[0021] In the present embodiment, a charging method running on the above mobile terminal is provided. FIG. 3 is a flowchart of the charging method according to the embodiments of the present disclosure. As shown in FIG. 3, the flowchart includes the following steps:

[0022] In step S302, a voltage value or a current value output by the charger in the current charging mode is detected.

[0023] In the present embodiment, the voltage value or the current value output by the charger in the current charging mode can be detected according to a set detection period. The applied charging current value in the current charging mode can also be updated according to the battery state of the terminal and the current output current value of the charger, or the applied charging voltage value in the current charging mode can be updated according to the battery state of the terminal and the current output voltage value of the charger. The battery state includes, but is not limited to, at least one of the following: battery temperature, battery power, and battery capacity.

[0024] In step S304, the current charging mode is switched in a case where the voltage value or the current value output by the charger does not satisfy the corresponding charging voltage value or charging current value.

[0025] In the embodiment, when the current charging mode is the first charging mode, the current value of the charger output in the first charging mode needs to be detected, and when the current value of the charger output does not meet the corresponding charging current value, the current charging mode is switched from the first charging mode to the second charging mode, the second charging mode is the constant voltage charging mode, and the terminal is charged according to the corresponding charging voltage value in the second charging mode.

[0026] After the current charging mode is switched from the first charging mode to the second charging mode, the voltage value of the charger output in the second charging mode needs to be detected, and when the voltage value of the charger output does not meet the applied charging voltage value, the current charging mode is switched from the second charging mode to the third charging mode, the third charging mode is the constant current and constant voltage charging mode, and the terminal is charged according to the corresponding charging voltage value and charging current value in the third charging mode.

[0027] In an embodiment, the constant current mode and the constant voltage mode can be exchanged in sequence, and the terminal can select to use the constant current charging mode first or the constant voltage charging mode first according to the battery capacity of the terminal. If the battery capacity of the terminal is lower than a first preset threshold, the battery can be quickly charged through the constant current charging mode; or if the battery capacity of the terminal is higher than a second preset threshold, the battery can be prevented from overcharging through the constant voltage charging mode, thereby protecting the service life of the battery.

[0028] In an embodiment, when the current charging mode is the second charging mode, the voltage value of the charger output in the second charging mode needs to be detected, and when the voltage value of the charger output does not meet the corresponding charging voltage value, the current charging mode is switched from the second charging mode to the first charging mode, the first charging mode is the constant current charging mode, and the terminal is charged according to the corresponding charging current value in the first charging mode.

[0029] After the current charging mode is switched from the second charging mode to the first charging mode, the current value of the charger output in the first charging mode needs to be detected, and when the current value of the charger output does not meet the applied charging current value, the current charging mode is switched from the first charging mode to the third charging mode, the third charging mode is the constant current and constant voltage charging mode, and the terminal is charged according to the corresponding charging voltage value and charging current value in the third charging mode.

[0030] In one embodiment, before step S302 is performed, the type of the charger can be identified first, and in a case where the type of the charger is a predetermined type of charger, a charging capability package sent by the charger is received, and a corresponding charging current value is applied to the terminal for charging in a first charging mode, where the first charging mode is a constant current charging mode; or a corresponding charging voltage value is applied to the terminal for charging in a second charging mode, where the second charging mode is a constant voltage charging mode.

[0031] In the embodiment, in a case where the type of the charger is not a predetermined type of charger, the terminal is charged according to the type of the charger.

[0032] Through the above steps, the voltage value or the current value output by the charger in the current charging mode is detected, and in a case where the voltage value or the current value output by the charger does not satisfy the corresponding charging voltage value or the charging current value, the current charging mode is switched, thereby solving the problem that the actual output voltage and current of the charger are different from the charger specification book or the charging protocol, so that the terminal cannot be normally charged by using the charger, and achieving the effect that the terminal can be connected to more chargers for normal charging, and the charger outputs higher charging power.

[0033] FIG. 4 is another flowchart of a charging method according to an embodiment of the present disclosure, as shown in FIG. 4, the flowchart includes the following steps:

[0034] In step S401, after the terminal is connected to the charger, the terminal interacts with the charger to identify the type of the charger.

[0035] If it is identified that the type of the charger is a predetermined type of charger, a charging capability package sent by the charger is received. In one embodiment, the terminal identifies that the charger supports a Precision Power System (PPS) protocol, and the charger supporting the PPS protocol sends a charging capability package to the terminal. FIG. 5 is a schematic diagram of the charging package.

[0036] If the type of the charger is identified as a non-predefined type of charger, the terminal charges according to the type of the charger. In an embodiment, the terminal identifies that the charger is not a charger supporting the PPS protocol, and then continues to charge according to the type of the charger, and applies a voltage and a current corresponding to the type of the charger. In an embodiment, if the type of the charger is identified as a Dedicated Charging Port (DCP) type, 5V 1.5A charging is applied. In an embodiment, if the type of the charger is identified as a Quick Charge (QC) 2.0 type, 9V 1.5A charging is applied. In an embodiment, if the type of the charger is identified as a Power Delivery (PD) charger (not supporting the PPS protocol), a voltage and a current are applied according to a Power Delivery Object (PDO) charging capability package sent by the PD charger.

[0037] In step S402, if the battery level of the terminal is lower than the first preset threshold value at this time, a corresponding charging current value is applied to charge the terminal according to the first charging mode (constant current charging mode), and the current value output by the charger in the constant current charging mode is detected according to the set detection period. In the case where the current value output by the charger does not meet the corresponding charging current value, the current charging mode is switched from the first charging mode to the second charging mode (constant voltage charging mode).

[0038] In an embodiment, the terminal can first apply a current according to the constant current charging mode (first charging mode). After the terminal applies the current, the current charged by the terminal is detected in a detection period cycle in a subsequent charging period. If the expected current requirement is met, the constant current charging mode is continued. If the expected current is not detected to be charged to the terminal, the terminal is switched to the constant voltage charging mode (second charging mode). In an embodiment, the detection period cycle detection includes: setting the detection period to 5 seconds during charging, and then acquiring the battery state, current and other parameters of the terminal every 5 seconds, and adjusting the current applied by the terminal to the charger.

[0039] In step S403, a corresponding charging voltage value is applied to charge the terminal according to the second charging mode (constant voltage charging mode), and the voltage value output by the charger in the constant voltage charging mode is detected according to the set detection period. In the case where the voltage value output by the charger does not meet the corresponding charging voltage value, the current charging mode is switched from the second charging mode to the third charging mode (constant current constant voltage charging mode).

[0040] In an embodiment, after the terminal is switched from the first charging mode to the second charging mode, the terminal continues to apply voltage according to the constant voltage charging mode (the second charging mode). After the terminal applies voltage, the terminal continues to charge according to the constant voltage charging mode in a detection cycle in a subsequent charging period. If the voltage detected in the subsequent charging period meets the expected voltage requirement, the terminal continues to charge according to the constant voltage charging mode. If the voltage detected in the subsequent charging period does not meet the expected voltage requirement, the terminal switches to the constant current constant voltage charging mode (the third charging mode).

[0041] In step S404, the terminal is charged according to the third charging mode (the constant current constant voltage charging mode) with the corresponding charging voltage value and the charging current value.

[0042] In an embodiment, after the terminal is switched from the second charging mode to the third charging mode, the terminal continues to apply voltage and current according to the constant current constant voltage charging mode (the third charging mode). In an embodiment, the constant current constant voltage charging mode refers to the fixed voltage and current charging mode.

[0043] In an embodiment, when the terminal battery level is higher than the second preset threshold, for example, close to the full charge state, the charging process is suitable for the constant voltage charging mode, which ensures that the battery is not overcharged and protects the battery life. In an embodiment, the terminal close to the full charge state is connected to the PPS charger, which is preferably charged according to the constant voltage and constant current constant voltage charging mode. If the constant voltage charging mode cannot charge normally, the terminal is charged according to the constant current constant voltage charging mode.

[0044] When the terminal battery level is higher than the first preset threshold and lower than the second preset threshold, the constant current charging mode or the constant voltage charging mode is preferred. In an embodiment, the terminal not close to the full charge state is inserted into the PPS charger and is charged according to the constant current, constant voltage, and constant current constant voltage charging mode in sequence. The battery is quickly charged by the constant current charging mode. If the constant current charging mode cannot charge normally, the terminal is charged according to the constant current constant voltage charging mode. In an embodiment, the terminal not close to the full charge state is also charged according to the constant voltage, constant current, and constant current constant voltage charging mode in sequence. If the constant voltage charging mode cannot charge normally, the terminal is switched to the constant current charging mode to quickly charge the battery. If the constant current charging mode cannot charge normally, the terminal is switched to the constant current constant voltage charging mode.

[0045] Through the above steps, the embodiment of the present disclosure can charge according to the charging type when identifying that the type of the charger is a charger that does not support the PPS protocol. When identifying that the type of the charger is a PPS charger, the voltage and current are applied according to the constant current, constant voltage, and constant current and constant voltage charging modes until the charger can normally output the voltage and current. The charger that does not conform to the PPS specification on the market and the charger that writes a private protocol can also be compatible, thereby improving the compatibility of the charger and improving the user experience. The charger has high universality and is suitable for all PPS fast charging terminal products with high compatibility. Without increasing the hardware cost, the charger is simple and easy to apply.

[0046] Embodiment one

[0047] The embodiment is a case of a PPS charger that normally outputs the voltage and current according to the charger specification.

[0048] The terminal first applies the voltage and current according to the constant current charging mode. After the terminal applies the current, the current charged to the terminal is cyclically detected in the detection period during the subsequent charging period, the voltage and current meet the expected requirements, and the charging according to the constant current charging mode is continued.

[0049] Embodiment two

[0050] The embodiment is a case of a PPS charger that cannot output the current according to the charger specification, but can output the voltage according to the charger specification.

[0051] For example, the power delivery object (PDO) charging capability package of a certain PPS charger is as follows: 3-11V, 0-6A charging is supported, and actually the terminal applies a charging current higher than 5A, and the charger cannot normally output the current.

[0052] 1. The terminal first applies the current according to the constant current charging mode. After the terminal applies the current, the current charged to the terminal is cyclically detected in the detection period during the subsequent charging period. The terminal applies 6A current in the constant current charging mode, the charging circuit of the charger outputs 6A, and the voltage is output according to the voltage difference between the charger and the terminal battery. The charger cannot normally output 6A current, and the terminal detects that the expected current is not charged to the terminal, and then the terminal switches to the constant voltage charging mode.

[0053] 2. The terminal continues to apply the voltage according to the constant voltage charging mode. The terminal applies 11V voltage in the constant voltage charging mode, and the charger adjusts the output voltage to 11V. At this time, the voltage difference between the charger and the terminal battery determines the size of the current. According to the different voltage values applied by the terminal, the charger can normally output the voltage values. The terminal detects that the voltage output meets the expected requirements, and continues to charge according to the constant voltage charging mode.

[0054] Embodiment three

[0055] This embodiment is the case of PPS charger which can not output voltage according to charger specification, but can output current according to charger specification.

[0056] For example, the PDO charging capability package of a certain PPS charger is as follows: support 3-11V, 0-6A charging. In fact, the terminal applies charging current higher than 10.5V charger cannot normally output current.

[0057] The terminal first applies current according to the constant current charging mode. After the terminal applies current, the terminal detects the current charged to the terminal in the detection cycle of the subsequent charging period. The terminal applies 6A current in the constant current charging mode, the charger adjusts the circuit to output 6A, and outputs voltage according to the voltage difference between the charger and the terminal battery. The charger normally outputs 6A current, and the terminal detects the expected current charged to the terminal, so the terminal continues to charge in the constant current charging mode.

[0058] Embodiment Four

[0059] This embodiment is the case of PPS charger which can not output current and voltage according to charger specification.

[0060] For example, the PDO charging capability package of a certain PPS charger is as follows: support 3-11V, 0-6A charging. In fact, the charger cannot output current higher than 5A, and the charger cannot output voltage higher than 10V.

[0061] 1. The terminal first applies current according to the constant current charging mode. After the terminal applies current, the terminal detects the current charged to the terminal in the detection cycle of the subsequent charging period. The terminal applies 6A current in the constant current charging mode, the charger adjusts the circuit to output 6A, and outputs voltage according to the voltage difference between the charger and the terminal battery. The charger cannot normally output 6A current, and the terminal detects that no expected current is charged to the terminal, so the terminal switches to the constant voltage charging mode.

[0062] 2. The terminal continues to apply voltage according to the constant voltage charging mode. The terminal applies 11A voltage in the constant voltage charging mode, and the charger adjusts the output voltage to 11V. At this time, the voltage difference between the charger and the terminal battery determines the size of the current. The charger cannot normally output 11V voltage, and the terminal detects that no expected voltage is charged to the terminal, so the terminal switches to the constant current constant voltage charging mode.

[0063] 3. The terminal continues to apply voltage and current according to the constant current constant voltage charging mode, such as 9V 3A.
