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 disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
FIG. 1 is a flow chart illustrating a method of charging in accordance with an exemplary embodiment; the method of the embodiment can be applied to terminal devices (e.g., smart phones, tablet computers, desktop computers, wearable devices, and the like).
As shown in fig. 1, the method comprises the following steps S101-S103:
in step S101, in response to detecting that the terminal device is connected to the charging apparatus, a current temperature of the terminal device is acquired.
In this embodiment, when the terminal device detects that the terminal device is connected to the charging device, the current temperature of the terminal device may be obtained.
For example, the terminal device connects the USB interface of the terminal device with a charging device (e.g., a charger) through a USB cable during charging, and the terminal device can determine whether to connect with the charging device by detecting a connection state of the USB interface.
In an embodiment, the current temperature of the terminal device may include an integrated value of temperatures measured around each component in the terminal device, and the integrated value may be used to reflect an overall temperature of the terminal device, which is not limited in this embodiment. In another embodiment, the current temperature of the terminal device may be determined in the following embodiment shown in fig. 5A, which will not be described in detail.
In step S102, a charging current of the terminal device is determined based on the current temperature and a pre-constructed relationship model between the charging current and the terminal temperature.
In this embodiment, after the current temperature of the terminal device is obtained, the charging current of the terminal device may be determined based on the current temperature and a pre-established relationship model between the charging current and the terminal temperature.
The relation model of the charging current and the terminal temperature can be obtained through statistical results of sample experimental data, and the relation model can be at least used for reflecting the temperature change condition of the terminal equipment during charging based on the charging currents of different gears under normal conditions.
For example, after the current temperature of the terminal device is obtained, the current temperature of the terminal device may be matched with a relation model between the charging current and the terminal temperature, so as to screen the charging current of the terminal device from the charging currents of different gears in the model. That is to say, in this embodiment, the temperature rise condition of the terminal device can be predicted through the relationship model between the charging current and the terminal temperature and the current temperature of the terminal device, and then the charging current of the terminal device is screened out from the charging currents of different gears based on the temperature rise condition, so as to ensure that a larger charging current is selected as far as possible under the condition that the temperature rise of the terminal device does not exceed the standard.
In another embodiment, the manner of determining the charging current of the terminal device based on the current temperature and the pre-constructed relationship model between the charging current and the terminal temperature may also be referred to the following embodiment shown in fig. 2, which will not be described in detail herein.
In step S103, the terminal device is charged based on the charging current.
In this embodiment, after the charging current of the terminal device is determined based on the current temperature and a pre-established relationship model between the charging current and the terminal temperature, the terminal device may be charged based on the charging current.
As is apparent from the above description, the method of the present embodiment obtains the current temperature of the terminal device by responding to the detection that the terminal device is connected to the charging apparatus, and determining the charging current of the terminal device based on the current temperature and a pre-constructed relation model of the charging current and the terminal temperature, and then the terminal equipment is charged based on the charging current, so that the charging current can be accurately determined based on the current temperature of the terminal equipment and a pre-constructed relation model of the charging current and the terminal temperature in the charging process, the temperature of the terminal equipment can be effectively prevented from rising too high in the charging process, the charging current of the terminal equipment does not need to be reduced greatly, the cooling speed of the terminal equipment can be improved, thereby, the influence on the charging speed of the terminal device due to the decrease in the charging current can be reduced.
FIG. 2 is a flow chart illustrating how the charging current of the terminal device is determined according to an exemplary embodiment of the present disclosure; the present embodiment is exemplified by how to determine the charging current of the terminal device on the basis of the above-described embodiments. As shown in fig. 2, the determining the charging current of the terminal device based on the current temperature and the pre-constructed relationship model between the charging current and the terminal temperature in the above step S102 may include the following steps S201 to S202:
in step S201, a charging current of the terminal device is determined based on the current temperature of the terminal device, the target temperature of the terminal device, and the relationship model.
In this embodiment, after the current temperature of the terminal device is obtained, the charging current of the terminal device may be determined based on the current temperature of the terminal device, the target temperature of the terminal device, and the relationship model.
Fig. 3 is a flowchart illustrating how to determine a charging current of the terminal device according to an exemplary embodiment of the present disclosure. As shown in fig. 3, the step S201 may further include the following steps S301 to S303:
in step S301, based on the current electric quantity of the battery of the terminal device, the capacity of the battery, and the relationship model, determining an expected time length for the terminal device to complete charging under the condition of charging based on different charging currents;
in step S302, determining an expected temperature of the terminal device when charging is completed based on the current temperature, the expected duration, and the relationship model;
in step S303, based on the comparison result between the expected temperature and the target temperature, the charging current of the terminal device is screened out from the different charging currents.
For example, when the current temperature of the terminal device is 30 ℃ and the set target temperature is 40 ℃, the predicted time for completing charging (i.e., fully charging the terminal device) when charging is performed based on the charging currents of different gears can be determined by combining the current capacity (e.g., 30% capacity) of the terminal device, the battery capacity (e.g., 5000mAh) of the terminal device and a pre-constructed relation model of the charging current and the terminal temperature, then, based on the present temperature of the terminal device and the estimated time, the estimated temperature at which charging is completed with the charging current of the different gear is estimated, therefore, the charging current of the terminal equipment can be screened from the different charging currents based on the comparison result of the expected temperature and the target temperature, namely, the charging current of the maximum gear which can meet the target temperature is selected.
In step S202, in response to detecting that the current temperature of the terminal device meets a set condition while the terminal device is charged based on the charging current, the charging current is adjusted.
In this embodiment, after the charging current of the terminal device is determined based on the current temperature of the terminal device, the target temperature of the terminal device, and the relationship model, the terminal device may be charged based on the charging current, then the current temperature of the terminal device may be detected based on a preset frequency in a charging process, and whether the current temperature meets a set condition is determined, and then the charging current may be adjusted when the current temperature of the terminal device is detected to meet the set condition.
The setting condition may be set based on actual needs, such as setting the setting condition to be higher than a setting threshold, and the like, which is not limited in this embodiment.
In another embodiment, fig. 4 is a flowchart illustrating how to determine that the current temperature meets a set condition according to an exemplary embodiment of the present disclosure. As shown in fig. 4, the present embodiment may determine that the current temperature of the terminal device meets the setting condition through the following steps S401 to S402:
in step S401, a target temperature of the terminal device is determined based on the current charging duration, the charging current, and the relationship model.
In step S402, in response to detecting that the difference between the current temperature and the target temperature is greater than or equal to a set threshold, it is determined that the current temperature meets a set condition.
For example, the terminal device may perform timing in the charging process, that is, count the charging duration of the terminal device in the current charging, and further query the relationship model based on the current charging duration and the current charging current to obtain the target temperature of the terminal device, that is, the temperature of the terminal device corresponding to the charging duration and the charging current in the relationship model. On the basis, the difference between the current temperature of the terminal equipment and the target temperature can be calculated and compared with a set threshold, and when the difference is detected to be greater than or equal to the set threshold, the current temperature can be determined to meet the set condition.
In an embodiment, the adjusting the charging current may include:
and gradually adjusting the charging current based on the set current adjustment amount until the current temperature of the terminal equipment is detected to be no longer in accordance with the set condition. That is, a smaller current adjustment amount (for example, several tens of milliamperes) may be preset, and when the charging current needs to be adjusted, the current adjustment amount may be reduced each time on the basis of the current charging current until it is detected that the current temperature of the terminal device meets the change trend shown in the relation model between the charging current and the terminal temperature, that is, the current temperature no longer meets the set condition.
As can be seen from the above description, in this embodiment, the charging current of the terminal device is determined based on the current temperature of the terminal device, the target temperature of the terminal device, and the relationship model, and the charging current is adjusted in response to the current temperature of the terminal device being detected to meet the set condition when the terminal device is charged based on the charging current, so that the charging current of the terminal device can be accurately determined, the temperature of the terminal device can be effectively prevented from rising too high during the charging process, and the cooling rate of the terminal device is increased.
Fig. 5A is a flowchart illustrating how to obtain a current temperature of the terminal device according to an exemplary embodiment of the present disclosure; the present embodiment takes how to obtain the current temperature of the terminal device as an example to illustrate on the basis of the above embodiments. As shown in fig. 5A, the obtaining of the current temperature of the terminal device in step S101 may include the following steps S501 to S502:
in step S501, values of temperature sensors preset around each heating device in the terminal device are obtained.
In this embodiment, when it is detected that the terminal device is connected to the charging device, values of the temperature sensors preset around the heating devices in the terminal device may be obtained.
The heat generating device may be set based on actual needs, such as at least one of the following:
battery, treater, charge mouthful, power management chip, charging chip and mainboard.
The type of the temperature sensor may be set based on actual business needs, such as a thermistor, and the like, which is not limited in this embodiment.
In step S502, the current temperature of the terminal device is fitted based on the values of the temperature sensors and preset weights.
In this embodiment, after obtaining the values of the temperature sensors preset around each heating device in the terminal device, the current temperature of the terminal device may be fitted based on the values of the temperature sensors and the preset weight.
Taking a mobile phone as an example, fig. 5B is a schematic diagram of a charging circuit of the mobile phone according to an exemplary embodiment of the disclosure. In this embodiment, a relation model between the charging current and the terminal temperature may be constructed according to structures such as the internal impedance of the battery and the internal circuit impedance to reflect the change of the terminal temperature corresponding to the charging current with time, and then, the maximum charging current that does not exceed the current temperature is determined by combining the current temperature of the mobile phone and the preset target temperature that does not affect the user experience, the charging is performed with the predicted maximum current in the whole process, and the charging current is finely adjusted based on the relation model in the charging process to ensure that the temperature rise of the mobile phone does not exceed the standard and that the charging current is large enough as far as possible, thereby improving the user experience.
The mobile phone charging circuit shown in fig. 5B, wherein the charger is connected to the mobile phone through a USB cable, the USB port is connected to each power management or charging chip through an internal circuit, the power management chip or the charging chip is connected to the battery through an internal circuit, and there are certain impedances in the whole connection circuit, the inside of the charging chip, and the inside of the battery, which can be calculated according to joule law (Q ═ I2 ^ R ^ t) during the charging process, and the heat Q is dissipated to the whole mobile phone.
