Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The embodiment of the disclosure provides a heat dissipation control method. The heat dissipation control method is applied to a charging auxiliary device, and the charging auxiliary device comprises a heat dissipation assembly. Fig. 1 is a flow chart illustrating a heat dissipation control method according to an exemplary embodiment, as shown in fig. 1, the control method includes the following steps.
In step S11, acquiring, by the charging assist device, a charging parameter of the device to be charged and a case temperature of the device to be charged;
in step S12, the heat sink assembly is activated when it is confirmed that the first preset condition is met based on the acquired charging parameter and the case temperature.
The disclosure provides a heat dissipation control method, which is applied to a charging auxiliary device, such as a back-clip charging device, wherein the charging auxiliary device acquires a charging parameter of a device to be charged and a shell temperature of the device to be charged, and when the acquired charging parameter and the shell temperature meet a first preset condition, a heat dissipation assembly of the charging auxiliary device is started. The heat dissipating component may be any component that can dissipate heat of the device to be charged, such as a fan.
The case temperature of the device to be charged may include the temperature of the back case. For example, when the device to be charged is charged by using the back clip charging device, the temperature of the back shell of the device to be charged can be acquired, and whether the device to be charged needs to dissipate heat can be accurately acquired.
The charging parameters may be charging parameters that affect charging of the device to be charged, and may include, for example, charging current, charging voltage, and charging power.
As the demand for the charging speed of the device to be charged is higher and higher, the charging power is also continuously increased. Therefore, the related state of the to-be-charged equipment, which needs to dissipate heat, needs to be acquired in time, so that the auxiliary charging device can open the heat dissipation assembly in time and dissipate heat of the to-be-charged equipment. In the disclosure, besides considering the shell temperature of the device to be charged in the charging process, the charging parameter that the device to be charged can affect the shell temperature of the device to be charged in the charging process is also considered, and the shell temperature and the charging parameter of the device to be charged in the charging process are monitored in real time, so that the operating state of the heat dissipation assembly is controlled according to the monitored charging parameter and the monitored shell temperature under the condition of meeting the preset condition.
According to the heat dissipation control method, when the charging auxiliary device is used for charging the equipment to be charged, and when the acquired charging parameter and the shell temperature of the equipment to be charged meet the first preset condition, the heat dissipation assembly is started to dissipate heat of the equipment to be charged, so that the phenomenon that the charging speed is influenced due to the fact that the temperature of the equipment to be charged is too high and even reaches the temperature limit in the charging process is avoided. According to the heat dissipation control method for the device to be charged in the charging process, whether the device to be charged needs to dissipate heat or not can be known in time by considering the shell temperature and the charging parameters of the device to be charged in the charging process, and the device to be charged can dissipate heat in time.
In the heat dissipation control method provided by the present disclosure, the device to be charged may include any device to be charged that can be charged, such as a mobile phone, a PAD, a computer, and the like.
The embodiment of the disclosure provides a heat dissipation control method. As shown in fig. 2, fig. 2 is a flowchart of a method for activating the heat dissipation assembly when it is confirmed that the first preset condition is met based on the acquired charging parameter and the case temperature in step S12 in fig. 1:
in step S121, when the charging parameter is greater than or equal to a first preset threshold and/or the casing temperature is greater than or equal to a second preset threshold, the heat dissipation assembly is started to operate at a preset speed;
in step S122, when the charging parameter is greater than or equal to a third preset threshold and/or the casing temperature is greater than or equal to a fourth preset threshold, the operation of the heat dissipation assembly is accelerated according to a first preset rule.
In the heat dissipation control method provided by the disclosure, two-stage judgment conditions are set in the charging process, wherein the first-stage judgment condition is that the charging parameter is greater than or equal to a first preset threshold value and/or the shell temperature is greater than or equal to a second preset threshold value, namely, when the judgment conditions are met, the heat dissipation assembly is started to operate at a preset speed. The second-stage judgment condition is that the charging parameter is greater than or equal to a third preset threshold and/or the shell temperature is greater than or equal to a fourth preset threshold, namely when the judgment condition is met, the operation of the heat dissipation assembly is accelerated according to a first preset rule.
When the charging parameter is greater than or equal to a first preset threshold and/or the shell temperature is greater than or equal to a second preset threshold, the heat dissipation assembly is started to operate at a preset speed, and when the charging parameter is greater than or equal to a third preset threshold and/or the shell temperature is greater than or equal to a fourth preset threshold, the operation of the heat dissipation assembly is accelerated according to a first preset rule. When the device to be charged is charged, the charging parameters and the case temperature are constantly changed as the charging time elapses. In the charging process, the charging parameters and the shell temperature are collected in real time, and when the charging parameters are larger than or equal to a first preset threshold value and/or the shell temperature is larger than or equal to a second preset threshold value, the heat dissipation assembly is started to dissipate heat of the device to be charged. When the charging parameter is greater than or equal to the third preset threshold and/or the shell temperature is greater than or equal to the fourth preset threshold, it is indicated that a large amount of heat is generated in the charging process, and the equipment to be charged needs to be cooled. When any one of the charging parameters and the shell temperature meets the corresponding preset condition, it is indicated that the equipment to be charged generates heat seriously in the charging process, and the heat dissipation force of the heat dissipation device needs to be further increased, so that the operation speed of the heat dissipation assembly needs to be accelerated according to a first preset rule so as to dissipate the heat of the equipment to be charged in time.
According to the heat dissipation control method provided by the disclosure, the operating speed of the heat dissipation assembly is set according to the state of the device to be charged in the charging process by setting two-stage judgment conditions, so that the heat dissipation assembly is effectively utilized to dissipate heat of the device to be charged.
The embodiment of the disclosure provides a heat dissipation control method. As shown in fig. 3, fig. 3 is a flowchart illustrating a method for activating the heat dissipation assembly when it is confirmed that the first preset condition is met based on the acquired charging parameter and the case temperature in step S12 in fig. 1:
in step S1211, when the charging parameter is greater than or equal to a first preset threshold, the heat dissipation assembly is started to operate at a preset speed;
in step S1221, when the casing temperature is greater than or equal to the fourth preset threshold, the operation of the heat dissipation assembly is accelerated according to the first preset rule.
In the heat dissipation control method provided by the present disclosure, when the device to be charged is charged, the charging parameter gradually increases along with the lapse of the charging time, for example, in the charging process, the charging current increases along with the increase of the charging power, which may cause the device to be charged to generate heat. In the charging process, the charging parameter first meets a first setting condition, that is, the charging parameter is greater than or equal to a first preset threshold, for example, the first preset threshold is 30 watts, and the charging power is greater than or equal to 30 watts. When the charging power meets the first preset condition, the heat dissipation assembly is turned on and operates at a preset speed, for example, at a system default speed of 1000 rpm. The heat dissipation assembly may include a fan, and the fan may operate at a preset speed to output wind power to dissipate heat of the device to be charged.
With further lapse of the charging time, the charging power is further increased, so that the heat generation of the device to be charged is further increased, the case temperature is increased, and the case temperature is equal to or higher than a fourth preset threshold value, for example, the fourth preset threshold value is 30 degrees, and the case temperature is equal to or higher than 30 degrees. The charging auxiliary device accelerates the operation of the heat dissipation assembly according to a first preset rule. When the temperature of the shell is greater than or equal to a fourth preset threshold value, the rotating speed of the fan is accelerated according to a first preset rule, and wind power is increased, so that heat dissipation is further performed on the to-be-charged equipment.
Of course, in the charging process, it may also be that the casing temperature is first greater than or equal to a second preset threshold, for example, the second preset threshold is 25 degrees, the casing temperature is greater than or equal to 25 degrees, and the charging auxiliary device starts the heat dissipation assembly to operate at a preset speed to charge the device to be charged. Over the charging time, the charging parameter is equal to or greater than a third preset threshold, for example, the charging parameter is charging power, the third threshold is 40 watts, and the charging power is equal to or greater than 40 watts. The charging auxiliary device accelerates the operation of the heat dissipation assembly according to a first preset rule.
In the heat dissipation control method for a device to be charged provided in the embodiments of the present disclosure, a first preset rule includes: the difference between the shell temperature and the reference temperature is positively correlated with the running speed of the heat dissipation assembly.
In the charging process, along with the lapse of charging time, treat that charging equipment's casing temperature is higher and higher, and when the difference with reference temperature is bigger and bigger, can make radiator unit's functioning speed increase gradually to increase the heat dissipation dynamics. When the difference value with the reference temperature is smaller and smaller, the running speed of the heat dissipation assembly can be gradually reduced, and the heat dissipation strength is reduced. The reference temperature may be a fourth preset threshold, that is, 30 degrees. But may be any set temperature.
The heat dissipation assembly may include a fan. When the difference value that the temperature of the shell is greater than the reference temperature is larger and larger, it is indicated that the temperature of the shell of the device to be charged is higher and higher, the heat dissipation of the shell of the device to be charged needs to be increased, and the output wind power of the fan needs to be increased. When the difference value that the shell temperature is greater than the reference temperature is smaller and smaller, the temperature of the shell of the device to be charged is gradually reduced, and the heat dissipation of the device to be charged can be realized without needing too large output wind power of the fan, so that the output wind power of the fan can be gradually reduced. The embodiment of the disclosure provides a method for controlling heat dissipation in a charging process of intelligent equipment. The intelligent equipment is applied to dynamic control of heat dissipation based on the charging auxiliary device under two charging scenes of constant-current charging and constant-voltage charging according to different charging scenes.
The heat dissipation control method provided by the disclosure is applicable to any scene which can cause the temperature of the device to be charged to be raised in the charging process, such as a Constant Current (CC) charging scene and a Constant Voltage (CV) charging scene in a high-power quick charging mode, when charging is started, the Constant Current charging mode is adopted, the Voltage of the battery is very low when charging is started, and if Constant Current charging is not carried out, the charging Current is very high, which can affect the service life of the battery of the intelligent device. When the intelligent device is charged quickly, a constant voltage charging mode is adopted, and the voltage value of the constant voltage is the terminal voltage value when the intelligent device is charged fully, so that the battery of the intelligent device is prevented from being overcharged.
Under the constant current scene of charging, when the charging parameter includes charging power, when the charging parameter is greater than or equal to first preset threshold, start the radiator unit and include according to the operation of presetting speed:
and if the charging power is greater than or equal to a first preset threshold value, starting the heat dissipation assembly to operate at a preset speed. In a constant current charging scenario, the current is large, the charging rate can reach 1.5C, 2C or 2.2C (for example, for a 4000mAh battery, 1C is 4000mA), and such an arrangement greatly shortens the charging time of the first 60% of the charging percentage. But high charge rate can lead to charging power very high, can make the equipment of waiting to charge seriously generate heat, and when the radiating efficiency is definite, the power of generating heat too big can lead to reaching the temperature restriction of equipment of waiting to charge easily to messenger's electric current falls, and the charge time of heavy current shortens, and the charging speed slows down.
According to the heat dissipation control method in the charging process of the device to be charged, in a constant-current charging scene, the charging power of the device to be charged is obtained, and when the charging power is larger than or equal to a first preset threshold value, for example, when the charging power is larger than or equal to 30 watts, the heat dissipation assembly of the device to be charged is started, and the heat dissipation assembly is started to operate at a preset speed. And in the constant-current charging stage, the shell temperature is also acquired, and when the shell temperature is greater than or equal to a fourth preset threshold value, for example, the shell temperature is greater than or equal to 30 ℃, the rotating speed of the heat dissipation assembly is accelerated according to a first preset rule.
In a constant-current charging scene, because the charging current is large, the charging power is high, if the charging power of the equipment to be charged is not effectively controlled, the temperature of the equipment to be charged can reach the temperature limit of the equipment to be charged quickly, so that the charging current falls off, and the large-current charging time is shortened. In the heat dissipation control method provided by the disclosure, the device to be charged is timely cooled through the judgment of the two-stage judgment condition, that is, when the charging power is greater than or equal to the first preset threshold, the heat dissipation assembly of the charging auxiliary device is timely started to timely reduce the temperature of the device to be charged, and when the shell temperature is greater than or equal to the fourth preset threshold, the heat dissipation assembly of the charging auxiliary device is timely accelerated to further reduce the temperature of the device to be charged. Through the mode, the charging speed is improved while the charging time of large current can be effectively prolonged.
In a constant voltage charging scenario, where the voltage is constant, the acquired charging parameters may include the charging power. In order to further assist the heat dissipation of the charging auxiliary device in a constant-voltage charging scene, the operation of the heat dissipation assembly can be adjusted according to a first preset rule when the charging parameter is greater than or equal to a third preset threshold value and/or the shell temperature is greater than or equal to a fourth preset threshold value, so as to assist the temperature reduction of the device to be charged.
The embodiment of the disclosure provides a method for controlling heat dissipation in a charging process of intelligent equipment. And stopping the heat dissipation assembly when the second preset condition is met based on the acquired charging parameter and the acquired shell temperature. And when the acquired charging parameters and the shell temperature meet second preset conditions, stopping the heat dissipation assembly of the charging auxiliary device so as to save the power consumption of the charging auxiliary device.
The embodiment of the disclosure provides a method for controlling heat dissipation in a charging process of intelligent equipment. As shown in fig. 4, fig. 4 shows that stopping the heat dissipation assembly when it is confirmed that the second preset condition is met based on the acquired charging parameter and the case temperature includes:
in step S13, when the charging parameter is smaller than a fifth preset threshold, decelerating the operation of the heat dissipation assembly according to a second preset rule;
in step S14, when the case temperature is less than a sixth preset threshold, the operation of the heat sink assembly is stopped.
When the device to be charged is charged, in a stage close to the completion of charging, for example, a constant voltage charging stage, the current starts to be gradually reduced, the power starts to be reduced, and at this time, the heating state of the device to be charged is gradually relieved, so that the operation of the heat dissipation assembly can be gradually reduced according to the actual charging condition, and the rotating speed of the heat dissipation assembly is reduced. When the charging parameter, such as the charging power, is less than the fifth preset threshold, the operation of the heat dissipation assembly may be decelerated according to the second preset rule. And when the shell temperature of the equipment to be charged is less than a sixth preset threshold, the operation of the heat dissipation assembly can be stopped so as to reduce the power consumption of the charging auxiliary device.
The fifth preset threshold may be the same as or different from the third preset threshold. For example, the fifth preset threshold may be 40 watts, 35 watts, or any other set value. The sixth preset threshold may be the same as or different from the second preset threshold, for example, the sixth preset threshold may be 25 degrees, 20 degrees, or any other set value.
The second preset rule may be the same as the first preset rule, that is, the rotation speed of the heat dissipation assembly is reduced in a manner that the difference between the shell temperature and the reference temperature is positively correlated with the operation speed of the heat dissipation assembly. The first preset rule may be different, and for example, the rotation speed of the heat dissipation assembly may be gradually decreased in steps at the same time period every interval.
As described above, the heat dissipation control method provided by the present disclosure may be applied to a high power fast charging mode. In the initial stage of charging in the high-power quick-charging mode, constant-current charging is generally used to increase the charging speed. In the scenario of constant-current charging, as described above, the charging current is large, the charging power is high, if the device to be charged is not timely cooled, the temperature limit of the device to be charged is likely to be quickly reached, and in order to ensure the safety of the device to be charged, the charging current drops, and charging is performed with relatively small current, as shown in fig. 5, fig. 5 shows a schematic diagram of the change of the current and voltage over time in a high-power quick-charging mode. Wherein the horizontal axis represents time in minutes. The left vertical axis represents current in amperes and the right vertical axis represents voltage in volts. The curve 3001 represents the state of change of the current during the charging process. The curve 3002 represents the state of change in voltage during charging. As shown in an exemplary diagram of the high power fast charging mode shown in fig. 5, in a constant current charging scenario, if the device to be charged is not cooled in time, due to the high power in the constant current charging scenario, the temperature of the device to be charged reaches the temperature limit when the charging time is about 5 minutes, the current starts to fall back, and the device to be charged is charged at a lower current value, so as to reduce the charging power and reduce the heat generation of the device to be charged.
In the heat dissipation control method provided by the disclosure, during charging overcharge, charging parameters, such as charging power, of a device to be charged and shell temperature of the device to be charged are acquired, and based on the charging parameters and the shell temperature, when it is confirmed that a first preset condition is met, a heat dissipation assembly of a charging auxiliary device is started. For example, when the charging power is greater than or equal to a first preset threshold, a heat dissipation component, such as a fan, is activated to operate at a preset speed to reduce the temperature of the device to be charged. When the shell temperature of the device to be charged is greater than or equal to a fourth preset threshold value, for example, the shell temperature is greater than or equal to 30 degrees, the heat dissipation assembly is accelerated according to a first preset rule, and when the difference value between the shell temperature and the reference temperature is larger, for example, 30 degrees, the rotating speed of the heat dissipation assembly is larger, so that the heat dissipation of the device to be charged can be fully performed. According to the heat dissipation control method provided by the disclosure, the temperature of the equipment to be charged in the charging process can be effectively controlled according to the two-stage condition judgment mode, the charging time of large current is prolonged, the charging speed is increased, and the charging time is shortened.
In the process of constant-voltage charging, at the initial stage of constant-voltage charging, when the charging parameter is greater than or equal to a third preset threshold and/or the shell temperature is greater than or equal to a fourth preset threshold, the operation of the heat dissipation assembly is adjusted according to a first preset rule so as to further assist the heat dissipation of the charging auxiliary device.
At the stage of constant voltage charging gradually approaching the charging completion stage, the current starts to be gradually reduced, the power starts to be reduced, and the heating state of the equipment to be charged is gradually relieved, so that the operation of the heat dissipation assembly can be gradually reduced according to the actual charging condition, and the rotating speed of the heat dissipation assembly is reduced. When the charging parameter, such as the charging power, is less than a fifth preset threshold, such as less than or equal to 40 watts, the operation of the heat dissipation assembly may be decelerated according to a second preset rule. When the casing temperature of the device to be charged is less than a sixth preset threshold value, for example, the casing temperature of the device to be charged is less than 20 degrees, the operation of the heat dissipation assembly may be stopped, so as to reduce the power consumption of the charging auxiliary device.
The embodiment of the disclosure provides a heat dissipation control method for a device to be charged in a charging process.
