Description

Technical Field

[0001] This invention relates to the field of battery swapping cabinet technology, and in particular to a battery swapping cabinet with a detection device. Background Technology

[0002] Driven by the "dual carbon" goals and the rapid development of the on-demand delivery industry, electric bicycle battery swapping stations, as a key infrastructure of urban green transportation systems, are ushering in significant development opportunities. This model provides standardized, safe, and compliant batteries (such as lithium iron phosphate batteries) for centralized charging and management, replacing inferior batteries used by users or illegally modified (such as batteries assembled from recycled cells or illegally expanded batteries), effectively alleviating the "range anxiety" of users (especially on-demand delivery riders). At the same time, this centralized management significantly reduces the risk of fire caused by unauthorized wiring, illegal indoor charging, the circulation of inferior batteries, and illegal battery modifications.

[0003] Existing battery swapping cabinets typically consist of multiple swapping compartments equipped with modules such as chargers, smoke sensors, and fire extinguishing devices. The controller is responsible for opening and closing the compartment doors, controlling indicator light status, and managing charging, and interacts with a cloud platform via a communication module. However, current technologies mostly rely on passive, reactive protection methods such as smoke sensors triggering fire extinguishing devices, and generally lack real-time proactive detection of battery electrical performance and overall safety status. This makes it impossible to implement protection before potential hazards occur and hinders the implementation of safer and smarter charging control strategies.

[0004] Therefore, how to provide a battery swapping cabinet with a detection device to improve the active safety protection capability and intelligent management level of the battery swapping cabinet has become an urgent technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a battery swapping cabinet with a detection device, thereby improving the active safety protection capability and intelligent management level of the battery swapping cabinet.

[0006] This invention is implemented as follows: a battery swapping cabinet with a detection device, comprising:

[0007] A battery swapping cabinet controller;

[0008] Several battery swapping compartments are connected to the battery swapping cabinet controller and are equipped with at least one charger, at least one smoke sensor, at least one aerosol fire extinguisher, at least one compartment door lock, and at least one status indicator light.

[0009] A platform interface communication module is connected to the battery swapping cabinet controller;

[0010] Several battery safety detection devices are connected to the battery swapping cabinet controller and the charger;

[0011] The battery safety detection device includes:

[0012] A detection controller;

[0013] A voltmeter for detecting battery voltage, with its control terminal connected to the detection controller;

[0014] An ammeter for detecting the charging and discharging current of a battery, with its control terminal connected to the detection controller and its detection terminal connected to the charger;

[0015] A battery charging circuit switch for switching the battery charging circuit on and off, with the control terminal connected to the detection controller and the charger;

[0016] A battery communication circuit switch for switching the battery communication circuit on and off, with its control terminal connected to the detection controller and to the charging communication line of the battery swapping cabinet controller;

[0017] An AC internal resistance detection module for detecting the AC internal resistance of a battery, with its control terminal connected to the detection controller;

[0018] A sub-communication module is connected to the detection controller.

[0019] Furthermore, the sub-communication module is also connected to the platform interface communication module.

[0020] Furthermore, the battery charging circuit switch is in the off state by default.

[0021] Furthermore, the battery communication circuit switch is in the off state by default.

[0022] Furthermore, the door lock is an electronic lock.

[0023] Furthermore, the status indicator light is a three-color indicator light.

[0024] Furthermore, the communication module that the platform interfaces with is at least one of a 4G LTE module, a 5G module, an Ethernet module, a Wi-Fi module, or an NB-IoT module.

[0025] Furthermore, the sub-communication module is at least one of a 4G LTE module, a 5G module, an Ethernet module, a Wi-Fi module, or an NB-IoT module.

[0026] The advantages of this invention are:

[0027] 1. By integrating a battery safety detection device into the battery swapping cabinet, real-time active monitoring of battery voltage, current, and internal resistance is achieved. Combined with the physical isolation of the charging circuit and communication circuit switches that are disconnected by default, this breaks through the traditional passive protection mode that relies on smoke sensors. The detection controller dynamically predicts battery risks based on multi-dimensional data and links the battery swapping cabinet controller to execute intelligent charging strategies (such as current limiting or terminating charging). At the same time, the data is synchronized to the cloud platform through the platform's communication module or sub-communication module. Combined with electronic locks and three-color indicator lights, the faulty batteries are automatically locked and their status is visualized, thereby proactively intervening before potential hazards occur. Furthermore, relying on cloud platform data analysis, battery scheduling and maintenance strategies are optimized, ultimately greatly improving the active safety protection capabilities and intelligent management level of the battery swapping cabinet.

[0028] 2. The battery safety testing device integrates a voltmeter, ammeter, AC internal resistance detection module, etc., which can measure battery parameters (voltage, current, internal resistance) in multiple dimensions. For example, AC internal resistance detection can accurately assess changes in battery internal resistance, predict aging or faults, and automatically shut off the charging circuit in conjunction with the detection controller to prevent overcharging or damage to the battery, effectively improving battery life and availability, and reducing replacement costs.

[0029] 3. Both the battery charging circuit switch and the battery communication circuit switch are open by default and will only close after the detection is passed. This effectively isolates the power supply and communication risks of abnormal batteries, avoids potential short circuits due to human error or automatic processes, and ensures that only healthy batteries can be charged and discharged.

[0030] 4. By adopting three-color status indicator lights and electronic compartment door locks, the status inside the compartment can be displayed intuitively (such as green light indicating idle, yellow light indicating charging, and red light indicating fault), making it convenient for users to quickly identify available compartments; the electronic locks are managed uniformly through the battery swapping cabinet controller, enhancing the convenience of operation and theft prevention.

[0031] 5. The platform's communication module and sub-communication modules support multiple technologies (such as 4G, 5G, Wi-Fi, NB-IoT) to ensure stable data upload to the cloud platform. The sub-communication modules connect with the platform's communication module to enable battery-level data monitoring (such as current and voltage) and remote control. For example, the charging and discharging strategies can be adjusted in real time through the cloud platform, effectively improving the system's scalability and environmental adaptability (covering urban or remote areas), supporting big data analysis and predictive maintenance, and promoting smart grid or IoT applications.

[0032] 6. The overall architecture is centered on the battery swapping cabinet controller, which coordinates multiple battery swapping compartments and safety detection devices (each compartment has independent components) to form a modular unit, which facilitates the replacement or upgrading of components (such as the failure of a single compartment sensor does not affect the whole). Combined with communication flexibility, it supports large-scale deployment, effectively reduces life cycle costs, and adapts to high-throughput scenarios.

[0033] 7. The battery safety detection device automatically controls the charging and discharging circuit to avoid wasting energy on faulty batteries. Combined with status indicator lights, it achieves precise management. The default disconnect switch design also reduces standby power consumption, thus effectively improving energy utilization and environmental benefits.

[0034] 8. By integrating smoke sensors, aerosol fire extinguishers, and multi-parameter battery safety detection devices (including voltage, current, AC internal resistance monitoring, and dual-circuit switch isolation), a dual safety barrier of active fire protection and battery health diagnosis is constructed. Combined with the default disconnected charging / communication circuit switch design, abnormal batteries can be accurately isolated to avoid overcharging or short circuit risks, significantly improving equipment reliability. At the same time, its modular communication architecture (supporting multiple protocols such as 4G / 5G / Wi-Fi) and the linkage of three-color status indicator lights and electronic locks enable remote platform-based monitoring, user operation visualization management, and efficient operation and maintenance. Overall, it represents a breakthrough optimization in safety, intelligence, and user experience, and can be widely used in shared battery swapping scenarios to achieve efficient and safe battery lifecycle management.

[0035] 9. Active Protection: Real-time monitoring of battery electrical performance, such as voltage, current, and internal resistance, via a battery safety detection device, combined with safe charging logic, enables proactive protection of the battery, overcoming the shortcomings of existing battery swapping cabinets' post-event protection. Strong Compatibility: Two integration forms (highly integrated and extended) adapt to different scenarios. The highly integrated form is suitable for new battery swapping cabinet production, while the extended form allows for the modification of existing battery swapping cabinets without significant adjustments to the original control logic. Flexible Function Expansion: In the highly integrated form, the battery swapping cabinet controller can utilize detection data to achieve complex charging strategy optimization and battery health assessment functions. Enhanced Safety: Through secondary protection functions (such as disconnecting the charging circuit upon detecting an anomaly), combined with smoke sensors and aerosol fire extinguishers, multi-layered safety protection is formed, reducing fire risk. Efficient Data Management: The highly integrated form centrally manages detection data through the battery swapping cabinet controller, while the extended form directly uploads data to the cloud platform through an independent sub-communication module, both achieving effective utilization and monitoring of detection data.

[0037] Figure 1 This is a circuit diagram of a battery swapping cabinet with a detection device according to the present invention. Detailed Implementation

[0038] The overall concept of the technical solution in this application embodiment is as follows: By integrating a battery safety detection device into the battery swapping cabinet, real-time active monitoring of battery voltage, current, and internal resistance is achieved. Physical isolation is achieved by combining the default disconnected charging circuit and communication circuit switch, breaking through the traditional passive protection mode that relies on smoke sensors. The detection controller dynamically predicts battery risks based on multi-dimensional data, and links the battery swapping cabinet controller to execute intelligent charging strategies. At the same time, the data is synchronized to the cloud platform through the platform interface communication module or sub-communication module. Combined with electronic locks and three-color indicator lights, the faulty battery is automatically locked and its status is visualized, thereby proactively intervening before potential hazards occur. The battery scheduling and maintenance strategies are optimized based on cloud platform data analysis to improve the active safety protection capability and intelligent management level of the battery swapping cabinet.

[0039] Please refer to Figure 1 As shown, a preferred embodiment of the battery swapping cabinet with a detection device according to the present invention includes:

[0040] A battery swapping cabinet controller is used to control the operation of the battery swapping cabinet;

[0041] Several battery swapping compartments are connected to the battery swapping cabinet controller and are equipped with at least one charger, at least one smoke sensor, at least one aerosol fire extinguisher, at least one compartment door lock, and at least one status indicator light. The charger of each battery swapping compartment is connected to the battery through a battery safety detection device. Specifically, the P+_IN of the battery safety detection device is connected to the charger's P+ output, and the P+_OUT is connected to the battery's P+; the P-_IN is connected to the charger's P- output, and the P-_OUT is connected to the battery's P-; the communication IN is connected to the charging communication line, and the communication OUT is connected to the battery's battery communication line (RS485 / CAN).

[0043] Several battery safety detection devices are connected to the battery swapping cabinet controller and the charger;

[0044] The battery safety detection device includes:

[0045] A detection controller is responsible for collecting relevant data, controlling relevant switches, performing relevant charging protection, and implementing electrical performance testing and safety testing. In specific implementation, when performing the testing function, either the battery swapping cabinet controller or the detection controller can be used as the main controller to lead the testing. When the battery swapping cabinet controller is used as the main controller, the detection controller is only used for data acquisition and transmission.

[0046] A voltmeter for detecting battery voltage, with its control terminal connected to the detection controller;

[0047] An ammeter for detecting the charging and discharging current of a battery, with its control terminal connected to the detection controller and its detection terminal connected to the charger;

[0048] A battery charging circuit switch for switching the battery charging circuit on and off, with the control terminal connected to the detection controller and the charger; the battery charging circuit switch is connected in series in the charging circuit of the battery swapping cabinet and the battery to realize charging protection. The left IN is connected to the charging power line (charger) of the battery swapping cabinet, and the right OUT is connected to the battery power line of the battery. It is in the off state by default, is energized during operation, and is disconnected during protection.

[0049] A battery communication circuit switch for switching the battery communication circuit on and off is connected to the detection controller and the charging communication line of the battery swapping cabinet controller. The battery communication circuit switch is connected in series in the communication circuit between the battery swapping cabinet and the battery for switching between communication data hijacking and non-hijacking. The left IN is connected to the charging communication line of the battery swapping cabinet controller, and the right OUT is connected to the battery communication line of the battery. When the switch is engaged, the detection controller does not participate in the communication between the battery swapping cabinet and the battery and is in the off state by default.

[0050] An AC internal resistance detection module for detecting the AC internal resistance of a battery, with its control terminal connected to the detection controller;

[0051] A sub-communication module, connected to the detection controller, is used for external communication to report data or receive control commands.

[0052] The sub-communication module is also connected to the platform interface communication module.

[0053] When the sub-communication module connects to the platform's communication module, it is highly integrated. The battery safety detection device is a component of the battery swapping cabinet controller, which includes detection function-related logic. The detection business logic includes:

[0054] a. The detection business logic is executed in the detection controller. The detection controller autonomously completes data acquisition, analysis, and protection control (such as disconnecting the power circuit), and reports the results to the battery swapping cabinet controller.

[0055] b. All detection business logic is implemented in the battery swapping cabinet controller. The battery safety detection device only serves as a data acquisition (voltage, current, internal resistance, etc.) and execution component (such as switch control), receiving instructions from the battery swapping cabinet controller and feeding back data.

[0056] The battery swapping cabinet controller can combine battery safety detection devices with the charging compartment to achieve complex functions (such as dynamically adjusting the charging strategy based on the battery status).

[0057] When the sub-communication module is not connected to the platform communication module, it is an extended type. The battery safety detection device is connected in series with the power circuit and communication circuit of the battery swapping cabinet and the battery, but it is not coupled with the battery swapping cabinet controller for communication control. The battery safety detection device interacts directly with the cloud platform through the sub-communication module to upload detection data or receive control commands.

[0058] The battery charging circuit switch is in the off state by default.

[0059] The battery communication circuit switch is in the off state by default.

[0060] The door lock is an electronic lock.

[0061] The status indicator light is a three-color indicator light.

[0062] The platform's communication module is at least one of a 4G LTE module, a 5G module, an Ethernet module, a Wi-Fi module, or an NB-IoT module.

[0063] The sub-communication module is at least one of a 4G LTE module, a 5G module, an Ethernet module, a Wi-Fi module, or an NB-IoT module.

[0064] This invention integrates multiple protection functions, enabling not only post-incident protection but also proactive protection through pre-incident electrical performance and safety testing. This reduces the risk of battery thermal runaway from the source, significantly improving the safety of the battery swapping cabinet. It also enables safe charging by monitoring and protecting the charging process in real time, preventing safety accidents caused by charging anomalies.

[0065] Working principle of this invention:

[0066] Step S1: When swapping batteries, take out a fully charged battery from the battery swapping compartment of the battery swapping cabinet, put the depleted battery into the battery swapping compartment, and connect it to the battery safety detection module.

[0067] Step S2: The detection controller operates in communication data hijacking mode. The detection controller obtains the data read command sent by the battery swapping cabinet controller through the charging communication line, and forwards the data read command to the battery through the battery communication line; the detection controller obtains the battery charging data through the battery communication line, and forwards the charging data to the battery swapping cabinet controller through the charging communication line; before forwarding the data read command or running data, the data read command or running data is parsed and modified based on a preset communication protocol;

[0068] Step S3: The detection controller obtains the data monitoring command sent by the battery swapping cabinet controller through the charging communication line, closes the battery communication circuit switch based on the data monitoring command, and switches to the communication data monitoring mode (without the function of sending commands) to monitor the communication bus composed of the charging communication line and the battery communication line (monitoring can be performed from one side only).

[0069] Step S4: The controller detects the voltage accuracy using a voltmeter;

[0070] Step S5: The detection controller closes the battery charging circuit switch, the current accuracy is detected by the ammeter, the AC internal resistance is detected by the AC internal resistance detection module, and the DC internal resistance is detected by the voltmeter and ammeter.

[0071] Step S6: The detection controller performs safety monitoring on the battery charging data and the monitored BMS data through a preset monitoring threshold. When a safety event is detected, the battery charging circuit switch is disconnected to perform local safety protection operations.

[0072] Step S7: The battery swapping cabinet controller uploads electrical performance data, status data, charging data, and identity information to the cloud platform via the platform connection communication module. The electrical performance data includes voltage accuracy, current accuracy, AC internal resistance, and DC internal resistance. The status data includes battery charging status and battery safety detection module operating status. The identity information is the battery's unique identifier. In specific implementations, electrical performance data, status data, charging data, and identity information can also be uploaded to the cloud platform via a sub-communication module, supporting real-time upload (critical data), timed upload (trend analysis data), and event-triggered upload (abnormal status).

[0073] Step S8: The cloud platform creates a full life cycle information database for the battery based on the received electrical performance data, status data, charging data, and identity information. It then performs intelligent analysis on the data stored in the full life cycle information database and conducts safety management and control of the battery swapping cabinet based on the analysis results.
