[0002] This application claims the benefit of Chinese Patent Application No. 202411883375.7, filed on December 19, 2024, the contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of engineering equipment technology, specifically to an energy control method, device, new energy engineering equipment, and readable storage medium. Background Technology

[0004] Truck cranes are an important category of construction machinery, playing a vital role in numerous fields due to their flexible mobility and efficient lifting capacity. Traditional truck cranes all use internal combustion engines as their power source. While the related technology is mature and stable, significant progress in energy conservation is limited by the slowdown in improving engine thermal efficiency. In recent years, new energy truck cranes have received widespread attention in the industry due to their high energy efficiency, low operating costs, and environmental friendliness. New energy truck cranes mainly include pure electric and plug-in hybrid models. Pure electric truck cranes have received poor market feedback due to excessive cost increases and limited operating conditions. Plug-in hybrid models rely entirely on fuel for operation, but can operate using either pure fuel or AC power. According to industry big data statistics, 85% of a truck crane's fuel consumption is used for operation, while fuel consumption for driving accounts for only 15%. Therefore, using plug-in hybrids can significantly reduce energy consumption. However, plug-in hybrid models have higher requirements for on-site conditions, hindering large-scale promotion. Therefore, how to improve the energy utilization rate of truck cranes while ensuring their adaptability to different operating environments has become a widely concerned issue.

[0023] If the remaining power is greater than or equal to the preset lower limit, and the required power is less than or equal to the rated power of the engine, then the power supply for the high-voltage distribution box is determined to be the generator.

[0024] If the required power is greater than the engine's rated power, then determine whether the power provided by the electrical energy output from the power battery pack meets the required power.

[0025] If the power supplied by the electrical energy output from the power battery pack meets the required power, the power supply for the high-voltage distribution box is determined to be the power battery pack.

[0026] When the power supplied by the electrical energy output from the power battery pack is insufficient to meet the required power, the power supply for the high-voltage distribution box is determined to be the power battery pack and the generator.

[0028] If the remaining power is less than the preset lower limit, and the required power is less than or equal to the rated power of the engine, then the power supply of the high-voltage distribution box is determined to be the generator, and the power battery pack is charged through the high-voltage distribution box.

[0029] If the remaining power is less than the preset lower limit, but the required power is greater than the engine's rated power, then the power supply of the high-voltage distribution box is determined to be the generator. The high-voltage distribution box is controlled to be used only to charge the power battery pack until the remaining power is greater than the preset working value. Then, the power supply of the high-voltage distribution box is determined to be the power battery pack and the generator.

[0054] Figure 1 schematically illustrates a flowchart of an energy control method according to an embodiment of this application. As shown in Figure 1, this application provides an energy control method applied to engineering equipment including a range-extended system architecture. The range-extended 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 a running device 800. The engine 100, generator 200, generator controller 300, and high-voltage distribution box 400 are connected sequentially. The high-voltage distribution box 400 is connected to the power battery pack 500 and the drive controller 600, respectively. The drive controller 600, drive motor 700, and running device 800 are connected sequentially.

[0055] Referring to Figure 2, the energy control method of this application embodiment is applied to engineering equipment including a range-extended system architecture. Compared with traditional pure fuel engineering equipment, the range-extended system architecture can significantly reduce energy consumption during use with a smaller cost increase, thereby improving the energy-saving and emission-reduction efficiency of the engineering equipment during driving and operation. Specifically, the range-extended 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 a running device 800. Among them, the engine 100 is mechanically connected to the generator 200, and the generator 200 is driven to generate electrical energy by controlling the operation of the engine 100. In this embodiment, the control of engine 100 operation adopts a power curve following control strategy, and selects the engine 100 power curve at the optimal fuel economy as the target following curve. That is, engine 100 runs along a fixed curve, which is a pre-determined optimal fuel economy curve. When the engineering equipment is driving or operating, according to the real-time working conditions and power demand, engine 100 will run along this optimal fuel economy curve, continuously changing the power value of engine 100 to ensure sufficient power while achieving the lowest fuel consumption. Generator 200 can be FISG generator 200 (Flywheel Integrated Starter Generator 200). Generator 200 transmits electrical energy to generator controller 300 through a three-phase high-voltage wiring harness. Generator controller 300 is connected to high-voltage distribution box 400 through two-phase high-voltage wires. High-voltage distribution box 400 can distribute electrical energy to power battery pack 500 and drive controller 600. The drive controller 600 is connected to the drive motor 700 via a three-phase high-voltage wire, and can control the drive motor 700 to drive the operating device 800 to move. It is understood that this embodiment includes not only a high-voltage circuit but also a low-voltage communication section. The low-voltage communication relies on CAN (Controller Area Network) bus technology. The CAN bus is used to connect 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, realizing information sharing and collaborative control between internal controllers.

[0056] Specifically, the energy control method may include the following steps:

[0057] Step 100: Obtain the remaining power of the power battery pack 500, the operating condition of the engineering equipment, and the operational requirements under the operating condition.

[0058] In this embodiment, it should be noted that energy control of the engineering equipment requires obtaining relevant information first, specifically including the remaining charge of the power battery pack 500, the operating condition of the engineering equipment, and the operational requirements under the operating condition. Obtaining the remaining charge of the power battery pack 500 reveals its current energy storage status. Operating conditions include working conditions, driving conditions, and parking conditions. Obtaining the operating condition of the engineering equipment determines whether it is currently performing work, such as excavation, loading, or hoisting; or whether it is currently driving (driving can include forward, backward, and turning); or whether it is currently parked. Obtaining the operational requirements under the operating conditions allows for the determination of the specific tasks the engineering equipment needs to perform and the estimation of the required power for those tasks.

[0059] Step 200: 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 requirements. The power supply is at least one of the power battery pack 500 and the generator 200.

[0060] Step 300: When the remaining power is less than the preset lower limit, determine that the power supply of the high voltage distribution box 400 includes the generator 200, and charge the power battery pack 500 through the high voltage distribution box 400.

[0061] 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, enabling the drive controller 600 to control the drive motor 700 to drive the operating device 800, or it can distribute power to the power battery pack 500 to charge the power battery pack 500. The power supply for the high-voltage distribution box 400 is the source device that supplies power to it. The power supply for the high-voltage distribution box 400 can be either the generator 200 or the power battery pack 500. Specifically, the power supply for the high-voltage distribution box 400 is determined based on the remaining charge of the power battery pack 500 and / or the required power in the operational requirements. When the remaining charge is greater than or equal to a preset lower limit, the power supply for the high-voltage distribution box 400 is determined based on the rated power of the engine 100 and the required power in the operational requirements. In this case, the power supply can be the power battery pack 500, the generator 200, or a combination of both. When the remaining power is less than the preset lower limit, the power supply of the high-voltage distribution box 400 is determined to include the generator 200, and the power battery pack 500 is charged through the high-voltage distribution box 400 to ensure that the power battery pack 500 is not too low and affects the normal operation of the equipment.

[0062] Step 400: Based on the work requirements, the high-voltage distribution box 400 distributes electrical energy to the drive controller 600 so that the drive controller 600 controls the drive motor 700 to drive the running device 800 to move.

[0063] It should be noted that after determining the power supply of the high-voltage distribution box 400, electrical energy can be distributed to the drive controller 600 according to the operational requirements through the high-voltage distribution box 400. After receiving the electrical energy, the drive controller 600 controls the drive motor 700 to drive the operating device 800 to move, thereby meeting the operational requirements of the engineering equipment.

[0064] In this embodiment, by utilizing a range-extended system architecture, the energy consumption during use is significantly reduced with minimal cost increase, improving the energy-saving and emission-reduction efficiency of the engineering equipment during operation. 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 to the high-voltage distribution box 400 is dynamically determined. This allows for the rational distribution of electrical energy through the high-voltage distribution box 400, ensuring stable operation of the engineering equipment under various conditions and enhancing its adaptability to different working environments. Simultaneously, when the power battery pack 500 is low on charge, it can be charged by the generator 200, extending the equipment's operating time.

[0065] Referring 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 a working motor 720, and the running device 800 includes a first working device (not shown), a second working device (not shown), and a drive axle 810. The first drive controller 610 is connected to the first working device and the drive axle 810 respectively through the main drive motor 710. The second drive controller 620, the working motor 720, and the second working device are connected in sequence. Power is distributed to the drive controller 600 through the high-voltage distribution box 400 based on the work requirements, so that the drive controller 600 controls the drive motor 700 to drive the running device 800 to move, including:

[0066] Power is distributed to the first drive controller 610 and / or the second drive controller 620 through the high-voltage distribution box 400 based on the work requirements.

[0067] The first drive controller 610 controls the main drive motor 710 to drive the first working device to move or drive the drive axle 810 to make the engineering equipment move.

[0068] And / or, the second working device is driven to move by the working motor 720 controlled by the second drive controller 620.

[0069] In this embodiment, it should be noted that the drive controller 600 may include two types: a first drive controller 610 and a second drive controller 620. The drive motor 700 includes a main drive motor 710 and a working motor 720. The running device 800 includes 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 work tasks. The second drive controller 620 controls the working motor 720, which is connected to the second working device and is used to drive the second working device to perform work tasks. It is understood that the first working device and the second working device are different components that need to move when the engineering equipment performs work. The first working device and the second working device can perform the same task simultaneously or perform different tasks separately. The specific settings of the first working device and the second working device are divided and determined based on the specific structure and application scenario of the engineering equipment and can be adjusted adaptively.

[0070] It should be noted that the high-voltage distribution box 400, acting as a power distribution center, can allocate power to the first drive controller 610 and the second drive controller 620 according to operational needs. Power allocation can be performed independently or simultaneously to meet the requirements of different working devices and travel. The first drive controller 610 can control the main drive motor 710 to drive the first working device to perform a specific work task, or control the main drive motor 710 to drive the drive axle 810, enabling the engineering equipment to travel. The second drive controller 620 can control the working motor 720 to drive the second working device to perform the same work task as the first working device, or perform a different specific work task than the first working device.

[0071] In this embodiment, electrical energy is flexibly allocated according to operational needs to meet different drive and control requirements. Through precise power allocation and drive control, the operating efficiency and energy utilization efficiency of the engineering equipment are improved, and energy consumption is reduced. Furthermore, the system components of the range-extended system architecture are relatively independent, facilitating maintenance and upgrades.

[0072] Referring again to Figure 3, specifically, in one embodiment, the range extender system architecture further includes a luffing motor cylinder 1000, a gearbox 1100, a power take-off (PTO) 1200, and a hydraulic oil pump 1300. The working motor 720 includes a luffing motor 721, a winch motor 723, and a slewing motor 722. The main drive motor 710, gearbox 1100, PTO 1200, hydraulic oil pump 1300, and first working device are connected in sequence. The gearbox 1100 is connected to the drive axle 810. The second drive controller 620 is connected to the luffing motor 721, the winch motor 723, and the slewing motor 722 respectively. The luffing motor 721 is connected to the luffing motor cylinder 1000.

[0073] The first drive controller 610 controls the main drive motor 710 to drive the first working device or drive the drive axle 810 to make the engineering equipment move, including:

[0074] The main drive motor 710 is controlled by the first drive controller 610.

[0075] Based on the operational requirements, the control gearbox 1100 adjusts the transmission ratio between the main drive motor 710 and the drive axle 810, thereby driving the drive axle 810 to make the engineering equipment move.

[0076] Alternatively, based on the operational requirements, the power take-off 1200 can obtain power from the gearbox 1100 to drive the hydraulic oil pump 1300 to move the first working device, wherein the first working device includes outriggers 821 or boom 822.

[0077] The second drive controller 620 controls the working motor 720 to drive the second working device to move, including:

[0078] The second drive controller 620 controls at least one of the luffing motor 721, the winch motor 723, and the slewing motor 722 to drive the corresponding second working device to move. The second working device includes a boom 831 or a winch 832. The luffing motor 721 is used to drive the boom 831 to perform luffing motion through the luffing motor cylinder 1000. The winch motor 723 is used to drive the winch 832 to move. The slewing motor 722 is used to drive the boom 831 to perform slewing motion.

[0079] In this embodiment, it should be noted that the range-extended system architecture also includes a luffing motor cylinder 1000, a gearbox 1100, a power take-off (PTO) 1200, and a hydraulic pump 1300. The working motor 720 includes a luffing motor 721, a winch motor 723, and a slewing motor 722. The main drive motor 710 transmits power to the gearbox 1100, which then drives the drive axle 810 to move the engineering equipment. The gearbox 1100 is also mechanically connected to the PTO 1200. The PTO 1200, by receiving power from the gearbox 1100, drives the hydraulic pump 1300 to move the first working device, which includes outriggers 821 or a boom 822. The second drive controller 620 transmits electrical energy to the luffing motor 721, the winch motor 723, and the slewing motor 722 via a three-phase high-voltage wiring harness. The luffing motor 721 is mechanically connected to the luffing motor cylinder 1000. The second working device includes a boom 831 or a winch 832. A luffing motor 721 is used to drive the boom 831 to perform luffing motion through a luffing motor cylinder 1000. A winch motor 723 is used to drive the winch 832 to move. A slewing motor 722 is used to drive the boom 831 to perform slewing motion.

[0080] 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 to optimize the driving performance of the engineering equipment. When the first working device needs to move, power is transmitted through the power take-off 1200 and the hydraulic pump 1300 to achieve actions such as extending and retracting the outriggers 821 or the boom 822. The second drive controller 620 controls at least one of the luffing motor 721, the winch motor 723, and the slewing motor 722 to drive the corresponding second working device to move, according to operational requirements. For example, in hoisting operations, it may be necessary to control the luffing motor 721 and the slewing motor 722 simultaneously to achieve precise positioning and angle adjustment of the boom 831; while in lifting operations, the winch motor 723 is mainly relied upon for lifting or lowering heavy objects.

[0081] In this embodiment, the independent control of multiple motors and flexible adjustment of the transmission system can meet the needs of different operating scenarios. Adopting a distributed electric drive structure, the engine 100 and 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, adaptable to the development needs of different vehicle models and platforms, effectively reducing manufacturing costs and shortening the development cycle. Furthermore, since driving and operation are entirely driven by electric motors, the process is not only quieter and smoother, but also significantly improved in response speed and acceleration performance, enhancing the accuracy and efficiency of controlling the driving and operation of the engineering equipment.

[0082] In one embodiment, when the remaining power is greater than or equal to a preset lower limit, the power supply for the high-voltage distribution box 400 is determined based on the rated power of the engine 100 and the required power in the operational requirements, including:

[0083] If the remaining power is greater than or equal to the preset lower limit, and the required power is less than or equal to the rated power of engine 100, then the power supply of high voltage distribution box 400 is determined to be generator 200.

[0084] If the required power is greater than the rated power of the engine 100, then determine whether the power provided by the electrical energy output from the power battery pack 500 meets the required power.

[0085] If the power supplied by the electrical energy output from the power battery pack 500 meets the required power, the power supply for the high-voltage distribution box 400 is determined to be the power battery pack 500.

[0086] If the power supplied by the electrical energy output from the power battery pack 500 is insufficient to meet the required power, the power supply for the high-voltage distribution box 400 is determined to be the power battery pack 500 and the generator 200.

[0087] In this embodiment, it should be noted that by determining whether the remaining charge of the power battery pack 500 is greater than or equal to a preset lower limit, it is ensured that the remaining charge of the power battery pack 500 is sufficient to support the current operational needs before use, thus avoiding equipment downtime or performance degradation due to low charge. Specifically, when the remaining charge is greater than or equal to the preset lower limit, the current power demand is compared with the rated power of the engine 100. If the power demand is less than or equal to the rated power of the engine 100, it indicates that the engine 100 can independently meet the current operational needs. In this case, it can be determined that the power supply for the high-voltage distribution box 400 is the generator 200, so that the generator 200 is driven by the engine 100 to generate electricity and provide power to the high-voltage distribution box 400.

[0088] It should be noted that if the required power exceeds the rated power of the engine 100, it is necessary to further determine whether the power battery pack 500 can provide sufficient electrical energy to meet the demand. By evaluating the maximum output power of the power battery pack 500 and comparing it with the required power, if the power provided by the power battery pack 500 meets the required power, then the power supply for the high-voltage distribution box 400 is determined to be the power battery pack 500. If the power battery pack 500 cannot meet the required power alone, then the generator 200 and the power battery pack 500 need to work together to provide power. Through coordinated operation, the generator 200 and the power battery pack 500 can jointly provide sufficient electrical energy to meet the current operational needs. In this case, the power supply for the high-voltage distribution box 400 is determined to be 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 discharge at its rated discharge power to deliver electrical energy to the high-voltage distribution box 400, while the generator 200 compensates for the power supply to the high-voltage distribution box 400 to meet the required power.

[0089] In this embodiment, the power supply is flexibly adjusted according to the current operational needs and the remaining charge of the power battery pack 500, ensuring continuous and stable operation of the equipment. By optimizing the power supply method, the performance of the engine 100 and the power battery pack 500 can be fully utilized, reducing energy consumption and improving energy efficiency. When the power supply is sufficient and the power demand is low, the generator 200 can be used alone to reduce the wear and tear on the power battery pack 500 and extend its lifespan. When the power demand is high, the generator 200 and the power battery pack 500 can be used in tandem to ensure continuous operation of the equipment. This improves the operational efficiency and energy utilization efficiency of the engineering equipment and reduces operating costs.

[0090] In one embodiment, when the remaining power is less than a preset lower limit, it is determined that the power supply to 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, including:

[0091] If the remaining power is less than the preset lower limit, and the required power is less than or equal to the rated power of the engine 100, then the power supply 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.

[0092] If the remaining power is less than the preset lower limit, and the required power is greater than the rated power of the engine 100, then the power supply of the high-voltage distribution box 400 is determined to be the generator 200. 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. Then the power supply of the high-voltage distribution box 400 is determined to be the power battery pack 500 and the generator 200.

[0093] In this embodiment, it should be noted that if the remaining battery power is less than a preset lower limit, and the required power is less than or equal to the rated power of the engine 100, then even though the remaining battery power of the power battery pack 500 is low, the engine 100 can still meet the current operational needs independently. The power supply for 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 charge as quickly as possible. It should be noted that in this situation, the generator 200 needs to meet both operational 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 receive adequate power.

[0094] It should be noted that if the remaining battery power is less than the preset lower limit, but the required power exceeds the rated power of engine 100, it means that engine 100 alone cannot meet the current operational needs. The power supply for high-voltage distribution box 400 is determined to be generator 200, but at this time, generator 200 is mainly used to charge the power battery pack 500, not to directly provide power for the operation. High-voltage distribution box 400 is controlled to only charge the power battery pack 500 until the remaining battery power exceeds the preset operating value. It is understood that the preset operating value is set higher than the preset lower limit to ensure that the power battery pack 500 has sufficient power to support the operational needs. Once the remaining battery power of the power battery pack 500 reaches the preset operating value, the power supply for high-voltage distribution box 400 can be determined to be both the power battery pack 500 and generator 200, working together to meet the current operational needs.

[0095] In this embodiment, a reliable power supply strategy is provided for situations where the remaining power of the power battery pack 500 is low, which improves the operating efficiency and energy utilization efficiency of the engineering equipment, reduces operating costs, and extends the service life of the power battery pack 500.

[0096] In one embodiment, the range-extended system architecture further includes an electric accessory 1400, a drive controller 600 connected to the electric accessory 1400, and an energy control method further including:

[0097] The electrical accessory 1400 is controlled by the drive controller 600.

After receiving electrical energy, the drive controller 600 controls the drive motor 700 to operate, and the gearbox 1100 adjusts the transmission ratio between the drive motor 700 and the drive axle 810 according to the driving speed and torque requirements to optimize driving performance. When the engineering equipment needs to perform a specific task, the high-voltage distribution box 400 distributes electrical energy to the drive controller 600 according to the operational requirements under the working conditions. The drive controller 600 simultaneously controls the operation of the drive motor 700 and the power take-off (PTO) 1200.
