Intelligent charging device and charging control system and control method

Abstract

The invention provides an intelligent charging device and a charging control system and control method. The intelligent charging device comprises a base, a bearing body, a first monitoring component, an electromagnet, a permanent magnet and a control component, wherein a plug is arranged on the base, the bearing body is arranged on the base, the first monitoring component is used for monitoring charging electric quantity of a device to be charged in real time, the electromagnet and the permanent magnet are arranged in a matching way and are oppositely and relatively arranged between the base and bearing body, a charging interface of the device to be charged is connected or disconnected with the plug through absorption or repulsion between the electromagnet and the permanent magnet, the control component is used for controlling absorption / repulsion actions between the electromagnet and the permanent magnet according to the charging electric quantity of the device to be charged. By the charging control system and control method, magnetic force and magnetic pole conversion of the electromagnet can be controlled, electrical connection between the device to be charged and the plug of the charging device is timely cut after the device to be charged is fully charged, and the problems such as explosion, short circuit and reduction of battery service life caused by long-term connection between a battery of the device to be charged and a charger are prevented.

Description

Technical field [0001] The invention relates to the field of mobile terminal charging equipment, in particular to a smart charging device and a charging control system and control method for controlling the charging device. Background technique [0002] At present, mobile terminals have a huge market share. Mobile terminals such as mobile phones have become indispensable supplies in people's lives. Most mobile terminals are equipped with lithium batteries, so they need to be charged frequently. According to the insufficient remaining battery power, the charging time is average. It varies from several to several hours. Since users generally do not monitor the charging status of mobile terminals at all times, the charger cannot be unplugged in time after the battery is fully charged, which causes the batteries of mobile terminals such as mobile phones to become unstable due to overcharging. Cause battery explosion, fire and other problems, the resulting personal and property losses...

Problems solved by technology

[0002] At present, the market share of mobile terminals is huge, and mobile terminals such as mobile phones have become indispensable in people's lives. Most mobile terminals are equipped with lithium batteries, so they need to be charged frequently. According to the lack of remaining battery power, the charging time is generally It ranges from several hours to several hours. Because users generally do not monitor the charging status of mobile terminals all the time, and cannot unplug the charger in time after the battery is fully charged, the batteries of mobile terminals such as mobile phones become unstable due to overcharging. Cause battery explosion, fire and other problems, resulting in immeasurable personal and property losses. The solution in the prior art is to monitor the fully charged state of the mobile terminal through the system, and then stop charging through the IC chip current limit. The terminal is always connected to the charger. In actual use, there is an overcharging situation in which it is already fully charged but is judged to be not fully charged and continues to charge, which leads to danger and reduces battery life. Due to many smart devices The built-in battery of the mobile terminal is not replaceable, so the above problems also directly lead to the reduction of the service life of the mobile terminal, and also cause a waste of power resources
