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 implementations described in the exemplary embodiments below are not intended to represent all implementations 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.
The mobile terminal is provided with a rechargeable battery. When the rechargeable battery is not charged, the rechargeable battery is charged after a charger (or called charging adapter) is connected with the mobile terminal. Illustratively, the charging process includes the following stages: a pre-charge (pre-charge) stage (also known as trickle charge), a Constant Current (CC) charge stage, a Constant Voltage (CV) charge stage, and a charge termination stage.
The pre-charging phase refers to: when the voltage of the rechargeable battery is low, in order to avoid damage to the rechargeable battery caused by direct quick charging, the rechargeable battery is firstly charged with a low charging current to activate the rechargeable battery.
The CC charging phase refers to: the rechargeable battery is rapidly charged with a large and constant charging current, and the charging voltage is continuously increased during the CC charging.
The CV stage refers to: when the battery is substantially fully charged, the charging is continued with the voltage after the full charge of the battery as a constant voltage, and the charging current is continuously decreased during the CV charging.
Fig. 1 shows a block diagram of a charging system provided in an exemplary embodiment of the present disclosure. This charging system includes: mobile terminal 120 and charger 140.
The mobile terminal 120 includes: an Application Processor (AP)122, a charge management chip (charge IC)124, a rechargeable battery 126, and a thermistor 128. The application processor 122 is connected to a charge management chip 124, the charge management chip 124 is connected to a rechargeable battery 126, and the thermistor 128 is connected to the charge management chip 124. The application processor 122 and the charging management chip 124 are further connected to a charging interface on the mobile terminal 120. The positions where the thermistor 128 is disposed include, but are not limited to: at least one of a battery surface of the rechargeable battery 126, a body interior of the mobile terminal 120, a body surface of the mobile terminal 120, and a bezel position of the mobile terminal 120. Of these, the thermistor 128 is an optional component.
The charger 140 includes: a power plug terminal 142, a charging circuit 144, and a terminal plug terminal 146. The power plug section 142 is used to connect to a commercial power (e.g., 220V or 110V) socket, the charging circuit 144 is used to convert the commercial power into a charging current and a charging voltage, and the terminal plug end 146 is used to connect to the mobile terminal 120. The terminal plug terminal 146 may be various versions of USB interfaces or lighting interfaces, such as a Type-C Type USB interface.
Since the charging process may cause the rechargeable battery 126 to generate heat, in some embodiments, a temperature protection mechanism is disposed in the charging management chip 124 in the mobile terminal 120, and the temperature protection mechanism is used to protect the heat generated by the mobile terminal 120 from being too high.
Fig. 2 and 3 show a charging current diagram and a battery temperature diagram after triggering the temperature protection mechanism, respectively, and the thermistor 128 is used for measuring the surface temperature of the rechargeable battery 126 at predetermined time intervals, and when the surface temperature reaches a temperature threshold (for example, 40 degrees), the charging current is decreased by L, which is a temperature protection current adjustment value. When the surface temperature decreases to another temperature threshold (e.g., 38.5 degrees), the charging current is restored to the pre-decrease current value, and the above steps are repeated.
Since the charging current in the CC charging stage is large in the related art, the temperature of the rechargeable battery rises rapidly. When the surface temperature of the rechargeable battery triggers the temperature protection mechanism, the charging management chip 124 triggers the reduction of the charging current by generating a pulse current. The pulse trigger type is simple and rough to reduce the current value of the charging current, so that the overall charging time is delayed. An inappropriate metaphor is that the related art is equivalent to finding an "obstacle" too late and stepping on a "brake" too hard after contacting the obstacle.
Fig. 4 shows a flowchart of a charging method of a mobile terminal according to an exemplary embodiment of the present disclosure. The method may be performed by the charge management chip 124. The method comprises the following steps:
and the charging management chip acquires the current charging current and the current charging temperature at the current moment at regular time intervals. Illustratively, the fixed time interval is predetermined, or the fixed time interval is dynamically set. For example, dynamically set in a system update file by the operating system's server.
For example, the charging management chip obtains the current charging current at the current moment from the charging strategy in which the charging management chip is running, and obtains the current charging temperature through the thermistor.
The current charging temperature is at least one of a surface temperature of the rechargeable battery, a body temperature of the mobile terminal, a surface temperature of the mobile terminal, and a middle frame temperature of the mobile terminal.
the next time is a time after the current time. The next moment is a future moment. Illustratively, the next time is the current time + a fixed time interval.
And the charging management chip predicts the charging temperature at the next moment according to the current charging current and the current charging temperature at the current moment to obtain the predicted charging temperature at the next moment.
In step 406, when the predicted charging temperature at the next time reaches the temperature threshold, the present charging current is decreased.
The temperature threshold is a threshold for triggering temperature protection. In one example, the temperature threshold is 40 degrees celsius. The present disclosure does not limit the specific values of the temperature threshold. The temperature threshold is fixed or dynamically changed depending on the operating mode or ambient temperature.
When the predicted charging temperature at the next moment reaches the temperature threshold, the temperature protection mechanism is triggered at the next moment with a high probability, and the current charging current is reduced by the charging management chip at the moment so as to avoid triggering the temperature protection mechanism.
In summary, according to the method provided in this embodiment, the predicted charging temperature at the next time is obtained by predicting according to the current charging current and the current charging temperature at the current time, and when the predicted charging temperature at the next time reaches the temperature threshold, the current charging current is reduced in advance, so that the temperature can be kept constant without triggering temperature protection, and therefore, the charging is completed as quickly as possible without triggering a temperature protection mechanism.
Fig. 5 shows a flowchart of a charging method of a mobile terminal according to an exemplary embodiment of the present disclosure. The method may be performed by the charge management chip 124. The method comprises the following steps:
and the charging management chip acquires the current charging current and the current charging temperature at the current moment at regular time intervals. Illustratively, the fixed time interval is predetermined, or the fixed time interval is dynamically set. For example, dynamically set in a system update file by the operating system's server.
For example, the charging management chip obtains the current charging current at the current moment from the charging strategy in which the charging management chip is running, and obtains the current charging temperature through the thermistor.
The current charging temperature is at least one of a surface temperature of the rechargeable battery, a body temperature of the mobile terminal, a surface temperature of the mobile terminal, and a middle frame temperature of the mobile terminal.
the charging management chip stores a charging temperature curve of the mobile terminal, and the charging temperature curve is used for describing the change of the temperature of the mobile terminal along with time under a certain charging current. For example, the charging temperature curves are multiple, and the charging current corresponding to each charging temperature curve is different. For example, the first charging temperature curve is a curve in which the temperature of the mobile terminal increases with time when the charging current is a 1; the second charging temperature curve is a curve in which the temperature of the mobile terminal increases with time when the charging current is a 2; the third charging temperature curve is a curve in which the temperature of the mobile terminal increases with time when the charging current is a3, and so on, and is not described in detail.
Illustratively, the charging temperature curve is characterized by at least one of a function, a curve, a data table and a mathematical model, and the embodiment of the disclosure does not limit the form of the characterization of the charging temperature curve.
illustratively, the charging management chip selects a charging temperature profile corresponding to the present charging current, which is a profile between time and temperature, according to the current value of the present charging current. And determining a first moment in a charging temperature curve according to the current charging temperature, adding the first moment and a fixed time interval to obtain a second moment, and determining the corresponding temperature of the second moment in the charging temperature curve as the predicted charging temperature of the next moment.
when the temperature threshold is reached, go to step 505; when the temperature threshold is not reached, step 510 is entered, and the present charging current is kept unchanged.
Step 505, when the predicted charging temperature at the next moment reaches the temperature threshold, the current charging current is reduced by a preset value to obtain the ith candidate charging current;
the preset value is smaller than a temperature protection current adjustment value, and the temperature protection current adjustment value is a current value which is reduced when the current charging current reaches a temperature threshold value. That is, the preset value is a smaller adjustment step value.
The charging management chip reduces the current value of the current charging current by a preset value to obtain the ith candidate charging current.
the charging management chip acquires a charging temperature curve of the mobile terminal; and determining the candidate predicted charging temperature at the next moment in the charging temperature curve according to the current charging current and the current charging temperature at the current moment.
Illustratively, the charging management chip selects a charging temperature profile corresponding to the ith candidate charging current, which is a profile between time and temperature, according to the current value of the ith candidate charging current. And determining a first moment in a charging temperature curve according to the current charging temperature, adding the first moment and a fixed time interval to obtain a second moment, and determining the corresponding temperature of the second moment in the charging temperature curve as the predicted charging temperature of the next moment.
when the temperature threshold is reached, go to step 508; when the temperature threshold is not reached, step 509 is entered to keep the present charging current constant.
and 510, charging by the reduced charging current.
Fig. 6 and 7 are a charging current chart and a battery temperature chart, respectively, when the charging method of the present embodiment is employed. Compared with the related art, it can be seen that the total charging time period of the charging method of the present embodiment can be shortened.
In summary, according to the method provided in this embodiment, the predicted charging temperature at the next time is obtained by predicting according to the current charging current and the current charging temperature at the current time, and when the predicted charging temperature at the next time reaches the temperature threshold, the current charging current is reduced in advance, so that the temperature can be kept constant without triggering temperature protection, and therefore, the charging is completed as quickly as possible without triggering a temperature protection mechanism.
The present embodiment also gradually reduces the present charging current by a smaller predicted value, and keeps a higher charging current as much as possible without triggering the temperature protection mechanism. The charging current is reduced by a small amount in advance, an obstacle is predicted in advance, the brake is stepped on in advance, the temperature is kept constant stably without triggering temperature protection, and therefore the charging time is guaranteed to be as short as possible.
In one example, the charging temperature profile is determined according to a battery model and a heat dissipation model of the mobile terminal. The developer can determine through at least one of a known (or measured) battery model, a heat dissipation model, and a charging circuit model during the development of the mobile terminal. As shown in fig. 8:
(1) when building a battery model, a developer needs to know basic information of a rechargeable battery (battery cell), which includes but is not limited to at least one of the following information: battery capacity, slow charge voltage, open circuit voltage-state of charge (OCV-SOC) curve, battery temperature, and degree of aging. Then, a battery model is constructed according to the basic information of the rechargeable battery.

Then, a heat dissipation model is constructed according to the basic information of the mobile terminal.
(3) When the charging circuit model is constructed, research and development personnel need to know the model selection and the performance parameters of the charging management chip or the application processor, and the charging circuit model is constructed according to the model selection and the performance parameters.

It should be noted that the charging method provided in the embodiment of the present disclosure is based on the fine adjustment of the current charging current after predicting the charging temperature in the charging process in the related art, and does not change the charging stages (the pre-charging stage, the CC charging stage, and the CV charging stage) of the mobile terminal. Any stage in the whole charging process is possible to be combined with the charging method provided by the embodiment of the disclosure to adjust the charging current.
