Description

technical field [0001] The invention belongs to the technical field of battery charging, in particular to a multifunctional power supply system based on a double-variable intermittent pulse algorithm and a charging method thereof. Background technique [0002] At present, mobile devices using rechargeable lithium batteries as energy storage components are developing rapidly. At the same time, the high usage rate and high energy consumption of devices have put forward new and higher requirements for lithium battery charging methods and charging algorithms. However, most of the domestic power supply systems still use the wired charging method. In many occasions, the charging is limited and the charging method is not flexible. Some power supply systems with wireless charging methods also have a relatively simple implementation method. The charging algorithm used by the charging system is still the traditional two-stage or three-stage charging, and the very few pulse charging m...
