Description

Technical Field

[0001] The present invention relates to the technical field of power supply equipment management, and in particular to a charging and discharging method, device and equipment for adjusting power of a power supply. Background Art

[0002] In today's era of rapid technological advancement, various electronic devices such as smartphones, tablets, and electric vehicles have become an integral part of people's lives and work. The normal operation of these devices depends on a stable and efficient power supply, making power charging and discharging technology particularly important.

[0003] Currently, some technologies attempt to use temperature data to adjust charging power during the charging and discharging process. A common approach involves simply monitoring the ambient temperature to adjust charging power. This approach assumes that ambient temperature affects the device's charging performance. When the ambient temperature is too high or too low, the charging power is appropriately adjusted to ensure charging safety and battery life. However, this approach has significant drawbacks. The ambient temperature does not accurately reflect the actual heat generated by the device during charging. For example, in hot outdoor environments, even if the device itself does not generate much heat due to charging, the high ambient temperature may cause the charging power to be excessively reduced, resulting in prolonged charging times and a negative user experience. Furthermore, the heat generation of different devices at the same ambient temperature can vary significantly, making charging power adjustment based solely on ambient temperature ineffective.

[0004] Another existing technology uses only the device's own temperature to adjust charging power. This approach more directly reflects the device's heating status during charging and discharging. When the device's temperature is too high, the charging power is reduced to prevent overheating and damage, maintaining a reliable temperature range in both winter and summer.

[0005] However, this approach also has its shortcomings. Handheld devices operate in different external environments, especially when the power bank is moved in spaces with varying temperatures. Regarding the impact of temperature on charging and discharging efficiency, adjusting charging power based solely on ambient temperature or the power bank's own temperature data is not accurate enough.

[0006] If the outside temperature is too high, the power bank's heat dissipation will deteriorate. Continuous high-power charging and discharging will cause the temperature to rise rapidly, requiring the controller to lower the threshold and reduce the charging and discharging power in advance to prevent heat accumulation and cause overheating protection. Therefore, the charging and discharging control of existing power banks cannot dynamically meet the above requirements. How to accurately adjust the charging power of the power bank based on its own temperature and the ambient temperature during operation requires considering both the external environment and the housing temperature to achieve more precise adjustment of the charging and discharging power of the power bank.

[0007] Therefore, whether adjusting the charging power by obtaining the ambient temperature or the temperature of the device itself, the charging and discharging device cannot adjust the charging power more accurately.

[0008] In this regard, the above technical problems need to be solved. Summary of the Invention

[0009] In order to overcome the shortcomings of the existing technology, the present invention proposes a charging and discharging method, device and equipment for adjusting the power of a power supply, the purpose of which is to reasonably adjust the charging power according to the external ambient temperature of the device and the temperature of the device itself, avoiding the blindness and lack of specificity of adjusting the charging power based solely on the ambient temperature or the device's own temperature, and providing a more scientific and reasonable solution for the charging and discharging of the power supply.

[0010] In order to achieve the above object, the present invention provides a charging and discharging method for adjusting power of a power supply, comprising the following steps:

[0011] Acquiring external temperature data and internal temperature data of the first device;

[0012] determining a temperature range of the first device according to the external temperature data and outputting a preset temperature threshold corresponding to the temperature range;

[0013] Determining whether the self-temperature data exceeds the preset temperature threshold;

[0014] If it exceeds, outputting a first charging control signal to the charging power adjustment module to enable the charging power adjustment module to execute the first charging mode;

[0015] If it does not exceed, a second charging control signal is output to the charging power adjustment module according to the preset temperature threshold, so that the charging power adjustment module executes the second charging mode.

[0016] Furthermore, the step of determining the temperature range of the first device according to the external temperature data and outputting a preset temperature threshold corresponding to the temperature range is characterized in that:

[0017] There is a pre-stored temperature threshold list;

[0018] The temperature threshold list includes at least one temperature interval and a preset temperature threshold corresponding to the temperature interval;

[0019] According to a matching result between the external temperature data and the temperature threshold list, a temperature range of the first device and a corresponding preset temperature threshold are determined.

[0020] Furthermore, the temperature range includes a high temperature range, a medium temperature range and a low temperature range;

[0021] Before outputting the first charging control signal to the charging power adjustment module, the method further includes the following third determination step:

[0022] Determining whether the external temperature data is within the low temperature range;

[0023] If the external temperature data is within the low temperature range, then continue to determine whether the internal temperature data exceeds a preset temperature threshold corresponding to the low temperature range;

[0024] If not, outputting a first charging control signal to the charging power adjustment module to enable the charging power adjustment module to execute a first charging mode;

[0025] If it exceeds, outputting a second charging control signal to the charging power adjustment module according to the preset temperature threshold, so that the charging power adjustment module executes the second charging mode and, during the execution of the second charging mode, continuously receives the own temperature data and determines whether it exceeds the second preset temperature threshold;

[0026] If the temperature does not exceed the second preset threshold, executing the second charging mode;

[0027] If the temperature exceeds the second preset threshold, the charging mode is switched to the first charging mode.

[0028] Furthermore, the method of determining the preset temperature threshold of the first device according to the external temperature data includes the following first judgment step:

[0029] Determine whether the external temperature data is in the temperature threshold list;

[0030] If the external temperature data belongs to the temperature threshold list, the temperature interval corresponding to the external temperature data is analyzed and processed, and the preset temperature threshold corresponding to the temperature interval is determined;

[0031] If the external temperature data is not in the temperature threshold list, an alarm signal is output to the charging indication status module.

[0032] Furthermore, the temperature threshold list includes a plurality of continuous and non-overlapping temperature intervals and preset temperature thresholds corresponding to each temperature interval;

[0033] The absolute difference between adjacent temperature intervals is a fixed value or a non-fixed value, and the preset temperature threshold corresponding to each temperature interval shows a gradual change rule as the temperature interval changes, and the gradual change rule includes linear gradual change or nonlinear gradual change.

[0034] Furthermore, the step of determining whether the temperature data exceeds the preset temperature threshold further includes:

[0035] Compare and judge its own temperature data with the preset temperature threshold at every preset time interval;

[0036] The preset time interval is any value between 10S and 60S.

[0037] Furthermore, the first device has a charging indication status module, and the charging indication status module has multiple display states;

[0038] Each of the display states corresponds to the first charging mode or the second charging mode.

[0039] Furthermore, the external temperature data is obtained through a communication module provided in the first device and an external meteorological agency, Internet of Things temperature collection device, geographic information system or APP terminal, or is obtained by a first temperature sensor provided on the first device.

[0040] A charge-discharge device for adjusting power of a power supply is proposed. When the charge-discharge device is in operation, it operates according to the charge-discharge method for adjusting power of a power supply described above. The charge-discharge device includes:

[0041] Control module, used to coordinate the normal operation of each module;

[0042] a first temperature module, the first temperature module being configured to detect the temperature of the housing and transmit a housing temperature signal to the control module;

[0043] a second temperature module, the second temperature module being used to detect the ambient temperature and transmit the ambient temperature signal to the control module;

[0044] The output end of the control module is electrically connected to the power adjustment module, and processes and analyzes the received housing temperature signal and the ambient temperature signal and transmits them to the power adjustment module.

[0045] In addition, a charging and discharging device with power adjustment is also proposed, comprising:

[0046] a housing having a control panel therein;

[0047] The control board is configured with a memory, a processor, and a processing program for adjusting the charging power stored in the memory and executable on the processor, wherein:

[0048] When the processing program for adjusting the charging power is executed by the processor, the steps of the charging and discharging method for adjusting the power of a power supply as described above are implemented.

[0049] The beneficial effects of the present invention are:

[0050] The present invention proposes a power supply charging and discharging method, apparatus, and device for adjusting power. The power supply charging and discharging method includes the steps of obtaining external temperature data and internal temperature data of a first device; determining a preset temperature threshold of the first device based on the external temperature data; and determining whether the internal temperature data exceeds the preset temperature threshold. If so, outputting a first charging control signal to the charging power adjustment module to cause the charging power adjustment module to execute a first charging mode; and if not, outputting a second charging control signal corresponding to the preset temperature threshold to the charging power adjustment module to cause the charging power adjustment module to execute a second charging mode. This allows for reasonable adjustment of the charging power based on the external ambient temperature and the internal temperature of the device, avoiding the blind and lack of specificity associated with adjusting the charging power based solely on ambient temperature or internal temperature.

DETAILED DESCRIPTION

[0057] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0058] As described in the background, in the prior art, during the charging and discharging process, charging power is typically adjusted by obtaining ambient temperature or the power supply's own temperature. Whether adjusting charging power based on ambient temperature or its own temperature, this approach is blind and lacks specificity, preventing the charging and discharging device from more accurately adjusting charging power.

[0059] The following will be combined with the Figure 1 To the attached Figure 4 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0060] Specifically, the present invention provides a power-adjustable charging and discharging method. The core of the method involves obtaining external temperature data and internal temperature data of the power supply, then determining a preset temperature threshold for the power supply based on the external temperature data. This preset temperature threshold is then compared with the internal temperature data to output a corresponding charging control signal to a charging power adjustment module, thereby causing the charging power adjustment module to execute a corresponding charging mode. Therefore, this power-adjustable charging and discharging method can adjust the output charging and discharging power according to the preset temperature threshold, ensuring the accuracy of the charging and discharging effect.

[0061] As shown in Figure 1, this figure illustrates the hardware device used to adjust power using the technology of this patented invention, namely, a charging and discharging device for adjusting power of a power supply. In this embodiment, this charging and discharging device can be used in a mobile power supply, a charging hub, or other charging devices to achieve precise adjustment of charging power.

[0062] In detail, the charging and discharging device 10 includes a control module 101 for coordinating the normal operation of each module; a first temperature module 102 is a temperature sensor, which is arranged on the inner wall of the shell or on the PCB or on the battery according to the actual usage scenario to obtain the temperature of these components that are prone to generate heat during operation.

[0063] In this embodiment, the first temperature module 102 is arranged on the inner wall of the shell to detect the temperature of the shell and transmit the shell temperature signal to the control module; the second temperature module 103 is also a temperature sensor, and the second temperature module 103 is used to detect the ambient temperature and transmit the ambient temperature signal to the control module 101; the output end of the control module 101 is electrically connected to the power adjustment module 104, and the shell temperature signal and the ambient temperature signal received are processed and analyzed and transmitted to the power adjustment module 104.

[0064] In this embodiment, the first temperature module 102 , the second temperature module 103 , and the power adjustment module 104 are all controlled by the control module 101 .

[0065] The control module 101 is based on comprehensive monitoring and analysis of the external ambient temperature and the power supply's own temperature to achieve precise adjustment of the charging power. Specifically, the first temperature module 102 is responsible for detecting the temperature of the outer shell. This temperature data can reflect the heating condition of the power supply itself; the second temperature module 103 is used to obtain the ambient temperature of the power supply. After the control module 101 receives the signals from the two temperature modules, it determines the corresponding preset temperature threshold based on the external temperature data according to the pre-set rules. Then, the preset temperature threshold is compared with the own temperature data, and a corresponding charging control signal is generated according to the comparison result. The power adjustment module receives the control signal and executes the corresponding charging mode, thereby achieving the purpose of flexibly adjusting the charging power according to different temperature conditions.

[0066] like Figures 2 to 3 The figure shows the device used to adjust power using the technology of the present invention, that is, a charging and discharging device for adjusting power of a power supply is proposed. The charging and discharging device is used to achieve precise adjustment of charging power. In this embodiment, the charging and discharging device includes any one of a mobile power supply, a charging hub, or other charging device, and the charging and discharging device is used to achieve precise adjustment of charging power.

[0067] In detail, the charging and discharging device 20 includes a housing 201, which contains a control board 202. The control board 202 is configured with a memory 203, a processor 204, and a processing program for adjusting the charging power stored in the memory 203 and executable on the processor 204, as well as a first temperature sensor 205, a second temperature sensor 206, a charging power adjustment module 207, a charging indication status module 208, a communication module 209, and a battery 210 controlled by the processor 204. Among them, the first temperature sensor 205 is used to obtain the ambient temperature data outside the charging and discharging device, the second temperature sensor 206 is used to obtain the temperature data of the charging and discharging device itself, the charging power adjustment module 207 includes a TYPE-C interface or USB and a power adjustment circuit and a boost circuit, so as to perform a handshake protocol with an external device to obtain a matching charging power, the charging indication status module 208 is used to indicate the current working status of the charging and discharging device, and the communication module 209 is used to communicate with an external device, such as connecting to an external thermometer or communicating with a mobile phone to obtain weather information from a weather APP on the mobile phone.

[0068] Specifically, the processor 204, as the computing core of the device, is responsible for reading the program in the memory 203, and performing calculations and judgments according to the rules in the program based on the temperature data obtained from the outside, thereby outputting corresponding control signals to adjust the charging power and achieve precise control of the charging and discharging process of the charging and discharging device.

[0069] The charging power adjustment processing program is executed by the processor 204 to implement the steps of a power supply charging and discharging method for adjusting power as described below. To better illustrate the method, the following is a detailed description of the method using a mobile power supply as an example.

[0070] Example 1

[0071] like Figure 4 It is shown that the charging and discharging method for adjusting the power of this power supply includes the following steps: S301: Obtaining external temperature data and self-temperature data of the first device. It should be noted that the first device includes a mobile power supply, a charger, or a charging manager for a drone, etc. In order to better reflect the charging and discharging method of the technical solution of the present invention, this embodiment uses a mobile power supply to specifically illustrate this charging and discharging method. The external temperature data should be understood as the ambient temperature data outside the mobile power supply shell that is not generated by the mobile power supply's own heat, and the self-temperature data should be understood as the temperature data generated inside the mobile power supply shell due to the mobile power supply's own heat during operation.

[0072] In actual use, the external temperature data is acquired through a communication module within the first device, such as by communicating with an external meteorological agency, an IoT temperature collection device, a geographic information system, or an app, or by a first temperature sensor on the first device. Of course, there are many other ways for the mobile power supply to acquire external temperature data, which are not listed here.

[0073] The following will illustrate this method using a scenario in which a temperature sensor disposed on the surface of a mobile power supply housing transmits external temperature data to the mobile power supply.

[0074] It should also be noted that the self-temperature data is transmitted by a temperature sensor located inside the mobile power supply housing. The temperature sensor can be located on the inner wall of the mobile power supply housing or anywhere near the control board or the mobile power supply battery to facilitate the acquisition of the temperature of the mobile power supply's heat-prone parts.

[0075] After step S301: acquiring external temperature data and internal temperature data of the first device, step S302 is executed: determining a temperature range of the first device according to the external temperature data and outputting a preset temperature threshold corresponding to the temperature range.

[0076] It should be noted that a temperature threshold list is pre-stored in the memory 203 in the first device; the temperature threshold list includes at least one temperature interval and a preset temperature threshold corresponding to the temperature interval; based on the matching result between the external temperature data and the temperature threshold list, the temperature interval and the corresponding preset temperature threshold of the first device are determined.

[0077] It should also be noted that the temperature threshold is set based on the fact that the charging and discharging device will heat up at different rates under different ambient temperatures. For example, in low-temperature environments, it will heat up more slowly, while in high-temperature environments, it will heat up more quickly. The preset temperature threshold is set to prevent the mobile power supply from being affected by different ambient temperatures when in different usage environments, which may affect its own temperature and prevent it from accurately matching the charging efficiency.

[0078] The temperature threshold list can be determined based on battery characteristics and safety range, experimental data and performance optimization, user needs and application scenarios, etc. These determination methods belong to the existing technology and will not be elaborated here one by one.

[0079] It should also be noted that the temperature interval includes a high temperature interval, a medium temperature interval and a low temperature interval; for example, the high temperature interval is 36°C-45°C, the medium temperature interval is 10°C-35°C, and the low temperature interval is -10°C-9°C; the preset temperature threshold corresponding to each temperature interval is, for example, the preset temperature threshold corresponding to the high temperature interval (36°C-45°C) is 35°C, the preset temperature threshold corresponding to the medium temperature interval (10°C-35°C) is 40°C, and the preset temperature threshold in the low temperature interval (-10°C-9°C) is 16°C. Of course, in actual use, the setting range of the temperature interval and the determination of the preset temperature threshold can be determined according to the actual use situation and can be further subdivided. The description here is only for the purpose of better illustrating the present technical solution and is not limited to the above cases.

[0080] During actual use of this example, when the external temperature data received by the processor 204 through the first temperature sensor 205 is 37°C, it is determined that the current temperature range of the first device is in the high temperature range, and the preset temperature threshold of 35°C corresponding to the high temperature range is output.

[0081] After executing step S302, execute step S303: determine whether the self-temperature data exceeds the preset temperature threshold; if so, output a first charging control signal to the charging power adjustment module to enable the charging power adjustment module to execute the first charging mode; if not, output a second charging control signal to the charging power adjustment module according to the preset temperature threshold to enable the charging power adjustment module to execute the second charging mode.

[0082] For example, in actual use, when the processor 204 obtains its own temperature data of 38°C through the second temperature sensor 206, it determines whether the temperature data of 38°C exceeds the preset temperature threshold corresponding to the high temperature range (36°C-45°C, 35°C). Obviously, 38°C exceeds 35°C, and the processor 204 outputs a first charging control signal to the charging power adjustment module 207. So that the charging power adjustment module 207 executes the first charging mode. In particular, the 5V1A charging mode in the first charging mode is a slow charging mode, and the second charging mode is a fast charging mode with multiple specifications such as 9V2A, 5V3A, 10V2.25A, and 20V5A. In the actual charging process, the specific specification to be used depends on the handshake protocol between the mobile power supply and the external device. This protocol handshake is a prior art and will not be elaborated here.

[0083] If in actual use, the processor 204 obtains its own temperature data of 34°C through the second temperature sensor 206, and determines that the self-temperature data 34°C does not exceed the preset temperature threshold corresponding to the temperature range (36°C-45°C, 35°C), that is, 34°C does not exceed 35°C, then the processor 204 outputs a second charging control signal to the charging power adjustment module based on the situation of not exceeding the preset temperature threshold 35°C, so that the charging power adjustment module executes the second charging mode, that is, the fast charging mode.

[0084] In another usage scenario, before outputting the first charging control signal to the charging power adjustment module, the following third judgment step S304 is also included: judging whether the external temperature data is in the low temperature range; if the external temperature data is in the low temperature range, continuing to judge whether the self-temperature data exceeds the preset temperature threshold corresponding to the low temperature range; if not, outputting the first charging control signal to the charging power adjustment module so that the charging power adjustment module executes the first charging mode; if exceeded, outputting the second charging control signal to the charging power adjustment module according to the preset temperature threshold, so that the charging power adjustment module executes the second charging mode and during the execution of the second charging mode, continuously receiving the self-temperature data and judging whether it exceeds the second preset temperature threshold; if not exceeding the second preset temperature threshold, executing the second charging mode; if exceeding the second preset temperature threshold, switching to the first charging mode.

[0085] In this embodiment, when the external ambient temperature is low, the power bank's own temperature is also low due to the ambient temperature. During charging and discharging, the processor 204 in the power bank obtains external ambient temperature data via the first temperature sensor 205. For example, if the ambient temperature is in the low temperature range of -10°C to 9°C, the preset temperature threshold corresponding to this low temperature range is 16°C. Meanwhile, when the second temperature sensor 206 obtains the power bank's own temperature data, for example, 5°C, the processor 204 determines that the current internal temperature of 5°C is less than the preset temperature threshold of 16°C. The power bank then outputs a first charging control signal to the charging power adjustment module 207, causing it to implement the first charging mode, or slow charging mode. This design is based on the fact that the electrochemical reaction rate within the power bank's battery is significantly affected by temperature in a low-temperature environment. In low-temperature environments, the chemical reaction rate decreases, slowing the ion exchange between the positive and negative electrode materials. Furthermore, the reduced reaction rate reduces the charge transfer efficiency within the battery, resulting in increased internal resistance, which in turn affects the charging efficiency of the power bank. At this point, if the power bank is operating in high-power mode, the battery is more susceptible to damage. Therefore, starting the power bank in slow charging mode helps preserve the battery life.

[0086] When the battery temperature exceeds the preset temperature threshold of 16°C, a second charging control signal is output to the charging power adjustment module based on the preset temperature threshold, causing the charging power adjustment module 207 to execute the second charging mode. During the execution of the second charging mode, the module continuously receives the temperature data and determines whether it exceeds the second preset temperature threshold. It should be noted that the second preset temperature threshold can be set to 45°C based on actual usage needs or the characteristics of the mobile power supply. That is, within 45°C, the charging and discharging operations of the mobile power supply are safe, thereby effectively preventing the mobile power supply from crashing due to excessive temperature. If the temperature does not exceed 45°C, the second charging mode is executed; if the temperature exceeds 45°C, the module switches to the first charging mode.

[0087] That is, in a low temperature environment, the second charging mode is executed when the temperature data is between 16°C and 45°C, and the first charging mode is executed when the temperature data is below 16°C or exceeds 45°C.

[0088] In summary, this technical solution can make full use of various different environments to enable the mobile power supply to output accurate charging power, while improving the safe use of the mobile power supply and effectively avoiding the ineffective consumption of the mobile power supply's electricity.

[0089] In another usage scenario, in step S302: before determining the temperature range of the first device based on the external temperature data, the following first judgment step S305 is included: judging whether the external temperature data is in the temperature threshold list; if the external temperature data belongs to the temperature threshold list, analyzing and processing the temperature range corresponding to the external temperature data and the preset temperature threshold corresponding to the temperature range; if the external temperature data is not in the temperature threshold list, outputting an alarm signal to the charging indication status module.

[0090] It should be understood that, for example, if the external temperature data is 47°C, but the temperature threshold list includes three temperature ranges: a high temperature range of 36°C-45°C, a medium temperature range of 10°C-35°C, and a low temperature range of -10°C-9°C; that is, the temperature range of the temperature threshold list is -10°C-45°C. Since the external temperature data of 47°C exceeds 45°C, it is concluded that the external temperature data is not in the temperature threshold list, and an alarm signal is output to the charging indication status module 208. The charging indication status module 208 is an LED light module that receives signals from the processor 204 and is controlled by the processor 204 to have multiple display states; each display state corresponds to the first charging mode or the second charging mode. For example, the red light flashes in the first charging mode and the blue light flashes in the second charging mode. If the LED module receives an alarm signal, the red and blue lights flash simultaneously to notify the user that the mobile power supply is currently in an abnormal operating state.

[0091] If at this time, the external temperature data is 35°C, then according to steps S301-S304, it is determined that the temperature range corresponding to the external temperature data 35°C is within the medium temperature range of 10°C-35°C, and according to the preset temperature threshold of 40°C corresponding to the medium temperature range, a charging control signal is output according to the self-temperature data transmitted by the second temperature sensor 206, so that the mobile power supply executes the first charging mode or the second charging mode.

[0092] In another usage scenario, the temperature threshold list includes multiple continuous and non-overlapping temperature intervals and preset temperature thresholds corresponding to each temperature interval; wherein the absolute difference between adjacent temperature intervals is a fixed value or a non-fixed value, and the preset temperature threshold corresponding to each temperature interval shows a gradual change rule as the temperature interval changes, and the gradual change rule includes linear gradual change or nonlinear gradual change.

[0093] It should be understood that, for example, the high temperature interval and its corresponding preset temperature threshold mentioned above are (36°C-45°C, 35°C), the medium temperature interval and its corresponding preset temperature threshold are (10°C-35°C, 40°C), and the low temperature interval and its corresponding preset temperature threshold are (-10°C-9°C, 16°C). It should be understood that the absolute difference between the lower limit of 36°C in the high temperature interval and the upper limit of 35°C in the medium temperature interval is 1°C. The preset temperature threshold in the high temperature interval can change in a gradual manner, for example, the preset temperature threshold in the high temperature interval changes linearly between 30°C and 35°C. It is understandable that, for example, in the hot summer, although the overall weather temperature is very high, the weather temperature is still in a changing state within a day, for example, the temperature is different in the morning and evening. Therefore, setting multiple preset temperature thresholds in the same temperature interval will better cope with changing ambient temperatures.

[0094] In this embodiment, the change in the preset temperature threshold is a linear change that increases incrementally. In another embodiment, the change in the preset temperature threshold is a nonlinear gradual change. For example, a corresponding preset temperature threshold is set for each time of day: morning, noon, and evening. For example, if the temperature is cool in the morning and evening, the preset temperature threshold can be set to 33°C, while the temperature is high at noon, the preset temperature threshold can be set to 35°C. Then, the judgment and analysis are performed according to steps S301 to S304 to output the corresponding charging power.

[0095] In order for the mobile power supply to output charging power more accurately according to the changing ambient temperature, the step S303: the step of determining whether the own temperature data exceeds the preset temperature threshold also includes: comparing and determining the own temperature data and the preset temperature threshold at every preset time interval; the preset time interval is any value between 10S-60S.

[0096] It should be understood that since the mobile power supply generates heat during the charging and discharging process, for example, comparing the temperature data of the mobile power supply with the preset temperature threshold once every 10 seconds can cope with the changing external ambient temperature and the heating of the mobile power supply itself to output the charging power more accurately.

[0097] Example 2
