[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The control method of the charging circuit provided in the embodiment of the present invention can be applied as follows: Figure 1Specifically, the control method of the charging circuit is applied in a charger, which includes: Figure 1 The charging circuit 1 and the controller 2 shown are connected to the charging circuit 1 and are used to obtain charging information of the charging circuit 1 when it is working, and control the operation of the charging circuit 1 according to the charging information.

[0020] In one embodiment, if Figure 2 As shown, a control method for a charging circuit is provided, and the method is applied in Figure 1 The controller 2 in the example is used as an example to illustrate the process, which includes the following steps: S201: Acquire first charging information of a charging circuit; S202: determining a target charging habit based on the first charging information, and obtaining a charging habit determination result; S203: If the charging habit determination result is that the target charging habit exists, controlling the charging circuit to enter the first target working mode and obtaining second charging information of the charging circuit; S204: If the second charging information satisfies the termination condition corresponding to the first target operating mode, control the charging circuit to exit the first target operating mode.

[0021] The target charging habit refers to a charging pattern exhibited by the user during the N charging processes, including a sleeping charging habit or an office charging habit with a regular charging scenario.

[0022] Among them, the first target working mode is a pre-set working mode corresponding to the target charging habit. The working mode specifies the charging protocol, charging power and charging state adopted by the charger, and may include a fast charging working mode and a fast charging working mode. Specifically, the slow charging working mode may include that the controller controls the charging circuit 1 to communicate with the device to be charged according to the preset slow charging protocol (such as QC1.0) in accordance with the first preset working strategy, so that the charging circuit 1 works in a slow charging state or a trickle charging state or a full charging state according to the charging requirements; the fast charging working mode may include that the controller communicates with the device to be charged according to the preset fast charging protocol (such as PD2.0) in accordance with the second preset working strategy, so that the charging circuit 1 works in a fast charging state or a trickle charging state or a full charging state according to the charging requirements. When the charging circuit 1 is powered on for the first time, the controller 2 sets the charging circuit 1 to the fast charging working mode for charging by default.

[0023] As an example, in step S201, before the current charging process starts, the controller 2 obtains the first charging information of the charging circuit 1 in the historical N (N≥10) charging processes. The first charging information is used to determine whether the charging circuit 1 has a target charging habit in the historical N charging processes. For example, the first charging information can be the full charging time of each of the historical N charging processes. Among them, a charging process starts with the device to be charged 4 connecting to the charging circuit 1 for charging and ends with the device to be charged 4 disconnecting the charging circuit 1 to stop charging.

[0024] As an example, in step S202, before the current charging process starts, the controller 2 performs a target charging habit judgment on the charging circuit 1 based on the first charging information of the charging circuit 1 in the historical N charging processes, and obtains a charging habit judgment result. For example, if in the historical N charging processes, the full charging time of each time is greater than a preset time, such as 5 hours, then it is determined that the charging circuit 1 has a target charging habit in the historical N charging processes.

[0025] As an example, in step S203, if the charging habit judgment result is that there is a target charging habit, it means that the user is accustomed to using the charging circuit 1 to charge the charging device 4 in a certain scenario (such as a sleeping scenario / working scenario). At this time, the controller 2 controls the charging circuit 1 to work in the first target working mode at the beginning of this charging process, such as a slow charging working mode, and locks the maximum charging power to a smaller preset charging power for charging, so as to extend the charging time and reduce damage to the battery. At the same time, when the charging circuit 1 works in the first target working mode, the controller 2 also continuously obtains the second charging information of the charging circuit 1, and the second charging information is used to detect whether the charging circuit 1 meets the termination condition corresponding to the first target working mode. When the controller 2 detects that the charging circuit 1 meets the termination condition corresponding to the first target working mode according to the second charging information, it proves that the charging circuit 1 has broken the target charging habit and needs to exit the first target working mode.

[0026] As an example, in step S204, when the controller 2 detects that the charging circuit 1 meets the termination condition corresponding to the first target working mode according to the second charging information and needs to exit the first target working mode, the controller 2 controls the charging circuit 1 to exit the first target working mode, so that during the entire charging process, the charging circuit 1 operates in a reasonable working mode and can be charged with a reasonable charging power. Furthermore, after controlling the charging circuit 1 to exit the first target working mode, the controller 2 can continue to control the charging circuit 1 to enter the second target working mode. For example, when the first target working mode is the slow charging working mode, the controller 2 can continue to control the charging circuit 1 to enter the fast charging working mode when controlling the charging circuit 1 to exit the slow charging working mode, so that the charging circuit 1 charges the charging device according to the maximum allowed charging power to prevent affecting the charging efficiency.

[0027] In this example, the controller 2 can determine whether there is a target charging habit by detecting the first charging information, and when the target charging habit exists, the charging circuit 1 operates in the first target working mode. The controller 2 can also detect the second charging information of the charging circuit 1 in the first target working mode to determine whether the target charging habit is broken, and exit the first target working mode in time, so that it can charge at a reasonable charging power during the charging process.

[0028] In one embodiment, step S202, i.e., performing target charging habit determination based on the first charging information and obtaining a charging habit determination result, includes: S301: Counting a first target ratio of the target charging times corresponding to the target charging process to the total charging times within a historical detection period, wherein the target charging process is a charging process whose first charging information satisfies a target charging condition; S302: If the first target ratio is greater than the first ratio threshold, determining that the charging habit determination result is that the target charging habit exists; S303: If the first target ratio is not greater than the first ratio threshold, determining that the charging habit determination result is that the target charging habit does not exist.

[0029] Among them, the historical detection cycle is a pre-set detection cycle for determining whether there is a target charging habit in the historical charging process. The historical detection cycle may include a preset time period, such as the past 240 hours, at which time the total number of charging times is the sum of the number of charging times in the past 24 hours. The historical detection cycle may also include N consecutive charging processes in history (N≥10), at which time the total number of charging times is N. The target charging process is the charging process in which the first charging information meets the target charging condition. The first ratio threshold is a threshold used to determine whether there are more target charging processes within the historical detection cycle.

[0030] As an example, in step S301, the controller 2 records the charging process in which the first charging information meets the target charging condition within the historical detection cycle as the target charging process. After a historical detection cycle ends and before the current charging process starts, the controller 2 counts the target charging times corresponding to the target charging process within the entire historical detection cycle, and then calculates the first target ratio of the target charging times to the total charging times, and compares the first target ratio with the first ratio threshold to determine whether there are more target charging processes within the historical detection cycle, so as to determine whether there is a target charging habit.

[0031] As an example, in step S302 , when the first target ratio is greater than the first ratio threshold, the controller 2 determines that there are more target charging processes in the historical detection period, and further determines that the charging circuit 1 has a target charging habit.

[0032] As an example, in step S303, when the first target ratio is not greater than the first ratio threshold, the controller 2 determines that the target charging process is small in the historical detection period and there is no target charging habit.

[0033] In one embodiment, the target charging habit includes a sleep charging habit; the target charging process includes a sleep charging process; the target charging times includes a sleep charging times; and the first target working mode includes a slow charging working mode.

[0034] As an example, when the target charging habit is a sleep charging habit, the controller 2 records the charging process in which the first charging information meets the target charging condition within the historical detection cycle as a sleep charging process. After a historical detection cycle ends and before the current charging process begins, the controller 2 counts the number of sleep charging times corresponding to the sleep charging process within the entire historical detection cycle, and then calculates the first target ratio of the number of sleep charging times to the total number of charging times, and compares the first target ratio with the first ratio threshold. When the first target ratio is greater than the first ratio threshold, it is determined that there are more sleep charging processes within the historical detection cycle, and then it is determined that the charging circuit 1 has a sleep charging habit, otherwise, it does not exist. When the charging circuit 1 has a sleep charging habit, the controller 2 controls the charging circuit 1 to operate in a slow charging mode, so that the charging power of the charging circuit 1 adapts to the user's charging habits, and charges at a reasonable charging power to prevent fast charging when unnecessary, which affects the battery life.

[0035] In this embodiment, the first charging information includes the maximum charging power of the charging circuit 1 and the duration of the full-charged state; the target charging condition includes that the maximum charging power of the charging circuit 1 is greater than the first preset power, and the duration of the full-charged state is greater than the first preset time threshold, or the maximum charging power of the charging circuit 1 is not greater than the first preset power, and the duration of the full-charged state is greater than the second preset time threshold.

[0036] The maximum charging power of the charging circuit 1 is the peak charging power of the charging circuit 1 in a charging process. The duration of the fully charged state is the total duration of the state in which the battery of the device to be charged 4 is fully charged but the charging connection is not disconnected in a charging process of the charging circuit 1.

[0037] As an example, the first charging information includes the maximum charging power of the charging circuit 1 and the duration of the full-charge state in each charging process within the historical detection cycle. When the target charging habit is the sleep charging habit, the target charging condition for determining whether a charging process is a sleep charging process specifically includes that in a charging process, the maximum charging power of the charging circuit 1 is greater than the first preset power, and the duration of the full-charge state is greater than the first preset time threshold, that is, in a certain charging process, if the charging power peak value of the charging circuit 1 in the entire charging process is greater than the first preset power, and the duration of the full-charge state is greater than the first preset time threshold, it indicates that the charging process is a sleep charging process, otherwise it is not a sleep charging process. Alternatively, in a charging process, the maximum charging power of the charging circuit 1 is not greater than the first preset power, and the duration of the full-charge state is greater than the second preset time threshold, that is, in a certain charging process, if the charging power peak value of the charging circuit 1 in the entire charging process is not greater than the first preset power, and the duration of the full-charge state is greater than the second preset time threshold, it indicates that the charging process is also a sleep charging process, otherwise it is not a sleep charging process. Among them, the first preset power is a power threshold used to determine whether the charging circuit 1 is currently in a slow charging working mode or a fast charging working mode during the charging process. For example, the first preset power can be 20W. When the maximum charging power is greater than 20W, the charging circuit 1 works in the fast charging working mode during the charging process. When the maximum charging power is not greater than 20W, the charging circuit 1 works in the slow charging working mode during the charging process. Since the time required to fully charge the battery is different under the same battery remaining power state when the same device to be charged is charged in the slow charging working mode and the fast charging working mode, it is necessary to set the first preset time threshold and the second preset time threshold to distinguish and judge the fast charging working mode and the first target working mode. The first preset time threshold is the time threshold corresponding to the fast charging working mode for determining whether the charging process is a sleep charging process, and the second preset time threshold is the time threshold corresponding to the slow charging working mode for determining whether the charging process is a sleep charging process. For example, if the charging power peak value of the charging circuit 1 in the entire charging process is greater than the first preset power (20W), and the duration of the full-charged state is greater than the first preset time threshold (5 hours), it indicates that the charging process is a sleep charging process, or, if the charging power peak value of the charging circuit 1 in the entire charging process is not greater than the first preset power (20W), and the duration of the full-charged state is greater than the second preset time threshold (3 hours), it indicates that the charging process is also a sleep charging process.

[0038] In one embodiment, step S301, i.e., when the charging circuit 1 is in the fast charging working mode, obtaining first charging information of the charging circuit 1, includes: S401: Obtain output power of a charging circuit, and based on the output power, obtain a maximum charging power of the charging circuit; S402: If the output power of the charging circuit is less than the second preset power, determine that the charging circuit is in a fully charged state, and obtain a duration of the charging circuit being in the fully charged state.

[0039] As an example, in step S401, in each charging process within the historical detection cycle, the controller obtains the output power of the charging circuit 1, and uses the peak value of the output power of the charging circuit 1 in a charging process as the maximum charging power of the charging process.

[0040] The second preset power is a power threshold for judging whether the battery of the device to be charged 4 is fully charged during the charging process, for example, 0.3 W. When the battery of the device to be charged 4 is fully charged, the charging circuit 1 still needs to continue to provide a small current to maintain the power supply state of the device to be charged 4 to ensure that the battery power of the device to be charged 4 will not decrease due to self-discharge. Therefore, by judging whether the output power is less than the second power threshold, it can be judged whether the charging circuit 1 is in a fully charged state.

[0041] As an example, in step S402, in each charging process within the historical detection cycle, the controller obtains the output power of the charging circuit 1. If in a certain charging process, the controller 2 detects that the output power of the charging circuit 1 is less than the second preset power, it can be determined that in this charging process, the battery of the charged device 4 has been fully charged, but the charging connection with the charging circuit 1 has not been disconnected, that is, the charging circuit 1 has entered the full charging state in this charging process. At this time, the controller 2 starts to calculate the duration of the full charging state until the entire charging process is completed, so as to measure the duration of the charging circuit 1 in the full charging state in this charging process.

[0042] In one embodiment, the second charging information includes a current change rate in a current sampling period; and the termination condition corresponding to the first target operating mode includes that the current change rate is greater than a first preset change rate.

[0043] As an example, when there is a sleep charging habit, the controller 2 controls the charging circuit 1 to work in the slow charging mode at the beginning of this charging process. During the charging process, the controller 2 continues to obtain the current output current of the charging circuit 1 according to the preset sampling frequency, and calculates the current change rate of the current output current within a sampling cycle based on the preset sampling cycle. Since the charging current output by the charging circuit 1 to the device to be charged 4 will change when the device to be charged 4 is used, the controller 2 can indirectly determine whether the device to be charged 4 is used by calculating the current change rate of the current output current within a sampling cycle, and judging whether the current change rate is greater than the first preset change rate, and then judge whether the sleep charging habit is broken. Therefore, when the current change rate is greater than the first preset change rate, it proves that the device to be charged 4 is in use, and it is necessary to exit the slow charging mode in time to prevent affecting the charging efficiency of the charging circuit 1.

[0044] In another embodiment, the second charging information includes a charging mode instruction; the charging information of the target charging circuit 1 in the slow charging mode satisfies the termination condition, including that the charging mode instruction is a slow charging termination instruction.

[0045] The charging mode instruction is an instruction acquired by the controller 2 and is used to set the charging mode of the charging circuit 1 to another working mode, or is an instruction to make the charging circuit 1 exit the first target working mode.

[0046] As another example, the controller 2 can also obtain a charging mode instruction. When the current charging mode of the charging circuit 1 is the first target operating mode, and the obtained charging mode instruction is an instruction for causing the charging circuit 1 to exit the first target operating mode, the controller 2 controls the charging circuit 1 to exit the first target operating mode. Alternatively, when the current charging mode of the charging circuit 1 is the first target operating mode, and the obtained charging mode instruction is a fast charging operating instruction, the controller 2 controls the charging circuit 1 to exit the first target operating mode. For example, when the current charging mode of the charging circuit 1 is a slow charging operating mode, and the obtained charging mode instruction is a slow charging operating mode exit instruction, or a fast charging operating mode instruction, the controller 2 controls the charging circuit 1 to exit the slow charging operating mode.

[0047] In one embodiment, after step S204 , ie, controlling the charging circuit 1 to exit the first target working mode, the method for controlling the charging circuit further includes: controlling the charging circuit 1 to enter the second target working mode.

[0048] As an example, the second target operating mode can be a default preferred operating mode that the controller 2 controls the charging circuit 1 to enter after detecting that the target charging habit is broken, such as a fast charging operating mode. For example, when the sleep charging habit is broken, the controller 2 controls the charging circuit 1 to enter the fast charging operating mode to avoid the situation where the device to be charged 4 charges too slowly and cannot meet the user's charging needs when being used.

[0049] The embodiment of the present invention further provides a controller 2, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the following is achieved: Figure 2-Figure 4 A control method for a charging circuit in a device.

[0050] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0051] An embodiment of the present invention also provides a charger, including a charging circuit 1 and the controller 2 in the above embodiment; one end of the charging circuit 1 is used to connect to a mains power supply 3, and the other end is used to connect to a device to be charged 4; the controller 2 is connected to the charging circuit 1, and is used to obtain charging information and control the operation of the charging circuit 1 according to the charging information.

[0052] As an example, the charger includes a charging circuit 1 and a controller 2 in any of the above examples. One end of the charging circuit 1 is used to connect to a mains power supply 3, and the other end is used to connect to a device to be charged 4. The controller 2 is connected to the charging circuit 1 and is used to obtain first charging information of the charging circuit 1 to make a target charging habit judgment based on the first charging information. If the charging habit judgment result is that the target charging habit exists, the controller 2 controls the charging circuit 1 to enter the first target working mode. After the charging circuit 1 works in the first target working mode, the controller 2 obtains second charging information of the charging circuit 1, judges whether the target charging habit is broken, and exits the first target working mode in time.

[0053] In this example, the controller 2 can determine whether there is a target charging habit, such as a sleep charging habit, by detecting the first charging information, and when the target charging habit exists, the charging circuit 1 operates in the first target working mode. The controller 2 can also detect the second charging information of the charging circuit 1 in the first target working mode to determine whether the target charging habit is broken, and exit the first target working mode in time, so that it can charge at a reasonable charging power during the charging process.

[0054] In one embodiment, the charger further includes a voice recognition module 5 ; the voice recognition module 5 is connected to the controller 2 , and is used to send a charging mode instruction to the controller 2 according to the received audio information.

[0055] As an example, the charger also includes a voice recognition module 5, which is connected to the controller 2 and is used to recognize the received audio information to send a charging mode instruction to the controller 2, so that the controller 2 controls the charging circuit 1 to work in the second target working mode, or exit the first target working mode. By setting the voice recognition module 5, the voice instruction issued by the user for adjusting the working mode of the charging circuit 1 can be recognized, and the working mode of the charging circuit 1 can be voice-controlled, so that the charging circuit 1 switches the working mode according to the user's needs, further adapting to the user's needs.
