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.
Fig. 1 is a flowchart illustrating a mobile terminal charging control method according to an exemplary embodiment, which may be applied to a mobile terminal, as shown in fig. 1, and may include the following steps.
In step S11, a power output parameter of the charging device is acquired.
In step S12, a first charging path corresponding to the power output parameter is determined among a plurality of charging paths of the mobile terminal.
In step S13, a first charging current is obtained, where the first charging current is a charging current corresponding to the first charging path at a preset charging temperature.
In step S14, the mobile terminal is charged based on the first charging current and the first charging path.
For example, in step S11, the charging device may be a charger (also called a power adapter) of the mobile terminal, and the charging device may be an original charging device produced by a manufacturer of the mobile terminal, may also be a charging device provided by a third party manufacturer for the mobile terminal, and may also be a user charging the current mobile terminal by using original charging devices of other brands, so that one mobile terminal may use different models of charging devices. Charging equipment of different models can output different electric energy output parameters to the mobile terminal after being connected with the power supply and the mobile terminal, and the electric energy output parameters can include a current value and a corresponding voltage value under normal conditions. For example, a common charging device has a power output parameter of 5V/1a,5V/2A, and in order to meet the demand of faster charging of a user, there is also a charging device having a power output parameter of 9V/2A, 12V/1.5A.
After the charging equipment is accessed to the mobile terminal through the data transmission line, the mobile terminal can obtain the electric energy output parameters of the charging equipment and match the corresponding charging path according to the obtained electric energy output parameters.
In step S12, it can be understood that, when charging is performed, the battery of the mobile terminal has a corresponding rated voltage, but the input voltage corresponding to different power output parameters input by different charging devices is also different, and when charging is performed by using a non-standard charging device, the input voltage may not match the rated voltage of the battery of the mobile terminal, and may cause damage to the battery, resulting in temperature abnormality. In order to adapt to different Charging devices, a plurality of Charging paths are usually preset in the mobile terminal, each Charging path is configured with a different Charging IC (Charging Integrated Circuit Chip) according to different voltage regulation functions, and the Charging IC is configured with a regulation loop capable of regulating an input voltage to a rated voltage matched with a battery. The charging paths in the mobile terminal all charge the same battery, and when different electric energy is input through different charging devices, the input electric energy needs to be adjusted to the rated voltage allowed by the battery by using the corresponding charging paths. Illustratively, when the power output parameter of the charging device is 9V/2A, for a mobile terminal with a battery rated voltage of 5V, a step-down charging path is required to be applied to charge the mobile terminal; when the electric energy output parameter is 5V/1A and the battery input rated voltage of the mobile terminal is 12V, the mobile terminal needs to be charged by applying a boosting charging path. Therefore, the adaptive charging path can be selected from the mobile terminal to charge the mobile terminal by reading the electric energy output parameter of the charging device and comparing the electric energy output parameter with the system load parameter of the mobile device.
By adopting the embodiment, the mobile terminal can be compatible with different charging devices, adaptation is carried out according to the electric energy output parameters, the operation is simpler, more convenient and more accurate, and the scheduling burden can not be caused to the mobile terminal.
Optionally, in the first embodiment, the step S12 may include:
in step S121, one or more charging paths matching the power output parameters in the mobile terminal are obtained.
In step S122, in the case where there is one charging path matching the power output parameter, it is determined that the charging path matching the power output parameter is the first charging path.
In step S123, in the case where there are a plurality of charging paths matching the power output parameter, the charging path with the highest charging efficiency among the plurality of charging paths is determined as the first charging path.
It can be understood that the charging path in the mobile terminal is provided in multiple embodiments, wherein one or more boost charging paths and one or more buck charging paths may be provided according to the actual application requirement. The method includes the steps that electric energy output parameters input by charging equipment are read, corresponding input voltage is determined, the input voltage is compared with rated voltage of a battery in the mobile terminal, and one or more matched charging paths are determined.
When the corresponding charging path is a charging path, charging the mobile terminal by adopting the charging path; when the number of the corresponding charging paths is multiple, the multiple charging paths can be further screened according to different charging functions, for example, in order to meet the faster charging requirement of a user, the charging path with the highest charging efficiency in the multiple charging paths is determined as the target charging path. When the charging paths are configured, the charging efficiency of each charging path is calculated and determined according to circuit elements and connection modes in the charging paths.
It will be appreciated that the charging efficiency of the charging path is the ratio of the power input to the battery power of the mobile terminal battery, for example, charging efficiency = battery power/power input power, since the impedance in the charging path and the charging IC will dissipate the input power by heat loss before entering the battery. Fig. 2 is a schematic diagram of a charging path of a mobile terminal in the present disclosure, referring to the charging path shown in fig. 2, the power loss power is resistance heat loss power generated in a process that electric power reaches a battery through circuit elements such as a connection line 1, a connector 1, a connection line 2, a connector 2, and a charging IC, and the charging efficiency of the charging path can be calculated according to impedance in each circuit element and intrinsic efficiency of the charging IC, and for example, may be calculated by: charge efficiency = (power input power-resistive heat loss power-charging IC dissipation power)/power input power.
In practical applications, in order to reduce heat loss and enable the mobile terminal to realize efficient and rapid charging, a charging path with the highest charging efficiency is generally selected to charge the mobile terminal on the premise of meeting charging load conditions.
In step S13, during the charging process of the mobile terminal, part of the electric energy is converted into chemical energy of the battery, and part of the electric energy is converted into heat energy, the heat energy is discharged to raise the temperature of the housing of the mobile terminal, and a proper temperature rise process belongs to a normal charging phenomenon, but different temperature rise effects are caused by external connection of different charging devices, when a charging device with large output electric energy is externally connected, abnormal temperature rise occurs in the mobile terminal, and the mobile terminal may explode when the temperature is too high; when the charging equipment with lower output electric energy is externally connected, the current of the input battery corresponding to the mobile terminal is lower, so that the charging time is too long, and the corresponding temperature is lower than the standard temperature. Optionally, in order to reduce the temperature difference when the mobile terminal is adapted to different charging devices and prevent the charging temperature from being abnormal, the charging current, the charging voltage and the charging path in the normal charging state need to be obtained, so as to calculate and obtain the charging temperature corresponding to the standard charging path in the mobile terminal in the standard charging state, and use the charging temperature as the preset charging temperature, so as to ensure that the mobile terminal is charged at the preset charging temperature and ensure the charging safety. The normal charging state may be a charging state when the mobile terminal is connected to the power supply through a standard charging device, and at this time, the mobile terminal is charged through a standard charging path in the mobile terminal.
It can be understood that the charging temperature is generated by converting electric energy into heat energy when the electric energy passes through impedance in the charging path during the charging process, and therefore, the heat loss power corresponding to the charging path at the preset charging temperature can be calculated through a thermodynamic calculation formula. According to the charging path determined in the step, the impedance corresponding to each circuit element in the charging path is determined, so that the total impedance of the charging path is obtained, and therefore the formula P = I is used according to the heat loss power and the total impedance of the charging path 2 And R can calculate the corresponding current, namely the charging current corresponding to the charging path at the preset charging temperature can be obtained.
For example, before the mobile terminal is shipped and assembled, a manufacturer can determine a standard charging path and a standard charging current of the mobile terminal according to relevant charging parameters of the mobile terminal, and charge the mobile terminal through the standard charging path and the standard charging current, so that efficiency maximization can be achieved. Therefore, the preset charging temperature is the temperature of the charging path of the mobile terminal when the mobile terminal is charged by applying the standard charging path and the standard charging current, and the temperature can be obtained by measurement in addition to the calculation. Therefore, the actual charging current corresponding to the actual charging path can be calculated and obtained according to the corresponding relation between the charging efficiency of the standard charging path and the standard charging current under the premise of the same temperature.
Optionally, in the first embodiment, the step S13 may include:
and acquiring a mapping relation between the charging paths and the charging currents, wherein the mapping relation comprises a plurality of charging currents corresponding to the plurality of charging paths at a preset charging temperature.
And determining a first charging current corresponding to the first charging path according to the mapping relation.
It can be understood that, when the charging temperature is constant, the heat loss power corresponding to the charging path at this time may be calculated and determined according to the corresponding relationship between the charging temperature and the heat generation amount, and the charging voltage of the mobile terminal battery is adjusted by the loop of the charging IC in the charging path, and then the battery is charged by using the rated voltage, so that the charging current corresponding to each charging path is calculated and obtained according to the heat loss power, the rated voltage and the impedance of the charging path, and thus a mapping relationship between the charging path and the charging current at the preset charging temperature may be established.
Optionally, referring to fig. 3, fig. 3 is a schematic flowchart of a method for acquiring a charging current in a charging control method of a mobile terminal according to the present disclosure, and step S13 includes:
in step S131, a first charging efficiency corresponding to the first charging path is obtained.
In step S132, a second charging current and a second charging efficiency of a standard charging path of the mobile terminal at a preset charging temperature are determined, where the standard charging path is a charging path of the mobile terminal when the mobile terminal is charged by using a standard charging device.
In step S133, a first charging current corresponding to the first charging path is obtained based on the first charging efficiency, the second charging efficiency, and the second charging current.
For example, in step S131, the charging efficiency of the charging path is a ratio between the power of the battery and the power of the input electric energy, and the electric energy is consumed by the charging IC in the charging path and is finally transferred to the battery to be converted into the stored electric energy. Thus, the charging efficiency can be calculated from the impedance in the charging path and the efficiency of the charging IC, for example, referring to the charging path shown in fig. 2, where the charging efficiency of the charging path is:
η＝(U 1 I 1 -I 1 2 R 1 -I 1 2 R IC (1-η IC )-I 2 2 R 2 )/U 1 I 1
wherein eta is the charging efficiency of the charging path, U 1 、I 1 Respectively input voltage and input current, R 1 Is the impedance, R, of the connector 1 and the connecting line 1 IC For charging impedance, η, in IC IC Efficiency of conversion of electric energy to the charging IC (the efficiency of conversion of electric energy to the charging IC is an inherent property of the charging IC and can be obtained by identifying the charging IC), I 2 For charging the battery by conversion of the charging IC, R 2 The charging efficiency of the charging path is calculated from the above equation, which is the impedance between the connector 2 and the connection line 2. Wherein, U 1 I 1 Power is input for the electrical energy of the charging device,
for the resistive heat loss power of the connector 1 and the connecting line 1 in the charging path, is preset>
For the power consumption of the charging IC, in>
For resistive heat dissipation power, U, of the connector 2 and the connection line 2 in the charging path 1 I 1 Is the incoming power of the mobile terminal battery.
Optionally, step S131 includes:
in step S1311, a first connection impedance and a first heat loss efficiency corresponding to the first charging path are obtained.
In step S1312, a first charging efficiency is obtained based on the first connection impedance, the first heat loss efficiency and the power output parameter.
It can be understood that the first thermal waste efficiency is the thermal waste efficiency of the charging IC in the first charging path, the overall thermal waste power of the first charging path can be calculated according to the impedance parameter of the charging IC and the impedance parameters of the other resistors of the first charging path, the electric energy output power can be calculated according to the electric energy output parameter, and the charging efficiency corresponding to the first charging path can be calculated through the thermal waste power and the electric energy output power.
Optionally, step S1312 may include:
first, according to the electric energy output parameter and the first connection impedance, first impedance heat loss and first incoming power corresponding to the first charging path are obtained.
Secondly, a first charging efficiency is obtained according to the first heat loss efficiency, the first impedance heat loss and the first incoming power.
Illustratively, the charging efficiency is calculated through the electric energy output parameters, the battery charging power input into the battery is calculated and obtained through the impedance and the connection mode of each circuit device in the charging path, and then the charging efficiency corresponding to the charging path can be obtained according to the heat loss efficiency of the charging IC in the charging path and by combining the following formula:
wherein eta is charging efficiency corresponding to the charging path, I 1 For a current parameter of the input electric energy, R 1 Is the impedance, R, of the connector 1 and the connection line 1 IC For charging impedance, η, in IC IC Electric energy conversion efficiency for charging IC (electric energy conversion efficiency for charging IC is an inherent property of charging IC, and can be obtained by identifying charging IC), I 2 For charging the battery by conversion of the charging IC, R 2 The impedance of the connector 2 and the connecting line 2 can be calculated according to the above formula to obtain the charging efficiency corresponding to the charging path.
In step S132, it is understood that, in order to maximize the charging efficiency and optimize the charging performance of the mobile terminal, one of the charging paths is generally selected from the mobile terminal as a standard charging path before factory shipment, and a standard charging current is correspondingly configured to adapt to the standard charging device, where when the standard charging device is connected to the power supply and the mobile terminal is charged by using the standard charging path and the standard charging current, the temperature of the housing of the mobile terminal is the preset charging temperature. Therefore, through the identification calculation of each impedance and the charging IC in the standard charging path, the corresponding charging efficiency can be obtained.
In step S133, in the case of the same charging temperature, the charging efficiency in the identified actual charging path is substituted into the correspondence relationship between the standard charging efficiency and the standard charging current in the standard charging path, so as to calculate the actual charging current corresponding to the actual charging path.
Alternatively, the calculation may specifically be obtained by the following formula:
in which I 2 Is a first charging current, I 1 Is a second charging current, η 1 For the second charging efficiency, eta 2 Is a first charging efficiency. Therefore, under the condition that the second charging current, the second charging efficiency and the first charging efficiency are obtained, the first charging current corresponding to the first charging path can be calculated.
Optionally, the method further comprises:
in step S15, after a first charging path corresponding to the power output parameter is determined among the plurality of charging paths of the mobile terminal according to the power output parameter, it is determined whether the first charging path is a standard charging path.
In step S16, when it is determined that the first charging path is not the standard charging path, a step of obtaining a first charging current corresponding to the first charging path according to a preset charging temperature and charging the mobile terminal based on the first charging current and the first charging path is performed.
In step S17, in a case where the first charging path is determined to be the standard charging path, a standard charging current corresponding to the standard charging path is obtained, and the mobile terminal is charged based on the standard charging current and the standard charging path.
It can be understood that, after the parameter information of the first charging path is acquired through the scheme, the parameter information is compared with the parameter information corresponding to the standard charging path, and whether the actual charging path obtained through screening is the standard charging path is judged; when the actual charging path is the standard charging path, the mobile terminal can be charged by directly applying the standard charging path and the standard charging current; when the actual charging path is not the standard charging path, the actual charging current is calculated and obtained according to the method provided in the scheme and the corresponding relation between the charging current and the charging efficiency in the standard charging path.
According to the steps, whether the actually selected charging path is the standard charging path or not is identified, and when the actually selected charging path is determined to be the standard charging path, the standard charging current is directly used for charging the mobile terminal without the conversion relation between the charging efficiency and the charging current, so that the charging control method is more efficient and practical.
In step S14, after the charging current in the actual charging circuit is obtained through the above steps, the charging IC in the actual charging path is controlled to perform current conversion according to the actual charging current, specifically, the input current may be converted into the actual charging current according to a current regulation loop in the charging IC, and the battery is charged according to the actual charging current.
The embodiment of the disclosure provides a mobile terminal charging control method, and according to the embodiment, electric energy output parameters of charging equipment are obtained, a corresponding charging path is determined in a plurality of charging paths in a mobile terminal, and a charging current corresponding to the charging path at a preset charging temperature is obtained, and the mobile terminal is charged based on the charging current. Thereby can realize different charging schemes according to the different charging route of different battery charging outfit adaptations to charge for mobile terminal through the charging current who corresponds with the temperature of predetermineeing charging, temperature when can controlling to charge compares in prior art and need not to set up different charging agreements for different battery charging outfits, realizes simpler, consequently can be under the condition that does not increase the debugging cost, avoids the charging temperature abnormal problem because of adopting different battery charging outfits to lead to.
