Detailed Description
At present, when the electronic device is charged through the power supply device, the charging current is generally controlled by the electronic device, which may cause the charging current to be inconsistent with the charging parameter of the power supply device, thereby reducing the charging efficiency.
In order to make those skilled in the art better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.

101: the method includes acquiring a first charging parameter of a power supply device for charging the electronic device. The first charging parameter is used for indicating the maximum value which can be adopted by the power supply equipment when the electronic equipment is charged.
For example, the first charging parameter may include a charging current, a battery capacity, and a charging voltage drop rate, where the charging current is a maximum charging current that the power supply device may employ when charging the electronic device, and the charging current that the power supply device may employ when charging the electronic device cannot exceed the maximum charging current. The battery capacity is the maximum amount of power provided by the power supply device, the charging voltage drop rate is the maximum charging voltage drop rate that the power supply device can reach when charging the electronic device, and when the charging voltage drop rate of the power supply device reaches the maximum charging voltage drop rate, the charging current of the power supply device needs to be reduced, so that the charging voltage drop rate is reduced.
In the embodiment of the present invention, one obtaining manner of the first charging parameter is: the identity information of the power supply equipment is identified, and the first charging parameter of the power supply equipment is obtained according to the identity information of the power supply equipment. The method specifically comprises the following steps: and acquiring a first charging parameter of the power supply equipment from the network based on the identity information of the power supply equipment.
The first charging parameter obtained in the network is generally provided by a manufacturer, and the manufacturer may provide the first charging parameter that is not consistent with its own product in order to allow more consumers to use the power supply devices produced by the manufacturer, which may cause the subsequent charging to fail to achieve the expected effect, so in order to obtain a more accurate first charging parameter, an embodiment of the present invention further provides another obtaining manner of the first charging parameter, where the obtaining manner may be: and searching a parameter database to obtain a first charging parameter corresponding to the power supply equipment.
The electronic equipment can search the first charging parameters corresponding to the power supply equipment in the parameter database through communication with the server.
In the embodiment of the present invention, the electronic device may also search for the first charging parameter corresponding to the power supply device in the parameter database based on the identity information of the power supply device, so that the parameter database stores the first charging parameter and also needs to store the identity information of the power supply device. When the identity information of the power supply equipment for charging the electronic equipment is matched with the identity information of a certain power supply equipment in the parameter database, the first charging parameter of the power supply equipment matched with the identity information is the first charging parameter to be acquired.
The identity information of the power supply equipment is used for indicating the type of the power supply equipment, and can be a commodity code of the power supply equipment, the commodity code of the power supply equipment can be obtained by identifying a bar code or a two-dimensional code on the power supply equipment, and after the commodity code of the power supply equipment is obtained, a first charging parameter of the power supply equipment corresponding to the commodity code is obtained from a network or a parameter database based on the commodity code. The corresponding power supply device may be any one of a power supply device, a portable power source, a generator, a solar charger, and even a USB (universal serial Bus) interface of a PC (Personal Computer) that provides power supply for the electronic device.
102: a charging mode of the electronic device is determined. The charging mode is used for indicating which parameter is adopted by the electronic equipment for charging, and the adopted charging parameter may be different in different charging modes. The charging mode in the embodiment of the present invention may include a fast charging mode and an energy efficient charging mode. The fast charge mode is a charge mode in which the electronic device is fully charged at the fastest speed, and the energy-efficient charge mode is a charge mode in which the power consumption of the power supply device is minimized.
In the embodiment of the present invention, one possible way to determine the charging mode is: determining a default charging mode of the electronic equipment, wherein the default charging mode can be any one of a quick charging mode and an energy-efficient charging mode, and when the power supply equipment charges the electronic equipment, the default charging mode is preferentially adopted for charging.
Another possible way to determine the charging mode is: according to the method for selecting the charging mode of the electronic device by operating the operation body, in the embodiment of the present invention, each charging mode may be displayed on a UI (user interface) of the electronic device as a corresponding icon, as shown in fig. 2, so that the currently selected icon may be determined according to the operation position of the operation body, and the charging mode associated with the icon is the selected charging mode, which includes the following specific processes:
the method comprises the steps that first input operations of an operation body are obtained through a sensing device of the electronic equipment, and each first input operation forms an operation position on the sensing device, so that after the first input operation is obtained, a first input position of the first input operation is obtained through the sensing device, and the charging mode corresponding to an icon marked at the first input position is determined to be the currently selected charging mode.

103: and determining a second charging parameter adopted in the charging mode according to the charging mode determined by the electronic equipment and the first charging parameter.
104: and charging the electronic equipment according to the second charging parameter.
After the charging mode of the electronic device is determined, a second charging parameter in the charging mode may be determined based on the first charging parameter and the charging mode of the power supply device, and the electronic device may be charged according to the second charging parameter. For example, when the determined charging mode is the energy-efficient charging mode, the highest conversion ratio current in the first charging parameter may be used as the charging current of the second charging parameter, and then the electronic device may be charged based on the charging current of the second charging parameter, where the highest conversion ratio current is used to maximally convert the power amount of the power supply device into the power amount of the electronic device, so that the charging with the highest conversion ratio current as the charging current of the second charging parameter may minimize the power loss of the power supply device, that is, provide the power amount of the power supply device to the electronic device as much as possible.
Accordingly, when the determined charging mode is the fast charging mode, the process of determining the second charging parameter may be as shown in fig. 3, and includes the following steps:
1031: the method comprises the steps of obtaining a standard charging current preset by the electronic equipment, wherein the standard charging current is the maximum charging current adopted when the electronic equipment is charged and is used for indicating the maximum allowable charging current in the charging process, and the electronic equipment is damaged when the standard charging current is exceeded.

1033: and when the comparison result shows that the charging current of the first charging parameter is smaller than the standard charging current, taking the charging current of the first charging parameter as the charging current of the second charging parameter.
When the comparison result shows that the charging current of the first charging parameter is smaller than the standard charging current, it shows that the maximum charging current which can be reached by the power supply equipment is not enough to reach the standard charging current, at this time, the charging current of the first charging parameter needs to be adopted to charge the electronic equipment, otherwise, the voltage drop rate of the power supply equipment exceeds the limited value, and the power supply equipment is damaged.
1034: and when the comparison result shows that the charging current of the first charging parameter is greater than or equal to the standard charging current, taking the standard charging current as the charging current of the second charging parameter.
When the comparison result shows that the charging current of the first charging parameter is greater than the standard charging current, it shows that the maximum charging current that can be reached by the power supply device already exceeds the standard charging current, and at this time, the standard charging current needs to be adopted to charge the electronic device, otherwise, the current in the electronic device is increased too fast, and the electronic device is damaged.
According to the technical scheme, after the charging mode of the electronic equipment is determined, the second charging parameter in the charging mode can be determined based on the first charging parameter and the charging mode of the power supply equipment, and the electronic equipment is charged according to the second charging parameter, so that the electronic equipment can be charged by adopting the second charging parameter corresponding to the determined charging mode, and the charging efficiency in different charging modes is improved.
Furthermore, the charging current of the second charging parameter can be determined by integrating the charging currents of the electronic equipment and the power supply equipment, so that the charging current adopted in the charging process can meet the requirements of the electronic equipment and the power supply equipment on the charging current, and the damage rate of the electronic equipment or the power supply equipment is reduced.

For example, the first charging parameter may include a charging current, a battery capacity, and a charging voltage drop rate, where the charging current is a maximum charging current that the power supply device may employ when charging the electronic device, and the charging current that the power supply device may employ when charging the electronic device cannot exceed the maximum charging current. The battery capacity is the maximum amount of power provided by the power supply device, the charging voltage drop rate is the maximum charging voltage drop rate that the power supply device can reach when charging the electronic device, and when the charging voltage drop rate of the power supply device reaches the maximum charging voltage drop rate, the charging current of the power supply device needs to be reduced, so that the charging voltage drop rate is reduced.
In the embodiment of the present invention, one possible way for the obtaining unit 11 to obtain the first charging parameter is: the identity information of the power supply equipment is identified, and the first charging parameter of the power supply equipment is obtained according to the identity information of the power supply equipment. The method specifically comprises the following steps: and acquiring a first charging parameter of the power supply equipment from the network based on the identity information of the power supply equipment.

The parameter database may be stored in the server, and the obtaining unit 11 may search for the first charging parameter corresponding to the power supply device in the parameter database by communicating with the server.
In the embodiment of the present invention, the obtaining unit 11 may also search for the first charging parameter corresponding to the power supply device in the parameter database based on the identity information of the power supply device, so that the parameter database stores the first charging parameter and also needs to store the identity information of the power supply device. When the identity information of the power supply equipment for charging the electronic equipment is matched with the identity information of a certain power supply equipment in the parameter database, the first charging parameter of the power supply equipment matched with the identity information is the first charging parameter to be acquired.
The identity information of the power supply equipment is used for indicating the type of the power supply equipment, and can be a commodity code of the power supply equipment, the commodity code of the power supply equipment can be obtained by identifying a bar code or a two-dimensional code on the power supply equipment, and after the commodity code of the power supply equipment is obtained, a first charging parameter of the power supply equipment corresponding to the commodity code is obtained from a network or a parameter database based on the commodity code. The corresponding power supply device may be any one of a power supply device, a portable power source, a generator, a solar charger, and even a USB (Universal Serial Bus) interface of a PC (Personal Computer) that provides power supply for the electronic device.
A mode determination unit 12 for determining a charging mode of the electronic device. The charging mode is used for indicating which parameter is adopted by the electronic equipment for charging, and the adopted charging parameter may be different in different charging modes. The charging mode in the mode determination unit 12 in the embodiment of the present invention may include a fast charging mode and an energy-efficient charging mode. The fast charge mode is a charge mode in which the electronic device is fully charged at the fastest speed, and the energy-efficient charge mode is a charge mode in which the power consumption of the power supply device is minimized.
In the embodiment of the present invention, one possible way for the mode determining unit 12 to determine the charging mode is: determining a default charging mode of the electronic equipment, wherein the default charging mode can be any one of a quick charging mode and an energy-efficient charging mode, and when the power supply equipment charges the electronic equipment, the default charging mode is preferentially adopted for charging.
Another possible way for the mode determination unit 12 to determine the charging mode is: according to the method for selecting the charging mode of the electronic device by the operation of the operation body, in the embodiment of the present invention, each charging mode may be displayed on a UI (User Interface) of the electronic device as a corresponding icon, as shown in fig. 2, so that the currently selected icon may be determined according to the operation position of the operation body, and the charging mode associated with the icon is the selected charging mode, which includes the following specific processes:
the method comprises the steps that first input operations of an operation body are obtained through a sensing device of the electronic equipment, and each first input operation forms an operation position on the sensing device, so that after the first input operation is obtained, a first input position of the first input operation is obtained through the sensing device, and the charging mode corresponding to an icon marked at the first input position is determined to be the currently selected charging mode.
And the parameter determining unit 13 is configured to determine a second charging parameter used in the charging mode according to the charging mode determined by the electronic device and the first charging parameter.
And the charging unit 14 is used for charging the electronic equipment according to the second charging parameter.
After the charging mode of the electronic device is determined, a second charging parameter in the charging mode may be determined based on the first charging parameter and the charging mode of the power supply device, and the electronic device may be charged according to the second charging parameter. For example, when the determined charging mode is the energy-efficient charging mode, the parameter determination unit 13 may use the highest conversion ratio current in the first charging parameter as the charging current of the second charging parameter, and then the charging unit 14 charges the electronic device based on the charging current of the second charging parameter.
The highest conversion ratio current is used for converting the electric quantity of the power supply equipment into the electric quantity of the electronic equipment to the maximum, and thus, the charging current with the highest conversion ratio current as the second charging parameter can enable the electric quantity loss of the power supply equipment to be the lowest, namely, the electric quantity of the power supply equipment is provided for the electronic equipment as far as possible.

The first determining subunit 133 is configured to, when the comparison result indicates that the charging current of the first charging parameter is smaller than the standard charging current, take the charging current of the first charging parameter as the charging current of the second charging parameter.
When the comparison result shows that the charging current of the first charging parameter is smaller than the standard charging current, it shows that the maximum charging current which can be reached by the power supply equipment is not enough to reach the standard charging current, at this time, the charging current of the first charging parameter needs to be adopted to charge the electronic equipment, otherwise, the voltage drop rate of the power supply equipment exceeds the limited value, and the power supply equipment is damaged.
And the second determining subunit 134 is configured to, when the comparison result indicates that the charging current of the first charging parameter is greater than or equal to the standard charging current, use the standard charging current as the charging current of the second charging parameter.
When the comparison result shows that the charging current of the first charging parameter is greater than the standard charging current, it shows that the maximum charging current that can be reached by the power supply device already exceeds the standard charging current, and at this time, the standard charging current needs to be adopted to charge the electronic device, otherwise, the current in the electronic device is increased too fast, and the electronic device is damaged.
According to the technical scheme, after the charging mode of the electronic equipment is determined, the charging device provided by the invention can determine the second charging parameter in the charging mode based on the first charging parameter and the charging mode of the power supply equipment, and charge the electronic equipment according to the second charging parameter, so that the electronic equipment can be charged by adopting the second charging parameter corresponding to the determined charging mode, and the charging efficiency in different charging modes is improved.
