Abstract

The invention provides a charging method, comprising the steps of detecting state information of an electronic device; sending the state information to a charger based on a communication connection channel between the charger and the electronic device to enable the charger to regulate output charging current based on the state information; and charging a battery based on the charging current output by the charger. When the charger provides power for the electronic device, the electronic device sends the state information generated in the charging process to the charger, so that the charger can regulate power of power supply electronic device based on the state information so as to regulate the power for the electronic device in real time according to the related state information in the charging process of the electronic device; the control ability of a charging IC (integrated circuit) in the charging process is scattered; the charging IC can independently judge and regulate the charging process without needing the electronic device; and even if the charging IC is in failure, the charger can regulate the charging power in the charging process for the electronic device based on the state information, so that the charging safety is improved.

Description

technical field [0001] The present invention relates to the field of electronic equipment, and more specifically, relates to a charging method, a charger and electronic equipment. Background technique [0002] With the development of electronic technology, more and more electronic devices are used in various fields, and the charging safety of electronic devices is becoming more and more important. [0003] In the prior art, the electronic device is charged in the following manner: the charger outputs a fixed power to the electronic device, and the electronic device converts the fixed power into a voltage and a charging current that meet battery charging requirements through a charging IC (Integrated Circuit). Output to the battery to charge the battery. In this process, since the charging IC undertakes an important intermediate control link in the charging process, the power control, such as overvoltage and overcurrent related to charging, are all controlled by the charging...
