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 a key category of construction machinery, playing a vital role in numerous fields thanks to their flexible mobility and efficient lifting capacity. Traditional truck cranes are powered by fuel engines, a mature and stable technology. However, significant progress in energy conservation has been limited by the need to improve engine thermal efficiency. In recent years, new energy truck cranes have garnered widespread industry attention due to their high energy efficiency, low operating costs, and environmental friendliness. New energy truck cranes primarily include pure electric and plug-in models. Pure electric truck cranes have received poor market response due to significant cost increases and limited operating conditions. Plug-in models rely entirely on fuel for operation and can operate on either fuel or mains electricity. According to industry data, 85% of a truck crane's fuel consumption is used for operation, while only 15% is used for driving. While plug-in operation can significantly reduce energy consumption, plug-in models require stricter worksite conditions, hindering their widespread adoption. Therefore, improving the energy efficiency of truck cranes while ensuring their adaptability to diverse operating environments has become a pressing issue. Summary of the Invention

[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 2The 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 relatively little 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 driven by the generator 200 to generate electricity. 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 optimal fuel economy is selected as the target following curve. That is, the engine 100 operates along a fixed curve, which is a predetermined optimal fuel economy curve. When the engineering equipment is driving or operating, the engine 100 will operate along this optimal fuel economy curve according to the real-time operating conditions and required power, 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). The generator 200 transmits electrical energy to the generator controller 300 via a three-phase high-voltage wiring harness. The generator controller 300 is connected to the high-voltage distribution box 400 via 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 via a three-phase high-voltage power line and can control the drive motor 700 to drive the operating device 800 to move. It will be understood that this embodiment includes not only high-voltage circuits but also low-voltage communication components. The low-voltage communication relies on 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, enabling information sharing and coordinated control among internal controllers.
[0055] Specifically, the energy control method may include the following steps:
[0056] Step 100: Obtain 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 requires first obtaining relevant information, specifically including the remaining power of the power battery pack 500, the working condition of the engineering equipment, and the operating requirements under the working conditions. Among them, by obtaining the remaining power of the power battery pack 500, the current energy storage status of the power battery pack 500 can be understood. The working conditions include operating conditions, driving conditions, and parking conditions. By obtaining the working conditions of the engineering equipment, it can be determined whether the engineering equipment is currently performing operations, such as excavation, loading, lifting, etc.; or it can be determined whether the engineering equipment is currently driving, and driving can also include forward, backward, and turning, etc.; or it can be determined whether the engineering equipment is currently in a parked 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 a preset lower limit, determining a power supply source for 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 to distribute electrical energy. It can distribute electrical energy to the drive controller 600, enabling the drive controller 600 to control the drive motor 700 to drive the operating device 800. It can also distribute electrical energy 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 electrical energy to the high-voltage distribution box 400. The power supply of the high-voltage distribution box 400 can be the generator 200 or the 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 power required by the operation. 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 power required by the operation. In this case, the power supply can be the power battery pack 500, the 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, affecting the normal operation of the equipment.
[0061] In step 400 , the high-voltage distribution box 400 distributes electric energy to the drive controller 600 based on the operation requirements, 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 source of the high-voltage distribution box 400, the power can be distributed to the drive controller 600 according to the operation requirements through the high-voltage distribution box 400. After receiving the power, 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 utilizing an extended-range system architecture for engineering equipment, energy consumption during operation is significantly reduced with minimal additional cost, thereby enhancing energy conservation and emission reduction during the operation and operation of the engineering equipment. Furthermore, by real-time monitoring of the remaining charge of the power battery pack 500, the operating condition of the engineering equipment, and the operational requirements under those conditions, the power supply source for the high-voltage distribution box 400 is dynamically determined. This allows for the rational distribution of power through the high-voltage distribution box 400, ensuring stable operation of the engineering equipment under various operating conditions and improving its adaptability to diverse operating environments. Furthermore, when the power battery pack 500 is low on charge, it can be recharged by the generator 200, extending the equipment's operating time.
[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 drive axle 810. The first drive controller 610 is connected to the first operating device and the drive 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. The high-voltage distribution box 400 distributes power to the drive controller 600 based on operating requirements, so that the drive controller 600 controls the drive motor 700 to drive the operating device 800 to move. The system includes:
[0065] Distribute electrical energy to the first drive controller 610 and / or the second drive controller 620 based on operational 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 enable the engineering equipment to travel;
[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 may include a main drive motor 710 and a working motor 720. The operating device 800 may include a first working device, a second working device, and a drive axle 810. The first drive controller 610 controls the main drive motor 710, which is connected to the drive axle 810 and can be used to drive the engineering equipment. The main drive motor 710 is also connected to the first working device and can be used to drive the first working device to perform its work tasks. The second drive controller 620 controls the working motor 720, which is connected to the second working device and can be used to drive the second working device to perform its work tasks. It should be understood that the first working device and the second working device are different components that need to move when the engineering equipment performs its work. The first and second working devices can perform the same task simultaneously or separately. The specific configuration of the first and second working devices is 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 the power distribution center, can distribute power to the first drive controller 610 and the second drive controller 620 according to operational requirements. Power distribution can be performed 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 construction 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] This embodiment flexibly distributes power based on operational needs, meeting diverse drive and control requirements. Through precise power distribution and drive control, the operational efficiency and energy utilization efficiency of engineering equipment are improved, while energy consumption is reduced. Furthermore, the relatively independent components of the extended-range system architecture facilitate maintenance and upgrades.

[0073] The main drive motor 710 is controlled to operate by the first drive controller 610;
[0074] Based on the working requirements, the gearbox 1100 is controlled to adjust the transmission ratio between the main drive motor 710 and the drive axle 810, thereby driving the drive axle 810 to enable the engineering equipment to move;
[0075] Alternatively, based on the working requirements, the power take-off 1200 is controlled to obtain power from the gearbox 1100 to drive the hydraulic oil pump 1300 to drive the first working device to move, wherein the first working device includes the support legs 821 or the boom 822;

The working motor 720 includes a luffing motor 721, a hoisting motor 723, and a slewing motor 722. The main drive motor 710 transmits power to the gearbox 1100, which in turn drives the drive axle 810, propelling the construction equipment. The gearbox 1100 is also mechanically connected to the PTO 1200. The PTO 1200, receiving power from the gearbox 1100, drives the hydraulic oil pump 1300, thereby moving the first working device, which includes the outriggers 821 or the boom 822. The second drive controller 620 transmits power to the luffing motor 721, the hoisting motor 723, and the slewing motor 722 via a three-phase high-voltage wiring harness.

[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 operational requirements, thereby optimizing the driving performance of the engineering equipment. When the first operating device is required to move, power is transmitted through the power take-off 1200 and the hydraulic oil pump 1300 to achieve movements such as extension and retraction of the legs 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 slewing motor 722 based on operational requirements to drive the corresponding second operating device to move. For example, during a hoisting operation, it may be necessary to simultaneously control the variable amplitude motor 721 and the slewing motor 722 to achieve precise positioning and angle adjustment of the boom 831; during a lifting operation, the hoisting motor 723 is primarily used to lift or lower the heavy object.
[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. Using a distributed electric drive structure, the engine 100 and the drive motor 700 are completely decoupled. Energy transmission relies on high-voltage wiring harnesses and a small number of mechanical components, significantly improving power transmission efficiency. This makes the layout of the entire power system of the engineering equipment more flexible, adapting to the development needs of different vehicle models and platforms, effectively reducing manufacturing costs and shortening the development cycle. Furthermore, driving and operating are completely driven by electric motors, making the process not only quieter and smoother, but also significantly improving response speed and acceleration performance, enhancing the precision and efficiency of controlling the driving and operation of the engineering equipment.
[0081] In one embodiment, when the remaining power is greater than or equal to a preset lower limit, determining the power supply of the high-voltage distribution box 400 based on the rated power of the engine 100 and the required power in the operation requirement includes:
[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 , determining 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 the power battery pack 500 is used, 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 source of the high-voltage distribution box 400 is the generator 200, so that the operation of the engine 100 drives the generator 200 to generate electricity and provide electrical energy to the high-voltage distribution box 400.
[0087] It should be noted that if the power demand exceeds the rated power of the engine 100, it is necessary to further determine whether the power battery pack 500 can provide sufficient energy to meet the demand. By evaluating the maximum power output of the power battery pack 500 and comparing it with the power demand, if the power provided by the power battery pack 500 meets the power demand, the power battery pack 500 is determined to be the power source for the high-voltage distribution box 400. If the power battery pack 500 cannot meet the power demand alone, the generator 200 and the power battery pack 500 are required to jointly supply power. Working together, the generator 200 and the power battery pack 500 can jointly provide sufficient energy to meet the current operating requirements. In this case, the power battery pack 500 and the generator 200 are determined to be the power sources for the high-voltage distribution box 400. It is understood that when the generator 200 and the power battery pack 500 work together, the power battery pack 500 may discharge according to the rated discharge power, transmitting the energy to the high-voltage distribution box 400, while the generator 200 simultaneously provides power to the high-voltage distribution box 400 to meet the power demand.
[0088] In this embodiment, the power supply is flexibly adjusted according to the current operating requirements and the remaining power of the power battery pack 500 to ensure that the equipment can operate continuously and stably. By optimizing the power supply method, the performance of the engine 100 and the power battery pack 500 can be fully utilized, energy consumption can be reduced, and energy utilization efficiency can be improved. When the power supply is sufficient and the power demand 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 power demand is high, the generator 200 and the power battery pack 500 can be used in conjunction to ensure that the equipment can operate continuously. This improves the operating efficiency and energy utilization efficiency of the engineering equipment and reduces 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 used only 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. 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 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. Therefore, 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 at this time. The power supply source 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 only 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 source 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.

The transmission 1100 adjusts the transmission ratio between the drive motor 700 and the drive axle 810 based on the driving speed and torque requirements to optimize driving performance. When the engineering equipment needs to perform specific operating tasks, the high-voltage distribution box 400 distributes electrical energy to the drive controller 600 based on the operating requirements of the operating conditions.
