Embodiment Construction

[0038] When the digital electronic device is connected to the PC, the original intention of the user may be to transfer files instead of charging, but the plug-and-charge method will still charge the battery through USB_VBUS when the PC is connected to the mobile phone, and the battery power is relatively low. Under sufficient conditions, the plug-and-charge method is undoubtedly a waste of battery charge and discharge times, especially the charge and discharge of plugging and unplugging USB_VBUS in a short period of time will cause greater damage to the battery and seriously affect its service life.

[0039] In order to solve the above problems, an embodiment of the present invention provides an intelligent charging method, using this method to manage the battery charging process as follows: figure 1 shown, including:

[0040] Step 101, detecting the type of external charging power supply;

[0041] In this step, when an external charging power supply is detected, it is neces...

Abstract

The invention discloses an intelligent charging method and a device. The field of mobile communication is related, and the problem that the plug-play charging mode affect the service life of a battery. The method comprises the following steps: detecting the type of an external charging power supply; if the type of the power supply is USB_VBUS power supply with the voltage value within a legal range, detecting the current electric quantity of the battery; and when the current electric quantity of the battery is not less than the preset charging threshold value, rejecting to charge. The technical method provided with by the invention is suitable for digital electronic products which can be charged by a USB HOST port.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an intelligent charging method and device. Background technique [0002] The mobile phone has become an indispensable communication tool in people's daily life, and the service life of the mobile phone battery is a problem that has plagued users for a long time. After using it for a period of time, the basic functions of the mobile phone itself are all normal, but the standby time of the battery is greatly reduced . [0003] At present, most mobile phones and other digital electronic products on the market use 5pin or 8pin (the difference from the 5pin interface is that the headphone signal is added) mini USB charging interface, and the external charging source is compatible with the power adapter (CHARGER, only supports charging) and USB HOST interface (such as PC USB_VBUS, which supports charging and file transfer at the same time). That is to say, whether plugging into CH...
