Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another.
Fig. 1 is a schematic diagram of an application environment of a charging control method in an embodiment. As shown in fig. 1, the application environment may be understood as a charging control system 1, and the charging control system 1 includes a device to be charged 10 and a wireless charging device 20. The device to be charged 10 may be, for example, a mobile phone, a rechargeable wearable device, or other terminal. The wireless charging device 20 may be, for example, a wireless charging cradle.
The device to be charged 10 may include a first charging module 111, the first charging module 111 may include a receiving coil and a controller, and the first charging module 111 is configured to receive an electromagnetic signal of the wireless charging device 20 and convert the electromagnetic signal into a current signal suitable for supplying power to the battery; control over the wireless charging process can also be achieved.
The wireless charging device 20 may include a second charging module 112, a control module 113, and a heat dissipation module 114 disposed inside the housing. The second charging module 112 may be a transmitting coil, configured to wirelessly charge the device to be charged 10; the heat dissipation module 114 may specifically be a heat dissipation fan and a motor connected to the heat dissipation fan, and the control module 113 is connected to the motors of the second charging module 112 and the heat dissipation module 114, and is configured to control the charging parameter of the second charging module 112 and control the on/off and the rotation speed of the motor. The housing of the wireless charging device 20 may be provided with an opening to expose a heat dissipation fan for dissipating heat of the device 10 to be charged.
When the device to be charged 10 is connected to the wireless charging device 20 and is in a wireless charging state, the high-power wireless charging may cause heat generation of the device to be charged 10 and the wireless charging device 20, for example, heat generation of the first charging module 111 and the battery of the device to be charged 10, and heat generation of the second charging module 112 of the wireless charging device 20, so as to increase the overall temperature of the charging control system 1.
Since the heat generation amount of the position of the to-be-charged device 10 corresponding to the transmitting coil is the largest when the to-be-charged device 10 is placed on the wireless charging device 20 for charging, the heat dissipation fan may be disposed near the transmitting coil, so that the heat dissipation fan dissipates heat to the to-be-charged device 10. Further, the central axis of the heat dissipation fan can coincide with the central axis of the transmitting and transmitting coil, so that the heat dissipation effect of the fan on the device 10 to be charged is good, and meanwhile, the heat dissipation of the transmitting coil is facilitated.
The charging control method in the present embodiment is described by taking the device to be charged 10 applied to fig. 1 as an example. Fig. 2 is a flowchart of a charging control method in one embodiment. In one embodiment, the charge control method includes steps 202, 204, and 206.
When the device to be charged detects that the device to be charged is connected with the wireless charging device and is in a wireless charging state, current charging environment information is acquired. The charging environment information refers to current external environment information of the device to be charged, and the charging environment information at least comprises an environment parameter and a time parameter.
The environment parameter refers to parameter information of one or more environment elements in the environment; the types of the environmental elements and the parameter information can be selected according to actual conditions. Optionally, the environment parameter is an environment brightness and an environment volume, where the environment volume refers to a sound volume other than the heat dissipation module noise, for example, a sound volume of a user speaking. Optionally, the ambient brightness is acquired by the light sensing component or the ambient volume is acquired by the sound sensing component.
The time parameter includes a time point or a time period corresponding to the current environment, for example, a certain time or a certain time period in a day. The time point or the time period can be set to different time units according to actual needs, for example, to "hour (h)" or to "minute (min)"; and in a different time format, for example, in "X month X day X hour" or "x.x.x". For example, if the time corresponding to the current charging environment is 0:30am in the morning, the time parameter may be recorded as 0:30am, or the time parameter may be recorded as morning. Optionally, when the device to be charged has a timing function, the read system time may be directly used as the time parameter.
Optionally, when the device to be charged detects that the device to be charged is connected with the wireless charging device and is in the wireless charging state, the current environmental parameter and the time parameter may be acquired intermittently or continuously. The parameter information is acquired in real time or in different time periods according to actual needs, so that the detection power consumption can be reduced, and the control cost is reduced to adapt to the actual requirements of users.
And step 204, acquiring the charging scene type according to the charging environment information.
And the equipment to be charged judges the charging scene type according to the acquired charging environment information, wherein the charging scene type is matched with the external environment of the equipment to be charged. The charging scene type at least comprises a noise-reduction and cooling charging scene and a cooling charging scene, the noise-reduction and cooling charging scene requires that the heat dissipation noise is reduced while the heat dissipation and cooling of the charging equipment are to be realized, and the cooling charging scene requires that the heat dissipation and cooling of the charging equipment are to be realized. The noise of the noise reduction and cooling charging scene is low, and the requirement that the noise needs to be reduced when a user has a rest or works is met.
Optionally, an environmental parameter and a time parameter corresponding to the charging scene type may be preset, and the corresponding charging scene type may be determined according to the environmental parameter and the time parameter. For example, when the environmental parameter is low environmental brightness and the time parameter is a night time period, determining that the corresponding charging scene type is a noise reduction and temperature reduction charging scene; and when the ambient brightness is high ambient brightness and the time parameter is the daytime time period, determining that the corresponding scene type is a cooling charging scene.
And step 206, sending a corresponding heat dissipation charging instruction to the wireless charging equipment according to the charging scene type.
The device to be charged generates a heat dissipation charging instruction corresponding to the charging scene type according to the charging scene type, and sends the heat dissipation charging instruction to the wireless charging device. Optionally, the device to be charged and the wireless charging device may perform wireless communication based on a wireless communication link, so as to send the heat dissipation charging instruction to the wireless charging device. The wireless communication link is not particularly limited. For example, the wireless charging device and the device to be charged may perform wireless communication based on a contactless IC card (radio frequency card), bluetooth (bluetooth), wireless fidelity (Wi-Fi), or backscattering (backscatter) modulation scheme (or power load modulation scheme).
The heat dissipation charging instruction is used for instructing the wireless charging equipment to adjust driving parameters for driving the heat dissipation module and charging parameters for wireless charging. The driving parameters influence the heat dissipation speed and the heat dissipation noise of the heat dissipation module, and specifically, the driving parameters are in direct proportion to the heat dissipation speed and the noise, and the larger the driving parameters, the faster the heat dissipation speed and the larger the noise. The charging parameters determine the charging power of the wireless charging, and affect the charging speed and the heat generation speed, specifically, the larger the charging parameters, the faster the charging speed, and the faster the heat generation speed.
The device to be charged generates a heat dissipation charging instruction corresponding to the charging scene type according to the charging scene type so as to instruct the wireless charging device to adjust the driving parameter and the charging parameter at the same time, so that the charging speed and the heat dissipation temperature can reach a certain balance, and the heat dissipation noise can be adjusted at the same time. For example, a corresponding heat dissipation charging instruction is generated in a noise reduction and cooling charging scene, so that the wireless charging equipment adjusts the driving parameters and the charging parameters to reduce the speed of heat dissipation noise and heat generation, the balance between the charging speed and the system temperature is ensured while the temperature is reduced, and the comfort and the safety are ensured.
According to the charging control method provided by the embodiment, when the wireless charging device is detected to be connected and in a wireless charging state, the current charging environment information is acquired, the charging scene type is acquired according to the charging environment information, and the heat dissipation charging instruction corresponding to the charging scene type is generated according to the charging scene type so as to instruct the wireless charging device to adjust the driving parameter and the charging parameter at the same time, so that the charging speed and the system temperature reach a certain balance, the heat dissipation of the system is realized, and the safety and the reliability of the system are improved; and the heat dissipation noise is adjusted while the system dissipates heat, so that the comfort of the environment is improved.
In one embodiment, referring to FIG. 3, step 204 includes step 302 and step 304.
And 304, if the environmental parameter does not meet the first preset condition and/or the time parameter does not meet the second preset condition, determining that the scene type is a cooling and charging scene.
When the environmental parameters are various, the first preset condition may include a plurality of parameter thresholds, the various environmental parameters are respectively compared with the corresponding parameter thresholds, and whether the environmental parameters satisfy the first preset condition is determined according to the comprehensive comparison result. When the relevant parameters of the environmental parameters are independent parameters, the first preset condition comprises an independent parameter threshold, and the independent parameter threshold is singly compared with the environmental parameters to judge whether the environmental parameters meet the first preset condition.
Optionally, the first preset condition includes that the ambient brightness is less than a brightness threshold; or, the ambient volume is less than the volume threshold. The second preset condition includes: the time parameter is within a time threshold. The time threshold range may be a specific time period, for example, 0:00 to 6:00, and the time parameter may be current time information; the time threshold range may also be a time range, for example, 30 minutes, 60 minutes, etc., and the time parameter may be a time difference between the current time and a previously set time.
The brightness threshold, the volume threshold, the time threshold range, and the like are set according to the specific lifestyle of the user.
For example, a noise reduction, temperature reduction and charging scene is preset as a user rest scene, and the user is generally in a range of 0:00-6: when the user has a rest in a time period of 00 and the ambient brightness required by the user for the rest is less than the value A, the brightness threshold value can be preset as the value A, and the ambient brightness is less than the value A under the first preset condition; the preset time threshold is 0:00-6:00, and the second preset condition is that the time parameter is in the range of 0:00-6: 00.
For example, a noise reduction, temperature reduction and charging scene is preset as a user rest scene, and the user is generally in a range of 0:00-6: a time period of 00 and a time period of 12:00-14:00 are used for rest, and the ambient brightness required by the user for rest is less than the value A, the brightness threshold value can be preset as the value A, and the ambient brightness is less than the value A under the first preset condition; the preset time threshold is 0:00-6:00 or 12:00-14:00, and the second preset condition is that the time parameter is in the range of 0:00-6:00 or in the range of 12:00-14: 00.
For example, the noise reduction scene of the user is preset as a rest scene, and the user is generally set at 0:00-6: a time period of 00 is at rest and the ambient brightness required at rest in that time period is less than the value a, and a time period of 12:00-14:00 is at rest and the ambient brightness required at rest in that time period is less than the value B, then: the first brightness threshold value is an A value, the first time threshold value is 0:00-6:00, the first preset condition is that the ambient brightness is smaller than the A value, and the second preset condition is that the time parameter is in the range of 0:00-6: 00; the second brightness threshold value is a value B, the second time threshold value is 12:00-14:00, the first preset condition is that the ambient brightness is smaller than the value B, and the second preset condition is that the time parameter is in a range of 12:00-14: 00.
In one embodiment, the charging scenario types include at least a noise reduction and temperature reduction charging scenario, and step 206 includes step 401.
Step 401, if the charging scene type is a noise reduction and temperature reduction charging scene, sending a first heat dissipation charging instruction to the wireless charging device. The first heat dissipation charging instruction is used for indicating the wireless charging equipment to adjust driving parameters and charging parameters within a preset range, the driving parameters at least comprise driving voltage, and the charging parameters at least comprise charging current.
Wherein, drive voltage can be used to control the radiating rate of heat dissipation module, for example, when heat dissipation module is radiator fan, drive voltage control radiator fan's rotational speed to control radiator fan's radiating rate and noise heat dissipation: the higher the rotating speed is, the higher the heat dissipation speed is and the higher the noise is; the smaller the rotation speed, the smaller the heat dissipation speed and the smaller the noise. The charging current is in direct proportion to the wireless charging power, and the larger the charging current is, the larger the power is, the faster the charging speed is and the more the heat is; the smaller the charging current, the lower the power, the slower the charging speed and the less heat.
In an embodiment, when the driving parameter is in direct proportion to the noise level and the charging parameter is in direct proportion to the heat level, the preset range is the driving parameter and the charging parameter smaller than the corresponding reference values in order to enable the wireless charging device to perform cooling and noise reduction according to the first heat dissipation charging command. The preset reference value is a critical value when the wireless charging equipment is wirelessly charged and does not need noise reduction, and when the driving parameters and the charging parameters are smaller than the corresponding reference values, the wireless charging equipment is in a noise reduction and cooling charging scene. Therefore, the driving parameters are smaller than the corresponding reference values, the heat dissipation speed is reduced, and the noise is reduced; meanwhile, the charging parameters are smaller than the corresponding reference values, the heat generation speed is reduced, and the timely heat dissipation can be ensured although the heat dissipation speed is reduced.
Specifically, the reference value at least comprises a reference driving voltage and a reference charging current, and the first heat dissipation charging instruction is used for instructing the wireless charging device to adjust the driving voltage to be smaller than the reference driving voltage and to adjust the charging current to be smaller than the reference charging current. When the driving voltage is smaller than the reference driving voltage and the charging current is smaller than the reference charging current, the wireless charging equipment charges the charging equipment and simultaneously reduces noise and temperature, the charging safety is guaranteed, meanwhile, the interference on the rest of a user is reduced, and the experience of the user is improved.
In an embodiment, the charging scenario types include at least a cool down charging scenario, see fig. 4, step 206 includes steps 402 and 404.
And the equipment to be charged judges the charging scene type to be a cooling charging scene according to the charging environment information, and obtains the temperature information of the equipment to be charged. The temperature information at least comprises a temperature value of the equipment to be charged in the wireless charging process, and the temperature value is related to the charging parameters of the wireless charging and the driving parameters of the heat dissipation module. The electric quantity information comprises the current charging electric quantity of the equipment to be charged, when the charging electric quantity is smaller, the wireless charging duration is shorter, the heat generated by the system is less, and the time for charging the equipment to be charged is longer; when the charging electric quantity is larger, the duration of wireless charging is longer, the heat generated by the system is more, and the time for charging the equipment to be charged is short.
And step 404, sending a corresponding heat dissipation charging instruction to the wireless charging device according to the temperature information and the electric quantity information.
The temperature information and the electric quantity information can embody the current heat dissipation condition and the charging condition, the equipment to be charged can divide various cooling scenes according to the temperature information and the electric quantity information, different cooling grades are obtained, and corresponding heat dissipation charging instructions are regenerated according to the cooling grades to match the cooling charging scenes of the various cooling grades, so that the heat dissipation efficiency is further improved.
Optionally, referring to fig. 5, step 404 includes step 502 and step 504.
Step 502, if the temperature information is greater than the temperature threshold and the electric quantity information is greater than the electric quantity threshold, a second heat dissipation charging instruction is sent to the wireless charging device.
In step 504, if the temperature information is less than or equal to the temperature threshold and the electric quantity information is less than the electric quantity threshold, a third heat dissipation charging instruction is sent to the wireless charging device.
When the temperature information is greater than the temperature threshold and the electric quantity information is greater than the electric quantity threshold, the duration of wireless charging is long and the heat generated by the system is large, the cooling grade is set to be one grade, the emergency degree of the indication cooling is large, therefore, a second cooling and charging instruction is generated, the corresponding parameter adjusting range is large, and the fast cooling speed is obtained. When the temperature information is smaller than or equal to the temperature threshold and the electric quantity information is smaller than the electric quantity threshold, the duration of wireless charging is shorter and the heat generated by the system is smaller, the cooling grade is set to be two grades, the emergency degree of indicating cooling is smaller, therefore, a third cooling and charging instruction is generated, the corresponding parameter adjusting amplitude is smaller, and the gentler cooling speed is obtained.
The temperature threshold and the power threshold are not limited, and may be set according to actual conditions, for example, the temperature threshold is set to be 30 ℃, and the power threshold is 80% of the battery capacity.
The second heat dissipation charging instruction is used for indicating the wireless charging equipment to adjust the driving parameter to be a first driving parameter value and adjust the charging parameter to be a first charging parameter value, the third heat dissipation charging instruction is used for indicating the wireless charging equipment to adjust the driving parameter to be a second driving parameter value and adjust the charging parameter to be a second charging parameter value, the driving parameter at least comprises driving voltage, and the charging parameter at least comprises charging current.
The first driving parameter value and the second driving parameter value are larger than or equal to reference values corresponding to the driving parameters, and the first charging parameter value and the second charging parameter value are larger than or equal to reference values corresponding to the charging parameters. The preset reference value is a critical value when the wireless charging equipment performs wireless charging and does not need noise reduction, and when the charging scene type is a cooling charging scene, the driving parameter and the charging parameter are greater than or equal to the corresponding reference values; and when the charging scene type is a noise reduction and temperature reduction charging scene, the driving parameters and the charging parameters are smaller than the corresponding reference values.
The first driving parameter value is larger than the second driving parameter value, so that the heat dissipation speed corresponding to the second heat dissipation charging instruction is larger than the heat dissipation speed corresponding to the third heat dissipation charging instruction; the first charging parameter value is smaller than or equal to the second charging parameter value, so that the power value corresponding to the second heat dissipation charging instruction is smaller than or equal to the power value corresponding to the third heat dissipation charging instruction. Therefore, in a cooling charging scene with more heat and higher temperature, the charging control system can be cooled rapidly under the regulation of the wireless charging equipment, so that the safety of the charging control system is improved; in a cooling charging scene with small heat and low temperature, the charging control system continuously keeps a high charging speed, and the charging efficiency is improved.
The charging control method in this embodiment is described by taking the wireless charging device applied to fig. 1 as an example. Fig. 6 is a flow chart of a charge control method in one embodiment. In one embodiment, the charge control method includes steps 602, 604, and 606.
When the wireless charging equipment wirelessly charges the equipment to be charged, the charging control system generates heat, and the wireless charging equipment controls the heat dissipation module to dissipate heat. The wireless charging device can wirelessly charge the device to be charged through the charging module; the heat dissipation module may be, for example, a heat dissipation fan, and the wireless charging device controls the rotation speed of the heat dissipation fan through the driving parameter, so as to dissipate heat.
When the wireless charging equipment detects that the wireless charging equipment is connected with the equipment to be charged and is in a wireless charging state, current charging environment information is acquired. The charging environment information refers to current external environment information of the wireless charging device, and the charging environment information at least comprises an environment parameter and a time parameter.
The environment parameter refers to parameter information of one or more environment elements in the environment; the types of the environmental elements and the parameter information can be selected according to actual conditions. The time parameter includes a time point or a time period corresponding to the current environment, for example, a certain time or a certain time period in a day.
Optionally, an optical sensing component is arranged in the wireless charging device to acquire ambient brightness or an acoustic sensing component is arranged in the wireless charging device to acquire ambient volume; optionally, when the wireless charging device has a timing function, the read system time may be directly used as the time parameter.
The wireless charging equipment judges the charging scene type according to the acquired charging environment information, and the charging scene type is matched with the external environment of the wireless charging equipment. The charging scene type at least comprises a noise-reduction and cooling charging scene and a cooling charging scene, the noise-reduction and cooling charging scene requires that the heat dissipation noise is reduced while the heat dissipation and cooling of the charging equipment are to be realized, and the cooling charging scene requires that the heat dissipation and cooling of the charging equipment are to be realized. The noise of the noise reduction and cooling charging scene is low, and the requirement that the noise needs to be reduced when a user has a rest or works is met. The setting of the noise reduction and temperature reduction charging scenario and the temperature reduction charging scenario may refer to the description of the embodiment in fig. 3, which is not described herein again.
The driving parameters influence the heat dissipation speed and the heat dissipation noise of the heat dissipation module, and specifically, the driving parameters are in direct proportion to the heat dissipation speed and the noise, and the larger the driving parameters, the faster the heat dissipation speed and the larger the noise. The charging parameters determine the charging power of the wireless charging, and affect the charging speed and the heat generation speed, specifically, the larger the charging parameters, the faster the charging speed, and the faster the heat generation speed.
The wireless charging equipment simultaneously adjusts the driving parameters and the charging parameters according to the charging scene type, so that the charging speed and the heat dissipation temperature can reach certain balance, and meanwhile, the heat dissipation noise is adjusted. For example, when a noise-reducing and temperature-reducing charging scene is performed, the driving parameters and the charging parameters are adjusted to reduce the speed of heat dissipation noise and heat generation, so that the balance between the charging speed and the system temperature is ensured while the temperature is reduced, and the comfort and the safety are ensured.
According to the charging control method provided by the embodiment, when the wireless charging equipment is used for wirelessly charging the equipment to be charged, the heat dissipation module is controlled to dissipate heat, the current charging environment information is obtained, the charging scene type is obtained according to the charging environment information, and then the driving parameters and the charging parameters are adjusted according to the charging scene type so that the heat dissipation speed and the charging speed are adjusted, so that the charging speed and the system temperature are balanced to a certain degree, and the charging and heat dissipation effects are realized so as to improve the charging safety and reliability; and meanwhile, the heat dissipation noise is adjusted to improve the comfort of the environment and improve the user experience.
In one embodiment, the charging scenario types include at least a noise reduction and temperature reduction charging scenario, and step 606 includes step 701.
Step 701, if the charging scene type is a noise reduction and temperature reduction charging scene, adjusting driving parameters and charging parameters within a preset range, wherein the driving parameters at least comprise driving voltage, and the charging parameters at least comprise charging current.
Wherein, drive voltage can be used to control the radiating rate of heat dissipation module, for example, when heat dissipation module is radiator fan, drive voltage control radiator fan's rotational speed to control radiator fan's radiating rate and noise heat dissipation: the higher the rotating speed is, the higher the heat dissipation speed is and the higher the noise is; the smaller the rotation speed, the smaller the heat dissipation speed and the smaller the noise. The charging current is in direct proportion to the wireless charging power, and the larger the charging current is, the larger the power is, the faster the charging speed is and the more the heat is; the smaller the charging current, the lower the power, the slower the charging speed and the less heat.
In one embodiment, when the driving parameter is proportional to the noise level and the charging parameter is proportional to the heat level, the predetermined range is set such that the driving parameter and the charging parameter are smaller than the corresponding reference values for reducing the temperature and reducing the noise. The preset reference value is a critical value when the wireless charging equipment is wirelessly charged and does not need noise reduction, and when the driving parameters and the charging parameters are smaller than the corresponding reference values, the wireless charging equipment is in a noise reduction and cooling charging scene.
