Fig. 1 is a schematic view of an application environment of a charging control method in an embodiment. As shown in fig. 1, the application environment includes an electronic device 10, and a charging device 20 that charges the electronic device 10. The electronic device 10 may be a headset, a mobile phone, a tablet computer, a PDA (Personal Digital Assistant ), a POS (Point of Sales), a car computer, a wearable device (e.g., a bracelet, a smart glasses), etc. The charging device 20 may be a charging cartridge, a charging stand, a charger, etc.
Fig. 2 is a flow chart of a charge control method in one embodiment. The charge control method in this embodiment is described taking the electronic device (e.g. earphone) 10 in fig. 1 as an example, and as shown in fig. 2, the charge control method includes steps 202 to 206.
Step 202, detecting a charging parameter of the electronic device during charging.
In one embodiment, the earphone may include a charging interface, a detection module, and a charging circuit. The charging interface is used for being connected with the charging box so as to receive charging parameters and communication data sent by the charging box. The charging circuit is connected with the charging interface and is used for receiving the charging parameters and processing the charging parameters to output the charging parameters suitable for charging the earphone. The detection module is connected with the charging interface and is used for detecting the charging parameters sent by the charging box. Wherein the charging parameter may include at least one of a charging current, a charging voltage, and a charging temperature. If the charging parameter includes charging current and charging voltage, the corresponding detection module can adopt a voltage dividing circuit formed by discrete elements such as resistors and/or capacitors to realize detection of the charging parameter. If the charging parameter includes a charging temperature, the corresponding detection module can adopt a temperature detection module composed of temperature sensitive devices and the like to realize detection of the charging parameter.
It should be noted that, in the embodiment of the present application, the specific composition of the detection module is not further limited, and is not limited to the above-mentioned examples.
Step 204, detecting whether the electronic device has an abnormality in the charging process according to the charging parameters.
The earphone can judge whether the earphone is abnormal in the charging process according to the detected charging parameters. Whether the abnormality exists or not can be judged by judging whether the charging parameters detected by the earphone are out of a preset range corresponding to the charging parameters or not. For example, if the charging voltage and/or the charging current received by the earphone is smaller than the charging voltage and/or the charging current sent by the charging box, the charging process of the earphone is considered to be abnormal; for example, if the temperature signal is higher than the preset temperature threshold, the charging process of the earphone is considered to be abnormal. Whether the earphone is abnormal or not can also be judged by whether the earphone receives the charging parameters or the communication data sent by the charging box or not, for example, when the charging interface of the earphone is separated from the charging port of the charging box, that is, the earphone is physically disconnected from the charging box, the charging process of the earphone is determined to be abnormal or the like.
In step 206, if there is an abnormality, a shutdown operation is performed.
If the charging process of the earphone is abnormal, executing a shutdown operation to control the earphone to shutdown. The power-off operation is understood to be that other circuit modules of the earphone are controlled to be powered off to stop working, for example, the charging circuit can be controlled to stop charging the battery unit, and after the charging circuit stops charging the battery unit, the control module of the earphone is controlled to be in a power-off state, that is, a power-off state supporting soft reset by a low-power consumption wake-up function.
According to the charging control method, the charging parameters of the electronic equipment in the charging process can be detected, whether the electronic equipment is abnormal in the charging process is detected according to the charging parameters, and if the electronic equipment is abnormal, the electronic equipment is controlled to be powered off. Based on the method, once the charging process of the electronic equipment is abnormal, the shutdown operation can be directly executed without receiving a shutdown instruction sent by the charging box, and the electronic equipment controls each circuit module inside to be in a shutdown state, so that the electronic equipment is in the shutdown state, the situation that the electronic equipment cannot be charged but is always in standby due to abnormal conditions such as poor contact and abnormal charging equipment can be avoided, further, the consumption of electric quantity can be avoided, the electric quantity of the electronic equipment is saved, and the endurance time of the electronic equipment is prolonged.
Fig. 3 is a flowchart of a charging control method according to another embodiment. In one embodiment, the charge control method includes steps 302-306.
Step 302, detecting a charging parameter of the electronic device during charging.
Step 304, detecting whether the electronic device has an abnormality in the charging process according to the charging parameters.
And 306, if the abnormality exists, controlling a charging circuit of the electronic equipment to stop charging the battery unit of the electronic equipment, and detecting whether the electronic equipment receives a wake-up instruction sent by the charging box within a preset time period.
When the earphone is abnormal in the charging process, a charging passage between the charging circuit and the charging interface can be cut off so as to control the charging circuit to stop charging the battery unit of the earphone; the charging management chip in the charging circuit can be controlled to be in a shutdown state so as to control the charging circuit to stop charging the battery unit of the earphone and the like.
When the charging circuit stops charging the battery unit, the earphone can further detect whether a wake-up instruction sent by the charging box is received within a preset time period. The wake-up instruction is used for waking up the charging circuit so that the charging circuit can continue to charge the battery unit. In particular, the headset may further comprise a communication module connected to the charging interface, the communication module being operable to transmit communication data. Based on the communication module, data transmission functions such as data transmission and data receiving between the earphone and the charging box can be realized. For example, when the charging circuit of the headset stops charging the battery unit, the headset may control the communication module to implement data transmission with the charging cartridge so that the headset is in a communication state. When the earphone is in a communication state, the earphone can monitor whether the communication data comprise a wake-up instruction in real time in a preset time period. For example, the wake-up instruction may be transmitted in the form of a preset code string.
Specifically, the preset time period may be set to be in the millisecond level, the second level, for example, 0 millisecond, 1 second, etc., and in the embodiment of the present application, the specific duration of the preset time period is not further limited, and is not limited to the above illustration.
Step 308, if the wake-up instruction is not received, executing a shutdown operation.
When the charging circuit stops charging the battery unit and the communication module does not receive the wake-up instruction sent by the charging box within a preset time period, the communication module indicates that the abnormality of the charging process is true, that is, the abnormality is valid, and at the moment, the control module of the earphone can be controlled to be in a shutdown state.
According to the charging control method, when the charging circuit of the earphone stops charging the battery unit, whether the wake-up instruction sent by the charging box is received in a preset time period can be further detected, and the earphone is controlled to be powered off under the condition that the wake-up instruction is not received, and by setting the preset time period, the earphone can be given a buffer time period, so that the earphone is prevented from being directly controlled to be powered off due to short-time charging interruption, and the charging efficiency and the charging flexibility can be improved.
In one embodiment, the charging control method further includes step 310, if a wake-up instruction is received, controlling the charging circuit to continue charging the battery unit of the electronic device.
When the charging circuit stops charging the battery unit and the communication module of the earphone receives a wake-up instruction sent by the charging box in a preset time period, the earphone can control the charging circuit to continuously charge the battery unit of the earphone according to the wake-up instruction. Specifically, if the current charging path of the charging circuit is disconnected, the charging path between the charging circuit and the charging interface can be conducted at this time to control the charging circuit to continue charging the battery unit of the earphone; if the charging management chip of the charging circuit is in a shutdown state at present, at this time, the charging management chip can be awakened to be in a working state so as to control the charging circuit to continuously charge the battery unit of the earphone.
According to the charging control method in the embodiment, even when the charging circuit stops charging the battery unit of the earphone, the charging circuit can be controlled to continuously charge the battery unit based on the wake-up instruction sent by the charging box, so that the flexibility of charging the earphone can be provided, and the condition that the earphone is powered off due to abnormal misjudgment in the charging process is avoided.
In one embodiment, detecting whether the electronic device has an abnormality in the charging process according to the charging parameter specifically includes determining that the charging process has an abnormality if the charging parameter is outside a preset range corresponding to the charging parameter. Specifically, the charging parameters include at least one of a charging voltage, a charging current, and a charging temperature. If the charging parameter includes only one signal, such as a charging voltage, a charging current, or a charging temperature, the preset ranges corresponding to the different charging parameters are different. If the value of the charging parameter is within the corresponding preset range, the charging process of the earphone can be determined to be normal (i.e. no abnormality exists), and if the value of the charging parameter is outside the preset range, the charging process of the earphone can be determined to be abnormal.
In one embodiment, the charging parameter is a charging voltage, and if the charging voltage is lower than a preset voltage threshold, it is determined that an abnormality exists in the charging process. The preset voltage threshold may be understood as a standard charging voltage output by the charging box. For example, the preset voltage threshold is 5V, and if the charging voltage detected by the detection module of the earphone is less than 5V, it is determined that an abnormality exists in the charging process. In addition, if the detection module of the earphone does not detect the charging voltage, the charging voltage may be understood as 0V.
Optionally, when the charging parameter is charging current, it may also be detected whether the charging current is within a preset current range for a year, if so, the charging process of the earphone is normal; otherwise, the charging process of the earphone is abnormal.
In one embodiment, the charging parameter is a temperature signal, and if the temperature signal is within a preset temperature range, the charging process of the earphone is normal; otherwise, the charging process of the earphone is abnormal. The preset temperature range may be set, for example, between-40 degrees celsius. If the value of the temperature signal is 50 ℃, the charging process of the earphone is determined to be abnormal.
It should be noted that, when the charging parameter includes at least two signals, the boundary value of each preset range may be adjusted according to the correlation between the respective signals.
As shown in fig. 4, in one embodiment, the charging control method further includes:
step 402, detecting a charging parameter of the electronic device in a charging process;
step 404, acquiring the accumulated charging frequency of the electronic device.
The earphone is arranged in the charging box, when the earphone receives the charging parameters of the charging box to charge, the earphone can count the charging frequency (or called the charging frequency) of the battery unit, and can accumulate the charging frequency and store the charging frequency.
In one embodiment, the earphone also determines whether the current charging process meets the requirement of the accumulated count in the process of performing the accumulated count on the charging frequency of the battery, if the current charging process meets the requirement of the accumulated count, the accumulated count is performed, and if the current charging process does not meet the requirement of the accumulated count, the charging frequency is not counted. By way of example, the cumulative count requirement may be understood as a complete charging process.
Step 406, constructing a preset range corresponding to the charging parameter according to the charging parameter and the charging frequency.
In one embodiment, the earphone may acquire the charging parameters under the preset charging conditions during the charging process. Wherein, the preset condition can be preconfigured in the earphone. The preset condition may be constant voltage continuous charging from a preset characteristic point for a preset period of time, and the corresponding charging parameter is a charging temperature or a charging current. The preset condition may be that the first preset current is charged from constant voltage to the second preset current, and the charging parameter corresponding to the preset condition is the charging temperature.
The preset range corresponds to the charging parameters, that is, each charging parameter is correspondingly configured with a preset range. When the preset charging conditions are different, the preset ranges of the charging parameters for the same charging frequency may be the same or different. That is, the mapping relationship between the charging frequency, the preset charging condition, the charging parameter, and the preset range may be correspondingly constructed. Wherein, the preset charging condition and the charging frequency jointly correspond to a preset range. When the relationship between the four is established, a preset range=f (preset charging condition, charging frequency, charging parameter). The relationship may be fixed by means of a mapping table. The relationship may be provided by the system, recommended, or customized by the user.
The electronic equipment can acquire the charging frequency of the current charging process and the charging parameter of the current charging process, and construct a preset range corresponding to the charging parameter according to the charging frequency and the charging parameter. The charging frequencies are different, and the detection standards for detecting the charging parameters are different. For example, when the charging frequency is 100 times and 200 times, respectively, the result of detecting whether the battery cell is abnormal correspondingly may be different for the same charging parameter due to the different charging frequencies.
In step 408, if the charging parameter is outside the preset range of the corresponding charging parameter, it is determined that the charging process is abnormal.
Step 410, a shutdown operation is performed.
In one embodiment, if the preset charging condition is a preset duration of continuous charging from the preset feature point, the corresponding charging parameter is temperature information. The earphone can determine the preset charging condition and the preset range of the charging parameters corresponding to the charging frequency based on the mapping relation. For example, a temperature value corresponding to a charging voltage (constant voltage) of 5V for a preset period of 15 minutes from the start of 1A charging current may be used as the charging parameter. Based on the mapping relation, the standard parameter range of the temperature information corresponding to the charging frequency of 100 times is 27.5-28.3 ℃. If the temperature information collected under the preset charging condition is within 27.5-28.3 ℃, the charging process is normal, and if the temperature information collected is not within 27.5-28.3 ℃, for example, 29 ℃, the charging process is abnormal.
In this embodiment, the charging parameters may be detected based on the charging frequency, so as to determine whether there is an abnormality in the charging process, so that the battery aging after frequent charging of the battery many times may be avoided, the internal resistance of the battery increases, the reversible capacity decreases, and the occurrence of erroneous judgment of abnormality detection is caused, so that the accuracy of abnormality detection may be improved.
As shown in fig. 5, in one embodiment, the charge control method includes steps 502 to 508.
Step 502, detecting a charging parameter of an electronic device during a charging process.
Step 504, detecting whether the electronic device has an abnormality in the charging process according to the charging parameters.
Step 506, if there is an abnormality, controlling the electronic device to be turned off.
Steps 502 to 506 correspond to steps 2 to 6 in the foregoing embodiments one by one, and are not described here again.
In step 508, if the charging voltage sent by the charging device is received, the charging circuit is controlled to charge the battery unit of the electronic device.
When the earphone is in a power-off state, the detection module of the earphone can still detect the charging voltage received by the earphone charging interface, and the charging voltage can be understood as the charging voltage sent by the charging box and used for charging the earphone. When the detection module of the earphone detects the charging voltage sent by the charging box, the circuit module which can control the earphone to be in the off state is started so as to be in the working state. When the detection module detects the charging voltage sent by the charging box, the control module in the shutdown state can be awakened, and the control module of the earphone controls the charging circuit of the earphone to charge the battery unit.
According to the charging control method in the embodiment, when the charging circuit of the earphone stops charging the battery unit, whether the wake-up instruction sent by the charging box is received in a preset time period can be further detected, and the earphone is controlled to be powered off under the condition that the wake-up instruction is not received, and by setting the preset time period, the earphone can be given a buffer time period, so that the earphone is prevented from being directly controlled to be powered off due to short-time charging interruption, and the charging efficiency and flexibility can be improved. Meanwhile, under the condition that the earphone is in a power-off state, the earphone can be controlled to be powered on, so that the earphone is in a working state, and the charging circuit of the earphone is controlled to charge the battery unit, so that automatic power-on and power-off control of the earphone is realized, meanwhile, automatic switching of the power-on and power-off of the earphone can be realized, the operation flow is simplified, and the experience degree of a user is improved.
It should be understood that, although the steps in the flowcharts of fig. 2-5 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps of fig. 2-5 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor do the order in which the sub-steps or stages are performed necessarily occur sequentially, but may be performed alternately or alternately with at least a portion of the sub-steps or stages of other steps or other steps.

The battery unit 110 may include a single battery cell or may include multiple battery cells connected in series or parallel.

When the control module 150 determines that there is an abnormality in the charging process, the headset may be controlled to be turned off. The control of the earphone to be turned off may be understood as controlling other circuit modules of the earphone to be turned off to stop working, for example, the charging circuit 130 may be controlled to stop charging the battery unit 110, and after the charging circuit 130 stops charging the battery unit 110, the control module 150 is further controlled to be in a turned-off state, where the turned-off state of the control module 150 may be understood as a turned-off state supporting soft reset by a low power wake-up function.

Fig. 7 is a block diagram showing a configuration of a charge control device according to another embodiment. As shown in fig. 7, in one embodiment, the charging control device further includes a communication module 160. The communication module 160 is connected to the charging interface 120 and the control module 150, and is configured to transmit communication data received by the charging interface 120 to the control module 150. The communication module 160 may be directly connected to the first charging contact 121, so that when the third charging contact 211 is in contact conduction with the first charging contact 121, and the fourth charging contact 212 is in contact conduction with the second charging contact 122, data transmission functions such as data transmission and data reception between the control module 150 of the headset and the charging box are implemented based on the communication module 160. By way of example, the communication module 160 may include a data transmission line, which may be a single line, or may include a double line, such as an I2C data bus, or the like. Wherein the communication data comprises at least a wake-up instruction. For example, the wake-up instruction may be transmitted in the form of a preset code string.
The control module 150 is further configured to control the charging circuit 130 to stop charging the battery unit 110 when there is an abnormality, and detect whether the communication module 160 receives a wake-up instruction sent by the charging box within a preset period of time, and if not, control the charging control device to shut down. Specifically, the preset time period may be set to be in the millisecond level, the second level, for example, 100 milliseconds, 200 milliseconds, 1 second, etc., and in the embodiment of the present application, the specific duration of the preset time period is not further limited, and is not limited to the above illustration.
When the charging circuit 130 stops charging the battery unit 110 and the communication module 160 does not receive the wake-up command sent by the charging box within the preset period of time, it indicates that the abnormality of the charging process is true, that is, the abnormality is valid, and at this time, the control module 150 may be controlled to be in a shutdown state.
In one embodiment, the control module 150 is further configured to control the charging circuit 130 to continue charging the battery unit 110 when the communication module 160 receives a wake-up instruction.
In the charging control device of the present embodiment, even when the charging circuit 130 stops charging the battery unit 110 of the headset, the charging circuit 130 can be controlled to continue charging the battery unit 110 based on the wake-up instruction sent by the charging box, so as to provide flexibility of charging the headset, so as to avoid the headset caused by abnormal erroneous judgment in the charging process.
Fig. 8 is a block diagram showing a configuration of a charge control device according to still another embodiment. As shown in fig. 8, in one embodiment, the charge control device further includes a switching circuit 170. The switching circuit 170 is respectively connected to the charging interface 120, the charging circuit 130, and the control module 150, and is configured to receive a control signal sent by the control module 150, and selectively switch on or off a charging path between the charging interface 120 and the charging circuit 130 according to the control signal. Specifically, when the battery unit 110 needs to be charged, the switching circuit 170 may turn on the charging path according to the received control signal, so as to receive the charging signal sent by the charging device 20, so as to charge the earphone; when it is necessary to communicate with the charging device 20, the switching circuit 170 may disconnect the charging path according to the received control signal, and further conduct the communication path between the communication module 160 and the charging interface 120, so as to implement data transmission with the charging device 20, so that the charging control device is switched from the charging state to the communication state.
Specifically, when the control module 150 determines that there is an abnormality, it may send a control signal to control the switching circuit 170 to disconnect the charging path and conduct the communication path between the communication module 160 and the charging interface 120, so that the communication module 160 communicates with the charging device 20, and detects whether the communication module 160 receives a wake-up instruction within a preset period of time, and if not, it controls the charging control device to shut down. If the wake-up command is received within the preset time period, the switching circuit 170 is further controlled to disconnect the communication path and conduct the charging path between the charging circuit 130 and the charging interface 120, so as to continue charging the battery unit 110.
The switching circuit 170 in this embodiment can selectively switch on or off the charging path according to the received control signal, so as to realize automatic switching between the charging state and the communication state of the earphone, so that the charging state and the communication state are mutually independent and do not interfere with each other.
As shown in fig. 8, in one embodiment, the switching circuit 170 includes a first switching transistor Q1 and a second switching transistor Q2. The control electrode of the first switching tube Q1 is connected with the control module 150 and the charging interface 120, and the first electrode of the first switching tube Q1 is grounded; the control electrode of the second switching tube Q2 is connected to the second electrode of the first switching tube Q1, the first electrode of the second switching tube Q2 is connected to the charging interface 120, and the second electrode of the second switching tube is connected to the charging circuit 130.
In one embodiment, the first switching transistor Q1 is a triode, and the second switching transistor Q2 is a MOS transistor (Metal Oxide Semiconductor, metal oxide semiconductor field effect transistor). The base electrode of the triode is the control electrode of the second switching tube Q2, the emitter electrode of the triode is the first electrode of the second switching tube Q2, and the collector electrode of the triode is the second electrode of the second switching tube Q2; the grid electrode of the MOS tube is the control electrode of the first switching tube Q1, the source electrode of the MOS tube is the first electrode of the first switching tube Q1, and the drain electrode of the MOS tube is the second electrode of the first switching tube Q1. That is, the base electrode of the triode is respectively connected with the control module 150 and the charging interface 120, and the emitter electrode of the triode is grounded; the grid of MOS pipe is connected with the collecting electrode of triode, and the source of MOS pipe is connected with interface 120 that charges, and the drain electrode of MOS pipe is connected with charge circuit 130130.
The principle of the switching circuit 170 is illustrated by taking the first switching transistor Q1 as an NPN transistor and the second switching transistor Q2 as a P-type enhancement MOS transistor as an example.
The control signal sent by the control module 150 will act on the NPN transistor. When the control signal is in a high level signal or a high resistance state, the NPN transistor is turned on as long as the charging interface 120 has a voltage signal (e.g., 5V), and when the NPN transistor is turned on, the level of the gate of the MOS transistor is high, so that the MOS transistor can be correspondingly turned on, so that the charging circuit 130 is communicated with the charging interface 120 to turn on the charging path. When the control signal is at a low level, the NPN transistor is turned off, the level of the gate of the MOS transistor becomes a low-high level, so that the MOS transistor is turned off, at this time, the charging path between the charging circuit 130 and the charging interface 120 is disconnected, so that the path circuit communicates with the charging device 20, and meanwhile, the influence of the filter capacitor on the charging path on the communication path can be effectively avoided, so that the communication efficiency and reliability can be improved.
Alternatively, the first switching transistor Q1 and the second switching transistor Q2 may be other types of transistors, for example, various types of semiconductor transistors, field effect transistors, bipolar transistors, insulated gate bipolar transistors, field effect transistors, and the like. It should be noted that, in the embodiment of the present application, the specific types of the first switching tube Q1 and the second switching tube Q2 are not further limited.
In one embodiment, the switching circuit 170 further includes a first resistor R1 and a second resistor R2. The first end of the first resistor R1 is connected with the charging interface 120, and the second end of the first resistor R1 is connected with the control electrode of the first switching tube Q1; the first end of the second resistor R2 is connected with the second end of the first resistor R1, and the second end of the second resistor R2 is connected with the control module 150; the resistance of the first resistor R1 is greater than the resistance of the second resistor R2. That is, the first resistor R1 is disposed on the path between the charging interface 120 and the first switching tube Q1. When the earphone is in the communication state, the charging interface 120 also has a voltage signal (e.g. 3V, 1.8V), and at this time, the level of the control end of the control module 150 is low, and by setting the resistance value of the first resistor R1 to be greater than the resistance value of the second resistor R2, it is possible to prevent the base of the first switching tube Q1 from being divided by the voltage on the charging interface 120 so as to make the first switching tube Q1 and the second switching tube Q2 be turned on.
By providing the first resistor R1 and the second resistor R2 in the switching circuit 170, the resistance value of the first resistor R1 is larger than that of the second resistor R2, so that the earphone can be prevented from being changed to the charging state in the communication state, the communication between the earphone and the charging box 20 is affected, and the stability of the communication state of the earphone is provided.
In one embodiment, the switching circuit 170 further includes a third resistor R3. The first end of the third resistor R3 is connected to the charging interface 120 and the first pole of the second switching tube Q2, and the second end of the third resistor R3 is connected to the second end of the first switching tube Q1 and the control pole of the second switching tube Q2. That is, the third resistor R3 can be understood as a pull-up resistor of the second switching tube Q2 to clamp an uncertain signal at a high level through a resistor, which acts as a current limiting function at the same time.
Referring to fig. 8, in one embodiment, the charging control device includes a charging interface 120, a communication module 160, a charging circuit 130, a switching circuit 170, and a filter capacitor C, where one end of the filter capacitor C is connected to the switching circuit 170 and the charging circuit 130, and the other end of the filter capacitor C is grounded. The filter capacitor C is used for filtering stray waves on the charging path.
In the embodiment of the present application, the filter capacitor C is disposed on the charging path between the charging circuit 130 and the charging interface 120, and when the switching circuit 170 disconnects the charging path to conduct the communication path between the communication module 160 and the charging interface 120, the influence of the filter capacitor C on the charging path on the communication path, that is, the filter capacitor C is isolated from the communication path, so that the influence of the filter capacitor C on the communication path can be avoided, and the data transmission rate of the communication path is increased, so that the communication between the charging control device and the charging device 20 becomes smooth.
In one embodiment, the charging control device further includes: the frequency acquisition module acquires a charging frequency of the battery unit 110 in a current charging process. The control module 150 is connected to the frequency acquisition module, and is configured to construct a preset range corresponding to the charging parameter according to the charging parameter and the charging frequency, and determine that an abnormality exists in the charging process if the charging parameter is outside the preset range corresponding to the charging parameter.
