Embodiment 1

[0057] Please refer to figure 1 , an embodiment of the present invention provides an electronic device, such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, or other electronic devices with a charging module. This electronic device includes:

[0058] Device body 1;

[0059] A rechargeable power supply 2 is set in the device main body 1;

[0060] A charging module 3, arranged in the device main body 1, connected to the rechargeable power source 2, for charging the rechargeable power source 2;

[0061] The processor 4 is arranged in the device main body 1 and connected with the charging module 3 .

[0062] Wherein, the device main body 1 is the part surrounded by the casing of the electronic device. In the device main body 1 , a rechargeable power source 2 , a charging module 3 , and a processor 4 are arranged.

[0063] Specifically, the rechargeable power source 2 is a battery of an electronic device, specifically, a lithium battery, a nickel...

Embodiment 2

[0099] Such as figure 2 As shown, the embodiment of the present invention provides a charging module, including:

[0100] charging unit 31;

[0101] A control unit 32, configured to control, according to a control signal, whether the control unit and the charging unit are in a connected state or in a non-connected state, and the connection duration of the connected state;

[0102] Wherein, the charging unit is used to detect the change of the current magnitude on the charging unit when it is in the non-charging state and switches from the non-connected state to the connected state with the control unit, and when the connection continues During the time, the duration of the current on the charging unit is detected, and based on the change in the magnitude of the current and the duration of the current, the fast charging mode of the charging module is turned on.

[0103] Wherein, the charging unit 31 includes:

[0104] The charging chip 311 has at least the fast charging mod...

Embodiment 3

[0115] Based on the same inventive concept, an embodiment of the present invention also provides an information method, which can be applied to the electronic device in the first embodiment, and can also be applied to the charging module in the second embodiment.

[0116] Please refer to image 3 , the method includes:

[0117] Step 101: When the charging unit is in a non-charging state and is not connected to the control unit, detect that the magnitude of the current on the charging unit is a first magnitude;

[0118] Step 102: When the charging unit is in a non-charging state and switches from the non-connected state to the connected state, detect that the current on the charging unit is a second magnitude, and within the duration of the connection in the connected state , detecting the duration of the current on the charging unit;

[0119] Step 103: Obtain a change in current magnitude based on the first magnitude and the second magnitude, and start the fast charging mode...

Abstract

The present application provides an electronic device and a charging module. The electronic device includes: a device main body; a rechargeable power supply; a charging module connected to the rechargeable power supply for charging the rechargeable power supply; a processor connected to the charging module connection; the charging module includes: a charging unit; a control unit, configured to control whether the control unit and the charging unit are in a connected state or in a non-connected state according to a control signal sent by the processor, and the connection The connection duration of the state; the charging unit is used to detect the change of the current magnitude on the charging unit when it is in the non-charging state and switches from the non-connected state to the connected state with the control unit, and During the duration of the connection, the duration of the current on the charging unit is detected, and when the magnitude of the current changes and the duration of the current satisfies a preset condition, the fast charging mode of the charging module is turned on.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device and a charging module. Background technique [0002] With the development of electronic technology, more and more electronic devices have entered people's lives, such as smart phones, smart watches, notebook computers, tablet computers, etc. These electronic devices have brought great convenience to people's lives. [0003] In order to meet the requirements of mobility and portability, electronic equipment usually has a rechargeable power supply and a charging module used in conjunction with the rechargeable power supply. A rechargeable power source for electronic devices to charge. [0004] Generally speaking, the charging module has two charging modes: normal charging mode and fast charging mode. The fast charging mode takes less time than the normal charging mode to complete the same charging capacity, so people usually use the fast charging mode whe...
