different models and platforms, effectively reducing manufacturing costs and shortening the development cycle. And the driving and operation are completely driven by the motor, which is not only quieter and smoother in use, but also significantly improves the response speed and acceleration performance, which improves the accuracy and efficiency of the driving and operation control of the engineering equipment.

[0081] In one embodiment, when the remaining power is greater than or equal to a preset lower limit, the power supply of the high-voltage distribution box 400 is determined based on the rated power of the engine 100 and the required power in the operation requirement, including:

[0082] When the remaining power is greater than or equal to the preset lower limit, if the required power is less than or equal to the rated power of the engine 100, the power supply source of the high-voltage distribution box 400 is determined to be the generator 200;

[0083] If the required power is greater than the rated power of the engine 100, it is determined whether the power provided by the electric energy output by the power battery pack 500 meets the required power;

[0084] When the power provided by the electric energy output by the power battery pack 500 meets the required power, the power supply source of the high-voltage distribution box 400 is determined to be the power battery pack 500;

[0085] When the power provided by the electric energy output by the power battery pack 500 does not meet the required power, the power supply source of the high-voltage distribution box 400 is determined to be the power battery pack 500 and the generator 200 .

[0086] In this embodiment, it should be noted that by judging whether the remaining power of the power battery pack 500 is greater than or equal to the preset lower limit, it is ensured that before using the power battery pack 500, its remaining power is sufficient to support the current operating needs, so as to avoid the shutdown of engineering equipment or performance degradation due to low power. Specifically, when the remaining power is greater than or equal to the preset lower limit, the current required power is compared with the rated power of the engine 100. If the required power is less than or equal to the rated power of the engine 100, it means that the engine 100 can meet the current operating needs alone. At this time, it can be determined that the power supply of the high-voltage distribution box 400 is the generator 200, so that the generator 200 can be driven by the operation of the engine 100 to generate electricity and provide electrical energy to the high-voltage distribution box 400.

[0087] It should be noted that if the required power is greater than the rated power of the engine 100, it is necessary to further determine whether the power battery pack 500 can provide enough power to meet the demand. By evaluating the maximum power that the power battery pack 500 can currently output and comparing it with the required power, if the power that the power battery pack 500 can provide meets the required power, it is determined that the power supply source of the high-voltage distribution box 400 is the power battery pack 500. If the power battery pack 500 cannot meet the required power alone, the generator 200 and the power battery pack 500 need to be powered together. Through collaborative work, the generator 200 and the power battery pack 500 can jointly provide enough power to meet the current operating requirements. At this time, it is determined that the power supply source of the high-voltage distribution box 400 is the power battery pack 500 and the generator 200. It can be understood that when the generator 200 and the power battery pack 500 work together, the power battery pack 500 can be discharged according to the rated discharge power, and the electric energy is transmitted to the high-voltage distribution box 400, and the generator 200 is used to compensate the high-voltage distribution box 400 for power supply to meet the required power.

[0088] In this embodiment, the power supply is flexibly adjusted according to the current operation requirements and the remaining power of the power battery pack 500, which can ensure that the equipment can operate continuously and stably. And by optimizing the power supply method, the performance of the engine 100 and the power battery pack 500 can be fully utilized to reduce energy consumption and improve energy utilization efficiency. When the power is sufficient and the required power is low, the generator 200 can be used alone to supply power, reducing the loss of the power battery pack 500 and extending its service life; when the required power is high, the generator 200 and the power battery pack 500 can be used in coordination to ensure that the equipment can operate continuously. Thereby improving the operating efficiency and energy utilization efficiency of the engineering equipment and reducing the operating costs.

[0089] In one embodiment, when the remaining power is less than a preset lower limit, determining that the power supply source of the high-voltage distribution box 400 includes the generator 200, and charging the power battery pack 500 through the high-voltage distribution box 400 includes:

[0090] When the remaining power is less than the preset lower limit, if the required power is less than or equal to the rated power of the engine 100, the power supply source of the high-voltage distribution box 400 is determined to be the generator 200, and the power battery pack 500 is charged through the high-voltage distribution box 400;

[0091] When the remaining power is less than the preset lower limit, if the required power is greater than the rated power of the engine 100, the power supply source of the high-voltage distribution box 400 is determined to be the generator 200, and the high-voltage distribution box 400 is controlled to be only used to charge the power battery pack 500 until the remaining power is greater than the preset working value, and the power supply source of the high-voltage distribution box 400 is determined to be the power battery pack 500 and the generator 200.

[0092] In this embodiment, it should be noted that, when the remaining power is less than the preset lower limit, if the required power is less than or equal to the rated power of the engine 100, it means that although the remaining power of the power battery pack 500 is low, the engine 100 can still meet the current operating needs alone. Determine that the power supply source of the high-voltage distribution box 400 is the generator 200, and charge the power battery pack 500 through the high-voltage distribution box 400 to restore its power as soon as possible. It should be noted that in this case, the generator 200 must meet the operating needs and charge the power battery pack 500, so it may be necessary to adjust the output power of the generator 200 in real time based on the optimal fuel economy curve to ensure that both are properly powered.

[0093] It should be noted that when the remaining power is less than the preset lower limit, the required power is greater than the rated power of the engine 100, which means that the engine 100 cannot meet the current operating requirements alone. The power supply of the high-voltage distribution box 400 is determined to be the generator 200, but at this time the generator 200 is mainly used to charge the power battery pack 500, rather than directly providing power for the operation. The high-voltage distribution box 400 is controlled to be used only to charge the power battery pack 500 until the remaining power is greater than the preset working value. It is understandable that the preset working value is set higher than the preset lower limit to ensure that the power battery pack 500 has enough power to support the operating requirements. Once the remaining power of the power battery pack 500 reaches the preset working value, it can be determined that the power supply of the high-voltage distribution box 400 is the power battery pack 500 and the generator 200, and the two work together to meet the current operating requirements.

[0094] In this embodiment, a reliable power supply strategy is provided for the case where the remaining power of the power battery pack 500 is low, thereby improving the operating efficiency and energy utilization efficiency of engineering equipment, reducing operating costs, and extending the service life of the power battery pack 500.
