[0047] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0048] Combine the following Figure 1 A vehicle battery replacement system according to some embodiments of the present application is described.

[0049] The present application provides a vehicle battery replacement system, such as Figure 1 As shown, it includes: a data acquisition module 1, an intelligent scheduling module 2, a battery replacement control module 3 and a power battery 4;

[0050] In the specific working process, the data acquisition module 1 is used to obtain the operating status of the vehicle and the battery swap station;

[0051] In the specific working process, the intelligent scheduling module 2 is used to predict the battery replacement sequence and queue situation of the vehicle according to the operating status, and schedule the vehicle and the power battery 4;

[0052] In the specific working process, the battery replacement control module 3 is used to control the flexible lifting equipment in sections to move the power battery 4 to replace the battery of the vehicle, wherein the flexible lifting equipment includes a steel wire rope and a spring shock-absorbing plug interface.

[0053] In some examples, the lifting equipment with "wire rope and spring shock absorber" is integrated with intelligent image recognition technology to form a flexible lifting battery replacement technology. Flexible lifting battery replacement technology is used to clamp, lift, and place the battery pack, and the spring shock-absorbing plug interface is used to improve the safety of the battery pack. Through refined segmented control, the swaying of the wire rope during the rising and falling process is eliminated, and the alignment accuracy of the connector is improved. Combined with the multi-stage spring assembly and three-stage positioning technology of the connector, the vibration and impact caused to the interface are reduced, and the damage to the structural material caused by mechanical collision during the battery replacement process is eliminated, so that the equipment can achieve zero failure and significantly improve production efficiency. Figure 2 The results of the on-site vibration test show that compared with equipment that does not use this technology, the impact forces on the X, Y, and Z axes are reduced by 42%, 70%, and 26%, respectively.

[0054] In the embodiment of the present application, based on the green energy storage charging and swapping technology system and mobile battery swapping technology, a new battery swapping mode of "centralized charging-mobile battery swapping" is proposed, which realizes the upgrade of battery swapping mining trucks from centralized battery swapping at fixed points to full coverage battery swapping at flexible points, greatly improving the overall operating efficiency of new energy equipment in mining areas and greatly broadening the scope of application, such as Figures 3 to 5 As shown. The invented mobile battery swap technology has the advantages of no need for external power supply, no need for infrastructure construction, fast station landing, low construction / operation and maintenance costs and high reuse rate. It can be built in complex terrains such as urban roads and mines to meet the charging and swapping needs of mining trucks and heavy construction equipment. In conjunction with fixed battery swap stations, it can achieve full coverage of various vehicle types such as new energy mining trucks, new energy heavy trucks, as well as various application scenarios such as field mining areas, large-scale infrastructure, and land and water ports. The spatial separation of charging and battery swapping makes it possible to use low-cost pit-mouth thermal power or new energy abandoned power nearby.

[0055] In view of this, this embodiment provides a vehicle battery replacement system, which obtains the operating status of the vehicle and the battery replacement station through the data acquisition module; uses the intelligent scheduling module to predict the battery replacement sequence and queue of the vehicle according to the operating status, and dispatches the vehicle and power battery; uses the battery replacement control module to control the flexible lifting equipment to move the power battery to replace the vehicle in sections, thereby improving the reliability of battery replacement. In terms of power utilization, the battery replacement station is equipped with an energy storage inverter to replace the traditional charger to charge the battery, so that the battery has the ability to feed power, and the battery replacement station can participate in the application and operation of the microgrid. From the perspective of environmental adaptability, by combining the battery replacement battery pack technology, the movable function and the integrated pantograph charging technology, it is possible to replace the battery for the vehicle without an external power supply or infrastructure land.

[0056] In some examples, the battery replacement control module 3 includes: a battery energy storage unit 31;

[0057] In a specific working process, the battery energy storage unit 31 is used to centrally charge one or more power batteries 4 on the battery transport vehicle through an energy storage inverter.

[0058] For example, the power conversion system (PCS) energy storage module replaces the traditional charging module to charge the battery, so that the battery has the ability to feed power and has the function of an energy storage power station. The station control system of the power swap station with an energy management system (EMS) can receive grid dispatch in real time and provide direct support to the grid. For example, the photovoltaic + power swap mining truck integrated rooftop distributed photovoltaic (5.8MW) demonstration project has been connected to the grid using the "power swap-energy storage station" model, and its overall electrical efficiency can reach 88.5%.

[0059] In some examples, the power battery 4 includes: a special-shaped liquid cooling unit 41, a flattened high-voltage box 42, a foldable locking mechanism 43, a variable-angle connector 44, a retractable battery replacement positioning device 45 and a battery management unit 46.

[0060] For example, the internal space of the power battery system is optimized and the safety of the battery system is ensured through technologies such as special-shaped liquid cooling units, flat high-voltage boxes, foldable locking mechanisms, variable-angle connectors, and retractable battery replacement positioning systems. The power battery system components that integrate the above technologies are combined with the compressed arrangement of the electrical wiring harness inside the battery to reduce the internal invalid space and greatly improve the volume energy density of the battery replacement system. Figure 6 As shown. By increasing the fixed torque, the safety of the power battery system is improved, and it can withstand 5g acceleration in three directions, ensuring the structural strength and toughness of the battery system and increasing the battery life.

[0061] In the embodiment of the present application, the automatic charging technology of the integrated pantograph is also adopted, and the battery centralized management unit is used to realize the large-scale centralized charging and large-scale energy storage of the mining truck battery. The pantograph charging method of the centralized charging system can realize 1000A charging and 1C fast charging of 540kWh battery. Multiple pantographs automatically charge multiple battery packs on the battery transporter at the same time, with a maximum power of up to 2.5MW. Combined with the intelligent cloud platform technology, the battery is optimized and dispatched, which is advanced and innovative in improving system efficiency.

[0062] In some examples, the battery management unit 46 includes: a decentralized control unit 461 and a thermal management unit 462;

[0063] In the specific working process, the distributed control unit 461 is used to adjust the working mode of each battery cluster;

[0064] The thermal management unit 462 is used to manage the shape of the internal flow channel of the liquid cooling plate and the layout of the liquid cooling pipeline.

[0065] For example, through distributed control technology and efficient thermal management technology, stable and controllable charging and uniform heat dissipation between battery clusters are achieved, making the power battery system safer, more reliable and more efficient in charging and discharging. The distributed control technology for energy storage systems is transplanted to the power battery system, which avoids the mismatch problem of battery cluster parallel connection at the physical level and solves the safety risks caused by the inter-cluster circulation in the power battery system. Each battery cluster can operate in the optimal input / output power state. By using efficient thermal management technology, the flow field of the liquid cooling plate and the design of the liquid cooling pipeline are optimized, which greatly reduces the laminar drag effect of the coolant when the channel turns, making the spatial distribution of the coolant flow more uniform, the heat dissipation consistency of the battery cells better, and the temperature difference of the battery cells less than 3°C.

[0066] The embodiments of the present application use optimized layout, decentralized control technology and efficient thermal management technology to improve the volume energy density, life and stability of the battery system. Battery packs adapted to different vehicle models and battery swap stations have been introduced. By adjusting the spatial layout of the battery box, the internal space utilization rate is explored. By applying energy storage decentralized control technology, virtual parallel connection between battery clusters is achieved to ensure that the battery string is always in the best operating state. The use of efficient thermal management technology ensures a more balanced flow distribution of the coolant, improves the consistency of heat dissipation of the battery cells, and improves the service life and stability of the battery system.

[0067] In some examples, the system further includes: a communication module 5;

[0068] The communication module 5 is connected to the data acquisition module 1, the intelligent scheduling module 2 and the battery replacement control module 3 respectively;

[0069] In the specific working process, the communication module 5 is used to control the data communication between the data acquisition module 1, the intelligent scheduling module 2, the battery replacement control module 3 and the data management cloud platform.

[0070] In the embodiment of the present application, a bidirectionally compatible battery system integration standardized design tool is used to define the standard communication protocol of the Qingneng Institute's battery swap mining card, the mechanical structure matching interface between the battery pack-vehicle and the battery pack-battery swap station. In terms of communication, the battery swap controller is used as a "grasp" to formulate the data communication protocol between the data acquisition module, the intelligent scheduling module, the battery swap control module and the data management cloud platform in the vehicle communication ring network to control the vehicle-battery pack communication interface; the communication protocol between the battery swap station control system, the battery pack battery swap locking system and the automatic charging system is formulated to control the battery pack / charging and swapping station communication interface; the business and technical unbundling between the battery cell, the battery factory, the vehicle factory, and the charging and swapping OEM factory is realized. In terms of structure, the installation position and envelope size of the battery swap connector, the positioning and locking mechanism are unified to realize the non-differential installation of different types of battery packs on different models; a universal battery system battery swap top is designed, which can adapt to different grabbing methods of different battery swap accessory manufacturers to achieve compatibility of one pack with multiple stations. Through the above standardized definition, the compatibility adaptation between various types of battery packs and multiple models and multiple battery swap stations is completed.

[0071] Compared with the current existing technology, the dual-mode battery replacement and energy replenishment system of fixed battery replacement stations and mobile battery replacement stations in this embodiment can adapt to more battery replacement scenarios. As shown in Table 1, in terms of battery adaptability, the backpack battery pack and top-hanging battery replacement mode are compatible with the backpack battery pack and side battery replacement mode, and the maximum lifting weight can reach 8t; in terms of scene adaptability, it can be used in places with good road conditions and power supply and in environments with complex road conditions and difficult power supply, and can take into account closed roads and highways. Heavy trucks that can replace batteries. Compared with the mobile battery replacement vehicles launched by Guodian, the assembled steel structure roadbed foundation adopted by the Qingneng Institute's plan can be directly carried out on any ground, while the Guodian Investment plan can only be carried out on cement ground and cannot directly carry out business operations; compared with the vehicle-mounted mobile battery replacement station, in addition to having the advantages of the assembled steel structure roadbed foundation relative to Guodian Investment, the maximum weight of the battery replacement battery pack that can be supported also has an advantage. In terms of intelligent scheduling and data management, compared with the existing technical solutions, this solution adds scheduling algorithm optimization for battery swap station clusters, and makes estimates based on battery system data to achieve functions such as battery health monitoring, fault warning and scheduling support.

[0073]

[0074] Compared with the current existing technology, this embodiment provides a vehicle battery replacement system, which can reasonably arrange the battery replacement sequence by predicting the battery replacement demand and queuing situation of the vehicle to avoid long waiting time of the vehicle. According to the operating status of the vehicle and the battery replacement station, the battery replacement process can be dynamically adjusted to ensure a smooth and efficient battery replacement process. The battery replacement efficiency is high and the waiting time is short. Through the intelligent battery replacement scheduling method, the reliability and stability of the battery replacement service are improved. It is also possible to reasonably arrange the charging and scheduling of the battery according to the battery replacement demand of the vehicle and the battery inventory of the battery replacement station to avoid battery idleness or excessive use, optimize the operation process of the battery replacement station, and improve the overall operation efficiency of the battery replacement station.

[0075] In order to improve the current technical problem that mining trucks have low efficiency in queuing for battery replacement, and thus cannot be put into transportation tasks in time, affecting operational efficiency. This embodiment provides a vehicle battery replacement method, such as Figure 7 As shown, the method includes:

[0076] Step 201: Obtain the operating status of the vehicle and the battery swap station.

[0077] In some examples, the three technologies of high-frequency sampling, data compression, and data stream processing of on-board mobile terminals are innovatively applied to the battery-swap heavy-duty truck scenario, laying a solid foundation for various data-based functions. First, in order to support functions such as battery fault prediction, health diagnosis, and intelligent scheduling, this project innovatively adopts a high-frequency data acquisition mode. From acquisition, transmission to storage and analysis, the finest granularity of the entire data link can reach 10 milliseconds. Secondly, the project uses high-frequency sampling technology in data acquisition; data compression technology is used in transmission and storage to ensure accuracy while ensuring granularity and transmission efficiency. Finally, in terms of data analysis, massive data stream processing technology is used to simultaneously complete data cleaning and monitoring, and respond to data anomalies in a timely manner. It provides strong data support for battery fault prediction, health diagnosis, and intelligent scheduling.

[0078] For example, by obtaining the operating status of the vehicle, such as battery power, vehicle location, driving speed, estimated time of arrival at the battery swap station, etc., the operating status of the vehicle can be monitored in real time. By obtaining the operating status of the battery swap station, such as the health of the battery swap equipment, battery inventory, charging facilities, the number of queued vehicles, etc., the normal operation of the battery swap station equipment can be ensured.

[0079] Step 202: predict the battery replacement sequence and queue status of the vehicles based on the operating status.

[0080] In some examples, a queuing prediction model can be established based on the vehicle's operating status data, combined with the operating status data of the battery swap station and the battery swap demand forecast results, to predict the queuing situation at the battery swap station in the future, where the queuing situation can include the number of queued vehicles, the expected waiting time, etc. The prediction of the battery swap sequence needs to take into account multiple factors, such as the priority of the vehicle, the time urgency of the battery swap demand, and the battery inventory of the battery swap station.

[0081] Step 203: Based on the battery replacement sequence and queuing status of the vehicles, dispatch the vehicles and power batteries for battery replacement.

[0082] In some examples, the system is intervened through a clustered top-level intelligent scheduling algorithm that integrates electric heavy trucks, battery pack transfer vehicles, battery swap stations, and charging stations. Based on data such as the remaining power of the heavy truck fleet, the occupancy of the battery swap station, and the stock of spare batteries, the system rationalizes the scheduling of vehicles for battery swapping, reduces the investment in spare batteries and battery swap stations, and improves vehicle operating efficiency.

[0083] For example, the intelligent scheduling of large-scale battery swapping vehicles and battery swapping stations can improve the efficiency of battery swapping in closed scenarios, which is particularly effective for large-scale engineering operation scenarios such as organized mines. Compared with free battery swapping, different scheduling strategies make obvious differences in overall operating efficiency, which is where the advantages and disadvantages of scheduling are reflected. Top-level scheduling represented by team scheduling can improve work efficiency by about 20% compared to single-vehicle scheduling while keeping the number of equipment deployed unchanged.

[0084] For example, the operating status of vehicles, battery swap stations and other equipment is predicted, and the possible battery swap sequence and queue situation in the next 12 hours are predicted through artificial neural networks, and the battery pack deployment is automatically dispatched based on this, which is a supplement to the top-level dispatch of the above-mentioned mining truck end. The cloud platform then directly sends the dispatch instructions to the driver's terminal, making the whole process automated and intelligent, and the global dispatch optimized.

[0085] In the embodiment of the present application, vehicles travel in a relatively small enclosed area with high traffic density, fixed routes and high predictability, which facilitates centralized management and provides convenience for unified digital and intelligent control and dispatch; the property rights of equipment assets are centralized, and the operability of retired batteries is high; compared with heavy trucks on the road, intelligent management can bring greater added value. In addition, the proportion of spare battery packs in the battery swap station is higher, and the battery packs with more and larger single-cell capacity are combined with a more uniform and predictable battery swap operation method, which creates more convenient conditions for the battery swap station to participate in "V2G" and provide grid auxiliary services.

[0086] Optionally, the method of this embodiment may further include: analyzing the health status of the vehicle battery by monitoring the real-time status and historical data of the vehicle battery.

[0087] In some examples, faults can be predicted and battery health status diagnosed based on massive historical data, and algorithms can be continuously optimized with the goal of maximizing the value of the battery over its entire life cycle, including battery traceability management and battery pack optimization control strategies.

[0088] For example, based on real-time status and historical data, combined with fault pre-diagnosis technology that has been verified in energy storage power station projects, the health status of the battery can be monitored and analyzed in real time to eliminate hidden dangers. When the vehicle is close to running out of power or an abnormality occurs, the system can issue an early warning in time to prevent the vehicle from breaking down or causing a safety accident due to insufficient power.

[0089] In some examples, by analyzing the failure mechanism of internal short circuits in the battery cells, a high-accuracy AI internal short circuit detection algorithm is developed to achieve real-time and rapid fault warning of gradual internal short circuits. Figure 8As shown, corrections can be made under various conditions to estimate the health status of single cells. Combined with thermal runaway feature monitoring technology and advanced firefighting technology, a multi-level comprehensive safety protection mechanism for battery energy storage systems is constructed to greatly improve the safety of battery energy storage systems. At the same time, data collection and analysis throughout the life cycle also provides a basis for battery recycling.

[0090] For example, the open circuit voltage of the battery is first measured, and then the remaining capacity of the battery is estimated using the ampere-hour integration method. During this process, the system will perform a variety of state corrections to improve the accuracy of the estimation. These corrections may include temperature compensation, aging effects, and other factors. The activation state of the battery can also be captured, that is, the behavioral characteristics of the battery under specific conditions. Similarly, the behavior of the battery in a static state can also be captured to facilitate understanding of the battery's performance under different conditions. Through high-precision and high-stability battery basic parameter detection, the system is able to achieve high-precision and high-stability detection of battery basic parameters. Based on the collected data, the system uses a self-learning battery model algorithm for more in-depth analysis. The multi-objective comprehensive evaluation system then conducts a comprehensive evaluation of the various characteristics of the battery and generates a comprehensive report. Based on the results of all the above processing steps, key parameters such as the battery's state of charge (SOC) and state of health (SOH) can eventually be output.

[0091] Furthermore, the system can also have adaptive capabilities, automatically adjusting its algorithms and methods according to different battery types, operating conditions, environments and other relevant parameters to better serve practical applications. This adaptive capability enables the system to maintain high performance and accuracy in a constantly changing operating environment.

[0092] Compared with the current existing technology, this embodiment first obtains the operating status of the vehicle and the battery swap station, and then predicts the battery swap sequence and queue situation of the vehicle based on the operating status, and then dispatches the vehicle and power battery for battery swap based on the battery swap sequence and queue situation of the vehicle. By predicting the battery swap demand and queue situation of the vehicle, the battery swap sequence can be reasonably arranged to avoid long waiting times for the vehicle. According to the operating status of the vehicle and the battery swap station, the battery swap process can be dynamically adjusted to ensure a smooth and efficient battery swap process. The battery swap efficiency is high and the waiting time is short. Through the intelligent battery swap scheduling method, the reliability and stability of the battery swap service are improved. It is also possible to reasonably arrange the charging and scheduling of the battery according to the battery swap demand of the vehicle and the battery inventory of the battery swap station to avoid battery idleness or excessive use, optimize the operation process of the battery swap station, and improve the overall operation efficiency of the battery swap station.

[0093] Further, as Figure 7 The specific implementation of the method shown in this embodiment provides a vehicle battery replacement device, such as Fig. 9As shown, the device includes: an acquisition module 31, a prediction module 32, and a scheduling module 33.

[0094] The acquisition module 31 is configured as an acquisition module, configured to acquire the operating status of the vehicle and the battery swap station;

[0095] A prediction module 32, configured to predict a battery replacement sequence and a queue situation of the vehicle according to the operating state;

[0096] The scheduling module 33 is configured to schedule the vehicle and the power battery to perform battery replacement based on the battery replacement sequence and queue status of the vehicle.

[0097] In some examples of this embodiment, the acquisition module 31 is further configured to analyze the health status of the vehicle battery by monitoring the real-time status and historical data of the vehicle battery.

[0098] It should be noted that for other corresponding descriptions of the functional units involved in the vehicle battery replacement method provided in this embodiment, please refer to Figure 7 The corresponding description in will not be repeated here.
