Determination system, terminal charging method, terminal and charger of charger style

Abstract

The invention discloses a judging system of charger pattern, terminal charging method and terminal and charger in the electronic equipment domain, which is characterized by the following: connecting terminal and kinds of charger through uniform hardware interface; setting different testing pins in the hardware interface according to different chargers; making different testing pins of charger and testing pins of terminal possess different levels; charging the charger pattern according to measuring the level of testing pin; reducing the false probability of charger pattern.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a terminal and its charging technology. Background technique [0002] Undoubtedly, today is the era of handheld devices, among which mobile phones have the largest market and usage, and therefore the technological progress of mobile phones is extremely rapid, which can be seen from the related interface technologies. For example, in order to more precisely control the chip power consumption in the handheld device, the PowerWise Power Management Interface (PWI for short) and the like have been proposed. [0003] Since it is quite common for mobile phones to have a USB interface, the USB interface was originally used to connect with a personal computer (Personal Computer, referred to as "PC") for the uplink and downlink transmission and synchronization of information. The development trend, one is to charge the mobile phone through the USB interface, and the other is to upgrade...

AI Technical Summary

Problems solved by technology

[0011] In practical applications, the existing technology has the following problems: the mobile phone / terminal may not be able to correctly identify the charger type, causing hidden dangers during charging

[0012] The main reason for this situation is that when the mobile phone / terminal is connected to the main device and the USB interface of the main device is abnormal, the mobile phone / terminal cannot correctly identify the charger type

If the mobile phone is connected to the PC, and the USB of the PC is short-circuited due to a fault, and the D+ / D- data line cannot be in the disconnected state, the mobile phone / terminal will mistake the USB charger for the power charger, and the charging current is too large. The main equipment brings reliability risks and even security risks
