Abstract

The invention discloses a charger, a charging method and device, and a control chip, and belongs to the technical field of the power supply. The charger comprises the control chip and a rectifier circuit which is electrically connected to the control chip; the control chip is used to acquire a battery voltage of a battery and to generate a control signal according to the battery voltage and an expected charging efficiency; and the rectifier circuit is used to, according to the control signal, convert a power voltage of an input power supply into a charging voltage for outputting. According to the invention, the control chip is used to acquire the battery voltage of the battery, the control signal is generated according to the battery voltage and the expected charging efficiency, and the rectifier circuit is used to, according to the control signal, convert the power voltage of the input power supply into the charging voltage for outputting, so that the problems of low charging efficiency and great loss in relevant charging methods are solved; and the charging efficiency is improved, the loss is reduced, and the overheating problem of the charger is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of power supply, in particular to a charger, a charging method, a device and a control chip. Background technique [0002] With the explosive growth of electronic devices such as mobile phones and tablet computers, while their functions meet the various needs of users, there are also new requirements for the battery life of these electronic devices. R&D personnel increase the battery life by expanding the battery capacity, but when the battery capacity is expanded, the charging time of the battery will also increase accordingly. [0003] In order to shorten the charging time of the battery, R&D personnel usually realize it by increasing the charging voltage. Taking a mobile phone as an example, under normal circumstances, the charging voltage of the mobile phone battery is a constant 5V. According to Ohm's law, when the resistance of the charging circuit remains unchanged, the charging current can...
