Description

Technical Field

[0001] This application relates to the field of headphone technology, and in particular to a charging method for an earphone charging case, an earphone charging case, and a storage medium. Background Technology

[0002] With the development and advancement of technology, electronic products are constantly being updated and iterated to meet people's needs. Furthermore, as people's awareness of their surroundings improves, they are becoming increasingly mindful of the volume of electronic devices in public places. To avoid disturbing others with loudspeakers, many people choose to wear headphones. Due to the long and cumbersome cables of wired headphones, wireless headphones have emerged as a popular choice. Wireless headphones come with a charging case and two earbuds, making them convenient to use anytime.

[0003] Currently, when users charge earbuds using the charging case, the output current of the charging case is often fixed. This fixed output current causes the charging case's temperature to rise continuously with charging time, potentially affecting the battery life. Sometimes, the temperature reaches the charging case's over-temperature protection point, causing it to cut off power and stop charging the earbuds, thus affecting their use. Summary of the Invention

[0004] This application provides a charging method for an earphone charging case, an earphone charging case, and a storage medium.

[0005] Firstly, this application provides a charging method for an earphone charging case.

[0006] Get the temperature of the earphone charging case while it is charging; The temperature is compared with a preset charging temperature threshold to determine whether the temperature is higher than the charging temperature threshold. If the temperature is higher than the charging temperature threshold, then the temperature level corresponding to the temperature is determined according to a preset temperature level; the preset temperature level includes several temperature levels; each temperature level is matched with a corresponding available current; Adjust the current at the current moment according to the available current corresponding to the temperature level.

[0007] The charging method for the earphone charging case provided in this embodiment can adjust the current level in a timely manner when the temperature of the earphone charging case becomes high due to the increase in charging time. This slows down the rate of temperature increase, reduces damage to the components of the earphone charging case, and thus protects the battery and other components inside the earphone charging case, extending the service life of the earphone charging case.

[0008] Optionally, the method further includes: After the earphone charging case is charged using the available current, the temperature change after adjustment is obtained; Based on the changes, determine whether the changed temperature is lower than the charging temperature threshold. If the changed temperature is lower than the charging temperature threshold, the available current is adjusted to the initial current to charge the headphones.

[0009] The charging method for the earphone charging case provided in this embodiment can adjust the current level in a timely manner when the temperature of the earphone charging case becomes high due to the increase in charging time. This slows down the rate of temperature increase, reduces damage to the components of the earphone charging case, and thus protects the battery and other components inside the earphone charging case, extending the service life of the earphone charging case.

[0010] Optionally, the method further includes: After the earphone charging case is charged using the available current, the temperature change after adjustment is obtained; Based on the changes, determine whether the changed temperature is lower than the charging temperature threshold. If the changed temperature is lower than the charging temperature threshold, the available current is adjusted to the initial current to charge the headphones.

[0011] The method provided in this embodiment addresses the issue that when the earphone charging case temperature is below the charging temperature threshold, the required electrical energy decreases as the earphone battery level increases. However, the electrical energy generated by charging the earphones using the same current remains constant. Therefore, more of the electrical energy generated by the current is wasted, potentially leading to more energy being converted into heat, thus raising the charging case temperature. Therefore, by matching the earphone's battery level to the appropriate current for charging, excess electrical energy can be prevented from being converted into heat as the earphone battery level increases, thus extending the charging case's lifespan.

[0012] Optionally, the method further includes: If the temperature is higher than the charging temperature threshold, the heat generated by the temperature is dissipated using a water-cooling heat dissipation device according to a preset setting. Based on the dissipation situation, the temperature after dissipation is compared with the charging temperature threshold, and the current is adjusted according to the comparison result.

[0013] The method described in this embodiment allows for timely absorption and dissipation of heat using a water-cooling device when the temperature rises, thus lowering the temperature. Furthermore, it adjusts the current promptly after temperature changes to prevent secondary heating, thereby protecting the earphone charging case and extending its lifespan.

[0014] Optionally, the method further includes: When the heat generated by the temperature is dissipated by the water cooling device within a preset time period, and the earphone is charged according to the available current, if the temperature after heat dissipation is higher than the charging temperature threshold, the battery health value of the earphone charging case is obtained. Based on a preset battery health threshold, determine whether the battery health value of the earphone charging case is lower than the preset battery health threshold; If the battery health value is lower than the preset battery health threshold, a maintenance reminder instruction is sent to the terminal device so that the user can perform maintenance in a timely manner.

[0015] In this embodiment, if the temperature remains above the charging temperature threshold or continues to rise after the water-cooling device dissipates heat and the current is adjusted to a usable level for charging the earphones for a period of time, it may indicate that the earphones in the charging case are severely worn and unable to provide adequate power. Instead, they are converting a significant portion of the electrical energy generated by the current into heat, requiring timely maintenance. To determine this, the battery health value of the earphone charging case can be obtained and it can be determined whether the battery health value is below a preset battery health threshold. This allows for timely sending of a maintenance reminder to the terminal device when the battery is severely worn and requires maintenance, preventing a poor user experience caused by the earphone charging case being unable to charge the earphones without the user's knowledge.

[0016] Optionally, the method further includes: Obtain the battery level of the earphone charging case; The battery level is compared with a first preset power threshold to determine whether the battery level is lower than the first preset power threshold. If the battery level is lower than the first preset power threshold, power supply to the headphones will stop.

[0017] The method provided in this embodiment can stop supplying power to the earphones in a timely manner when the battery of the earphone charging case is low, avoiding the loss caused by the battery continuing to charge the earphones when the battery is low, thereby extending the battery life of the earphone charging case.

[0018] Optionally, the method further includes: If the battery level is lower than the first preset power threshold, then the power level of the earphone is obtained, and it is determined whether the power level of the earphone is higher than the second preset power threshold. If the battery level of the earphones is lower than the second preset battery threshold, then when the charging case is connected to an external power source, the current generated by the external power source will be used to charge the earphones.

[0019] The method provided in this embodiment can determine whether the earphone's battery level is higher than a second preset battery threshold when the earphone charging case battery needs to be charged. If it is lower than the second preset battery threshold, the earphone will be charged first when it is placed in the earphone charging case and connected to an external power source. This ensures that users do not have to worry about the earphone's battery not being able to support the earphone until the earphone charging case battery is fully charged, thus improving the user experience.

[0020] Secondly, this application provides an earphone charging case, comprising: Temperature acquisition module, used to acquire the temperature of the earphone charging case during charging; A temperature comparison module is used to compare the temperature with a preset charging temperature threshold to determine whether the temperature is higher than the charging temperature threshold. The temperature level determination module is used to determine the temperature level corresponding to the temperature according to a preset temperature level if the temperature is higher than the charging temperature threshold; the preset temperature level includes several temperature levels; each temperature level is matched with a corresponding available current. The current adjustment module is used to adjust the current at the current moment according to the available current corresponding to the temperature level.

[0021] Optionally, the earphone charging case further includes a current recovery module for: After the earphone charging case is charged according to the available current, the temperature change after adjustment is obtained; Based on the changes, determine whether the changed temperature is lower than the charging temperature threshold. If the changed temperature is lower than the charging temperature threshold, the available current is adjusted to the initial current to charge the headphones.

[0022] Optionally, the earphone charging case further includes an applicable current adjustment module for: If the temperature is lower than the charging temperature threshold, then the battery level of the earphone is obtained; The battery level is matched with the battery level corresponding to a preset battery level to determine the current battery level of the headphones; the preset battery level includes several battery levels; each battery level is matched with a corresponding applicable current. Based on the applicable current corresponding to the preset power level, determine the optimal applicable current at the current moment and charge the earphones according to the optimal applicable current.

[0023] Optionally, the earphone charging case further includes a heat dissipation module for: If the temperature is higher than the charging temperature threshold, the heat generated by the temperature will be dissipated according to the preset water cooling heat dissipation device. Based on the dissipation situation, the temperature after dissipation is compared with the charging temperature threshold, and the current is adjusted according to the comparison result.

[0024] Optionally, the earphone charging case also includes a maintenance reminder module for: When the heat generated by the temperature is dissipated by the water cooling device within a preset time period, and the earphone is charged according to the available current, if the temperature after heat dissipation is higher than the charging temperature threshold, the battery health value of the earphone charging case is obtained. Based on a preset battery health threshold, determine whether the battery health value of the earphone charging case is lower than the preset battery health threshold; If the battery health value is lower than the preset battery health threshold, a maintenance reminder instruction is sent to the terminal device so that the user can perform maintenance in a timely manner.

[0025] Optionally, the earphone charging case further includes a power-off module for: Obtain the battery level of the earphone charging case; The battery level is compared with a first preset power threshold to determine whether the battery level is lower than the first preset power threshold. If the battery level is lower than the first preset power threshold, power supply to the headphones will stop.

[0026] Optionally, the earphone charging case further includes a charging module for: If the battery level is lower than the first preset power threshold, then the power level of the earphone is obtained, and it is determined whether the power level of the earphone is higher than the second preset power threshold. If the battery level of the earphones is lower than the second preset battery threshold, then when the charging case is connected to an external power source, the current generated by the external power source will be used to charge the earphones.

[0027] Thirdly, this application provides an earphone charging case, including: a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute the method of the first aspect.

[0028] Fourthly, this application provides a computer-readable storage medium storing a computer program that can be loaded by a processor and execute the method of the first aspect. Attached Figure Description

[0033] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0034] When users charge their earbuds using the charging case, the case's output current is often fixed. This fixed output current causes the charging case's temperature to rise continuously with charging time, potentially affecting the battery's lifespan. Sometimes, the temperature reaches the charging case's over-temperature protection point, causing it to cut off power and stop charging the earbuds, thus affecting their normal use.

[0035] Based on this, this application provides a charging method for an earphone charging case, an earphone charging case, and a storage medium. When the earphone charging case is charging the earphones, the temperature of the earphone charging case is acquired and compared with a preset charging temperature threshold. If the temperature is higher than the charging temperature threshold, the temperature level corresponding to this temperature and the available current corresponding to that temperature level can be determined according to a preset temperature level and adjusted accordingly. The method of this application can adjust the charging current when the temperature of the earphone charging case rises, thus avoiding a rapid increase in temperature. Simultaneously, it can also minimize the problem of the temperature rapidly reaching the over-temperature protection point, thereby extending the battery life of the earphone charging case.

[0036] Figure 1 This is a schematic diagram illustrating an application scenario provided by this application. The earphone charging case's mainboard incorporates a thermistor that continuously monitors the temperature of the area generating heat within the charging case. The charging case receives the temperature monitored by the thermistor, and when the temperature reaches a charging temperature threshold, it adjusts the output current according to the corresponding temperature level, using available current to prevent rapid temperature increases due to high output current.

[0037] For specific implementation details, please refer to the following examples.

[0038] Figure 2 This is a flowchart illustrating a charging method for an earphone charging case according to an embodiment of this application. The method of this embodiment can be applied to earphone charging cases in the above-described scenarios. Figure 2 As shown, the method includes: S201. Obtain the temperature of the earphone charging case during charging.

[0039] Currently, most earphones require sufficient power to function properly. Therefore, wireless earphones typically include a charging case that powers the earphones, allowing them to recharge using the battery stored in the case when the earphones are out of power. When the charging case is charging the earphones, it converts the electrical energy from the battery in the case into electrical energy for the earphones, storing it within the earphones to enable them to function. However, during this conversion process, some energy is lost as heat, which may cause the charging case to heat up.

[0040] Specifically, when the earphone charging case is charging the earphones, the temperature of the location where the earphone charging case outputs current and the surrounding components will increase as the charging time increases. It should be noted that, generally speaking, the temperature of the location where the output current is located will be higher than the temperature of other locations. Therefore, the temperature of the location where the output current is located can be obtained in real time as the temperature of the earphone charging case when charging the earphones.

[0041] S202. Compare the temperature with the preset charging temperature threshold to determine whether the temperature is higher than the charging temperature threshold.

[0042] Whether it's an earphone charging case or other charging devices, manufacturers often incorporate over-temperature protection features during production to protect the components. This over-temperature protection sets an upper limit on the temperature. When the internal temperature of these devices rises abnormally, the over-temperature protection is activated. This protection can be achieved by cutting off the power to stop the device from operating, protecting the earphone charging case and preventing the internal components from burning out due to overheating. However, by the time the over-temperature protection point is reached, damage may have already occurred to the internal components. Therefore, in the method of this application, an additional charging temperature threshold can be set. This threshold's maximum temperature will not damage the device's components, or may cause negligible minor damage.

[0043] The preset charging temperature threshold can be set based on the degree of damage different temperatures cause to the earphone charging case's battery. For example, when the temperature is between 20°C and 30°C, using the earphone charging case's battery and a fixed output current to charge the earphones will not damage the battery. When the temperature is between 30°C and 40°C, using the earphone charging case's battery and a fixed output current to charge the earphones will cause slight damage to the battery, but the impact is negligible. However, when the temperature is above 41°C, using the earphone charging case's battery and a fixed output current to charge the earphones may cause some damage to the battery, and may even reach the over-temperature protection point during continuous temperature rise, causing the earphone charging case to shut down. Therefore, the temperature that will not damage the battery, i.e., 30°C as mentioned in the above example, can be used as the charging temperature threshold.

[0044] It should be noted that the figures mentioned above are for illustrative purposes only and do not affect the method described in this application. Manufacturers and operators can set these figures according to the characteristics of their respective products; this application does not impose any restrictions.

[0045] Specifically, after comparing the temperature obtained in step S201 with the preset charging temperature threshold, it is determined whether the temperature obtained at the current moment is higher than the charging temperature threshold, thereby determining whether the current needs to be adjusted at the current moment to avoid the temperature from continuing to rise.

[0046] S203. If the temperature is higher than the charging temperature threshold, the temperature level corresponding to the temperature is determined according to the preset temperature level; the preset temperature level includes several temperature levels; any temperature level is matched with the corresponding available current.

[0047] In some implementations, the impact of temperature on the earphone charging case can be represented by temperature levels. Therefore, preset temperature levels can be set. For example, four preset temperature levels can be set: A, B, C, and D. The higher the level, the greater the impact of the corresponding temperature on earphone charging, and the greater the potential damage to the charging case. For example, level A represents a low temperature, level B represents a moderate temperature, level C represents a high temperature, and level D represents an excessively high temperature. Different temperature levels correspond to a suitable current for charging the earphones, i.e., the available current. The higher the temperature level, the lower the available current. As the temperature level changes from high to low, the corresponding available current increases.

[0048] Specifically, if it is determined that the temperature is higher than the charging temperature threshold according to step S202 above, a temperature level matching the current temperature is determined according to the preset temperature level.

[0049] S204. Adjust the current at the current moment according to the available current corresponding to the temperature level.

[0050] Specifically, after determining the temperature level that matches the current temperature through the above step S203, the available current at the current time is determined according to the temperature level, and the current at the current time is adjusted to be an available current.

[0051] In some implementations, the available current corresponding to the preset temperature level can be an accurate value. That is, when the current temperature belongs to this temperature level, regardless of whether the current temperature is a larger value or a smaller value in this temperature level, this accurate value is selected as the available current.

[0052] The charging method for the earphone charging case provided in this embodiment can adjust the current level in a timely manner when the temperature of the earphone charging case becomes high due to increased charging time. This slows down the rate of temperature increase, reduces damage to the components of the earphone charging case, protects the battery and other components inside the earphone charging case, and extends the service life of the earphone charging case.

[0053] In some embodiments, when the temperature drops below the charging temperature threshold, the available current can be adjusted to the initial current before charging the earphones. Specifically, this may include: after the earphone charging case charges according to the available current, obtaining the change in the adjusted temperature; determining whether the changed temperature is lower than the charging temperature threshold based on the change; if the changed temperature is lower than the charging temperature threshold, then adjusting the available current to the initial current to charge the earphones.

[0054] The initial current can be understood as the current flowing when the earbuds are placed in the charging case, the case detects that the earbuds need charging, and begins charging them. Since the charging case operates for a short period at the beginning of charging, its temperature is generally at its lowest point during the entire charging process. Therefore, the initial current at this point is generally considered to be the highest current during the entire charging process.

[0055] Specifically, once the earphone charging case starts charging based on the available current, the available current is often lower than the initial current at the beginning of charging. Therefore, after adjustment, the temperature of the earphone charging case may gradually recover, or the temperature may not rise significantly further. Throughout the charging process, based on the temperature changes, determine whether the changed temperature is lower than the charging temperature threshold. If the changed temperature is lower than the charging temperature threshold, it means that after adjusting the current according to the available current, the temperature of the earphone charging case is beginning to approach the normal temperature when not charging, or it can be said that the damage caused by temperature to the earphone charging case is negligible. At this point, the available current can be adjusted to the initial current to charge the earphones, thereby improving the charging speed.

[0056] With the method provided in this embodiment, when charging the earphones according to the available current, the rate of temperature increase inside the earphone charging case may slow down, and the temperature may even gradually drop below the charging temperature threshold after adjusting the current. At this time, the available current can be adjusted to the initial current to speed up the charging speed.

[0057] In some embodiments, when the temperature is below a charging temperature threshold, the applicable current corresponding to the current battery level of the headphones can be determined by the battery level corresponding to the headphone's current battery value, and this applicable current can be used as the optimal applicable current to charge the headphones. Specifically, this may include: if the temperature is below the charging temperature threshold, obtaining the headphone's battery value; matching the battery value with the battery value corresponding to a preset battery level to determine the current battery level of the headphones; the preset battery level includes several battery levels; matching each battery level with its corresponding applicable current; determining the optimal applicable current for the current moment based on the applicable current corresponding to the preset battery level, and using the optimal applicable current to charge the headphones.

[0058] The preset battery level can be understood as the battery level corresponding to the earphones. This preset battery level can be determined during the manufacturing process. Furthermore, during the determination process, each preset battery level corresponds to an applicable current. This applicable current can both prevent the earphone charging case from overheating during charging at the corresponding battery level and adjust the current appropriately to meet the needs of fast charging at the corresponding battery level.

[0059] Specifically, when the thermistor in the above scenario detects that the temperature of the earphone charging case is below the charging temperature threshold, the earphones can be charged according to the initial current involved in the above embodiment. However, in actual implementation, the earphones are at different battery levels. As the earphone battery level increases, the required electrical energy decreases, but the electrical energy generated by charging the earphones with the same current remains unchanged. Therefore, more of the electrical energy generated by the current is wasted, and more electrical energy may be converted into heat energy, thus raising the temperature of the earphone charging case and causing some damage to the earphone charging case. Therefore, when the temperature of the earphone charging case is below the charging temperature threshold, the earphone battery level can be obtained and matched with a preset battery level to determine the battery level corresponding to the current battery level. This determines the applicable current corresponding to this battery level, and the current at the current moment is adjusted according to the applicable current to avoid the same amount of current generating excess electrical energy that is converted into heat energy and causes the earphone charging case temperature to rise as the earphone battery level increases.

[0060] In some implementations, the applicable current may be a fixed value or a range. The specific adjustment rules can be set according to the needs of the brand itself.

[0061] The method provided in this embodiment addresses the issue that when the earphone charging case temperature is below the charging temperature threshold, the required electrical energy decreases as the earphone battery level increases. However, the electrical energy generated by charging the earphones using the same current remains constant. Therefore, more of the electrical energy generated by the current is wasted, potentially leading to more energy being converted into heat, thus raising the charging case temperature. Therefore, by matching the earphone's battery level to the appropriate current for charging, excess electrical energy can be prevented from being converted into heat as the earphone battery level increases, thus extending the charging case's lifespan.

[0062] In some embodiments, a water-cooling device can be installed in the earphone charging case. When the temperature exceeds a charging temperature threshold, the water-cooling device dissipates the heat generated by the temperature increase, and the temperature is then compared with the charging temperature threshold again to adjust the current. Specifically, this may include: if the temperature exceeds the charging temperature threshold, dissipating the heat generated by the temperature increase using a pre-set water-cooling device; comparing the dissipated temperature with the charging temperature threshold based on the dissipation results, and determining how to adjust the current based on the comparison results.

[0063] A water-cooled heat dissipation device can be understood as a type of heat dissipation device. This device contains a metal block made of copper or aluminum with internal water channels. Furthermore, a circulating fluid, which can be water or other substances, continuously flows within these channels. This water-cooled heat dissipation device is typically placed in locations where heat may be generated. When the temperature rises, the circulating fluid absorbs heat and then circulates, gradually lowering the temperature.

[0064] In some implementations, heat pipes can be placed at the heat-generating locations to achieve heat dissipation and cooling. The specific heat dissipation method can be tailored to the characteristics of the earphones and their charging case; this embodiment does not impose any limitations.

[0065] Specifically, when the received temperature exceeds the charging temperature threshold, the water-cooling device configured in this embodiment can dissipate the heat generated by the temperature rise, gradually lowering the temperature. After a certain period of dissipation, as the temperature gradually decreases or stops rising, it may be necessary to adjust the current based on the temperature change. If the temperature is still higher than the charging temperature threshold, the temperature can be re-matched with the preset temperature level to determine if the temperature level has changed after dissipation. If it has changed, the current needs to be adjusted according to the available current corresponding to the dissipated temperature level, using the adjusted current to charge the headphones. If the dissipated temperature is lower than the charging temperature threshold, the initial current can be used to charge the headphones. Furthermore, to avoid the problem of excess energy being converted into heat and causing a temperature increase when the headphone battery level rises due to continuous use of the initial current, different battery levels corresponding to different battery levels can be used, as described in the above embodiments, to determine the appropriate current for charging the headphones based on the battery level.

[0066] The method described in this embodiment allows for timely absorption and dissipation of heat using a water-cooling device when the temperature rises, thus lowering the temperature. Furthermore, it adjusts the current promptly after temperature changes to prevent secondary heating, thereby protecting the earphone charging case and extending its lifespan.

[0067] In some embodiments, when the heat generated by the temperature is dissipated for a period of time using a water-cooling device, and the earphones are continuously charged with available current during this period, the temperature remains higher than the charging temperature threshold. At this point, the battery health value of the earphone charging case is obtained, and it is determined whether the battery health value is lower than a preset battery health threshold. If it is lower, a maintenance reminder command can be sent to the connected terminal device to prompt the user to promptly maintain the earphone charging case. Specifically, this may include: when the heat generated by the temperature is dissipated using a water-cooling device during a preset period of time, and the earphones are charged with available current, if the temperature after heat dissipation is higher than the charging temperature threshold, the battery health value of the earphone charging case is obtained; based on the preset battery health threshold, it is determined whether the battery health value of the earphone charging case is lower than the preset battery health threshold; if the battery health value is lower than the preset battery health threshold, a maintenance reminder command is sent to the terminal device to prompt the user to promptly maintain the case.

[0068] The preset time period can be understood as the period during which the temperature of the earphone charging case can drop or stabilize at a certain temperature value after the water cooling device is used.

[0069] Battery health ratings indicate the condition of the battery in the earphone charging case. A high battery health rating suggests that the battery in the charging case is in good condition and can charge the earphones effectively; a low battery health rating suggests that the battery in the charging case is in poor condition and may not charge the earphones properly.

[0070] As the charging case charges the earbuds repeatedly, the battery inside will gradually degrade. Furthermore, some users may have poor usage habits when using the charging case, which can also accelerate battery degradation. Therefore, a display screen can be installed on the outside of the charging case to display the battery health value. This battery health value can be used to characterize the battery's health status. A preset battery health threshold can be used to indicate the battery health value at which the charging case's battery is nearing its limit and can no longer provide adequate power to the earbuds. For example, the preset battery health threshold can be set to 65% of the health value of a healthy battery. When the battery health value is above 65%, it means the battery can still provide adequate power to the earbuds; when the battery health value is below 65%, even if the charging case's battery is fully charged, it may still not be able to fully charge two empty earbuds. In this case, the charging case's battery is considered to be severely degraded and may require repair.

[0071] In some implementations, a new earphone charging case comes with a healthy, unused battery that can potentially fully charge two completely depleted earphones four times. However, as the number of charging cycles increases, battery degradation gradually increases, potentially reducing the number of times the battery can fully charge two completely depleted earphones. Therefore, if the battery can fully charge two completely depleted earphones three times or more, it indicates that the battery can provide adequate power to the earphones. If the battery cannot even fully charge two completely depleted earphones once, it suggests that the battery is severely degraded and may require repair.

[0072] It should be noted that the numbers mentioned in the above description are for illustrative purposes only and have no real meaning. The specific preset battery health threshold value can be set according to the characteristics of the earphones and the earphone charging case.

[0073] Specifically, when the water-cooling system is activated to dissipate heat generated by the temperature for a period of time, and the current has been adjusted to the usable current corresponding to the current temperature level, if the temperature is still found to be higher than the charging temperature threshold, the earphone charging case battery may be converting most of the electrical energy generated by the current into heat energy instead of charging the earphones. In other words, the earphone charging case battery may not be able to charge the earphones effectively. Therefore, the battery health value of the earphone charging case can be obtained and compared with a preset battery health threshold to determine if the battery health value is lower than the preset threshold. If the battery health value is indeed lower than the preset threshold, a maintenance reminder command can be sent to the connected terminal device so that the user is aware that the earphone charging case may not be able to provide power to the earphones properly and needs to be maintained in time.

[0074] In some implementations, the user might place both earbuds in the charging case to charge, at which point neither earbud might be connected to a terminal device. In this case, the connection history of the earbuds can be retrieved, selecting the terminal device connected before being placed in the case. It can then be determined whether Bluetooth is enabled on this previously connected terminal device. If it is enabled, a maintenance reminder command can be sent. Alternatively, the connection history can be used to select the terminal device with the most connections and send a maintenance reminder command there.

[0075] In this embodiment, if the temperature remains above the charging temperature threshold or continues to rise after the water-cooling device dissipates heat and the current is adjusted to a usable level for charging the earphones for a period of time, it may indicate that the earphones in the charging case are severely worn and unable to provide adequate power. Instead, they are converting a significant portion of the electrical energy generated by the current into heat, requiring timely maintenance. To determine this, the battery health value of the earphone charging case can be obtained and it can be determined whether the battery health value is below a preset battery health threshold. This allows for timely sending of a maintenance reminder to the terminal device when the battery is severely worn and requires maintenance, preventing a poor user experience caused by the earphone charging case being unable to charge the earphones without the user's knowledge.

[0076] In some embodiments, if the charging case has a low battery level, power supply to the earbuds can be stopped. Specifically, this may include: obtaining the battery level of the charging case; comparing the battery level with a first preset battery level threshold to determine whether the battery level is lower than the first preset battery level threshold; and if the battery level is lower than the first preset battery level threshold, stopping power supply to the earbuds.

[0077] The first preset battery threshold can be understood as the amount of power the earphone charging case's battery can provide to the earphones without damaging its own battery. For example, if charging the earphones when the battery level is below 15% of the total battery level may cause some damage to the battery, then the first preset battery threshold can be set to 15% of the total battery level.

[0078] Specifically, the battery level of the earphone charging case is obtained and compared with a preset battery level threshold. If the battery level is lower than the first preset threshold, power can be stopped to the earphones to reduce battery wear.

[0079] In a specific implementation, when the battery level of the earphone charging case is lower than a first preset power threshold, a low battery reminder can be sent to the terminal device so that the user is aware that the current battery level of the earphone charging case is low and cannot provide power to the earphones.

[0080] The method provided in this embodiment can stop supplying power to the earphones in a timely manner when the battery of the earphone charging case is low, avoiding the loss caused by the battery continuing to charge the earphones when the battery is low, thereby extending the battery life of the earphone charging case.

[0081] In some embodiments, if the charging case has a low battery and the earbuds also have a very low battery, the earbuds can be charged when an external power source is connected. Specifically, this may include: if the battery level is lower than a first preset battery level threshold, obtaining the earbuds' battery level and determining whether the earbuds' battery level is higher than a second preset battery level threshold; if the earbuds' battery level is lower than the second preset battery level threshold, then when the charging case is connected to an external power source, the current generated by the external power source will be used to charge the earbuds.

[0082] The second preset battery threshold can be understood as the battery level at which the earphones can be used normally for a period of time before completely running out of power. For example, it could be the battery level corresponding to half an hour of music playback, or the battery level at which the earphones can maintain their power until the charging case is fully charged. In this embodiment, the second preset battery threshold can be the battery level of the earphones corresponding to the time required to maintain their power until the charging case is fully charged.

[0083] Specifically, if the charging case's battery level falls below a first preset threshold, the charging case will stop charging the earbuds, and they will need to be connected to an external power source for charging. At this point, the earbuds' battery level can be checked to determine if they can remain powered on until the charging case's battery is fully charged. This means checking if the earbuds' battery level is above a second preset threshold. If the earbuds' battery level is below the second preset threshold, it means the earbuds' battery cannot support the user until the charging case's battery is fully charged, and the user may also need to charge the earbuds. Therefore, when the earbuds are placed back in the charging case and connected to an external power source, the earbuds will be charged first.

[0084] In some implementations, the earbuds are charged until the charging case's battery is fully charged. At this point, users can choose not to fully charge the earbuds and instead switch to charging the charging case directly. This ensures that the charging case's battery is charged promptly and that users can continue using the earbuds until the charging case is fully charged.

[0085] The method provided in this embodiment can determine whether the earphone's battery level is higher than a second preset battery threshold when the earphone charging case battery needs to be charged. If it is lower than the second preset battery threshold, the earphone will be charged first when it is placed in the earphone charging case and connected to an external power source. This ensures that users do not have to worry about the earphone's battery not being able to support the earphone until the earphone charging case battery is fully charged, thus improving the user experience.
