Please refer to FIG. 1 , which is a schematic flowchart of a charging control method according to an embodiment of the present invention. The method includes:

Step S101, detecting temperature values of multiple heat sources in the adapter.

Wherein, the plurality of heat sources may be all components in the adapter that can generate heat, or components that are easy to generate heat may be selected. In the embodiment of the present invention, the plurality of heat sources may include any two or more of a high-voltage capacitor, a switch tube, a high-frequency transformer, a rectifier, a charging interface, a microprocessor, and an adapter housing. For the preset time, the temperature change of the adapter in various simulated scenarios can be detected through experiments, and then a reasonable preset time can be obtained through analysis. For example, the preset time is 5 minutes, and the temperature values of multiple heat sources in the adapter are detected every five minutes, and each detected temperature value is stored in a list.

Step S102, it is judged whether the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value; if so, step S103 is performed; if not, step S105 is performed.

It is understandable that the temperature value of each heat source will be different. Some heat sources have high temperature and some heat sources have low temperature. However, once the temperature value of a heat source is too high and reaches a certain threshold, it may affect the adapter. performance. Therefore, it is necessary to judge whether the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value.

Step S103, sending an instruction to detect whether the terminal working state is in a standby state and to detect whether the battery power is greater than a preset power level to the mobile terminal.

It can be understood that, when the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value, the detection of whether the working state of the terminal is in the standby state and the detection of whether the battery power is greater than the preset power is sent to the mobile terminal. instruction.

Step S104 , according to the detection result returned by the mobile terminal and the corresponding table of the preset temperature range and the preset charging current, adjust the charging current output by the adapter correspondingly.

It can be understood that, before the adapter leaves the factory, a correspondence table between the preset temperature range of the adapter and the preset charging current of the adapter is established through experimental tests. The correspondence table between the preset temperature range and the preset charging current can be determined by testing how much the temperature value of the designated reference heat source in the adapter rises due to different charging currents within a preset time. The preset temperature range is inversely proportional to the preset charging current, that is, the higher the temperature, the smaller the preset charging current, so as to reduce the heat generation of the adapter.

Step S105 , correspondingly adjust the charging current output by the adapter according to the correspondence table between the preset temperature range of the adapter and the preset charging current.

It can be understood that, when the detection result returned by the mobile terminal satisfies the preset condition, the output value of the adapter is adjusted correspondingly according to the detection result satisfying the preset condition and the correspondence table between the preset temperature range and the preset charging current. recharging current.

In some embodiments, the adjusting the charging current output by the adapter according to the detection result returned by the mobile terminal and the corresponding table between the preset temperature range and the preset charging current, includes:

When it is received that the terminal working state returned by the mobile terminal is a standby state, and the battery power is greater than a preset power level, the charging output by the adapter is reduced according to the correspondence table between the preset temperature range and the preset charging current current.

In some embodiments, the adjusting the charging current output by the adapter according to the detection result returned by the mobile terminal and the corresponding table between the preset temperature range and the preset charging current, includes:

When it is received that the terminal working state returned by the mobile terminal is a standby state, and the battery power is less than a preset power, the charging current currently output by the adapter is maintained.

In some embodiments, the method further includes:

When the highest temperature among the temperature values of the plurality of heat sources does not reach the first preset temperature, the charging current output by the adapter is adjusted correspondingly according to the corresponding table between the preset temperature range of the adapter and the preset charging current.

All the above-mentioned optional technical solutions can be combined arbitrarily to form optional embodiments of the present invention, which will not be repeated here.

Please refer to FIG. 2 , which is another schematic flowchart of a charging control method according to an embodiment of the present invention. The method includes:

Step S201, detecting temperature values of multiple heat sources in the adapter.

Understandably, the adapter heats up during use. For example, when a mobile phone is charged, the adapter will heat up due to the influence of the current intensity output by the adapter and the ambient temperature. For portability, users tend to choose adapters with smaller volumes, but when the volume becomes smaller, the heat dissipation performance of the adapters will deteriorate. During the use of the adapter, for example, components that are prone to heat include high-voltage capacitors, switching tubes, high-frequency transformers, rectifiers, charging interfaces, and microprocessors.

During the charging process, the temperature values of multiple heat sources in the adapter can be detected within a preset time. The plurality of heat sources may be all components in the adapter that can generate heat, or components that are prone to heat may be selected. In the embodiment of the present invention, the plurality of heat sources may include any two or more of a high-voltage capacitor, a switch tube, a high-frequency transformer, a rectifier, a charging interface, a microprocessor, and an adapter housing. For the preset time, the temperature change of the adapter in various simulated scenarios can be detected through experiments, and then a reasonable preset time can be obtained through analysis. For example, the preset time is 5 minutes, and the temperature values of multiple heat sources in the adapter are detected every five minutes, and each detected temperature value is stored in a list.

Step S202 , judging whether the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value; if so, execute step S203 ; if not, execute step S205 .

It is understandable that the temperature value of each heat source will be different. Some heat sources have high temperature and some heat sources have low temperature. However, once the temperature value of a heat source is too high and reaches a certain threshold, it may affect the adapter. performance. Therefore, it is necessary to judge whether the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value.

Step S203, sending an instruction to detect whether the terminal working state is in a standby state and to detect whether the battery power is greater than a preset power level to the mobile terminal.

It can be understood that, when the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value, the detection of whether the working state of the terminal is in the standby state and the detection of whether the battery power is greater than the preset power is sent to the mobile terminal. instruction.

For example, the first preset temperature value is 50 degrees Celsius. For example, it is detected that the temperature of the high-voltage capacitors in the multiple heat sources is 40 degrees Celsius, the temperature of the rectifier is 43 degrees Celsius, the temperature of the charging interface is 46 degrees Celsius, and the microprocessor If the temperature is 52 degrees Celsius, it is determined that the temperature of the microprocessor reaches the first preset temperature value, and instructions are sent to the mobile terminal to detect whether the terminal operating state is in a standby state and to detect whether the battery power is greater than the preset power level.

Step S204 , according to the detection result returned by the mobile terminal and the corresponding table of the preset temperature range and the preset charging current, adjust the charging current output by the adapter correspondingly.

It can be understood that, before the adapter leaves the factory, a correspondence table between the preset temperature range of the adapter and the preset charging current of the adapter is established through experimental tests. The correspondence table between the preset temperature range and the preset charging current can be determined by testing how much the temperature value of the designated reference heat source in the adapter rises due to different charging currents within a preset time. The preset temperature range is inversely proportional to the preset charging current, that is, the higher the temperature, the smaller the preset charging current, so as to reduce the heat generation of the adapter.

For example, taking an adapter that supports high-current charging as an example, for example, when the maximum charging current is 4.5A (Ampere), and the preset temperature range is greater than or equal to 50 degrees Celsius, the corresponding preset charging current is 1A; the preset temperature range is greater than or equal to 1A. or equal to 40 degrees Celsius and less than 50 degrees Celsius, the corresponding preset charging current is 2A; when the preset temperature range is greater than or equal to 30 degrees Celsius and less than 40 degrees Celsius, the corresponding preset charging current is 3A; When it is equal to or equal to 10 degrees Celsius and less than 30 degrees Celsius, the corresponding preset charging current is 4.5A.

It can be understood that, when the detection result returned by the mobile terminal satisfies the preset condition, the output value of the adapter is adjusted correspondingly according to the detection result satisfying the preset condition and the correspondence table between the preset temperature range and the preset charging current. recharging current.

It can be understood that, in the step S204, the adjustment action can be performed only after the mobile terminal completes the pre-charging stage.

In some implementation manners, the step S204 may be implemented through steps S2041 to S2043, specifically:

Step S2041, when the terminal working state returned by the mobile terminal is received as a standby state, and the battery power is greater than a preset power, reduce the adapter according to the corresponding table of the preset temperature range and the preset charging current output charge current.

For example, taking a mobile phone as an example, the preset power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is the standby state, and the battery power is greater than 40% of the battery capacity, the normal use of the user for a period of time can be guaranteed, for example, the user can be guaranteed 4 hours of use time, then Reduce the charging current output by the adapter according to the corresponding table between the preset temperature range and the preset charging current, for example, adjust the original 4.5A charging current to 1A for output, so as to reduce the heat generated by the multiple heat sources in the adapter, so that the The multiple heat sources in the adapter cool down slowly after a period of time to prevent the adapter temperature from being too high and causing user panic or accidents.

Step S2042, when it is received that the terminal working state returned by the mobile terminal is a non-standby state, maintain the charging current currently output by the adapter.

For example, taking a mobile phone as an example, the preset power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is non-standby, such as the user is making a call, playing games, or surfing the Internet, regardless of whether the battery power is greater than 40% of the battery capacity, the charging current of the adapter will not be adjusted to maintain The current output charging current of the adapter, for example, the output charging current is 4.5A, so as to ensure the normal use of the mobile phone.

In some embodiments, when the terminal working state returned by the mobile terminal is non-standby state, and the highest temperature value among the temperature values of the plurality of heat sources reaches the second preset temperature value, according to the preset Setting the corresponding table between the temperature range and the preset charging current reduces the charging current output by the adapter. Wherein, the second preset temperature value is greater than the first preset temperature value.

For example, taking a mobile phone as an example, the preset power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is non-standby state, for example, the user is making a call, playing games, or surfing the Internet, and the highest temperature value among the temperature values of the plurality of heat sources does not reach the second preset temperature value, Regardless of whether the battery power is greater than 40% of the battery capacity, the charging current of the adapter is not adjusted to maintain the charging current currently output by the adapter to ensure the normal use of the mobile phone. However, when the temperature is too high, it is easy to burn the adapter, and when the highest temperature value among the temperature values of the plurality of heat sources reaches the second preset threshold, for example, the second preset threshold is 60 degrees Celsius, according to The corresponding table between the preset temperature range and the preset charging current reduces the charging current output by the adapter. For example, the original 4.5A charging current is adjusted to 1A for output, so as to reduce the heat generated by the multiple heat sources in the adapter and make the adapter After a period of time, the multiple heat sources inside will gradually cool down to prevent the adapter from being damaged due to excessive temperature.

Step S2043, when the terminal working state returned by the mobile terminal is a standby state, and the battery power is less than or equal to a preset power, maintain the charging current currently output by the adapter.

For example, taking a mobile phone as an example, the preset power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is a standby state, and the battery power is not greater than 40% of the battery capacity, the adapter will not be charged. The charging current of the adapter is adjusted to maintain the current output charging current of the adapter. For example, the output charging current is 4.5A to ensure that the mobile phone battery is charged as much as possible in a short period of time to meet the user's demand for the charged battery. The need to charge the phone as much as possible in a short period of time.

Step S205, correspondingly adjust the charging current output by the adapter according to the correspondence table between the preset temperature range of the adapter and the preset charging current.

It can also be understood that when the highest temperature value among the temperature values of the plurality of heat sources does not reach the first preset temperature value, the corresponding adjustment is made according to the corresponding table between the preset temperature range of the adapter and the preset charging current. The charging current output by the adapter. For example, when the highest temperature value among the temperature values of the plurality of heat sources is 23 degrees Celsius, and the corresponding preset temperature range is greater than or equal to 10 degrees Celsius and less than 30 degrees Celsius, then charging according to the preset temperature range and the preset temperature range According to the corresponding table of current, the corresponding preset charging current is 4.5A, then the charging current output by the adapter is adjusted to be 4.5A.

According to the above steps, during the charging process, the temperature values of multiple heat sources in the adapter are continuously monitored within a preset time period, and the charging current output by the adapter is repeatedly adjusted according to the detected temperature values.

For a clearer understanding of the embodiment of the present invention, please refer to FIG. 3 , which is a schematic diagram of an application scenario of a charging control method provided by an embodiment of the present invention.

Before the adapter A leaves the factory, a correspondence table between the preset temperature range and the preset current is established.

When terminal B needs to be charged, adapter A establishes a connection with terminal B. Wherein, the connection may be a wired connection or a wireless connection. When adapter A and terminal B are connected through a charging cable, wired charging is used; when adapter A and terminal B are connected through a wireless network, wireless charging is used.

Adapter A detects the temperature values of multiple heat sources; adapter A further determines whether the highest temperature value among the temperature values of the multiple heat sources reaches the first preset temperature value according to the detection results; when the temperature of the multiple heat sources When the highest temperature value among the values reaches the first preset temperature value, the adapter A sends an instruction to detect whether the terminal working state is in a standby state and to detect whether the battery power is greater than the preset power level.

The terminal B detects whether the working state of the terminal is in the standby state and whether the battery power is greater than the preset power; and sends the detection result of the terminal B to the adapter A.

The adapter A adjusts the charging current output by the adapter A according to the detection result returned by the terminal B and the corresponding table between the preset temperature range and the preset current.

In the embodiment of the present invention, the temperature values of multiple heat sources in the adapter are detected, and when it is determined that the highest temperature value among the temperature values of the multiple heat sources reaches the first preset temperature value, the detection is sent to the mobile terminal to detect whether the terminal is working. In the standby state and the instruction to detect whether the battery power is greater than the preset power, the charging current output by the adapter can be adjusted according to the detection result returned by the mobile terminal and the corresponding table between the preset temperature range and the preset charging current. It can reduce the heat of the adapter and realize fast charging. While protecting the hardware performance of the adapter, the charging temperature of the adapter is controlled within a reasonable range, and the user's demand for charging the terminal to be charged as much as possible in a short period of time is satisfied. .

An embodiment of the present invention further provides a charging control device, as shown in FIG. 4 , which is a schematic structural diagram of a charging control device provided by an embodiment of the present invention. The charging control device 30 includes a detection module 31 , a judgment module 32 , a transmission module 33 , and an adjustment module 34 .

The detection module 31 is used to detect the temperature values of multiple heat sources in the adapter.

Understandably, the adapter heats up during use. For example, when a mobile phone is charged, the adapter will heat up due to the influence of the current intensity output by the adapter and the ambient temperature. For portability, users tend to choose adapters with smaller volumes, but when the volume becomes smaller, the heat dissipation performance of the adapters will deteriorate. During the use of the adapter, for example, components that are prone to heat include high-voltage capacitors, switching tubes, high-frequency transformers, rectifiers, charging interfaces, and microprocessors.

During the charging process, the detection module 31 can detect the temperature values of multiple heat sources in the adapter within a preset time. The plurality of heat sources may be all components in the adapter that can generate heat, or components that are prone to heat may be selected. In the embodiment of the present invention, the plurality of heat sources may include any two or more of a high-voltage capacitor, a switch tube, a high-frequency transformer, a rectifier, a charging interface, a microprocessor, and an adapter housing. For the preset time, the temperature change of the adapter in various simulated scenarios can be detected through experiments, and then a reasonable preset time can be obtained through analysis. For example, the preset time is 5 minutes, and the temperature values of multiple heat sources in the adapter are detected every five minutes, and each detected temperature value is stored in a list.

The judging module 32 is configured to judge whether the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value.

It is understandable that the temperature value of each heat source will be different. Some heat sources have high temperature and some heat sources have low temperature. However, once the temperature value of a heat source is too high and reaches a certain threshold, it may affect the adapter. performance. Therefore, it is necessary to use the judgment module 32 to judge whether the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value.

The sending module 33 is configured to send an instruction to the mobile terminal to detect whether the working state of the terminal is in the standby state and to detect whether the battery power is greater than the preset power.

It can be understood that when the highest temperature value among the temperature values of the plurality of heat sources reaches the first preset temperature value, the sending module 33 sends the mobile terminal to detect whether the working state of the terminal is in the standby state and to detect the battery level. Whether the command is greater than the preset power.

For example, the first preset temperature value is 50 degrees Celsius. For example, the detection module 31 detects that the temperature of the high-voltage capacitors in the multiple heat sources is 40 degrees Celsius, the temperature of the rectifier is 43 degrees Celsius, and the temperature of the charging interface is 46 degrees Celsius. Celsius, the temperature of the microprocessor is 52 degrees Celsius, the judgment module 32 determines that the temperature of the microprocessor reaches the first preset temperature value, and the sending module 33 sends to the mobile terminal to detect whether the working state of the terminal is in standby Status and instructions to detect if the battery level is greater than the preset level.

The adjustment module 34 is configured to adjust the charging current output by the adapter according to the detection result returned by the mobile terminal and the corresponding table between the preset temperature range and the preset charging current.

It can be understood that, before the adapter leaves the factory, a correspondence table between the preset temperature range of the adapter and the preset charging current of the adapter is established through experimental tests. The correspondence table between the preset temperature range and the preset charging current can be determined by testing how much the temperature value of the designated reference heat source in the adapter rises due to different charging currents within a preset time. The preset temperature range is inversely proportional to the preset charging current, that is, the higher the temperature, the smaller the preset charging current, so as to reduce the heat generation of the adapter.

For example, taking an adapter that supports high-current charging as an example, for example, when the maximum charging current is 4.5A (Ampere), and the preset temperature range is greater than or equal to 50 degrees Celsius, the corresponding preset charging current is 1A; the preset temperature range is greater than or equal to 1A. or equal to 40 degrees Celsius and less than 50 degrees Celsius, the corresponding preset charging current is 2A; when the preset temperature range is greater than or equal to 30 degrees Celsius and less than 40 degrees Celsius, the corresponding preset charging current is 3A; When it is equal to or equal to 10 degrees Celsius and less than 30 degrees Celsius, the corresponding preset charging current is 4.5A.

It can be understood that when the detection result returned by the mobile terminal satisfies the preset condition, the adjustment module 34 adjusts correspondingly according to the detection result that satisfies the preset condition and the correspondence table between the preset temperature range and the preset charging current. The charging current output by the adapter.

The adjustment module 34 can perform the adjustment action only after the mobile terminal completes the pre-charging stage.

In some embodiments, the adjustment module 34 is further configured to, when the terminal working state returned by the mobile terminal is a standby state and the battery power is greater than a preset power, according to the preset temperature range and the preset power. Setting the corresponding table of charging current reduces the charging current output by the adapter.

For example, taking a mobile phone as an example, the preset power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is the standby state, and the battery power is greater than 40% of the battery capacity, the normal use of the user can be guaranteed for a period of time. The adjustment module 34 can reduce the charging current output by the adapter according to the corresponding table between the preset temperature range and the preset charging current, for example, adjust the original 4.5A charging current to 1A for output, so as to reduce the multiple heat generation in the adapter. After a period of time, the multiple heat sources in the adapter will slowly cool down, so as to prevent the adapter temperature from being too high and causing user panic or accidents.

In some embodiments, the adjustment module 34 is further configured to maintain the charging current currently output by the adapter when the terminal working state returned by the mobile terminal is non-standby state.

For example, taking a mobile phone as an example, the preset power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is non-standby, for example, the user is making a call, playing games, or surfing the Internet, regardless of whether the battery power is greater than 40% of the battery capacity, the adjustment module 34 does not adjust the charging current of the adapter. Adjust to maintain the current output charging current of the adapter, for example, the output charging current is 4.5A to ensure the normal use of the mobile phone.

In some embodiments, the adjustment module 34 is further configured to receive the terminal working state returned by the mobile terminal is a non-standby state, and the highest temperature value among the temperature values of the plurality of heat sources reaches the first temperature value. When there are two preset temperature values, the charging current output by the adapter is reduced according to the correspondence table between the preset temperature range and the preset charging current. Wherein, the second preset temperature value is greater than the first preset temperature value.

For example, taking a mobile phone as an example, the preset power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is non-standby state, for example, the user is making a call, playing games, or surfing the Internet, and the highest temperature value among the temperature values of the plurality of heat sources does not reach the second preset temperature value, Regardless of whether the battery power is greater than 40% of the battery capacity, the adjustment module 34 does not adjust the charging current of the adapter to maintain the charging current currently output by the adapter to ensure the normal use of the mobile phone. However, when the temperature is too high, it is easy to burn out the adapter, and when the highest temperature value among the temperature values of the plurality of heat sources reaches the second preset threshold, for example, the second preset threshold is 60 degrees Celsius, so The adjustment module 34 reduces the charging current output by the adapter according to the corresponding table between the preset temperature range and the preset charging current, for example, adjusting the original 4.5A charging current to 1A for output, so as to reduce the multiple heat sources in the adapter After a period of time, the multiple heat sources in the adapter will slowly cool down to prevent the adapter from being damaged due to excessive temperature.

In some embodiments, the adjustment module 34 is further configured to maintain the current state of the adapter when the terminal operating state returned by the mobile terminal is a standby state and the battery power is less than or equal to a preset power level. output charge current.

For example, taking a mobile phone as an example, the preset power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is the standby state, and the battery power is not greater than 40% of the battery capacity, the adjustment module 34 does not adjust the charging current of the adapter to maintain the charging current currently output by the adapter For example, the output charging current is 4.5A, so as to ensure that the battery of the mobile phone can be charged as much as possible in a short period of time, so as to meet the user's demand for charging the mobile phone to be charged as much as possible in a short period of time.
