Abstract

The invention discloses a system for ensuring automatic powering-off of an intelligent mobile terminal after full charging. The system comprises a USB connector used to connect a charger, and an APP mounted in an intelligent mobile terminal. A wireless control unit is arranged between the charger and the intelligent mobile terminal, and the wireless control unit includes a controller chip. The USB connector is connected with a power switch MOS tube and a low-dropout linear regulator through a +5V power supply line. The low-dropout linear regulator is used to provide +3.3V voltage for the controller chip. The output end of the power switch MOS tube is connected with the USB connector. The controller chip is connected with a crystal oscillator. The invention further provides a method for ensuring automatic powering-off of an intelligent mobile terminal after full charging. The charging state of the intelligent mobile terminal is read through the APP of the intelligent mobile terminal, which is simple, intuitive and accurate. The problem that inaccurate and false judgment is caused by factors such as device aging for a traditional detection circuit for judging 'full charge' is completely solved.

Description

technical field [0001] The invention relates to a method and system for ensuring that an intelligent mobile terminal is automatically powered off after being fully charged. Background technique [0002] At present, smart terminal devices such as mobile phones and PADs consume a lot of power. People are used to charging at night, but mobile phones will cause overcharging overnight, which will greatly damage the battery life of smart terminal devices. Moreover, due to the uneven quality of chargers, some chargers do not have a charging protection circuit at all, and cannot play a basic role in protecting the device being charged. safety incidents. [0003] At present, there are smart chargers with overcharge protection function known as "full power cut off" on the market, which use a series of algorithms to detect whether the connected device is "full charge", and then prevent the flow of current, and finally realize as The smart mobile terminal is fully charged, and the bat...
