[0048] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0050] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0052] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, the user should consider such a combination of technical solutions to be non-existent and not within the scope of protection claimed by this utility model.

[0053] It should be noted that, due to the rapid development of new energy sources, battery modules are now used more widely. The value of battery modules themselves and the scenarios in which they are used create a risk of them being stolen.

[0054] Battery modules are often deployed in remote areas, such as base stations in mountainous regions. Due to this location, users cannot monitor the equipment in real-time, significantly increasing the loss rate. Current anti-theft methods include adding electronic locks and latches to the battery module installation cabinet and affixing warning labels. However, even with these measures, battery modules are easily lost when unattended. Furthermore, users are not promptly notified of the theft, severely impacting the normal operation of the base station. The inability to recover stolen lithium battery modules results in financial losses for customers. Therefore, locating lost lithium battery modules is a pressing technical problem that needs to be solved.

[0055] To address the aforementioned technical problems, this embodiment provides a positioning circuit for a battery module. This embodiment includes a positioning circuit within the battery module, with a first positioning module housed inside the battery module and connected to a communication module. The first positioning module determines the current position of the battery module when it detects that the current angle signal of the battery module is greater than a preset angle signal, generates a corresponding position signal, and transmits the position signal to the communication module. Upon receiving the position signal, the communication module outputs the position signal to the user terminal. Compared to existing methods, this invention enables real-time positioning of the battery module through the first positioning module and transmits the position signal to the user terminal, thereby facilitating the tracking of lost battery modules.

[0056] For ease of understanding, the following is combined with Figures 1 to 7 The positioning circuit of the battery module provided in this embodiment of the present invention will be described in detail.

[0057] Reference Figure 1 This is a schematic diagram of the first embodiment of the positioning circuit proposed in this utility model.

[0058] like Figure 1 As shown, in this embodiment, the positioning circuit of the battery module may include: a first positioning module 1 and a communication module 2; the first positioning module 1 is disposed inside the battery module and is connected to the communication module 2;

[0059] It should be noted that the aforementioned battery module can be a lithium battery module used in remote base stations, or other battery modules that can power base stations. The aforementioned first positioning module 1 can be a module with positioning functionality, such as a Bluetooth first positioning module, a GPS first positioning module, or a BeiDou first positioning module. The aforementioned communication module 2 can be a module with communication capabilities with a terminal or user terminal, such as a 4G communication module, a 5G communication module, or a cellular communication module.

[0060] In order to transmit location signals to the user terminal, such as Figure 1 In this embodiment, the first positioning module 1 is used to determine the current position of the battery module, generate a corresponding position signal, and transmit the position signal to the communication module 2 when the current angle signal of the battery module is detected to be greater than the preset angle signal.

[0061] The communication module 2 is used to output the location signal to the user terminal when it receives the location signal.

[0062] It is understandable that the aforementioned current angle signal can be an electrical signal representing the tilt angle of the aforementioned battery module.

[0063] It should be noted that the preset angle signal can be 15 degrees or 20 degrees, and the specific angle signal can be set according to the actual situation. This embodiment does not impose any restrictions on this. The position signal can be an electrical signal indicating the position of the battery module in space.

[0064] It should also be noted that the aforementioned user terminal can be a device with remote signal receiving capabilities, such as a mobile phone, computer, or tablet.

[0065] In practice, when a thief steals the battery module from the base station, the battery module's angle relative to the horizontal changes continuously as it moves. Therefore, when the first positioning module 1 detects that the current angle signal of the battery module is greater than the preset angle signal, it determines that the battery module has been stolen, determines the current position of the battery module, generates a corresponding position signal, and then transmits the position signal to the communication module 2. When the communication module 2 receives the position signal, it immediately transmits the position signal to the user terminal, that is, informing the staff that the battery module has been stolen and needs to be tracked.

[0066] Furthermore, in order to output the position signal to the aforementioned communication module 2, continue as follows: Figure 1 In this embodiment, the first positioning module 1 includes the positioning unit 11 and the connection unit 12.

[0067] The aforementioned connection unit 12 is connected to the aforementioned communication module 2 and the aforementioned positioning unit 11, respectively;

[0068] It should be noted that the aforementioned positioning unit 11 can be a unit with positioning function, such as GPS, BeiDou, Wi-Fi, or cellular network. The aforementioned connection unit 12 can be a unit that outputs a position signal for the battery module.

[0069] The positioning unit 11 is used to determine the current position of the battery module, generate a corresponding position signal, and transmit the position signal to the connection unit 12 when the current angle signal of the battery module is detected to be greater than the preset angle signal.

[0070] The aforementioned connection unit 12 is used to transmit the aforementioned position signal to the aforementioned communication module 2.

[0071] In a specific implementation, when the positioning unit 11 detects that the current angle signal of the battery module is greater than the preset angle signal, it determines that the battery module has been stolen by a thief. Therefore, it determines the current position of the battery module, generates the corresponding position signal, and transmits the position signal to the connection unit 12. After receiving the position signal, the connection unit 12 immediately transmits the position signal to the communication module 2.

[0072] Furthermore, in order to transmit the location signal to the user terminal, continue as follows Figure 1 As shown, in this embodiment, the communication module 2 includes: an auxiliary unit 21 and a communication unit 22;

[0073] The auxiliary unit 21 is connected to the first positioning module 1 and the communication unit 22, respectively.

[0074] It should be noted that the auxiliary unit 21 mentioned above can be a unit that decodes location information, such as a 4G baseboard, a 5G baseboard, or an IO baseboard. The communication unit 22 mentioned above can be a unit that has the function of communicating with a terminal or user terminal, such as a 4G communication unit, a 5G communication unit, and a Cat series communication unit.

[0075] The auxiliary unit 21 is used to decode the position signal when it receives the position signal and transmit the decoded position signal to the communication unit 22.

[0076] The aforementioned communication unit 22 is used to transmit the decoded position signal to the user terminal.

[0077] In a specific implementation, after receiving the position signal, the auxiliary unit 21 decodes the position signal and transmits the decoded position signal to the communication unit 22. After receiving the decoded position signal, the communication unit 22 transmits the decoded position signal to the user terminal. It should be emphasized that decoding the position signal requires decoding it into a format that the user terminal can receive, so that the user terminal can keep track of the current position of the battery module in real time.

[0078] The positioning circuit in this embodiment may include a first positioning module 1 and a communication module 2. The first positioning module 1 is located inside the battery module and connected to the communication module 2. Firstly, when the first positioning module 1 detects that the current angle signal of the battery module is greater than a preset angle signal, it determines the current position of the battery module, generates a corresponding position signal, and transmits the position signal to the communication module 2. Then, when the communication module 2 receives the position signal, it outputs the position signal to the user terminal. Compared to existing methods, this embodiment can achieve real-time positioning of the battery module through the first positioning module 1 and transmit the position signal to the user terminal, thereby enabling the tracking of lost battery modules.

[0079] Reference Figure 2 , Figure 2 The circuit diagram of the positioning unit in the second embodiment of the positioning circuit proposed in this utility model is shown.

The first ends of the third resistor R3, the fifth resistor R5, and the seventh resistor R7 are all connected to the connection unit 12.

[0083] It should be noted that the gyroscope chip U1 mentioned above can be any chip used to output position signals, such as the QMC5883L gyroscope chip. Of course, other models can also be used, and this embodiment does not limit this. The power supply of the above chip (i.e. Figure 2 The 3.3V1) in the middle can be the power supply required for the operation of the above-mentioned gyroscope chip. It can be obtained by voltage transformation, or it can be obtained by other means. This embodiment does not limit this.

[0084] In a specific implementation, when the gyroscope chip U1 detects that the current angle signal of the battery module is greater than the preset angle signal, it determines the current position of the battery module, generates a corresponding position signal, and transmits the position signal to the connection unit 12 through the data terminal of the gyroscope chip U1.

[0088] It should be noted that the aforementioned connection chip U2 can be any chip used for transmitting position signals, such as the connection chip with model number J_SMT_GYROSCOPE_VW. Of course, other models can also be used, and this embodiment does not limit this.

[0089] In a specific implementation, after receiving the position signal through the second communication terminal of the connection chip U2, the connection chip U2 transmits the position signal to the communication module 2 through the first communication terminal and the second communication terminal of the connection chip U2.

[0099] Reference Figure 6 , Figure 6 This is a schematic diagram of the third embodiment of the positioning circuit proposed in this utility model.

[0100] Based on the above embodiments, a third embodiment of this utility model is proposed. To stop the power supply to each working module within the battery module after the battery module is stolen, such as... Figure 6 As shown, in this embodiment, the positioning circuit further includes a battery management module 3 and a second positioning module 5;

[0101] The battery management module 3 is connected to the second positioning module 5 and each working module 4 in the battery module.

[0102] It should be noted that the battery management module 3 can be any module with battery management functions, such as a centralized BMS (Battery Management System) or a distributed BMS. The working module 4 can be various modules within the battery module that provide services to the base station, such as a storage module, a heat dissipation module, and a temperature detection module. The second positioning module 5 can be a positioning module with the same structure as the first positioning module 1.

[0103] The second positioning module 5 is also used to transmit a power-off signal to the battery management module 3 when the current angle signal of the battery module is detected to be greater than the preset angle signal.

[0104] The battery management module 3 is used to stop supplying power to the working module 4 when it receives the power failure signal.

[0105] In a specific implementation, when the second positioning module 5 detects that the current angle signal of the battery module is greater than the preset angle signal, it determines that the battery module has been stolen. In order to prevent the thief from continuing to use the battery module after stealing it, the battery module triggers a protection mechanism and transmits a power-off signal to the battery management module 3. When the battery management module 3 receives the power-off signal, it immediately stops supplying power to each of the working modules 4 in the battery module, thereby preventing the thief from continuing to use the battery module.

[0106] Furthermore, in order to stop supplying power to each of the working modules 4, such as Figure 7 As shown, Figure 7 This is a circuit diagram of the battery management module in the third embodiment of the positioning circuit proposed in this utility model. In this embodiment, the battery management module 3 includes: a battery management chip U5, a first inductor L1, and a second inductor L2;

[0107] It should be noted that the battery management chip U5 mentioned above can be any chip used to manage the battery power supply function, such as the battery management chip with model number HC32F460PETB. Of course, other models can also be used, and this embodiment does not limit this.

[0108] The first positioning communication terminal of the aforementioned battery management chip U5 (i.e. Figure 7 Pin 79 of the battery management chip U5 is connected to the first terminal of the first inductor L1, and the second positioning communication terminal of the battery management chip U5 (i.e., Figure 7 Pin 78 of the battery management chip U5 is connected to the first terminal of the second inductor L2, and the management terminal of the battery management chip U5 (i.e., Figure 7 The 25th pin of U5 is connected to each of the above-mentioned working modules 4, and the second end of the first inductor and the second end of the second inductor are respectively connected to the second positioning module 5.

[0109] In a specific implementation, the battery management chip U5 receives the power-off signal transmitted by the second positioning module 5 through the first positioning communication terminal and the second positioning communication terminal of the battery management chip U5, and stops supplying power to each of the above-mentioned working modules 4 through the management terminal of the battery management chip U5.
