Problems solved by technology

However, if two of the power supply pins are in poor contact, the actual overcurrent capability is only 2.5A. If the charging current is still charged at 5A at this time, the charging interface is likely to be burned
[0005] To sum up, the existing charging scheme cannot take into account the speed and reliability of charging

Embodiment 1

[0051] see figure 2 , propose a mobile device according to a first embodiment of the present invention, especially a mobile device such as a mobile phone or a tablet. The mobile device includes a channel detection module, a current determination module and a charging module, wherein:

[0052] Channel detection module: used to detect whether each current transmission channel is connected properly when the charging interface is connected to the charger.

[0053] Specifically, when the charging interface of the mobile device is connected to the charger, the mobile device will not charge immediately, but firstly conducts a reliability test on the formed current transmission channel. In the embodiment of the present invention, there are at least two current transmission channels, and the channel detection module needs to detect each current transmission channel, judge whether each current transmission channel is connected normally, and send the detection result to the current det...

Embodiment 2

[0073] see image 3 , the mobile device of the second embodiment of the present invention is proposed. The difference between this embodiment and the first embodiment is that a prompting module is added, and the channel detection module also sends the detection result to the prompting module. The prompting module is used for: according to the detection result Judging whether there is an abnormal connection of the current transmission channel, and sending a prompt message when there is an abnormal connection of the current transmission channel.

[0074] The prompt information may be sound information, such as a beeping sound or voice prompt information, or may be displayed text and / or image information, or a combination of the two. In order to remind the user that the connection of the transmission channel is abnormal, it is recommended that the user reconnect the charger.

[0075] Therefore, the user can find out the connection abnormality in time, reconnect the charger, char...

Embodiment 3

[0090] see Figure 6 , propose a charging method for a mobile device according to a third embodiment of the present invention, said method comprising the following steps:

[0091] S11. After the charging interface is connected to the charger, it is detected whether each current transmission channel is connected normally.

[0092] Specifically, when the charging interface of the mobile device is connected to the charger, the mobile device will not charge immediately, but firstly conducts a reliability test on the formed current transmission channel. In the embodiment of the present invention, there are at least two current transmission channels, and the mobile device needs to detect each current transmission channel to determine whether each current transmission channel is connected normally.

[0093] Optionally, the mobile device may detect each current transmission channel one by one in the following manner: connect the currently detected current transmission channel and dis...

Abstract

The invention discloses a mobile device and a charging method thereof. The mobile device comprises a channel detection module, a current determination module and a charging module, wherein the channel detection module is used for detecting whether each current transmission channel is normal in connection or not after a charging interface is connected with a charger, the current determination module is used for determining a safety current according to a detection result, and the charging module is used for charging the mobile device with a charging current which does not exceed the safety current. Therefore, the connection reliability test is performed on the charging interface by detecting whether each current transmission channel is normal in connection before charging, and a safe charging current is determined according to the detection result; when all current transmission channels are normal in connection, charging is performed with the maximum current which can be borne by the charging interface; and when only a part of current transmission channels are normal in connection, charging is performed with the maximum current which can be borne by the part of the current transmission channels. The charging speed is ensured, the charging reliability is also improved, and the charging interface is prevented from being burnt due to abnormal connection.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a mobile device and a charging method thereof. Background technique [0002] The charging interface of traditional mobile devices is the MICRO B interface of the USB2.0 standard. However, as the battery capacity of mobile devices increases, the traditional MICRO B interface can no longer meet the needs of fast charging. At present, the charging interface of mobile devices has gradually developed into the USB 3.0 standard TYPE C interface. Compared with the traditional MICRO B interface, the biggest advantage of the TYPE C interface is that the TYPE C interface supports a large current of 3A or even 5A (MICRO B only Can support 1.5A), so it is beneficial to increase the charging speed. [0003] Such as figure 1 As shown, the reason why the TYPE C interface can provide a larger charging current is that compared with the MICRO B interface, the power pin (VBUS / GND pin) has been...
