Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a charging control method according to an embodiment of the present invention. The method comprises the following steps:
Step S101, detecting temperature values of a plurality of heating sources in the adapter.
The plurality of heating sources can be all parts capable of heating in the adapter, and parts capable of easily heating can also be selected. In the embodiment of the invention, the plurality of heating sources can comprise any two or more than two of a high-voltage capacitor, a switching tube, a high-frequency transformer, a rectifier, a charging interface, a microprocessor and an adapter shell. The preset time can be detected through experiments according to the temperature change conditions of the adapter in various simulated supposed scenes, and then the reasonable preset time is obtained through analysis. For example, the preset time is 5 minutes, the temperature values of the plurality of heating sources in the adapter are detected every five minutes, and the detected temperature values are stored in the list.
Step S102, judging whether the highest temperature value in the temperature values of the plurality of heating sources reaches a first preset temperature value or not; if yes, go to step S103; if not, go to step S105.
It can be understood that the temperature values of the heat sources may be different, some of the heat sources have high temperatures, and some of the heat sources have low temperatures, but once the temperature value of a certain heat source is too high and reaches a certain threshold, the performance of the adapter may be affected. Therefore, it is necessary to determine whether the highest temperature value among the temperature values of the plurality of heat generation sources reaches a first preset temperature value.
Step S103, sending an instruction for detecting whether the working state of the terminal is in a standby state and whether the electric quantity of the battery is greater than the preset electric quantity 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 a first preset temperature value, an instruction for detecting whether the terminal operating state is in a standby state and whether the battery power is greater than a preset power is sent to the mobile terminal.
And step S104, correspondingly adjusting the charging current output by the adapter according to the detection result returned by the mobile terminal and the corresponding table of the preset temperature range and the preset charging current.
it can be understood that, before the adapter leaves the factory, a correspondence table recording the preset temperature range of the adapter and the preset charging current of the adapter is established through experimental tests. The corresponding table of the preset temperature range and the preset charging current can be determined by testing how much the different charging currents can cause the temperature value of the specified reference heating source in the adapter to rise within the preset time. The preset temperature range is inversely proportional to the preset charging current, namely the higher the temperature is, the smaller the preset charging current is, so that the heat generation of the adapter is reduced.
And S105, correspondingly adjusting the charging current output by the adapter according to the corresponding table of 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 meets the preset condition, the charging current output by the adapter is correspondingly adjusted according to the detection result meeting the preset condition and the corresponding table of the preset temperature range and the preset charging current.

All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.
Referring to fig. 2, fig. 2 is another schematic flow chart of a charging control method according to an embodiment of the present invention. The method comprises the following steps:
Step S201, detecting temperature values of a plurality of heating sources in the adapter.
It will be appreciated that the adapter will heat up during use. For example, when a mobile phone is charged, the adapter may generate heat under the influence of the current intensity output by the adapter and the ambient temperature. For convenience of carrying, users tend to select an adapter having a smaller volume, but when the volume becomes smaller, the heat radiation performance of the adapter becomes worse. During the use process of the adapter, for example, components and parts which are easy to heat comprise a high-voltage capacitor, a switch tube, a high-frequency transformer, a rectifier, a charging interface, a microprocessor and the like.
in the charging process, the temperature values of a plurality of heating sources in the adapter can be detected within preset time. The plurality of heating sources can be all parts capable of heating in the adapter, and parts capable of easily heating can also be selected. In the embodiment of the invention, the plurality of heating sources can comprise any two or more than two of a high-voltage capacitor, a switching tube, a high-frequency transformer, a rectifier, a charging interface, a microprocessor and an adapter shell. The preset time can be detected through experiments according to the temperature change conditions of the adapter in various simulated supposed scenes, and then the reasonable preset time is obtained through analysis. For example, the preset time is 5 minutes, the temperature values of the plurality of heating sources in the adapter are detected every five minutes, and the detected temperature values are stored in the list.
Step S202, judging whether the highest temperature value in the temperature values of the plurality of heating sources reaches a first preset temperature value; if yes, go to step S203; if not, go to step S205.
It can be understood that the temperature values of the heat sources may be different, some of the heat sources have high temperatures, and some of the heat sources have low temperatures, but once the temperature value of a certain heat source is too high and reaches a certain threshold, the performance of the adapter may be affected. Therefore, it is necessary to determine whether the highest temperature value among the temperature values of the plurality of heat generation sources reaches a first preset temperature value.
Step S203, sending an instruction for detecting whether the terminal operating state is in a standby state and whether the battery power is greater than the preset power 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 a first preset temperature value, an instruction for detecting whether the terminal operating state is in a standby state and whether the battery power is greater than a preset power is sent to the mobile terminal.
For example, the first preset temperature value is 50 degrees celsius, for example, if the temperature of the high-voltage capacitors in the plurality of heat sources is detected to be 40 degrees celsius, the temperature of the rectifier is 43 degrees celsius, the temperature of the charging interface is 46 degrees celsius, and the temperature of the microprocessor is 52 degrees celsius, it is determined that the temperature of the microprocessor reaches the first preset temperature value, and an instruction for detecting whether the working state of the terminal is in the standby state and whether the electric quantity of the battery is greater than the preset electric quantity is sent to the mobile terminal.
And step S204, correspondingly adjusting the charging current output by the adapter according to the detection result returned by the mobile terminal and the corresponding table of the preset temperature range and the preset charging current.
It can be understood that, before the adapter leaves the factory, a correspondence table recording the preset temperature range of the adapter and the preset charging current of the adapter is established through experimental tests. The corresponding table of the preset temperature range and the preset charging current can be determined by testing how much the different charging currents can cause the temperature value of the specified reference heating source in the adapter to rise within the preset time. The preset temperature range is inversely proportional to the preset charging current, namely the higher the temperature is, the smaller the preset charging current is, so that the heat generation of the adapter is reduced.
for example, taking an adapter supporting large-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; when the preset temperature range is more than or equal to 40 ℃ and less than 50 ℃, the corresponding preset charging current is 2A; when the preset temperature range is greater than or equal to 30 ℃ and less than 40 ℃, the corresponding preset charging current is 3A; when the preset temperature range is greater than or equal to 10 ℃ and less than 30 ℃, the corresponding preset charging current is 4.5A.
It can be understood that, when the detection result returned by the mobile terminal meets the preset condition, the charging current output by the adapter is correspondingly adjusted according to the detection result meeting the preset condition and the corresponding table of the preset temperature range and the preset charging current.
It is understood that the step S204 is required to perform the adjustment after the mobile terminal completes the pre-charging phase.
In some embodiments, the step S204 may be implemented by steps S2041 to S2043, specifically:
Step S2041, when the terminal working state returned by the mobile terminal is received and is in a standby state and the battery electric quantity is greater than the preset electric quantity, reducing the charging current output by the adapter according to a corresponding table of a preset temperature range and a preset charging current.
For example, taking a mobile phone as an example, the preset electric quantity is 40% of the battery capacity. When the working state of the terminal returned by the mobile phone is in a standby state and the electric quantity of the battery is greater than 40% of the capacity of the battery, the normal use of the user in a period of time can be ensured, for example, the use time of the user for 4 hours can be ensured, then the charging current output by the adapter can be reduced according to a corresponding table of a preset temperature range and a preset charging current, for example, the original 4.5A charging current is adjusted to be 1A for output so as to reduce the heating of a plurality of heating sources in the adapter, and the plurality of heating sources in the adapter slowly cool down after a period of time, so that the situation that the temperature of the adapter is too high to cause the panic of the user or an accident is prevented.
step S2042, when the terminal operating state returned by the mobile terminal is received and is in a non-standby state, maintaining the charging current currently output by the adapter.
For example, taking a mobile phone as an example, the preset electric quantity is 40% of the battery capacity. When the terminal working state returned by the mobile phone is a non-standby state, such as a user making a call, playing a game, or surfing the internet, and no matter whether the battery capacity 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, such as the output charging current is 4.5A, so as to ensure the normal use of the mobile phone.
in some embodiments, when the terminal operating state returned by the mobile terminal is received as a non-standby state and the highest temperature value of the temperature values of the plurality of heat sources reaches a second preset temperature value, the charging current output by the adapter is reduced according to a corresponding table of a preset temperature range and a 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 electric quantity is 40% of the battery capacity. When the terminal working state returned by the mobile phone is a non-standby state, for example, a user is making a call, playing a game or surfing the internet, and the highest temperature value in the temperature values of the plurality of heating sources does not reach a second preset temperature value, the charging current of the adapter is not adjusted no matter whether the electric quantity of the battery is greater than 40% of the capacity of the battery, so that the charging current currently output by the adapter is maintained, and the normal use of the mobile phone is ensured. However, when the temperature was too high, easily burn out the adapter, then when the highest temperature value among the temperature value of a plurality of sources that generate heat reached the second and predetermine the threshold value, for example, the second predetermines the threshold value and is 60 degrees centigrade, reduces according to the corresponding table of predetermineeing temperature range and predetermineeing charging current the charging current of adapter output, for example adjust 4.5A's charging current to 1A exports to reduce the generating heat of a plurality of sources that generate heat in the adapter, make a plurality of sources that generate heat in the adapter slowly cool down after a period, in order to prevent that the temperature is too high and make the adapter take place the damage.
Step S2043, when the terminal operating state returned by the mobile terminal is received and is in a standby state and the battery power is less than or equal to a preset power, maintaining the charging current currently output by the adapter.
for example, taking a mobile phone as an example, the preset electric quantity is 40% of the battery capacity, when the terminal operating state received by the mobile phone is a standby state and the battery electric quantity is not 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, for example, the output charging current is 4.5A, so as to ensure that the battery of the mobile phone is charged as much as possible in a short time, and meet the requirement of a user for charging the charged mobile phone with more electric quantity as possible in a short time.
Step S205, correspondingly adjusting the charging current output by the adapter according to the preset temperature range of the adapter and the corresponding table of 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 charging current output by the adapter is correspondingly adjusted according to the preset temperature range of the adapter and the corresponding table of the preset charging current. 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, the charging current output by the adapter is adjusted to be 4.5A according to the corresponding table of the preset temperature range and the preset charging current, and the corresponding preset charging current is 4.5A.
according to the steps, in the charging process, temperature values of a plurality of heating sources in the adapter are continuously monitored in a preset time period, and the charging current output by the adapter is adjusted correspondingly according to the detected temperature values.
For a clearer understanding of the embodiment of the present invention, please refer to fig. 3, and fig. 3 is a schematic view of an application scenario of a charging control method according to the embodiment of the present invention.
Before the adapter A leaves a factory, a corresponding table of a preset temperature range and a preset current is established.
And when the terminal B needs to be charged, the adapter A is connected with the terminal B. The connection may be a wired connection or a wireless connection. When the adapter A is connected with the terminal B through a charging cable, wired charging is carried out; when the adapter A and the terminal B are connected through the wireless network, wireless charging is carried out.
The adapter A detects temperature values of a plurality of heating sources; the adapter A further judges whether the highest temperature value in the temperature values of the plurality of heating sources reaches a first preset temperature value or not according to the detection result; when the highest temperature value among the temperature values of the plurality of heating sources reaches a first preset temperature value, the adapter A sends an instruction for detecting whether the working state of the terminal is in a standby state or not and whether the electric quantity of the battery is larger than the preset electric quantity or not.
The terminal B detects whether the working state of the terminal is in a standby state or not and whether the electric quantity of the battery is greater than the preset electric quantity or not; and sending the detection result of the terminal B to the adapter A.
And the adapter A correspondingly adjusts the charging current output by the adapter A according to the detection result returned by the terminal B and the corresponding table of the preset temperature range and the preset current.
According to the embodiment of the invention, by detecting the temperature values of a plurality of heating sources in the adapter, when the highest temperature value in the temperature values of the plurality of heating sources is judged to reach a first preset temperature value, an instruction for detecting whether the working state of the terminal is in a standby state or not and whether the electric quantity of the battery is larger than the preset electric quantity or not is sent to the mobile terminal, and the charging current output by the adapter is correspondingly adjusted according to the detection result returned by the mobile terminal and the corresponding table of the preset temperature range and the preset charging current, so that the heating of the adapter can be reduced, the quick charging can be realized, the hardware performance of the adapter is protected, the charging temperature of the adapter is controlled within a reasonable range, and the requirement of a user on charging more electric quantity of the charged terminal in a short time is met.
An embodiment of the present invention further provides a charging control device, as shown in fig. 4, and fig. 4 is a schematic structural diagram of the charging control device according to the embodiment of the present invention. The charging control device 30 includes a detection module 31, a determination module 32, a sending module 33, and an adjustment module 34.
The detection module 31 is configured to detect temperature values of a plurality of heat sources in the adapter.

In the embodiment of the invention, the plurality of heating sources can comprise any two or more than two of a high-voltage capacitor, a switching tube, a high-frequency transformer, a rectifier, a charging interface, a microprocessor and an adapter shell.

For example, the preset time is 5 minutes, the temperature values of the plurality of heating sources in the adapter are detected every five minutes, and the detected temperature values are stored in the list.
The judging module 32 is configured to judge whether a highest temperature value of the temperature values of the plurality of heat sources reaches a first preset temperature value.
It can be understood that the temperature values of the heat sources may be different, some of the heat sources have high temperatures, and some of the heat sources have low temperatures, but once the temperature value of a certain heat source is too high and reaches a certain threshold, the performance of the adapter may be affected. Therefore, it is necessary to determine whether the highest temperature value of the temperature values of the plurality of heat sources reaches the first preset temperature value by the determination module 32.

the adjusting module 34 is configured to correspondingly adjust the charging current output by the adapter according to the detection result returned by the mobile terminal and the corresponding table of the preset temperature range and the preset charging current.
It can be understood that, before the adapter leaves the factory, a correspondence table recording the preset temperature range of the adapter and the preset charging current of the adapter is established through experimental tests. The corresponding table of the preset temperature range and the preset charging current can be determined by testing how much the different charging currents can cause the temperature value of the specified reference heating source in the adapter to rise within the preset time. The preset temperature range is inversely proportional to the preset charging current, namely the higher the temperature is, the smaller the preset charging current is, so that the heat generation of the adapter is reduced.
For example, taking an adapter supporting large-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; when the preset temperature range is more than or equal to 40 ℃ and less than 50 ℃, the corresponding preset charging current is 2A; when the preset temperature range is greater than or equal to 30 ℃ and less than 40 ℃, the corresponding preset charging current is 3A; when the preset temperature range is greater than or equal to 10 ℃ and less than 30 ℃, the corresponding preset charging current is 4.5A.
It can be understood that, when the detection result returned by the mobile terminal meets the preset condition, the adjusting module 34 correspondingly adjusts the charging current output by the adapter according to the detection result meeting the preset condition and the corresponding table of the preset temperature range and the preset charging current.
The adjusting module 34 needs to perform the adjusting operation after the mobile terminal completes the pre-charging phase.
in some embodiments, the adjusting module 34 is further configured to reduce the charging current output by the adapter according to a mapping table between a preset temperature range and a preset charging current when the terminal operating state returned by the mobile terminal is a standby state and the battery power is greater than a preset power.
For example, taking a mobile phone as an example, the preset electric quantity is 40% of the battery capacity. When the terminal working state that the mobile phone returns is received and is standby state, just when battery power is greater than 40% of battery capacity, can guarantee the normal use of user in a period of time, for example can guarantee user 4 hours 'live time, then adjusting module 34 can reduce according to the corresponding table of presetting the temperature range and presetting charging current the charging current of adapter output, for example adjust 4.5A's charging current originally to 1A and export to reduce the generating heat of a plurality of heating sources in the adapter, make a plurality of heating sources in the adapter slowly cool down after a period of time, in order to prevent that the adapter temperature is too high and arouse user panic, perhaps take place accident.
In some embodiments, the adjusting module 34 is further configured to maintain the charging current currently output by the adapter when the terminal operating state returned by the mobile terminal is received and is a non-standby state.
For example, taking a mobile phone as an example, the preset electric quantity is 40% of the battery capacity. When the terminal operating state returned by the mobile phone is a non-standby state, such as when the user is making a call, playing a game, or surfing the internet, regardless of whether the battery capacity is greater than 40% of the battery capacity, the adjusting module 34 does not adjust the charging current of the adapter to maintain the charging current currently output by the adapter, such as the output charging current is 4.5A, so as to ensure the normal use of the mobile phone.
In some embodiments, the adjusting module 34 is further configured to reduce the charging current output by the adapter according to a mapping table between a preset temperature range and a preset charging current when the terminal operating state returned by the mobile terminal is a non-standby state and a highest temperature value of the temperature values of the plurality of heat sources reaches a second preset temperature value. 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 electric quantity is 40% of the battery capacity. When the terminal working state returned by the mobile phone is a non-standby state, for example, a user is making a call, playing a game or surfing the internet, and the highest temperature value in the temperature values of the plurality of heating sources does not reach a second preset temperature value, no matter whether the electric quantity of the battery is greater than 40% of the capacity of the battery, the adjusting module 34 does not adjust the charging current of the adapter so as to maintain the charging current currently output by the adapter, so as to ensure the normal use of the mobile phone. However, when the temperature was too high, burn out the adapter easily, then when the highest temperature value among the temperature value of a plurality of sources that generate heat reached the second and predetermine the threshold value, for example, the second predetermines the threshold value and is 60 degrees centigrade, adjustment module 34 reduces according to predetermineeing the temperature range and predetermine charging current's corresponding table the charging current of adapter output, for example adjust 4.5A's charging current into 1A and export to reduce the generating heat of a plurality of sources that generate heat in the adapter, make a plurality of sources that generate heat in the adapter slowly cool down after a period of time, in order to prevent that the temperature is too high and make the adapter take place to damage.
In some embodiments, the adjusting module 34 is further configured to maintain the charging current currently output by the adapter when the terminal operating state returned by the mobile terminal is received as a standby state and the battery power is less than or equal to a preset power.
for example, in the case of a mobile phone, the preset amount of power is 40% of the battery capacity. When the terminal working state returned by the mobile phone is received as a standby state and the battery capacity is not greater than 40% of the battery capacity, the adjusting 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 mobile phone battery is charged as much as possible in a short time, and meet the requirement of a user on charging more electric quantity of the charged mobile phone in a short time.
In some embodiments, the adjusting module 34 is further configured to correspondingly adjust the charging current output by the adapter according to a preset temperature range of the adapter and a preset charging current mapping table when a highest temperature value of the temperature values of the plurality of heat sources does not reach a first preset temperature value.
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, the adjusting module 34 adjusts the charging current output by the adapter to be 4.5A according to the corresponding table of the preset temperature range and the preset charging current, where the corresponding preset charging current is 4.5A.
