Problems solved by technology

Due to the lack of battery presence detection contacts, the device cannot normally detect whether the battery is in place when plugged into the charger
In MT, electric energy is needed to support MT to start work when charging, but because the current provided by the charger is generally relatively small, at this time, MT full-load work will cause MT to crash or restart.
Therefore, due to the inability to correctly judge whether the battery is in place, it will cause certain failures when the MT is charging and working normally.

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] In the present invention, the first switching device is connected in series between the charging power source and the positive pole of the battery, and the controller controls the conduction and disconnection of the first switching device through its first control pin. When the first switch device is turned on, the battery is charged by the charging power source; when the first switch device is turned off, the controller detects the presence of the positive pole of the battery. The electronic device can effectively avoid abnormal operation of the device caused by charging in the case of poor contact or failure of the battery according to the presence of the battery.

[0035] In addition, the second switching device is connected in series between the first s...

Abstract

The electronic equipment inspection system in charging inspects the positioning status of the two contacts method of the battery. The controller turns off the charging circuit instantly through serial connection in the battery charging circuit, and inspects the positive electrode of the battery to acquire two contacts battery positioning information.

Description

technical field [0001] The invention relates to electronic equipment, in particular to a power supply system of the electronic equipment. Background technique [0002] With the advancement of technology and the integration of industries, the development of mobile value-added services will be colorful. The development of mobile value-added services has three main directions: the first is to fully tap the potential of mobile communication systems, and provide mobile value-added services based on mobile communication networks and Internet Protocol ("IP" for short) technology; The second type is the mobile value-added service separated from the mobile communication network. The typical example is mobile TV. Although there are many ways to realize this kind of service, the best development prospect is the way of directly receiving broadcast TV signals from the traditional TV network; The third category is the integration of consumer electronics products and mobile terminals (MT ...
