detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

first embodiment

According to an aspect of an embodiment of the present invention, a power display method of a mobile power supply is provided, as shown in FIG. 1 , the method includes:

Step 101: Receive battery status information of a mobile power source through a communication connection with the mobile power source.

The power display method of a mobile power supply according to an embodiment of the present invention is applied to a mobile terminal, and the mobile terminal may be an intelligent electronic device such as a mobile phone or a tablet computer. When the mobile terminal is charged by a mobile power supply, it needs to establish a connection with the mobile power supply, for example, through a data line connection, so that the mobile power supply can transmit its own electric energy to the mobile terminal through the data line to charge the mobile terminal. However, in the embodiment of the present invention, the mobile power supply needs to send the battery status information detected by itself to the mobile terminal, so a communication connection needs to be established between the mobile power supply and the mobile terminal.

Therefore, before step 101, it also includes:

Establish a communication connection with a mobile power supply according to a predetermined communication protocol.

Wherein, the manner of establishing the communication connection is not limited to a wired type, and may also be a wireless type. Specifically, the wired type, as shown in Figure 9, can establish a communication connection through the differential data lines (ie D+ and D- data lines) or the positive line (USB_5V) between the mobile terminal and the mobile power supply, so that The mobile terminal can receive the battery status information sent by the mobile power supply through the differential data line or the positive line of the data line.

Step 102: Determine the remaining power information of the mobile power supply according to the battery state information, and display the remaining power information on a display screen of the mobile terminal.

Wherein, the battery has different voltage values under the condition of remaining different electric power. Therefore, the battery status information can be represented by the voltage information of the battery, and when the battery status information received by the mobile terminal is voltage information, step 102 is specifically:

According to the pre-stored correspondence between the battery voltage and the power of the mobile power supply, the power information corresponding to the voltage information is determined, and the power information is used as the remaining power information of the mobile power supply.

That is, after the mobile power supply obtains the voltage information of the battery through its own detection circuit, it directly sends the voltage information to the mobile terminal, and the mobile terminal needs to further determine the remaining power information of the battery according to the voltage information. Wherein, for the mobile power supply, its internal battery has a voltage-to-power comparison graph, so in order for the mobile terminal to determine the corresponding power information based on the voltage information, the voltage-to-power comparison graph needs to be stored in the mobile terminal in advance. Therefore, the mobile terminal can determine the power information corresponding to the received voltage information according to the voltage-to-power comparison graph, and then display the power information on the display screen as the remaining power information of the mobile power supply.

In addition, the mobile power supply can also obtain the voltage information of the battery through its own detection circuit, and determine the power information corresponding to the obtained voltage information according to the voltage and power comparison curve of the battery stored in itself. The information is sent to the mobile terminal as battery status information, so that the mobile terminal directly displays it as the remaining power information of the mobile power supply after receiving the battery status information. Therefore, when the battery state information is the power information of the battery, step 102 is specifically:

The power information is directly used as the remaining power information of the mobile power supply.

In addition, if the display screen of the mobile terminal shows that the remaining power of the mobile power supply is less than a preset threshold, such as 30% of the total capacity of the mobile power supply, the mobile terminal can prompt the user to replenish the power supply for the mobile power supply in time, further improving the user experience.

As can be seen from the above, the power display method of the mobile power supply according to the embodiment of the present invention can receive the battery status information sent by the mobile power supply with which a communication connection has been established through the mobile terminal, and determine the remaining power information of the mobile power supply according to the battery status information, and then Displayed on the display screen, the user can clearly understand the remaining power of the mobile power supply, avoiding the situation of insufficient power when the user is out on a business trip, and greatly improving the user experience.

second embodiment

According to another aspect of the embodiments of the present invention, there is also provided a power display method for a mobile power supply, as shown in FIG. 2 , the method includes:

Step 201: Obtain battery status information of a mobile power supply.

The power display method of a mobile power supply according to an embodiment of the present invention is applied to a mobile power supply. Wherein, the mobile power supply has different voltage values when the remaining power is different. Therefore, the battery status information can be represented by the voltage information of the battery. In addition, the mobile power supply is provided with an analog-to-digital converter (ADC), so the mobile power supply can accurately detect the voltage information of the mobile power supply through its own ADC detection circuit. Therefore, when the battery state information is the voltage information of the battery, step 201 is specifically:

Detecting the voltage of the battery of the mobile power supply to obtain the voltage information.

Alternatively, after the mobile power supply detects the voltage of the battery through the ADC detection circuit and obtains the voltage information, it further determines the power information corresponding to the obtained voltage information according to the pre-stored voltage-to-power comparison curve. Then when the battery state information is power information, step 201 includes:

Detecting the voltage of the battery of the mobile power supply to obtain voltage information;

According to the pre-stored correspondence between the battery voltage and the electric quantity of the mobile power supply, the electric quantity information corresponding to the voltage information is determined.

In addition, before step 201, it also includes:

According to a predetermined communication protocol, a communication connection with a mobile terminal is established, and the charging circuit electrically connected to the mobile terminal is controlled to be disconnected until the battery state information is sent to the mobile terminal, and the connection with the mobile terminal is controlled. The charging circuit electrically connected to the terminal charges the mobile terminal.

Wherein, the manner of establishing the communication connection is not limited to wired or wireless. When the communication connection is established in a wired manner, the mobile power supply is connected to the mobile terminal through the data line, triggers the mobile power supply to start the boot process, and then performs handshake communication with the mobile terminal through the differential data line or the positive line of the data line to establish a communication connection. If the handshake communication between the mobile terminal and the mobile power supply fails, it means that the mobile power supply does not support the mobile terminal to display the power, which is an unofficial standard mobile power supply.

In addition, after the communication connection is established, the mobile power supply may suspend charging the mobile terminal, and charge the mobile terminal after step 202 . Because the mobile power supply is in a static no-load state when charging is not started, the most accurate detection of the voltage of the mobile power supply is at this time.

Step 202: Send the battery status information to a mobile terminal that establishes a communication connection with the mobile power supply.

Wherein, no matter whether the battery status information is represented by voltage information or power consumption information, it needs to be converted into a digital signal before being sent to the mobile terminal. Among them, when the battery status information is voltage information, the voltage of the battery can be detected first by the ADC detection circuit, and then the detected voltage is converted into digital voltage information; when the battery status information is power information, it can be detected first by the ADC detection circuit The voltage of the battery, and then convert the detected voltage into digital voltage information, and then determine the power information according to the comparison curve between the voltage and power of the battery. Among them, in order to simplify the processing method, the corresponding relationship between voltage and power can be stored , and directly store the power information in digital signals, so that the power information in the form of digital signals can be directly obtained according to the pre-stored correspondence between voltage and power.

After the mobile terminal receives the battery status information sent by the mobile power supply, the remaining power information of the mobile power supply determined according to the battery status information will be displayed on its own display screen, so that the user can clearly understand the remaining power of the mobile power supply, and avoid When the user is out on a business trip, there is insufficient power, which greatly improves the user experience.
