Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In view of the foregoing problems, embodiments of the present application provide a first charging control method, apparatus, computer-readable storage medium, and terminal, which can improve the efficiency of charging control of the terminal. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a charging control method according to an embodiment of the present disclosure. The charging control method may be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palmtop computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers.
Specifically, the terminal includes a first battery, a second battery, a resistor, a first switch, a second switch, and a third switch, please refer to fig. 2, and fig. 2 is a schematic connection diagram of circuit components of a charging control method according to an embodiment of the present disclosure. One end of the first battery is connected with the resistor through the first switch, the other end of the first battery is connected with the second battery through the third switch, and one end of the second battery is connected with the resistor through the second switch. The specific flow of the charging control method can be as follows:
101. and when the charging power supply is detected to be connected, acquiring the voltage at two ends of the resistor.
In this embodiment, specifically, there may be a plurality of ways to detect whether to access the charging power supply, for example, whether current exists in the charging access port of the terminal or whether a magnetic field exists in the internal coil of the terminal may be detected. The access mode of the charging power supply may include multiple modes, for example, the access mode of the charging power supply may include wired access or wireless access.
The wireless charging mode can be an electromagnetic induction mode, a magnetic resonance mode, an electric field coupling mode, a radio wave transmission mode and the like, and the electromagnetic induction principle is mostly adopted for the wireless charging of the mobile phone. The electromagnetic induction type wireless charging mode is characterized in that when current of a power supply passes through a coil (a power transmission coil of a wireless charger), a magnetic field is generated, and other coils (power receiving coils at the mobile phone end) which are not electrified are close to the magnetic field, so that current is generated to charge the mobile phone.
Specifically, the wired access may be to charge the terminal by connecting a charging wire of the terminal with a fixed power supply or a mobile power supply, and the wireless charging may be to perform a charging operation by contacting a charging device with a built-in power transmission coil with the terminal.
Further, when the terminal is detected to be connected with a power supply, the voltage values at two ends of the resistor are obtained. Specifically, the voltage value across the resistor may be read through the charging circuit module, and the voltage value across the resistor may include a first voltage value and a second voltage value. For example, the first voltage value may be 1V (volts) or the like, and the second voltage value may be 2V or the like.
102. The charging current is determined based on the voltage and the resistance value.
Specifically, the access current can be transmitted to the battery through the resistor, and when the current of the access power supply is determined, the current can be obtained by processing the voltage at two ends of the resistor and the resistance value of the resistor.
In some embodiments, the step of "determining the charging current based on the voltage and the resistance value" may include the following process:
acquiring the resistance value;
determining a difference value between the first voltage and the second voltage to obtain a voltage difference value;
obtaining the ratio of the voltage difference value to the resistance value based on the resistance value and the voltage difference value;
determining the charging current according to the ratio.
The resistance value is obtained, the resistance may be a fixed resistance, the resistance value may be stored in the terminal in advance, and the obtained resistance value may be directly read from the memory. For example, the resistance value may be 1 Ω (ohm) or the like.
After the resistance value, the first voltage value and the second voltage value are obtained, the resistance value, the first voltage value and the second voltage value may be processed according to a preset rule to obtain the charging current. The preset rule may be a calculation method, for example, the calculation method may be that I ═ Va1-Va2)/Ra, where I may be represented as a charging current; va1 may represent a first voltage value, which may be 3V; va2 may represent a second voltage value, which may be 1V; ra may represent a resistance value, which may be 1 Ω, and the charging current I may be calculated to be 2A (amperes).
103. The charging current is compared to a preset threshold.
Specifically, after the charging current is determined, the charging current may be compared with a preset threshold. The preset threshold may be a charging current threshold determined in an experiment, that is, the charging current below the preset threshold may charge the terminal battery normally without affecting the battery performance.
For example, the access current may be 1A, 2A, etc., the preset threshold may be 1.5A, and when the access current is 1A, it may be determined that the access current is smaller than the preset threshold; when the access current is 2A, it can be determined that the access current is greater than the preset current.
104. And if the charging current is larger than the preset threshold value, acquiring the state of the first switch or the second switch, and switching the state of the first switch or the second switch according to the state.
Specifically, when the charging current is larger than a preset threshold, the current state of the first switch or the second switch may be obtained, and the state of the first switch or the second switch may be switched based on the current state. The two ends of the first switch can be respectively connected with the resistor and the first battery, and the two ends of the second switch can be respectively connected with the resistor and the second battery.
For example, the first switch may include an a terminal and a B terminal, wherein the a terminal may be connected to the resistor, and the B terminal may be connected to the first battery; the second switch may include a terminal C and a terminal D, wherein the terminal C may be connected to the resistor, and the terminal D may be connected to the second battery.
In some embodiments, the step of "obtaining a state of the first switch or the second switch, and switching the state of the first switch or the second switch according to the state" may include the following steps:
acquiring a first state of the first switch;
performing a state switching operation on the first switch and the second switch based on the first state.
Specifically, the first state of the first switch is obtained, and the first state may be a plurality of states, for example, the first state may be an open state or a closed state, where an open-to-state transition may indicate that a circuit where the first switch is open is opened, and a closed state may indicate that a circuit where the first switch is connected is closed.
Specifically, the state switching operation may be performed on the first switch and the second switch according to the first state of the first switch. For example, the first state may be open or closed, and when the first state is open, the first switch state may be switched to the closed state and the second switch state may be switched to the open state; when the first state is closed, the first switching state may be switched to an open state and the second switching state may be switched to a closed state.
In some embodiments, the step of "obtaining a state of the first switch or the second switch, and switching the state of the first switch or the second switch according to the state" may further include the following process:
acquiring a second state of the second switch;
performing a state switching operation on the first switch and the second switch based on the second state.
Specifically, the second state of the second switch is obtained, and the second state may be a plurality of states, for example, the second state may be an open state or a closed state, where an open-to-state transition may indicate that the circuit where the second switch is located is opened, and a closed state may indicate that the circuit where the second switch is located is connected.
Specifically, the state switching operation may be performed on the first switch and the second switch according to the second state of the second switch. For example, the second state may be open or closed, and when the second state is open, the state of the second switch may be switched to the closed state and the state of the first switch may be switched to the open state; when the second state is closed, the state of the second switch may be switched to an open state and the state of the first switch may be switched to a closed-open state.
When the access current is larger than the preset threshold value, the states of the first switch and the second switch are detected, and the states of the first switch and the second switch are switched, so that the battery can be effectively protected, and the battery is prevented from being damaged due to overlarge charging current.
In some embodiments, the charge control method may further include the steps of:
and if the charging current is less than or equal to a preset threshold value, performing charging operation on the first battery.
Specifically, when the charging current is less than or equal to the preset threshold, the charging current may be a normal charging current, and the terminal battery may be directly charged. When the terminal battery is charged, the first switch state can be switched to the closed state to perform charging operation on the first battery.
According to the scheme, when the charging power supply is detected to be connected, the voltages at two ends of the resistor are obtained; determining a charging current based on the voltage and a resistance value; comparing the charging current with a preset threshold value; if the charging current is larger than a preset threshold value, acquiring the state of the first switch or the second switch, and switching the state of the first switch or the second switch according to the state. In the embodiment, the charging current is compared with the preset current threshold value by acquiring the charging current, and then the charging state of the first battery and the charging state of the second battery are controlled, so that the power consumption of the batteries can be reduced, and the efficiency of the charging control of the terminal is improved.
Referring to fig. 3, fig. 3 is a schematic flowchart illustrating a second charging control method according to an embodiment of the present disclosure. In this embodiment, the specific application scenarios of the charging control method may be as follows:
201. and when the terminal detects that the charging power supply is connected, the voltage at the two ends of the resistor is obtained.
In this embodiment, when the user performs the charging operation on the terminal, the terminal may detect that the charging power supply is accessed, wherein the user may connect the terminal with the power supply through the charging wire, that is, may perform the charging operation on the terminal.
When the terminal detects that the charging power supply is connected, the voltage at the two ends of the resistor is obtained, and the voltage value at the two ends of the resistor can be a first voltage value and a second voltage value. For example, the first voltage value may be 5V, and the second voltage value may be 3V.
202. And the terminal processes the acquired voltage and the resistance value of the resistor to obtain the charging current.
Specifically, after the terminal acquires the first voltage value and the second voltage value at the two ends of the resistor, the resistance value of the resistor can be acquired. Wherein the resistance value may be obtained by reading resistance value data stored in the memory.
Further, after the terminal obtains the first voltage value, the second voltage value and the resistance value, the first voltage value, the second voltage value and the resistance value may be operated according to a preset calculation formula, so as to obtain the access current.
For example, the first voltage value may be 5V, the second voltage value may be 3V, the resistance value may be 2 Ω, and the preset calculation formula may be (Va1-Va2)/Ra, where Va1 represents the first voltage value, Va2 represents the second voltage value, and Ra represents the resistance value, and the access current I may be 1A by processing according to the preset calculation formula. The current value of the terminal access current can be obtained through a preset calculation mode, and the access current is conveniently compared with a preset current threshold value.
203. And the terminal compares the charging current with a preset current threshold value and judges whether the charging current is smaller than the preset current threshold value or not.
Specifically, after the terminal calculates the access current according to the above steps, the access current may be compared with a preset current threshold. The preset current threshold may be the maximum safe current that the terminal can access, that is, the current below the preset current threshold may charge the terminal battery normally without damaging the battery performance.
For example, the access current may be 0.5A, 1.8A, etc., the preset threshold may be 1.5A, and when the access current is 0.5A, it may be determined that the access current is smaller than the preset threshold, step 204 is executed; when the access current is 1.8A, it can be determined that the access current is greater than the preset current, and step 205 is executed.
204. The terminal detects the first switch state and carries out switching operation on the first switch state and the second switch state according to the first switch state.
Specifically, the state switching operation of the first switch and the second switch in this step may refer to the steps in the above embodiments, which are not described herein,
205. the terminal switches the first switch state to perform charging operation on the first battery.
When the access current of the terminal is less than or equal to the preset current threshold, the access current at the moment can be represented as safe current, and the terminal can perform charging operation on the battery. The terminal comprises two batteries, namely a first battery and a second battery, and the first battery can be charged firstly when the charging operation is carried out. For example, the terminal may switch the state of the first switch to a closed state, which is the transfer of access current to the first battery, thereby charging the first battery.
According to the scheme, when the charging power supply is detected to be connected, the voltages at two ends of the resistor are obtained; determining a charging current based on the voltage and resistance values; comparing the charging current with a preset threshold value; if the charging current is larger than a preset threshold value, acquiring the state of the first switch or the second switch, and switching the state of the first switch or the second switch according to the state. In the embodiment, the charging current is compared with the preset current threshold value by acquiring the charging current, and then the charging state of the first battery and the charging state of the second battery are controlled, so that the power consumption of the batteries can be reduced, and the efficiency of the charging control of the terminal is improved.
