When the battery unlock status is "battery unlock successful", the corresponding unlock score is determined to be 1; otherwise, it is 0. If the vehicle fault status is no fault, the corresponding fault score is determined to be 1; otherwise, it is 0. The status score is obtained through the conversion relationship based on the location score, the unlock score, the fault score, and the vehicle priority.

[0009] Optionally, the transformation relationship satisfies: Z = P × W1 + U × W2 + F × W3 + R × W4; Wherein, Z is the status score, P is the location score, U is the unlock score, F is the fault score, R is the vehicle priority, W1 is the status score weight coefficient, W2 is the unlock score weight coefficient, W3 is the fault score weight coefficient, and W4 is the vehicle priority weight coefficient.

[0023] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0024] In related technologies, existing single-channel battery swapping stations only have one independent battery swapping lane, and their operation process strictly follows a fixed sequence of "previous vehicle completes battery swapping - completely leaves the lane - subsequent vehicle enters and is positioned," without any buffer space. Throughout the entire battery swapping process, the time consumption of several key stages is easily affected by uncontrollable factors: Before swapping, the accurate positioning of the vehicle after entering the lane relies on the driver's experience; novice drivers may need to make multiple adjustments to meet the requirements of the battery swapping robot, consuming considerable additional adjustment time; during swapping, if the vehicle has issues such as difficulty unlocking the battery compartment door or poor battery interface contact, the driver needs to get out of the vehicle to investigate and resolve the problem, further extending the operation time; after swapping, the time it takes for the vehicle to leave the lane is entirely determined by the driver's operating rhythm, typically taking 30 seconds to 1 minute from unlocking the parking and starting the vehicle to leaving the lane, and there are uncertainties such as temporary driver stops. The combined time spent in the above-mentioned steps results in the battery swapping equipment at a single-channel battery swapping station being idle for extended periods during vehicle positioning adjustments, fault diagnosis, and waiting for departure. This prevents the equipment from continuously performing its operational functions, ultimately increasing the average battery swapping time per vehicle, reducing battery swapping efficiency, and making it difficult to meet the high-frequency energy replenishment needs of large-scale operations.

[0025] To address the problems existing in the aforementioned related technologies, this invention provides a dual-channel battery swapping system.

[0026] As shown in Figure 1, an embodiment of the present invention provides a dual-channel battery swapping system, including a control room 1, a battery compartment 2, a battery swapping device 3, a first battery swapping channel 4, and a second battery swapping channel 5. The first battery swapping channel 4 is provided between the control room 1 and the battery compartment 2, and the second battery swapping channel 5 is provided at the other end of the battery compartment 2 away from the first battery swapping channel 4. The battery swapping device 3 is mounted above the control room 1, the first battery swapping channel 4, the battery compartment 2, and the second battery swapping channel 5. The control room 1 includes a control module, which is communicatively connected to the battery compartment 2 and the battery swapping device 3, respectively.

[0027] Specifically, the first battery swapping channel 4 is located between the control room 1 and the battery compartment 2, serving as one of the operating channels to handle vehicle battery swapping needs. The second battery swapping channel 5 is located at the other end of the battery compartment 2, away from the first battery swapping channel 4, forming a symmetrical distribution with the first battery swapping channel 4, together constituting a dual-path operating structure, effectively expanding the battery swapping capacity. The battery swapping equipment 3 adopts an overhead installation method, covering the area above the control room 1, the first battery swapping channel 4, the battery compartment 2, and the second battery swapping channel 5. It can flexibly move and switch between the two battery swapping channels, achieving dual-channel operation scheduling without configuring two independent battery swapping equipment 3, significantly reducing equipment costs. The control room 1 integrates a control module, which establishes a communication connection with the battery compartment 2 through a network station control system, acquiring key data such as the state of charge (SOC), temperature, and voltage of the backup battery in real time. At the same time, it interacts with the battery swapping equipment 3, accurately issuing battery swapping commands, path planning commands, and safety control commands, coordinating the entire process of vehicle positioning, battery swapping execution, battery buffering, and replenishment between the two battery swapping channels, ensuring the efficient and orderly progress of the battery swapping process.

[0028] The control module is used to: determine the battery swapping sequence based on the comparison result of the vehicle status of the first vehicle in the first battery swapping channel 4 and the vehicle status of the second vehicle in the second battery swapping channel 5; and control the battery swapping equipment 3 to swap the batteries of the first vehicle and the second vehicle according to the battery swapping sequence.

[0029] Specifically, such as Figure 3 As shown in the diagram, the arrows indicate the vehicle's travel direction. When a vehicle enters the first battery swapping lane 4 and the second battery swapping lane 5 from the main road 8, the control module acquires the real-time vehicle status of the first vehicle in the first battery swapping lane 4 and the second vehicle in the second battery swapping lane 5. This vehicle status includes location information obtained from the vehicle positioning system and 3D vision recognition system, battery unlocking information obtained from the station interaction system, vehicle fault information obtained from vehicle fault diagnosis software, and vehicle priority determined by the vehicle's task type. The specific battery swapping sequence of the first and second vehicles is then determined through a comprehensive comparison of the two vehicle statuses. Based on this sequence, precise control commands are immediately issued to the battery swapping equipment 3 system, including path planning, battery grabbing and installation control, and interaction with the battery compartment 2 for cached battery scheduling commands. This ensures that the battery swapping equipment 3 efficiently and safely completes the battery replacement operation according to the predetermined sequence, achieving automated and intelligent closed-loop control of the battery swapping process.

[0030] In this embodiment, a symmetrical structure is achieved by placing the first battery swapping channel between the control room and the battery compartment, and the second battery swapping channel at the other end of the battery compartment. Combined with battery swapping equipment mounted above each core area, this allows for flexible movement and rapid switching of the battery swapping equipment between the two channels. This eliminates the need for two separate sets of battery swapping equipment, enabling a "parallel preparation + continuous operation" mode. This avoids equipment idleness caused by the traditional single-channel battery swapping station's serial "battery swap-departure-entry" process. Simultaneously, the control module collects and quantitatively compares the vehicle status information in both channels in real time to accurately determine the optimal battery swapping sequence. This ensures that the battery swapping equipment quickly connects to vehicles that have already completed preparation, completely avoiding operational interruptions caused by uncontrollable factors such as vehicle departure delays and preparation time. Furthermore, the two-channel diversion reduces vehicle queuing time, maximizes the utilization of battery swapping equipment and battery resources, significantly improves the battery swapping efficiency of the station, and effectively meets the high-frequency energy replenishment needs of large-scale operations.

[0031] Optionally, determining the battery swapping sequence based on a comparison of the vehicle status of the first vehicle in the first battery swapping channel and the vehicle status of the second vehicle in the second battery swapping channel includes: The corresponding status score is obtained based on the vehicle status through a preset conversion relationship; The battery swapping sequence is obtained by sorting the status scores of the first vehicle and the second vehicle from high to low.

[0032] In this optional embodiment, the complete vehicle status of vehicles in the first and second battery swapping channels is collected. This vehicle status includes the location status reflecting positioning accuracy, the unlocking status reflecting the battery compartment door unlocking status, the fault status representing the operation of the vehicle's core system, and the vehicle priority determined based on the task type. Then, according to a preset multi-dimensional quantization conversion relationship, the above-mentioned dispersed vehicle status indicators are quantified into corresponding scores, i.e., the status scores of the first and second vehicles respectively. Finally, the status scores of the two vehicles are sorted in descending order of value, and the vehicle with the higher score is listed as the priority battery swapping object. Based on this, a clear battery swapping order is generated to ensure that battery swapping resources are tilted towards vehicles that are better prepared and have more urgent needs, which is in line with the core goal of improving the operation efficiency of the dual-channel battery swapping station.

[0033] Optionally, the vehicle status includes vehicle location status, battery unlock status, vehicle malfunction status, and vehicle priority; obtaining the corresponding status score based on the vehicle status through a preset conversion relationship includes: If the vehicle's position status meets the preset position requirements, the corresponding position score is determined to be 1; otherwise, it is 0. When the battery unlock status is "battery unlock successful", the corresponding unlock score is determined to be 1; otherwise, it is 0. If the vehicle fault status is no fault, the corresponding fault score is determined to be 1; otherwise, it is 0. The status score is obtained through the conversion relationship based on the location score, the unlock score, the fault score, and the vehicle priority.

[0034] Optionally, the transformation relationship satisfies: Z = P × W1 + U × W2 + F × W3 + R × W4; Wherein, Z is the status score, P is the location score, U is the unlock score, F is the fault score, R is the vehicle priority, W1 is the status score weight coefficient, W2 is the unlock score weight coefficient, W3 is the fault score weight coefficient, and W4 is the vehicle priority weight coefficient.

[0035] In this optional embodiment, a binary quantization method is used to score the vehicle location status, battery unlock status, and vehicle fault status. Specifically, when the vehicle location status meets the preset positioning requirements for battery swapping (i.e., positioning deviation ≤ ±5cm, meeting the precise docking requirements of the battery swapping robot), the corresponding location score is determined to be 1. If the positioning deviation exceeds the preset range, preventing the battery swapping docking requirements from being met, the location score is 0. When the battery unlock status is that the battery swapping station's interactive system successfully receives the door unlock signal and the door is in an openable state, the corresponding unlock score is determined to be 1. If the door is not unlocked, is unlocking in progress, or has failed to unlock, preventing the battery swapping operation, the unlock score is 0. When the vehicle fault status is that the vehicle's core system... When there are no fault alarms, no leakage, high temperature or other safety hazards, the corresponding fault score is determined to be 1. If there is a fault alarm in the core component or a fault in a secondary component that affects the safety of battery swapping, the fault score is 0. After completing the above three binary scores, the vehicle priority is combined with the pre-quantified vehicle priority. For example, the vehicle priority is divided into four levels according to the urgency of the battery swapping demand and assigned a corresponding quantitative score. Among them, heavy trucks performing emergency tasks to transport disaster relief materials are level one priority with a quantitative score of 100 points; ordinary operating logistics heavy trucks are level two priority with a quantitative score of 80 points; non-operating self-use engineering vehicles are level three priority with a quantitative score of 60 points; and vehicles that voluntarily swap batteries during off-peak hours or only require battery maintenance are level four priority with a quantitative score of 40 points. By using a pre-defined multi-dimensional weighted conversion relationship (i.e., status score = location score × W1 + unlock score × W2 + fault score × W3 + vehicle priority score × W4, where W1, W2, W3, and W4 are the pre-defined weights of location score, unlock score, fault score, and vehicle priority, respectively, and W1 + W2 + W3 + W4 = 1), the quantitative results of location score, unlock score, fault score, and vehicle priority are weighted and calculated to obtain the corresponding vehicle status score. This score can intuitively reflect the completeness of the vehicle's ability to meet the conditions for battery swapping operations and the urgency of the battery swapping demand, providing a quantitative basis for the accurate determination of the battery swapping sequence.

[0036] Optionally, the system also includes: When the status score of the first vehicle and the status score of the second vehicle are equal, the battery swapping sequence is set to perform the battery swapping operation on the first vehicle first, and then perform the battery swapping operation on the second vehicle.

[0037] In this optional embodiment, when the status scores calculated by the first vehicle waiting to be swapped in the first battery swapping channel and the second vehicle waiting to be swapped in the second battery swapping channel are equal according to a preset conversion relationship, in order to ensure the orderliness and determinism of the dual battery swapping channel operation scheduling and avoid operation delays or logical confusion caused by consistent scores, the battery swapping sequence is explicitly set as follows: the battery swapping operation is performed on the first vehicle in the first battery swapping channel first, and after the battery swapping of the first vehicle is completed, the battery swapping equipment is controlled to perform battery swapping operation on the second vehicle. This setting fits the layout architecture and overall scheduling logic of the dual-channel battery swapping station, and can quickly determine the operation sequence without introducing additional complex decision factors. It not only ensures the efficient connection of the battery swapping process, but also improves battery swapping efficiency, alleviates queuing congestion, and simplifies the scheduling algorithm of the control system, ensuring that the technical solution has strong executability.

[0038] Optionally, such as Figure 1 The battery compartment 2 includes a battery housing 21, a buffer position 22, and a carrier module 23. Multiple battery housings 21 are arranged sequentially along the length of the battery compartment 2. The battery housing 21 near the first battery swapping channel 4 is used to set the buffer position 22, and / or the battery housing 21 near the second battery swapping channel 5 is used to set the buffer position 22. The other battery housings 21 are used to set the carrier module 23.

[0039] In this optional embodiment, the battery compartment 2 adopts a modular layout design along its length to adapt to the high-efficiency battery transfer requirements of the dual-channel battery swapping system. Internally, it includes battery housings 21, buffer bays 22, and a rack-mounting module 23. Multiple battery housings 21 are arranged sequentially along the length of the battery compartment 2, forming a continuous battery storage and operating space. The number of battery housings 21 can be flexibly adapted according to the actual needs of the battery swapping station, such as site size, average daily swapping current, and investment costs. Figure 4As shown, A is a dual-channel layout with 8 battery boxes 21 (4 columns of battery boxes 21 are arranged along the length of battery compartment 2 and 2 rows are arranged along the width, forming a 4×2 array layout), which is suitable for small and medium-sized battery swapping stations or scenarios with low battery swapping demand. B is a dual-channel layout with 10 battery boxes 21 (5 columns of battery boxes 21 are arranged along the length of battery compartment 2 and 2 rows are arranged along the width, forming a 5×2 array layout), which is suitable for medium-sized battery swapping stations. C is a dual-channel layout with 12 battery boxes 21 (6 columns of battery boxes 21 are arranged along the length of battery compartment 2 and 2 rows are arranged along the width, forming a 6×2 array layout), which is suitable for large-scale battery swapping stations. All different specifications adopt the core architecture of "single battery swapping device 3 + dual battery swapping channels + partitioned battery compartment 2". By simply adjusting the number of battery boxes 21 to adapt to different battery swapping capacity requirements, the technical effect of dual-channel parallel preparation and continuous battery swapping can be achieved, effectively improving battery swapping efficiency. Among them, the battery box 21 near the first battery swapping channel 4 is specifically used to set up the buffer position 22, and / or the battery box 21 near the second battery swapping channel 5 is also used to set up the buffer position 22. The buffer position 22 can temporarily store a fully charged spare battery or a depleted battery that has just been replaced from the vehicle, so as to realize the battery's nearby storage and quick docking, and reduce the movement distance of the battery swapping equipment 3. The remaining battery boxes 21 located in the middle area are uniformly used to set up the rack module 23. This module integrates the battery charging unit 232, storage rack and transfer mechanism. It not only undertakes the charging and maintenance function of depleted batteries, but also serves as the core battery storage unit 231. Together with the buffer position 22, it realizes the cyclic replenishment and efficient scheduling of batteries. This ensures the independence and timeliness of battery replenishment in the two battery swapping channels, maximizes the use of the battery compartment 2 space, improves battery turnover efficiency, and provides stable battery resource support for parallel battery swapping in both channels.

[0040] Optionally, such as Figure 1 and Figure 2 As shown, the chassis 23 includes a battery storage unit 231, a charging unit 232, and a dual-channel charging gun 233. The battery storage unit 231 is used to store the battery, the charging unit 232 is used to charge the battery in the battery storage unit 231, and the dual-channel charging gun 233 is used to charge vehicles outside the station.

[0041] In this optional embodiment, the chassis 23 serves as a core component of the heavy-duty truck battery swapping system, integrating battery storage, in-station charging, and off-site energy replenishment functions. Its structural design and functional configuration are highly adaptable to diverse energy replenishment needs. Specifically, it includes three core parts: a battery storage unit 231, a charging unit 232, and dual-channel charging guns 233. The battery storage unit 231 is equipped with a dedicated storage frame, guiding and limiting devices, and an on-site sensor, providing a safe and stable storage space for depleted and fully charged batteries. Simultaneously, the sensor monitors the battery's location in real time, ensuring the standardization and traceability of battery storage. The charging unit 232 adopts a modular design, composed of multiple power modules connected in parallel, and possesses intelligent functions such as automatic charging, power metering, and fault alarms. Based on the battery status and health parameters of the batteries in the battery storage unit 231, the system can automatically match the charging strategy to provide efficient and safe charging services for the stored batteries, ensuring that the batteries can quickly return to full charge. The dual-channel charging gun 233, as an extended energy replenishment interface, breaks through the limitation that the battery swapping station can only serve vehicles swapping within the station. It is specifically designed to provide flexible energy replenishment for vehicles with charging needs outside the station. It supports multiple charging modes such as charging one vehicle with a single gun, charging one vehicle with both guns simultaneously, or charging two vehicles separately with both guns. It is also interlocked with the battery charging function within the station to avoid circuit conflicts. This not only improves the utilization rate of the chassis 23, but also expands the service scenarios of the battery swapping station. It allows the battery swapping station to meet the core needs of heavy truck battery swapping while also taking into account temporary charging needs, thus enhancing the practicality and flexibility of the system.

[0042] Optionally, such as Figure 1 As shown, the system also includes a first channel box 6 and a second channel box (7). The first channel box 6 is located above the first battery swapping channel 4, and the second channel box 7 is located above the second battery swapping channel 5. The control room 1, the first channel box 6, the plurality of battery boxes 21 and the second channel box 7 are sequentially connected and interconnected. The battery swapping track of the battery swapping device 3 is located in the channel formed by the control room 1, the first channel box 6, the plurality of battery boxes 21 and the second channel box 7.

[0043] In this optional embodiment, the first channel box 6 is erected above the first battery swapping channel 4, and the second channel box 7 is erected above the second battery swapping channel 5, forming a spatial layout corresponding vertically to the battery swapping channels. The control room 1, the first channel box 6, multiple battery boxes 21, and the second channel box 7 are connected sequentially according to functional logic and are internally interconnected, together forming a continuous operating channel for the battery swapping equipment 3. The battery swapping track of the battery swapping equipment 3 is laid along the entire connected channel, covering the entire operating range of the control room 1, the first battery swapping channel 4, the battery compartment 2, and the second battery swapping channel 5, so that the battery swapping equipment 3 can move flexibly and switch seamlessly between functional areas by relying on the track, and can achieve efficient battery swapping for vehicles in the dual battery swapping channels without configuring two independent battery swapping equipment.

[0044] Optionally, the system also includes a fire protection subsystem, which includes fire detectors, manual fire alarm buttons, fire audible and visual alarm buttons, and a fire central controller. The fire detectors and manual fire alarm buttons are respectively installed in preset locations in the control room and the battery compartment. The fire central controller is installed in the control room and is communicatively connected to the fire detectors and the manual fire alarm buttons.

[0045] In this optional embodiment, the system also includes a fire protection subsystem that provides comprehensive protection for battery swapping safety. Its core consists of fire detectors, manual fire alarm buttons, fire alarm audible and visual alarms, and a centralized fire controller. These components, through scientific layout and coordinated operation, construct a complete fire protection system of "automatic monitoring - manual triggering - centralized control - audible and visual warning." The fire detectors and manual fire alarm buttons are precisely deployed in preset locations in key areas such as the control room and battery compartment. The fire detectors can detect early warning signals of fire, such as smoke concentration and temperature anomalies, in real time, achieving automatic early warning of fires. The manual fire alarm buttons are convenient for personnel to use. Upon discovering a fire, personnel can proactively trigger the alarm immediately, forming a dual guarantee of automatic monitoring and manual triggering. The fire control center, as the core control hub of the fire protection subsystem, is centrally located in the control room. It establishes connections with fire detectors and manual fire alarm buttons in various areas through a stable communication link. It can receive various alarm signals in real time and analyze and judge the signals. Once a fire is confirmed, it can immediately activate the fire alarm to emit a strong audible and visual warning signal, reminding on-site personnel to take timely evacuation. At the same time, it provides a control basis for subsequent activation of fire extinguishers and other fire-fighting equipment and precise handling of the fire, comprehensively protecting the safety of the battery swapping station, personnel, and vehicles.

[0046] Optionally, the system further includes a station interaction subsystem, which is used for: Based on a preset state matching rule, the indicator light color corresponding to the first battery swapping channel is displayed according to the channel status of the first battery swapping channel, and the indicator light color corresponding to the second battery swapping channel is displayed according to the channel status of the second battery swapping channel. The state matching rule includes a one-to-one correspondence between the channel status and the indicator light color. And / or, through a loudspeaker announcement system.

[0047] In this optional embodiment, the system also includes a station interaction subsystem adapted to the operational needs of dual battery swapping channels. Its core function is to provide intuitive and efficient information interaction and operational guidance for heavy-duty truck drivers waiting for battery swapping and station control and maintenance personnel. On the one hand, the subsystem strictly follows the preset state matching rules (which clearly define the one-to-one correspondence between various operating states of the battery swapping channel and indicator light colors, such as green when the channel is free and can be entered, yellow when battery swapping is in progress, red when equipment malfunctions and service is suspended, and blue when the vehicle is ready for battery swapping). It collects the dynamic channel status (covering free, battery swapping in progress) of the first and second battery swapping channels in real time. The system can simultaneously control the indicator lights of the corresponding lanes to display matching colors, allowing drivers to quickly determine lane availability without having to get out of their vehicles to check, and accurately select an available lane, reducing vehicle hesitation and adjustment time. On the other hand, the subsystem can simultaneously broadcast system prompts via integrated speakers, including lane status information (e.g., the first battery swapping lane is available, please enter in an orderly manner), battery swapping process guidance (e.g., the vehicle has been positioned and battery swapping is about to start, please fasten your seatbelt), and fault warnings (e.g., if the second battery swapping lane is temporarily out of service, it is recommended to choose the first battery swapping lane), further enhancing the timeliness and accuracy of information transmission. Through the coordinated interaction of visual indicator lights and voice broadcasts, the station's interactive subsystem effectively improves the vehicle dispatching efficiency of dual battery swapping lanes, reduces queuing congestion caused by information asymmetry, and provides convenient human-machine interaction support for the efficient operation of battery swapping stations in land-constrained scenarios such as highway service areas and gas stations along main roads, helping the dual-lane battery swapping mode achieve better operational efficiency.
