[0026] Power battery modules are core energy storage devices that provide power for electric vehicles, energy storage systems, etc., and are characterized by high energy density, high power output and long cycle life.

[0027] In the relevant technologies, the power battery module needs to be frequently charged and discharged during use. The power battery module and charger need to be plugged in and unplugged many times during their service life. If the power battery module and charger are not connected correctly, it will affect the charging efficiency of the power battery module and bring safety hazards.

[0028] Based on this, in order to improve the technical problem that the failure of the power battery module and the charger to be properly connected will affect the charging efficiency of the power battery module, the embodiments of this application provide the following solution.

[0029] Please refer to the following: Figure 1 and Figure 2 This application provides a power battery module audible and visual alarm unit 100. The power battery module includes a charging port 200. The power battery module audible and visual alarm unit 100 includes a sliding plate 101 and an audible and visual alarm unit 102. The sliding plate 101 is movable along the axial direction of the charging port 200. The outer side wall of the sliding plate 101 slides and rubs against the inner side wall of the charging port 200. The audible and visual alarm unit 102 is disposed on the outer side of the charging port 200. The audible and visual alarm unit 102 is communicatively connected to the sliding plate 101. The audible and visual alarm is used to emit audible and visual signals according to the state of the sliding plate 101.

[0030] It is understood that the charging port 200 of the power battery module is a component used to connect a charger to provide electrical energy input to the power battery module. The charging port 200 may include multiple sockets and multiple contacts. The depth direction of the sockets is parallel to the axial direction of the charging port 200, and the length direction of the contacts is parallel to the axial direction of the charging port 200. The sliding plate 101 is a component used to move along the axial direction of the charging port 200 to determine the insertion position of the charger. The shape of the sliding plate 101 may be different from the cross-sectional shape of the charging port 200, so that only a portion of the outer wall of the sliding plate 101 slides and rubs against the inner wall of the charging port 200, or the shape of the sliding plate 101 may be the same as the cross-sectional shape of the charging port 200, so that all the outer walls of the sliding plate 101 slide and rub against the inner wall of the charging port 200, but it is not limited to this. The audible and visual alarm unit 102 is a device for emitting audible and visual signals based on the state of the sliding plate 101. The state of the sliding plate 101 includes its position within the charging port 200 and the offset of its axis relative to the axis of the charging port 200. The audible and visual alarm unit 102 may include a state acquisition module and an audible and visual alarm module. The state acquisition module is used to acquire the state of the sliding plate 101, and may be a camera or an infrared rangefinder, but is not limited to these. The audible and visual alarm module is used to emit audible and visual signals, and may include a buzzer or horn, a fluorescent lamp or a light-emitting diode, but is not limited to these.

[0031] As can be seen from the above, the power battery module audible and visual alarm unit 100 provided in this application embodiment is equipped with a sliding plate 101 that can move along the axial direction of the charging port 200. The audible and visual alarm unit 102 monitors the state of the sliding plate 101 within the charging port 200, and then emits an audible and visual signal that reflects the state of the sliding plate 101 within the charging port 200. In this way, real-time monitoring and early warning of the connection status between the charger and the charging port 200 can be realized, effectively avoiding dangers caused by improper connection, reducing damage to the charging port 200 and the power battery caused by improper connection, extending the service life of the charging port 200 and the power battery, and reducing the maintenance costs of the charging port 200 and the power battery.

[0032] In some embodiments, please refer to the following: Figures 1 to 3The power battery module also includes a movable guide rail 203; the movable guide rail is disposed on the inner side wall of the charging port 200; the length direction of the movable guide rail is parallel to the axial direction of the charging port 200; the sliding plate 101 is movably disposed on the movable guide rail; the charging port 200 has an opening 201; the audible and visual alarm unit 102 includes a light strip 1021, which is disposed on the outer side of the charging port 200; the length direction of the light strip 1021 is parallel to the axial direction of the charging port 200; the light strip 1021 is electrically connected to the movable guide rail; the length of the light strip 1021 is less than the length of the movable guide rail; one end of the light strip 1021 away from the opening 201 of the charging port 200 is aligned with one end of the movable guide rail away from the opening 201 of the charging port 200 along the axial direction of the charging port 200; wherein, the light strip 1021 can light up in segments along its own length direction; the light strip 1021 is used to light up in segments according to the position change of the sliding plate 101 on the movable guide rail 203.

[0033] It is understood that the movable guide rail 203 can be a groove formed on the inner wall of the charging port 200 along the axial direction of the charging port 200, or the movable guide rail 203 can be two linear guide rails arranged on the inner wall of the charging port 200 along the axial direction of the charging port 200, but is not limited to these. The charging port 200 has an opening 201 to allow the charger to be inserted and connected. The light strip 1021 is a component in the audible and visual alarm unit 102 used to emit light signals. The light strip 1021 is disposed on the outer surface of the charging port 200 facing the user, for example, it can be the upper part or the lower part, but is not limited to these. The light strip 1021 can be a single-color light strip 1021 or a multi-color light strip 1021, but is not limited to these. The length of the light strip 1021 is less than the length of the moving guide rail, and the end of the light strip 1021 away from the opening 201 of the charging port 200 is aligned with the end of the moving guide rail away from the opening 201 of the charging port 200 along the axial direction of the charging port 200, so that the light strip 1021 will not light up when the sliding plate 101 is located at one end of the opening 201 of the charging port 200. The light strip 1021 may include a programmable controller and multiple addressable LEDs, with each addressable LED controlled to light up individually by the programmable controller, or the light strip 1021 may include multiple LEDs and a multi-channel controller, with multiple channels controlling multiple LEDs to light up individually, but is not limited to this.

[0034] With this configuration, a movable guide rail 203 is provided on the inner wall of the charging port 200 along the axial direction of the charging port 200, allowing the sliding plate 101 to move along the length of the movable guide rail 203. A light strip 1021 is provided on the outer side of the charging port 200 along the axial direction of the charging port 200. The length of the light strip 1021 is less than the length of the movable guide rail 203, so that the light strip 1021 will not light up when the charger is not inserted into the charging port 200. Furthermore, the light strip 1021 can light up in segments according to the position change of the sliding plate 101 on the movable guide rail 203, which is beneficial for visual feedback on the connection status of the charger and the charging port 200, timely reminders of improper operation, reduction of the risk of arcing or short circuit caused by incomplete insertion, reduction of damage to the charging port 200 and the power battery due to improper connection, extension of the service life of the charging port 200 and the power battery, and reduction of the maintenance cost of the charging port 200 and the power battery.

[0035] In some embodiments, please refer to Figures 1 to 3 The light strip 1021 includes a power supply 10211, two electrode strips 10212, and multiple LED beads 10213. The power supply 10211 is disposed on the outer wall of the charging port 200. The two electrode strips 10212 are disposed opposite to each other and spaced apart on the moving guide rail. The two electrode strips 10212 are connected to the two poles of the power supply 10211 in a one-to-one correspondence. The multiple LED beads 10213 are disposed on the outer wall of the charging port 200 along the axial direction of the charging port 200. One pole of the LED bead 10213 is electrically connected to one electrode strip 10212.

[0036] The sliding plate 101 includes a brush 1011, the two ends of which are detachably abutted against two electrode strips 10212 respectively; the brush 1011 is used to move along the length direction of the moving guide rail 203 and electrically connect the other pole of one lamp bead 10213 to the other electrode strip 10212.

[0037] It is understood that the power supply 10211 is a component used to independently provide electrical energy. It can be an AC power supply 10211 or a DC power supply 10211, a high-voltage power supply 10211 or a low-voltage power supply 10211, depending on the needs of the electrical equipment. The electrode strip 10212 is a component that combines electrodes with flexible strip material, used to connect the power supply 10211 to the LED chip 10213. The electrode strip 10212 can be a metal electrode strip 10212, such as a copper sheet or iron sheet, or a carbon fiber electrode strip 10212, but is not limited to these. The LED chip 10213 is a light-emitting element. The LED chip 10213 has two electrodes. Electrically connecting the two electrodes to the two poles of the power supply 10211 will cause the LED chip 10213 to light up.

[0038] The brush 1011 is a component used to electrically connect the two electrode strips 10212, thereby connecting the two electrodes of the lamp bead 10213 to the two poles of the power supply 10211 respectively. The brush 1011 can be square or T-shaped, but is not limited to these shapes. The material of the brush 1011 can be electrographite, or conductive metals such as copper or silver, but is not limited to these materials.

[0039] With this configuration, a power supply 10211 is installed on the outer wall of the charging port 200, and two electrode strips 10212 are respectively placed on the moving guide rail. When the sliding plate 101 moves along the length of the moving guide rail 203, the brush 1011 can move along the moving guide rail 203, changing the position connected to the two electrode strips 10212, thereby connecting the two poles of the LED bead 10213 at that position to the power supply 10211 and lighting up the LED bead 10213. The position of the sliding plate 101 is made visible through the mechanical structure, making it easy to detect problems with improper insertion and connection of the charging gun in a timely manner, avoiding charging interruption or damage to the battery module due to connection problems, and reducing the maintenance cost and repair frequency of the power battery module.

[0040] In some embodiments, the LED 10213 can emit light signals of different colors.

[0041] It is understandable that light signals can have multiple colors. Light signals can be adjusted to different on / off frequencies. Light signals can be adjusted to different brightness levels.

[0042] This configuration enables the LED 10213 to emit light signals of different colors, different on / off frequencies, and different brightness, thereby improving the adaptability of the audible and visual alarm device. It allows the device to emit different signals based on the different states of the sliding plate 101 and the charger, reducing false alarms and missed alarms, and improving the accuracy of alarm information.

[0043] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The charging port 200 has a groove 202 around its own axis; the audible and visual alarm device also includes a water-absorbing expansion member 1022 and a first pressure sensor 1023. The water-absorbing expansion member 1022 is disposed in the groove 202; the water-absorbing expansion member 1022 can expand or shrink along the depth direction of the groove 202; the first pressure sensor 1023 is disposed at the bottom of the groove 202; the first pressure sensor 1023 is communicatively connected to the audible and visual alarm unit 102; wherein, the water-absorbing expansion member 1022 can expand to abut against the first pressure sensor 1023.

[0044] It is understood that the water-absorbing expansion component 1022 is a component that can expand as the humidity inside the charging port 200 increases. The water-absorbing expansion component 1022 can be a ring disposed within the groove 202; it can also be multiple arc segments, evenly and spaced apart within the groove 202, but is not limited to these. The water-absorbing expansion component 1022 can be made of highly absorbent resin or water-absorbing and expanding rubber, but is not limited to these. The first pressure sensor 1023 is a component used to contact the water-absorbing expansion component 1022 to detect the magnitude of the pressure exerted by the water-absorbing expansion component 1022. The first pressure sensor 1023 can be a strain gauge pressure sensor or a piezoresistive pressure sensor, but is not limited to these. The first pressure sensor 1023 is communicatively connected to the audible and visual alarm unit 102, so that the audible and visual alarm unit 102 can issue a corresponding audible and visual alarm signal based on the pressure signal from the first pressure sensor 1023.

[0045] With this configuration, a groove 202 is formed on the inner wall of the charging port 200 around its axis. The water-absorbing expansion member 1022 is placed in the groove 202, and the first pressure sensor 1023 is placed at the bottom of the groove 202. When the humidity inside the charging port 200 increases or water enters the charging port 200, the water-absorbing expansion member 1022 can absorb water and expand until it comes into contact with the first pressure sensor 1023. Then, the audible and visual alarm unit 102 emits an audible and visual alarm signal based on the pressure signal from the first pressure sensor 1023. This can provide an audible and visual warning to the user when the humidity inside the charging port 200 is high or water enters the charging port 200, thereby improving the sensitivity of the charging port 200 to internal moisture detection, effectively avoiding electrical faults, reducing the risk of damage to the charging port 200 or the battery, and improving the reliability of the power battery module.

[0046] In some embodiments, please refer to Figure 3 and Figure 4 The water-absorbing expansion member 1022 can expand to protrude from the groove 202; the audible and visual alarm device also includes a second pressure sensor 1024, which is disposed in the groove 202 on the side away from the opening 201; the second pressure sensor 1024 is communicatively connected to the audible and visual alarm unit 102; the second pressure sensor 1024 is used to detect the pressure on the water-absorbing expansion member 1022 along the axial direction of the charging port 200.

[0047] It is understood that the groove 202 is formed within the charging port 200 near the opening 201, and the water-absorbing expansion member 1022 can expand along the depth direction of the groove 202 to partially protrude from the groove 202. The second pressure sensor 1024 is a component used to detect the pressure exerted on the water-absorbing expansion member 1022 along the axial direction of the charging port 200. The second pressure sensor 1024 can use the same element as the first pressure sensor 1023. The audible and visual alarm unit 102 can emit a corresponding audible and visual alarm signal based on the pressure signal from the second pressure sensor 1024.

[0048] This configuration allows the water-absorbing expansion member 1022 to absorb water and expand until it protrudes from the groove 202, thereby preventing the sliding plate 101 from moving along the axis of the charging port 200. When the humidity inside the charging port 200 is high or water has entered, the charger cannot enter the charging port 200 to establish an electrical connection. Furthermore, when the charger pushes the sliding plate 101 along the axis of the charging port 200, the water-absorbing expansion member 1022 protrudes from the groove 202, increasing the pressure on the second pressure sensor 1024. This allows the audible and visual alarm unit 102 to issue a corresponding audible and visual alarm based on the pressure signal from the second pressure sensor 1024, prompting the user to stop the current erroneous operation. This effectively avoids electrical faults, reduces the risk of damage to the charging port 200 or the battery, extends the lifespan of the charging port 200 and the power battery, and reduces the maintenance costs of the charging port 200 and the power battery.

[0049] In some embodiments, please refer to Figure 1 and Figure 2 The sliding plate 101 includes a plate body 1012 and a plurality of third pressure sensors 1013. The plate body 1012 is movable along the axial direction of the charging port 200. The axial direction of the plate body 1012 is collinear with the axial direction of the charging port 200. The outer side wall of the plate body 1012 slides and rubs against the inner side wall of the charging port 200. The plurality of third pressure sensors 1013 are evenly and spaced apart on the outer side of the plate body 1012. The third pressure sensors 1013 are communicatively connected to the audible and visual alarm unit 102. The third pressure sensors 1013 are used to detect the pressure on the plate body 1012 in the direction perpendicular to its own axis.

[0050] It is understood that the third pressure sensor 1013 is used to detect the pressure on the sliding plate 101 in a direction perpendicular to its own axis. The third pressure sensor 1013 can use the same components as the first pressure sensor 1023.

[0051] With this configuration, multiple third pressure sensors 1013 are evenly and spaced apart on the outer wall of the plate 1012 around its axis. When the charger or charging port 200's socket or contact is tilted, or when there is debris in the charging port 200, when the charger is inserted into the charging port 200 and the sliding plate 101 is moved, the sliding plate 101 will be subjected to pressure from the tilted socket or contact, or the debris, in a direction perpendicular to the axis of the sliding plate 101. This causes the third pressure sensors 1013 to generate pressure signals. The audible and visual alarm unit 102 then issues an audible and visual alarm signal based on the pressure signal from the third pressure sensor 1013, promptly reminding the user to avoid further contact with the tilted socket or contact, and to prevent interface damage or poor contact caused by tilted insertion or removal of the charger or charging port 200. This protects the structural and functional integrity of the charging interface and extends the service life of the charging port 200 and the power battery.

[0052] In some embodiments, please refer to Figure 1 and Figure 3 The sound and light alarm unit 102 includes a control device 1025, a sound alarm 1026, and a light signal collector 1027. The control device 1025 is located on the outer side of the charging port 200 and is electrically connected to the light strip 1021. The sound alarm 1026 is located on the outer side of the charging port 200 and is electrically connected to the control device 1025. The sound alarm 1026 can emit various sound signals. The light signal collector 1027 is located on one side of the light strip 1021 and is electrically connected to the control device 1025. The light signal collector 1027 is used to collect the light signal of the light strip 1021. The control device 1025 is used to adjust the sound signal of the sound alarm 1026 and the light signal of the light strip 1021 according to the light signal collected by the light signal collector 1027.

[0053] It is understood that the control device 1025 is a device for receiving signals, processing and analyzing signals, and emitting signals. The control device 1025 may include a microcontroller or a CPU, but is not limited to these. The sound alarm 1026 is a component for emitting sound signals to alert the user, such as a buzzer or an electronic speaker, but is not limited to these. The light signal collector 1027 is a device for collecting light signals emitted by the light strip 1021, such as a camera or a spectrometer, but is not limited to these.

[0054] With this configuration, a control device 1025, a sound alarm 1026, and a light signal collector 1027 are installed on the outer side of the charging port 200. The sound alarm 1026 emits an audible signal, and the light signal collector 1027 collects the light signal emitted by the light strip 1021. The control device 1025 adjusts the light signal according to the audible signal and the audible signal according to the light signal, so that the audible and visual alarm unit 102 can achieve synchronous audible and visual alarm. It also adjusts the audible and visual signals according to feedback, so that the audible and visual signals can transmit the common information of both, improve the alarm effect, and enhance the reliability of the audible and visual alarm unit 102.

[0055] Optionally, in some embodiments, please refer to Figure 1 and Figure 3 The power battery module audible and visual alarm unit 100 also includes a reset device 103. One end of the reset device 103 is located on the side of the sliding plate 101 away from the opening 201 of the charging port 200; the other end of the reset device 103 is located on the bottom surface of the charging port 200.

[0056] It is understood that the reset device 103 is used to enable the sliding plate 101 to move towards the side of the charging port 200 near the opening 201 as the charger leaves the charging port 200, ensuring that the sliding plate 101 remains in contact with the charger. The reset device 103 may be a spring 1031, or may include a slide rail and an electric slide. The slide rail is disposed on the inner side of the charging port 200, with one end of the slide rail disposed on the side of the sliding plate 101 away from the opening 201 of the charging port 200, and the other end of the slide rail disposed on the bottom surface of the charging port 200. The electric slide is located between the sliding plate 101 and the bottom surface of the charging port 200, and the electric slide can move to push the sliding plate 101 towards the side of the charging port 200 near the opening 201, but is not limited to this.

[0057] With this configuration, a reset device 103 is provided on the side of the sliding plate 101 away from the opening 201 of the charging port 200, so that the sliding plate 101 can always be in contact with the charger. When the charger is removed from the charging port 200, the sliding plate 101 can be located inside the charging port 200 near the opening 201. This can reflect the position of the charger in real time and accurately, improve the accuracy and reliability of the audible and visual alarm device, effectively prevent foreign objects from entering the charging port 200, protect the structural and functional integrity of the charging interface, and extend the service life of the charging port 200 and the power battery.

[0058] Optionally, in some embodiments, please refer to Figure 1 and Figure 3The reset device 103 includes a plurality of springs 1031. One end of each spring 1031 is disposed on the side of the sliding plate 101 away from the opening 201 of the charging port 200. The other end of each spring 1031 is disposed on the bottom surface of the charging port 200. The plurality of springs 1031 are spaced apart. The plurality of springs 1031 have the same length.

[0059] It is understandable that multiple springs 1031 have the same length, and each spring 1031 generates the same elastic force when compressed to the same length. When the pressure on the side of the sliding plate 101 is uneven, the sliding plate 101 will tilt and will not be able to continue moving along the axis of the charging port 200.

[0060] With this configuration, multiple springs 1031 abut against the sliding plate 101, causing the sliding plate 101 to tilt when subjected to uneven pressure, preventing it from continuing to move along the axis of the charging port 200. This prevents objects whose shape does not match the charging port 200 from entering the charging port 200, avoids damage to the interface of the charging port 200, protects the structural and functional integrity of the charging interface, and extends the service life of the charging port 200 and the power battery.

[0061] Please see Figure 5 This application also provides a control method for a power battery module audible and visual alarm unit. The control method for the power battery module audible and visual alarm unit provided in this application is applied to the power battery module audible and visual alarm unit 100 as described in any of the above embodiments. At this time, the power battery module audible and visual alarm unit 100 is the executing subject of the control method for the power battery module audible and visual alarm unit provided in this application. This application does not impose any limitations on the power battery module audible and visual alarm unit 100.

[0062] For example, please see Figure 1 The power battery module audible and visual alarm unit 100 may include a sliding plate 101 and an audible and visual alarm unit 102. The sliding plate 101 is movable along the axis of the charging port 200. The outer side wall of the sliding plate 101 slides and rubs against the inner side wall of the charging port 200. The audible and visual alarm unit 102 is disposed on the outer side of the charging port 200. The audible and visual alarm unit 102 is communicatively connected to the sliding plate 101. The audible and visual alarm is used to emit audible and visual signals according to the position of the sliding plate 101. The audible and visual alarm unit 102 includes a control device 1025. The control device 1025 may be a microcontroller, PLC, central processing unit, handheld device with wireless communication function, computing device, or other processing device connected to a wireless modem.

[0063] To better understand the control method of the power battery module audible and visual alarm unit provided in the embodiments of this application, the specific implementation process of the control method of the power battery module audible and visual alarm unit provided in the embodiments of this application will be described by way of example below.

[0064] Figure 5 A schematic flowchart of a control method for a power battery module audible and visual alarm unit provided in an embodiment of this application is shown. The control method for the power battery module audible and visual alarm unit includes: S100, acquire the first optical signal.

[0065] It can be understood that the first light signal is emitted by the light emitted when the brush 1011 on the sliding plate 101 moves to different positions on the moving guide rail 203, causing the lamp bead 10213 at that position to light up. The first light signal includes the position information of the sliding plate 101.

[0066] S200, acquire pressure data.

[0067] It is understood that the pressure data includes first pressure data, second pressure data, and third pressure data. The first pressure data is acquired by the first pressure sensor 1023 and reflects the degree of expansion of the water-absorbing expansion member 1022, i.e., the humidity within the charging port 200. The second pressure data is acquired by the second pressure sensor 1024 and reflects the pressure exerted on the water-absorbing expansion member 1022 along the axis of the charging port 200, i.e., the user forcibly inserts the charger into the charging port 200 even when the humidity within the charging port 200 is high. The third pressure data is acquired by the third pressure sensor 1013 and reflects the pressure exerted on the plate 1012 perpendicular to its own axis, i.e., the user inserts the charger into the charging port 200 at an angle, or the user inserts an incompatible charger into the charging port 200, or there are foreign objects within the charging port 200, but not limited to these.

[0068] S300, based on the pressure data, controls the power battery module audible and visual alarm unit 100 to emit the first sound signal.

[0069] It is understandable that, based on the state of the charging port 200 and the sliding plate 101 reflected by the first pressure data, the second pressure data, and the third pressure data, a first sound signal is emitted. For example, the first sound signal can be a "buzzing sound, 1 time / second, volume 20%"; or it can be a voice alarm with the content "charging port 200 is damp" with a broadcast interval of 2 seconds and a volume of 30%; or it can be no alarm and remain silent, but it is not limited to these.

[0070] S400 adjusts the first sound signal to the second sound signal based on the first light signal.

[0071] It is understood that the first optical signal includes the position information of the sliding plate 101. Based on the position information of the sliding plate 101, the sound frequency and sound amplitude of the first sound signal can be changed, or the alarm content of the first sound signal can be changed, but not limited to these.

[0072] S500 adjusts the first optical signal to the second optical signal based on the first acoustic signal.

[0073] It is understood that the first sound signal reflects the internal state of the charging port 200, including the internal humidity, the presence of debris, and the insertion posture of the charger. Based on the internal state of the charging port 200, the on / off frequency of the first light signal, the brightness of the LED 10213, or the color of the LED 10213 can be changed, but not limited to these.

[0074] As can be seen from the above, the control method of the power battery module audible and visual alarm unit provided in this application embodiment moves the sliding plate 101 within the charging port 200 to cause the LED bead 10213 to emit a first light signal. The audible and visual alarm unit 102 emits a first sound signal according to the internal state of the charging port 200. The control device 1025 adjusts the first light signal to a second light signal and the first sound signal to a second sound signal according to the first sound signal. Through the mutual feedback between the first light signal and the first sound signal, both the second light signal and the second sound signal can completely reflect the state of the charger and the sliding plate 101 within the charging port 200. In this way, real-time monitoring and dynamic feedback of the charging port 200 can be achieved, improving the accuracy and reliability of the alarm, enriching the alarm content, and facilitating fault diagnosis and maintenance.

[0075] As an optional embodiment of this application, the pressure data includes longitudinal pressure data and lateral pressure data; S300, based on the pressure data, control the power battery module audible and visual alarm unit 100 to emit a first audible signal, including: S310, frequency data is obtained based on longitudinal pressure data.

[0076] It can be understood that the longitudinal pressure data is the pressure parallel to the axis of the charging port 200, and the longitudinal pressure data may include the second pressure data. The frequency data is the vibration frequency of the sound; the higher the frequency data, the sharper the sound emitted by the audible and visual alarm device. The frequency data is increased based on the increase in the second pressure data.

[0077] S320, based on the lateral pressure data, obtain the amplitude data.

[0078] It can be understood that the lateral pressure data refers to the pressure perpendicular to the 200-degree axis of the charging port, and this lateral pressure data may include third-party pressure data. The amplitude data represents the magnitude of the sound amplitude; the larger the amplitude data, the louder the sound and light alarm. Based on the increase in lateral pressure data, the amplitude data is increased accordingly. S330 controls the power battery module's audible and visual alarm unit 100 to emit the first sound signal based on frequency and amplitude data.

[0079] With this configuration, the control device 1025 controls the power battery module's audible and visual alarm unit 100 to emit a first sound signal based on frequency and amplitude data. In this way, the first sound signal can transmit information including the magnitude of the pressure on the water-absorbing expansion member 1022 along the axis of the charging port 200 and the magnitude of the pressure on the plate 1012 perpendicular to its own axis. This allows the user to have a more comprehensive understanding of the specific situation inside the charging port 200, enhancing the system's adaptability and flexibility, avoiding misjudgments caused by limited information, and enabling timely implementation of appropriate measures to prevent further escalation of the fault.
