Abstract

The invention provides a charger and a control method thereof. The charger comprises a charging unit used for converting the input alternating current into a needed first direct current so as to charge a charging load, and a control unit used for judging whether the charging load is fully charged or not according to the working frequency of the charging unit when the charging load is charged by the charging unit, so as to determine whether to continuously charge the charging load or not. By virtue of the scheme provided by the invention, whether the charging load is fully charged or not can bejudged by detecting the working frequency of a switching power supply; and after it is detected that the charging load is fully charged, the charger can automatically disconnect from the charging load.

Description

technical field [0001] The invention relates to the control field, in particular to a charger and a control method thereof. Background technique [0002] With the continuous improvement of the performance of smart devices, the battery power consumption is getting faster and faster. The aging of batteries and the rapid decline in power storage capacity of smart devices such as mobile phones and tablets have become a difficult problem to solve. Most users have developed the habit of using it during the day and charging the device when they go to bed at night, sometimes charging it continuously for one night or half a day. In fact, it does not take so long to charge mobile phones and other devices. Long-term charging will cause empty consumption of the charger, and will also cause great damage to the battery and equipment, and may even cause a safety hazard of battery explosion. Contents of the invention [0003] The main purpose of the present invention is to overcome the d...
