For example, the charging parameter set by the user may be fast charging, medium-speed charging, slow charging, or the like, or may also be low-power charging, high-power charging, or the like, or may be charging power, and a specific form of the charging parameter is not limited herein.

In the embodiment of the application, the target charging power is determined based on the current state information of the terminal, for example, the battery temperature, the battery electric quantity, the charging parameter set by the user, and the like, so that the current charging power of the terminal is automatically adjusted or passively adjusted based on the current state information of the terminal, the influence of the charging speed and the heating degree on the use of the terminal by the user is balanced, and the charging experience of the user is improved. For example, the current charging power of the terminal may be automatically adjusted according to current state information of the terminal, such as battery power, battery temperature, and the like, that is, the target charging power is used to charge the battery assembly; for another example, the current charging power of the terminal may be passively adjusted according to the charging parameters set by the user.
The embodiment of the present application provides another charging method, which includes steps S201 to S207:
s201, when the condition that the terminal is charged is detected to be met, receiving a voice charging instruction, wherein the voice charging instruction is used for indicating the terminal to charge the battery pack according to the charging parameters indicated by the voice charging instruction;

And if the voice instruction received by the terminal comprises voice information related to charging, determining that the received voice instruction is a voice charging instruction.

S202, determining a charging parameter set by the user based on the voice charging instruction;
generally, the content of the voice charging instruction is identified to obtain text content, and then the charging parameter is extracted from the text content. For example, if the text content is "50W charging", it may be determined that the charging parameter set by the user is "50W"; for another example, if the text content is "i want to charge quickly", the charging parameter set by the user may be determined to be "quick charge".

The embodiment of the present application provides another charging method, including steps S301 to S308:
s301, when the condition that the terminal is charged is detected to be met, displaying a preset charging power setting interface, wherein the charging power setting interface comprises at least one charging power gear which can be selected by the user;
for example, when it is determined that the terminal is electrically connected to the power adapter, the charging power setting interface is displayed, so that a user can select the currently desired charging power on the charging power setting interface; in other embodiments, the user may trigger the display of the charging power setting interface by clicking a button for invoking the charging power setting interface. For example, as shown in fig. 2A, a key 20 for calling the charging power setting interface may be displayed in an application interface 21 with an application program of "set"; as shown in fig. 2B, the button 20 may be hidden in the notification bar 22, and the user may call up the notification bar 22 through a pull-up operation or a pull-down operation, so as to click the button 20 to trigger the display of the charging power setting interface. For the terminal, if an operation instruction is received, the operation instruction is used for instructing the terminal to display the charging power setting interface, and the charging power setting interface is displayed based on the second operation instruction.
In practical applications, for example, as shown in fig. 3A, the charging power setting interface 31 includes 3 charging power steps of "high power charging", "medium power charging", and "low power charging". As shown in fig. 3B, the charging power setting interface 32 includes 9 charging power steps of 20W, 30W, 40W, 50W, 60W, 70W, 80W, 90W, and 100W.
S302, receiving a selection instruction on the charging power setting interface, wherein the selection instruction is used for instructing the terminal to charge the battery pack according to the charging parameters indicated by the selection instruction;
s303, determining the charging parameters set by the user based on the selection instruction;
generally, the charging power gear selected by the user (i.e., the charging parameter set by the user) can be determined by determining the location on the charging power setting interface where the selection instruction is received.
It should be noted that steps S301 to S303 are another implementation example of "acquiring the charging parameter set by the user".
S304, determining a first charging power corresponding to the charging parameter based on the charging parameter set by the user;
s305, acquiring the current battery temperature and the current battery power of the terminal;
s306, determining a second charging power based on the battery temperature and the battery electric quantity, wherein the second charging power is the maximum safe charging power which can be currently accepted by the battery assembly;
s307, determining the target charging power based on the first charging power and the second charging power;
and S308, charging the battery assembly of the terminal by using the target charging power.
In the embodiment of the application, a user can set the charging parameters through the charging power setting interface, so that the current charging power of the terminal is controlled by the user, and the requirements of the user on the charging speed and the heating degree under different application scenes are met.
The embodiment of the present application provides another charging method, including steps S401 to S409:
s401, when the condition that the terminal is charged is detected to be met, acquiring current state information of the terminal;
s402, determining a second charging power based on the battery temperature and the battery electric quantity, wherein the second charging power is the maximum safe charging power which can be currently accepted by the battery assembly;
s403, determining whether the current state information comprises the charging parameters set by the user; if yes, go to step S404; otherwise, go to step S406;
s404, determining first charging power corresponding to the charging parameters based on the charging parameters set by the user;
for example, if the charging parameter set by the user is not a specific charging power value, but a parameter indicating a charging speed (e.g., fast charging, slow charging, low-power charging, high-power charging, etc.), the first charging power corresponding to the charging parameter set by the user may be determined according to a preset power mapping table. For example, as shown in table 1, the first charging power corresponding to fast charging is 90 watts (Watt, W), the first charging power corresponding to medium charging is 60W, the first charging power corresponding to slow charging is 30W, and when the charging parameter set by the user is fast charging, the first charging power corresponding to fast charging is determined to be 90W from table 1.
TABLE 1
| Charging parameter | First charging power (watt) |
| Fast charging | 90 |
| Medium-speed charging | 60 |
| Charging at a slow rate | 30 |
S405, determining the target charging power based on the first charging power and the second charging power, and then entering a step S409;
it is understood that the charging parameter set by the user may not be within the currently allowed charging power range of the terminal, and the charging parameter set by the user may not satisfy the current charging condition of the terminal, for example, the first charging power set by the user is greater than the currently allowed maximum safe charging power of the battery assembly, and if the battery assembly is charged with the first charging power set by the user at this time, the cell performance of the battery assembly may be damaged, and even the cell may explode. Therefore, here, determining the target charging power based on the first charging power and the second charging power can ensure charging safety on the premise of realizing automatic adjustment of the charging power and equalizing the influence of the charging speed and the heating degree on the use of the terminal by the user.
In addition, the first charging power set by the user may not meet the current charging condition of the battery assembly, for example, the first charging power set by the user is greater than the currently allowed maximum safe charging power of the battery assembly, and if the battery assembly is charged with the first charging power set by the user at this time, the cell performance of the battery assembly may be damaged, and even the cell may explode.
It should be noted that steps S404 and S405 are an implementation example of "determining the target charging power based on the current state information".
For example, in other embodiments, for step S405, the determining the target charging power based on the first charging power and the second charging power may include: comparing the first charging power with the second charging power; determining the first charging power as the target charging power if the first charging power is less than the second charging power; determining the second charging power as the target charging power if the first charging power is greater than or equal to the second charging power.
S406, acquiring other current state information of the terminal, wherein the other current state information at least comprises one of the following information: the current running state and the connection mode of the terminal and the power adapter;
it can be understood that the current operation state of the terminal is positively correlated with the energy consumption generated by the terminal, for example, the more applications currently operated by the terminal or the larger the memory overhead of the terminal is, the more the load consumption capability of the terminal is, and the more serious the heating phenomenon is. In other embodiments, the memory overhead of the terminal may be obtained, and the current operating state of the terminal may be characterized by the memory overhead.
Currently, the connection between the terminal and the power adapter is usually made by the power adapter 40 through a power cord 41 and a terminal 42, as shown in fig. 4A. In the embodiment of the present application, another connection manner is provided, as shown in fig. 4B, the power adapter 40 is electrically connected to the terminal 42 through the heat dissipation device 43, so that the terminal 42 being charged can be dissipated through the heat dissipation device 43, thereby timely reducing the heat generated by the terminal 42 during the charging process. In practical applications, the heat dissipation device 43 may be a fan, a refrigeration device, or the like. After the heat sink 43 is inserted into the charging interface of the terminal 42, the heat sink 43 may send a prompt signal to the terminal 42 through a wireless communication link (e.g., a bluetooth link, a WIFI link, an NFC link, etc.) with the terminal 42 to inform that the device, which is currently inserted into the terminal 42, of the terminal 42 is a heat sink. For example, the prompt signal includes an identification code of the heat sink 43, and the terminal 42 can determine whether to establish electrical connection with the power adapter through the heat sink according to the received prompt signal.
As shown in fig. 4B, the heat sink 43 is provided with a plug that mates with the charging interface of the terminal 42, for example, the charging interface of the terminal 42 has a power supply pin VBUS, a D + pin, a D-pin, and a ground pin GND, and correspondingly, the plug of the heat sink 43 also has these four pins. The plug on the heat sink 43 is connected with the terminal 42, so that the distance between the heat sink 43 and the terminal 42 can be shortened to the maximum extent, the heat dissipation capability of the heat sink 43 is fully utilized, and the terminal 42 is cooled down quickly.
The power adapter 40 and the terminal 42 may perform information interaction through a communication interface (for example, a line 421 where a D + pin on a charging interface of the terminal 42 is located as shown in fig. 4B), that is, the heat sink 43 performs relay; of course, the power adapter 40 and the terminal 42 can also exchange information through wireless communication. When the power adapter 40 charges the terminal 42, the output current of the power adapter 40 flows into the terminal 42 after passing through the heat sink, and charges the battery pack on the terminal 42.
S407, determining a third charging power based on the second charging power and the other current state information;
it can be understood that, when the charging parameters set by the user are not included in the current state information, that is, the user does not set the current charging parameters of the terminal, through step S407 and step S408, on the premise of ensuring charging safety, automatic adjustment of the current charging power of the terminal is achieved; thus, when the terminal is in the charging state, if the user does not use the terminal, the charging speed can be increased and the charging duration can be shortened through the steps S407 and S408; when the terminal is in a charging state, if the user is using the terminal, through the steps S407 and S408, the influence of the charging speed and the heating degree of the terminal on the user using the terminal can be equalized, so that the charging experience of the user is improved.
S408, determining the target charging power based on the second charging power and the third charging power;
it can be understood that, if the current state information does not include the charging parameter set by the user, the target charging power may be determined based on the other current state information, so as to implement automatic adjustment of the charging power, equalize the influence of the charging speed and the heating degree on the user using the terminal, and improve the charging experience of the user.
It should be noted that steps S406 to S408 are another implementation example of "determining the target charging power based on the current state information".
In other embodiments, if the charging parameter set by the user is not included in the current state information, the second charging power may also be directly determined as the target charging power, so as to improve the charging efficiency of the battery pack and reduce the charging duration.
And S409, charging the battery assembly of the terminal by using the target charging power.
The embodiment of the present application provides another charging method, including steps S501 to S508:
s501, acquiring current state information of the terminal after detecting that the terminal is electrically connected with a power adapter; the current state information comprises the current battery temperature, the current battery electric quantity and the current memory expenditure of the terminal;
here, it should be noted that, since the charging parameter is not set by the user, when the current state information of the terminal is acquired, the charging parameter set by the user cannot be acquired, that is, the charging parameter set by the user is not present in the current state information.
S502, determining a second charging power based on the battery temperature and the battery electric quantity, wherein the second charging power is the maximum safe charging power which can be currently accepted by the battery assembly;
s503, determining whether the terminal is electrically connected with the power adapter through a heat dissipation device; if yes, go to step S504; otherwise, go to step S507;
for example, the terminal may determine whether to establish an electrical connection with the power adapter through the heat sink by analyzing a communication signal sent by a device directly connected to the terminal.
It is understood that the determined second charging power (i.e., the maximum safe charging power) may obtain a greater second charging power when the terminal is connected with the heat sink than when the terminal is not connected with the heat sink. Therefore, when the terminal is connected with the heat sink, if the battery pack is charged using the second charging power, the charging can be completed more quickly.
S504, obtaining heat dissipation parameters of the heat dissipation device, wherein the heat dissipation parameters are used for representing the heat dissipation capacity of the heat dissipation device, and then entering the step S505;
for example, the heat dissipation parameter may be a rated power, a heat dissipation manner, and the like of the heat dissipation device, and the larger the rated power is, the stronger the heat dissipation capability is; the heat dissipation method may be, for example, fan heat dissipation, or cooling heat dissipation, and the cooling heat dissipation capability is relatively strong. In other embodiments, the body temperature or the battery temperature of the terminal may be periodically obtained, and then the falling speed of the body temperature or the battery temperature may be calculated, and the falling speed of the body temperature or the battery temperature may be determined as the heat dissipation parameter.
S505, determining the third charging power based on the second charging power, the heat dissipation parameter and the memory overhead, and then entering step S507;
it can be understood that when the charging parameters set by the user are not included in the current state information, in an application scenario where the user uses the terminal while charging, if the battery pack is directly charged with the second charging power (i.e., the current maximum safe charging power of the battery pack), the battery may be continuously heated and heated, which may bring a bad charging experience to the user. Therefore, in the embodiment of the application, the target charging power is determined by combining the heat dissipation parameters and/or the memory overhead, so that the influence of the charging speed and the heating degree of the terminal on the terminal using of a user is effectively balanced, and the charging experience of the user is improved.
For example, the influence degrees of the second charging power, the heat dissipation parameter, and the memory overhead on the target charging power may be determined, and the third charging power may be determined based on the influence degree of each current state.
S506, determining the third charging power based on the second charging power and the memory overhead;
s507, determining the target charging power based on the second charging power and the third charging power; for example, comparing the magnitude relationship between the second charging power and the third charging power, and if the third charging power is greater than or equal to the second charging power, determining the second charging power as a target charging power; determining the third charging power as a target charging power if the third charging power is less than the second charging power; therefore, the target charging power is always smaller than or equal to the current maximum safe charging power of the battery pack, and the charging safety is ensured.
It should be noted that steps S502 to S507 are an example of implementation of "determining the third charging power".
And S508, charging the battery assembly of the terminal by using the target charging power.
In other embodiments, for step S505, determining the third charging power based on the second charging power, the heat dissipation parameter and the memory overhead may be implemented by steps S5051 to S5052 as follows:
s5051, determining a first power increment corresponding to the memory overhead from a preset first power increment mapping table;
it can be understood that the larger the current memory overhead of the terminal is, the more energy is consumed by the load, and the more serious the heating phenomenon is. Therefore, when setting the first power increment map, the first power increment is usually set to a negative value. For example, as shown in table 2, when the memory overhead is less than 1GB, the corresponding first power increment is 0; when the memory overhead belongs to [1.0GB, 1.5GB), the corresponding first power increment is-5W; when the memory overhead is 1.5GB, 2.0GB), the corresponding first power increment is-10W.
TABLE 2
| Memory overhead | First power increment |
| [0，1GB) | 0 |
| [1.0GB，1.5GB) | -5W |
| [1.5GB，2.0GB) | -10W |
| …… | …… |
S5052, determining a second power increment corresponding to the heat dissipation parameter from a preset second power increment mapping table;
it is understood that the stronger the heat dissipating capability of the heat dissipating device, the faster the body temperature or the battery temperature of the terminal drops, and thus, the second power increment is generally set to a positive value when the second power increment map is set. For example, when a fan is disposed in the heat dissipation device, the corresponding heat dissipation parameter is represented by the rotation speed of the fan, and as shown in table 3, when the rotation speed of the fan is less than 2000 rpm, the corresponding second power increment is 5W, and when the rotation speed of the fan is [2000 rpm, 3000 rpm ], the corresponding second power increment is 10W; when the rotating speed of the fan is [3000 r/min, 4000 r/min ], the corresponding second power increment is 15W.
TABLE 3
| Rotating speed of fan | First power increment |
| [0, 2000 rpm) | 5W |
| [2000 rpm, 3000 rpm) | 10W |
| [3000 rpm, 4000 rpm) | 15W |
| …… | …… |
S5053, accumulating the second charging power, the first power increment and the second power increment to obtain the third charging power.
In other embodiments, if the connection mode between the terminal and the power adapter is such that the terminal establishes electrical connection with the power adapter through a power line, the third charging power is determined based on the second charging power and the memory overhead. For example, the second charging power and the first power increment are accumulated to obtain the third charging power.
Generally speaking, when a mobile phone is charged with high power quickly, the larger the power is, the faster the mobile phone is charged with high heat, but the more serious the heat is, and the heat generation phenomenon caused during charging can bring some bad experiences to a user.
For example, the user is in urgent need to fully charge the mobile phone at this time, and can tolerate more serious heating, that is, quick charging is the main requirement, heating is gradually changed into the secondary requirement, the user can select the maximum power to charge at this time, and the mobile phone can quickly charge at the maximum power within the safety range.
For another example, when charging a mobile phone, a user is playing a game, and at this time, the heat of the mobile phone cannot be tolerated, the heat generation is gradually changed into a main requirement, the charging speed is changed into a secondary requirement, the user can select low power to charge at this time, and the mobile phone can perform quick charging at the power closest to the power selected by the user in a safe range.
In the conventional high-power charging scheme, the charging power is controlled at the background of the mobile phone, and a user cannot control the charging power by himself. In the embodiment of the application, the user can set different charging powers in different application scenes to balance the influence of the charging speed and the heating degree on the mobile phone, so that better use experience is brought.
For example, a preset charging power setting interface is displayed on the mobile phone, and the button (i.e., charging power gear) selected by the user may be a specific numerical value, such as 20W, 30W, 40W, 50W, 60W, 70W, 80W, 90W, 100W, or may be an unspecified numerical value, such as high power, medium power, and low power.
The display mode of the button selected by the user can be selected by a pop-up box, can also be hidden in a notification bar for the user to select, and can also be selected from sub-options in a 'setting' APP of the mobile phone.
Assume that the user selectable charging power P _ user is 20W, 30W, 40W, 50W, 60W, 70W, 80W, 90W, 100W; the charging power P _ set which can be set by the background is 20W, 30W, 40W, 50W, 60W, 70W, 80W, 90W and 100W. When a User inserts the mobile phone into a power adapter for charging, a button for selecting charging power appears on a User Interface (UI) of the mobile phone for the User to select.
Under the conditions of different battery temperatures and different battery electric quantities, the current maximum safe charging power calculated by the background is Pmax _ set1, the charging power selected by the user on the mobile phone interface is P _ user1,
if P _ user1> is Pmax _ set1, the mobile phone is charged with the current maximum safe charging power Pmax _ set 1;
if the P _ user1 is less than Pmax _ set1, the mobile phone is charged by the charging power P _ user1 selected by the current user;
if the user does not select, the mobile phone is charged with the current maximum safe charging power Pmax _ set 1.
In addition, it should be noted that, regarding the implementation of high-power charging, the following modes can be referred to:
1. under the condition of not considering the heat of the mobile phone, the heat dissipation can be directly realized by increasing the output power of the power adapter. The charging architecture can use the existing fast charging architecture (low voltage and large current) or other charging architectures (high voltage and small current).
2. When the heat of the mobile phone is considered, that is, the heat of the mobile phone needs to be controlled, an additional heat dissipation device (for example, a fan, a cooling heat dissipation mode, or the like) may be added to dissipate the heat of the mobile phone being charged. The connection relationship between the handset, the power adapter and the heat sink is shown in fig. 4B.
