[0045] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0046] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0047] Figure 1 This is a schematic diagram of the structure of a battery leakage monitoring device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the energy storage battery leakage monitoring device is used for monitoring leakage of battery modules inside the energy storage container, and includes: a main control module 101, a data acquisition module 102, a data processing and analysis module 103, a storage module 104, and a container control module 105.

[0048] The output of the data acquisition module 102 is connected to the main control module 101. The data acquisition module 102 is used to acquire real-time status data of the battery modules inside the energy storage container. The storage module 104 is connected to the main control module 101. The storage module 104 is used to store historical status data of the battery modules inside the energy storage container. The data processing and analysis module 103 is connected to the main control module 101. The data processing and analysis module 103 is used to receive and compare historical status data and real-time status data sent by the main control module 101. The container control module 105 is connected to the main control module 101. The container control module 105 is used to control the opening or closing of the energy storage container door and the opening or closing of the main control power supply of the battery modules.

[0049] Specifically, the data acquisition module 102 is used to collect real-time status data of the battery modules inside the energy storage container. For example, when detecting leakage in the battery modules inside the energy storage container, leakage is detected from multiple dimensions, including humidity detection, gas detection, and electrical detection. Optionally, the data acquisition module 102 includes humidity sensors, gas sensors, voltage sensors, and current sensors. These sensors are connected to the battery modules to collect real-time status data such as humidity, gas, and electrical data; or they can be placed around the battery modules to collect environmental data about the surrounding environment to detect leakage.

[0050] Storage module 104 is used to store historical status data of the battery modules inside the energy storage container. For example, storage module 104 uses a Flash memory chip and is connected to the main control module 101 via an SPI bus to store historical operating data of the battery modules. After the data acquisition module 102 of the battery leakage detection device acquires real-time status data of the battery modules, it stores this real-time status data in storage module 104 as historical status data. This historical status data can also serve as one of the criteria for determining whether the battery modules are leaking.

[0051] The data processing and analysis module 103 is used to compare real-time data with historical data to identify abnormal fluctuations. For example, the data processing and analysis module 103 incorporates a high-speed comparator array and an FPGA chip, enabling it to compare real-time data with historical data to determine if the battery module is leaking. Optionally, the data processing and analysis module 103 acts as a comparator circuit, directly comparing the real-time acquired voltage, current, and temperature signals with historical data stored in the module in parallel, and determining whether the battery module is leaking based on the output of the comparator circuit.

[0052] The container control module 105 is used to control the opening of the energy storage container door and the shut-off of the main power supply for the battery modules. In an energy storage container, there are multiple battery modules inside. Upon detecting leakage, the main power supply to the battery modules in the energy storage container is shut off. For example, the container control module 105 includes a relay switch and a motor drive circuit, connected to the main control module via an output port to execute power-off or door-opening commands. In this embodiment of the invention, the energy storage battery leakage monitoring device, after determining that a battery module is leaking, executes power-off or door-opening commands through the container control module 105 to achieve automated processing. Personnel do not need to enter the site; the energy storage battery leakage monitoring device automatically operates to cut off power and open the door after a leak occurs, providing a rapid response and safe handling method.

[0053] The main control module 101 is responsible for coordinating the data interaction between the modules. Optionally, the main control module 101 may include a microcontroller or an embedded processor, which is not limited here.

[0054] For example, the data acquisition module 102, acting as a sensor circuit, acquires signals such as voltage, current, temperature, gas, and humidity information of the battery module in real time and transmits them to the main control module 101. The main control module 101 retrieves historical data from the storage module 104 and sends it along with the real-time data to the data processing and analysis module 103. The data processing and analysis module 103 determines whether leakage has occurred through threshold comparison or trend comparison. If an anomaly is detected, the main control module 101 cuts off the main power supply to the battery module through the container control module 105, and simultaneously drives the motor to unlock the container door, achieving rapid ventilation and electrical isolation.

[0055] In the energy storage battery leakage monitoring device of this embodiment, the data acquisition module acquires real-time status data of the battery module and transmits it to the main control module. The main control module retrieves historical status data from the storage module and sends it along with the real-time status data to the data processing and analysis module. The data processing and analysis module determines whether leakage has occurred based on the real-time and historical status data. If an anomaly is detected, the main control module cuts off the main power supply to the battery module through the container control module and simultaneously opens the container door to achieve rapid ventilation and electrical isolation. The energy storage battery leakage monitoring device of this embodiment achieves fully automated leakage emergency handling, reduces manual intervention in leakage handling, and improves safety.

[0056] Based on the above embodiments, Figure 2 This is a schematic diagram of another energy storage battery leakage monitoring device provided in this embodiment of the present invention, as shown below. Figure 2 As shown, the storage module 104 includes: a data storage unit 1041, a data update unit 1043, and a data retrieval unit 1042; the input terminal of the data storage unit 1041 is connected to the main control module 101, and the data storage unit 1041 is used to receive and store real-time status data sent by the main control module 101; the first control terminal of the data storage unit 1041 is connected to the output terminal of the data retrieval unit 1042, the control terminal of the data retrieval unit 1042 is connected to the main control module 101, and the input terminal of the data retrieval unit 1042 is connected to the output terminal of the data storage unit 1041; the output terminal of the data retrieval unit 1042 is connected to the main control module 101; the data retrieval unit 1042 is used to retrieve data within a first preset time period of the data storage unit 1041; the second control terminal of the data storage unit 1041 is connected to the output terminal of the data update unit 1043, and the data update unit 1043 is used to delete data outside the second preset time period of the data storage unit 1041, the second preset time period being greater than or equal to the first preset time period.

[0057] Specifically, the data storage unit 1041 is connected to the main control module 101 via the SPI bus, and receives and stores the status data of the battery module in real time. For example, the data storage unit 1041 is a flash memory, and it stores status data from the current period to a previous period.

[0058] The data retrieval unit 1042 is connected to the data storage unit 1041. The control terminal receives the retrieval command from the main control module 101, retrieves data within a first preset duration from the data storage unit 1041 according to the timestamp index, and transmits it to the main control module via the bus. Optionally, the first preset duration is 30 minutes.

[0059] The data update unit 1043 is used to update the data stored in the data storage unit 1041. For example, the data update unit 1043 integrates an erase controller and a timer circuit. The timer generates an erase pulse according to a second preset duration, triggering the erase controller to perform block erasure of old data in the data storage unit 1041 that exceeds the preset duration, thereby releasing storage space. Optionally, when the first preset duration is 30 minutes, the second preset duration is greater than 30 minutes.

[0060] For example, the main control module 101 writes real-time status data of the battery modules inside the energy storage container to the data storage unit 1041 via the SPI bus, and sends a retrieval command to the data retrieval unit 1042; optionally, the retrieval command includes a time range parameter. The data retrieval unit 1042 selects the corresponding data to be retrieved according to the retrieval command, and transmits the data back to the main control module 101 via the SPI bus. The data update unit 1043 periodically triggers the erasure of the corresponding historical status data.

[0061] The energy storage battery leakage monitoring device of this utility model realizes automated and efficient management of battery module data through storage, retrieval and update units, improving storage utilization and system response speed; at the same time, this utility model embodiment does not require the main control module to store data, reducing the resource occupation of the main control module and enhancing the reliability of the energy storage monitoring device.

[0062] Based on the above embodiments, Figure 3 This is a schematic diagram of another energy storage battery leakage monitoring device provided in this embodiment of the present invention, as shown below. Figure 3As shown, the data processing and analysis module 103 includes a comparison unit 1041 and a control signal generation unit 1032. The input terminal of the comparison unit 1041 is connected to the main control module 101, the output terminal of the comparison unit 1041 is connected to the input terminal of the control signal generation unit 1032, and the output terminal of the control signal generation unit 1032 is connected to the main control module 101. The comparison unit 1041 receives historical state data and real-time state data for comparison, and the control signal generation unit 1032 generates a battery module state signal based on the comparison result. The battery module state signal includes a first electrical signal and a second electrical signal. The first electrical signal indicates that the battery module is leaking electrolyte, and the second electrical signal indicates that the battery module is not leaking electrolyte.

[0063] Specifically, the comparison unit 1041 in the data processing and analysis module 103 is connected to the main control module 101, receives real-time status data and historical status data retrieved by the storage module, and determines the data differences. For example, the data processing and analysis module 103 can be a comparator circuit, which determines the differences between historical and real-time status data through threshold comparison or trend analysis.

[0064] The control signal generation unit 1032 receives the output signal from the comparison unit 1041 at its input terminal and generates two electrical signals based on the comparison result. The first electrical signal is a leakage indication signal, optionally a high-level pulse signal, which triggers the main control module 101 to initiate emergency control. The second electrical signal is a normal state signal, a continuous low-level signal, maintaining routine system monitoring. For example, the control signal generation unit 1032 is a logic gate circuit.

[0065] For example, the main control module 101 synchronously transmits the real-time status data collected in real time and the historical status data retrieved by the storage module to the comparison unit 1041. The comparison unit 1041 compares the real-time status data with the historical status data through hardware circuitry. If battery module leakage is detected, a high-level signal is output to the control signal generation unit 1032. The control signal generation unit 1032 generates a first electrical signal based on the high-level input, triggering the main control module 101 to immediately cut off the power and open the container door; if there is no abnormality, a second electrical signal is output, and the system maintains the monitoring state. The comparison unit 1041 compares the real-time data with the historical data through hardware circuitry, performing different types of comparisons based on the different battery module status data collected in the energy storage container; this is not limited here.

[0066] Based on the above embodiments, the output terminal of the container control module 105 is connected to the container control system, and the input terminal of the container control module 105 is connected to the main control module 101. The container control module 105 is used to control the opening of the energy storage container door and the shut-off of the main control power of the battery module according to the first electrical signal.

[0067] Specifically, the container control module 105 is used to control the opening of the energy storage container door and the shut-off of the main power supply of the battery module according to the first electrical signal. For example, the container control system includes a relay switch unit connected in series in the main power line of the battery module. Its input terminal is connected to the container control module 105 to receive the first electrical signal and trigger the contacts to open, thus cutting off the power. The container control system also includes a door drive unit, which is a DC geared motor. The door drive unit is connected to the container control module 105 and drives the gear set to rotate after receiving the first electrical signal from the container control module 105, thereby automatically opening the door.

[0068] The energy storage battery leakage monitoring device of this utility model controls the container control system through the container control module to open the energy storage container door and shut down the main control power of the battery module. This enables rapid power cut-off and automatic door opening in the event of leakage, ensuring the real-time and reliable safety response, reducing the risk of manual intervention, and improving the overall safety of the energy storage system.

[0069] Based on the above embodiments, Figure 4 This is a schematic diagram of another energy storage battery leakage monitoring device provided in this embodiment of the present invention, as shown below. Figure 4 As shown, the energy storage battery leakage monitoring device includes: a battery management module 106 and a backup battery; the battery management module 106 is connected to the main control module 101, and the battery management module 106 is used to control the backup battery to supply power to the energy storage battery leakage monitoring device according to the first electrical signal.

[0070] Specifically, the energy storage battery leakage monitoring device is equipped with a battery management module 106 and a backup battery to form a redundant power supply system. The battery management module 106 is connected to the main control module 101, receives a first electrical signal, and its output is connected to both the main power line and the backup battery to achieve power supply switching. The backup battery is connected to the battery management module 106 and is normally charged by the main power supply; when the main power supply is interrupted, it switches to power supply from the backup battery. Optionally, the battery management module 106 consists of a power switching circuit and a voltage monitoring chip. The voltage monitoring chip receives the first electrical signal, and the power switching circuit switches the power supply to the backup battery; the backup battery is a rechargeable lithium-ion battery pack.

[0071] The energy storage battery leakage monitoring device provided in this embodiment of the utility model, through a hardware-based battery management module and backup battery design, seamlessly switches to backup power after the main power is cut off due to leakage, ensuring continuous operation of the monitoring device, avoiding interruption of critical functions, and improving the reliability and safety of the system in emergency situations.

The gas acquisition module 1021 is used to collect real-time air data of the energy storage container.

Optionally, the gas acquisition module 1021 is a metal-oxide-semiconductor sensor. The humidity acquisition module 1022 has sensor probes positioned around the battery module in the energy storage container, communicating with the main control module via a serial bus to monitor changes in humidity around the battery module.

[0076] Based on the above embodiments, Figure 6 This is a schematic diagram of another energy storage battery leakage monitoring device provided in this embodiment of the present invention, as shown below. Figure 6As shown, the energy storage battery leakage monitoring device includes: an alarm module 107 and a communication module 108. The alarm module 107 is connected to the main control module 101 and is used to issue an alarm based on the data comparison results of the data processing and analysis module 103. The communication module 108 is connected to the main control module 101 and is used to send the alarm operation of the alarm module 107 and / or the data comparison results of the data processing and analysis module 103 to an external host computer through a communication transmitter.

[0077] Specifically, the alarm module 107 is used to trigger an alarm. When a leak is detected, the alarm module 107 immediately activates the audible and visual alarm device and sends the alarm information to the host computer via the communication module 108, facilitating timely handling by management personnel. The data transmission between the communication module 108 and the host computer ensures that alarm information and monitoring data can be quickly and reliably delivered to management personnel.

[0078] Based on the above embodiments, Figure 7 This is a schematic diagram of another energy storage battery leakage monitoring device provided in this embodiment of the present invention, as shown below. Figure 7 As shown, the energy storage battery leakage monitoring device includes: a main control module 101, a data acquisition module 102 including a gas acquisition module 1021, a humidity acquisition module 1022, a current acquisition module 1023, a voltage acquisition module 102, and a temperature sensor acquisition module 1025; a data processing and analysis module 103 including a comparison unit 1031 and a control signal generation unit 1032; a storage module 104 including a data storage unit 1041, a data retrieval unit 1042, and a data update unit 1043; a container control module 105; and an alarm module 107 for audible and visual alarms.

[0079] The energy storage battery leakage monitoring device collects environmental and electrical status parameters of the battery module in real time. Combined with historical data comparison and analysis, it automatically cuts off the power supply, opens the container door and triggers an alarm when leakage occurs. At the same time, the backup battery management module 106 ensures the continuity of power supply, realizing fully automated safety monitoring and emergency response of the energy storage container.
