Description

Technical Field

[0001] The present invention relates to the technical field of heavy truck energy management, and in particular to a heavy truck full life cycle energy management system and method. Background Art

[0002] Currently, heavy-duty trucks worldwide are focused on improving energy efficiency in individual areas, such as engines, fuel, and operational efficiency. Efforts are being made to improve engine efficiency, conserve fuel, and reduce inefficient operations. Energy management is not considered from a systemic, vehicle-wide, operational-efficiency, or full lifecycle perspective. Even where energy management is addressed, it is fragmented and localized, lacking a comprehensive, life-cycle approach to the vehicle.

[0003] The shortcomings of the prior art are as follows: There are many types of energy-saving technologies, but no systematic diagram has been formed, resulting in low efficiency; The production model of multiple suppliers and factory assembly of complete machines leads to decentralized energy management and low efficiency; Failure to design the vehicle's energy plan from the perspective of the entire vehicle system and its entire life cycle; Decentralized systems have greater energy losses and higher costs; Drivers and car owners have relatively low awareness and insufficient knowledge of comprehensive energy management.

[0004] This patented invention addresses these issues by establishing an energy management system for the entire vehicle lifecycle, from design to end-of-life. This system also considers each energy-consuming aspect of a heavy-duty truck from a granular perspective to a holistic approach, creating a systematic, integrated energy solution that significantly improves the energy efficiency of heavy-duty trucks. This is because energy management for heavy-duty trucks is more valuable than for smaller vehicles like private cars. Summary of the Invention

[0005] The present invention provides a heavy-duty truck full life cycle energy management system and method to solve the problems raised by the above background technology.

[0006] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions: A full life cycle energy management system for heavy trucks includes the addition of a master control system, an energy module, a life cycle analysis module, and a standardized integrated design to the original vehicle accessories and systems. The master control system is used to connect the energy modules and formulate energy-saving plans for the entire vehicle and independent systems based on big data analysis to achieve energy collection, storage, and optimized distribution. The energy module includes an energy recovery module, an energy collection module, and an energy storage module. The life cycle analysis module is used to conduct a full-process analysis of energy utilization and consumption from the design of the entire vehicle to the scrapping stage, including the energy distribution of the entire vehicle, the energy consumption of the independent system, the energy changes during driving, and the energy data of the entire life cycle.

[0007] The beneficial effects of the present invention compared to the prior art are: Looking at the current energy recycling of heavy trucks at home and abroad, only some auxiliary energy recovery management is carried out on a single unit, such as downhill kinetic energy recovery, heat recovery, etc. There is no overall planning and design, and the recovery and comprehensive utilization are also scattered and the efficiency is very low.

[0008] This system analyzes and optimizes design solutions, establishes a large database, develops and establishes energy recovery solutions for each unit, and then designs comprehensive energy utilization solutions from the perspective of the entire vehicle life cycle and the entire system.

[0009] It is worth mentioning that the present invention also includes a heavy truck independent energy-saving management method: Collect multi-dimensional energy consumption data for the entire vehicle, independent systems, and driving conditions; Establish a database including energy sources (diesel / methanol / pure electricity / liquid ammonia, etc.), utilization efficiency and recovery technology; The layout design and simulation verification of the energy management system are completed simultaneously during the new vehicle R&D stage.

[0010] Combined with this method, the present invention has the following beneficial effects compared to the prior art: Based on the system, a combination of methods can be used to achieve data collection, data integration and calculation of various energy consumption and recovery data. In addition, external energy collection data can be further added to the system through the collection of conversion data such as solar energy and wind energy. This complies with the ECE R49 international vehicle standard. Combined with the feedback module in the system, real-time visualization of vehicle energy consumption and energy recovery can be achieved, and data processing can be performed. The above data can all be collected and organized as heavy truck driving data for big data analysis. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In the present invention, in response to the existing technical problems such as the production model of multiple manufacturers supplying and the whole machine factory assembling, the energy management is decentralized and inefficient; there is no energy planning for the vehicle from the perspective of the entire vehicle system and the entire life cycle; the decentralized system leads to greater energy loss and higher costs; drivers and owners have relatively low awareness and insufficient knowledge of comprehensive energy management, etc., a heavy-duty truck full life cycle energy management system is provided, and a supporting usage method is provided. By analyzing and optimizing the design scheme, a large database is established, and energy recovery schemes for each unit are developed and established, and then an energy comprehensive utilization scheme is designed from the perspective of the entire vehicle life cycle and the entire system.

[0018] The following describes in detail an embodiment of the heavy-duty truck full life cycle energy management system of the present invention with reference to the accompanying drawings.

[0019] See also Figures 1-3 A full-lifecycle energy management system for heavy-duty trucks includes a master control system, energy modules, a lifecycle analysis module, and standardized integrated design, all based on original vehicle parts and systems. The master control system connects the energy modules and formulates energy-saving plans for the entire vehicle and independent systems based on big data analysis, achieving energy collection, storage, and optimized distribution. The energy modules include an energy recovery module, an energy collection module, and an energy storage module. The lifecycle analysis module analyzes the entire process of energy utilization and consumption from vehicle design to scrapping, including vehicle energy distribution, independent system energy consumption, energy changes during driving, and full lifecycle energy data. By analyzing and optimizing design solutions, establishing a large database, and developing energy recovery plans for each unit, a comprehensive energy utilization plan is designed from the perspective of the entire vehicle lifecycle and the entire system.

[0020] The energy recovery module includes a kinetic energy recovery module, a thermal energy recovery module and an electric energy recovery module. The kinetic energy recovery module includes a kinetic energy recovery device provided at the power wheel of the heavy truck and used in conjunction with a sensor. The kinetic energy recovery device can absorb the kinetic energy generated when the power wheel of the truck rotates and convert it into electrical energy and store it in the energy storage module. The thermal energy recovery module includes a thermal energy conversion device provided inside the heavy truck. The thermal energy conversion device is used to convert the excess heat energy generated in the heavy truck into electrical energy and store it in the energy storage module. The electric energy recovery module is provided in the internal circuit system of the heavy truck and includes a capacitor energy storage device and a detection device.

[0021] During actual use, this system can detect that the vehicle is in a downhill state through the main control system when the vehicle is going downhill, and the kinetic energy recovery device sensor installed at the power wheel of the heavy truck is activated to start the kinetic energy recovery device, which absorbs the mechanical energy generated by the rotation of the vehicle's power wheel and converts it into electrical energy through a simple power generation method, and stores it in the energy storage device through the transmission line. The energy storage device in this system includes a device that can store electrical energy composed of existing technologies such as batteries and transformers.

[0022] During actual use of this system, when the vehicle is driving, the main control system detects that the vehicle has been driving for a long time and can issue a command to start the heat energy recovery module. The heat energy recovery module can absorb heat energy from the vehicle during driving, including but not limited to exhaust pipe heat, engine heat, brake pad heat, air conditioning compressor heat and air conditioning radiator heat, through heat recovery devices such as spiral tubes and special materials. The heat medium (such as gas, liquid, etc.) in the heat energy recovery device is used to make the heat medium move during the heating process and transfer it to the generator to generate electricity. It can then be stored in the energy storage device through the transmission line. The energy storage device in this system includes a device that can store electrical energy composed of existing technologies such as batteries and transformers.

[0023] During actual use of this system, when the vehicle is driving and the master control system detects a large current overload in the vehicle's internal circuit, it will issue a command to start the energy recovery module. The DC / DC converter will transfer part of the electrical energy to the capacitor energy storage device, and then to the energy storage module for storage.

[0024] The system also includes an energy collection module, which includes a wind energy collection module and a solar energy collection module. The wind energy collection module includes a wind turbine installed on the outside of the heavy truck and a wind energy storage circuit. The wind energy storage circuit can store the electricity generated by the wind turbine in the energy storage module. The solar energy collection module includes a perovskite solar panel installed on the outside of the heavy truck and a solar energy storage circuit. The solar energy storage circuit can store the electricity generated by the perovskite solar panel in the energy storage module.

[0025] During actual use of this system, when the vehicle is outdoors or exposed to sunlight, the overall control system can know through the temperature and brightness sensors that the solar energy collection module is activated, and the solar energy storage circuit can store the electricity generated by the perovskite solar panel into the energy storage module.

[0026] During actual use of this system, when the vehicle is in normal driving or in windy weather, the overall control system can detect the start of the wind turbine in the wind energy collection module, thereby configuring the circuit to be connected and storing the electrical energy generated by the wind turbine in the energy storage module.

[0027] The system also includes a life cycle analysis module, which includes a detection module, a data collection module, a data analysis module and a feedback module.

[0028] During actual use, the system's lifecycle analysis module monitors and records the entire vehicle in real time, including but not limited to energy consumption and storage, basic vehicle conditions, and damage. This information is analyzed, collected, and stored through the data collection and analysis modules, and feedback is provided through the feedback module. This feedback can be displayed on a display, voice broadcasted, or through other means to inform the driver, raising awareness of comprehensive energy management among drivers and owners. This also facilitates the future development of a large database, the research and development of energy recovery solutions for each unit, and the design of comprehensive energy utilization solutions across the entire vehicle lifecycle and system.

[0029] The present invention also includes a method for independent energy-saving management of heavy-duty trucks, which includes collecting multi-dimensional energy consumption data on the entire vehicle, independent systems, and driving conditions; establishing a database that includes energy sources (diesel / methanol / pure electricity / liquid ammonia, etc.), utilization efficiency, and recovery technology; achieving ≥20% solar energy conversion through roof-mounted perovskite solar panels; using the front wind turbine to recover wind energy during driving, with a conversion efficiency of ≥15%; conducting system durability testing in accordance with the ECE R49 international automotive standard; remotely optimizing energy management strategies through OTA technology; and simultaneously completing the layout design and simulation verification of the energy management system during the new vehicle development phase.

[0030] Based on the combination of this method and system, the present invention can achieve data collection, data integration and calculation of various energy consumption and recovery data, and can further add external energy collection data to the system by collecting conversion data of solar energy, wind energy, etc., which complies with the ECE R49 international automotive standard. Combined with the feedback module in the system, real-time visualization of vehicle energy consumption and energy recovery can be achieved, which can be processed digitally. The above data can be collected and organized as heavy truck driving data for big data analysis.

[0031] The technical solution described in this invention is not limited to heavy-duty trucks. Its unique design concept and structural principles are also applicable to household gasoline vehicles, new energy vehicles, medium-duty gasoline vehicles, and more. In practical application scenarios, this system can be freely combined with system settings and corresponding usage methods based on the characteristics of different vehicles to achieve the optimal usage for various types of vehicles.

[0032] In summary, the application background of this technical solution lies in domestic heavy-duty truck vehicles. China is the world's largest user of heavy-duty trucks, which is in line with China's major strategic development direction of new energy. At present, the core of global heavy-duty trucks is still to improve the energy efficiency of the engine. The energy management of independent systems such as downhill kinetic energy collection, engine improvement, fuel saving, and simple operational efficiency has not formed a systematic management, and energy consumption is not managed from the perspective of the entire vehicle life cycle. The independent energy-saving management system and method proposed in the present invention analyzes and optimizes the design scheme, establishes a large database, develops and establishes energy recovery schemes for each unit, and then designs an energy comprehensive utilization scheme from the perspective of the entire vehicle life cycle and the entire system.

[0033] In future development, due to the high adaptability and easy adjustment of this system itself, which can be attached to existing vehicles, it will be easier to combine it with new materials, so that it can achieve the actual effect of popularization in a shorter period of time.

[0034] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0035] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0036] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is to facilitate the distinction between corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
