Description

Technical Field

[0001] This application relates to the field of new energy storage and lighting equipment maintenance technology, and in particular to an intelligent energy storage and rapid maintenance system for wind-solar integrated streetlights. Background Technology

[0002] Solar-wind integrated streetlights, as green lighting facilities powered by solar and wind energy, typically rely on their own batteries for energy storage. Existing technologies for this type of streetlight energy storage systems suffer from two major technical problems: First, low energy utilization. When the battery is fully charged, the redundant energy generated by the solar and wind power generation devices cannot be effectively utilized and is wasted. Prolonged overcharging also severely shortens the battery's cycle life. Second, poor maintenance convenience. The battery compartment usually uses a fixed encapsulation design. When batteries age or are damaged and require repair or replacement, maintenance personnel need to carry specialized tools to disassemble the casing, disconnect and reconnect multiple cables, resulting in cumbersome operations that are time-consuming, labor-intensive, and pose safety risks due to potential misoperation. Therefore, how to achieve the coordinated utilization of redundant energy and simplify the battery maintenance process is a pressing technical problem to be solved in this field. Summary of the Invention

[0003] The purpose of this application is to provide an intelligent energy storage and rapid maintenance system for integrated wind and solar streetlights, so as to solve the technical problems of redundant energy waste and cumbersome battery maintenance in the prior art.

[0004] Firstly, this application provides an intelligent energy storage and rapid maintenance system for integrated wind and solar streetlights, comprising: an intelligent docking base fixed to a light pole; the intelligent docking base having a guide mechanism for guiding the insertion of a pluggable intelligent battery module, a locking mechanism for physically locking the pluggable intelligent battery module after it is inserted into place, and a docking connector for establishing an electrical connection with the pluggable intelligent battery module; and the pluggable intelligent battery module, adapted to the structure of the intelligent docking base, for insertion into the intelligent docking base under the guidance of the guide mechanism and locked by the locking mechanism, so as to establish an electrical connection with the intelligent docking base through the docking connector. This technical solution, by designing the battery module and the light pole base as a standardized pluggable structure, simplifies complex maintenance operations into a single physical action, greatly improving maintenance efficiency.

[0005] Optionally, the intelligent docking base further includes a control unit; the control unit is used to control the intelligent docking base to transfer redundant electrical energy in the pluggable intelligent battery module to an external energy storage device through an external energy storage interface when the power state of the pluggable intelligent battery module meets a preset energy transfer trigger condition. This technical solution solves the problem of wasted redundant electrical energy and realizes the synergistic utilization of energy.

[0006] Optionally, the power transfer triggering condition includes: the charging state parameters of the pluggable smart battery module continuously satisfying a float charge state characteristic within a preset duration; the control unit is further configured to, during the redundant power transfer process, when the power level of the pluggable smart battery module is detected to drop to a preset transfer termination threshold, control the smart docking base to disconnect the power transmission from the external energy storage device. This technical solution ensures the accuracy of power transfer decisions and the health status of the battery.

[0007] Optionally, the intelligent docking base further includes a control unit; the control unit is configured to, upon receiving a maintenance replacement command, control the locking mechanism to release the physical lock on the pluggable intelligent battery module, allowing the pluggable intelligent battery module to be removed; the control unit is also configured to, upon detecting that a new pluggable intelligent battery module has been inserted into place, control the locking mechanism to physically lock the new pluggable intelligent battery module. This technical solution achieves automated control of the maintenance process.

[0008] Optionally, before controlling the locking mechanism to release the physical lock, the control unit is also configured to first control the power contacts of the mating connector to disconnect the electrical connection, thereby achieving zero-power insertion and removal. This technical solution improves the safety of live operation.

[0009] Optionally, the guiding mechanism is a V-shaped self-aligning precision guide rail. The structure of the V-shaped self-aligning precision guide rail is used to provide lateral self-aligning force during the insertion of the pluggable smart battery module to correct insertion deviation. This technical solution ensures the accuracy of insertion and removal.

[0010] Optionally, the locking mechanism is an electro-mechanical linkage lock stop pin, which is driven by a micro motor to achieve automatic execution and release of the physical lock. This technical solution improves the reliability and automation of the locking mechanism.

[0011] Optionally, the mating connector is a floating adaptive high-power connector, wherein the female socket of the floating adaptive high-power connector is mounted on an elastic substrate to allow it to float within a preset range to absorb alignment errors. This technical solution further enhances the reliability of the electrical connection.

[0012] Optionally, the docking connector includes power contacts and data contacts; the pluggable smart battery module has an internal battery management system, which is used to report the power status data of the pluggable smart battery module to the smart docking base in real time through the data contacts. This technical solution provides a real-time data foundation for intelligent control.

[0013] Optionally, the pluggable smart battery module has an internal ID chip storing unique identification information; after the pluggable smart battery module is inserted, the smart docking base reads the unique identification information through the docking connector to authenticate the pluggable smart battery module.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] To address the technical problems of redundant energy waste and cumbersome battery maintenance in existing wind-solar integrated streetlights, this application provides an intelligent energy storage and rapid maintenance system for wind-solar integrated streetlights. In a specific implementation, this system adopts a highly integrated electromechanical docking architecture, integrating the energy interaction function and physical replacement operation of the energy storage battery into a single, atomic docking action. This enables automated collaborative transfer of redundant energy and tool-independent rapid replacement of battery modules. This method solves the technical problems of low energy utilization caused by isolated energy storage systems and low maintenance efficiency and high cost caused by fixed packaging design in existing technologies, achieving the beneficial effects of improving overall energy utilization efficiency and reducing the total life cycle maintenance cost.

[0023] Example 1 Reference Figure 1 and Figure 2 This embodiment provides an intelligent energy storage and rapid maintenance system for integrated wind and solar streetlights. In a specific application scenario, this system is deployed on urban roads, in industrial parks, or in remote areas to provide a stable, efficient, and easy-to-maintain energy storage solution for integrated wind and solar streetlights. The system includes an intelligent docking base 100 and a pluggable intelligent battery module 200.

[0024] The intelligent docking base 100 is designed as a standardized functional hub, securely fixed to the streetlight pole by bolts or clamps, typically at a height easily accessible to maintenance personnel. The intelligent docking base 100 includes a guide mechanism 110 for guiding the insertion of the pluggable intelligent battery module 200, a locking mechanism 120 for physically locking the pluggable intelligent battery module 200 after insertion, and a docking connector 130 for establishing an electrical connection with the pluggable intelligent battery module 200. These three core components work together to form the basis for the system's rapid and reliable docking.

[0025] The pluggable smart battery module 200, with its overall structure adapted to the internal space of the smart docking base 100, is designed as a standardized, independently replaceable energy storage unit. Guided by the guide mechanism 110, the pluggable smart battery module 200 smoothly inserts into the receiving compartment of the smart docking base 100, and is securely locked in place by the locking mechanism 120. This locking action simultaneously ensures precise engagement between the male connector on the pluggable smart battery module 200 and the docking connector 130 (female connector) within the smart docking base 100, thereby establishing a stable and reliable electrical connection. Through this design, the traditional battery replacement process, requiring multiple steps and tools, is completely simplified into a single tool-free "pull-in" operation.

[0026] In one specific embodiment, in order to ensure the accuracy of the docking process, the guide mechanism 110 is designed as a V-shaped self-aligning precision guide rail.

[0027] For example, the V-shaped self-aligning precision guide rail is precision machined from a single piece of 7075-T6 aerospace-grade aluminum alloy that has undergone hard anodizing treatment using a five-axis CNC machine tool, resulting in a high-hardness, wear-resistant oxide layer on its surface. The angle of the V-shaped groove of the guide rail is precisely set to 60.0 degrees, and the surface roughness is controlled to be below Ra 0.8 micrometers. This 60-degree V-angle design is the result of extensive simulation and experimental optimization. During the insertion of the pluggable smart battery module 200, when the module has an initial lateral alignment deviation of up to ±5.0 mm, a sufficiently large lateral correction force component orthogonal to it is generated along the V-shaped inclined surface by the component of the insertion force in the Z-axis direction. This correction force can effectively overcome friction and guide the pluggable smart battery module 200 to automatically converge towards the center reference line in the last 10.0 cm of insertion stroke, ultimately ensuring that the lateral and vertical position errors of the module when it reaches the locking position are strictly controlled within a tolerance zone of ±0.1 mm. This passive self-alignment mechanism greatly reduces the precision requirements for maintenance personnel. Even in poor lighting or limited space, it can ensure successful insertion on the first attempt, avoiding interface wear that may be caused by repeated alignment attempts.

[0028] Alternatively, the guide mechanism 110 may also be implemented in another high-precision manner, for example, by including at least a pair of parallel linear guides.

[0029] For example, the linear guide rails are made of high-carbon steel, and the surface of the rails is treated with high-frequency quenching and precision grinding, achieving a hardness of HRC60 or higher. Two parallel guide rails are fixedly installed on the inner wall of the intelligent docking base 100, while a matching slider is installed on the side wall of the pluggable intelligent battery module 200. The slider contains two rows of balls forming a circulating raceway, reducing the coefficient of friction between the slider and the guide rails to below 0.005. This design provides extremely high motion accuracy and rigidity, ensuring that the straightness deviation of the battery module's trajectory is less than 0.05 mm / m throughout the entire insertion and removal process, providing a solid foundation for the precise alignment of subsequent connectors and locking mechanisms.

[0030] To achieve automated and highly reliable locking, the locking mechanism 120 is preferably an electro-mechanical linkage locking pin.

[0031] For example, the core driving component of the electro-mechanical linkage lock pin is a high-torque miniature planetary gear reducer stepper motor, which provides precise angle control and an output torque of up to 2.0 Nm. The motor drives a cylindrical lock pin, made of 316L stainless steel with a diameter of 8.0 mm, to reciprocate linearly via a precision lead screw mechanism. The housing of the pluggable smart battery module 200 has a locking groove that precisely matches the lock pin. When the module is inserted into position and triggers the limit switch, the control unit inside the base drives the stepper motor to rotate a preset number of steps, causing the lock pin to extend precisely by 12.0 mm and fully engage in the groove. This locking method provides a tensile force of over 500 Newtons (equivalent to the weight of approximately 50 kg), sufficient to withstand vibrations and impacts from strong winds or vehicle collisions, ensuring the battery module does not accidentally detach. When replacement is needed, the control unit reverses the motor's direction, and the lock pin automatically and smoothly retracts, releasing the lock. The entire locking and unlocking process is controlled by electrical signals, with a response time of less than 1.0 second, requiring no manual intervention whatsoever.

[0032] Alternatively, the locking mechanism 120 may also be implemented in a way that has a faster response speed, such as an electromagnet attraction mechanism.

[0033] For example, the mechanism has a high-power, power-off retaining electromagnet installed on the inner rear wall of the intelligent docking base 100, with a rated holding force of up to 600 Newtons. A pure iron armature plate with excellent magnetic permeability is embedded and fixed on the corresponding end face of the pluggable intelligent battery module 200. When the battery module is pushed into place, the armature plate and the pole face of the electromagnet are tightly fitted. After confirming the positioning signal, the control unit applies a pulse current with a duration of 50 milliseconds to the electromagnet coil, which establishes a strong magnetic field to firmly attract the two. The characteristic of the power-off retaining electromagnet is that once attracted, even if the current is removed, its internal permanent magnet can maintain most of the attraction force, thus achieving zero power consumption in the locked state. When unlocking is required, the control unit applies a reverse pulse current to the coil, which cancels the permanent magnet magnetic field, achieving instantaneous release. This method has a locking and unlocking response time of less than 100 milliseconds and has no mechanical moving parts, resulting in higher reliability.

[0034] To address the challenges posed by repeated insertions and removals and minute alignment errors, the mating connector 130 is designed as a floating, adaptive high-power connector.

[0035] For example, the female connector of the floating adaptive high-power connector is not rigidly fixed to the housing of the smart docking base 100, but is mounted on an elastic substrate made of a highly elastic polymer (e.g., polyurethane elastomer). This substrate design allows the female connector to have a floating displacement space of 1.0 mm radius in the XY plane relative to the base housing. When the pluggable smart battery module 200 with a male connector is inserted, even after V-rail correction, there may still be a small (e.g., 0.1 mm) final alignment error. At the moment of contact between the male connector and the female connector, the female connector can adaptively fine-tune using its floating capability, thus achieving perfect alignment and avoiding pin bending or damage caused by rigid collisions. The power contacts of the connector adopt a multi-point contact crown spring structure, made of a highly conductive and highly elastic beryllium copper alloy, and are gold-plated to a thickness of 5.0 micrometers. This design ensures that the contact resistance at a single point remains below 0.5 milliohms throughout a mating life of more than 2,000 mating cycles, and can stably carry a continuous operating current of up to 50 amps, while the temperature rise is controlled within 15 degrees Celsius, providing a guarantee for efficient and safe power transmission.

[0036] Reference Figure 3 This illustrates the core workflow of the system in one embodiment. The working method of this system can be summarized into the following core steps: S100: Real-time system status monitoring This step is fundamental to the system's intelligent decision-making. In one embodiment, the pluggable smart battery module 200 integrates a high-precision Battery Management System (BMS). The docking connector 130 includes power contacts for high-current transmission as well as dedicated data contacts. The battery management system establishes a continuous communication link with the control unit within the smart docking base 100 through these data contacts.

[0037] S110: Battery Module Status Acquisition. The sampling circuit inside the battery management system continuously monitors the total voltage, charging and discharging current, and temperature of key cells of the battery pack at 10-millisecond intervals. Simultaneously, its internal microprocessor executes a coulomb calculation method based on ampere-hour integration combined with open-circuit voltage correction to calculate the remaining state of charge (SoC) of the battery in real time with high accuracy.

[0038] S120: Status Data Transmission. The battery management system collects and calculates real-time status data, including voltage values ​​(accurate to 0.01V), current values ​​(accurate to 0.1A), temperature values ​​(accurate to 0.5°C), and SoC values ​​(accurate to 0.1%), and packages them into a data frame. This data frame is broadcast once per second to the control unit within the smart docking base 100 and the street light's charging management module via an isolated CAN (Controller Area Network) bus protocol. This high-frequency data update ensures that the control unit can make decisions based on the latest and most accurate battery status.

[0039] S200: Intelligent Cooperative Transfer of Redundant Power This step aims to address the problem of wasted redundant energy after the battery is fully charged. The intelligent docking base 100 also includes a control unit 140 and an external energy storage interface 150. The core of the control unit 140 is an industrial-grade microcontroller (MCU), which is responsible for executing a preset, robust "state machine-based bidirectional energy storage coordination protocol," whose core state transition logic is as follows: Figure 3 As shown. This protocol defines a series of system operating states and state transition rules triggered by specific events or conditions, ensuring clear, reliable, and secure system decision-making. The states and their transition logic included in this protocol are as follows: After the system is powered on and initialized, it enters the STATE_CHARGING state by default. In this state, the control unit allows electrical energy from the charging management module to charge the battery module.

[0040] When the SoC value is detected to be greater than or equal to the full charge threshold (for example, 99.0%), the system state changes from STATECHARGING to STATEFORT_CHECK (float charge check state).

[0041] In STATEFORTCHECK state, the control unit starts an internal timer and continuously monitors the battery voltage and charging current. If, within a preset float charge confirmation time (exemplarily 300 seconds), the battery voltage remains stable at the float charge voltage plateau (exemplarily 28.8V ± 0.1V) and the charging current remains below the trickle charge threshold (exemplarily 0.5A), the battery is considered fully charged. At this time, the control unit attempts to establish a communication handshake with the external energy storage device via the external energy storage interface. If the handshake is successful, the state transitions to STATENERGYEXPORT (energy output state); if the handshake fails or the external device is not connected, the state transitions to STATEIDLEFULL (fully charged and idle state). If the voltage or current conditions are not met during the check, charging is considered incomplete, and the state reverts to STATE_CHARGING.

[0042] In the STATENERGY EXPORT state, the control unit closes the internal relay to begin transferring redundant power to the external energy storage device. During this process, if the System Capacity (SoC) is detected to drop to the transfer termination threshold (exemplarily 90.0%), the state transitions to STATEIDLEHIGH (high-power idle state), and the relay is disconnected. If communication with the external energy storage device is unexpectedly interrupted during this period, the state immediately transitions to STATEEXTERNALDISCONNECT (external disconnection fault state), and a safe power-off operation is performed.

[0043] At night or when there is insufficient light, the system will enter STATE_DISCHARGING (discharge state) to supply power to the lighting load.

[0044] Furthermore, the protocol defines multiple fault and anomaly handling states. For example, the STATEBATTERYFAULT state is entered when a critical fault code (such as over-temperature or over-voltage) is reported by the BMS; in this state, the system will disconnect all charging and discharging circuits and issue an alarm. The STATEHANDSHAKEFAILED state records failed communication attempts with external energy storage devices; the system will wait for a preset time in this state before retrying. This detailed state machine design ensures that the system can respond safely and appropriately under various expected and unexpected operating conditions.

[0045] S210: Full charge status determination. The control unit 140 continuously parses the data frames received from the battery management system. When it detects that the SoC data reaches or exceeds a preset full charge determination threshold for the first time, such as 99.0%, it does not take immediate action, but instead starts an internal timer to enter the float charge status confirmation stage.

[0046] S220: Float Charge Status Confirmation. To accurately determine whether the battery is truly fully charged and avoid misjudgments caused by instantaneous voltage fluctuations, the control unit 140 performs a dual-condition verification. It continuously monitors the battery's terminal voltage and charging current. If, after the timer accumulates to a preset float charge confirmation duration, such as 300 seconds (5 minutes), during this period, the battery voltage remains stable at a preset float charge voltage plateau, for example, 28.8V ± 0.1V for a 24V lithium iron phosphate battery system, and simultaneously the charging current remains consistently below a preset trickle charge threshold, such as 0.5A, then the system can determine with a very high degree of confidence that the battery has reached a true, fully charged state, i.e., entered the float charge stage.

[0047] S230: Energy Transfer Decision and Execution. Once the float charging state is confirmed, the control unit 140 sends an "energy output request" handshake signal to the connected external energy storage device (e.g., a mobile energy storage vehicle or a regional energy storage station) via the communication pin (e.g., RS485) of the external energy storage interface 150. After receiving a "ready" confirmation signal from the other party, the control unit 140 drives a high-power DC relay inside it to close. This relay securely connects the electrodes of the pluggable smart battery module 200 to the power bus of the external energy storage device through the docking connector 130 and the external energy storage interface 150. At this time, the redundant energy stored in the battery module begins to be transferred outward in a controlled manner.

[0048] S240: Power Transfer Termination. During the power transfer process, the control unit 140 continues to monitor the battery's System State (SoC) once per second. To reserve sufficient reserve power for the streetlights to cope with continuous rainy weather, not all power is transferred. When the SoC drops to a preset transfer termination threshold, such as 90.0%, the control unit 140 immediately disconnects the high-power DC relay, cutting off the power transmission path and stopping the energy transfer. Afterward, the system enters a "high-power standby" state, waiting for nightfall to power the lighting load.

[0049] S300: Zero-power rapid maintenance and replacement of battery modules This step is designed to make the battery replacement process extremely simple, safe, and efficient.

[0050] S310: Maintenance Request and Authorization. When the battery module needs to be replaced, maintenance personnel can send an encrypted and authenticated "replacement request" command to the smart docking base 100 of the target street light via a handheld dedicated maintenance terminal with wireless communication capabilities (such as Bluetooth or NFC). After verifying the legality of the command, the control unit 140 will initiate the preset maintenance replacement process. If the command verification fails, it will enter the STATEMAINTENANCEAUTH_FAILED (maintenance authorization failure state) and refuse to execute.

[0051] S320: Zero-Power Disconnect. Safety is paramount. Before performing any physical unlocking action, the control unit 140 first executes an electrical isolation procedure. It disconnects all internal relays connected to the power contacts of the mating connector 130, including those at the charging input and load output, ensuring that no voltage or current carries on the power contacts at the moment of insertion or removal. This step is crucial for achieving "zero-power hot-swapping," completely eliminating the possibility of electric arcs during live insertion or removal, which can severely damage connector contacts and even cause safety accidents.

[0052] S330: Unlocking the locking mechanism. After confirming that the electrical connection is completely disconnected, the control unit 140 drives the micro motor inside the electromechanical linkage lock pin 120 to rotate in the opposite direction, causing the lock pin to retract completely from the locking groove of the pluggable smart battery module 200, thus releasing the physical lock. At this time, the maintenance terminal will display the message "Unlock successful, can be removed".

[0053] S340: Physical Removal and Insertion. Maintenance personnel, without any tools, can smoothly remove the pluggable smart battery module 200 from the smart docking base 100 by holding the handle and following the direction of the V-shaped self-aligning precision guide rail 110. Subsequently, a fully charged new pluggable smart battery module 200 is aligned with the guide rail inlet and pushed forward. With the self-alignment of the V-shaped guide rail, the module slides into place easily and precisely.

[0054] S350: Automatic Locking and Power-On. When the new pluggable smart battery module 200 is fully pushed in, its end will contact a high-precision limit switch inside the smart docking base 100. Upon receiving the signal triggered by the limit switch, the control unit 140 immediately determines that the module is physically in place. At this time, it drives the locking pin 120 to extend, completing the physical locking of the new module. After locking, the control unit 140 will authenticate the new module by reading the unique identification information of the internal ID chip through data contacts and obtain its initial state. Only after all checks are passed will the control unit 140 sequentially close the relevant relays to power on the new battery and restore the system's normal charging or discharging operation. The entire replacement process, from receiving the command to resuming operation, takes no more than 3 minutes.

[0055] In summary, the intelligent energy storage and rapid maintenance system for integrated wind-solar streetlights provided in this application constructs a standardized, mechatronic docking platform by combining an intelligent docking base with pluggable intelligent battery modules.
