Embodiment 1

[0042] Such as figure 1 As shown, the embodiment of the present invention provides a charging management method, which is applied to the adapter side supporting fast charging, and specifically includes the following steps:

[0043] Step S101, the adapter is connected to the mobile terminal;

[0044] Step S102, the adapter judges whether the fast charging identifier issued by the mobile terminal is detected, if so, execute step S103; otherwise, execute step S104;

[0045] In this step, the mobile terminal issuing the fast charging identifier refers to a mobile terminal supporting fast charging.

[0046] In this step, the fast charging identifier is preferably a periodic square wave, which may be a periodic square wave with a frequency of 10KHz, an amplitude of 3V, and a duty cycle of 50%. Of course, the specific form of the above-mentioned fast charging identifier is only one of many implementation methods. Any form of identifier can be agreed between the mobile terminal supp...

Embodiment 2

[0052] Such as figure 2 As mentioned above, the embodiment of the present invention provides a charging management method, which is applied to the side of the mobile terminal supporting fast charging, and specifically includes the following steps:

[0053] Step S201, the mobile terminal supporting fast charging detects that the adapter is connected;

[0054] In this step, the mobile terminal connects to the adapter through the USB interface, and sends the fast charging identifier to the adapter by outputting the fast charging identifier to the DP (positive pole of the USB data line) signal line of the USB interface. Charging identifier.

[0055] Further, in this step, the way for the mobile terminal to detect whether the adapter is connected includes: when a device is connected to the USB interface, the mobile terminal applies a fixed voltage to the DP signal line of the USB interface, and detects the DM (USB Whether the voltage of the negative pole of the data line) signal...

Embodiment 3

[0061] Such as image 3 As shown, the embodiment of the present invention provides an adapter that supports fast charging, which specifically includes: a flag detection unit 310, a first main control unit 320, and a voltage conversion unit 330, wherein:

[0062] The flag detection unit 310 is used to detect whether the fast charging identifier issued by the mobile terminal side is received after the adapter is connected to the mobile terminal, and send the detection result to the first main control unit 320;

[0063] Preferably, in the flag detection unit 310, the fast charging identifier refers to a periodic square wave with a frequency of 10KHz, an amplitude of 3V, and a duty cycle of 50%;

[0064] Further, the flag detection unit 310 is also configured to convert the identifier into a high-level signal when detecting the fast-charging identifier, and use the high-level signal as a signal for receiving the fast-charging identifier. The detection result of the character is s...

Abstract

The invention discloses a charge management method, a charge management device and a charge management system, wherein the method comprises steps that when an adapter is accessed to a mobile terminal, whether a rapid charge identifier issued by the mobile terminal side is detected is judged; if so, the mobile terminal is charged based on a predetermined rapid charge mode; if not, and the mobile terminal is charged based on a standard charge mode. With the adoption of the charge management method, the charge management device and the charge management method, not only are the rapid charge of the specific mobile terminal and the shortening of charge time under the premise of not increasing a special charge interface realized, but also the charge of a nonspecific terminal product under the condition of guaranteeing safety is realized; and therefore, the generality of the adapter is improved greatly.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a charging management method, device and system. Background technique [0002] Mobile terminal products are increasingly favored by consumers, including smart phones and UFI products, and the battery capacity of these two types of products is also increasing. The battery capacity of smart phones is mostly 2000MAh, and UFI products are even more More than 4000mAh, unfortunately, the power consumption of smart phones and other products is getting bigger and bigger, which means that users need to charge after a short period of use. Now the mainstream charging current is about 1A, so it takes about 2.5 hours to charge a 2000MAh battery, and 4.5 hours to charge a 4000MAh battery. The battery capacity is still increasing, so the charging time will be longer, more than 6 hours. will crash. However, if the charging current is increased to 3A, the charging time will...
