Description

Technical Field

[0001] This invention relates to the field of charging equipment technology for mobile terminals, and more specifically to a temperature-based power adapter protection method, system, and computer device. Background Technology

[0002] To meet the demands of people's fast-paced lifestyles, manufacturers of existing mobile devices (such as smartphones, tablets, and smartwatches) are constantly increasing charging power to shorten battery charging time. However, as the charging power of mobile devices continues to increase, the requirements for power adapters and their manufacturing costs also increase accordingly.

[0003] Furthermore, the number of users owning multiple mobile devices is increasing, and the charging power of different devices is not significantly different. Therefore, requiring dedicated power adapters for different types or manufacturers of mobile devices would not only increase costs but also waste resources. In response to environmental policies, manufacturers have gradually standardized the charging interfaces used in their mobile devices and even started offering power adapters as optional accessories.

[0004] In response to this situation, a power adapter has been introduced to the market that is compatible with the charging needs of different mobile devices. Some mobile devices, due to their use of fast charging technology, can charge at extremely high power. Although the device has a temperature detection submodule to monitor the battery temperature and reduce the charging power when the battery temperature is too high, preventing spontaneous combustion or affecting the battery's lifespan due to overheating during charging.

[0005] However, the inventors discovered that in addition to the battery overheating during charging, which affects its lifespan and can even cause spontaneous combustion, the power adapter also overheats due to prolonged charging with excessive power. This causes the internal electronic components to age due to prolonged exposure to high temperatures. Once the circuit ages and overheats, it is prone to overcurrent and circuit breakage, resulting in irreversible damage and ultimately destroying the power adapter.

[0006] Furthermore, the inventors discovered that while current mobile terminals and power adapters are compatible with different charging protocols, the mobile terminal typically selects the optimal charging method during the charging process. For example, it might use a fast charging protocol (high power) when the battery is low, and then switch to trickle charging mode (low power) once the battery reaches 80%. The power adapter, however, passively adjusts its output power in response to the mobile terminal's selection. This is problematic because if the power adapter continues to operate in the same way when poor heat dissipation leads to overheating or internal components malfunction, it becomes very passive, easily damaging internal components and potentially causing safety accidents.

[0007] In summary, there is a need to develop a temperature-based power adapter protection method and system to adjust the operating state of the power adapter based on temperature, protect the power adapter from malfunction, extend its service life, and improve safety. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the defects of existing power adapters that are prone to malfunctions or even safety accidents due to long-term operation at high temperatures. The invention provides a temperature-based power adapter protection method, system and computer equipment, so as to adjust the working state of the power adapter based on temperature, protect the power adapter to work normally, thereby extending its service life and improving safety.

[0009] To achieve the above objectives, the present invention provides a first aspect through the following technical solution: a temperature-based power adapter protection method, applicable to situations where a mobile terminal is charged via a power adapter, including,

[0046] Example:

[0047] like Figure 1 As shown, this invention provides a temperature-based power adapter protection method applicable to charging mobile terminals. It adjusts the power adapter's operating state based on temperature, with different temperatures corresponding to different operating modes. Under each operating mode, overcurrent protection actions are executed according to specific conditions. Furthermore, preset overcurrent protection values ​​are dynamically adjusted based on different operating modes to protect the power adapter's normal operation, thereby extending its lifespan and improving safety. The temperature-based power adapter protection method includes the following steps:

[0048] S2: Obtain the temperature of the power adapter.

[0049] The temperature of the power adapter is obtained by taking the average temperature of the power adapter within t1, t2 and t3 seconds, which are T1, T2 and T3 respectively; where 1s≤t1<t2<t3≤10s.

[0050] S4: Determine the current operating mode of the power adapter based on its temperature. The operating mode includes a low-temperature operating mode and a non-low-temperature operating mode; the non-low-temperature operating mode further includes a normal-temperature operating mode, a high-temperature operating mode, and an ultra-high-temperature operating mode.

[0051] S6: Obtain the current intensity of the power adapter.

[0052] The acquisition of the current intensity of the power adapter refers to the current data of the power adapter in t4 seconds, t5 seconds, and t6 seconds, which are I1, I2, and I3 respectively; where 30s≤t6<t5<t4≤300s.

[0053] S8: Determine the current protection level of the power adapter that requires overcurrent protection based on the current intensity of the power adapter and the operating mode; the higher the current intensity of the power adapter, the higher the current protection level that requires overcurrent protection; at the same current intensity, the higher the temperature of the power adapter, the higher the current protection level that requires overcurrent protection.

[0054] S10: In response to the power adapter's operating mode being a low-temperature operating mode, reduce the power adapter's output power by at least 1 / 3.

[0055] In response to the power adapter's operating mode being a non-low temperature mode, the output power of the power adapter is controlled according to the current protection level; the current protection level and the power adapter's output power are negatively correlated. The specific execution method is as follows:

[0056] In response to the operating mode being the normal temperature operating mode and the current protection level being the low protection level, the output power of the power adapter is controlled to be P1;

[0057] In response to the operating mode being the high-temperature operating mode and the current protection level being the low protection level, the output power of the power adapter is controlled to be P2;

[0058] In response to the operating mode being the normal temperature operating mode and the current protection level being the medium protection level, the output power of the power adapter is controlled to be P3;

[0059] In response to the operating mode being the high-temperature operating mode and the current protection level being the medium protection level, the output power of the power adapter is controlled to be P4;

[0060] In response to the operating mode being the normal temperature operating mode and the current protection level being the high protection level, the output power of the power adapter is controlled to be P5;

[0061] In response to the operating mode being the high-temperature operating mode and the current protection level being the high protection level, the output power of the power adapter is controlled to be P6;

[0062] Among them, the output power of the power adapter in normal temperature working mode is 90% > P1 > P2 > P3 > P4 > P5 > P6 > 40% of the output power of the power adapter in normal temperature working mode.

[0063] In response to the power adapter's operating mode being an ultra-high temperature operating mode, the power adapter's output is turned off.

[0064] Specifically, in step S4, the current operating mode of the power adapter is determined through the following steps:

[0065] S41: Obtain the temperature value T0 of the power adapter during normal operation.

[0066] S42: Calculate Wd(ti), Wd(ti)=((Ti-T0) / T0)*100%, i=1, 2, 3.

[0067] S43: If Wd(t1)≤X1, then the current operating mode of the power adapter is determined to be the low-temperature operating mode. If X1<Wd(t2)≤X2, then the current operating mode of the power adapter is determined to be the normal-temperature operating mode. If X2<Wd(t2)≤X3, then the current operating mode of the power adapter is determined to be the high-temperature operating mode, where 0<X1<X2<X3≤1.

[0068] Specifically, in step S8, the current protection level for overcurrent protection of the power adapter is determined through the following steps:

[0069] S61: Obtain the current I0 of the power adapter during normal operation.

[0070] S62: In the current data I1 within t4 seconds, find the portion where the current is greater than I0 and the time exceeds (t4) / 6 seconds, and calculate the average current I11 of this portion; In the current data I2 within t5 seconds, find the portion where the current is greater than I0 and the time exceeds (t5) / 6 seconds, and calculate the average current I21 of this portion; In the current data I2 within t6 seconds, find the portion where the current is greater than I0 and the time exceeds (t6) / 6 seconds, and calculate the average current I31 of this portion.

[0071] S63: Calculate Cg(Ii), Cg(Ii) = ((Ii1-I0) / I0) * 100%, i = 1, 2, 3.

[0072] S64: If Y1≤Cg(I1)<Y2, then the power adapter requires low-level overcurrent protection. If Y2≤Cg(I2)<Y3, then the power adapter requires medium-level overcurrent protection. If Y3≤Cg(I3), then the power adapter requires high-level overcurrent protection, where 5%≤Y1<Y2<Y3≤40%.

[0073] This embodiment also provides a temperature-based power adapter protection system, including a communication module, a charging module, an overcurrent protection module, a sensor detection module, a data storage module, and a computing module, etc. Figure 2 As shown, the temperature-based power adapter protection system uses the temperature-based power adapter protection method during operation.

[0074] The sensor detection module includes a temperature detection submodule (detected by a temperature sensor) and a current detection submodule (detected by a current sensor). The temperature detection submodule detects the temperature of the power adapter in real-time when the power adapter and mobile terminal are properly connected. The operating mode of the power adapter is determined based on the temperature readings over a period of time. The overcurrent protection module responds to the current detection submodule by determining the corresponding current protection level based on the current operating mode.

[0075] It should be noted that the data storage module consists of multiple data storage units, which can be located on a single memory or on multiple distributed memory locations, and are used to store the detection values ​​and intermediate processing data of the sensor detection module. For ease of description, the data storage units are numbered below for distinction.

[0076] The following provides a detailed description of the temperature detection submodule, the current detection submodule, and the current protection level adopted.

[0077] Determining Low-Temperature Operating Mode

[0078] The power adapter protection system detects the presence of a power adapter input and activates the temperature detection submodule to detect the current temperature in 1 second, saving it to data storage unit 01. The system then retrieves the power adapter model and saves it to data storage unit 02. Next, the system retrieves charging temperature data (the normal operating temperature value for the current power adapter model) from data storage unit 02 (via a communication module connected to a cloud server) and saves it to data storage unit 03 (40℃). Finally, the system multiplies this value by 50% and saves it to data storage unit 04 (20℃, representing the maximum temperature fluctuation). Finally, the system subtracts this value from data storage unit 04 and saves the result to data storage unit 05.

[0079] The power adapter protection system obtains data from data storage unit 03, divides it by data storage unit 05, multiplies it by 100%, and saves it to data storage unit 06. If the data obtained from data storage unit 06 is less than or equal to 25%, the power adapter protection system determines that the power adapter is in low-temperature operating mode, sets the weight to 1, and saves the data and weight to data storage unit 07.

[0080] The power adapter protection system shuts down half of the threads, saves the control commands, turns off 50% of the USB interface output, and starts the temperature detection mode 3 minutes later.

[0081] Determining the normal temperature working mode

[0082] The power adapter protection system detects the presence of a power adapter input. It then activates the temperature detection submodule to measure the current 3-second temperature, obtains the average value, and saves it to data storage unit 08. Next, it retrieves the power adapter model and saves it to data storage unit 09. Data storage unit 09 then retrieves the cloud-based charging temperature data (obtaining the normal operating temperature value for the current power adapter model) and saves it to data storage unit 10 (40℃). Finally, it multiplies this value by 50% and saves it to data storage unit 11 (20℃, representing the maximum temperature fluctuation). Finally, it subtracts data storage unit 11 from data storage unit 08 and saves the result to data storage unit 12.

[0083] The power adapter protection system obtains data from data storage unit 10, divides it by data storage unit 12 multiplied by 100%, and saves the result to data storage unit 13. If the percentage obtained from data storage unit 13 is greater than 25% but less than 75%, the power adapter protection system determines it to be in temperature mode in the power adapter, sets the weight to 10, and saves the data and weight to data storage unit 14. The power adapter protection system activates the temperature detection mode after 2 minutes.

[0084] Determining High-Temperature Operating Modes

[0085] The power adapter protection system detects the presence of a power adapter input. It then activates the temperature detection submodule to measure the temperature over 4 seconds, averages the readings, and saves the average to data storage unit 15. Next, the system retrieves the power adapter model and saves it to data storage unit 16. Data storage unit 16 then retrieves the cloud-based charging temperature data (the normal operating temperature value for the current power adapter model) and saves it to data storage unit 17 (40℃). Finally, the system multiplies this value by 50% and saves it to data storage unit 18 (20℃, representing the maximum temperature fluctuation). Finally, the system subtracts data from data storage unit 18 from data storage unit 15 and saves the result to data storage unit 19.

[0086] The power adapter protection system obtains data from data storage unit 17, divides it by data storage unit 19, multiplies it by 100%, and saves the result to data storage unit 20. If the percentage obtained from data storage unit 20 is greater than or equal to 75% but less than 100%, the power adapter protection system determines it to be in high-temperature mode, sets the weight to 50, and saves the data and weight to data storage unit 21. The power adapter protection system then activates the charger temperature detection mode after 1 minute.

[0087] Determining the operating mode at extremely high temperatures

[0088] The power adapter protection system detects the presence of a power adapter input. It then activates the temperature detection submodule to measure the temperature over 5 seconds, averages the readings, and saves the average to data storage unit 22. Next, the system retrieves the power adapter model and saves it to data storage unit 23. Data storage unit 23 then retrieves the cloud-based charging temperature data (the normal operating temperature value for the current power adapter model) and saves it to data storage unit 24 (40℃). Finally, the system multiplies the data storage unit reading by 50% and saves it to data storage unit 25 (20℃, representing the maximum temperature fluctuation). Finally, the system subtracts data storage unit 25 from data storage unit 22 and saves the result to data storage unit 26.

[0089] The power adapter protection system obtains data from data storage unit 24 divided by data storage unit 26 multiplied by 100%, and saves it to data storage unit 27. If data storage unit 27 obtains a value greater than or equal to 100%, the power adapter protection system determines that the power adapter is in high-temperature mode, sets the weight to 100, and saves the data and weight to data storage unit 28. The power adapter protection system shuts down the power adapter's charging USB output, uploads data to the cloud, and the cloud returns a message to remind the user (charging has stopped due to overheating). After 30 seconds, the power adapter protection system activates the charger temperature detection mode. If the temperature is not high, the power adapter protection system enables the power adapter's USB input.

[0090] The power adapter protection system obtains cloud data to detect the number of times the power adapter has been exposed to high temperatures in a week and saves it to data storage unit 29. When the number of high temperatures detected by the power adapter protection system in data storage unit 29 is greater than 10, the power adapter protection system activates the power adapter alarm for 5 seconds and sends a message to remind the user (the charger has been exposed to high temperatures for too long, please replace or check the charger in time).

[0091] The power adapter protection system acquires data and weights from data storage units 28, 21, 14, and 7, and saves them to data storage unit 30.

[0092] The specific algorithm is as follows:

[0093] Pj_Wd(x1) = 45℃ / / Current average temperature of the power adapter (45℃)

[0094] Wd_bdz(x2) = 20℃ / / Maximum temperature fluctuation (20℃)

[0095] Zc_gzwd(x3) = 40℃ / / Normal operating temperature of the power adapter (40℃)

[0096] Wd_bj(y1) = 62.5% / / Current temperature percentage (62.5%)

[0097] Wd_bj(y1)=[Pj_Wd(x1)-Wd_bdz(x2)] / Zc_gzwd(x3)*100%

[0098] Current detection submodule (When the system obtains that the temperature is not too high and will not damage the equipment, the system will use a current sensor to judge a current to determine whether it is an overcurrent protection condition)

[0099] When the power adapter protection system obtains a preset value of 30 less than or equal to 50 from the data storage unit, the power adapter protection system starts a thread. The thread obtains device conditions in three judgment modes:

[0100] The first type: low-intensity current from the power adapter.

[0101] The power adapter protection system activates the current sensor to prevent overcurrent from causing a circuit break that could lead to irreversible damage to the power adapter.

[0102] The power adapter protection system connects to the cloud to obtain the current value supported by the current power adapter for normal operation and saves it to data storage unit 43. The system also obtains the current value of the current power adapter over 3 minutes via a current sensor and saves it to data storage unit 44. The system compares the values ​​in data storage units 43 and 44. If the value in data storage unit 44 exceeds the value in data storage unit 43 by 30 seconds, the system saves the excess time and value to data storage unit 45. The system then averages the value in data storage unit 45 with the time value in data storage unit 45 to obtain the average current value, which is saved to data storage unit 46. The system compares the current value in data storage unit 46 with the current value in data storage unit 43. If the value in data storage unit 46 is greater than or equal to the value in data storage unit 43 by 5% but less than 20%, it is determined to be a low-intensity overcurrent mode. The system then obtains the current intensity and determines that an overcurrent may occur, potentially damaging the smart device. A weight of 1 is set, and the data and weight are saved to data storage unit 47. The smart system obtains the data from data storage unit 47 and sends it to the cloud via a wireless network module. The cloud then sends the data back to the smartphone and notifies the user of the current status of the power adapter and the obtained current value.

[0103] The second type: high current in the power adapter

[0104] The power adapter protection system activates the current sensor to prevent overcurrent from causing a circuit break that could lead to irreversible damage to the power adapter.

[0105] The power adapter protection system connects to the cloud to obtain the current value supported by the current power adapter for normal operation and saves it to data storage unit 53. The system also obtains the current value of the current power adapter over 2 minutes via a current sensor and saves it to data storage unit 54. The system compares the values ​​in data storage units 53 and 54. If the value in data storage unit 54 exceeds the value in data storage unit 53 by 20 seconds, the system obtains the excess time and value and saves it to data storage unit 55a. The system then averages the value in data storage unit 55 with the time in data storage unit 55 to obtain the corresponding average current value and saves it to data storage unit 56. The system compares the current value in data storage unit 56 with the current value in data storage unit 53. If the value in data storage unit 56 is greater than or equal to the value in data storage unit 53 by 20% but less than 40%, it is determined to be a medium-intensity overcurrent mode. The system obtains the current intensity and determines that an overcurrent may occur, potentially damaging the smart device. A weight of 10 is set, and the data and weight are saved to data storage unit 58. The intelligent system acquires data from the data storage unit 58 and sends it to the cloud via the wireless network module. The cloud then sends the data back to the smartphone and notifies the user of the current status of the power adapter and the acquired current value.

[0106] The third type: high-intensity current from the power adapter.

[0107] The power adapter protection system activates the current sensor to prevent overcurrent from causing a circuit break that could lead to irreversible damage to the power adapter.

[0108] The power adapter protection system connects to the cloud to obtain the current value supported by the current power adapter for normal operation and saves it to data storage unit 63. The system also obtains the current value of the current power adapter over 1 minute using a current sensor and saves it to data storage unit 64. The system compares the values ​​in data storage units 63 and 64. If the value in data storage unit 64 exceeds the value in data storage unit 63 by 10 seconds, the system obtains the excess time and saves the excess value to data storage unit 65. The system then averages the value in data storage unit 65 with the time value in data storage unit 65 to obtain the average current value and saves it to data storage unit 66. The system compares the current value in data storage unit 66 with the current value in data storage unit 63. If the value in data storage unit 66 is greater than or equal to the value in data storage unit 63 by 40%, it is determined to be a high-intensity overcurrent mode. The system obtains the current intensity and determines that an overcurrent may occur, potentially damaging the smart device. A weight of 100 is set, and the data and weight are saved to data storage unit 68. The smart system obtains the data from data storage unit 68 and sends it to the cloud via a wireless network module. The cloud then sends the data back to the smartphone and notifies the user of the current status of the power adapter and the obtained current value.

[0109] The power adapter acquires the data and weights from data storage units 48, 58, and 68, and saves them to data storage unit 70.

[0110] The specific algorithm is as follows:

[0111] Sj_Zcdl(x1)=0.5A / / Normal operating current (0.5A)

[0112] Dq_cgdlz(x2)=63A / / Current current exceeds the total value (63A)

[0113] Dq_cgsj(x3)=90s / / Current current exceeds time (90s)

[0114] Cg_bl(y1)=40% / / Current current exceeds the proportion (40%)

[0115] Cg_bl(y1)=[Dq_cgdlz(x2) / Dq_cgsj(x3) / Sj_Zcdl(x1)-1]*100%

[0116] 3. Power adapter overcurrent protection module (the system acquires the current status, decomposes the current status, and makes corresponding adjustments to protect the equipment).

[0117] When the weight of data storage unit 70 obtained by the power adapter is greater than or equal to 1, the overcurrent protection thread is activated, and the power adapter starts the overcurrent protection module, which is judged in three cases:

[0118] Type 1: Low-level current protection of the power adapter

[0119] The power adapter protection system starts by acquiring the weight of the data storage unit 70. When the weight is equal to 1, the power adapter protection system starts the low-level current protection of the power adapter.

[0120] The power adapter protection system acquires current data from data storage unit 70 and saves it to data storage unit 69a. The power adapter protection system reads the weight value from data storage unit 39.

[0121] When the weight of data storage unit 39 is less than 50, the power adapter protection system connects to the cloud to obtain the current power adapter charging efficiency and saves it to data storage unit 71a. The power adapter protection system adjusts the USB output to 80%. After adjustment, the power adapter protection system obtains the current power adapter charging efficiency and saves it to data storage unit 72a. The power adapter protection system compares data storage unit 71a and data storage unit 72a. If the value of data storage unit 71a is less than 10% of the value of data storage unit 72a, the execution is considered successful. The power adapter protection system saves the control command as 1 and saves the adjustment time and control command to data storage unit 73a.

[0122] When the weight of data storage unit 39 equals 50, the power adapter protection system adjusts the USB output to 70%. After adjustment, the power adapter protection system activates the temperature detection module to acquire and save the value to data storage unit 40. The power adapter protection system determines that the weight of data storage unit 40 is less than 50, thus confirming successful execution. The power adapter protection system saves the control command as 1 and saves the adjustment time and control command to data storage unit 74.

[0123] The second type: Level current protection in the power adapter.

[0124] The power adapter protection system starts by acquiring the weight of the data storage unit 70. When the weight is equal to 10, the power adapter protection system starts the level current protection of the power adapter.

[0125] The power adapter protection system acquires current data from data storage unit 70 and saves it to data storage unit 46. The power adapter protection system reads the weight from data storage unit 39.

[0126] When the weight of data storage unit 39 is less than 50, the power adapter protection system connects to the cloud to obtain the current power adapter charging efficiency and saves it to data storage unit 71b. The power adapter protection system adjusts the USB output to 65%. After adjustment, the power adapter protection system obtains the current power adapter charging efficiency and saves it to data storage unit 72b. The power adapter protection system compares data storage unit 71b with data storage unit 72b. If the value of data storage unit 71b is less than 10% of the value of data storage unit 72b, the execution is considered successful. The power adapter protection system saves the control command as 1 and saves the adjustment time and control command to data storage unit 73b.

[0127] When the weight of data storage unit 39 equals 50, the power adapter protection system adjusts the USB output to 55%. After adjustment, the power adapter protection system activates the temperature detection module to acquire the value and save it to data storage unit 71c. The power adapter protection system then determines that the weight of data storage unit 51 is less than 50, indicating successful execution. The power adapter protection system saves the control command as 1 and saves the adjustment time and control command to data storage unit 73c.

[0128] The third type: High-level current protection for the power adapter

[0129] The power adapter protection system starts by acquiring the weight of data storage unit 70. When the weight equals 100, the power adapter protection system activates the high-level current protection of the power adapter.

[0130] The power adapter protection system acquires current data from data storage unit 70 and saves it to data storage unit 53. The power adapter protection system activates the temperature detection module to acquire values ​​and saves them to data storage unit 54. The power adapter protection system then acquires the weights from data storage unit 54.

[0131] When the weight of data storage unit 54 is less than the preset value of 50, the power adapter protection system connects to the cloud to obtain the current power adapter charging efficiency and saves it to data storage unit 55. The power adapter protection system adjusts the USB output to 50%. After adjustment, the power adapter protection system obtains the current power adapter charging efficiency and saves it to data storage unit 56. The power adapter protection system then uses data storage unit 55 to evaluate data storage unit 56. If the value of data storage unit 55 and the value of data storage unit 56 are less than 10%, the operation is considered successful. The power adapter protection system saves the control command as 1 and saves the adjustment time and control command to data storage unit 57.

[0132] When the weight of data storage unit 54 equals the preset value of 50, the power adapter protection system adjusts the USB output to 45%. After adjustment, the power adapter protection system activates the temperature detection module to acquire the value and saves it to data storage unit 58. If the weight of data storage unit 58 is less than the preset value of 50, the power adapter protection system determines that the execution was successful. The power adapter protection system saves the control command as 1 and saves the adjustment time and control command to data storage unit 59.

[0133] The power adapter protection system acquires data from data storage units 59, 57, 52, 50, 45, and 43, and saves the data to data storage unit 60.

[0134] Power adapter protection effect demonstration module

[0135] The power adapter protection system acquires data from the data storage unit 60. When the control command is 1, the power adapter protection system acquires the protection adjustment time and displays the effect to the cloud.
